of cicutin hydrobromid into a mare which had already mnnifested general 

 symptoms of tetanus yielded excellont results. 



A contribution to the ophthalmic tuberculin test for the diagnosis of 

 bovine tuberculosis, A. M. Bebgman {Ztschr. Infektionskrank. u. Hyg. Haus- 

 tiere, 17 {1915), No. 1-2, pp. 57-67, p/s. S). — Tabulated experimental data are 

 reported and discussed. 



A tut)erculin consisting of 92 per cent of a bovine strain and 8 per cent of 

 a human strain with 40 per cent glycerin was found to yield excellent results. 

 Of 107 animals tested. 87 were tuberculous and 20 nontuberculous. Of the 

 tuberculous animal.s, 70 reacted positively, 11 were doubtful, and 6 negative. 

 Of the 20 nontuberculous animals, one reacted positively. A second test on 

 the same eye yielde<l identical results. From the results thus obtained the 

 ophthalmic test is considered to be the most preferable diagnostic test, espe- 

 cially in ca.ses where the animals have been previously sensitized. In the first 

 tuberculin test a sympathetic reaction in the untreated eye was obtained in 

 about 4 per cent of the positive reactions. 



A previous sen.sitization Is considered to be of value not only in yielding a 

 more distinct second reaction but also In bringing about an earlier respon.se 

 after instillation of the tuberculin. Ri'peateil instillatious of tuberculin at 

 Intervals of from one ti> tlin-e days were founil to cause a decrease in suscepti- 

 bility after four instillations. The reaction was evident very early, but ai.so 

 disappeared early. In some cases five hours after the instillation. The ability 

 of the eye to become accustomtHl to repeatetl treatment of tuberculin is con- 

 sidere<i not to be of any practical signiticance. 



Bovine tuberculosis and milk for children, G. llET.NfcR (Dcut. yrllj.<<rhr. 

 (jffentl. Oandht.'-vflepr, 47 {1915). No. 1: nhs. in Internal. Ccntbl. Gegam. Tuber- 

 kulo.9e Forxrh., 10 {19 IG), No. 6, p. 166). — The author conchides that human 

 tuberculosis is transmitted chiefly from Individual to individual, but the dis- 

 ease may als4> be tDUismitlivl by hovines with ofUMi tuberculosis. esjX'clally udder 

 infections. In such cases milk is the carrier of the infection, and the infection 

 in most cases takes place in childhood. In a camiiaign against the disease 

 measures against the transmission of the disease from individual to individual 

 mu.st be devised and all |)ossiliilities of inft'ction from bovine sources eliminated. 

 Only milk from tuberculo-sis-fri-e animals should be us<^m1 for children. The 

 usual hygienic measures in conne<"tlon with the use of milk must al.so be 

 .strictly observed. 



Box elder poisoning. H. G. Bond {Vet. Alumni (Junrt. [Ohio Stnte l'niv.\. 

 4 {1916), No. 5. pp. Ill, 112). — This is a reiH)rt of the poisoning of cows through 

 feeding on the leaves and seed P4m1s of box elder, which resulte<l fatally in three 

 of the four animals affected. 



Malignant catarrhal fever of cattle in Kansas, L. W. Goss {Vet. .Alumni 

 Quart. [Ohio State Vnir.]. 4 {1916). No. 1, pp. 4-6). — This reports upon studies 

 made of cases of this disease during an outbreak which tfM>k place in the fall of 

 1916. 



Bovine onchocerciasis in South America, Piettre (/?m/. Soe. Cent. yf<^(l. 

 Vit.. 92 {1916). No. I4. pp. 202, 20a) .—li is state«l that an Onchocerca which 

 resembles O. gihuoni. although differing to some extent, has been found to 

 occur frequently in cattle sla\ightere<l in Sotith America. At the Frigoritlco La 

 Negra in Argentina 70 per cent of the cattle show extensive lesions on the 

 cervical ligament and 25 i>er cent localiz:itions on the external face of the great 

 trochanter. At the Frigoriflco T'rugunya in I^rugu.iy 00 \\or cent show cervic:il 

 lesions and 18 per cent lesions on the trochanter. The localization of this 

 Onchocerca Is quite different from the type occurring in France.
