from the acute stages of rabies and which was in a persistent cachectic condi- 

 tion. As far as could be judged from external symptoms, there was no reason 

 to diagnose the case as rabies. Inoculation experiments, however, with ma- 

 terial ol)tained from the brain showed conclusively that the dog was affected 

 With that disease. 



The function of the spleen in trypanosomiases, A. IjAVi:hax and A. Thiroux 

 (Coinpt. Rend. Acad. Sci. [Paris}, l.'iS {1901), No, 5, pp. 2.95-2.97).— Additional 

 evidence was obtained that in all eases of infection the trypanosomes disappear 

 rapidly at the crisis of the disease, at least in cases which recover. This 

 destruction of the trypanosomes, however, occurs in animals from which the 

 spleen has been removed in the same maner as in normal animals. Apparently, 

 therefore, the sjileen has nothing to do with the dis.-ippearauce of the 

 trypanosomes. 



The role of the spleen in trypanosomiases, A. Massaglia (Gompt. Rend. 

 Acad. Sri. [Paris], J.'/.J (1907), Xo. l), pp. 572-575). — The experiments outlined 

 in this paper relate largely to the progress of surra in dogs from which the 

 spleen had been removed, and to a study of the behavior of the trypanosomes 

 under the influence of the spleen. It was found that trypanosomes obtained 

 from the spleen do not differ in any respect from those which were taken from 

 other organs or from the blood. The virulence of trypanosomes in the spleen 

 did not disappear after death with any greater rapidity than that of those in 

 the blood. In dogs from which the spleen had been removed surra developed 

 in the same maimer as in normal animals. 



Surra in Indo China, H. Sciiein (Ann. In.sl. Pasteur, 21 {1907), Ao. 9, pp. 

 739-752). — The various trypanosome epizootics studied by the author in Indo 

 China have all been due to the same parasite. The infection has come from 

 various centers where surra is known to prevail. The buffalo does not become 

 vaccinated by one attack of surra and even after two attacks may still be a 

 dangerous carrier of virulent parasites. Cattle and buffaloes are considered as 

 the chief agents in the transmission of this disease. 



In protecting hcrses against surra better drainage and other sanitary arrange- 

 ments are reconunended as well as separation of horses from all suspected cattle 

 and buffalo. Albuminuria is a constant symptom of the disease at its crisis. 

 The saliva of diseased horses is not virulent. The direct action of sunlight 

 appears to have no effect upon the development of surra, but anthrax and other 

 forms of septicemia cause the disappearance of trypanosomes in the blood. 



Trypanosomiases of the Upper Niger, A. I.avkuan {Coinpt. Rend. Acad. 

 Sci. [Paris], l'i5 (1907), Xo. 5. pp. 29.^-295) .— Cuttle which had been inoculated 

 with the virus of the disease kncnvn as dabab were found, upon recovery from 

 inoculation, to be completely refractory to Trupanosonia soudancnsc. It is be- 

 lieved therefore that this is probably the pathogenic organism of dabab. 



The use of arsenious acid in trypanosomiases, A. Laveran and A. Tiiirou.x 

 {Compt. Rend. Acad. Sci. [Paris], 1J,5 {1907), No. L'l, pp. JSi-JS//).— In the 

 experiments reported by the authors the amount of arsenious acid found in the 

 blood or lymph after 24 hours was quite insufficient to check the multiplication 

 of the trypanosomes. Api)arently the arsenious acid which has not been elimi- 

 nated from the body at the end of 24 hours is already fixed in the tissues. It 

 is suggested, therefore, that in order to obtain any germicidal results from 

 arsenic it should be administered at shorter intervals. 



The means of the dissemination of tuberculosis in animal experiments 

 with particular reference to the bronchial glands, F. OEnLECKEB {Tuber- 

 Jculosc Arb. K. Clsndlitsaint., 1907, Xo. 7, pp. 65-102). — Following upon the infec- 

 tion of the iliac glands, the spleen and its portal gland soon become involved 

 with the tuberculous infection. It is to be suitposed that after infection of the
