CONTAGIOUS PLEURO-PNEUMONIA IN CONGRESS. 547 
current medical knowledge they would have found no occasion 
for the slanders in question. They would have found the veteri¬ 
narian Henri Eouley sitting as the honored President of the 
Academie des Sciences, at Paris; they would have found Chau- 
veau, of Lyons, contributing more than any other single man to 
demonstiate that contagion is dependent on living organized par¬ 
ticles, which can be filtered from a virus, and will then leave the 
liquid non-infecting; they would have found Toussaint and Ger- 
lach, now gone to their reward, heroically demonstrating the 
tiansmission of tuberculosis by flesh, milk and other materials, 
and laying broad and sound foundations for the restriction of this 
“white plague of the north;” they would have found Bollinger 
demonstrating the existence of actinomycosis in animals, and 
tracing its connection with the same deadly disease in man; they 
would have found Arloing tracing the difference between the 
bacillar anthrax, deadly to man and beast, and the vibrionic an¬ 
thrax from which man is exempt; they would have found a host 
of others elucidating the different phases of the life history of the 
germs of the different infectious diseases of the lower animals and 
of man, and placing sanitary medicine on a solid basis, of which 
our two political doctors evidently have not the remotest concep¬ 
tion. They would have found, even in America, that the despised 
veterinarian has made advances of the most substantial kind in 
regard to the contagious diseases of fowl cholera, swine plague, 
and that even in the case of the lung plague itself he had devised 
a mode of giving immunity to cattle exposed to infection without 
the dangerous resort of inoculating the disease germ itself. If 
they had taken the trouble to inquire, they would have found that 
numbers of the most eminent members of the medical profession 
in Hew York and Brooklyn had personally investigated the work of 
the veterinarians in that city in 1879-80, had abundantly satisfied 
themselves as to the nature of the disease and of the effectiveness of 
the work then accomplished. Whenever a physician inclined to 
assume the position now taken by Drs. Swinburne and. Gallinger 
it was only necessary to secure his attendance at the cow-stables 
and the post-mortems in order to convert him thoroughly from 
his skepticism. Our detractors would further find, if they were
