produced de novo. It always comes by reason of the entrance 

 of this organism into the human body, and it is distinctively 

 and emphatically an inftdious disease." 



Treatment. 



* " Treatment is unsatisfactory as being rarely successful, 

 and even then in preserving an animal which is dangerous 

 as a breeder for producing a progeny predisposed to this 

 disease, and for slaughter and dairy purposes as possibly 

 conveying the malady to man." 



Prevention. 



* " This would include drainage, shelter of pastures by 

 trees, avoidance of changes to cold or damp localities, a 

 warm, sunny location for farm buildings, suitable feeding 

 and watering, the prevention and cure of all debilitating, and 

 especially chronic diseases, protection against overwork, or 

 excessive secretion of milk on a stimulating but insufficiently 

 nutritious diet, securing young, undeveloped animals against 

 breeding and milking at the same time, rejection of tubercu- 

 lous subjects from breeding, the prompt removal of all such 

 animals from pastures or buildings used for the healthy, and 

 the thorough disinfection of all places where they have been 

 kept." 



■f- " A consideration of the causes furnishes the key-note 

 to that of prevention, and all that can be said in the matter 

 can be summarized in a few sentences: 1. All flesh and 

 offal of affected animals, especially in the advanced stages of 

 the disease, should be destroj'ed by fire or otherwise. 2. 

 All suspected animals should I)e carefully isolated until 

 pathognomonic signs have been developed. 3. All actually 

 affected animals should be slaughtered. 4. All contaminated 

 food, litter, etc , should be disinfected or burnt. 5. All 

 infected houses should be disinfected. 6. No animal whose 

 history is tainted, even in the slightest degree, or in whose 

 system there exists the least suspicion of tubercle, should be 

 used for breeding purposes. 7. Great care should be exer- 

 cised at the period of birth to avoid any influences which will
