The Topographical Anatomy of the Head and Neck of the Horse. By o. Charnock Bradley, M.D., D.Sc., M.R.C.V.S. Edinburgh: W. Green & Son, Ltd., 1923. Price 2 IS. net. THE present instalment completes Professor's Bradley's work on the topographical anatomy of the horse. It extends tc 214 pages and includes 96 illustrations. It is quite up to the high standard of the previous portions of the work, and the three volumes together form a valuable addition to Veterinary Anatomy. The Dentition of the Camel. By D. S. Rabagliati, O.B.E., B.Sc., F.R.C.V.S., Director of the Serum Institute, Ministry of Agriculture, Cairo, Egypt, etc. Government Press, Cairo, 1924. Price P.T. 5. DURING the late war the author was in command of a large veterinary hospital equipped and run entirely for the treatment of camels, and in this way nearly 25,000 camels passed through his hands. It is fortunate that he seized this opportunity to make observations regarding the dentition of these animals. He determined to find out for himself, as far as possible, what are the normal types and characters of the teeth and when they really erupt. Such information on this head as was obtainable from Bedouin Arabs was found to be quite untrustworthy, and the descriptions of the teeth given in the work are based on the author's personal observations of a very large number of mouths of camels, and on the inspection at short intervals of the mouths of a few camels whose ages were known to a day. All the teeth, temporary and permanent, are described in detail in the text, and a special merit of the work is the copious manner in which it is illustrated, there being no fewer than 27 full-page large lithographic plates. The work will prove indispensable to veterinary surgeons and others in those countries in which the camel is a common animal. Disease in Captive Wild Animals and Birds. By Herbert Fox, M.D., Pathologist to the Zoological Society of Philadelphia, Director of the William Pepper Clinical Laboratory, University of Philadelphia. Published by J. B. Lippincott Co., Philadelphia, London, and Chicago. 1923. Price £3. A STUDY of the pathology of wild animals in a state of captivity deserves to be prosecuted, first, because it is the only means by which one can expect to prevent or reduce the losses which are occasioned by disease in zoological gardens and similar establishments, and, in the second place, because of the expectation that it may throw further light on certain more or less obscure diseases affecting man or the domesticated animals. The present work, which is the outcome of the author's twenty years' experience as Pathologist to the Zoological Society of Philadelphia, may be welcomed for the good which it will do in both of these directions. Dr Fox has brought to the task that knowledge of human pathology which was necessary as a basis for comparison, and he has succeeded in presenting the observed facts and the conclusions deduced from them in a manner which is at once clear and attractive. The records of autopsies at the Zoological Garden in Philadelphia themselves number nearly 6000, but additional data culled from published reports of other gardens have been made use of by the author.
