INFECTIOUS SWINE DISEASES IN THE UNITED STATES. 
817 
International Veterinary Congress in which they gave a very clear 
history of the nomenclature of these diseases and in which they 
adhered to the classification of the Bureau of Animal Industry. 
They also inclnded in this paper the results of their investi¬ 
gations of numerous outbreaks of hog cholera, often complicated 
with swine plague, in the State of Maryland. The very few 
points in the pathology on which they differ from the conclu¬ 
sions of the Bureau will be referred to in later paragraphs. 
In order that this-part of the subject may be as clear as 
possible I have appended a partial list of the names assigned to 
those swine diseases which have been found to be identical 
with, or closely related to, the American hog cholera and swine 
plague. The results of the more important of the large num¬ 
ber of special investigations whicli have been made in both the 
United States and in Europe to determine these facts have been 
largely brought together in the writings of Drs. Smith and 
Welch, who themselves have done most to elucidate our knowl¬ 
edge of these affections.
