distinct diseases, the one known as hog cholera and the other known as swine 
plague. They are due to separate and distinct organisms, which differ morpho¬ 
logically in their behavior in culture media, and in their reaction when inoculated 
into animals. It will not be necessary to go into the details of differentiation, as 
they have been placed before the profession many times in the past few years. 
Suffice it to say that in this report, while differing in some points from the con¬ 
clusions reached by the workers on this subject in the Bureau of Animal Industry, 
the recorded observations harmonized with the facts observed in the investiga¬ 
tions of these gentlemen, as reported since the year 1885. 
Examination of direct slab cultures from the spleen, sent by Dr. F. S. Bil¬ 
lings, proved them to be, in nearly all instances, pure cultures of the hog cholera 
bacillus. Much confusion has resulted, in the opinion of these investigators, 
from Dr. Billings’ attempt to identify this organism with that uf schweineseuclie. 
PLEURO-PNEUMONIA CONTAGIOSA. 
Nothing has been done lately, that I am aware of, in the investigation of 
this disease. The methods employed by the government—that of slaughtering 
diseased and exposed cattle, and the thorough disinfection of stables—have been 
so far successful that to-day the disease is thought to exist only in a very limited 
area around New York City. 
Many more observations upon contagious and infectious diseases have been 
made, but the time will not permit your committee to report further upon them 
at this meeting. 
Pres. Michener: I will call upon Dr. Salmon for the report 
of the Prize Committee. 
Dr Salmon: Mr. President, there have been no papers pre¬ 
sented to me as chairman of that committee, and consequently no 
prizes to be awarded. 
Pres. Michener: I will call for the report of the Special Col¬ 
lege Committee, of which Dr. C. C. Lyford, of Minnesota, is 
chairman. 
REPORT OF THE SPECIAL COLLEGE COMMITTEE. 
By C. C. Lyford, M.D., Y.S., Chairman. 
Mr. President and Gentlemen: 
I sent letters to the different colleges, with a request to answer a certain list 
of questions regarding the course of instruction they would suggest and the re¬ 
quirements, with a view to establishing a uniform course of instruction. I re¬ 
ceived from many of them simply their prospectus, and from others I received 
letters which I will read : 
Montreal, 5th September, 1890. 
Dear Lyford: 
In reply to yours of August 20th, I beg to say that I have repeatedly sug¬ 
gested what is now proposed, and of course will only be too happy to find that 
others are working in the same direction. 
I have, however, given up any expectation of such a desirable arrangement 
being arrived at, in Canada, at least.
