inoculation with cholera blood and by exposure, and the post-mortem examina- 

 tion showed typical hog-cholera lesions." 



Of 8 hogs injected intramuscularly with B. coli communis, 3 became ill, 1 

 dying after inoculation with a cholera blood filtrate, while 5 showed no 

 symptoms of disease, although 3 died after an exposure to hog cholera. All of 

 4 hogs that were fed bouillon cultures of B. coli communis became sick and 1 

 died ; of the 3 that survived, 2 died on exposure to hog cholera. 



Milk and bouillon cultures of a Micrococcus found in cholera blood were 

 injectetl intramuscularly into 6 hogs. Of these 3 developed marked symptoms 

 of disease and 3 became slightly ill when injected with large quantities of the 

 culture and on exposure to hog cholera developed a fatal form of the disease. 

 Eleven hogs were inoculated with blood filtrates from hogs having acute hog 

 cholera, and the disease affecting the 5 hogs that became sick was proved to 

 be hog cholera by inoculation and exposure tests. 



Hog cholera and hog-cholera vaccination, M. H. Reynolds {Amer. Vet. 

 Rev.. 36 {1910). Xo. .5, pp. 5-'iD-560). — A general review of the subject presentetl 

 at a meeting of the Minnesota State A'eterinary Medical Association, July, 1909. 



An outbreak of infectious equine nasal catarrh, I. Okresz (Allatorvosi 

 Lapok, 32 {1909), No. ^2, pp. 514, 515; abs. in Berlin. Tierdrztl. Wchnschr., 26 

 (1910), No. 11, p. 251; Vet. Rec., 22 (1910), No. 1134, p. 67,7).— The author 

 reports an outbreak of this nature which affected nearly all the horses of a 

 squadron of hussars in the beginning of June. The disease was introduced 

 through the horses which brought the litter-straw into the barracks, the virus 

 apparently being present in the litter. Altogether 92 per cent of those in the 

 barracks sickened after an incubation period of from 1 to 3 days. The dis- 

 ease could not be transmitted directly from horse to horse. 



The treatment of colic with barium chlorid, Loewenthal (Berlin. Tierdrztl. 

 Wchnschr., 26 (1910), No. 10, pp. 231, 232; ahs. in Vet. Rec., 22 (1910), No. 

 1132. pp. 614, 615). — Since 1905 the author has administered barium chlorid 

 intravenously in isr> cases of equine colic without any of the mishaps which 

 are said to attend its use. 



" While admitting that barium chlorid should be used with some caution, 

 on account of its cardiac toxicity, the author does not think that the cardiac 

 danger need be very greatly dreaded, even when the pulse is rather weak and 

 frequent. He lays stress upon the technique of the intravenous injection; 

 and in addition to scrupulous sterility of the syringe and solution, he em- 

 phasizes the necessity of carrying out the injection very slowly. He occupies 

 from one to two minutes in injecting the solution, and has never had a death 

 during, or in consequence of, the injection. . . . 



"He has had most brilliant results from the use of barium chlorid alone in 

 some severe cases of flatulent colic in which the pulse had already become 

 rather weak and frequent, the resi)iration was very difficult in consequence of 

 the intestinal distension, and the visible mucous membranes were dark red to 

 bluish-red." 



The agglutination test for glanders [in Prussia], Nevermann (Berlin. 

 Tierdrztl. Wchnschr., 25 (1909), No. 18, pp. 341-350; abs. in Jour. Com par. 

 Path, and Ther., 23 (1910), No. 1, pp. 62-64). — During the two years ended March 

 31. 190S. the agglutination test was employed on 3,466 horses. Of these, 648 

 were killed and 395 were found to be glandered. Of the total number, 2,085, or 

 60.16 per cent, showed a constant agglutinating power of 300-400 and 960, or 

 27.69 per cent, at 500-800. Among the horses with an agglutinating power at 

 300-400. there were 20, or 1.91 per cent, the first year, and only 9, or 0.87 per 

 cent, the second, and of these, 4 were destroyed on clinical grounds. Among the 

 animals with a permanent agglutinating power of 500-800 there were found 55 

 glandered animals, or 5.73 per cent. Horses with an agglutinating power of
