This is backed up by Verbeek's visit in 1880, during which he took samples from a "fresh-looking" lava flow on the northern coast.
Louis Doremus Huntoon, E.M., M.A. (1869-1937) was an American mining engineer, born at Paterson, New Jersey, and educated at the New York College of Pharmacy and the School of Mines of Columbia University (1895). He was employed as a chemist and assayer in Colorado in 1895-96 and mining and metallurgical engineer in New York in 1896-1903, and he remained in New York afterwards. He became consulting engineer in New York City after 1911.
Around this time, Galena beat the nearby camps of Caribou and Hardscrabble in the election for the first post office. By the end of 1877, 400 people were living in Galena, and it had 75 homes and two smelters. A mail line was built from Deadwood to Galena and Virginia City. The town later boasted a physician, assayer, notary, shoemaker, two hotels, two saloons, another livery yard, an opera house, a tin shop, and two more sawmills.
Thomas was born in Camborne, Cornwall, England, the son of Josiah Thomas Sr. and Ann Rablin. He went to Mexico as a child with his father, a mine manager, and later worked in mines in Cornwall. He travelled to Australia in the mid-1880s and worked at the Barrier Range, near Broken Hill. He was appointed as a member of a royal commission on collieries in 1886 and worked as a mining captain and assayer in 1890.
The discovery prompted the gold rush that established Southern Cross and the Yilgarn Goldfield, and led to the subsequent rich finds at Coolgardie and Kalgoorlie that established the Eastern Goldfields. After returning to Perth, Anstey was appointed Government Assayer in 1889. In 1890 he was living in the Cockburn Sound area, and from 1893 he was a farmer at Jarrahdale. From 22 August 1893 until July 1894, Anstey was a nominated member of the Western Australian Legislative Council.
Howe served as principal of Longmeadow High School of Massachusetts in 1879. He moved west where he became the principal of the Academy of Albuquerque in New Mexico from 1879–1881, and was involved in mineral prospecting serving as an assayer for prospectors in Albuquerque until 1882. Howe married Abbie A. Waite on May 22, 1882, and together had three children. From 1883–1889, Howe served as the Professor of Mathematics and Astronomy at Buchtel College in Akron, Ohio.
James J. McKinley and Ernest Darragh were contractors supplying ties to the T&NO; along Mile 103 from North Bay. On the banks of Long Lake (now called Cobalt Lake), south of Haileybury, they noticed metal in a road cut. On August 30, 1903 they staked a claim on a timber limit owned by John Rudolphus Booth, and sent several samples to an assayer in Montreal. These proved to have 4,000 ounces of silver per ton.
From 1905 to 1907, he was employed as the director of the gymnasium and coach of the football and basketball teams at the University of Montana in Missoula, Montana. Schule also worked as a school teacher in Wausau and Milwaukee, Wisconsin, and as an assayer and bacteriologist in Utah and Chicago. He later worked as an engineer and superintendent for Westinghouse Lamp Company. In 2008, he was posthumously inducted into the University of Michigan Track & Field Hall of Fame.
Having trained in his father's business as an assayer, Percival Johnson established his own firm in 1817.Percival Norton Johnson at Oxford Dictionary of National Biography He specialised in the assaying and refining of precious metals particularly gold imported from Brazil: he perfected a method of extracting the Palladium from the gold therefore improving the gold's colour. He became a Fellow of the Royal Society in 1846. He went into full partnership with George Matthey, a stockbroker, in 1851.
A lone prospector, John Campbell Miles, stumbled upon one of the world's richest deposits of copper, silver and zinc during his 1923 expedition into the Northern Territory. When Miles inspected the yellow-black rocks in a nearby outcrop, they reminded him of the ore found in the Broken Hill mine that he had once worked at. Upon inspection these rocks were weighty and heavily mineralised. A sample sent away to the assayer in Cloncurry confirmed their value.
131 In 1620 Maffeo Barberini wrote a poem entitled Adulatio Perniciosa in Galileo's honor.The Galileo Project An official, Giovanni di Guevara, said that The Assayer was free from any unorthodoxy.William A. Wallace, Galileo, the Jesuits and the Medieval Aristotle, (1991), pp.VII, 81-83 Also in the book, Galileo theorizes that senses such as smell and taste are made possible by the release of tiny particles from their host substances, which was correct but not proven until later.
Frost married Bertha K. Marcum on 1 October 1914. Frost continued to work as a lawyer following the conflict and was drafted following the entry of the United States into the First World War, which he had penned several newspaper opinion pieces against in the years preceding it, citing his experience during the 1913-1914 strike. Frost died in 1955. His son Hildreth Frost, Jr. would be appointed as assayer for the Denver Mint in 1970.
The conventional stamp mill in which the ore was crushed and the gold amalgamated with mercury was almost useless in refining Cripple Creek ore. At first, the process didn't work well, but it was improved by John Rothwell, a consultant who was the foremost expert on chlorination at the time. A young Daniel C. Jackling was hired as assayer through Charles MacNeill, the start of his noted career. In December 1895, the chlorination mill at Lawrence burned to the ground.
4, "The Electric Telegraph Company", archived 1 July 2016. He was editor of the Adelaide Examiner from June to July 1842 and was elected president of the Port Adelaide Mechanics' Institute at its inaugural meeting in 1851. Davy was a director and manager of the Adelaide Smelting Company and became chief assayer of the Government Assay Office in Adelaide in February 1852. Davy was appointed assay master in Melbourne in July 1853 until the office was abolished in October 1854.
He attended school in the United States and Germany and was graduated from the Royal School of Mines at Clausthal, Germany, in 1874, taking the degree of mining engineer and metallurgist. During the next three years, he was chemist, assayer and assistant superintendent of the Delaware Lead Mills at Philadelphia. He began his career in technical journalism in 1876, when he covered the Centennial Exposition for British, German and Cape Town, South Africa, papers. He then joined the Metallurgical Review in 1877.
While there, he is recognized by assayer Talbot Bartlett, who knows him from a previous case. Later, Chan guesses that prospector Pete is stealing ore from the mine, and persuades him to guide him, Tommy and Birmingham to the mine through his secret passageway. However, when they arrive, Tommy and Birmingham find Pete's body. Chan eventually surmises that much cheaper Mexican gold is being smuggled in and sold in the US at a huge profit by Driscoll and his men.
Lab-created stones tend to have a more vivid color since impurities common in natural stones are not present in the synthetic stone. Synthetics are made free of common naturally occurring impurities that reduce gem clarity or color unless intentionally added in order to provide a more drab, natural appearance, or to deceive an assayer. On the other hand, synthetics often show flaws not seen in natural stones, such as minute particles of corroded metal from lab trays used during synthesis.
Philip III continued with the shield type of 1572 (inscribed PHILIPVS III), also in denominations of 1, 2, 4, and 8 reales. Mexico City coins were dated from 1607. Potosí, where the position of mint assayer was auctioned off to the highest bidder, only began dating coins in 1617, after a scandal involving an illegal debasement of the cob coinage (1610–1617). The dates were added to the obverse inscription, but because of the irregular shape of a cob, they are rarely legible.
For the next four weeks he worked in the McCracken Mine, wielding a pick and shovel. Ed learned about the McCracken Mine's recently arrived assayer, Richard Gird, who had a reputation as an expert. Taking his last three ore samples, Ed Schieffelin asked Gird if he thought they were worth assaying. Gird took a look and said he'd get back to Ed. Three days later, Al shook Ed out of his bunk and said Gird wanted to see him now.
Born in Dunedin in 1880, Henderson was educated at Otago Boys' High School. He then studied at the University of Otago, where he completed his BSc and Diploma in Mining and Certificate of Metallurgical Chemist and Assayer in 1902. He graduated MA from Victoria University College in 1906, and DSc from Otago and Victoria in 1908. He served as director of the Reefton School of Mines from 1903 to 1911, when he joined the New Zealand Geological Survey as a mining geologist.
His science degree was awarded with first class honours in geology and palaeontology, having studied volcanic dykes in the Triassic rocks around Sydney under Professor (Sir) Edgeworth David. Upon graduation, Waterhouse was employed as an assistant assayer at the Sydney branch of the Royal Mint until 1926.Towards the end of his time at the Royal Mint he was awarded his Doctor of Science degree in 1924. He married Beatrice Talbot Stretton at Waverley on 12 September 1902 in a Methodist ceremony.
He further recommended that this building be of the same dimensions as the existing Assay Office building, but of cheaper construction. Therefore, the walls of the building were constructed entirely of chamferboard, on a concrete slab, with a fibro cement roof. He requested that the construction of the office and storeroom be dealt with "as an urgent matter" because he wanted the building completed before the Assayer was appointed. The second building was constructed in 1917, adjacent to the original Assay Office.
