REVIEWS. 321

text is in many places very thin in regard to the information which is likely to be of most service to the veterinary surgeon in actual practice.

In the Bibliography of seven pages at the end of the book it is impossible to recognise on what principle the works mentioned in it were chosen, but some of the authors not included are made very prominent by their omission.

Chirurgische Operationstechnik. By Dr. Oskar Roder und Dr. Ewald Berge. Third Edition. Berlin: Paul Parey. 1935. Price, bound, 8.60 Rm.

In the new edition of this very practical guide to surgical operations the text has been revised and brought up to date by the inclusion of operations recently introduced and the addition of a number of illustrations. Naturally, it deals mainly with operations on the horse, but it also includes those of any importance in the other domesticated animals. Casting and other methods of restraint and anresthetics occupy the first 30 pages, and the following sections deal in succession with the operations on the different parts of the body. The illustrations, now numbering 124, and many of them coloured, add greatly to the practical value of the work. German students are to be congratulated on having such an excellent guide to their exercises in surgery.

The Physiology of Domestic Animals. By H. H. Dukes, D.V.M., M.S., Pro­fessor of Veterinary Physiology, New York State Veterinary College, Cornell University. Third Edition. Ithaca, New York, Comstock Publishing Company, Inc. 1935. Price 6 dollars.

There is probably no branch of a veterinary student's professional education that is more important than physiology, and if the subject is to be well taught the student must have the aid of a good text-book. The present work deserves to be so described. It is thoroughly up-to-date, the space devoted to each part of the subject is adequate to its importance, and the text is clear and concise. It can be strongly recommended both to teachers and students.

The Essentials of Histology. By Sir E. Sharpey-Schafer, F.R.S. Thirteenth Edition. Edited by H. M. Carleton, M.A., B.SC., D.PHIL. London: Longmans, Green and Co. 1934. Price 15s. net.

The call for a new edition of this standard work is evidence that it maintains the high place which it has long occupied as a guide to the study of histology. It extends to 605 pages, in which there are 721 illustrations, many of them coloured. It is hardly an exaggeration to say that nothing relating to the histology of the organs and tissues of the body is left to the student's imagination; all are presented to the eye with clearness and accuracy. It is, of course, primarily designed for medical students, but advanced veterinary students will also find it almost equally useful.

Topographical Anatomy of the Dog. By O. Charnock Bradley, M.D., D.SC., F.R.C.V.S. Third Edition. Edinburgh: Oliver and Boyd. 1935. Price 25s. net.

The new edition has been increased by a few pages, and it contains a number of new illustrations. These now number 80, and in them all the different parts of the body are displayed in their proper relationships.

To praise the book would be a work of supererogation; it remains unrivalled as a guide to the dissection of the dog.
