the Guts, falls downwards, and is difcharg'd in Excrement. 

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

 mon with the rcll, 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, ^c. 



The next is the Blind Gut^ which has 

 7he Carcum sr but one Paflage for the Excrements, fo that 

 blind Gut. they are forced lo return back thq fame way 



ihey went in. 

 *rhe Three The three Colons (which In Men are but 



Colons. 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. Thb Gut 

 is drawn up into many Purfes or Cells by two Ligaments, 

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

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

 its beginning, hinder the Excrements, either from returning 

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

 before the Chyle or milky Subftancc is fufficiently prepar'd 

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

 to be inrtead of a Valve, lo hinder the Aliment or Chyle 

 from falling too foon downwards into the Colony for if 

 it was notln fome meafure obllru(f^ed, and detained in its 

 Paflage through thefe large Conduits, the Body could ne- 

 ver be fufficiently fupplied with Nourifhment. The firft 

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

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

 or ftrcight Gut, near fix Yards long. 



The Streight Gut, which goes ftreight 

 The Streight downwards to the Fundament, is not above 

 ^"*' half a Yard in Length ; its Coats are thicker 



than thofe above defcribed, its middlemoll being^ very 

 fiefliy and mufcular : At its Extremity there is a Sphin- 

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

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

 Times. 



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

 llimy Matter, which preferves them from being hurt, either 

 by the Hardnefs of the Excrements, or the Pungency of 

 any (harp corrofive Humours •■, for they being, as mod 

 other membranous SublUnces, full of Branches of Nerves, 

 would be in perpetual Pain, had not Nature t^ken A fpecial 



Caic of them.