Karl Friedrich Plattner (2 January 1800 – 22 January 1858) was a German metallurgical chemist. He was born at Kleinwaltersdorf, near Freiberg in the Electorate of Saxony, on 2 January 1800. His father, though only a poor working miner, found the means to have him educated first at the Bergschule (mining school) and then at the Bergakademie of Freiberg. After he had completed his courses there in 1820 he obtained employment, chiefly as an assayer, in connexion with the royal mines and metal works.
After thoroughly exploring the ridges, Miles approached some copper gougers who were also unable to identify the mineral, but advised Miles to send specimens to Cloncurry where the Government Assayer would analyse them. The samples were found to be very high in lead and silver. Once Miles received the assay results he was certain that he had made an important discovery. He began mining the ore and when the warden asked him to name his leases, he chose the name, Mount Isa.
The Weighing Committee measured the weight of coins from the pyx, checking them against the weight required by law. The Assaying Committee worked with the Philadelphia Mint's assayer as he measured the precious metal content of some of the coins. In some years there was a Committee on Resolutions—in 1912, it urged that a leaflet be published for visitors to the Mint's coin collection, and that a medal be struck to commemorate the collection. The full Assay Commission adopted that committee's report.
Morris, M. 1966; Ardill 2017 Broad acreage field trials conducted in 1935-36 on local pastoral stations, that involved fencing to exclude stock and rabbits in order to facilitate natural regeneration of the indigenous flora, convinced him of the efficacy of the natural regeneration method of degraded land restoration.Ardill 2017 Albert was also possessed of extensive administrative and communication skills. His professional employment as an assayer involved responsible administrative duties, and he utilised this experience to good effect in his volunteer conservation work.
Rawlings was born near Bristol, England to William Rawlings and his wife Margaret Eliza (née Edwards). Trained for the sea, he sailed to Sydney in 1869 and on to New Zealand where he engaged in seafaring on the west coast for several years. In 1875, he was back in Australia and working as a miner in the Parkes goldfields. Moving to Queensland and settling in the Herberton district in 1883, he undertook several jobs including labourer, assayer, miner, and prospector.
While three Cowboys were inside looting the safe and robbing the customers, two Cowboys outside were confronted by citizens who recognized that a robbery was in progress. When assayer J. C. Tappenier exited the Bon Ton Saloon next door, they ordered him to go back in. He refused and the robbers, armed with Winchester repeating rifles, killed him with a shot to the head. Cochise County Deputy Sheriff D. Tom Smith was having dinner with his wife across the street at the Bisbee House.
In 1849 they returned to Adelaide, where he opened a chemist's shop at 37 Hindley Street, then in August 1851 to c. 51 Rundle Street He visited the gold diggings at Forest Creek, Victoria, perhaps working as an assayer and gold buyer, and returned to his Rundle Street shop with new advertising directed at miners. The shop was taken over early in 1853 by James Parkinson. and throughout 1853 to May 1854 he was selling bottled English porter and stout at Blyth's Building, Hindley Street.
He was educated privately and at the Royal School of Mines (1861–1865). He was appointed Assistant to the Master of the Mint and then Chemist of the Royal Mint (1869), Professor of Metallurgy at the School of Mines (1880) and Chemist and Assayer to the Royal Mint (1882–1902). He developed procedures for the analysis of alloy constituents and an automatic recording pyrometer used to record temperature changes in furnaces and molten materials;. He became a world authority on the technical aspects of minting coins.
Fred W. Carlisle then "jumped" the claim, and remained in control of the Monte Cristo Gold Mine until his death in 1946. Carlisle had been assayer in the Randsburg Mining District, where he had reportedly suffered financial losses, and came to Mill Creek seeking to revive his expiring fortunes. Under Carlisle, the Monte Cristo Gold Mine reached the zenith of its activity, during the years from 1923 to 1928. Gold-bearing ore was recovered from two groups of quartz veins about a thousand feet apart.
In The Assayer, Galileo offered a more complete physical system based on a corpuscular theory of matter, in which all phenomena—with the exception of sound—are produced by "matter in motion". Galileo identified some basic problems with Aristotelian physics through his experiments. He utilized a theory of atomism as a partial replacement, but he was never unequivocally committed to it. For example, his experiments with falling bodies and inclined planes led him to the concepts of circular inertial motion and accelerating free-fall.
' Guiducci concluded with an attempt to reconcile experimental evidence with theological arguments, but firmly asserted the primacy of data gathered through observation. Galileo was very pleased with Guiducci's efforts, proposing him for membership of the Accademia dei Lincei in May 1621 (although he did not actually become a member until 1625). In public, Galileo insisted that Guiducci, and not he, was the author of the Discourse on Comets. In 1623, in the opening section of Il Saggiatore (The Assayer) he complained: > 'One might have thought that Sig.
Nevill, E. Report of the government astronomer for 1903, p. 4 From 1893 daily observations of the magnetic declination were made at the observatory. In November 1887 Nevill was appointed also as Government Chemist and Official Assayer for Natal, which further reduced the time available for astronomical research. His chemical work was mainly of a routine nature and included analyses of geological samples for gold and other metals, analyses of soil samples for agricultural purposes, the examination of high explosives and detonators, and toxicological investigations.
Three years later, he also obtained his MSc in metallurgical engineering from the same school, and in 1918 Harvard University awarded him his Doctor of Science degree. After his graduation in 1910 he started as an assayer for the Custer mining company in South Dakota, and later that year he accepted an appointment as an instructor at Case Western Reserve University in Cleveland. In 1916 he was promoted to appointed assistant. In 1914 he also started as a consulting engineer in the Cleveland-area.
A coin assayer is often assigned to each mint or assay office to determine and assure that all coins produced at the mint have the correct content or purity of each metal specified, usually by law, to be contained in them. This was particularly important when gold and silver coins were produced for circulation and used in daily commerce. Few nations, however, persist in minting silver or gold coins for general circulation. For example, the U.S. discontinued the use of gold in coinage in 1933.
Debasing a coin, or otherwise tampering with it, was a very serious crime, often punishable by death in many civilizations. For example, in 1649, the directors of the Spanish colonial American Mint at Potosi, in what is today Bolivia, were condemned to death for seriously debasing the coinage. The initials of the assayer as well as the mint mark were immediate identifiers when the coins were inspected. In some cases the symbols found in the field of ancient Greek coins indicated mints, not magistrates.
Rosita was founded in late 1872 by prospectors attracted by discoveries of silver. The town was composed of tents and log cabins, but soon had stores, carpenters, a hotel, saloon, blacksmith shop, and an assayer. By 1874 the town had more than a thousand residents and 400 buildings. A U.S. post office opened in 1874, and in September 1874 the Rosita Index began as a weekly newspaper. Rosita took the seat of Custer County away from Ula (now also a ghost town) in 1878.
ChemCentre has an extensive history, and traces its origins of protecting and supporting the community back to the 1890s and the Western Australian gold rush. With the passing of the Explosives Act 1895, the State Government appointed the first official Government Analyst, along with the Government Assayer. In 1933, these two offices were amalgamated and later incorporated in the then Mines Department. After being located at various times in Perth and Fremantle, the Government Chemical laboratories was formed and located in East Perth in 1944.
"Bob Smart's Dream" is a poem written by Robert W. Service while he lived in Whitehorse, Yukon, Canada. He presented it on March 19, 1906, at a banquet held to honour J.P. Rogers, the superintendent of the White Pass and Yukon Route. The real-life Bob Smart had been the government assayer at Whitehorse since 1903. Imagining that "fifty years had sped," as Service wrote, Smart discovered a vastly different Whitehorse from the frontier town he knew that merely supplied transportation to and from the Klondike.
Adrian Monk and Natalie Teeger arrive in Trouble, California, a small town known for an unsolved train robbery that happened there in 1962. In the 1840s, Trouble was also home to one of Monk's distant relatives, an assayer who possessed skills invaluable to the small town, and exhibited many of the same obsessive compulsive traits as Adrian. Monk discovers that these seemingly uncorrelated historical facts are connected to the murder of a museum security guard in Trouble who was a retired San Francisco police officer.
Although the bulk of Buttrey's academic output concerned coins of antiquity, Buttrey was directly involved in a controversy regarding Western American gold bars that he described as counterfeit. This followed earlier, apparently uncontroversial, work in which he was able to identify certain Mexican gold bars as counterfeit, primarily by cataloguing anachronistic assayer markings. That earlier work was capped by Buttrey's 1973 talk, "False Mexican Colonial Gold Bars" at the International Numismatic Congress. In 1984, the American Numismatic Society passed a resolution supporting Buttrey's assertions.
