REPORT OF CHAIRMAN OF COMMITTEE ON SANITARY SCIENCE AND POLICE. 
I2T 
the mammary gland, floating tubercle bacilli, or in the gland 
some localized tubercular masses, and apparently ignorant of 
the fact that these same channels, which might bring the 
original bacilli to this point, were sending, distributing, revolv¬ 
ing and attempting to eliminate through every excretory chan¬ 
nel the poisonous products that followed the introduction of 
these germs into the system. 
In this connection, also, I would impress upon the members 
of the association the value of mallein as an agent in the 
diagnosis of glanders, especially because there is no one disease 
which comes to us so clouded in obscurity as glanders, and 
which by physical signs more than severely tests the ability of 
an expert to decide. The use of mallein seems, as far as 
known, a perfectly safe test, but a much surer one than the 
common practice of testing by the inoculation of some other 
animal with the discharge of a questionable ulcer, or perhaps a. 
single farcy-like bud.
