BROKEN WIND. zzt 



examining the matter a little r?iore atienthel^^ 

 two very probable reafcns may be adduced, 

 tending to lead us to a much more RA- 

 TIONAL opinion of tlie caufe. 



For inftance, whether horfes who have been 

 in the habit oifull ov foul feeding, with a very 

 trifling portion of exercife, and without any 

 internal cleaniing fi'om evacuations, compul- 

 fively obtained by purgatives or diuretics y may 

 not conflantly engender a quantity of vifcid, 

 tough y phlegmatic matter ; which accumulating 

 by flow degrees may fo clog and fill up fome 

 of that infinity of minute pafi^iges with which 

 the lungs are knov/n to abound, as probably to 

 obilrud the air veflels in their neceflJiry ex- 

 panfion for the office of refpiraticn. And whe- 

 ther this very probable obflruction, or partial 

 fupprefijion, may not in fadden, hafly, and 

 long continued exertions, rupture others, and 

 by fuch local deficiency aiTecft the eiafttcity 

 of the whole ? The probabiUty, and indeed 

 great appearance oi this progrefs, has ever in- 

 fluenced me m.oft forcibly to believe that fuch 

 obftrudlions o?:ce formed, the evil accumulates, 

 till a multiplicity of the veiTels become im- 

 pervious, and render the lu?2gSy by their con- 



flant
