 Infection by the name "bovine tuberculosis." In anim. 11 a< in 



of Cattle. man the direct cause of this disease is thr tubercle bacillus. 

 Bovine tuberculosis is prevalent in nearly every country. The 

 symptoms of the disease are much likr those in man. They 

 begin with relatively slight functional disturbances. The way 

 the germ of tuberculosis is transmitted from animals to inen. 

 and also from men to animals, has already been explained. 

 The contagion, or rather the propagation, of the disease amoni: 

 animals takes place in various ways: First, by drop infection. 

 that is to say, little particles which are expelled durini: the 

 cough. 'Secondly, by the . discharge from the lungs, or a No 

 from the glands of the throat, coughed up in the ordinary way. 

 Thirdly, through tuberculous matter coming from the bo\\ 

 Fourthly, through ma coming from thr sexual or- 



(vagina and uterus). Fifthly, through the milk if the udder 

 is tuberculous, or if the whole body of the animal is invaded 

 by the disease. Finally, the disease may be directly transmitted 

 from the tuberculous cow to the calf. 



As to the frequency of the various ways in which the con- 

 tagion takes place and the best methods of prrvmtion, tin- 

 author does not Iwlievo that he can do better than to refer any 

 one interested in the subject to the very "Practical Sugges- 

 tions for the Suppression and Prevention of Bovine Tuber- 

 culosis," issued by Dr. Theobald Smith, of the Bureau of Animal
