communicated from animal to animal, either directly by immedi¬ 
ate contact with a diseased animal, or indirectly through contact 
with an infected or contagium-bearing medium. Formerly it

was brought about by means quite different from those operating 
in the case of contagious disease; that the propagation of infec¬

or small-pox. But since the discovery and attempted classifica¬ 
tion of specific disease germs, surely all that has passed away. 
That Dr. Peters himself does not believe in infectious diseases 
not propagated through a contagium, his experiments with the 
guinea pigs and his conclusions drawn therefrom plainly show. 
Is it not a pity then, that he should make such a use of terms as 
will be apt to produce an erroneous conception in the minds of 
some of his readers? Yours truly,
