been exposed to a cold air ajl day, or perhaps for" 

 weeks, and then removed to an hot stable . and fre- 

 quently covered with warm clothing, that the cir- 

 culation will be increased to a great degree, 

 whereby the glands of the nostrils become in- 

 flamed and obstructed, and only a thin humour, 

 resembling water, is secreted, containing a quan- 

 titv of neutral salts ; which, as the parts are left 

 undefended, act as a continual stimulus, causing 



great irritation. 



In its incipient, or first stage, we observe that 

 the nostrils look red and inflamed, and a thin hu- 

 mour is discharged. This is attended by a slight 

 cough, and some degree of fever ; the pulse is 

 hard and frequent ; a dulnefs of the eyes, some- 

 times with a defluxion of serum ; a sorenefs of 

 the throat ; and food is often returned out of the 

 mouth, owing to the irritation it causes. 



As the disease and inflammation increases, the 

 horse becomes very dull, and a listlelsnefs to action 

 takes place ; the cough becomes more frequent ; 

 the glands under the jaw become inflamed and en- 

 larged, and the fever increases, attended with 

 costivenefs. If the cough is violent, and long 

 continued, it often lays the foundation of broken 

 wind.
