A translation, slightly abridged, of a well known German work. “This volume, of absorbing interest, outlines a life which was intimately bound up in the life of the scientific world during the last century.” (Nation.)
“Care has been taken to retain what is essential, and the work has therefore suffered but little. The translation has been carried out with skill, and the writing is on the whole good.”

A book intended for beginners. “A bibliography of forty-one titles of important reference books and articles is at the beginning of the book. This is followed by a sixteen-page general discussion of the properties of crystals their arrangement into systems, the symbols used, the symmetry, and tractional forms. The systems are then taken up in order, beginning with the cubic and following through to the triclinic. The relations of axes, symmetry, and possible classes are taken up with considerable care in each system.” (J. Geol.)
