Acarian eczema in dogs, I-. Schehex {Berlin. Ticrdrztl. ]\'clin.<irhr., Jft03, Xo. 31, 

 pp. 48-, 4SS). — In the trratiiieiit nt this disease the author had good results from the 

 use of a 4o per eeut sohition <>f nitrate of silver, which was used as a wash upon 

 affected parts. 



Necrosis and the necrosis bacillus, W. Ernst {Monatuh. Prakt. Tier., 14 

 (190.!), Xn. 5, pp. 19S~2 i'S, figfi. 14). — The necrosis bacillus {Sfreptolkru: necrophora) 

 is described as being of almost ul)iquitous occurrence and as producing a great variety 

 of pathological lesions, according to the part or organ affected. Numerous experi- 

 ments were made by the author in cultivating this organism, studying its morphol- 

 ogy, and in inoculating small anitnals. It was found that the necrosis bacillus grows 

 luxuriantly in nutrient media which remain moderately soft at the ordinary temper- 

 ature of the laboratory incubator, and that the organism grows well also in milk and 

 Martin bouillon. Growth takes place between temperatures 36 and 40° C, but most 

 rapidly at 39° G. There are no fiagella on the necrosis bacillus and no movement is 

 to be observed. The organism is very pathogenic for mice and rabbits and less so 

 for birds, rats, guinea pigs, and cats. In hogs, sheep, and cattle only local processes 

 are developed as a rule. Feeding experiments with hogs and sheep failed to pro- 

 duce infection. 



Angiomatosis capillaris maculosa in the liver of ruminants, Stroh 

 {^Vonatsh. Prakf. Tier., 14 {1903), Xo. 3-4, pp. 133-187, figs, i^).— The pathological 

 lesions produced by this disease are described by the author in great detail. As a 

 result of numerous obsiervations and experiments it is concluded that this disease is 

 ])eculiar to the liver of ruminants. The pathological foci in the liver arises as a rule 

 in consequence of the compression of the abdominal portion of the posterior vena 

 cava. The disease occurs in the liver of cattle of all ages and also in sheep. As a 

 rule the pathological process seems to have only a limited existence and gradually 

 becomes checked. 



The sequelae of contagious coryza, J. J. Kofler {Monatsh. Prakt. Tier., 14 

 {1903), Xo. 2, pp. 7-?-<?5).— According to the author's experience contagious coryza 

 ma}' be complicated with a number of diseases, such as staggers, embolic pneumonia, 

 iritis, petechial fever, etc. 



The giant Trypanosoma discovered in the blood of bovines, A. Lingard 

 {CciilhJ. Bakt. n. p(tr., 1. Alt., Ori;/., 34 (1903), Xo. 2, pp. 234-238, pi. 7).— Notes are 

 given on the giant Trypanosoma discovered in the blood of rattle during an investi- 

 gation of surra. 



Trypanosomes, with special reference to surra, W. G. Bowers (Jour. Camp. 

 Med. and Vet. Arch., 24 (1903), Xo. 2, pp. 65-71). — The author mentions the charac- 

 teristic features of various species of pathogenic Tryjianosoma and describes in con- 

 siderable detail the organism of surra. This disease is believed to be transmitted in 

 the Philippines through the agency of Sloniuxyn calcitruns. In the treatment of surra 

 some success has 1)een had with the administration of arsenic Ity intravenous method. 



The reproduction and development of trypanosomata in the blood of ani- 

 mals affected with surra, A. Br.\ler (Berlin.. Tieriirztl. Wchnschr., 1903, Xo. 40, 

 ■pp. (Jl.J-tJli;, figf. 7). — According to the author's investigations trypanosomata of 

 surra form spores in blood in which the parasites are present in large numbers. 

 The author observed a union of the trypanosomata by their blunt ends. At certain 

 stages the blood organisms assume forms and actions which greatly resemble those 

 of bacteria. Division processes are observed in spores associated in large colonies. 

 As soon as the blood parasites reach a diameter of \ to i that of the red blood 

 corpuscle they manifest amceboid movements ami attack the red blood corimscles, 

 causing lesions which are easily demonstrated. 



A new Trypanosoma and the disease caused by it, A. Tiieii-eu (Jour. Comp. 

 Path, and Titer., 10 (1903), Xo. 3, jip. 193-210, pi. 1, fig. i). — In studying a disease 

 of cattle in South Africa which was l)elieved to be identical with what has previously
