TUBERCULOSIS. 
By Prof. E. P. Niles, D.V.S. 
A paper read before the Virginia State Veterinary Medical Association. 
(Continued from page boo and concluded .) 
All germs that cause disease do so by the poisonous products 
of their growth and multiplication within the system. In tuber¬ 
culosis then, it is this chemical poison that causes the lesions, 
and the more rapidly this poison is formed the more marked 
will be the symptoms, and the sooner will the disease prove 
fatal. The system, as well as the milk of tuberculous animals, 
contains to a degree corresponding to the extent of the disease, 
a quantity of these toxalbumins, which when consumed with the 
flesh and the milk by tuberculous people, adds just so much 
more poison to the patients system, thus converting what may 
be, in many instances, local tuberculosis, into a general form of 
the disease, and possibly cutting short the life of the individual 
a number of years. This theory is self evident when we stop to 
consider the manner in which Koch’s lymph or tuberculin exerts 
its influence on tuberculous subjects when injected into the sys¬ 
tem. 
The symptoms of tuberculosis are too well known to call for 
any discussion in this paper.
