The bacteriolytic action of gland extracts on tubercle bacilli, A. E. Pobteb 

 (Jour. Hyg. [Cambridge'^, 16 {1911), No. 1, pp. 55-65). — Lung extract was 

 found to be the least bactericidal, while pancreas extract was found to be the 

 most powerful. The extracts of liver, thymus, and lymphatic glands were all 

 strongly bactericidal. Suprarenal gland, pig and cat spleen, human and cat 

 kidney, human and ox brain, ox thyroid, cat lung, ox bone marrow, and ox 

 pituitary gland extracts were all found to be bactericidal to a lesser degree. 

 A human skin extract was examined for bactericidal properties and found to 

 be exceptionally rich in esterases. It is noted that this sample of skin extract 

 bears out the relationship between lipolysis and bactericflysis of tubercle becilli, 

 since the extract was extremely bactericidal. No difference was observed 

 between the bovine and human tubercle bacilli in susceptibility to any of the 

 gland extracts examined. 



" Other acid-fast bacilli, though on the whole less susceptible than tubercle 

 bacilli to the influence of these extracts, were bacteriolyzed by them. They 

 were also killed by one lung extract (pig's) which contained an unusually large 

 amount of olein lipase and which had no effect on tubercle bacilli." 



The data are presented in tabular form. 



On the claimed differential characteristic of the avian tubercle bacillus, 

 A. RocHAix {Compt. Rend. Soc. Biol. [Paris], 80 (1911), No. 12, pp. 510, 511).— 

 Data are submitted from which the author concludes that the medium pre- 

 viously described,' consisting of agar with carrot juice, can not be used to 

 differentiate the avian from the human and bovine tubercle bacillus as has been 

 recently claimed by Ranjel de Morals.* 



Vaccination ag'ainst bovine tuberculosis, A. Bbuschettini (Rev. Path. 

 Comp., No. ISl (1911), pp. 5, 6; abs. in Vet. Rev., 1 (1911), No. 3, pp. 295, 

 296). — A vaccine is described which has been prepared by injecting virulent 

 bovine bacilli (previously washed in a mixture of alcohol and ether to remove 

 the fat) into the pleural cavity of rabbits. After 48 hours the bacilli are col- 

 lected, carefully ground with quartz sand, and emulsified in an agitator with 

 0.5 per cent phenol solution. After the addition of ether the mixture is filtered 

 through cotton and preserved under toluol in a refrigerator. 



Eight calves were vaccinated with the preparation, five subcutaneously and 

 three intravenously. Six months later the calves were inoculated with tubercle 

 bacilli, four of them with the culture and the other four with an emulsion of 

 mammary tuberculosis extremely rich in bacilli. The results obtained were so 

 satisfactory that a practical test on a large number of animals has been 

 recommended. 



Tuberculosis in farm animals, C. L. McAbthur (Arkansas Sta. Bui. 136 

 (1911), pp. 3-15, figs. 5). — This bulletin briefly describes the disease in cattle, 

 swine, and fowls ; the tuberculin test ; and the duration of life of the tubercle 

 bacillus outside of the animal body. 



Managing' a tuberculous herd (Iowa Sta. Bui. 112 (1911), pp. 19-90, figs. 

 6). — This bulletin consists of two parts. 



I. History of the tuberculous herd at Iowa State College since 1909, W. H. 

 Pew (pp. 79-86). — This material has been essentially noted from another source 

 (E. S. R., 37, p. 379). 



II. Plans for the control and eradication of tuberculosis, C. H. Stange (pp. 

 86-90). — The author here briefly outlines the methods which have been pro- 

 posed for the control and eradication of the disease and gives the recommenda-
