CHAP. I.] HOW BROUGHT ON, TO ROARING. 237 



Vide proof at page 115. One cause of broken 

 wind, or rather that mainly predisposes the animal 

 to contract this disorder, is voracious feeding, 

 which distends the stomach inordinately, and for 

 a while gives to the animal a short-lived vigour and 

 healthy appearance. This induces its proprietor 

 to put him upon his mettle, to try the extent of his 

 powers at progression ; and as he will best perform 

 those feats upon a plentiful feed, the action of the 

 midriff and lungs thereby becomes laboured, and 

 the proper expansion of the lungs is impeded. 

 Heat and tension are the immediate consequence, 

 and broken wind of one or the other species is the 

 remote consequence. Horses that eat their litter, 

 and other hard substances, are similarly predisposed 

 to broken wind; namely, by the great distension of 

 the stomach, and inability of inspiring a sufficient 

 quantity of air to fill the lungs, whence the inert 

 cells, or portion not distended, fill tip, contract, and 

 become useless, or, upon sudden action and over- 

 distension, they burst at once. 



Cure there is none for broken wind, and there- 

 fore all that can be done by way of alleviating its 

 symptoms must be effected by management, or, as 

 it is more generally termed, by 



Regimen. Of course, the groom Would avoid 

 exposing the animal to fresh cold, and not push 

 him too hard on a full stomach ; nor indeed, give 

 away a chance of increasing the malady by the 

 same means as we have just said originally brought 

 it on. He will, on the contrary, follow an oppo-
