consequently, an apparent co-relation between these 3 diseases in horses, rattle, and 

 goats. 



Trypanosome diseases, R. Koch ( Berlin. Tierarztl. Wchnschr., 1904, No. 45, pp. 

 736-739, fig. 1). — Brief outlines are presented of the essential nature, symptoms, 

 etiology, and treatment of trypanosomiasis of rats, tsetse-fly disease, surra, and related 

 diseases in man and animals. 



The development of hemogregarines and trypanosomes, E. Brumpt | Compt. 

 Join!. Soc. Biol. [Pan's], 57 {1904), No. 27, pp. 165-167). — Brief notes are given on 

 the developmental stages of various species belonging to these groups. 



The trypanosoma of dourine and its inoculation into mice and rats, .1. 

 Rouget {Compt. Rend. Soc. Biol. [Paris], 56 {1904), No. 16, pp. 744, 745).— The 

 author had already found that the organisms of dourine when inoculated into white 

 mire multiply rapidly until the death of the experimental animals, winch occurs from 

 the fifth to the eleventh day. 



A further study was made of this matter, and the author believes as the result of 

 his experiments that the coexistence of several distinct trypanosomiases in Algeria 

 must he denied. It is believed that there is only one disease due to trypanosomes 

 and that the variation and symptoms are due to the resisting power of different 

 organisms and other varying conditions. 



The natural immunity of Cynocephalidae for trypanosomiases, A. Laveran 

 {Compt. Rend. Acad. Sci. [Paris], 139 {1904), No. 3, pp. 177-179).— This family of 

 primates has been noted as possessing a natural immunity for diseases caused by 

 trypanosomes. it was found that in rats affected with surra, nagana, and nial de 

 caderas the serum of species of Cynocephalidse in small quantities was sufficient t>> 

 cause the disappearance of trypanosomes in the blood for a number of hours. 



A disease in Somali land known by the name Aino, probably identical with 

 nagana of eastern Africa, E. Brumpt {Compt. Rend. Soc. Biol. [Paris], 56 (1904). 

 No. 14, t'/>- 673-677). — This disease was observed occurring spontaneously in camels 

 and mules. The author also made experiments on do>_ r s, zebras, ami species of 

 monkeys. The only tsetse fly observed in the Somali country was Glossina longipennis. 



The author made a study of the blood parasites of this disease as well as the symp- 

 toms produced in animals and concludes that the disease was identical with nagana. 

 in Abyssinia also the author made a study of the disease known there as horse plague 

 or ''lever." The course of the disease varies somewhat in different cases, hut an 

 examination of the blood and a study of the post-mortem pathology of the disease 

 convinced the author that it is identical with nagana. Notes are given on the 

 •_ r ei graphic distribution of the disease. 



Lesions produced in the nerve fibrillae by tetanus toxin, G. Marinesco 

 {Compt. Rend. Soc. Biol. [Paris], 57 {1904), No. 25, pp. 62, 63). — Considerable dif- 

 ference of opinion prevails at present among authors regarding the regularity ami 

 value of anatomical lesions found in animals or man dead of tetanus. 



The lesions observed by the author are quite variable as to form, intensity, and 

 localization. Nerve cells with black fibrillae remain intact or are only slightly 

 altered. The lesion varies in intensity according to the extent of granular disinte- 

 gration and fragmentary fibrilhe. The author determined during his experiments 

 and investigations that in the medulla oblongata of guinea pigs dead of tetanus there 

 are quite pronounced lesions of the nerve fibrillae and that these lesions are due in 

 a large part to the action of the tetanus toxin. 



Tetanus toxin, carmin, and betain, J. Rehns {Compt. Rend. Sue Biol. [Paris], 

 56 I 1904), No. 1~>, pp. 692, 693). — A careful biological and chemical study was made 

 of these stihstances and mixtures of them. 



Primary intestinal tuberculosis in children, X. Raw {British Med. Jour., 1904, 

 No. 2265, pi'. 1245, 1246). — Critical notes on tuberculosis in young children, together 

 with an examination of the conditions surrounding infection in a large number of cases.
