110 NAVIN ON THE HOESE. 



Oils, and it may be distinguished from other diseases by the 

 characteristics mentioned when we come to speak of the 

 causes. A discharge of yellowish mucus from the nose, of a 

 thick character, and in Large quantity, and thrown out many 

 times during the day, is the only particular symptom of the 

 disease. This discharge is subject to certain changes; some- 

 times stopping for several days, in fine weather, and then re- 

 appearing as bad as ever. It may also assume a greenish 

 hue, or be streaked with green, when the horse is at grass. 

 This is caused by the green coloring matter of the grass mix- 

 ing with the mucus far back, where the nostrils open into the 

 mouth. It will occasionally be streaked with pus, or matter, 

 which must be discharged from ulcers within the cavity of the 

 nose. The disease may continue for many years, and do the 

 horse but little apparent injury; but, by its continual wasting, 

 it may reduce the horse to low condition, and, consequently, 

 predispose to other diseases, or even destroy him. This dis- 

 ease is very annoying, as it renders every thing about the 

 horse most filthy. 



Causes. — Many contrary opinions of the nature and cause 

 of this disorder are entertained. Some are of opinion that it 

 is a forerunner of glanders, or is the first stage of it, and, if 

 neglected, will terminate in it. Others think it the effect of 

 "broken wind." Several other causes are assigned. That it 

 is not necessarily connected with glanders, I think is evident 

 from the following facts: Gleet is a profuse discharge; gland- 

 ers is a scant one. The discharge in gleet changes its color, or 

 is stained by the food; the discharge in glanders keeps of one 

 color. Glanders ulcerates the nostrils, with no tendency to 

 heal; gleet does not, or very seldom, and when ulcers do oc- 

 cur, they heal of themselves. Gleet never runs into farcy; 

 glanders often does. I have known horses to have gleet for 

 five or seven years, and run and work with others, and never 

 infect them, or "give them the disease." 



Any disease that reduces the constitution may, perhaps,
