Orifice of the Stomach ; and tl^t whereby it difcharges 

 itfelf into the Duodenum^ its right or lower Orifice. 



The Stomach is round, and fomewhat (j^jyg stomiuh 

 long, refembling a Bagpipe, but more capa- 

 cious on the left Side than the right ; its Magnitude is, 

 generally fpeaking, more cr lefs, according to the Size of 

 the Horfe. It is alio compofed of three Cafes, the outer- 

 molt of which feems to rife from the Feritondsum ; the 

 fecond is mufcular and flefliy ; and the laft a Continua- 

 don of the innermoll Coat of the Gullet. 



It has Arteries from the Cctliacal Branch j^^ ^^^^ 

 of the Aorta^ and Veins from the SpJenick^ -"^ 



and the Gajiricks^ a Vein common to its left Side and 

 the Caul, and one common to the Caul and the right Side 

 from the Mejentericks', and laftly, the Pyloria^ which 

 comes from the Porta, 



It has Branches from the Recurrent j ^ 

 Nerves, which being exceeding numerous, ^ ^"^ 

 are the Occafions of its being fo very fufceptible of Han- 

 ger, and ail other Senfations. 



The Ufe of the Stomach is to concod j jj. 

 and digeft the Aliment, fo as to render it fit ^ •^'^* 

 for Nourifhment; and this is performed chiefly by its 

 mufcular Motion, which is manifeft from its Strudure, 

 and the Power it has of contrading itfeif into thofc Riigcs^ 

 which we difcover in it when it is empty. 



After the Stomach come the Guts^ which, cj-j ^ 

 according to Mr. Snape's Computation, are 

 in number fix, to wit, the fmall Gut, the Cacum or blind 

 Gut, the three Colons^ and the ftreight Gut.- 



The /mail Gut (which in a Man is divid- ^, ^ ,, ^ ^ 

 ed into three, to wit, the Duodenum, Jeju- ^^' J"""^^ ^«'- 

 num^ and //i^«, from its feveral Circumvolutions) is in a 

 Horfe reckon'd to be about 26 Yards in length; and is in 

 all its Turnings fallen'd to the Mefentery. The Stomach 

 empties its Aliment into this Gut, v/hich is furnifh'd with 

 an infinite number of milky Veflels, call'd La^eah^ that 

 receive the finer Portion of the Aliment, which being con- 

 vey'd by thefe little Conduits acrofs the Mefentery^ to one 

 common Receptacle, afcend upwards along the Spine, 

 thro* a pretty large Chanel, which is call'd the Thoraick 

 tDu5f \ and from thence into the Veins, and is incorporated 

 with the Blood. The coarfer Part of the Food, by a peri-
