Mr. Cripps' well-known work on the rectum comes to us in a new edition, revised, and enlarged by the addition of matter of much value. The commoner diseases of the rectum are treated in thoroughly modern fashion. The section devoted to cancer of the rectum is particularly thorough and contains an extensive table of cases. Full reports of illustrative cases are characteristic of the book. We note the omission of any reference to colopexy in the chapter on prolapse of the rectum, our author recommending only cauterization or excision as methods of treatment for that ailment. With this exception the book is a valuable accession to the literature of this specialty.
