ON THE RE-ABSORPTION OF PUS.

ia which these depots of pus are formed after its absorption. 
These hepatic collections are rare in the horse; indeed, I have 
not yet observed them in him: but they are more frequent in 
the dog, in whom the biliary apparatus discharges a more im¬ 
portant function.

CASE V. 
A bull-dog, four years old, with suppurating wound in the 
scrotum. 
Inquiries. —About two years ago he received a violent blow on 
the genitals, which produced considerable swelling of the tes¬ 
ticles and their envelopes. This engorgement, which for a con¬ 
siderable time had all the characters of an abscess, did not 
spontaneously break, and was never opened. After fluctuating 
at several points, it ended by becoming indurated, and the en¬ 
largement remained stationary. About a month afterwards, the 
owmer perceived that the scrotum was the seat of superficial 
suppuration, and remarking that his dog was becoming weaker, 
he made him bathe in the rivef; but this produced no good effect. 
The animal soon lost his appetite, refused his food, and remained 
constantly lying down. He was then brought to the infirmary. 
He was castrated the sam.e day, by means of ligature round the 
cords, and the excision of the diseased parts below the ligature. 
A slight hemorrhage followed, which continued about an hour 
and a half, and was at length stopped by injections of Goulard- 
water. There was great prostration of strength after the opera¬ 
tion, and the animal refused all food and drink. 
Until the 16th, the wound exhaled a fetid odour, and did not 
suppurate. Lotions of chloride of lime were applied. On this 
day and the following he ate a little baked meat. 
2Sth. —The wound was of a pale red, with slight granulations. 
Two grains of emetic tartar were given, and three injections ad¬ 
ministered in the course of the day. In about an hour after the 
emetic he vomited some mucous fluid, and also some fmcal 
matter, very fetid, and of a deep brown colour. He refused to 
eat and drink, and the debility was extreme. 
31.s^.—He had continued in nearly the same state, and died 
to-day. 
Examination half an hour after death. —The peritoneum was 
highly injected, and thickly set with a great number of ecchy- 
moses. The liver, which was much larger than in its natural 
state, was filled with little tuberculous foyers: they were not 
encysted, but merely eontained a yellowish-black matter, firm at 
its circumference, and which, on pressure, suffers a purulent 
white fluid, without smell, to escape. These purulent masses
