This book is written as an introduction to crystal physics for undergraduate and graduate students majoring in physics, chemistry and mineralogy. The first chapter by Schoenborn on Elemente der Kri- stallsymmetrie deals with crystal classes including those of the magnetic type. In the second chapter Ph~nomeno- logische Darstellung der Kristalleigenchaften the same author, after a brief mathematical introduction, discusses certain crystal properties by means of tensors. This includes, for example, pyroelectricity, pyromagnetism, conductivities, optical activity, double refraction, piezoelectricity, elasticity, etc. Chapter 1 appears too brief and superficial but the second chapter gives a good discussion of the mentioned physical properties. Kleber has written Chapter 3 Gitterphysikalische Eigen- schaften. He discusses crystal bonding, potential and vib- rations, and elastic, magnetic, dielectric and optical prop- erties. This is a very brief and rather unproblematic ac- count of the phenomena. Finally, Meyer gives
