This little book, says Col. Sir A. Lisle Webb in his foreword, aims at supplying a real need for a brief and straightforward account of the modern views of functional nervous disorders. This aim is only partly fulfilled, for no account is given of the knowledge of these disorders accruing from the psycho-analytic investigation of them. Further, one fails to find that anything other than what has been brought forward during the last two or three years in the more general literature on the subject, apart from the Freudian, has been discovered by the investigations of the two authors.

If the intention of the authors was to expound the modern views, surely those of Professor Freud and his followers should have been included, even if the writers themselves were unable to accept them.

This book in one direction is an advance on so many others of a like nature, in that the authors have eschewed the term "Psycho-Analysis" and use the term "Mental Exploration" for their investigations in the psychical sphere.