Mitchell studied in the evenings at the Working Men's College of Melbourne; he gained a certificate in geology in 1911 and subsequently worked for the Department of Metallurgical Geology and Mineralogy. He established his own businesses, first as a gold assayer, then as S. R. Mitchell & Co., which was a refiner of precious metals from the 1920s, then Mitchell's Abrasives in 1930 to manufacture sandpaper. He also worked as a consultant to mining ventures and was a member of Australasian Institute of Mining and Metallurgy and a foundation member of the Royal Australian Chemical Institute.
Edward IV appointed him Cofferer to the Household and later Clerk of Works, where he was a reliable civil servant to the palatial royal household. During 1483 he obtained offices from April onwards on the death of the old king. The Comptroller of the Exchange, Assayer of the Mint were all his from an affinity for the Liveried Guilds. But later that year he was re-appointed Chief Clerk and Keeper of the Rolls of the King's Bench, so that by the time of Richard III's coup d'état he became Secretary.
In the 16th century, Tycho Brahe and Michael Maestlin demonstrated that comets must exist outside Earth's atmosphere by measuring the parallax of the Great Comet of 1577. Within the precision of the measurements, this implied the comet must be at least four times more distant than from Earth to the Moon. Based on observations in 1664, Giovanni Borelli recorded the longitudes and latitudes of comets that he observed, and suggested that cometary orbits may be parabolic. Galileo Galilei one of the most renowned astronomers to date, even attempted writings on comets in The Assayer.
Jonathan Hyslop, History Workshop Journal, Spring 2001 He became active in the Irish Nationalist circle in the Transvaal. In 1898 Noonan became a member of the Executive Committee of the Transvaal '98 Commemoration Committee - established to arrange a celebration of the centenary of the Irish uprising. One of those who helped plan the Johannesburg commemoration was an Irish immigrant called Arthur Griffith, and serving on the committee was an assayer of the mine, John MacBride. The Boer government saw militant Irish Nationalism as a potential ally against the British.
In 1862 he was elected to the seat of Light in the House of Assembly to fill the casual vacancy opened when F. S. Dutton was appointed Agent-General, and sat from May 1862 to November 1862, when Parliament was dissolved. He did not seek re- election. He moved to Thames, New Zealand in 1869 where he joined his brothers William Rowe (MHR for Thames) and Abel Rowe, there he was advertising himself as a Practical Mining Manager and Assayer in February 1870. By 1872 he was in Sydney, again advertising himself.
Nevill was elected a Fellow of the Royal Society in 1888 and Nevill was appointed Government Chemist and Official Assayer for Natal, which included the duty for latter post of acting as pathologist in cases of suspected poisoning. ;Later lunar theory work Observations of the Moon at Greenwich compared with Hansen's Tables, with Nevill's corrections leading to new values of elements and new lunar tables prepared. No publication of this work occurred due to lack of funds at Durban. Work was restricted more and more to routine observations and in 1911 the observatory closed.
He was elected in 1863 a Fellow of the Chemical Society and in 1886 a Fellow of the Royal Society. In 1884 Robert Warrington Jr. married Helen Louisa (1855–1898), third daughter of George H. Makins, M.R.C.S., chief assayer to the Bank of England. Robert Warington Jr. and his first wife had five daughters: Elizabeth (Betty) born in 1888; Margaret born in 1890; Dorothy, born in 1892; and twins, Katherine and Helen (Kitty and Nell) born in 1897. In 1902 he married Rosa Jane, daughter of Frederick Robert Spackman, M.D., of Harpenden.
Coming upon the couple, he lets Larry ride Champion, Autry's horse, into White Water to get help, while he stays with Helen for protection. Larry returns shortly and the three ride into White Water. In Los Robles, Helen's father, a prospector, enlists the help of a local assayer, Ben Luber, to evaluate the quality of some ore he has extracted. Ben tells Tom Ellis that he will need mining equipment to mine the ore, and his willing to lend him the money for it, in exchange for an interest in the mine.
In 1723 Philip named him viceroy of Peru, a position which he took up in May of the following year. His term in office was distinguished by a campaign against fraud and corruption in the government, and reform of the royal treasury and tax collection. He took steps to strengthen the mita, the forced labor of Indigenous in the silver mines, and thus to stimulate the production of the metal. He sent to jail the Count of San Juan de Lurigancho, director of the mint, as well as the assayer, for producing false coins.
Drake received his first academic appointment in 1967 as full professor at the University of Toronto after a career as a financial consultant. During that time he had begun his studies of the works of Galileo and translated Galileo's Dialogue Concerning the Two Chief World Systems (1953), parts of four of Galileo's works in Discoveries and Opinions of Galileo (1957), and Galileo's The Assayer in The Controversy of Comets (1960), co-authored with C. D. O'Malley.Jed Z. Buchwald, Noel M. Swerdlow. "Eloge: Stillman Drake, 24 December 1910-6 October 1993".
Born in Rome in a noble family. Brother of the better-known Virginio Cesarini (1596–1624) to whom Galileo Galilei (1564–1642) addressed Il Saggiatore [The Assayer] (Rome, 1623) in the form of a letter. Ferdinando Cesarini, as a referendarius utriusque signaturae and patron, corresponded with Benedetto Castelli (1577/8-1643), who described the Galilean thermoscope to him in a letter of September 20, 1638. Father Castelli also invited him to spread the Discorso sulla calamita [Discourse on the loadstone], also dedicated to Cesarini, within a limited circle of "trust" people.
He trained as a pharmacist in Darmstadt, then studied chemistry under Justus von Liebig at the University of Giessen (whose sister Katharina Elisabeth Liebig he married in 1841). He worked at the mint in Paris as an assayer, and in 1841 became an associate professor of technology at Giessen. From 1847 to 1853 he was a full professor at the university, then relocated to Munich, where he became a technical director at the Nymphenburg Porcelain Manufactory. In 1863 he went to Brunswick () to teach classes in chemistry at the polytechnic school.
Domingo de Eyzaguirre y Arechavala (July 17, 1775 – April 22, 1854) was a Chilean politician and philanthropist. He was born in Santiago, Chile, the son of the Basque Domingo Eyzaguirre Escutasolo and of María Rosa de Arechavala y Alday. He studied in the seminary of his native City, and showed remarkable aptitude for mathematics and chemistry. When scarcely nineteen years old he was appointed as assayer of the royal mint of Santiago, but resigned the next year, and devoted himself entirely to the cultivation of a farm near Santiago, inherited from his father.
In 1828 Dahlonega was the site of the first major gold rush in the United States. The Dahlonega Gold Museum Historic Site stands in the middle of the town square, housed in the 1836 Lumpkin County Courthouse. From its steps in 1849, Dahlonega Mint assayer Dr. M. F. Stephenson tried to persuade miners to stay in Dahlonega instead of joining the California Gold Rush, saying, "There's millions in it," often misquoted as "There's gold in them thar hills." Dahlonega is home to the main campus of the University of North Georgia.
Bishop was born on July 12, 1881, in Tokyo, Japan, where his parents were Methodist missionaries. He attended the English School in Tokyo from 1888 to 1897. In 1898 he entered the Northwestern Academy, Evanston, Illinois, then attended DePauw University, in Greencastle, Indiana, from 1901 to 1904; Hampden-Sydney College in Hampden-Sydney, Virginia, 1905–06; and Business College in Poughkeepsie, New York, from 1906 to 1907. Bishop developed his interest in anthropology and archaeology during 1907–12 when he traveled in the southwestern United States and Central America and was silver assayer in Mexico during the Yaqui Wars there in 1905–06.
Pitcher was born in London and became interested in fossils in childhood. At 17 he started work as an assistant assayer, attending college part-time to study for a degree in Chemistry and Geology at Chelsea College, London, graduating after war service in 1947. Professor Herbert Harold Read of Imperial College offered him a post as a Demonstrator with the opportunity to study granite rocks in Donegal, and Pitcher, with his wife Stella Scutt, started in 1948 a 25-year programme of rock mapping in Donegal. He was promoted to Assistant Lecturer (1948) and then to Lecturer (1950–1955).
Two former partners ("Andy Martin" and "Pete Menlo") from a previous mining claim are working in the strike town of "Goldfield", one running a saloon/ casino/ brothel (the "Fandango") and the other providing mining advice and management for the claims that the casino takes in as security against player's stakes. A regular gambler is "Jackpot" (whose daughter, Nevada, is the films love interest and the town's ore assayer). Buying up a mine stake, the partners make a rich strike. But their miners are taken away by a better pay offer from the town's other main mining magnate, "Bannon".
By 1897 he was BHP's representative in Western Australia, with temporary offices in Hannan Street, Kalgoorlie, offering to purchase gold- bearing ore of any description. That same year he was working as assayer for the Kalgurli mine on the Golden Mile, then in April 1900 was appointed general manager of that and the Hainault mine. In 1907 he resigned both positions (replaced by Archie Hay and Robert S. Black) to set up a tin dredging plant at Greenbushes, Western Australia, which he ran for 17 years. During this period he also managed the Sand Queen mine.
