in horses, it resembles a round ball attached to the 

 edge of the lower jaw, an elastic encysted tumour 

 or rather like an encysted tumour. When I was called in 

 to see a horse, which proved to be so effected, and telling 

 the gentlemen that so long as the ball did not break, it 

 would do the horse no injury, and that I would not re- 

 commend its removal, he said he would give five hundred 

 dollars if the horse had another on the other side, then 

 he would look like an Angora goat. 



Parotid Duct— Open and Fistulous.— This is a 

 serious affection, for every movement of the jaw in 

 chewing or masticating the feed the glands pour out the 

 saliva which should mix with the feed, and assist in the 

 act of digestion, but on the contrary is poured upon 

 the ground and is thus lost. The animal becomes 

 thin of flesh, gets weak and after a time dies a miserable 

 object. 



Causes.— Injuries, or accident to the gland, or its 

 duct resulting in suppuration and from the mobility of 

 the parts, fistula is established. 



Treatment— Fevf horse doctors or farmers can cure 

 this affection. An expert or accomplished surgeon is 

 only able to effect a cure, and this will be by closing the 

 open or fistulous duct so that the saliva will with the feed 

 find its way into the stomach. 



India rubber dissolved in chloroform, applied over the 

 mouth of the wound, when it is thoroughly dry will stop 

 it for a few days, and by continuing this application, a 

 cure in a very many cases can be made. 



Pathology.— A department of medical science, 

 which treats of the causes of disease, and of the appear- 

 ances of diseased parts when living or dead.
