Immunization of calves against tuberculosis, F. Onpracek (Wiener Laridic. 

 Ztg.. .57 (l!)07). Xu. 11, p. 93). — Al'ter a lonji cxiHTiciR-e with methods of con- 

 trolling tuberculDsis, the author reeouimends the clinical examination of cattle 3 

 times annually, diagnostic inoculations with tuberculin annually, and the vacci- 

 nation of calves by the method of von Bchring. 



Vaccination for tuberculosis in cattle, Hossignol and II. Vallee {Rev. 

 Tuberculose, 2. at/-., 3 (1906), Xo. 6, pp. .',6(}-'i72). — As the result of previous 

 experiments in vaccinating cattle against tuberculosis at Melun, the authors 

 came to the conclusion that vaccinated animals resist natural contagion from 

 cohabitation with infected animals at least for a period of sevei-al months. 



Further experiments have been carried out and animals previously treated 

 have been kept under continued observation. It appears that bovo-vaccine 

 shows some variation in virulence, as tested on guinea pigs, and it is therefore 

 reasonable to suppose that its effects on cattle are not always identical. Cattle 

 vaccinated by this method may be infected with tuberculosis by intravenous 

 inoculation within 3 months, and immunity disappears entirely in some cases 

 within a year. It was found that the resistance of vaccinated cattle to con- 

 tagion from association with tuberculous cattle was not particularly marked and 

 did not extend over a period of more than a few months. Judgment is there- 

 fore suspended regarding the ultimate value of tills method of vaccination. 



Tuberculosis of the esophageal musculature in cattle, May (Deut. Tier- 

 (irzil. Wclnisclir.. ].', {19111). So. 3. pp. 31. 32). — The tissues along the trachea 

 and esophagus, particularly the lymphatic glands, are often involved in cases of 

 pulmonary tuberculosis in cattle. In one instance the author observed isolated 

 tubercles in the musculature of the esophagus and was led to believe that these 

 tubercles were due to a secondary infection from bronchial slime. 



Diagnosis of anthrax in practice, L. De Blieck (Tijdsehr. Vecartsenijk., 

 3'f [190C>). A'o. 3. pp. 109-151. pi. 1). — A detailed account is given of the means 

 which may usually be adopted by the practicing veterinarian in making a bacte- 

 riological diagnosis of anthrax. The general discussion includes methods of 

 identifying the anthrax bacillus, differential diagnosis between anthrax and 

 related diseases, and the approved methods of sending material to laboratories 

 for a bacteriological test. 



Determining the effectiveness of anthrax serum, A. AscoLi (Zt.sichr. Hi/g. ii. 

 Infcktiini.skninl:. ■'>■'> {19(lii). Xo. 1. pp. 'I'l-Slh. — As a result of a long series of 

 laboratory experiments, the author comes to the conclusion that the intravenous 

 inoculation of anthrax serum gives rabbits a pronounced passive immunity 

 toward virulent anthrax cultures. The results which are obtained within 24 

 hours after the injection, however, are not sutlicieutly regular to form a basis 

 for determining the value of the serum. 



Under certain conditions anthrax serum has the power of protecting guinea 

 pigs against cultures of anthrax bacilli. The passive immunity produced by 

 intraperitoneal injection of anthrax serum is manifested within 24 hours, 

 whereas after subcutaneous injection it does not ajipear before 72 hours. 



A microscopic study of the colostrum and the udder of cows in cases of 

 parturient paresis, N. P. KrKiii.YADEV (Ivlicii. Zap. Kazan. Vet. hint.. 23 

 (1906), No. 5-6, pp. 351-390, pi. 1). — An elaborate microscopical .study was made 

 on 14 cases of parturient paresis in cows for the purpose of identifying the vari- 

 ous bodies found in the colostrum and udder in such cases. 



During this investigation the author found in the colostrum casts and other 

 bodies closely resembling them in structure, but b.-wing a different contour, and 

 also fat globules, leucocytes, red blood and colostrum corimscles. epithelial cells, 

 and granular amorphous masses. The colostrum in cases of parturient .paresis
