This is a very simple account of 'Modern Medical Psychology', written by a layman for laymen, with a preface by Dr. William Brown, whose influence is apparent throughout. The descriptions are lucid and straightforward, but unsatisfactory to a Freudian reader by reason of their naïveté. There are some surprising remarks, e.g. that 'masturbation with very young children has nothing to do with sex' and that the transference 'needs careful encouragement by the doctor' until the patient can get across his own ditches by himself. 'The transference can then be broken.' The author accords full credit to Freud for the foundation of modern psychological medicine, but it is significant that his bibliography contains no psycho-analytical reference. It is possibly true that no publication of Freud himself is elementary enough for the particular public in view, but the omission of Ernest Jones's booklet Psycho-Analysis cannot be justified on such grounds.
