AND BROKEN WIND. 363 



" before ; from which quantity of contained 

 ** air, the lobes of the lungs are always enlarg- 

 *• ed, as may be feen by examining the dead 

 " carcafes of broken-winded horfes." But I 

 think I can bed explain the matter in the 

 words of Dr. Darwin ; fpeaking of humoural 

 afthma, he attributes it to " a congeilion of 

 " lymph, in thre air-cells of the lungs, from de- 

 " fe61ive abforption." 



In my ideas, a redundance of lymph being 

 throw^n upon the lungs, the quantity becomes 

 too great for the capacity of the abforbent 

 veffels, hence it ftagnates and chokes up the 

 air conduits, and the theatre of its aftion being 

 more confined, of courfe refpiration mufl be 

 more difficult and laborious. The difeafe will 

 thus be always in proportion to the obftru6tion 

 in the air-cells. 



The moft general caufe of broken wind 

 lies in alternate expofure to inordinate heat 

 and cold. Nothing will enfure the difeafe fo 

 comipletely to the fatisfaftion of any experi- 

 menter, as that philofophic pra6lice already 

 celebrated, of wafhing with cold water, horfes 

 under the ardent fever of laborious exertion. 

 Moft horfes in public fervice, and many from 

 improper ftable management, have their wind 

 affetled in fome degree, the malady increafing 

 with their years. Profeflbr Coleman, I am 

 informed, fuppofes broken wind to proceed
