Note on examination of milk for tubercle bacilli, E. W. Hammond {Jour. Comp. 

 Med. and ]\'t. Arch., £1 {1900), No. 7, p. 59.5).— The author dihites milk which is to 

 be examined with an equal quantity of water. It is then centrifugalized for about 

 half an hour by means of an electric centrifuge. The sediment is then removed with 

 a fine pipette and a drop of this substance placed on a clean cover glass, dried, and 

 finally stained by the ordinary method: As a result of diluting milk with an equal 

 quantity of water, so little fatty material is thrown down in the sediment that it is 

 unnecessary to use ether or other reagents to dissolve out the fat. 



Tuberculin investigations {Landtmannen, 11 {1900), No. 25, pp. 402-403). — A 

 summary of the results from tuberculin injections with notes on the tuberculin prob- 

 lem in different parts of Sweden. Rather conclusive evidence is obtained in 1 case 

 of the transmission of tuberculosis from man to animals. 



The most important tuberculins; their preparation and differences, Baier- 

 MEiSTER {Arrh. TI'/.w. v. Prnli. Tliierh., 26 {1900), No. 4-5, jn'- 56»l-.5,'-^).— The author 

 gives a detailed discussion of the different methods of lareparation and different com- 

 position of about 30 kinds of tuberculin. Some tuberculins contain certain constitu- 

 ents of the media upon which the tubercle bacilli were grown while other tuberculins 

 are so prepared as to exclude all substances except the immediate products of the 

 tubercle bacillus. 



Measures to be adopted against outbreaks of anthrax in summer, W. W. 

 Flach {Landtmannen, 11 {1900), No. 20, pp. 309-315). — A general account of the 

 means of transmission of anthrax, together with a discussion of the sanitary measures 

 which should be adopted to prevent the spread of this disease. 



Means of preventing Texas fever, L. L. Lewis ( Oklahoma Sta. Rpt. 1900, pp. 

 26-28). — Popular notes on the etiology and methods of treatment for this disease. 



Blackleg: Its nature, cause, and prevention, A. T. Peters {Nebraska Sta. 

 Bid. 65, pp. 107-132, figs. 8.) — This l)ulletin contains a popular discussion of the 

 general subject of blackleg, including the symptoms and etiology of the disease, and 

 detailed directions for making preventive vaccinations against blackleg. 



A comparative study of the bacillus of malignant oedema and of blackleg, 

 E. Leclainche and H. Vallee {Ann. Inst. Pasteur, 14 {1900), No. 9, pp. 590-596). — 

 From inoculation experiments Avith these micro-organisms, the authors conclude that 

 there is a close biological connection between the two. The organisms may be dif- 

 ferentiated by the fact that in the serous fluid of specific oedema, in the peritoneum 

 of the guinea pig, the bacillus of malignant oedema appears in the long forms which 

 are regularly absent in the case of the bacillus of blackleg. The methods of immuni- 

 zation which are applicable to blackleg may also be used against malignant cedenia. 

 Immunization of an animal against blackleg does not imply an added resistance to 

 the l)acillus of malignant (edema. 



Pneumomycosis due to Aspergillus fumigatus, L. Pearson and M. P. Ravenel 

 {Jour. Comp. Med. and Vet. Arch., 21 {1900), No. 8, pp. 451-465, figs. 4).— T^^Q authors 

 give a critical review of the literature of this subject, together with notes on the cul- 

 tivation and description of the mold. A Jersey cow after giving evidence of a diseased 

 condition for a period of 6 months died, and upon examination the lungs were found 

 to contain large quantities of the hyplue and fruiting heads of Aspergillus fumigatus. 

 The lung most affected was exceedingly emphysematous and gave a crackling sound 

 on being rubbed. The cow did not react to the tuberculin test which was given 

 some time before death, but upon post-mortem examination 4 or 5 caseous calcareous 

 nodules were found in which the tubercle bacillus was present. It is suggested that 

 the infection by the mold may have interfered with the turberculin test. 



On carcinoma in cattle, L. Loeb and G. Jobson {Jour. Comp. Med. and Vet. 

 Arch., 21 {1900), No. 7, pp. 385-.394) .—In the 2,.514,446 head of cattle received at the 

 Chicago Stock Yards during the year 1899 49 cases of carcinoma were found. In all
