SOME ACCOUNT OF A SWINE PESTILENCE. 681 
of a distillery at Aurora, to try a series of experimental re- 
searches. To this they readily consented ; and as they were 
constantly receiving fresh hogs, there was a fine opportunity 
to make any experiments that were deemed advisable. The 
hogs on which the experiments were made, were known to be 
healthy. 
1. Six hogs that had been exposed to the malady, by being 
in contact with diseased hogs, were put into a yard by them- 
selves and fed on slop and corn ; on the fourteenth day from 
the time they were exposed to the disease they were all 
unwell ; three died within a week afterwards ; the rest re- 
covered. 
2. Ninety hogs were exposed to the disease, they were put 
into a yard by themselves, and fed on corn and water, no slop 
being given ; in thirteen days disease made its appearance 
among them, and they continued to die until sixty out of the 
ninety died. 
3. Fifty hogs were put into a pen by themselves and fed 
on slop. They had not been exposed to the disease. For 
six weeks they continued healthy. 
4. One hundred hogs that had not been exposed to the 
disease were put into a yard by themselves, and fed on corn 
and water; for thirty days no symptoms of disease appeared 
among them. They w r ere then put into a pen with diseased 
hogs ; on the thirteenth day they began to show symptoms of 
the malady, and the disease rapidly spread among them until 
forty died. 
5. Thirty-three hogs out of a lot of two hundred and sixty- 
three, were put into a pen by themselves; for six weeks they 
continued healthy. The remaining tw T o hundred and thirty 
were put into a pen adjoining which were diseased hogs. In 
thirteen days the disease made its appearance among them, 
and continued until one half died. 
6. Four young and healthy hogs were put into a pen, in 
which, four days previous, diseased hogs had been ; they were 
fed on corn and water. On the fourteenth day they were all 
unwell, one died on the fifteenth day, and in five days more 
they were all dead. This experiment shows that infection may 
be retained in a pen for several days. 
7. On the 28th of October, Dr. Sutton inoculated five 
healthy hogs, from the blood taken from the inflamed tissues 
of hogs that had died of this disease. On the fourteenth day 
(November 11th), they were all unwell, and died with but one 
exception. In three, inflammation spread from the point 
where they were inoculated, along the skin and dow n the legs, 
which became very much swollen. Dr. Sutton does not insist
