Elements Of Mineralogy Vol 1 Of 2 PDF Download

Excerpt from Outlines of Mineralogy, Geology, and Mineral Analysis, Vol. 1 of 2 The work which I now offer to the public, is the result of a laborious investigation which has occupied almost the whole of my spare time during a period of about ten years. The object in view, was to ascertain the chemical constitution of the different minerals which occur on the surface of the globe. For this purpose, I subjected to a rigid analysis every species that I could procure, except those which had been already investigated with sufficient accuracy by other chemists. During the course of this investigation, I analyzed several hundred specimens, and at least as many more were subjected to analysis by the numerous pupils who attended my laboratory, not a few of whom acquired great dexterity and accuracy in analysis, and have already, or speedily will distinguish themselves as analytical chemists. During these investigations, I met with a considerable number of new species hitherto overlooked by mineralogists, chiefly in specimens from Ireland, North America, and the West of Scotland, These new species, amounting to nearly 50, will be found described in the first volume of this work. Every true mineral species is a chemical compound, the constituents of which are united in definite proportions, and the greater number of them consist but of a very few ingredients. What makes it difficult or impossible to determine these ingredients with the requisite accuracy, is, that very few minerals are free from a mixture of foreign matter interspersed among their particles.
