species and 3 others {Piroplasma higcmmum,, P. mutans, and Spirochceta 

 theileri) which can be transmitted through the inoculation of blood and by ticks, 

 occur in South Africa. 



On the development of piroplasma in the different organs, R. Gondeb 

 (Ann Transvaal Mns., 2 (19 JO), No. 2, pp. Jf9-52, ph. 3).— The author finds Piro- 

 plasma parvum and P. inutans to show differences in their cycle of development 

 as well as in their pathogenic effect. The blue bodies are said to represent a 

 certain stage in the development of P. parvum which corresponds to the shizog- 

 ony in the cycle of the malarial and other parasites. 



The life history of Trypanosoma dimorphon, E. Hindle (TJniv. Cal. Pubs., 

 Zool., 6 (J 909). Xo. 6, pp. IZl-lJ,',, pis. 3, fig. 1).—A report of studies made of 

 T. dimorphon, in which rats and guinea pigs were used. 



Bacteriological diagnosis of anthrax and symptomatic anthrax in veteri- 

 nary inspection practice, Foth (Arch. Wiss. u. Prakt. Tierheilk., 36 (1910), 

 Suj)., pp. 93-107). — A discussion with regard to the relation of the bacterio- 

 logical to the clinical and anatomical findings in cases of anthrax and symp- 

 tomatic anthrax. 



Anticharbon vaccination with very virulent bacteria and in a mixture 

 with pyocyaneus, J. D'Agata (Ann. Inst. Pasteur, 2h (1910), No. J/, pp. 330- 

 336). — These tests were made with sheep and rabbits and bouillon cultures of 

 pyocyaneus and anthrax bacteria. Some of the tests were conducted with the 

 culture of anthrax bacilli alone, and others with a bouillon culture of anthrax 

 and pyocyaneus bacteria. The tests showed that the anthrax bacillus when 

 cultivated with pyocyaneus bacilli lost their virulency for rabbits. 



[Immunizing tests with " farase " and horses and other animals against 

 glanders], F. Bautz and S. Machodin (Berlin. Tierdrztl. Wchnsclir.,26 (1910), 

 No. 12, pp. 261f-266; abs. in Zentbl. Allg. u. Expt. Biol., 1 (1910), No. 7-8, p. 

 236). — These tests were conducted with Levy's "farase" (E. S. R., 19, p. 887; 

 20, p. 10S5), and showed its harmlessness when used for cats, guinea pigs, and 

 foals, and pi'oduced a fairly lasting imnumity. 



Studies in regard to the etiology of rabies, J. Koch and P. Rissling (Ztschr. 

 Ilyg. II. Infcktioiiskrank., 65 (1910), No. 1, pp. 85-112, pis. 3).— The material 

 employed consisted of the brains of 50 dogs artificially infected, and further, 

 of the brains of dogs sent to the laboratory for diagnosis. Some bovine brains 

 were also examined. 



The authors were able with the aid of Heidenhain's hematoxylin stain to note 

 cocci-like formations in the gray substance of the horn of Ammon. Negri bodies 

 were either absent or only sparingly present. In various instances many of 

 the above-mentioned cocci bodies could be noted in the ganglion cells and beside 

 the Negri bodies. The gray matter of the brain cortex also was profusely 

 studded with these dot-like bodies. In the degenerated ganglion cells of the 

 brain and spinal cord, particularly in the cervical and lumbar region of the 

 cord of the animals in early and late stages of the disease " endocellular en- 

 closures" could be detected with the hematoxylin stain. These appeared as 

 small mouococci. diplococci, or rods and had the appearance of the inner 

 formations of the Negri bodies. The author believes these cocci-like bodies to 

 be parasites, and that the Negri bodies are only reaction products in the bom 

 of Ammon. 



Facts and problems of rabies, A. M. Stimson (Pub. Health and Mar. Hosp. 

 Serv. U. 8., Hyg. Lab. Bui. 65, pp. 90, pis. J,).— This bulletin reviews the pres- 

 ent state of our knowledge of rabies, and includes the history, geographic dis- 

 tribution, etiology, symptoms, diagnosis, immunity, treatment, and suppressive 

 measures.
