Brownrigg

William Brownrigg (1711-1800) gave the first scientific description, which was revealed in 1750. [Pg.74]

Platinum - the atomic number is 78 and the chemical symbol is Pt. The name derives from the Spanish platina for silver . In 1735, the Spanish mathematician Don Antonio de Ulloa found platinum in Peru, South America. In 1741, the English metallurgist Charles Wood foimd platinum from Columbia, South America. In 1750, the English physician William Brownrigg prepared purified platinum metal. [Pg.16]

Although fire damp/ which is mainly methane, and choke damp (carbon dioxide) are frequent causes of mine accidents, Dr. William Brownrigg learned how to make good use of them. In 1741 he communicated to the Royal Society several papers on the gases of coal mines, but preferred to withhold them from publication until he could prepare a comprehensive treatise on the subject. His laboratory at Whitehaven was provided with several gas furnaces of his own design and a constant supply of fire damp from the nearby mines. Because of his skill in foretelling explosions by the rapid fall of the barometer, mine operators often consulted him. [Pg.83]

He also showed that many mineral waters contain considerable quantities of air identical with choke damp. Even at this early date he recognized the acidic nature of carbon dioxide and showed that some of the earths which had been precipitated from the water could be redissolved by the choke damp. He showed that, although the air from fermenting liquors. .. is. .. a deadly poison when applied to the lungs. . . exactly in the manner of the choak-damp,. . . yet nevertheless this air, when taken inwardly in a convenient quantity of a. liquid vehicle, is found to have wonderfully exciting and reviving qualities. . (S4). For his experiments on choke damp and carbon dioxide Dr. Brownrigg was awarded the Copley Medal. [Pg.83]

The earliest scientific descriptions of platinum, are those of Dr. Brownrigg and Don Antonio de UUoa in the middle of the eighteenth century. Rhodium, palladium, osmium, and iridium were discovered in 1803 and 1804, the first two by Dr. Wollaston and the others by his friend, Smithson Tennant. Thomsons History of Chemistry and Berzelius correspondence and diary present a pleasing picture of these two great English chemists. Ruthenium, the Russian member of the platinum family, was discovered much later by Karl Karlovich Klaus, whose life story was beautifully told by Professor B. N Menschutkin of the Polytechnic Institute of Leningrad. [Pg.407]

Charles Wood, a metallurgist and assayer, found in Jamaica some platinum from Cartagena [Colombia], and in 1741 took some of it to his relative, Dr. Brownrigg, After preparing a thorough and accurate description of the metal and its properties, Dr. Brownrigg in 1750 presented these specimens to the Royal Society of London. The exhibit included the ore as found in Nature, the purified metal, the fused metal, and a sword with a pummel made partly of platinum (2). [Pg.409]

About two years after the log of de Ulloa s voyage had been published, Sir William Watson and Dr. William Brownrigg contributed to the Philosophical Transactions a more detailed description of platinum. William Brownrigg was bom at High Close Hall, Cumberland, on March 24, 1711. He studied medicine in London and later in Leyden under H. Boerhaave, B. S. Albums, and W. J. s Gravesande, and began to practise in Whitehaven (2,63,64). [Pg.412]

A paper read by Watson before the Royal Society on December 13, 1750, contained an excerpt from a letter, dated Whitehaven, December 5th of the same year, in which Dr. Brownrigg had mentioned some experiments which a friend of his had made on the semi-metal called Platina di Pinto (sic ), a substance which he had not found mentioned... [Pg.412]

He added that this platina had been presented to him about nine years before by a skilful and inquisitive metallurgist [Mr. Charles Wood] who met with it in Jamaica, whither it had been brought from Carthagena (Colombia). Dr. Brownrigg believed it probable that there is great plenty of this semimetal in the Spanish West Indies, since trinkets made of it are there very common. He mentioned its high melting point and its refractoriness toward borax and other saline fluxes. But the Span-... [Pg.413]

When the British fisheries lacked an adequate supply of pure salt, Dr. William Brownrigg published an important book On the Art of Making Common Salt, which was condensed by Sir William Watson and published in 1848 in the Philosophical Transactions (36). [Pg.462]

With the advent of computerized systems and readily available hardware, total luminescence is gaining adherents. Brownrigg and Hornig (63) and Hornig and Giering (64) have reported on the low-temperature total luminescence applied to weather oils. Warner et al. (65) at the University of Washington applied sophisticated pattern recognition techniques to resolve a model mixture of nine petroleum-type polynuclear aromatic compounds from the complex total luminescence emission-excitation matrix (EEM). [Pg.78]

Mayow did not have the means to capture, manipulate, and study gases. These techniques awaited development hy Stephen Hales in 1727 and subsequent improvements by William Brownrigg, Joseph Black, Henry Cavendish, and Joseph Priestley. [Pg.220]

Until 1756, the only known gas or air was indeed common air. In that year. Dr. Joseph Black published his paper on the isolation and properties of fixed air (carbon dioxide or C02). He had used the pneumatic techniques of Stephen Hales and William Brownrigg to capture the air that was fixed in chalk (CaC03). Although Van Helmont had worked with this air over 100 years earlier, neither he nor other contemporaries truly characterized it. [Pg.266]
