doctrines in connection with some important in- 
fectious diseases. 
Elsewhere I have given an account of very 
conclusive evidence showing that some of the 
forms of Septicemia have been experimentally 
demonstrated to arise from common micro-organ- 
isms, and yet, when thus established, they are found 
to be associated with so-called “specific” organisms, 
capable of acting as contagia for the spread of these 
diseases to other animals. What actually occurred, 
and its significance, was thus referred to :1— 
“The production of two different forms of septi- 
cemia by the inoculation of some of the same 
putrid material into different sites is a matter of 
the greatest importance. The putrid blood under 
the skin gives rise to one form of specific micro- 
organism and contagious disease; while two or 
three drops of the same putrid blood introduced 
into the peritoneal cavity of a similar animal give 
rise to swarms of a different organism and the 
development of another contagious affection. The 
differences in the inflammatory processes in the two 
situations are capable, that is, of transforming some 
common micro-organisms into two quite different 
specific Bacilli.” Here, then, we have a striking 
illustration of the views originally expressed 
by Professor Heuter and more recently by 
Hueppe. 
There is reason to believe, again, that the so-called 
typhoid Bacillus of Eberth is only a modification of 
an extremely common putrefactive organism. Thus