Originally from Elmira, New York, Fassett graduated from Elmira Free Academy, influenced by teacher Joel Dorman Steele to become a chemist. After briefly working as a pharmacist in Elmira, he moved west to Nevada at Reno, then at Eureka, working as a chemist, drug store owner, and assayer. Late in 1889, he relocated north to Spokane, Washington, and opened C. M. Fassett & Co, assayers and chemists, which became one of the most prominent of such businesses in the Inland Empire. Fassett also served as consultant to mining companies, including directing the building of the first cyanide leach gold mill in Korea in 1900.
This same shape has been maintained until the present. Archaeological investigations as well as archaeometallurgical analysis and written texts from the Renaissance have demonstrated the existence of different materials for their manufacture; they could be made also with mixtures of bones and wood ashes, of poor quality, or moulded with a mixture of this kind in the bottom with an upper layer of bone ashes.Martinón-Torres, M. and et al. 2009 Different recipes depend on the expertise of the assayer or on the special purpose for which it was made (assays for minting, jewelry, testing purity of recycled material or coins).
The controversy prompted William E. DuBois, Mint Assayer, to try, in 1860, to recall the examples of the 1804 dollar in private hands. According to DuBois, five coins were known to be privately owned, of which four were recovered. He stated that three were destroyed in his presence, and one was added to the Mint's coin cabinet (of which he was curator, and which is today the National Numismatic Collection), where it remains today. The coin, which is the sole known Class II specimen in existence, was struck over an 1857 Swiss shooting thaler minted for the federal shooting festival held in Bern.
Cesi managed to expand the ranks of the Academy, recruiting Giambattista della Porta himself in 1610 and Galileo Galilei in 1611. Cesi's letter to Galileo of 21/7/1612 mentioned Kepler's ellipses. Cesi's Academy published Galileo's Istoria e dimostrazione intorno alle macchie solari (Letters on Sunspots) in 1613, The Assayer in 1623, and also had a hand in defending Galileo in his controversies with establishment leaders and ecclesiastical authorities. Cesi's own intense activity in the Academy was cut short by his sudden death in 1630 and the original Accademia dei Lincei did not survive his death.
Crushing equipment was brought to the field from the Palmer and Etheridge and established at Tyrconnel Creek, Watsonville (also known as Woodsville), Beaconsfield, Kingston (later Kingsborough) and Thornborough. In total, 8 machines were operating on the Hodgkinson and within a year of its discovery settlements were located close to the major reefs, with Kingston and Thornborough the major settlements on the field. By mid 1877 Kingston (later Kingsborough) had a population of 1,100, with 8 general stores, 2 butchers, and 12 public houses. There was a lemonade factory, chemist, baker, auctioneer, assayer, blacksmith, newsagents, and brickworks as well as the Vulcan crushing battery.
After a year in Sulpher Springs Valley, where he cultivated strawberries, he moved to Bisbee at his father's request to work as an assayer for the Copper Queen Mine.Robert Paul Browder and Thomas G. Smith; Independent: A Biography of Lewis W. Douglas; Alfred A. Knopf Co.; New York; 1986; p. 10. In 1892 Douglas moved to Prescott to work for the Commercial Mining Company, an affiliate of the Phelps Dodge mining company. Eight years later he was transferred to Sonora, Mexico, to manage the copper mine and smelter at Pilares and Nacozari; and directed construction of a railroad from Douglas, Arizona to Nacozari.
New York: Alfred A. Knopf, 1928. (pg. 176-179) The victim was brought to an accomplice posing as an assayer, who occupied an office and displayed the necessary equipment, who confirmed Wadell's claims. If the person was still not convinced, Waddell would take out a slug of real gold and suggest he take that piece to a jewelers where, even if the victim took him up on his offer, he would be satisfied when it was correctly identified by the jeweler. Waddell sold his first brick for $4,000 and began manufacturing bricks which were sold for between $3,500 and $7,000.
Responding to the sudden surge of market needs of lead-free solder wire for copper pipes soldering in Hong Kong's construction industry, Lee Kee upgraded the production equipment and produced lead-free solder wire which was approved by Hong Kong Water Supplies Department and obtained Q-Mark certificate. In 2016, Promet Metals Testing Laboratory became an approved LME Listed Sampler and Assayer (LSA) for pure zinc, aluminium and aluminium alloys. In 2017, Lee Kee established LKG Singapore (Private) Limited to provide alloys and services to customers in Southeast Asia. In 2019, Lee Kee established LKG (Malaysia) SDN. BHD.
Robert Lucian Stanislaus Kaleski was the son of a Polish mining engineer, John Kaleski, and his English wife Isabel, née Falder. Political pressures in Poland led John Kaleski to move to Germany, where he held academic appointments at Bonn and Heidelberg Universities, and from there to Australia where he re-built a career as a mining engineer and assayer. Robert Kaleski was born on 19 January 1877 at Burwood in Sydney. Ill health as a child led to him spending long periods with a relative at Holsworthy, where he attended little school but learned much about the local bush.
In The Assayer he wrote "Philosophy is written in this grand book, the universe ... It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures;...." His mathematical analyses are a further development of a tradition employed by late scholastic natural philosophers, which Galileo learned when he studied philosophy.Wallace, William A. (1984) Galileo and His Sources: The Heritage of the Collegio Romano in Galileo's Science, Princeton: Princeton Univ. Pr. He ignored Aristotelianism. In broader terms, his work marked another step towards the eventual separation of science from both philosophy and religion; a major development in human thought.
A record of this meeting is found in a touching 2-page memo that summarizes the meeting and was presented to the family. It includes the passages, and it is signed by Superintendent A. Loudon Snowden, Assayer William E. DuBois, Melter & Refiner James E. Booth, and Coiner O.C. Bosbyshell, Following William's death, several of the assistant engravers wanted the top job, including Charles Barber, George Morgan, and others. After a number of months of deliberation, President Rutherford B. Hayes made the decision, and Charles Barber succeeded his father as Chief Engraver on January 20, 1880. Painting of William Barber, c.
The first women to be appointed to the Assay Commission were Mrs. Kellogg Fairbanks of Chicago and Mrs. B.B. Munford of Richmond, Virginia, both in 1920. The recordholder for service as a commissioner is Herbert Gray Torrey, 36 times an assay commissioner between 1874 and 1910 (missing only 1879) by virtue of his office as assayer of the New York Assay Office. The recordholder as a presidential appointee is Dr. James Lewis Howe, head of the Department of Chemistry at Washington and Lee University, 18 times an assay commissioner, serving in 1907 and then each year from 1910 to 1926.
The Principles of Political Economy, p. 4. In so doing, it expounded upon the "final" (marginal) utility theory of value. Jevons' work, along with similar discoveries made by Carl Menger in Vienna (1871) and by Léon Walras in Switzerland (1874), marked the opening of a new period in the history of economic thought. Jevons's contribution to the marginal revolution in economics in the late 19th century established his reputation as a leading political economist and logician of the time. Jevons broke off his studies of the natural sciences in London in 1854 to work as an assayer in Sydney, where he acquired an interest in political economy.
Ott's Assay Office is a historic assay office located at 130 Main Street in Nevada City, California. The building was constructed in 1851 as a drug store; James J. Ott opened his assay office in the back of the store in 1857. In 1859, Ott assayed a sample of silver ore discovered in the Washoe Country; this ore marked the discovery of the Comstock Lode, and the resulting silver rush eventually led to Nevada's statehood and several advancements in mining technology. The silver rush also gave Ott a reputation as a quality assayer; he ran his office until his death in 1907, and his son continued the business until 1955. .
The early dwelling, now substantially extended and altered, was built in 1701 by Reijnier Smedinga, silversmith, goldsmith, jeweller and joint assayer to the Dutch East India Company. In 1722, Anthonij Hoesemans, lessee of a Company's wine license, took ownership of the house and erf 8. His enjoyment of the property was brief, for in 1723 the minutes of the Council of Policy at the Cape of Good Hope begin to refer to Claas van Donselaar, a soldier who had been released from his contract on 4 May 1723, as the lessee of the wine license. Both Hoesemans and his wife, Rijkje van Donselaar, had died earlier that year.
Privately minted "silver rounds" or "generic silver rounds" are called "rounds" instead of "coins" because the US Mint and other government mints reserves the use of the word "coin" for Government Issued currency with a face value expressed in the national currency. The privately minted "rounds" usually have a set weight of 1 troy ounce of silver (31.103 grams of 99.9% silver), with the dimensions of 2.54 mm thick and 39 mm across. These carry all sorts of designs, from assayer/mine backed bullion to engravable gifts, automobiles, firearms, armed forces commemorative, and holidays. Unlike silver bullion coins, silver rounds carry no face value and are not considered legal tender.
