The first edition of this book appeared in 1908. Reviews of two previous editions have appeared in the Archives. The present volume, which is much larger than its predecessors, has been largely revised, although the general plan of the book remains the same. Some chapters have been entirely rewritten. American readers will be interested in the fact that important alterations in the legal definitions have been made by the Act of 1927; they have been incorporated in the present volume. The author has also wisely incorporated the investigations of E. O. Lewis, who, on behalf of the Joint Mental Deficiency Committee of the Board of Education and Board of Control, has made a new investigation regarding the number and condition of defectives in England. As conditions in England are in no way different from those in this country, the subject will be of equal interest to American readers.
