FISTULA OF STENON’S DUCT. 
I am not speaking too strongly when I say, that the hypodermic 
injection of cocaine will soon be accepted by advanced veterin¬ 
arians as an integral part of the operation. 
FISTULA OF STENON’S DUCT. 
By the Same. 
About the beginning of the year my advice was asked con¬ 
cerning a running sore on a mare’s jaw, which had existed for eight 
months. Examination proved it to be a fistulous parotid duct, 
due to implication in the abscess of strangles. The portion be¬ 
tween the fistulous opening and the mouth was completely oblit¬ 
erated. When fed on hay the saliva was poured out in great 
quantities, in spite of which the mare, a handsome bay, valued at 
$350, was in good condition. 
I thought first of trying to establish an artificial duct, but 
reflecting on some previous rather disappointing trials by this 
method, I resolved to adopt a different course. A friend, an 
M.R.O.V.S., and a graduate of Alfort besides, suggested excision. 
I told him I would try Williams’ method of obliteration, but he 
shook his head and predicted abscesses, sloughing of large por¬ 
tions of skin, etc. 
The owner did not want the mare laid up long, nor did he 
want her scarred if possible. I am as good an operator as the 
average, but I confess I did not like the excising treatment; the 
arterial and venous relations of the gland seemed to entitle it to 
a certain amount of respect. I had a No. 3 Davidson hard rub¬ 
ber uterine syringe containing half-an-ounce, with a very long 
nozzle. Enlarged the fistulous opening a little and passed a soft 
uterine probe up the duct, and got the angle; next dipped the 
nozzle of the syringe in hot water and moulded to the probe; 
placed a twitch on the mare, filled syringe with Williams’ injec¬ 
tion, oiled the nozzle and passed several inches up into the duct, 
though it was a rather tight fit. A good assistant compressed 
the parts around and below the nozzle, so that there would be no 
back flow, and kept the duct compressed on withdrawing nozzle;
