On the following day, the animal walked slowly about, seeking for something to eat; he gave him some milk. On changing the dressing, he tried whether he could again introduce any sound into the wound; but it would only penetrate a very little way; indeed, re-union by adhesion had already taken place. On the fifth day, the animal was in good spirits; the wound had a healthy red appearance, and all tended to a speedy cure. On the eighth day he was sent home to his master, a distance of two leagues from his house. He saw the dog eighteen months afterwards, and he was as eager as ever after his game. The following is a case of rupture of the heart:--A black pointer, of the Scotch breed, had every appearance of good health, except that she frequently fell into a fit after having run a little way, and sometimes even after playing in the yard. She was several times bled during and after these fits. When I examined her, I could plainly perceive considerable and violent spasmodic motion of the heart, and the sounds of the beating of the heart were irregular and convulsive. She was sent to the infirmary, in order to be cured of an attack of mange; but during her stay in the hospital she had these fits several times: the attack almost always followed after she had been playing with other dogs. She appeared as if struck by lightning, and remained motionless for several minutes, her gums losing their natural appearance and assuming a bluish hue. After the lapse of a few minutes, she again arose as if nothing had been the matter. She was bled twice in eight days, and several doses of foxglove were administered to her. The fits appeared to become less frequent; but, playing one day with another dog, she fell and expired immediately. The 'post mortem' examination was made two hours after death. The cavity of the pericardium contained a red clot of blood, which enveloped the whole of the heart; it was thicker in the parts that corresponded with the valve of the heart; and on the left ventricle, and near the base of the left valve of the heart, and on the external part of that viscus, was an irregular rent two inches long. It crossed the wall of the valve of the heart, which was very thin in this place. The size of the heart was very small, considering the height and bulk of the dog. The walls of the ventricles, and particularly of the left ventricle, were very thick. The cavity of the left ventricle was very small; there was evidently a concentric hypertrophy of these ventricles; the left valve of the heart was of great size.
