VETERINARY MEDICINE. 



The prevention and treatment of diseases of tlie domestic animals, K. 

 WiNSLOW (New York, 1910, pp. 303, pi. 1). — The modern treatment of the more 

 common diseases of domesticated animals is presented in a conveniently arranged 

 form. 



The people's home stock book, W. C. Fair (Cleveland, Ohio, 1910, pp. 

 V-[-315, pis. JfS). — This is a popular account of diseases of domestic animals and 

 the methods of treatment therefor. 



A text-book of histology, F. R. Bailey (New York, 1910, 3. ed. rev., pp. 

 XVIII+589, pi. 1, figs. 354). — A thoroughly revised and partly rewritten edition 

 of this work. 



Manual of poisonous plants, L. H. Pammel (Cedar Rapids, Iowa, 1910, 

 pt. 1, pp. VI +150, pis. 5, figs. Ji2). — This manual deals chiefly with the poisonous 

 plants of eastern North America. Chapters are devoted, respectively, to poisons 

 and statistics on poisons; bacterial poisons; dermatitis, forage poisoning, ergot- 

 ism, and aspergillosis; poisoning from fungi; poisoning from other plants (4 

 chapters); poisoning from flowers, honey, and mechanical injuries; classifica- 

 tion of poisons, symptoms, and antidotes; the production of poison in plants; 

 algte in water supplies; a catalogue of the more important poisonous plants of 

 the United States and Canada ; and the chemistry of alkaloids, glucosids, etc. 



Further observations on the immunization of animals to the poisons in 

 fungi, W. W. Ford (Jour. Pharmacol, and ExpU Thcr., 2 (1910), No. 2, pp. 

 1J,5-152 ) .—Contmning previous work (E. S. R., 18, p. 82C ; 21, p. 629), 3 dif- 

 ferent substances in fungi, the Amanita (A. phalloides) hemolysin, the Amanita 

 (A. phalloides) toxm, and the Muscaria (A. muscaria) agglutinin, were tested 

 at some length with regard to their power of stimulating animals to antibody 

 formation. 



Only one of these, the Amanita hemolysin, acts like a true toxin in this 

 respect, and with this poison the immunization of animals has now been car- 

 ried out on so many different occasions and the sera produced have such definite 

 and lasting antihemolytic properties as to leave little doubt of the definiteness 

 of the reaction. The fact that the author's chemical investigations indicate that 

 this hemolysin must be classed as a glucosid, and that animals may be im- 

 munized to it after it has been freed of proteid, raises important questions in 

 regard to immunity production, and suggests that the study of other substances 

 than the toxic proteids may throw some light upon that remarkable phenomenon 

 in which the tissues and cells of the animal organism throw out protective sub- 

 stances when certain poisons come in contact with them, but fail to react in 

 this way under the influence of other poisons. 



The principles of pathology (Philadelphia and New York, [1908], vol. 1, 

 pp. Xyi'\-9Ji8, pis. 16, figs. 322; 1909, vol. 2. pp. XV+1082, pis. 15, figs. 310).— 

 The first volume of this work, by J. G. Adami. is devoted to general pathology ; 

 the second, by J. G. Adami and A. G. Nicholls, to systemic pathology. 



A text-book on disease-producing micro-organisms especially intended 

 for the use of veterinary students and practitioners, M. Herzog (Philadelphia 

 and New York, 1910, pp. XI+6U, Pls. l-'h figs. 2i//).— This text-book is divided 

 into four parts, namely, (1), the theory and practice of general bacteriology (pp. 

 17-192) ; (2), special bacteriology (pp. 193-449) : (3), micro-organisms in foods 

 and soils (pp. 451-527) ; and (4) pathogenic protozoa (pp. 529-619).
