TWO CASES OP PURPURA. 
No. 1 was an aged 'bus horse, that had been rather out 
of sorts a few days from cold. 
On being called to him I found extensive swellings on the 
inside of both thighs and about the lips. I diagnosed the 
disease to be purpura hemorrhagica, and treated the animal 
with stimulants, laxatives, and mineral tonics. On the fourth 
or fifth day the owner sent to say that the horse had got the 
colic : on my arrival I found him in pain, but not of so violent 
a character as horses usually suffer in intestinal disease. He 
would lay still for half an hour together, with the exception of 
now and then raising his head and looking back at his sides. 
Then he would get up and paw the litter, walk round the box 
a few times, and lie down as before. The pulse was quick 
and weak, and the breathing accelerated ; but the horse did 
not sweat much until a short time before death, which took 
place in about twelve hours after the commencement of the 
pain. On post-mortem examination being made the whole of 
the internal viscera were found healthy, except about eight 
inches of the posterior part of the duodenum which were quite 
black, and on cutting the bowel open I found the canal nearly 
obliterated by blood, effused under the mucous membrane. 
There was a small portion of injesta retained in the contracted 
part. The feces in other parts of the intestine were of a 
natural consistence. 
The second case occurred to an aged mare which was used 
for running in a light dray. About six weeks ago she met 
with a severe accident and had not worked since. On Satur- 
day, the 12th of March, she was brought to me, the attendant 
stating that she appeared dull and moved very stifflly. On 
examination I found a slight swelling, firm to the touch, just 
under the larynx, and another on the inside of the off thigh. 
I suspected I had a case of purpura to deal with, and on seeing 
the mare next morning was convinced my diagnosis was 
correct, as the enlargements had considerably increased, and 
similar ones had appeared on the near thigh and under the 
sternum. I gave 01. Terebinth, et Liq. Ammon. Acetatis night 
and morning, and a dose or two of calomel. On Tuesday, 
the 15th, I was glad to find the swellings decreasing, and that 
no fresh ones had commenced, but the following morning my 
hopes were blighted by the intelligence that the mare was in 
great pain. I went to her as soon as possible and found her 
uneasy, lying down and getting up frequently ; but the pain 
was not so severe as we sometimes find it. The under lip was 
a good deal swollen, and there was a petechial spot on the 
mucous membrane about the size of a shilling. 
I immediately concluded that the ease would terminate
