Bovine Tubekculosis. 121 



month, this distillery food has greatly impaired the animal's 

 sight and many of them are totally blind. If they remained long 

 enough, they would all be similarly affected. The lymphatic 

 glands at the base of the tongue are enlarged from twice to four 

 times their natural size and are generally the seat of an 

 abscess, which, from its size alone, must materially interfere with 

 the animal's deglutition. No doubt the glandular system 

 throughout the system has been similarly affected. If these ani- 

 mals were kept long enough under such conditions and forced to 

 partake of this food for a sufficient time, say, three or four 

 months, I have no doubt that the lungs, the liver^ the various in- 

 ternal organs, would become affected in the same way as the 

 hide, the eyes, and the glands at the base of the tongue; while 

 a condition due entirely to the nature of the food which the ani- 

 mal received, would, in all probability, be mistaken for lesions 

 of tuberculosis. 



Evident is it that bovine tuberculosis is a disease that is fre- 

 quently confounded with ills and conditions, of perhaps ap- 

 parently similar manifestations, but to suffer the condemnation 

 of such animals as victims of plagues, with which they do not 

 suffer, is an injustice to the farmer, a wrong to the stock-raiser, 

 the propagation of a groundless fear to the mother, an imposition 

 upon the public, an unfortunate blight upon our herds and an 

 opportunity for foreign nations, who are jealous of our progress 

 and our commercial activity, to discriminate unjustly against 

 American cattle, American dairy interests, our cows, our meats, 

 and the various food products prepared from our meats. 



There is a disease tuberculosis. It frequently exists in cows. 

 Sometimes it is local, and often it is generalized in form and is a 

 maladj7 that should be carefully watched to prevent its ravages 

 extending beyond the limits of an animal plague and exerting its 

 deteriorating influence upon the health of the human family. It 

 is an unfortunate fact that nearly all the measures employed to 

 eradicate tuberculosis, neither aim to exterminate it when it ex- 

 ists nor prevent its appearance when it does not exist. It is 

 not surprising that with an ill so deceiving, with a malady so
