VETERIlSrARY SCIENCE AND PRACTICE. 193 



Horse sickness, investigation, H. W. Pitciiford {Agr. Jour, and Min. Rec, 6 

 [1903), No. 8, pp. 249-257). — The author continues an account of his studies on the 

 etiology of South African horse sickness. It is believed that some flying insect, 

 j)robably a mosquito, is the carrier of infection. Horses kept in stables in which 

 smudges were maintained appeared to be protected against the disease, and the 

 author interprets this fact as due to the effect of smoke ujjon mosquitoes. 



Notes on the mallein test, G. Feist (FortsrJir. Yet. Ilyg., 1 {lUOS) , No. 1, pp. 

 30-3S). — Attention is called to the difhculties exjierienced by official veterinarians 

 in satisfying the minds of horse owners as to the diagnosis of glanders. Notes are 

 given on 286 cases in which the mallein test was made; among these horses 26 

 reacted and were found to be glanderous upon post-mortem examination. In the 

 author's experience no case was observed in which a glanderous horse failed to react, 

 and no reaction was jjroduced in horses which were not glanderous. 



The patholog-ical importance of botfly larvae in the stomach of horses, 

 E. Perroxcito {Fortschr. Vet. Ilyg., 1 {1903), No. 1, pp. 40-43). — A number of cases 

 have been reported in the literature of this suliject in which the stomach wall was 

 more or less injured by the presence of botfly larv;e. The author believes that the 

 attacks of these insects brings al)0ut greater susceptibility to colic and infectious 

 diseases. 



Insects which may aid in the spread of surra, J. C. Koningsberger ( Teys- 

 inannia, 13 {1902), No. 6, pp. 314-322). — On account of the resemblance in symp- 

 toms of surra and nagana the author believes that the former disease may be 

 conveyed in Java by some species of fly, as nagana is transmitted by the tsetse fly in 

 South Africa. Descriptions are given of several species of biting and sucking insects 

 which might be suspected of being carriers of surra. — ji. m. pieters. 



Natural immunity of dogs and chickens to anthrax, A. Petterssox {Cenihl. 

 Bakt. u. Par., 1. Alt., 33 {1903), .Yo.<?,j97J.5i5-6™^6^).— During the author's experiments 

 on this subject it was found that the serum obtained from chickens possessed essen- 

 tially the same resisting powers toward anthrax as that obtained from dogs. The 

 dog, however, is preferred in experiments of this sort for various reasons. 



A number of experiments were made by the auther for the purpose of determining 

 the properties of dog serum, especially in its reactions toward anthrax bacilli and 

 with regard to the stimulating effect upon the dog serum of serum from rabbits pre- 

 viously treated w'ith dog serum. It was found tliat rabbits which were treated with 

 the serum of dogs developed substances antagonistic to both the amboceptor and the 

 complement. Cytolytic immune bodies were produced by previous treatment of the 

 animals with cellular secretions. 



Rabies in South Africa, A. Loir {Ann. Inst. Pasteur, 17 {1903), No. 4, PP- 298- 

 302). — The author presents a brief description of an outbreak of rabies which 

 occurred in Rhodesia. On account of the seriousness of the outbreak as observed by 

 the author it was recommended that all dogs be muzzled and that all suspected dogs 

 and other animals be killed. As a result of the investigation 80,000 dogs were killed. 

 A number of experiments were made on rabbits for the purpose of determining the 

 virulence of rabies virus as obtained from various cases. 



Antirabies vaccine at the Pasteur Institute in 1902, E. Vial.\ {Ann. Inst. 

 Pastt'ur, 17 {1903), No. 5, pp. 365-3GS). — A table is given showing the number of 

 persons treated and the mortality in these cases from 1886 to 1902, inclusive. The 

 author discusses briefly also the history of the rabid animals concerned in these 

 cases. 



The histology of rabies corpuscles in the peripheral nerve ganglia, \ . F. 

 Otte {Uchcn. Zupiski Kazan Vet. Inst., 20 {1903), Nos. 2, pp. 237-245; 3, pp. 388-404, 

 pi. 1). — The microscopical structure of these corpuscles was carefully studied by the 

 author and is described in detail.
