The author is profoundly grateful to the medical profession for the kindly reception accorded the first edition of this book. The exhaustion of a large edition since its appearance nine months ago attests its popularity.

The practicability and efficacy of psychotherapeutic procedures, as an adjunct in the treatment of disease, is no longer questioned by physicians who have personally tested the methods herein advocated.

The present edition has a more complete index, and has been brought up to date by the addition of new material on those phases of the subject on which advancement has been made during the past,year in so far as such advancement is deemed of practical value to the general practitioner in the present evolution of psychotherapy.
