This is a scholarly exposition on diseases of the kidney. While the outline of the book has been changed little from its previous editions, the material has undergone a thorough revision and includes practically all the recent advances in the subject. Because of the exhaustive nature of its contents it will not be possible to give a detailed review in this column. The organization of the monograph allows the presentation of a vast amount of data to the reader in a concise form. The opening chapters concern themselves with definition and classification and the following chapters are on the anatomy and physiology of the kidney. It would seem that the reader might obtain a more comprehensive conception of the terms if he had first read the excellent chapters on anatomy and physiology. Few books on the kidney have presented the subject in such a fundamental way as this one does.
