Further note on a cattle trypanosomiasis of Portuguese East Africa, W. 

 JowETT (Jour. Compar. Path, and Thcr., 24 (,1911), No. 1, pp.. 21-JfO, figs. 6). — 

 In this paper the author gives a more complete list of animal reactions of the 

 trypanosome, and reports upon the effect of passing the trypanosome throush a 

 series of rats, fly transmission experiments, and the action of certain chemical 

 agents on the trypanosome in vivo. 



The results indicate that the trypanosome may be transmitted mechanically 

 by one or other of the 2 genera of biting flies used in the experiment, namely 

 Hfematopota and Stomoxys. 



The transmission of African horse sickness to the dog by feeding, L. E. W. 

 Bevan {Vet. Jour., 67 (1911), No. 433, pp. 402-408, figs. 2).— The author here 

 reports observations and experiments which led to the conclusion that dogs 

 may become infected with African horse sickness in natural circumstances by 

 feeding on infective meat. 



Trypanblue in infectious anemia, A. W. Whitehouse (Amer. Jour. Vet. 

 Med., 6 (1911), No. 8, pp. 6S6-6S8). — One of 3 cases of infectious anemia 

 treated by the author with trypanblue recovered from the disease. In the case 

 of the animal that recovered the treatment consisted of the administration of 3 

 grains of trypanblue dissolved in 200 cc. of sterilized cold water, the solution 

 being raised to body temperature and injected at one application into the 

 jugular vein. 



Researches on trichinosis, M. Romanovitch (Compt. Rend. Soc. Biol. 

 [Paris]. 70 (1911) Nos. S, pp. 257-259; 9, pp. 339-341; 10, pp. 378, 379).— This 

 series of articles deals briefly with the experimental investigations of the action 

 of Trichinclla spiralis on the animal organism, its migration, and remedial 

 measures. The investigations led the author to conclude that the fever, ab- 

 scesses, and septicemia resulting in death as sometimes observed in human 

 cases are due to the microbes inoculated by the trichinae. 



Experiments with the intradermal test for tuberculosis in cattle, A. R. 

 Ward and G. S. Baker (Amer. Vet. Rev., 38 (1910), No. 2, pp. 184-193).— The 

 authors summarize their work as follows: 



" We have shown that 28 out of 30 reactions regarded by us as positive, 

 proved positive on autopsy. Of 4 considered questionable 3 proved positive on 

 slaughter. Two diagnosed as positive showed no lesions. Fifty-nine considered 

 as nonreactors proved negative on autopsy. Seven classed as negative reactions 

 showed lesions. The determination of a reaction calls for careful discrimi- 

 nating judgment on the part of the operator. With regard to the 7 cases of 

 tuberculosis which we failed to recognize by the test, we prefer to attribute 

 these to our inexperience rather than to a failure of the test. It is the only 

 test so far known that is applicable to range cattle on the range. In com- 

 paring the subcutaneous and intradermal tests we find a remarkably close 

 agreement in results. It requires no modification of the ordinary routine of the 

 animals, except that in range cattle it is necessary to confine them while making 

 the injection, and again 48 hours later to make the diagnosis. The time of 

 this confinement is insignificant. The intradermal test applied 5 days after 

 the subcutaneous test is not reliable." 



The eradication of cattle tuberculosis in the District of Columbia, R. W. 

 Hickman (U. S. Dept. Agr. Yearbook 1910, pp. 231-242).— This is a detailed 

 account of the manner in which the work of eradication of cattle tuberculosis 

 in the District of Columbia commenced November 29, 1910, was conducted, 

 together with the findings and results obtained. 



During the 4 months following that date 1,701 head were tested, of which 

 1,380 were apparently free from tuberculosis and 321 reacted and were 

 slaughtered.
