Dana's Manual of Mineralogy - For the Student of Elementary Mineralogy, the Mining Engineer, the Geologist, the Prospector, the Collector, Etc #223964

It was found that it was desirable to rewrite the book, and consequently, as far as the text and figures are concerned, this present edition is almost wholly new. The scope and character of the book, however, have been kept as nearly as possible the same. The book has been primarily designed to fill the ordinary needs of the elementary student of Mineralogy, the mining engineer, the geologist and the practical man who may be interested in the subject. It has been made brief and direct and the treatment has been as untechnical as possible. The chapter on Petrography has been omitted and only a brief and general description of the various important rock types given. This change was made in view of the fact that since 1887 the subject of Petrography has had so large a development as to render impossible its adequate treatment in a single chapter. Moreover, several elementary books on the subject.
