This volume was published in serial form in the Psychoanalytic Quarterly during 1940 by a former German psychoanalyst. The work was originally written in German and subsequently translated into English. The author has been the "textbook writer" of psychoanalysis during the last decade and apparently has adopted the role of interpreter of Freud. He has gathered together data concerning several technical problems and presents the material in easily understandable form, usually adhering to general principles. The book is authoritative and generally valuable, but the student should be cautioned against expecting to learn technic from this or any other text-book. Only from much personal experience is this possible.
