because the saliva is not virulent. Suspensions of the salivary glands them- 

 selves are much more certainly infective under experimental conditions than 

 the saliva derived from them. This is more especially the case for the sub- 

 maxillary gland. Negri bodies are not always demonstrable in the brains of 

 experimental rabid animals, although they may become so after subpassnge." 



About the occurrence and the combating of rinderpest at the present time, 

 P. Knuth (ZtscJir. Infekiion.'ikrank. u. Tlyg. IlauHierc, 13 (1913), Nos. 5, pp. 

 273-293; 6, pp. 356-369).— A review of the literature pertaining to this topic, 

 accompanied by a bibliography embracing 51 titles. 



Trypanosomes of game and domestic stock, A. Kingiiorn and W. Torke 

 (Ann. Trap. Med. and Par., 7 (1913), No. 2, pp. 227-2.^8).— " Trypanosomes are 

 of frequent occurrence in game and domestic stock in northeastern Rhodesia. 

 As a conservative estimate the percentage of big game infected with trypano- 

 somes pathogenic to man and domestic stock may at Nawalia (LuangT\-a Val- 

 ley) be placed at 50, and at Ngoa (Kongo-Zambezi watershed) at 35. At 

 Nawalia G species of trypanosomes were isolated from game and domestic 

 stock, viz. Tnjpanosoma rhodesiense, T. vivax, T. nanum, T. pecorum, T. mont- 

 gomcryi, and T. multiforme; whilst at Ngoa 5 species were found, viz, T. rhode- 

 siense, T. vivax, T. nanum, T. pecorum, and T. tragelaphi.'' 



" The results of examination of over 400 monkeys, wild rats, and mice were 

 invariably negative." 



Tubercle bacilli in the circulating blood of bovines artificially infected 

 with pure cultures of the tubercle bacillus, W. Binder (Berlin. Tierdrztl. 

 Wchnschr., 29 (1913), No. 29, pp. 513-519).— The investigations here reported 

 were made with 9 animals which had been treated with pure cultures of the 

 bovine tubercle bacillus for some other experiments. For detecting tubercle 

 bacilli in the circulating blood the Stiiubli-Schnitter method and the Kurashige 

 modification thereof were used, but the former method is preferred. 



The author concludes that tubercle bacilli do occur in the circulating blood 

 of tuberculous bovines, contrary to the findings of Schroeder and Cotton 

 (E. S. R.. 22, p. S3), although in none of the cases were very many organisms 

 found in a microscopic field. In the severest cases only 3 to 5 organisms per 

 field were noted. When intravenously injected the bacilli were noted in the 

 blood from 3 to 11 days later, then they disappeared and reappeared after 17 

 to 30 days. While it was easier to detect the tubercle bacilli in severe cases, 

 no prognostic significance, the author says, can be attached to the finding of 

 tubercle bacilli in the circulating blood. 



Tubercle bacilli in the circulating blood, E. Rosenberg (Miinchen. Med. 

 Wchnschr., 60 (1913), No. S. pp. J/OJf, 1,05; ahs. in Dent. Med. Wchnschr., 39 

 (1913), No. 11, pp. 522, 523). — In the blood of nearly all cases of tuberculosis 

 (pulmonary and surgical cases in man) acid-fast bacilli resembling the tubercle 

 bacillus were noted. Tlioy were never found in the blood of normal subjects. 



The detection of tubercle bacilli in the circulating blood, E. Kahn (Miin- 

 chen. Med. Wchnschr., 60 (1913), No. 7, pp. 3^5, 3.',6; ahs. in Berlin. Tierdrztl. 

 Wchnschr., 29 (1913), No. 22, p. 402).— Attention is called to the fact that a 

 mere microscopical examination of the blood is not an adequate means for 

 detecting the presence of tubercle bacilli in the circulating blood. The animal 

 test is the most certain method. 



Chemotherapy of tuberculosis with gold preparations, A. Feldt (Deut. Med. 

 Wchnschr., 39 (1913), No. 12, pp. 549-551; ahs. in Berlin. Tierdrztl. Wchnschr., 

 29 (1913), No. 22, p. 402). — The preparations used were combinations of can- 

 tharidin and gold, and for their preparation cantharidinethylendiamin, which 

 is a nontoxic preparation, and gold cyanid were employed. Cantharidin, which 

 is capable of producing a reaction in tuberculosis and in other inflammatory
