STRANGLES AND DISEASED GLANDS. 493 
Symptoms . — On examination, I found an enlargement of the 
left parotid gland to an extent sufficient to cause considerable 
impediment to. the process of respiration. His appetite, 
however, was good, and the pulse undisturbed. A blister 
was applied to the part, which so much relieved him that he 
was put to work a few days afterwards. Very shortly the 
roaring returned, when the blister was repeated. By the 
15th an abscess had formed, which w 7 as lanced, and a large 
quantity of matter having a bluish aspect escaped. This 
afforded great relief, but by the 20th, the swelling had again 
increased, although there was an abundant discharge. 
22d. — Another abscess has formed between the angles of 
the jaw, and the noise occasioned by its pressure on the 
air-passages is greatly increased ; indeed the animal can 
scarcely breathe. The relief obtained by the immediate 
opening of this abscess was so marked, that in about an 
hour afterwards the breathing had become comparatively free. 
If such had not been the case I had determined upon opening 
the trachea. After this, all w r ent on apparently well, until 
the 6th of May, wffien contrary to my instructions he was 
turned to grass. 
On the 9th he became suddenly very much worse ; he 
opened his mouth widely, roared loudly in his breathing, 
staggered, and fell in great agony, the perspiration rolling 
off him in large drops. A messenger came for me, but before 
I arrived he w T as dead. On making a post-mortem examina- 
tion, I found the parotid gland much enlarged from disease. 
Several minute abscesses had formed in it; besides which a 
scirrhous tumour, as large as end resembling an egg in its 
shape, w as situated on the upper part of the trachea, where 
from its pressure it had flattened the tube, and when cut 
into was found to contain a quantity of pus. Several other 
small tumours existed about the vicinity of the glands and 
base of the tongue. The epiglottis was thickened, and the 
larynx flattened, more particularly on its upper part, and 
no doubt from the pressure of the tumour which w^as ob- 
served at the beginning of the animal’s illness. Between 
this tumour and the first two cervical vertebrae w^as a 
quantity of matter of a brownish-red hue. The velum 
palati was so much stretched, that its texture was as thin 
as the finest silk. The trachea and bronchia contained 
some blood and frothy mucus. The lungs were con- 
gested, as was to be expected from so violent a death. 
In three places in the duodenum and jejunum, for about 
a foot in length, the mucous membrane was highly con- 
gested, and covered with matter similar in appearance to
