colts which gave symptons of being infested with hot flies. In all 48 gm. were given 

 to each animal. The remedy was endured well by the colts, although in a few 

 cases slight poisonous effects were noted. After a period of 3 days the bot-fly 

 larva? passed away in great numbers and the animals recovered their normal con- 

 dition rapidly. 



The susceptibility of hogs to fowl cholera, V. Stang and F. Pfersdokff 

 {Dent. Tliiemrztl. Wchnsdir., 9 [1001), No. U, pp. 139, 140).— A\\ investigation was 

 made of an outbreak of a disease among hogs, turkeys, and fowls. A bacterio- 

 logical study was made of the organism, which was isolated from dead animals, and 

 it was found to be that of fowl cholera. All these animals are apparently susceptible 

 to fatal infection from this organism. 



Inoculation against hog cholera, J. Webster {Tijdschr. Veeartsenijk. Maan- 

 blad, '28 {1901), No. 6, pp. 260-265). — The author reports a comparative test of the 

 Lands1)erg serum, the method of Lorenz, and Susserin in preventive and curative 

 inoculation for hog cholera. 



Treatment of glanders, W. C. Langdon {Jour. Comp. Med. and Vet. Arch., 22 

 {1901), No. 4, pp- -46, 247). — The author gives a brief supplementary report con- 

 cerning 25 cases of glanders which were appai'ently cured by repeated injections of 

 mallein. The majority of the treated horses had been ciuarantined and put to 

 ordinary farm work and had been used in this way from Ig to 2i \ears, without the 

 development of any symptons of the disease. The curative treatment wliich the 

 author used required from 5 to 8 weeks and cost from §10 to §15 per head. 



Experimental diagnosis of glanders by, means of inoculations into the 

 peritoneal cavity of guinea pigs, V. Galtier {.Tour. Med. Vet. et Zootech., 5. 

 ser., 5 {1901), pp. 129-1.33). — In a<ldition to other bacteria which were found asso- 

 ciated with the glanders bacillus in the nasal discharge of glanderous horses, a round 

 species was found which when inoculated into the peritoneum of guinea pigs along 

 with the glanders bacillus, multiplied to such an extent as to obscure the laresence 

 of the glanders bacillus. The glanders bacillus, however, in the experiments of the 

 author ultimately produced the characteristic reaction in male guinea pigs. 



A contagious stomatitis of horses in South Africa, Theiler {Devi. Thier- 

 cirztl. Wchnschr., 9 {1901), No. 13, pp. 131,132). — A description is given of an out- 

 break of this disease, together with an account of the symptoms. The majority of 

 cases recovered after a few days. The symptoms were those of acute inflammation of 

 the mucous lining of the mouth and tongue, and a discoloration of the tongue which 

 gave the disease the name of blue tongue. The disease was shown to be highly con- 

 tagious and in many respects resemb.led foot-and-mouth disease of cattle; but the 

 latter disease did not exist in South Africa at the time. 



Serum therapy in gangrenous septicaemia, E. LECLAiNCHEandC. ]Morel {Ann. 

 hut. Pasteur, 15 {1901), No. 1, pp. 1-16). — The normal serum of soliijeds was found 

 to possess very little immunizing power. Occasionally a horse was found from which 

 a normal immunizing serum was obtained. Cattle, which are naturally refractory to 

 the disease, possess a normal serum of con.siderable immunizing power. The normal 

 serum from goats and sheep showed little active influence upon the septic vibrio. In 

 order to procure an innnunizing serum, the authors made use of intravenous injec- 

 tions of small doses of virus. The ass was chosen as the experimental animal. Sub- 

 cutaneous injections of septic virus were also made on the same animal. Three series 

 of experiments were conducted, one by subcutaneous injection, the second by intra- 

 venous inoculation of blood cultures, and the third by intravenous inoculation of 

 cultures in bouillon. The results of these experiments may be briefly summarized 

 as follows: It is possible to obtain a serum which produces immunity against the 

 <3e\)tic vibrio. The best method of procedure consists in intravenous inoculations of 

 soupeds in series with cultures of the vibrio in ^lartin bouillon. The serum thus 

 obtained possesses preventive properties, and under certain conditions a curative
