The modern developments involving ultrasonic generators and detectors, piezoelectric resonators and phonon inter- action with X-rays and other types of radiation all require an understanding of the transmission of elastic waves through solid bodies and especially through crystals. Many standard works on the physical properties of crystals have one or more chapters devoted to the study of the propaga- tion of plane elastic waves through crystals of various sym- metries. However, the book under review is remarkable in that it is entirely devoted to this subject. It is based on a series of lectures given to graduate students in Moscow University but it would be misleading to imply that it is a book which students will find easy to read. It has the cha- racter of a monograph rather than that of a student
