Excerpt from Mineralogy The first edition of this introduction to the study of Mineralogy was published in 1892. Since then the book has been reprinted three times, but till now without revision. Starting with the idea of a simple revision, I have found it necessary to rewrite and to enlarge it; but in doing this, I have been careful to retain the essential features of its original arrangement.
