permitting ?. Horfe to drink cold Water, while extremely 

 hot i expoling a Horfe that is tender and well kept to the 

 Night Air : And fomctimes many of -the fame Symptoms 

 will happen when the Air is too much rarefy'd and thin ; 

 for by that Means its PrelTure is not fufRcient to force the 

 Blood through the fmall V^ellels of tiie Lungs, but will oc- 

 cafion a Stagnation there, and caufe a Difliculty of Breath- 

 ing, which will be accompanied with a Cough ; and this 

 Sortj if not fpcedily cured, is the mod dangerous, both 

 as to its immediate and future Efleds. 

 tj-j ^. The Signs are, Dulnefs, Want of Appe- 



'* ' tite, a Cough, and running at theNofe; and 



fometimes it afFecls the Eyes, as we have already obferved ; 

 and in moft young Horfes, caufes Swellings about the 

 Kernels of the Throat. 



The Cough proceeds from a Diftention of the Lungs 

 which llreightens the Paflages of Rcfpiration, or it proceeds 

 from a Defluxion of Rheum, from the Kernels of the 

 Windpipe being then relaxed and diftended ; and when the 

 Difcharges from thence happen to be pretty confiderable, 

 it is by Farriers faid to be a wet Cough ; but when a Horfe 

 CO jghs without any great Matter of Difcharge, it is then 

 call'd a dry Coucji, and is look'd upon as an ill PrognoHick. 

 But a dry Cough is not always a bad Prognoilick, as 

 they imagine ; for in the Beginning of a Cold, it often hap- 

 pens only from the Oppreffion of the Lungs, when the 

 fmall Vellels, towards their Extremities, are over-charg'd, 

 jnfomuch that the Air which the Horfe draws in, is not able 

 to penetrate through their whole Subftance, fo as to 

 enter into all the little Bladders, but is fuddenly repuls'd 

 hack again, and occafions him often to cough, while it 

 meets with a Portion of the lame Air, before the Action 

 of Refpiration is begun ; and we may oftentimes obferve 

 the fame Symptoms in Horfes that are narrow chefted, 

 upon a very flight Cold ; becaufe in that Cafe, when the 

 Blood-vellels nre full, they have not Room for a fufficient 

 Elevation. But if a dry, husky Cough continue after the 

 common Symptoms of a Cold are paft, it is then to be 

 very much fufpeded as a Thing that will be of ill Con- 

 lequence, as being the Fore-runner of a Confumption. But 

 we (hall fliew the Reafon of this in its proper Place ; and 

 in the mean time proceed to the Cure of a Cold, while 

 it is unattended with any other Accidents than what are 

 commori.
