ing it becomes large and pendulous, as may be ob- 

 served in many instances amongst horses employed 

 in carts or by farmers. 



An experienced writer says, 'that horses are dif- 

 ferently affected in this disorder. The respiration 

 is quickened in some without much heaving, and 

 the abdomen in such is contracted and hard, instead 

 of being large and pendulous. It is sometimes at- 

 tended with a cough, which is not deep, but short 

 and hard, as though the lungs resisted perfectly the- 

 impulse of this exertion. On exercise, the cough is 

 much increased, after which he seems relieved : his 

 head in coughing is held low, and his neck stretched 

 out, as though he endeavoured to bring something; 

 from his throat. The face has a rigid emaciated 

 appearance ; resembling, though less violent, that 

 contraction which attends the lock-jaw. The eyes 

 are often yellow, from diffused bile ; the nostrils di- 

 lated and rigid. The appetite is not aifected by it : 

 if any thing, it is increased.' 



When the stomach is loaded, especially with 

 w^ater, all the symptoms of this disorder are more 

 easily remarked, especially on exercise. This is a 

 sure mode of ascertaining its existence. On the 

 other hand, when a broken-winded horse has had 

 two or three hours' exercise, and the stomach and 

 intestines are emptied, no perceptible indication of 

 this disorder can be perceived. 



Mr. Lawrence observes, that ' the disease of bro- 

 ken-wind seldom comes on suddenly, but is gene- 

 rally preceded by habitual coughs and eolds ; and 

 these causes are considerably aggravated by over- 

 feeding and want of sufficient exercise. In regard 

 to coughs, there is this perceptible difference betvv een 

 those which are recent and inflammatory, and those 

 which are chronic or of long standing. In the first 

 there is generally soiTxe discharge from the lungs, 

 but in the latter there is seldom any discharge 

 Y'hatever.
