TiE following tables have been arranged for the use of the students of the School of Mines. They have been condensed from the lectures and are intended to familiarize the student with the principal characteristics of minerals, so that by the aid of two or three questions, relating to the operations they would be obliged to perform in the field, a mineral can be determined. They have been used with marked success in the practical study of mineralogy for several years. T. EGLESTON, JR. SCHOOL OF MIES, 1871. CLASSIFICATION OF THE SPECIES ACCORDING TO CRYSTALLINE FORM.
