LESIONS OF THE PAROTID DUCT. 
349 
1. On the 1st Dec. 1838, I introduced the point of the cautery 
among the glands of the throat. On the fourth day I perceived 
that I had touched the parotid duct with the iron. Desirous of 
studying the progress of the wound, I merely caused all alimentary 
matters that required much mastication to be discontinued. 
The wound was dressed, successively, with tincture of aloes, 
pledgets of tow, and desiccatives. On the 28th of the same month 
the cicatrization was complete. 
2. On the 3d May 1839, the left duct was opened in its glossal 
portion by a hot iron. When the scar fell, I discovered what had 
happened, which I had previously suspected, on account of the adher- 
ence of the gland to the maxilla at the part over w r hich the canal 
passes. As the discharge of saliva was considerable, I covered the 
surface of the wound and the course of the canal with blistering oint- 
ment, the action of which was followed up by the application of a hot 
iron. On the 13th day, the discharge had almost ceased; on the 
17th, the wound was apparently cicatrized; on the 22d, all re- 
gimen was discontinued, and the animal returned to his ordinary 
rations. 
3. On the 15th June, 1840, I opened the right parotid duct 
while introducing the cautery into an abscess arising from strangles. 
On the 20th, the saliva began to flow; on the 24th it was dis- 
charged abundantly, notwithstanding a vesicatory was applied. 
I renewed it, and extended it over the parotidean region, up to the 
part where the duct rises. The horse was put on the before- 
mentioned regimen, and kept tied up with two straps. On the 10th 
of July he was perfectly cured. 
4. On the 10th May 1842, while incising, with a straight bis- 
toury, a farcy-bud, situated on the left side of the face, on the 
course of the duct, I opened the latter. The horse had scarcely 
returned to his stall when a discharge of saliva commenced, which 
was very considerably increased on his being given a few handfuls 
of hay. I made two successive vesicatory ^applications, kept the 
patient on white diet, and, at the end of fifteen days, he would 
have been able to return to work if other farcinous wounds had 
not kept him in the infirmary. 
5. On the 6th June 1843, I extirpated the glands of the throat 
in a regimental horse. In a sudden movement of the head my 
bistoury touched the right duct while seeking to detach it from the 
glands, with which it had contracted a close adherence. In order 
to convince my assistant, M. Detroye, that the canal actually was 
open, I introduced a knitting-needle into it to the extent of an 
inch or more ; and this introduction was increased in consequence 
of a sudden bobbing of the animal’s head on the chest. This
