This is the second edition of Dr. Allen's excellent book. The first edition was published in 1937 and, as the jacket states, has been translated in many languages, including Italian and Bengali. Dr. Allen in simple, understandable language discusses the development of present day psychology from Janet through Mesmer and Morton Prince to Freud, Adler and Jung. There are also chapters devoted to Pavlov's conditioned reflex experiments as well as the contributions of Wagner-Jauregg and Kretschmer. There is a good bibliography, although, as has been done by many English authors, the contributions of American writers have been largely, although not entirely, ignored. This is only a minor criticism; the book is highly recommended to all students who are interested in the problems of human behavior.
