 him to cough. If the lungs be healthy, the 

 animal coughs with a loud,, full, and clear 

 sound ; but if his lungs be affected, he coughs 

 with a short husky noise. 



This is, in general, a fair criterion to judge 

 by, although it is not solely to be depended 

 upon in all cases. It is said that certain prac- 

 tices, such as giving the horse sweet oil, or 

 a quantity of shot, will remove the appearance 

 of the disease for a short time : this fact, how- 

 ever, is verj'^ doubtful. 



In the healthy state, and during the period 

 of inaction, the animal breathes very slowly, 

 and the motion of his nostrils, ribs, and flanks, 

 is scarcely perceptible. But when broken- 

 winded, the ribs are seen at every inspiration, 

 and the flank is tucked up and expanded alter- 

 nately. A short dry cough, of long continuance, 

 is generally considered as the forerunner of 

 broken wind. But this is not always the case, 

 for a horse may cough, occasionally, for a 

 number of years, and yet not become broken- 

 winded. 



In old obstinate coughs, the animal is some- 

 times relieved by a temporary discharg'e of 

 mucus from the lungs ; and the difficulty of 

 breathing, which always, more or less, attends 

 an accumulation of mucus on that organ, ^\•ill
