 them, or from injury.

 more or loss general fever. 



What to do. — Bathe them with hot water and apply linseed poultices. 

 Give internally fever mixture. No. 18, till the fever is subdued. If the 

 gland suppurates and comes to a point in any spot, open it, and continue 

 the poultices as before. 



XrV. Fistula of the Parotid Duct. 



Causes. — Sometimes from a tumor or lump of hardened food in the 

 region of the parotid duct (in the cheek opposite the third molar of the 

 upper row of teeth), the opening of the duct becomes obstructed, 

 inflammation sets in, and the duct often breaks out in a fresh spot. And 

 on account of there being a constant flow of saliva, the opening soon 

 becomes flstulous. 



How to know it. — A sore is found on the cheek, usually on the outside, 

 but sometimes on the inside ; but the inner one does little harm as 

 the saliva is not wasted. The saliva flows continuously, but more freely 

 during mastication. 



What to do. — Clip off the hail- around the opening, and remove any 

 irritant or obstruction on the inside ; see that the natural opening is clear. 

 Scarify the edges of the external opening to make a fresh wound of it ; 

 then apply the paste. No. 19, to the opening, and let a cold linseed poul- 

 tice go on directly over it. Dress it in this manner twice a day, and the 

 fistulous opening will soon close if the natural passage is kept open.
