This little manual is a useful and accurate summary of psychiatry as it is seen through the eyes of a leading specialist. The chapter headings are the usual ones, on etiology, classification of mental diseases, methods of examination and the various types of psychoses. Part of a chapter is devoted to the psychoneuroses, and there is a short chapter devoted to defectives. About seven pages are devoted to some of the neuropsychiatric problems of war. The book is systematic and has a number of good illustrative case histories. It is remarkably complete for its small size.
