LESIONS OF THE PAROTID DUCT.

CHAPTER I. 
Historical Considerations relative to Lesions of the Parotid Duct 
in the Horse. 
Fistulse of the Stenonian duct do not appear to have been noticed 
in veterinary medicine before the year 1768. Lafosse, jun., then 
writes, for the first time, that wounds in this excretive canal can- 
not be cured* * * § . 
In his “Cours d’ Hippiatrique,” this same author, without ex- 
pressing himself explicitly, seems, nevertheless, to infer that they 
are very serious, and rarely cured. He recommends that no treat- 
ment whatever should be employed, and, above all, the use of any 
sharp instrument avoided, which always aggravates the evil, and 
the wound simply kept clean, and washed with astringent lotions, 
which will eventually moderate the flow of salivat. 
Vitet, and his cotemporaries, who were but so many servile 
copyists of Solleysel and Lafosse, recognize, with this learned 
hippiatrist, the gravity and the incurability of parotidean lesions. 
They advise that the evil consequences which they are likely to 
produce, should be averted by the application of a mixure composed 
of the white of an egg, alum, and vitriol, to the opening in the 
canal, which is to be maintained in its place by means of a com- 
pressive bandagef. 
M. Huzard, jun., professes nearly the same opinion as Lafosse, 
jun., respecting the importance of the fistula of the Stenonian duct, 
but differs from him as to the manner in which they should be 
combatted. According to this talented author, there are three ways 
of obtaining a cicatrization : 
First, By tying or compressing the canal at an intermediate 
point between the gland and fistula. 
Secondly, By provoking the formation of a dry scar by means 
of actual or potential cautery. 
Thirdly, By perforating the cheek with a stylet, introduced 
through the fistula, and passing a small seton there, in order to 
prevent the artificial opening from closing up§. 
In order to find more circumstantial facts relative to the progress, 
consequences, and treatment of fistula of the excretive canal of the 
parotid, we must pass on to 1825, the period at which M. Leblanc 
published an extraordinary case of cure by complete extirpation of 
of the parotid gland. After having given a detailed description of
