ULCERATED TUMOURS, &C. 
I dissected it carefully back, and then endeavoured to isolate 
the tumour from its numerous adhesions, partly with my fingers 
•and partly with the bistoury. I succeeded thus in raising it in 
one mass, which weighed a pound and 13 oz. I feared to open 
the parotid duct; I was also close upon the internal maxillary 
artery: I tied both the one and the other, I was however 
compelled to open the parotid duct, and the result shewed that 
my fear about this was not without cause. 
There remained two gangliform tumours, the larger of which, 
of the size of a pigeon’s egg, was situated at the bifurcation of the 
jugular, and sufficiently deep to make me fear lest I should 
wound the carotid artery in removing it: the other rested on the 
side of the larynx. I hesitated to use my bistoury, but M. Leon 
determined me by the boldness of his advice; and, in fact, I 
extirpated these'tumours and some other smaller ones that were 
in their neighbourhood without any dangerous hemorrhage. 
The tumour of the eye, which was now as large as an egg, 
was very difficult to remove. It adhered to the caroncle, to the 
lower lid, to the sclerotic coat, and it buried itself under the eye 
to the very bottom of the orbit. Of my triple operation this 
was the most difficult part, and the patient suffered much. At 
length I terminated all of them without accident; I injured no 
essential part, and even the caroncle was preserved. 
My first dressing for the channel between the jaws and the 
throat consisted of a pledget of tow and cold water, kept on at 
first by two or three sutures, and afterwards by a long bandage 
which surrounded the head and neck in the form of an S, as 
recommended by Lafosse for the operation of cataract. A sim¬ 
ple soft compress covered the eye. 
The animal appeared to suffer very much, and ate nothing for 
five or six days, when she began to improve, and at the end of 
the fifteenth day the wounds in the neck and eye were cica¬ 
trized. Those under the ear had done very well at first, but they 
afterwards became fistulous on account of the opening of the 
canal of Stenon (the parotid duct), from which flowed so great a 
quantity of saliva, particulaily when the horse was feeding, that 
the litter was wet to the very bottom. I employed every means 
1 could devise or my talented friends could suggest in order to 
remedy this evil. 1 passed a ligature round the duct; I cau¬ 
terized its extremity; I employed a thin plate of lead to compress 
it accurately ; I actively blistered the parts which covered it, and 
1 passed into it an iron probe brought to a red heat. I continued 
this for two months, without any other result than occasionally 
arresting the discharge for five or six days. Seeing no other 
resource, 1 determined to extirpate the parotid gland, and it
