What to do.— It can be opened without the slightest danger. Insert 

 the knife inside the nostril and make a free opening and evacuate the 

 pus. Inject lotion No. 6, twice a day. It is not likely to recur. 



n. Polypus. 



This is a tumor-like excrescence growing in the nostril. It may form 

 in any part of the passage from the muzzle to the throat. It is usually 



a fleshy bulb, on a pedestal or neck. It varies 

 ^ «|h in size from a cherry to a man's fist. 



\ T How to know it. — The breathing is obstruct- 



ed, to a certain extent, and, upon examination, 

 the polypus is found. 



What to do. — Cast the horse, and catcb 

 firm hold of it with the forceps for the pur 

 pose, then pass the chain of an ecraseur ovei 

 it, an 1 cut it out close to the surface from polypus 

 which it grows. A fine copper wire may be 

 used, if the ecraseur cannot be had ; pass the 

 wire over the polypus and twist it off. There will not be hemor- 

 rhage to do any harm. The polypus may grow again, but it is 

 not very likely to. 



m. Catarrh.

Under this name are included acute catarrh and the common cold 

 when it is confined to the nose. It is simple in itself, but all inflamma- 

 tions of the upper air-passages are liable to run 

 down into the lungs and cause bronchitis and 

 pneumonia, which are always serious. Catarrh is 

 inflammation of the mucous membrane of the nos- 

 trils, and often extends to the sinuses of the head, 

 especially the frontal sinuses situated between the 

 eyes. 



Causes. — Exposure to cold winds, rain and snow 

 storni;>, cold nights, etc. 



How to know it. — There is always a discharge 

 from one or both nostrils. The discharge is thin 

 watery mucous at first, and turns to muco-puru- 

 ient in the course of a couple of days ; and then 

 to purulent, if not properly treated. The muco- 

 purulent is white and frothy ; the purulent is yellow, and has an offensive
