Trypanosomiasis observed in horses of the Sahara, Rakdot {Rec. Ilyg. ct 

 Med. Vvt. Mil.. 10 (liH)!)), /). o.li ; (ibs. in Rcr. <lrn. Mid. Vet., 15 (1910), No. 

 110, pp. 103, lO'i). — A trypanosomiasis of camels and horses is i-eported to occur 

 in South Orau. In the camel it runs a chronic course, but is acute in the horse, 

 to which it proves fatal in a large percentage of cases. 



The transmission of Trypanosoma equiperdum, H, Siebeb and K. (tONDkr 

 {.irch. Krhitfx u. Tropcn lhj(j., 12 {1908), No. II, p. 6V/6; ahs. in Join: Trop. 

 Vet. Set.. // {1909), No. J,, p. 5cS.'/).— The authors state that they apiiarently suc- 

 ceetled in transmitting dourine from an infected to a healthy animal by means 

 of Stomo.njfi ealeilrans. There did not seem to be any development of the 

 trypanosome in the fly, the transmission ai)pearing to be purely mechanical. 

 Attempts to transmit the trypanosome from an infected to an uninfected rat 

 resulted negatively. 



Contribution to the study and etiolog'y of souma, (4. Pecaud (BiiL Hoe. 

 Path. Exot., 2 {1909), No. 9, pp. 530-532; ahs. in Sleeping Sieknefis Bur. [Lon- 

 don] Bui. 12, p. .'i51). — Fourteen specimens of (ilossina palpnlis were collected 

 on the banks of a lagoon near Porto Novo where tliere was a small herd of 

 cattle in 3 members of which Tnjupnosoina cnzalboui had been found. The 

 flies were put on a healthy sheep on 3 successive days, and 14 days after the 

 first bites T. eazalboui was found in the sheep. The author now believes that 

 distant transmission of T. eazalboui is effected by tsetse flies and inunediate 

 transmission l)y Stomoxys and tabanids. Evidence was obtained that Sto- 

 moxys transmitted the disease in the stable and an appended note adds that a 

 recent observation shows the same to occur with T. diniorphon. 



Report of the results of investig'ations in German East Africa in 1906-7 

 by the German Sleeping" Sickness Commission, R. Kocii, M. P>eck, and F. 

 Kleine {Arb. K. asndhtmnit.. 31 {1909), No. 1. pp. 320, pis. 5, figs. 100, eharts 

 65, maps 6; abs. in Sleeping Sickness Bur. ILondon] Bui. 11, pp. Ji20-.'i29). — 

 The chapters on etiology and on general preventive measures are by R. Koch ; 

 those on diagnosis, symptoms, and treatment, and also the account of cases, are 

 by M. Beck; while part of the chapter on preventive measures is by Kleine. 

 The distribution of Glossina palpalis and of sleeping sickness and the route 

 followed are shown on maps. 



[How tubercle bacilli enter the bodyl. P. Chausse {Ree. Med. Vet., 86

 {1910), No. 110, pp. 89-91). — A critical review of the sub.iect in which it is con- 

 cluded that the bacilli enter the body largely by inhalation. 



A contribution to the study of the vaccination against tuberculosis of 

 cattle by Klimmer's method, E. Glockner {Berlin. Tierdrztl. Wchnschr., 25 

 {J909), No. 16, pp. 292-29-i; abs. in Bui. Inst. Pasteur, 1 {1909), No. 15, pp. 659, 

 660). — Of the several methods of vaccinating cattle against tuberculosis, the 

 author prefers that of Klinnner. In this method tubercle bacilli of the human 

 type which have been attenuated by heating to from 52 to 53° C. and bacilli 

 rendered avirulent by passage tlirough the salamander are used. Tlie author 

 vaccinated, by single injections 23 young animals of which 4 had reacted to 

 tuberculin. 



After a year in contact with cows suspected of tuberculosis, one of the ani- 

 mals which had not reacted was killeti and found to be free from the disease. 

 Two of tliose which liad reacted to tuberculin previous to vaccination were 

 killed at the same time and lesions found which had completely calcified. The 

 author concludes that this vaccine not only has an immunizing but also a cura
