vibrio can live outside the body. It seems to soon lose its pathogenicity when 

 cultivated; and serious outbreaks of the disease do not usually occur on the 

 same farm year after wear. But nevertheless there is some evidence that the 

 microbe may exist, sapropliytically or otherwise, outside the body of the 

 sheep. The symptoms, circumstances, post-mortem lesions, and microscopical 

 findings are all of imiwrtance in diagnosis. The agglutination test promises 

 to be of practical value here, and the complement fixntion test is also being 

 worked upon." 



The committee advance various recommondulions for prevention, including 

 destruction of virulent material, isolation of aborting ewes and disinfection of 

 their genitals, and the avoidance of penning ewes together in close proximity 

 before lambing. Thus far the committee do not consider legislntive measures 

 applicable to the disease. 



A new (?) strongyle causing parasitic gastritis in a goat, J. B. Buxton 

 (Vet. Jour., 70 UOU), No. Jf6h pp. 89-94, figs. 5).— The nematode here con- 

 sidered closely resembles the strongyle of Axe, which is found in the stomach of 

 the horse but apparo-itly cau.ses no ill effects, and the mrongylus gracilis of cat- 

 tle and sheep, from which, however, it differs in several respects. 



The detection of erysipelas in hogs with the precipitation method, L. 

 Drescher (Mitt. Kaiser Wilhehns Inst. Landto. Bromherg, 5 (1913), No 4, pp. 

 322-331; abs. in Berlin. Tierdrztl. Wchnschr., 29 (1913), No. 27, pp. Jf89, 490).— 

 As a result of the experiments conducted, the conclusion is reached that Ascoli's 

 thermoprecipitation reaction when used for diagnosing erysipelas in hogs is 

 without value for practical purposes. 



About the detection of antibodies in the blood of horses immunized with 

 voldagsen (hog cholera) bacilli and hogs affected with voldagsen cholera, 

 W. BuCHAL (Mitt. Kaiser Wilhelms Inst. Landiv. Bromherg, 5 (1913), No. 4, pp. 

 263-276; abs. in Berlin. Tierdrztl. Wchnschr., 29 (1913), No. 27, p. 490). — After 

 pointing out that bacteria present must also be considered when studying hog 

 cholera, the results of experiments made with the complement fixation, aggluti- 

 nation, and precipitation tests are reported. 



In conjunction with the tests some experiments were made with reference to 

 the valuation of immune sera produced in two horses which were previously 

 treated with voldagsen strains of bacteria. It w\'is noted that the sera of both 

 horses contained agglutinins, precipitins, and complement fixing substances, and 

 one of the horses showed a much greater antibody formation than the other. 

 No bacteriolysins were produced. The protective value of the sera for mice was 

 0.1 cc. and upwards. 



The sera of the hogs which had passed through a voldagsen or other infection 

 did not show the same constancy in regard to agglutinating, precipitating, or 

 complement fixing substances as the horse sera. Incidentally it was found that 

 the sera of sound hogs contained a normal precipitin for the voldagsen precipi- 

 tinogen. This normal precipitin was noted in horse serum also.

 strated for the first time the presence of living trichinre in the cerebro-spinal fluid 

 in vivo. Salvarsan as shown in cases treated is useless as a therapeutic agent.
