IRREGULAR STRANGLES.-PURPURA HEMORRHAGICA. 707 
left side. On exploring the rectum, up which I could scarcely 
get my hand, I found an enlargement lying along the side of 
the rectum. Ordered hot fomentations to be continually 
applied by means of large woollen cloths over the loins and 
sacrum. I expect I shall have to pass a trocar through the 
side of the rectum, so as to allow the matter to flow through 
the canula, as I fear the abscess will break internally. 
19th.—On visiting my patient this morning, I was agreeably 
surprised to find the swelling pointing at the side of the anus. 
Into it I plunged my lancet, giving exit to an enormous 
quantity of pus, which flew out with great force a considerable 
distance against a wall behind. I should say there must 
have been about a gallon that escaped, and from this time 
the animal gradually recovered. 
About the same time a gray horse belonging to the same 
person had the operation of tracheotomy performed, being 
threatened with suffocation from tumefied parotid glands. It 
was performed by my son. The animal recovered without 
being a roarer, or making the least noise in his breathing 
afterwards. 
Purpura Hremorrhagica. 
The first case I will give you from memory. It occurred 
a few years ago, the subject being a bay mare, the property 
of the Rev. A. S. Irwin. She had an attack of influenza, 
from which she had so far recovered that Mr. Irwin drove 
her into town, about two miles, to get her shod at my place. 
The next day she was sent in to me again, having five or six 
large swellings between her fore legs and on the sides of the 
sternum. Being from home when she came in, the mare was 
put into a stable to await my return in the evening, during 
which time all her four legs had become so much swollen 
that she could with the greatest difficulty walk out of the 
stable. I administered a mild purgative, and sent her home, 
with directions to foment the swellings with hot water and 
woollen cloths. The following day the swelling had extended 
to the abdomen, and to such an extent I have seldom seen; 
a profuse discharge also issued from both nostrils. I scarified 
the swellings, and gave tonics combined with diuretics. A 
few days afterwards a large swelling (flattened) nearly covered 
her ribs, and on the following day or two it would seem to 
leave the body and appear along the sides of the neck, 
leaving this part again in like manner, and going to the ribs 
as before. The swelling of the abdomen continued to increase 
until it looked almost like a second belly suspended to her;