Indeed, when Romford council began its Mawney Road housing development in July 1952, they offered Pilgrim only £65 for the lot - a value that was confirmed by the assayer. Pilgrim, however, did not even know of the offer (and purchase) by the government until the project began, and he did not appeal until February 1954, when construction on the site actually began. The Romford council had a housing waiting list of 1,600 people, and so it would not remove Mr. Pilgrim's lot from its scheme. They determined that he was merely an imprudent land speculator who had not bothered to inform himself of the legal issues surrounding his purchase.
Bob and Chito are two unemployed and down on their luck travelling wranglers who help an older man, Ben Jason, replace the broken wheel on his wagon in a desolate part of Arizona. For their generosity, they are given a gold nugget and an offer of "pick and shovel" work on Ben's place. Visiting Matt Wyatt, an assayer in the nearest town, Bob and Chito are told that the nugget is of such purity that it must be from the Lost Dutchman's Gold Mine, a long lost mine that became a legend due to its wealth. Chito reveals that Ben Jason gave them the nugget.
Arshtat's eschatological role is carried forward into the 9th–14th century texts of Zoroastrian tradition, where she appears as Middle Persian Ashtad. Arshtat is an assayer of deeds at the Chinvat bridge, the bridge of judgement that all souls must cross. in Bundahishn (37.10–14), Arshtat plays this role together with the Amesha Spenta Ameretat, of whom Arshtat is a hamkar "co-operator"; and in the Book of Arda Wiraz (5.3), she stands there with Mithra, Rashnu, Vayu-Vata, and Verethragna. In the apocalyptic Zand-i Wahman yasn (7.19-20), Arshtat—together with Nairyosangha, Mithra, Rashnu, Verethregna, Sraosha and a personified Khwarenah—assists the hero Peshyotan.
He began working for BHP at Broken Hill, becoming chief assayer, then worked as assistant metallurgist at their Port Pirie smelter. He returned to Broken Hill, where he spent a year working underground, then another year at the Victorian goldfields. He sailed to Albany, Western Australia in October 1893 with his brother Ned, and according to one report travelled on foot to Coolgardie (some 700km), where they worked the Coonega and Lady Margaret goldfields near Comet Vale, though the credit for their discovery may belong to their associate Dan Baker. He purchased the Sand Queen claim, from two of its finders, Tom Caldwell and Dick Delaney.
He was comptroller and assayer st the Southwark mint from 1547 to 1551, appointed commissioner for the new coinage in December 1550 and under treasurer at the Tower mint from 1560 to 1562. The profits from the appointments enabled him to buy land in both Buckinghamshire and Lancashire, particularly the estate known as the Vache in Chalfont St Giles, which he purchased in 1564. He was a Member (MP) of the Parliament of England for Preston in March 1553 and for Buckinghamshire in 1563 and was pricked High Sheriff of Bedfordshire and Buckinghamshire for 1564–65. He died in 1570 and was buried in an elaborate tomb at Chalfont St. Giles.
In 1623, Galileo Galilei wrote: > Philosophy [i.e. physics] is written in this grand book—I mean the > universe—which stands continually open to our gaze, but it cannot be > understood unless one first learns to comprehend the language and interpret > the characters in which it is written.

In 1942 during the Second World War, British wartime restrictions on the manufacture of jewelry resulted in "utility" wedding rings that were limited to a maximum mass of two pennyweights, being slightly heavier than 3 grams, and were forged of 9 carat gold rather than the traditional 22 carat. The Regional Assayer Office hallmarked these rings, which guaranteed their gold content and compliance with the wartime regulations with a special utility mark adjacent to the mark for the year on the inside of the band; the hallmark resembled a capital "U" with the bottom curve absent or two parentheses enclosing a space, i. e., "()".
Binder was an assayer and jeweller and probably already had an office on the site as the fee paid was nominal and probably simply covered the survey costs. In July 1889, Binder sold the property to David Lyall, who had been working in Charters Towers as a jeweller and watchmaker since at least 1886. His advertisements in the Northern Miner from the Mosman Street address stated that any article of jewellery could be made on the premises to a standard of workmanship equal to be best in London or Edinburgh. Lyall was developing his business at the height of Charters Towers importance as a gold field.
Spence was born in Bombay, India, the son of Urwin Archibald Spence, an assayer with the Royal Mint. He was educated at the John Connon School, operated by the Bombay Scottish Education Society, and was then sent back to Scotland to attend George Watson's College in Edinburgh from 1919–1925. He enrolled at Edinburgh College of Art (ECA) in 1925, studying architecture, where he secured a maintenance scholarship on the strength of the "unusual brilliance" of his work. He won several prizes at the college, and meanwhile carried out paid work drawing architectural perspectives for practising architects including Leslie Grahame-Thomson, Reginald Fairlie and Frank Mears.
Because the new manager, Joseph Cock, had yet to arrive in Nelson, a geological survey of the mines was conducted on 1 June 1864 by Dr James Hector, an assayer working for the Otago Provincial Government. On 5 July 1864 Cock and his family arrived in Nelson. The directors were disappointed when on examining the mines Cock came to the same conclusion that had already been conveyed to them regarding the chromite supplies. He set about prospecting other areas in the mineral belt in an attempt to find other workable lodes of chromite, including a deposit below the railway which would have required a branch line to be constructed.
Russell Johnson Parker was the first Mine Manager while Lewin Tucker took up a position of mine secretary in 1927. The chief assayer was Jerry Haynes who later worked as smelter superintendent at Mufulira Mine; and, among the geologists, Dr. Anton Grey, (chief geologist), Dr. David Donaldson, Jock Brown and Bill Garlick who was a replacement geologist for Dr. T.F. Andrews and a Mr. Heins who had drowned in Chibuluma. Others who worked at Chambishi Mines in 1927 include, Phil Melville who was chief surveyor while E. P. Edwards worked as mining engineer. George Hornby, a contractor in charge of pitting was one of the Europeans who arrived early at Chambishi.
While bullion coins can be easily weighed and measured against known values to confirm their veracity, most bars cannot, and gold buyers often have bars re- assayed. Larger bars also have a greater volume in which to create a partial forgery using a tungsten-filled cavity, which may not be revealed by an assay. Tungsten is ideal for this purpose because it is much less expensive than gold, but has the same density (19.3 g/cm³). Good delivery bars that are held within the London bullion market (LBMA) system each have a verifiable chain of custody, beginning with the refiner and assayer, and continuing through storage in LBMA recognized vaults.
Chiaramonti's second and more significant venture into this scholarly field came with his 1621 work Antitycho which opposed the argument of Tycho Brahe that comets were celestial bodies following an orbit above the Moon. In this work Chiaramonti tackled not only Tycho but Grassi, devoting 10 of the work's 65 chapters to refuting his arguments about comets. When Johannes Kepler received a copy of Antitycho, he replied with Shieldbearer for Tycho. Despite the fundamental difference of views with Chiaramonti, Galileo maintained cordial relations with him at this time, referring to him positively in The Assayer as having conclusively proved the falsity of Tycho's model of the universe.
In 1547, he was appointed as an assayer at the mint of Reggio by the council, eventually becoming the mint's manager (in 1552), and ultimately a spenditore (treasurer) to the council. In 1550 he travelled to the Duchy of Mantova to advocate the value of coins minted in Reggio - based on their gold content - against their devaluation in Mantova, which had been declared by a grida (fiat) of Cardinal Ercole Gonzaga. He continued to Parma, where he convinced the Duke, Ottavio Farnese, of the value of Reggio's currency without assay, but through logic and reason alone. In 1576 he likewise went as an ambassador to the Duchy of Ferrara.
Five years later, Kemple returned to the Silver Reef area, staked a few mining claims, and organized them under the Union Mining District. The Union Mining District was abandoned, but in 1874, Kemple returned with a group of miners, reorganized the claims under the Harrisburg Mining District, and began developing a mine. Kemple later became discouraged with his claims and sold them. According to a less accepted story, a man known as "Metalliferous" Murphy, an assayer from Pioche, Nevada, was brought a piece of a grindstone made of sandstone from the Silver Reef area by miners in Pioche. After performing tests on the sample, Murphy stated that it contained over $200 of silver per ton.
While working on the ranch, Kelly announced that he had discovered a gold mine, and was "greeted only with jeers". The next day he again tried to tell the Reagans about the mine, even going so far as to show them a lump of gold ore, but received a "cussing out" for his trouble. After this rejection, Kelly went to San Antonio, where he knew a white assayer, and asked him to analyze the ore. Stories then conflict: One account states that he returned to Dryden, where the Reagans received a letter addressed to him that confirmed the gold was immensely valuable, and then killed him and dumped his body in the Rio Grande.
