Page 4 - ... the author, as well as the principal results of their application to the minerals then known. This treatise did not appear till 1770, and was translated and published in Swedish by Retzius in 1773. It attracted the general attention of chemists and mineralogists to the use of this instrument. They, however, derived at first little other advantage from it than as a means of ascertaining the fusibility of bodies, and occasionally their solubility in borax ; for it was difficult to form a just estimate...
Page 405 - The most minute details are described with great accuracy, and the illustrations are so well executed, and so numerous, that a cursory inspection of the work is sufficient to convince the reader of its great practical utility. It is a kind of work for which there has long been a great demand in this country. Comprising a very complete account of all pharmaceutical operations, with the various modes of conducting them, as well as the apparatus.
Page 5 - ... means, which had escaped the most careful analysis, conducted by the ablest chemists of those times. Gahn was indefatigable in his observations and experiments with the Blowpipe, without which he never travelled; and though he was led to contrive several improvements in its application, which were imagined and executed with such sagacity and precision that his results were entitled to the greatest confidence, — he appears never to have thought of publishing an account of his labours, which...
Page 178 - There are several other native copper mines here that are equally promising, and will produce well when wrought with proper energy and skill. Copper Falls mine is an example, and is doing well. The northwest is another full of promise, and I have seen others which look very rich, but which are not yet opened deep enough to exhibit their contents. The shafts at the Cliff mine are 205 feet deep, and the hill above...
Page 35 - ... parts of chloride of ammonium. Chloride of sodium separates, and the liquid, when filtered and evaporated, affords the salt in fine crystals. When this salt is heated upon charcoal, or platinum wire, it loses its water and ammonia, and is converted into metaphosphate of soda, which, in consequence of its excess of acid, has the power of fusing almost every chemical compound. This salt, in the liquid state, detects magnesia and the protoxide of manganese. Besides the three reagents described,...
Page vii - Dr. Sheridan Muspratt's Translation of Planner's excellent Treatise upon the use and application of the Blow-Pipe, has been executed with fidelity and ability, and I consider its publication in England of essential service. The translated edition is further enhanced by Dr. Muspratt's annotations.
Page 5 - Columbium, then recently discovered, and of which he sent him a small specimen, Gahn immediately found that it contained tin, although that metal does not exceed one per cent. Long before the question was started, whether the ashes of vegetables contain copper, I have seen him many times extract, with the blow-pipe, from a quarter of a sheet of burnt paper, distinct particles of metallic copper.
Page 177 - ... can dissolve. By this process, the protoxide of uranium is converted into sesquioxide, which unites with the nitric acid, almost to the total exclusion of the iron. A current of...
