THIS work makes a highly important and extremely useful addition to the. number of English Veterinary Text-Books. The well-known treatise on Comparative Ophthalmolo~y by the French veterinarian, Dr Eugene Nicolas, has been reproduced and considerably amplified by Mr Henry Gray, who can be heartily congratulated on this work, whIch has been very well done. It contains much information on the eye considered from an optical point of view, a fairly exhaustive description of the different methods of examining the eye, and a full account of the various diseases of the con­junctiva, sclera and cornea, uveal tract, retina and optic nerve, crystalline lens, vitreous humour, orbit, eyelids, and lacrimal apparatus, with carefully stated details of the diagnosis and of the surgical and other treatment of every important affection of the eyes in animals. Here the veterinary surgeon of mature experience will find much to quicken his resipiscence. The sections are well arranged, the text is reliable, instructive, and always intelligible. The description of irido-cyclitis (specific ophthalmia) is deserving of special commendation. The illustrations vary in merit, many being good and a few only moderate, but they serve to elucidate the text, which is their main purpose. The book is clearly printed, convenient to handle, and a credit to the publishers. No earnest practitioner should be without a copy, and we venture to predict that a second edition will soon be wanted, when, doubtless, the Editor will take the opportunity to dispense with the rather numerous corrigenda which constitute a blot in an otherwise admirable reproduction.
