AND ITS RELATION TO ANIMAL LIFE 97 



manuring of the pasture is the only certain 

 cure. 



Therefore indirectly, if not directly, the milk 

 of ^a tuberculous cow tends to set up the con- 

 ditions suitable for the growth of the human 

 form of the disease. 



The same argument is applicable to human 

 beings eating the flesh of an animal liable to 

 or suffering from this disease. 



And as it is recognized that milk is a product 

 of the tissues and not directly of the food, it 

 follows that the tissues of an animal liable to or 

 suffering from tuberculosis are deficient in fats 

 and nitrogenous substances. It therefore follows 

 if a human being were to live largely on the flesh 

 of animals so impoverished, that the tissues, 

 blood, etc., of the said human being would 

 become poor in fats, nitrogen, etc. 



In fact, just as a good quality of grain is 

 sixteen times superior to a poor grain in its 

 feeding qualities, so is the flesh or milk of an 

 animal immune to tuberculosis, or other 

 bacterial disease, infinitely superior in its 

 feeding properties to the flesh or milk of an 

 animal either liable to or suffering from tuber- 

 culosis or other bacterial disease.
