This book is a summary of a carefully organized mental hygiene plan, applying specifically to Yale University as the research laboratory, so to speak, but its usefulness extends to all similarly constituted groups. Throughout the book the reader is impressed with the diligence, insight and impartial judgement that stamp the whole project. It is a pleasure to see what methods of study were laid down and how they were developed and applied. If the book had no other value, it would still be very much worth while.

Of equal merit, however, is the mental hygiene study of 1, 257 students as patients. The many points of view from which the students were examined is a measure of the comprehensiveness of the undertaking. The reviewer is not without experience relating to the mental health of college students and can attest to the recommendations made in this book.

The Commonwealth Fund was as helpful to this work as were the many professional associates.
