LESION'S OF THE PAROTID DUCT. 
foolish and blameable proceeding, which 1 merely practised in 
order to make M. Detroye understand that such lesions were by 
no means serious, induced a slight irritation of the excretory con- 
duit of the gland. There was dulness and want of appetite. 
Three quarts of blood were taken from the jugular; the white 
regimen strictly adhered to, the hair cut from the part, and an 
embrocation applied. This was continued for four consecutive 
days, after which this treatment was replaced by vesicatory appli- 
cations over the parotid gland and its duct. All the symptoms, 
and especially the discharge, soon began daily to diminish. On 
the thirty-seventh day the horse was able to return to work. 
A long while after this accident the same horse died of disease of 
the chest. The parotid had retained its perfect integrity, and the 
canal was thoroughly cicatrized. When speaking of the morbid 
lesions we shall give an account of this curious autopsy. 
6th . — On the 20th Dec. 1843, I took off a species of scirrhous 
tumour which entirely filled the inter-maxillary cavity, and had 
resisted the application of the most energetic dissolvent means. 
The horse being thrown and properly fixed, I made a longitudinal 
incision in the median plain of the throat, and detached the skin on 
both sides. This being done, I grasped the morbid production 
with a pair of clams, confided to the care of an intelligent assistant : 
I dissected off* the left side thoroughly and without difficulty; but 
the right I found very difficult, on account of the adherence it had 
contracted, not only with the bone, but also with the masseter. 
Nevertheless, I had nearly finished the operation, when, through a 
struggle of the horse, I perceived that 1 had cut across the parotid 
duct, together with the artery and the vein accompanying it*. 
This accident was the more difficult to avoid, as neither of these 
parts had retained their natural position or course. I tied the vein 
and the artery, after having placed pledgets of lint upon the flaps 
of skin ; and I applied as a dressing, pledgets steeped in alcohol 
diluted with water. As there was an abundant discharge of saliva, 
I applied a vesicatory on the fifth day to the parotid gland and 
along the course of the duct; the wound being constantly dressed 
with tincture of aloes. 
On the twentieth day it looked well, but the saliva continued to 
flow, especially while the animal was eating. I ordered two more 
vesicatory applications. On the twenty-eighth the saliva had ceased 
to flow, and the wound rapidly approached to cicatrization. 
In the following March the horse died of glanders. Before his 
death I had occasion to see him, but was never able to perceive 
* About one-third of an inch remained attached to the tumour.
