Excerpt from A Pocket Handbook of Minerals: Designed for Use in the Field or Class-Room With Little Reference to Chemical TestOF works on mineralogy, there are a great number, but most of these are too cumbersome to be carried into the field and the descriptions are often so obscured with unim portant details as to make them of limited value except to specialists.Of handbooks and tables on the subject, there are not a few, but these are mostly so condensed as to confuse rather than aid, are also often lacking in important details, and almost without exception they place the emphasis upon chemical, rather than physical distinctions, thus greatly limiting their value to one in the field.This work is designed to occupy a middle ground. Al though of pocket size, it aims to give all the details which may be needed to identify most of the minerals which mining men, students, or collectors are apt to encounter, and the emphasis is always placed upon characteristic physical features little details which would ordinarily be overlooked by all but trained mineralogists, and which are often unknown to these if their training has been too closely confined to the chemical side of the science.Nothing is herein included which may not be needed in the pursuit of the end for which the book was prepared, i.a., the determination of minerals, and it is to be hoped that little has been omitted which might further that end.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
