26 CONTRIBUTIONS TO COMPARATIVE PATHOLOGY. 
him to-day without a struggle somewhat dangerous to both 
parties. Let him alone for a while. 
14 th . — Still stronger ; but he has become a walking skeleton. 
Coax him with every kind of food. 
21 st . — His appetite and strength increase, and the lameness 
diminishes. He followed me half way across the pheasantry for 
some pieces of biscuit, but he will not be caught. If it were 
possible, I should say that he continues to get thinner. His 
horns have not grown a bit. 
2 6th . — All at once, and without any previous symptom, he is 
as lame as ever, but now in the left knee. It is enlarged, tender, 
and hot ; the swelling extends upwards to the elbow ; there is 
no thickening about the shank bone, but the pasterns are sadly 
swelled, and the toes stand quite apart from each other, and the 
animal cannot rest the least portion of his weight on that leg. 
He must now be caught. Foment well, and give eight ounces 
of Epsom salts, with half an ounce each of gentian and ginger. 
28 th . — The swelling has a little subsided, and the patient tries 
to rest somewhat of his weight on that limb : he also feeds a 
little. Foment, and give four ounces of salts with the gentian 
and ginger daily. 
30M. — The knee and fetlock are better, but the foot is de- 
cidedly worse. There is an evident oozing between the hair and 
hoof, threatening the loss of the hoof. Continue treatment. 
July 2 d . — Unexpected by any of us, he died last night. The 
whole of the peritoneum was somewhat thickened, and numerous 
large hydatids were attached to it, some like membranous 
prolongations, and others floating loose in its folds ; but otherwise 
there was no abdominal disease. The left lung was sound. The 
right lung exhibited considerable inflammation of its substance, 
and congestion, but not enough to cause death so suddenly. In 
cutting into the capsular ligament of the knee, more than two 
ounces of purulent matter rushed out. The synovial membranes 
were thickened, and three spots of abrasion were found on the 
upper cartilage of the lower layer of bones. The animal was 
not examined farther, in order that he might not be injured for 
the museum. He died of general irritation and exhaustion, 
produced by the long-continued and dreadful pain consequent 
on inflammation of the synovial membranes of the joints. It 
seemed to be primarily inflammation of the synovial membrane ; 
and in the two first attacks confined to that membrane ; and the 
perfect use of the fetlock and the hock were regained. In the 
last attack the cartilages were beginning to be involved, and 
spots of ulceration were found on them. 
When the reader is informed, that from May the 30th to July
