of from one to n fllni to 6 or 10 to a field for a day or two, then disappearing 

 for 6 or 7 days to reappear again during a febrile paroxysm." The disease is 

 differentiated from surra, mal de caderas, and dourine by morphology, animal 

 reactions and symptomatology. It is thought possible that the infection may 

 be the same as that said to occur in the interior of Colombia, known as der- 

 rengadera. 



The author has failed to find trypanosonies in the blood of several native 

 horses examined, but these were found in all the affected animals. He exi)resses 

 the thought that the infectious anemia which occurs in this country may be a 

 trypanosomal disease in which tryi)anosomes are very sparse in the peripheral 

 blood, as in dourine. but in which they may luxuriate in a tropical climate. 



Investigations of dourine in eastern Prussia, E. Frohner (Monatsh. Prakt. 

 Ticrhcilk., 20 {1909), Nos. 9-10, pp. 3So-J,lJ,, fi[)s. 5; 11-12, pp. J,Sl--'i9.3 ; ahs. in 

 Rev. Gin. Mid. V6t., 15 (1910), No. 11 J,, pp. 338-340).— Studies of 4 cases of 

 chronic dourine in horses received from Rastenburg, Prussia, are reported ui)on. 

 Examinations of the blood and tissues resulted in the finding of trypanosonies in 

 the blood of l>ut one of the horses. 



A physico-chemical investigation of equine piroplasmosis, W. Frei {Ztschr. 

 Infektionskrank. u. Hyg. Haustiere, 7 {1910), No. 1-2, pp. 105-1. W, pis. 3).— A 

 contribution from the Transvaal Bacteriological Institute at Pretoria. 



A case of hydrophobia in a Senegal dog, L. Teppaz (Bui. Soc. Path. Ejrot., 

 S {1910), No. 6, p. 351). — The author reports what is thought to be the first 

 case of this affection to occur in Senegal. 



The dog's medical dictionary, A. J. Sewell {London, 1907, 2. cd., rev., pp. 

 250, i)ls. 11, p(js. 21). — An encyclopedia of the diseases, their diagnosis and 

 treatment, and the i>hysical (leveloimiont of the dog. 



Further observations with von Behring's protective vaccination and Tau- 

 ruman vaccination, A. Eber {Centbl. Bakt. [etc.], 1. Abt., Orig., 52 {1909), 

 No. 3, pp. 389-J,06; ahs. in Centbl. Bakt. [etc.], 1. Abt., Ref., 1,6 {1910), No. 13- 

 14, pp. Ji35, -'i36). — The author reports results with bovovaccine in practice. He 

 is still of the opinion (E. S. R., 19, pp. 784. 1083) that a positive tuberculiu 

 reaction three-quarters of a year after the last vaccination has the same signifi- 

 cance as the same results from a herd which is tuberculous. On the other hand, 

 a negative finding with the tuberculin test at this time is no absolute proof that 

 the herd is not tubercular. Witli 14 bovines immunized according to von 

 Behring the results were controlled by autopsy, and it was found that 10 were 

 free from tuberculosis, while 4 wei'e more or less tuberculous. From this he con- 

 cludes that von Behring's method in itself is no certain i)rotection against latent 

 infection by the tubercle bacillus. 



The results with Tauruman vaccination, while not conclusive, indicate that 

 this vaccine also does not confer a lasting immunity in bovines. 



On the occurrence of a form of fowl-septicemia in Calcutta, G. C. Chat- 

 TEKJKE {Centbl. Bakt. [rtc.]. 1. Abt., Orig.. 5', (1910). No. 1. pp. 1-1,, fig. 1).— 

 "The micro-organism, which was separated from fowls dying of an epizootic 

 disease occurring among the animals in the Medical College Laboratory, is 

 found to have characters like that found in fowl septicemia observed in Europe 

 and belongs to the Pasteurella group of micro-organisms. It differs from the 

 Bacillus oiiscpticKs in certain minor points which suggest that it is a local 

 variety of the organism. A vaccine was prei)ared from the organism which was 

 found to protect healthy fowls from catching the infection." 



About passive immunity in fowl cholera, O. Schobi. (Centbl. Bakt. [etc.], 

 1. Abt., Orig.. 51 [I9i)9). No. 3, pp. 2S5-2S9). — In order to establish whether 

 or not by vaccinating with serum-i)acteria active inuuunity is obtained, the 

 author vaccinated mice and from the results concludes that mite thus treated
