IChap. V. Some General Rules^ iyc. ip 



Blood than a rforfe that is full aged i and a full aged 

 Horfe fooner than an old Horfe, becaufe all young Animals 

 are vigorous in their Appetites and Digeftion ^ but yet a full 

 aged, or an old Korfe, if either be hardy or ftrong, may 

 overcome all Lofles of this Kind, better than fome young 

 Horfes, who are of a wafhy and delicate Make, ^ut I 

 ihall now proceed to Purging* 



I need not ofter to explain what Is In i>jhat Cafes 

 meant by Purging, fince every one knows P^^^^ng is 

 that it is the difcharging of Humours and ^^'^Jb f^"/- 

 Excrements thio' the common Pallages of Ao'- 

 the Belly. The Way this Operation is performed, is with 

 fuch A lediciivcs, as by their Irritation ftimulate the Mem- 

 branes of the Gli's, whereby the Periftaltick Motion is 

 quickened fo as to (hake off their Contents. But if the 

 Dofe or Potion happens to be large, or if it be made of 

 fuch Things as abound much with thofe ftimulating Parti- 

 cles, or, to exprefs it after the common Way, if very ftrong 

 Phyfick be given, it not only carries off what is contained 

 in the Gu^s, but hkewife caufes fuch frequent and reitera^ 

 ted Tv/itcl... , as drives a rhore than ordinary Quantity of 

 Blood into i.iK.ie Parts, whence is feparated and difcharged 

 Abundance of Serui^y which is thrown off hy the com- 

 nion PailagcS above mentioned. And hence it is evident, 

 that Phylick n-ay be i'o ordered, as to carry off more or 

 lefs of the Su'Mlance of tns Blood, according as the Dofe 

 ss enlarged or diininidicd, or as it abounds more or lefs 

 with tnofe purging P.iriicl£s ; and confequently that it 

 tnay be rendci'd jia.er pro£;able or huitful, according as it