From 1853 he was chief assayer to the United States assay office in New York City when that office was established, but he continued to take an interest in botanical teaching until his death. He was frequently consulted by the treasury department on matters pertaining to the coinage and currency, and was sent on special missions at various times to visit the different mints. He was elected an Associate Fellow of the American Academy of Arts and Sciences in 1856. In 1856, Torrey was chosen a trustee of Columbia College, and in 1860, having presented the college with his herbarium, numbering about 50,000 specimens, he was made emeritus professor of chemistry and botany.
A Daughters of the American Revolution historic marker for the fort near Minnesota State Highway 66 Fort L'Huillier (sometimes spelled Le Hillier) was a short-lived fortification in New France located near the confluence of the Blue Earth and Le Sueur Rivers in what is now Minnesota. The garrison, which originally held about 30 men, was built beginning in the autumn of 1700 under the direction of Pierre-Charles Le Sueur, a French trader and explorer interested in mining a blue clay that he thought was copper ore. It was named in honor of a metallurgical assayer, Remy-François L'Hullier. Le Sueur left the fort in 1701 to take samples to New Orleans for further analysis.
He also played a valuable role for Galileo, ensuring that he was kept up to date with developments in the Curia and on the reception of his most recent work, The Assayer. In the summer of 1624 he informed Galileo of his meeting with Orazio Grassi and of the apparently positive comments Grassi had made about Copernican theory. Later, he warned Galileo about two strongly-worded attacks from the Jesuit order on those who sought to overthrow the Aristotelian worldview. Guiducci was also the intermediary through whom Galileo communicated to his colleagues in the Accademia dei Lincei the manuscript of his response to Francesco Ingoli's 1616 letter challenging Copernican ideas, De situ et quiete Terrae contra Copernici systema Disputatio.
This state of affairs was unsatisfactory to the director, Samuel Moore, who had for several years contemplated purchasing a modern set of steam machinery for the production of coins from the Soho Mint in Birmingham, England, founded by coining pioneer Matthew Boulton. Moore instead decided to engage a new employee and send him on a special tour of European mints and refineries, in order to learn the best features of each and bring the knowledge home for use at the Philadelphia facility. The individual would be given the title of Assistant to the Assayer, Jacob R. Eckfeldt. Moore obtained the approval of Treasury Secretary Louis McLane and an appropriation of $7,000 for the purpose.
Power was born in England, a son of Samuel Browning Power (1824–1892), a shipowner of London, and his wife Rebecca Danvers (1835–1902). He was educated at Malvern College, the Royal School of Mines, London, and the Mining Academy, Clausthal, Germany.Clausthal was also home of German-Australian geologists H. W. F. Kayser and G. H. F. Ulrich In 1884 he migrated to Australia, settling in Melbourne. He worked in an assay laboratory in Bethanga until 1887, While assayer for the Union Bank, he was in 1890 a key witness in the trial of Robert J. W. Pound, accused of the theft of some £5,000 worth of platinum from the Otway Ranges Company.
Jules Speller, Galileo's Inquisition Trial Revisited, Peter Lang, 2008 p.114 He followed this up with another letter on 2 December 1623 reporting Orazio Grassi's reaction to the publication of The Assayer and his promise to respond to it quickly. He also reported that Urban VIII had read it and was very pleased with it.Jules Speller, Galileo's Inquisition Trial Revisited, Peter Lang, 2008 p.115 On 10 August 1624 Rinuccini wrote that Grassi had visited Galileo's friend visit Mario Guiducci while he was sick.Jules Speller, Galileo's Inquisition Trial Revisited, Peter Lang, 2008 pp.116 It appears that behind a show of friendliness Grassi was gathering information to denounce Galileo to the Roman Inquisition.
He joined the Metals Extraction Company, and was sent to Broken Hill with metallurgist Askin Nicholas to troubleshoot one of Junction North mine's processes. In 1894 he joined Broken Hill's Block 10 Company as assayer, then in October 1896 joined "The Proprietary" (BHP). Around this time he began experimenting with ways of converting refractory zinc sulphide to the oxide. In 1901 he worked with Leslie Bradford in developing the Carmichael–Bradford desulphurisation process for conversion of sulphide ores to their oxides prior to smelting, which enabled recovery of valuable metal from the great piles of tailings at the mines, and the manufacture of sulphuric acid, leading to the founding of the Zinc Corporation.
In 1891, aged 23, he submitted his first paper to the Cornwall Polytechnic Society, followed by several more, earning him various medals in recognition of his industry. In 1899, Davey met ornithologist and plant collector A. O. Hume, C.B., founder of the South London Botanical Institute, who was to accompany him on tours of Devon and Cornwall. This was clearly a seminal event, which led to Davey beginning his major opus, Flora of Cornwall, for which he was to become renowned. In 1900, Davey began training as a chemist and assayer at the Redruth School of Mines, and two years later succeeded his father as Works Manager of the Cornwall Arsenic Company's factory at Bissoe, having acted as his father's assistant for several years.
Thus, a limited amount of mathematics had long related music and physical science, and young Galileo could see his own father's observations expand on that tradition. Galileo was one of the first modern thinkers to clearly state that the laws of nature are mathematical. In The Assayer, he wrote "Philosophy is written in this grand book, the universe ... It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures;...." His mathematical analyses are a further development of a tradition employed by late scholastic natural philosophers, which Galileo learned when he studied philosophy. His work marked another step towards the eventual separation of science from both philosophy and religion; a major development in human thought.
He also wanted additional mechanization in the mint's Coining Department, headed by Chief Coiner Adam Eckfeldt, whose son Jacob was the Philadelphia Mint's Assayer. Adam Eckfeldt had helped strike some of the first federal coins in 1792 and had been in his office since 1814. Eckfeldt was reluctant to adopt all Peale's recommendations, telling Peale's nephew, engineer George Sellers, "If Mr. Peale had full swing he would turn everything upside down ... he wants something better and no doubt he would have it if we were starting anew." As improvements crept in despite Eckfeldt's caution, the Chief Coiner saw their value and became more enthusiastic, noting the savings in working time afforded by the Contamin lathe, which had been imported from France after being seen by Peale there.
From 1899 to 1929 he worked as metallurgist and General Manager at the Golden Horseshoe Estates, Ltd mine, producing between £300,000 and £400,000 worth of gold annually. Sutherland lost that job in 1929 when the leases passed to Lake View and Star, Ltd, and the huge tailings dump was taken over by Golden Horse Shoe (New), Ltd. He worked as a consulting mining engineer in Perth from 1929 to 1938, then from 1938 to 1946 was assayer for the Phoenix Gold Mine in Coolgardie. Sutherland, like captains Hancock, Warren and Greenway at Moonta and Broken Hill, addressed the "sulphide problem", refractory ores such as galena (zinc sulphide) that unlike the associated silver and lead compounds, resisted reduction to the base metal by roasting.
The gold stamping mill was built in 1850-51 by Moffat and Company, operating under the authority of Augustus Humbert, who had been appointed by President John Tyler to be the federal assayer for the new state of California. The Mount Ophir Mint produced Octagonal Gold Slugs with a fifty-dollar denomination. On February 14, 1851 the newspaper, the San Francisco Prices Current, indicated that the production of $50 slugs was about to begin: > The above cut represents the obverse of the United States ingot, or, rather, > coin, of the value of $50, about to be issued at the Government Assay > Office. It is precisely of this size and shape.... The reverse side bears an > impression of rayed work without any inscription.
The Rillito School Board proposed a site for a school, but a number of settlers asserted that the proposed location was as undesirable as the Congress Street School. These settlers resided on the eastern edge of the Rillito School District and eventually petitioned the Pima County Board of Supervisors to establish an independent school district. On July 3, 1893, Amphitheater Public Schools became a reality. According to Amphitheater High School graduate and historical writer for the Arizona Daily Star newspaper, David Leighton, the founding board members were rancher and assayer Edward L. Wetmore (the Wetmore family is the namesake of Wetmore Road in North Tucson), homesteader and carpenter Levi Marston Prince (namesake of Prince Road in North Tucson), and rancher Joseph D. Andrews.
He acted as the city's assayer from 1539. Zürich issued a thaler coin minted by Stampfer, the so-called Stampfertaler, during 1555-1560. Arnold Luschin von Ebengreuth, Heinrich Buchenau, Grundriss der Münzkunde (1920), p. 84. He married Margaretha von Schönau (d. 1555). He was reeve of Wädenswil during 1570 to 1577. At least 26 distinct medals by Stampfer are known, not including his production of coins for circulation, made during the period of 1531 to 1566. Most of his medals bear the monogram I·S. His most famous works are the Bundestaler (1546), with an early representation of the Three Confederates, and one of the earliest representations of the coats of arms of the Thirteen Cantons and of the Swiss cross, and the Patenpfennig for Princess Claude (1547).
