288 Report on the Health of Animals of the Farm. 
grey scabs, and the general mass of cuticle was being rapidly 
removed from the body. The countenance was haggard, and 
the gait feeble and unsteady. The extremities were cold ; and 
the bowels constipated. The belly was tumid, and resonant on 
percussion. Pressure revealed some abdominal tenderness, but 
whether this arose from the tympanitic state of the belly, or 
from actual intestinal disease, could not be well determined. 
7th. — All the symptoms observed yesterday are intensified ; 
the abdomen is now distended to an enormous degree. The 
animal has a dull, confused, and stupid look ; and convulsive 
tvvitchings of the muscles are present to a greater or less extent 
over the entire body. 
Sth. — The bowels are still constipated, and the tympany is 
undiminished ; the nervous depression is aggravated. The 
animal obstinately refuses to move, even though pressed to do 
so. A peculiar groan is emitted when any attempt is made to 
disturb him. 
Qth. — This morning the animal is in a state of collapse. He 
died about noon. 
£xpcriment IV. — This may be called a purely accidental ex- 
periment ; nevertheless, it serves to illustrate the incubative 
period of the affection, and to determine its virulently contagious 
nature. The case also furnishes data as to the progress of the 
symptoms, and serves with the others to indicate the order of 
events as they occur during the fever process. 
The animal which had been procured by Mr. Priestman for 
the purpose of being inoculated escaped from its house, and 
gained access to the pig used in Experiment III., on July 1st — 
twenty-one days after its inoculation. It was allowed to remain 
with the experimental pig until the 6th of July, when both of 
them were brought to the College. At this time infection was 
clearly established ; and although the animal exhibited no 
marked signs of illness, a distinct eruption of raised, red spots 
existed on the breast, and on the inner side of the arms. The 
spots were not numerous, but isolated, and scattered over a large 
surface. The eyes were suffused, and slightly injected ; food 
was taken freely, but there was considerable thirst. 
July 1th. — The eruption has extended to the abdotaen and 
the inner side of the thighs. In the last-named parts, the spots 
are numerous, and grouped together in confluent masses. The 
bowels are constipated, and the fjEces coated with thick tena- 
cious mucus. Towards evening there were violent paroxysms 
of shivering, and a great desire for warmth was manifested. 
On the spots erupted in the morning vesicles are developing, 
and the surface of the skin is moistened with exudation. The 
face is pinched, and presents a painful aspect.
