Kanner covers the whole field of child psychiatry and the related field of child neurology. Personality disorders are described in a broad and comprehensive manner. Neurologic conditions are discussed only as they must be included in the general picture of behavior. The book is divided into two parts. The first discusses in a general way mental hygiene, clinic methods and attitudes. Part two describes the organic conditions of the central nervous system, glandular conditions briefly, signs and symptoms of personality disorders in children and the correct attitude to be assumed toward the various conditions. Kanner takes an objective attitude. He describes behavior disorders accurately and gives the general etiologic factors back of them. The psychoanalytic attitude is rather violently rejected. The book is on a "common sense"—often superficial—basis. The material is presented in an interesting manner. The book can be recommended as a safe, conservative, introductory text to the psychiatry
