Excerpt from Determinative Mineralogy: With Tables for the Determination of Minerals by Means of Their Chemical and Physical CharactersMinor corrections and revisions have been made in many places and somewhat more specific instructions have been added concerning manipulation in the use of some of the tests, as, for example, the reduction of metals on charcoal, page 14.While the adoption of uniform laboratory methods in different institutions is scarcely to be expected, even if desir able, it is believed that the rules and suggestions inserted on pages 62 and 65a may prove serviceable. They are based on many years' experience in trying to develop in the immature student habits of neatness, orderliness, and accuracy, and at the same time to inculcate a certain respect for mineral speci mens, both in the laboratory and in the field.This book has been designed for the use of students in determinative mineralogy and also to meet the needs of the geologist and the mining engineer. The tables give the phys ical and chemical properties of 380 minerals (100 to 150 more than the current text-books), while the arrangement is such that unknown minerals may be determined quickly and easily. The names are printed in three sizes of type intended to suggest some idea of their relative importance. Species that have been omitted are very rare and, from the practical point of view, of no importance.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
