VETERINARY MEDICINE, 85 



T. pecaudi, T. dimorplion, and T. congolense, in which the immunity to T. diinor- 

 phon still existed 22 months after recovery from the T. dimorplion Infection. 

 The serum of such sheep and goats keeps its activity for a long time when used 

 in admixture with virulent blood. In one case the serum of a sheep was active 

 2 years and 6 months after recovery from T. dimorplion infection. Attention is 

 called to the fact that in consequence of this resistance of sheep and goats and 

 the long lasting immunity which a first attack often confers on them, the rear- 

 ing of these animals may succeed in countries where trypanosomiasis is endemic. 



A trypanosome disease of the camel in German Southwest Africa, 

 Reinecke (Ztschr. Veterindrk., 23 {1911), No. 1, pp. 1-12; ais. in Sleeping 

 Sickness Bur. [London^ Bui., 3 {1911), No. 28, p. 263). — The trypanosomes 

 contained in smears from 5 camels at Kalkfoutein and from 2 camels at 

 Gochas were similar to Trypanosoma brucei and T. evansi, corresponding with 

 the latter in almost all points. The disease is thought to be identical with 

 the variety of surra, known as " mbori." Transmission experiments with 

 Stomoxys and Hippobosca were unsuccessful. 



A bibliography of 31 titles is appended. 



The etiological diagnosis of tuberculosis, W. C. Wilkinson {Brit. Jour. 

 Tuberculosis, 4 {1910), No. 1, pp. 40, ^i; ahs. in Internat. CentM. Gesam. 

 Tuberkulose Forscli., 5 {1911), No. 4, p. 204). — "Koch's tuberculin test is 

 simple, safe, and trustworthy. Yon Pirquet's is much superior to Calmette's, 

 but should only displace Koch's when there is much fever. The agglutination 

 test is worthless. Wassermann's reaction in tuberculosis requires great skill 

 and extensive laboratory equipment. The opsonic test is only mentioned to be 

 condemned unreservedly." 



The technique of determining the opsonic index, H. Reitee {Deut. Med. 

 Wchnschr., 36 {1910), No. 52, pp. 2426-2428; abs. in Centbl. Bakt. [etc.'], 1. 

 Abt., Ref., 49 {1911), No 1-2, p. 60).— A detailed description of the precedure. 

 Besides Wright's in.struments, other handy apparatus is described. 



An improved antiformin method for tubercle bacilli, Lorenz {Berlin. Klin. 

 Wchnsehr., 48 {1911), No. 3, pp. 118, 119; abs. in Ztschr. Tuberkulose, 17 

 (1911), No. 3, p. 289).— This is a modification of the Uhlenhuth method, which 

 consists of boiling the sputum antiformin mixture after it has been completely 

 homogenized. 



Precipitation of an aqueous tuberculin with the serum from tuberculous 

 subjects, S. Aeloing and P. Courmont {Lyon Med., 114 {1910), No. 18, pp. 

 968-972; abs. in Internat. Centbl. Gesam. Tuberktilose Forscli., 5 {1910), No. 

 2, pp. 69, 70). — The authors point out that they were able to precipitate an 

 aqueous decoction of a homogenous culture of the tubercle bacillus with human 

 and animal serum from normal and tuberculous subjects. According to the 

 authors, the reaction is not an agglutinating one nor is it a specific reaction 

 for tuberculin. 



Tuberculosis in dogs, E. Schbum (Uber Hundetuberkulose. Inaug. Diss., 

 Vniv. Bern, 1910, pp. 62; rev. in Ztschr. Tuberkulose, 17 {1911), No. 3, p. 

 SOI). — After making a statistical study of the prevalence of tuberculosis in 

 dogs, the author tested dogs in regard to their receptiveness for tuberculous 

 infection. It was noticed that dogs are decidedly resistant toward the disease 

 and that this is irrespective of the type of bacillus used. 



In regard to immunizing against tuberculosis and the serum treatment 

 of tuberculosis, A. D. Pawlowsky (Ztschr. Tuberkulose, 17 (1911), No. 1, 

 pp. 1-26). — The author, after giving an extensive review of t^e literature on 

 the subject, details his own experiments with chickens, goats, guinea pigs, 

 horses, dogs, and rabbits.
