This is an unusual piece of work. The author, although not a medical man, is well acquainted with the literature in the field of psychiatry and in the modern lines of neurology and has produced a book in which many points of view are well integrated. He discusses the abnormal mind with the attitude of one objectively dissecting, taking from one school of thought something and rejecting other concepts. He uses what is of value of each of the modern schools of psychiatry. He discusses the psychology of the neurosis, of the feebleminded, and of certain special disorders in a masterful manner. His criticism of psychoanalysis is well worth reading, and his discussion of the limitation of the anatomic method is of equal importance. The entire work is refreshing and sound.
