je(El?, and the Diameter of their VefTels ; that is, a 

 Cathartic or purging Medicine will operate in Man 

 in a fmaller Dofe, as the Subje6l is Man, fo as to 

 carry off the Excrements by Stool, than it will do 

 in a Horfe, notwithftanding the different Conftitu^ 

 tions of thefe two Animals : For the prone Pofture 

 of a Horfe guards him (as I have faid before) from 

 Difcharges by Stool as much as may be ; and there- 

 fore Cathartics may be given in pretty high Dofes, 

 which will only ( according to the Idiofyncrafy or 

 peculiar Temperament of Horfes Bodies) operate as 

 an Alterative. So that I advife never to tofs in one 

 Purge upon another, when the firll does not work, 

 but let the Horfe alone a Week, and heighten the 

 Dofe then, provided Purging be thought abfolutely 

 neceflary : But, no doubt, it is in Horfes as in Hu- 

 man Bodies, with Relation to this Particular j for §0,^,5 

 really there are fome, both Men and Horfes, that Horfe?, as 

 it is hazardous to give them fuch a Dofe as will well as 

 purge them to a common Degree : Therefore, when t^^^\ ^'^^^ 

 this fo falls out, it is beft to carry oft the Caufe ofp^j.a^ 

 the Diforder through fome more proper Out-let, 

 which Nature is not fo much bent againil, as ihe is 

 to this particular Difcharge by Stool.
