the most so of any of the problems encountered in their inves¬ 
tigation, and it will still be necessary to have the results of 
other and repeated observations before we can fully describe 
the range of morbid anatomy possible in either affection. Per¬ 
haps of the mooted questions the most important is in regard to 
the existence of swine plague in epizootic form. 
Concerning swine plague as an independent disease the fol¬ 
lowing, and heretofore unpublished observations, are of special 
interest. In the late fall of 1895 I had occasion to spend a few 
weeks with Dr. C. N. Hewitt, of the State Board of Health, 
studying an infectious swine disease in southern Minnesota. 
During this period we made careful post-mortems, and as 
thorough a bacteriological examination as it was possible under 
the circumstances, of one or more animals in each of twenty- 
nine herds. In many of these cases the lesions were largely 
restricted to the lungs, the digestive tract being normal. On 
the other hand, the ventral, cephalic and cephalic portion of 
the principal or caudal lobe of one, and usually of both lungs, 
were hepatized. As a rule there was no pleuritis. Pure cul¬ 
tures of the swine-plague organism were obtained, and rabbits 
inoculated with pieces of the hepatized lung from a few of the 
animals, died in from 16 to 48 hours of septicaemia, due to the 
swine-plagiie bacillus. 
In a few cases the lesions varied from this form. Thus in 
one instance, a pig, of about thirty pounds weight, exhibited a 
slightly enlarged spleen, haemorrhagic kidneys, and small areas 
of slight hypersemia of the mucous membrane of the intestine. 
The tips of the ventral lobes of both lungs were collapsed. 
From the kidney, pure cultures of a very virulent swine-plague 
organism were obtained. Rabbits inoculated with a bit of the 
cortex of one of the kidneys died in 16 hours and from its organs 
pure cultures of swine-plague bacteria were secured. In a few 
herds, especially those near villages where the pigs were fed 
largely on kitchen refuse, there were a considerable variety of le¬ 
sions from which Bacillus coli couimunis and other bacteria were 
isolated, but, so far as I was able to determine, the bacillus of