In Il Saggiatore (The Assayer) (1623) Galileo was mostly concerned with faults in Orazio Grassi's arguments about comets, but in the introductory section he wrote : > 'How many men attacked my Letters on Sunspots, and under what disguises! The > material contained therein ought to have opened to the minds eye much room > for admirable speculation; instead it met with scorn and derision. Many > people disbelieved it or failed to appreciate it. Others, not wanting to > agree with my ideas, advanced ridiculous and impossible opinions against me; > and some, overwhelmed and convinced by my arguments, attempted to rob me of > that glory which was mine, pretending not to have seen my writings and > trying to represent themselves as the original discoverers of these > impressive marvels.
The hearing continued and Capra's position was further weakened when he refused to demonstrate to the tribunal how the compass was used. The rectors found him guilty and ordered that all copies of his book were to be destroyed, though some had already been sent outside the Republic of Venice. Galileo published their verdict in his favour, as well as a tract entitled Difesa contro alle calunnie et imposture di Baldessar Capra (Venice, 1607), which showed how Capra's accusations were false. Galileo apparently believed that it had been Simon Mayr who had instigated Capra's false claim, and in his great work The Assayer he accused Mayr of having translated his instructions on the compass into Latin and then having them printed using Capra's name.
Robert Kay was born in Newcastle on Tyne and educated at the Grammar School in that town then went to work as accountant at the iron works of which his father was manager and part owner. At the age of 24 he inherited his father's share of the business, which he sold and left for Australia on the Ascendant, arriving in South Australia in January 1851. He worked for a time as gold assayer before trying his luck on the gold fields of Mount Alexander, but soon returned to the Assay Office, where he was employed making gold tokens which at that time were used as currency. In 1853 he married and took up a farm in Woodside, and was soon elected to the Onkaparinga district council and served for a time as chairman.
The contributions that Galileo made to observational astronomy include the telescopic confirmation of the phases of Venus; his discovery, in 1609, of Jupiter's four largest moons (subsequently given the collective name of the "Galilean moons"); and the observation and analysis of sunspots. Galileo also pursued applied science and technology, inventing, among other instruments, a military compass. His discovery of the Jovian moons was published in 1610 and enabled him to obtain the position of mathematician and philosopher to the Medici court. As such, he was expected to engage in debates with philosophers in the Aristotelian tradition and received a large audience for his own publications such as the Discourses and Mathematical Demonstrations Concerning Two New Sciences (published abroad following his arrest for the publication of Dialogue Concerning the Two Chief World Systems) and The Assayer.
Mint Assayer William DuBois wrote to Longacre, "it is truly pleasing to see a man pass the life of three score and ten and yet be able to produce the same artistic works as in earlier days." In 1865 Congress required the use of "In God We Trust" on all coins large enough to bear the inscription; in 1866, Longacre added the motto to all silver coins larger than the dime and all gold coins larger than the three-dollar piece. He also in 1867 made modifications to the design of the copper-nickel five-cent piece, or nickel as it was coming to be known. In 1865, Longacre engaged British-born engraver William Barber as assistant; William H. Key was also made an assistant in 1864 and remained at the Mint past Longacre's death.
He next became a partner with bankers Samuel J. Hensley and Robert D. Merrill in April 1850 and was their agent for two months. He went back to Washington briefly, then returned to San Francisco in January 1851 on the steamer Tennessee, along with Augustus Humbert, who had been appointed to be U.S. assayer in San Francisco. In that year King established another company, and it was there that his firm struck $20 gold ingots. Coin historian Donald H. Kagin has written that, in March 1851, "the most notorious chapter in private gold coinage occurred", when King sent $180 in face value of coins minted by a number of entrepreneurs to Humbert, who reported after assaying them that the samples were worth 1.8 percent to 3 percent under market value.
Michael Lok said that Frobisher, upon his return to London from the Arctic, had given him the black stone as the first object taken from the new land. Lok brought samples of the stone to the royal assayer in the Tower of London and two other expert assayers, all of whom declared that it was worthless, saying that it was marcasite and contained no gold. Lok then took the "ore" to an Italian alchemist living in London, Giovanni Battista Agnello, who claimed it was gold-bearing. Agnello assayed the ore three times and showed Lok small amounts of gold dust; when he was challenged as to why the other assayers failed to find gold in their specimens, Agnello replied, "Bisogna sapere adulare la natura" ("One must know how to flatter nature").
Peale wrote that he "cannot speak in too high terms of Mr. Percival Johnson ... I have derived much useful information in his refinery particularly his method of separating silver, gold and paladium [palladium] by a shortened process". While in London, Peale ordered a delicate balance scale from his friend, expatriate American Joseph Saxton, and later induced Saxton to return to the United States and work for the Philadelphia Mint. Peale returned to France where, as the refiners wanted payment for teaching him the French method of parting, he learned it by observing the assayer at the branch mint in Rouen. He was not completely happy with this, as he was not allowed to practice it himself, or to experiment, but felt that he could reproduce what he had seen on his return to Philadelphia.
Precious metal items of art or jewelry are frequently hallmarked (depending upon the requirements of the laws of either the place of manufacture or the place of import). Where required to be hallmarked, semi-finished precious metal items of art or jewelry pass through the official testing channels where they are analyzed or assayed for precious metal content. While different nations permit a variety of legally acceptable finenesses, the assayer is actually testing to determine that the fineness of the product conforms with the statement or claim of fineness that the maker has claimed (usually by stamping a number such as 750 for 18k gold) on the item. In the past the assay was conducted by using the touchstone method but currently (most often) it is done using X-ray Fluorescence (XRF).
But the Old Guard Republicans in Idaho opposed him and they were determined to defeat Borah in his second bid for the Senate. The same year, Dubois damaged his prospects for a third term by his opposition to the appointment of H. Smith Woolley, a member of The Church of Jesus Christ of Latter-day Saints (many Idahoans adhered to that faith), as assayer-in-charge of the United States Assay Office at Boise. Dubois had advanced politically through anti- Mormonism in the 1880s, but the issue was more or less dead in Idaho by 1904. Woolley was confirmed by the U.S. Senate despite Dubois's opposition, and Rufus G. Cook, in his article on the affair, suggested that Dubois was baited into acting by Borah and his supporters.
It has been suggested that Grassi was the author of an anonymous complaint to the Inquisition soon after Il Saggiatore appeared, asserting that the book advanced an atomic theory of matter, and that this conflicted with the Catholic doctrine of the Eucharist, because atomism would make transubstantiation impossible. Although most scholars do not agree that Grassi was its author, it is noteworthy that his second response to Il Saggiatore, the Ratio ponderum librae et simbellae (1626), contains many of the same arguments as the anonymous complaint. While Libra had focused on mainly astronomical issues, Ratio focused on doctrinal issues. :... unlike The Assayer, which had recourse to the lethal polemical weapons of satire and the new philosophy, the Ratio used those no-less-lethal weapons of doctrinal and dialectical retort based on religious and philosophical orthodoxy.
He was assistant professor of chemistry in the New Hampshire medical college, 1826–28, and an expert chemist in Boston, Mass. , 1828-82. He was the discoverer of the organic alkaloid sanguinaria; invented in 1838 a novel arrangement of steam boilers for the economical generation of steam: and first suggested the application of oxides of iron in refining pig-iron ; and a process for the production of saltpetre from sodium nitrate by the action of potassium hydroxide. He was state assayer of Massachusetts and author of papers on The Cause of the Color of Lake Leman, Geneva ; The Bed Oxide of Zinc in New Jersey, and technical papers contributed to the Proceedings of various scientific societies of which he was a member and to the American Journal of Science.
Although time consuming, the method is the accepted standard applied for valuing gold ore as well as gold and silver bullion at major refineries and gold mining companies. In the case of fire assaying of gold and platinum ores, the lengthy time required to carry out an assay is generally offset by carrying out large numbers of assays simultaneously, and a typical laboratory will be equipped with several fusion and cupellation furnaces, each capable of taking multiple samples, so that several hundred analyses per day can be carried out. The principal advantage of fire assay is that large samples can be used, and these increase the accuracy in analyzing low-yield ores in the <1g/T range of concentration. 1916 photograph of an assayer performing an electrolysis test on a gold sample at the United States Assay Office in New York.
