permitting a Horfe to drink cold Water, while extremely 

 hot 5 expoling a Horfe that is tender and well kept to the 

 Night Air : And fometirnes many of the fame Symptoms ■ 

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

 for by that Means its Prellure is not fufficient to force the 

 Blood through the fmall Veflels of the Lungs, but will oc- 

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

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

 Sort, if not fpeedily cured, is the moil dangerous, both 

 as to its immediate and future Effeds. 

 tj-, o- The Signs are, D.ulnefs, Want of Appe- 



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



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

 and in moll young Horfes, caufes Swellings about the 

 Kernels of the Throat. 



The Cough proceeds from a Diftention of the Lungs 



which llreightens the Pafiages of Refpiration, or it proceeds. 



from a Defluxion of Rheum, from the Kernels of the 



Windpipe being then relaxed and diilended ; 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 Cough, and is look'd upon as an ill Prognollick. 



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



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



pens only from the Opprellioh of the Lungs, when the 



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



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



to penetrate through their whole Subllance, fo as to 



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



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



meets with a Portion of the fame Air, before the Adion 



of Refpii-ation is begun ; and we may oftentimes obferve 



the fame Symptoms in Horfes that are narrow cheiled, 



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



Blood- veilels are full, they have not Room for a fufficient 



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



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



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



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



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



in the mean time proceed to the Cure of a Cold, wl'iile 



it is unattended with any other Accidents than what are 



common.
