Concerning the A ^ J ^^^ ^^°^J Defcriprion of 

 Blood Vejfeh and f\ ^hc Parts which compofe and 

 Circulation of "^ "^^ make up the Body of a Horfe, 

 the Bloody ^c, it cannot be thought unneceflary to add 

 fome Things in general, concerning the 

 Way and Manner by which an animal Body is fultained 

 and nourifhed, and thereby render'd fit to perform the feve- 

 ral Functions of Life. I Ihall therefore fum up this Abridg- 

 ment with a brief Account of iht Circulation of the Blood, 

 and its Diftribution into all Parts of the Body. And in 

 Order thereunto, I fliall not only ftudy Brevity, but endea^ 

 vour to make the Difcourfc as eafy and intelligible as pof- 

 fible, beginning with the Aliment, and throughout the 

 whole following the Order of Nature ; that thofe who have 

 not had the Opporiunitics of Study, may reap feme Benefit 

 by It. 



The Chyle ^^ ^^^^ ^^ ^" Animal gathers lA his Food, 



the Glands of the Mouth pour forth their 

 Liquor, not only that it may be the more eafily chew'd, 

 but that it may be thereby render'd foft, and more readily 

 p:\fs through the Gullet into the Stomach. When it has 

 arrived there, feveral Inftruments become afliftful to Di- 

 geftion. The Juices which flow from the Glands of the 

 Stomach, and the Drink, help to keep it moift ; fo that 

 by the continual Action of its Sides, which, by virtue of 

 its mufcular Fibres, perpetually rub one againft another, 

 and by the AfTiilance of the mclofed Air, all the Parts 

 and Particles of the Food are greatly feparated. The 

 groller Parts are carried downwards by the Periftaltick 

 Motion of the Guts, the Prellure of theMidrifT, and Muf- 

 clesof the lower Belly, and are voided at the Fundament, 

 while the finer Parts conilitute that white milky Sublbnce 

 which we call Chyle*
