ON THE RE-ABSORPTION OF PUS. 
the animal had received on the cheek on January 31st. The dog 
had had the distemper about eighteen months before, and since 
that period had enjoyed perfect health. 
‘His state on his arrival at the school, —He was lively and fed 
well, but he was restrained in moving his head, and particularly 
his jaw, by the tumour beneatli. This tumour was very tender 
when *touched — somewhat circumscribed — cedematous at its 
edges, and slightly fluctuating at the angle of the right maxillary 
branch. A viscid saliva ran from the mouth, and somewhat 
embarrassed the respiration. The populeum ointment was applied 
to the tumour; emollient fumigations, and half-diet. 
Zd .—The fluctuation was more evident. On opening the 
tumour there ran from it nearly or quite a pint of pus, a little 
bloody, and very fetid. The internal surface of the abscess was 
glistening, and of a livid red colour. Inject a solution of chloride 
of soda into the abscess, apply the cautery to the edges of the 
wound, and the populeum ointment over the surface of the tu¬ 
mour; the same diet. At night the animal was dull, its respi¬ 
ration was more difficult; but, nevertheless, it searched for 
something to eat. 
4:th. —The tumefaction is considerably diminished, but the 
wound is pale, and suppurates very little. The patient is dull— 
without appetite—the respiration accelerated and irregular, and, 
from time to time, accompanied by moaning. There is a slight 
nasal discharge; the spume is viscid and abundant; and the 
beatings of the heart are strong and quick; but the pulse is 
feeble. Injections of chloride of soda into the wound; dress it 
with digestive ointment; emollient fumigations; milk with 
honey and gum as food. 
5^A.—The wound is livid ; it is scarcely moistened by a little 
serous discharge. The general symptoms are more intense ; the 
beatings of the heart are strong and quick ; the pulse scarcely 
sensible; the respiration more embarrassed; and the discharge 
from the nose very great. The animal that had been in high con¬ 
dition is reduced to a frightful state of marasmus. He died in 
the night. 
Examination at six in the morning, —The dissection of the 
tumour, and of the cyst which it formed, presented nothing that 
we had not seen in the living animal: it only enabled us to state 
with more certainty that the abscess had no communication with 
any other part. 
Respiratory apparatus. —The two pleural cavities contained 
a great quantity of sero-purulent matter^ exhaling an odour, 
which, although weaker, reminded us of the smell which had 
proceeded from the abscess under the jaw. There were no false
