150 SPECIAL CATTLE THERAPY 



Neoformations in the testicular substance of males 

 are always to be looked upon as tuberculous until a 

 negative test proves the contrary. 



This concludes the consideration of the varieties of 

 tuberculous lesions which are commonly encountered, 

 unexpectedly and yet frequently. Even from a brief 

 outline, such as this one, it can be seen how constant 

 must be the practitioner's vigil, and in what strange 

 clinical disguises localized tuberculous processes will 

 make their appearance. 



The control of tuberculosis in dairy herds depends 

 to a very great extent upon this vigilance on the 

 part of the attending veterinarian, which in itself is 

 one of the best arguments against the licensure of 

 empirical practitioners. The treatment of unrecog- 

 nized local or regional manifestations of tuberculosis 

 is one of the important factors bearing on the spread 

 of this disease.
