Professor Hugo Muensterberg's newest work has just left the German press, being a volume of 767 pages entitled "Grundzuge der Psychotechnik." It covers ground which had not been systematically treated in any language, developing the application of psychology to education, law, commerce, industry, politics, social reform, art, history, natural science, and medicine. Some of these topics are discussed in an elementary form in his less technical books, "Psychotherapy," "On the Witness Stand," "Psychology and the Teacher," "Psychology and Industrial Efficiency," and in a little volume to appear this month, "Psychology and Social Sanity," but while all these books were written for the general public, the "Psychotechnik" is a strictly scientific work, intended solely for the student and the scholar. Professor Muensterberg himself intends to translate the volume into English next winter.

His book, "Psychology and Industrial Efficiency," which he published in English last spring, has in the mean time been translated into German, French, Spanish, Swedish, Russian, and Japanese.
