are found in South Africa and many of them have been suspected of carrying malaria. 

 The author offers a critical review of the literature of this subject. Notes are also 

 given on anthrax and strangles. Detailed directions are given for the application of 

 the most important methods for destroying mosquitoes and the tsetse fly and for 

 keeping these insects out of stalls and stables. 



Chronic tuberculosis in the horse, M. Schwammel {Ztschr. Tiermed., 4 {1900), 

 No. 2-3, pp. 182-186). — The author reviews briefly the literature on tuberculosis in 

 the horse. Detailed notes are given on a post-mortem examination of a case of 

 chronic tuberculosis in the horse. I^ general the post-mortem appearances were 

 similar to those of bovine tuberculosis. The disease was readily distinguishable from 

 glanders by the fact that the characteristic lesions of glanders were absent. The 

 horse had been kept on an estate where from 60 to 80 per cent of cattle were infected 

 with tuberculosis. Some of the cattle were draft oxen and had been allowed to 

 stand temporarily in the same stall where the horse was kept. It is believed that 

 the disease was transmitted in this manner. 



The hyphomycetous nature of the glanders bacillus, H. Coxradi (Ztsc/ir. 

 Hyg. u. Infcctiomhmn'k., 33 {1900), No. 2, pp. 161-177, pis. ;i').— The author gives a 

 review of the Uterature on the subject of the morphological structure of the glanders 

 bacillus. From a bacteriological study of the organism of glanders, the author 

 believes that it does not belong properly to the bacteria, since it was shown that the 

 normal developmental processes of the organism lead to stages which show a mono- 

 podial branching and false branching similar to that of Cladothrix. The organism of 

 glanders is believed by the author to be closely related to the Actinomyces group fungi. 



Pathological-anatomical studies of the Borna disease, H. Dexler [Ztschr. 

 Tiermed., 4 {1900), No. 2-3, pp. 110-121, figs. 3). — An examination of the cervical 

 region of the spinal cord in cases of this disease disclosed the presence of a recent 

 inflammation of the membranes which had progressed for some distance into the 

 substance of the brain and spinal cord. From a careful study of cases of the Borna 

 diseace, the author considers as diagnostic. certain structural changes in the central 

 nervous system, especially in the substance of the cervical region of the spinal cord, 

 the piamater of the hemispheres, the lateral plexus of the cerebellum and in the 

 cortex of the cerebrum. The author concludes that the Borna disease should be 

 characterized as a meningo-encephalitis and myelitis. 



The etiology of rabies, S. v. Ratz {Monatsh. Prakt. Thlerh., 11 {1900), No. 9, 

 pp. 402-410). — The author gives a critical review of the literature relating to the 

 230ssible hereditary transmission of rabies. From the brain of a pregnant cow which 

 had died of rabies, material was taken for the inoculation of rabies with the result 

 that the characteristic symptoms of rallies were produced in the experimental animals. 

 Material taken from the foetal brain failed to produce rabies in rabbits. The author 

 made a number of experiments in inoculating animals with material from the brain of 

 dogs which had died of rabies. The dogs were allowed to remain buried for varying 

 periods before the material was taken from the brain for inoculation. The results 

 of these experiments indicate that the virus of rabies is present in the brain of dogs 

 which have been buried from 14 to 24 days. Putrefaction, liowever, had the effect 

 of weakening the virulence. 



Experiments on the action of Epicarin in the treatment of mange of dogs, 

 Regenbogex {Monatsh. Prakt. Thierh., 11 {1900), No. 4, PP- 14-'^-149) . — Experiments 

 made by the author for the purpose of determining the value of epit;arin in the treat- 

 ment of dog mange gave the following results: Epicarin given internally in 0.5 gni. 

 per kilogram of body weight is not poisonous. Isolated Sarcoptes sqnamiferus and 

 Acarus folliculorum were killed much less quickly by alcoholic solutions of epicarin 

 than by solutions of cresol preparations. The treatment of mangy dogs was not 

 satisfactory, since considerable time and trouble were involved in the application of 

 the method and the results were uncertain.
