582 EXPEBIMENT STATION RECORD. 



"Wassermann's method in the diagnosis of dourine, T. Pavlosevici (Arhiva 

 Vet., 7 (1910), No. 2, pp. 69-82; abs. in Jour. Trap. Vet. Sci., 6 (1911), No. 2, 

 pp. 203-205). — The author concludes that "antibodies demonstrable by "Was- 

 sermann's method are formed in the serum of animals suffering from acute 

 forms of trypanosomiasis. These antibodies are not specific either for races or 

 for the genus. The serum of such animals does not show Landsteiuer's phe- 

 nomenon." 



The author was unable to demonstrate antibodies in dourine by Wasser- 

 mann's method by the use of the antigens he employed. 



Foot-and-mouth disease in suckling's, D. Geeo {AUuiorrofii Lapolc, S.'f 

 (1911), No. 16, pp. 1S5-J87; ais. in Berlin. Tierfirzih Wc^ivfichr., 21 (1911). No. 

 3'h p. 612). — Death was found to be most frequent with 2 to 3- weeks-old ani- 

 mals. On section some animals were found to have an acute g;istro-intestinal 

 catarrh and parenchymatous and waxy degeneration of the heart muscle. In 

 many instances, however, the autopsical findings were negative. 



After these observations were made the milk was boiled before feeding, as 

 a result of which the mortality has been reduced considerably. 



The meiostagmin reaction in foot-and-mouth disease, A. Ascoli (Ztschr, 

 InfektionHlcrank. u. Hyg. Haustlcre, 8 (1910), No. .'i-o, pp. 308-321).— As a 

 result of his work the author believes that this reaction will eventually be of 

 value for detecting carriers of the virus of foot-and-mouth disease. The 

 meiostagmin reaction can also be employed for diagnosing tuberculosis and 

 glanders (E. S. R., 24, pp. 779, 780). 



The laboratory diagnosis of glanders, B. L. Asms (Jour. Amer. Pub. Health 

 Assoc, 1 (1911), No. 11, pp. 839-846). — A discussion of the procedures and value 

 of the various methods proposed for the laboratory diagnosis of glanders, with 

 particular reference to the complement fixation method. 



The eye test in glanders, ScHNiJRER (Deut. Tierarztl. Wchnschr., 18 (1910), 

 No. 5, pp. 65-69; abs. in Ztschr. Imnmnitatsf. n. Expt. Ther., II, Ref., 2 (1910), 

 No. 6, p. 7). — A critical discussion in regard to the work of various authors 

 with the opthalmo reaction. According to this author the method is a good 

 one, and the unsatisfactory results obtained with it by various workers are 

 probably due to the use of nonuniform mallein preparations. 



Vaccinating against rabies by a dilute virus, T. Oshida (A 6s. in Ztschr. 

 Immunitdtsf. u. Expt. Ther., II, Ref., 2 (1910), No. 13-lJf, p. 323).— Fresh 

 " virus fixe " is diluted 100, 200, 400, 800, 1,600, 3,200, and 6,400-fold, so as to 

 produce emulsions which finally contain from 0.3 to 0.5 per cent of carbolic 

 acid. For the initial vaccination 1 cc. of the 6,400-fold dilution is given, and 

 for the second, the 1-3,200. Treatment is continued until each dilution has 

 been given. After this the whole cycle is repeated. The results with 80 cases 

 were good. 



The resistance of tubercle bacilli to dry heat, C. Krumwiede, Jr. (Jour. 

 Infect. Diseases, 9 (1911), No. 2, pp. 115-116). — The material employed in this 

 work consisted of 8 three-weeks-old cultures of the human type of bacillus 

 isolated on glycerinated egg media. The results show that air-dried tubercle 

 bacilli are more resistant to dry heat than bacilli heated in fluids or steam. 



The reaction curve in glycerin broth as an aid in differentiating the 

 bovine fi'om the human type of tubercle bacillus, M. Grund (Jour. Med. 

 Research, 25 (1911), No. 2, pp. 33-5-357, fig. 1). — A large number of strains iso- 

 lated from 478 unselected cases in man and some in cattle were tested with this 

 method. In most instances tests were begun only after the various strains had 

 been cultivated on artificial media for some time. The final reaction recorded 

 represents the average of 3 flasks, except in a few instances where extensive
