HEPATIRRHCEA—RUPTURE OF THE LIVER. 
Feh. 19, 1836.—A horse suddenly exhibited the following 
symptoms. Increased respiration; profuse perspiration; great 
prostration of strength; pulse much accelerated and very small, 
and membranes blanched. The pulse at the jaw continued to sink 
until it was quite imperceptible; the horse then became uneasy, 
and died about twenty hours after the first appearance of disease. 
All the thoracic and abdominal viscera were perfectly sound, 
excepting the liver, which was full of extravasated blood in various 
places, and an opening three or four inches in length had taken 
place in the peritoneal coat of one of the small lobes, so that about 
three pails-full of blood had escaped into the cavity of the abdo¬ 
men, which was very black, and partly coagulated. 
March 19, 1836.—An aged gelding appeared to be restless; 
the respiration was quickened; the appetite was gone; there was 
profuse perspiration, and the animal was stupid. He suddenly 
fell while the coachman was bleeding him, and when only a small 
quantity of blood had been abstracted. When I saw him, a few 
hours afterwards, the membranes were blanched, the pulse frequent 
and thready, indicating the near approach of death. The liver, 
especially the middle lobes, were filled with extravasated blood, 
and a lesion of considerable extent in the peritoneum covering 
the abdominal surface had filled the abdomen with blood. 
ANEURISM OF THE AORTA. 
April 19, 1836.—An aged bay gelding was admitted for ex¬ 
tensive fracture of the bones of the face, which undoubtedly would 
have terminated happily had it not been for the following circum¬ 
stance :— 
On May 15th, at six P.M., he was seized with restlessness, pro¬ 
fuse perspiration, laborious breathing, and pulse, although not much 
accelerated, yet strong, full, and accompanied by a peculiar thrill, 
and which was not subdued until more than eleven quarts of blood 
had been abstracted. The membranes did not present the slightest 
injection. Sedative and aperient medicines were given, with ene- 
mata, and he seemed to be relieved. On the following morning 
he appeared quite cheerful; but in the afternoon the symptoms of 
the preceding day returned, and were met by the same treatment, 
but without afibrding the slightest relief. The horse died in the 
evening. 
The abdominal viscera were healthy. The lungs and heart were 
large, but apparently healthy. The abdominal aorta, near tlu^ 
part where the anterior mesenteric artery is given oil’, was the seat
