tfie Guts, falls downwards, and is diTchargM in Excrement 

 There are in this Gut, befides the Vellbis it has in com- 

 mon with the relt, two Duds which open into it; the one 

 from the Liver, and the other from the Sweetbread ; each 

 of which fends in a Juice, that contributes to the Refine- 

 ment of the Aliment, ^r. 



The next h the Blind Gut, which has 

 Jfe C^cum or but one PalTage for the Excrements, fo that 

 mina ^ut. , they are forced lo return back the fame way 



they went in. 

 ne Thm The three Colons (which in Men are but 



^.oions. one continued Gut) are next the blind Gut ; 



they are divided into three Guts by two 

 narrow Necks of about half a Yard in Length. This Gut 

 IS drawn up into many Purfes or Cells by two Ligaments 

 one of which runs along the upper fide, and another alona 

 the under fide ; which with the Affiftance of a Valve at 

 its beginning, hinder the Excrements, either from returnin^^ 

 back into the fmall Guts, or falling too foon downwards"" 

 before the Chyle or milky Subftancc is fufficiently prcpar'd 

 and fent off into its proper Veflels. The Cacum feems alfo 

 to be inllead of a Valve, to hinder the Aliment or Chyle 

 from falling too foon downwards into the Colon ; for if 

 U was not in fome meafure obltruded, and detained in its 

 Paflage through thefe large Conduits, the Body could ne- 

 ver be fufficiently fupplied with Nourifhment. The lirft 

 of thefe Colons is about a Yard and half in Length ; the 

 fecond about a Yard ; and that which joins to the Return 

 qr ftreight Gut, near fix Yards long.

 Gut> downwards to the Fundament, is not above 



♦T, ^. r . ^^^^ ^ ^^^^ ^" Length ; its Coats are thicker 

 than thofe above defcribed, its middlemoft being very 

 «elhy and mufcular : At its Extremity there is a Sphin- 

 cter, which dilates itfelf for the Evacuation of the Ex- 

 crements, and keeps it contraded, or fhut up, at all other 

 i imes. 



There is on the Infide of the whole Guts, a Mucus, or 

 liimy iV^tter, which preferves them from being hurt, either 

 bj the Hardnefs of the Excrements, or the Pungency of 

 any Iharp corrofive Humours ; for they being, as moll 

 other membranous Subftances, full of Branches of Nerves, 

 would be in perpetual Pain, had no.t Nature taken a fpecial 

 Care of them. ' ^
