This is the ninth edition of this work which has appeared in the last twenty-eight years. That the book has been able to hold its own all these years is an evidence of the possession of excellencies which are appreciated.

The author is at his best distinctly when he is dealing with the organic disorders of the central nervous system, and the chapters dealing with these disorders are adequately and clearly treated from the point of view of a text-book. The portion that deals with functional disorders is correspondingly inadequate and disappointing.

In his preface the author discusses his failure to attempt to deal with the nervous system in accordance with the various evolutionary levels. He has in fact dealt with it largely on the basis of a practical division, for the most part anatomical. The book suffers from this lack of a coördinating point of view. There is a chapter on medical psychology.
