Experiments were made upon 3 tuberculous cows well fed upon a 

 wide ration, with the result that all 3 cows improved noticeably in 

 condition for a period of a year before jaelding to the general prog- 

 ress of the disease. 



The authors discuss the problem of checking tuberculosis l)y good 

 conditions of life and sanitation, the relation of l)ovinc tuberculosis to 

 })ublic health, the disposition of the Hesh of tuberculous animals, the 

 pathological anatomy and bacteriology of tuberculosis, the nature of 

 tuberculin, the ,s\'mptoms of tuberculosis, the value of the tuberculin 

 test, and the measures adopted in different countries for the suppres- 

 sion of this disease. An account is given of the regulations of the 

 State sanitar}^ board for the control of tuberculosis. Detailed reports 

 are given from herd owners on losses from tul>erculosis and on the 

 condition of inspected herds. 



The danger of spreading tuberculosis by means of milk, and 

 regulations for preventing this danger, Ki hnan {B<d!n. T'ltnirrdl. 

 Wchnschr.^ 1900^ JV^o. 5, x*P- 4^-52). — This article contains a critical 

 review of the literature upon the subject of tubercle bacilli in cows 

 milk. The commission of the German Dairy Union has recently 

 adopted resolutions, which are in the nature of a proposed bill, pro- 

 viding that all milch cows are to be inspected with reference to the 

 presence of tubercle bacilli in their milk. The milk of suspected cows 

 before being used must be heated to a temperature of .SS-* C. Every 

 cow which is found suffering from tuberculosis of the udder is to be 

 destroj^ed, and indemnity is provided ranging from $12 to $75. 



Experimental researches on symptomatic anthrax, E. Le- 

 CLAiNciiE and H. Vallee {Aim. List. FaHteur., IJ^. {1900)., Xo. ^, pp. 202- 

 ^^^). — The authors give a brief critical review of the literature relat- 

 ing to the micro-organism of symptomatic anthrax and discuss the 

 biology of this organism. The organism is strictly anaerobic, and it is 

 difficult to obtain pure cultures. The organism of S3^mptomatic anthrax 

 produces a toxin which is capable in itself of producing serious lesions 

 and death. The pure spores when deprived of the toxin are unable to 

 germinate or produce an infection even when introduced into the 

 tissues in large doses. The resistance of the organism to s3'mptomatic 

 anthrax depends upon phagocytic action. All conditions which pre- 

 vent or hinder phagocytosis are favora))le to infection. 



Experiments in the treatment of infectious mammitis of cows, 

 E. Zschokke {Lamho. Jahrh. ScJucels, 1.'^ {1900), jVo. 2., pp. o6-G^S). — 

 The author presents tables showing the percentage of infectious mam- 

 mitis as determined l)y the examination of milk samples, from 1894 to 

 1899. Tables show that the disease has become more frequent from year 

 to year. It is most common during the summer months, or during the 

 time when the greatest yield of milk is obtained. The d'sease appears 

 as an enzootic or epizootic. From 2 to 4 animals became infected one
