LIFSHITZ have provided a well-planned and carefully executed book that serves to provide both a broad theoretical foundation in a currently active field and a bridge between topics often treated separately in books on electromagnetic theory and solid-state physics. The translators are also to be commended for a fine piece of work.

concerning these materials are now both timely and very much needed. The book by HILSUM and ROSE-INNESrepresents a notable contribution to the literature on this subject. It is a book for the expert or the serious student, since it is quite compact and presupposes a reasonably thorough knowledge of the fundamentals of solid-state physics. Its usefulness R. W. P.