Arthur Launcelot Collins (8 July 1868 – 22 November 1902) was a British metallurgist, mining engineer and mine manager of properties in Mexico and the United States. He was born 8 July 1868 in Truro, Cornwall, England, the son of a prominent mining expert, Joseph Henry Collins, and brother of Henry, George, and Edgar Collins and William Collins, the Bishop of Gibraltar. Joseph H. Collins founded, and with his sons Henry, Arthur, and George, operated J. H. Collins & Sons, Mining and Metallurgical Engineers, an international mining consulting business headquartered in London, England. When he was 15 years of age, Arthur Collins traveled with his father and brothers Henry and George to Andalusia, Spain, in the great mining region of Rio Tinto, where Joseph Collins was appointed chief chemist and assayer of the Peña del Hierro copper mine.
He was born in Lambeth, London, the second son, by his second wife, of Charles Field, of the firm of J. C. & J. Field, candle manufacturers, etc. Educated at Denmark Hill grammar school and at Mr. Long's school at Stockwell (where he was a schoolfellow of Professor Odling), Field showed so strong a liking for chemistry that, on leaving school in 1843, he was placed in the laboratory of the Polytechnic Institution, then conducted by Dr. Ryan. On leaving the Polytechnic, Field entered into partnership with a chemist named Mitchell as an assayer and consulting chemist, but finding the need of further training spent some time as a student under Dr. Hoffmann in the Royal College of Chemistry in Oxford Street. Field was one of the original members of the Chemical Society of London, started in 1846, and he read his first paper to that society in the following year.
Thomas Barger was born in Minneapolis, Minnesota in 1909 to Mary Barger and Michael Thomas Barger. He grew up in Linton, North Dakota and graduated from the University of North Dakota's College of Engineering in Grand Forks, North Dakota with a degree in mining and metallurgy in 1931. After college he worked as a surveyor and miner in Canada, an engineer, assayer, and assistant manager of a silver and radium mine in the Northwest Territories and as an assistant professor of mining at the University of North Dakota. He accepted a position at the Anaconda Copper Mining Company but the Great Depression and falling copper prices resulted in his being forced to find work elsewhere. In 1937 Barger interviewed with J.O. Nomland, the chief geologist at the Standard Oil Company of California, in San Francisco and accepted a job as a surveyor in Saudi Arabia.
After graduation, Hyde went to work for the California State Mining Bureau as curator of its museum and as field engineer. This was followed with three years, 1903 -1906, as professor and head of the University of Oregon, Eugene's mining department where he helped found the new department. Offered a job in industry, he left the university in the fall of 1906, and spent the next three years during a mining boom that went bust with the Panic of 1907: he was metallurgist for a silver mill in Guanajuato, Mexico, 1906-1907; then an assayer for the Charles Butters & Company's cyanide plant at Virginia City, Nevada, 1907; then, 1907-1908, superintendent of a small stamp mill and attached cyanide plant at the short-lived gold rush town of Manhattan, Nevada; and then managed a gold prospect in the California Mother Lode country. He returned to education in 1909 as director of the San Diego public school system's new agriculture and horticulture program.
Some of history's greatest thinkers have pondered the mysteries of the tickle response, including Plato, Francis Bacon, Galileo Galilei and Charles Darwin. In The Assayer, Galileo philosophically examines tickling in the context of how we perceive reality: > When touched upon the soles of the feet, for example, it feels in addition > to the common sensation of touch a sensation on which we have imposed a > special name, "tickling." This sensation belongs to us and not to the > hand... A piece of paper or a feather drawn lightly over any part of our > bodies performs intrinsically the same operations of moving and touching, > but by touching the eye, the nose, or the upper lip it excites in us an > almost intolerable titillation, even though elsewhere it is scarcely felt. > This titillation belongs entirely to us and not to the feather; if the live > and sensitive body were removed it would remain no more than a mere word.
It is possible that a serious injury to his foot in his early childhood, which prevented him from taking part in the bustle of childhood activity, contributed to his independence and self-containment, and to an increasing interest in botany. However, it is documented that his father, Joe Morris, was an "enthusiastic" botanist and young Albert was his "offsider", so this was a more likely source of his botanical interests, as well as innate talent and an interest in the subject."Comments of readers: Appreciation of Late Mr A Morris" in "Barrier Miner" 14/01/39 By the time he was undertaking technical school studies in metallurgy and assaying, Morris had developed a small garden and nursery, and contributed to the cost of his fees by selling plants (pepper trees) that he had grown. Morris took up work with the Central Mine at Broken Hill, eventually becoming chief assayer for this mining company.
In his astronomical works, Liceti attempted to defend Aristotelian cosmology and geocentrism against the new ideas of heliocentrism proposed by Galileo and his followers. With the appearance of the famous comets of 1618 (which later gave rise to Galileo's work The Assayer), Liceti published a series of works arguing the Aristotelian view that comets occurred in the sphere of the upper heaves. These works included De novis astris, et cometis libri sex (1623), Controversiae de cometarum quiete, loco boreali sine occasu, parallaxi Aristotelea, sede caelesti, et exacta theoria peripatetica (1625), Ad ingenuum lectorem scholium Camelo Bulla (published as an appendix to his 1627 work De intellectu agente), De regulari motu minimaque parallaxi cometarum coelestium disputationes (1640), and De Terra unico centro motus singularum caeli particularum disputationes (also 1640). Liceti used these studies primarily to attack the views of G. C. Gloriosi (who had succeeded Galileo as chair of mathematics at the University of Padua) and Scipione Chiaramonti, both of whom published their own scathing counter-attacks on Liceti's views.
Their son Homer, Pound's father, worked for Thaddeus in the lumber business until Thaddeus secured him the appointment as registrar of the Hailey land office.Kavka (1991), 145–148; Moody (2007), 4 Homer and Isabel married the following year, in 1884. Pound in his Cheltenham Military Academy uniform, with his mother in 1898 Isabel Pound was unhappy in Hailey and took Ezra with her to New York in 1887 when he was 18 months old.Cockram (2005), 239; Moody (2007), 4 Her husband followed them, and in 1889 he found a job as an assayer at the Philadelphia Mint. The family moved to Jenkintown, Pennsylvania, and in 1893 bought a six-bedroom house at 166 Fernbrook Avenue, Wyncote. Pound's education began in dame schools: Miss Elliott's school in Jenkintown in 1892 and the Heathcock family's Chelten Hills School in Wyncote in 1893. Known as "Ra Pound" (pronounced "Ray"), he attended Wyncote Public School from September 1894.Carpenter (1988), 26–27 His first publication was on 7 November 1896 in the Jenkintown Times-Chronicle ("by E. L. Pound, Wyncote, aged 11 years"), a limerick about William Jennings Bryan, who had just lost the 1896 presidential election.
William R.Shea & Mariano Artigas, Galileo in Rome, Oxford University Press, 2003, p.96-98 Galileo was in frequent correspondence with a number of them, including Mario Guiducci, Francesco Stelluti and Benedetto Castelli, as well as both Rinuccini brothers. The new Pope was friendly towards Galileo and many of his ideas, and his election seemed an excellent opportunity to take a more assertive line on astronomy than had been possible since the Roman Inquisition had proscribed heliocentrism in 1616.William R.Shea & Mariano Artigas, Galileo in Rome, Oxford University Press, 2003, p.104 It was important for Galileo to carefully judge the political mood in Rome before publishing anything controversial and Tommaso Rinuccini was an important informant on whom he relied.Pietro Redondi, Galileo Heretic, Princeton University Press, 1987 pp.138, 181 The same year as the Pope was elected, Galileo published The Assayer, the final round in his protracted polemical battle with Orazio Grassi over the origin of comets, which Galileo mistakenly believed were an optical illusion. In a letter to Galileo on 20 October 1623, Tommaso Rinuccini wrote on behalf of Cardinal Barberini that Urban VIII had indicated he would appreciate a visit from Galileo.
John Macdonald Cameron (8 April 1847 – 3 September 1912) was a Scottish chemist and Liberal Party politician who sat in the House of Commons from 1885 to 1892. Cameron was the only son of Lachlan Cameron of Saltburn Ross and his wife Christina Macdonald of Brackla, Nairnshire. He was educated at Sharp's Institution, Perth and entered the Inland Revenue in 1866. In 1870 he gained a Board of Inland Revenue scholarship in Science and studied at the Royal School of Mines winning 1st class prize in Organic and Inorganic Chemistry. He was a chemist in the Inland Revenue Laboratory at Somerset House from 1870 to 1874 and then became an instructor in the Chemical Research Laboratory at the Royal School of Mines. In 1879 he began in business as an assayer and mining expert.Debretts Guide to the House of Commons 1886 He contributed to a geological paper on a possible new mineral from Scotland in 1880.Quarterly Journal of the Geological Society, 36, 109-111 (Jan. 1880) His reports on minerals include: from India, "Quartz outcrops of Travancore Lower India"; from Mexico, "The copper, silver-lead, and gold lodes of Huacaivo in the state of Chihuahua, republic of Mexico (1883)"; and, from Brazil, "The Bituminous Deposits of Camamu Basin, Bahia, Brazil".
