This volume, as stated by the author, is a revision of the first edition with the addition of a chapter on surgical anatomy, prepared by the author in collaboration with Mr. O. V. Lloyd-Davies, and there are two other new chapters on injuries and sarcoma. Anything that comes from the pen of this author is worthy of consideration. The resources of St. Mark's Hospital are at his disposal and he has made excellent use of them in his vivid portrayal of the problems with which he deals. This volume contains all the illustrations and descriptive material of the splendid first edition and with the added features mentioned there has resulted a new book which is worthy of commendation. In the words of the author, it should be found useful to "proctologists, to general surgeons, and to general practitioners."
