Of Quadrupeds. 
i 
Colon, a * of a yard over. And in length, a full yard. So 
that it is more than twice as big as the Stomach. 
The Learned Dr. Glijfon, in fpeaking of the Stomachs of 
Quadrupeds, faith, That a Rabbit and a Horfe have a double 
C cecum. His words are thefe 3 In Eqim, Cunicul'vs, & Tor- 
cellis Indicts, C cecum duplex deprehenditur. But herein he 
is miftaken. As to a Rabbit, the contrary hath been feen in 
the Guts prefented entire before this Honourable Prefence. 
And who ever will take the pains to examine all the Guts of 
a Horfe, will find, That neither hath he, any more than 
One C cecum, which I have above defcrib'd. 
The Third Gut, is the Colon. The unufual fhape, and pro- 
digious Amplitude whereof, might- give occafion to the 
Doctor to miftake it for another Cacum. So that although 
a Horfe hath but one fingle C cecum 3 yet may he not impro- 
perly be faid to have a Treble Colon 3 fc. Two Ample ones, 
next the C tecum 3 and a fmaller one next the Retlum. Uri- 
lefs any pleafe rather to call the two Great ones, the two 
BELLIES of one and the fame Colon. 
The Firft Belly next the C cecum, is no lefs where wideft, 
than ^ of a yard over 3 and in length, above a yard and 
The Second Belly ,next the Re£tum,as wide as the former 5 
and above a yard long. So that each of thefe Bellies are 
bigger than the Caecum. That next the Ccecum half as big 
again : And about four times as big as the Stomach. 
Thefe two Bellies are joynd together by a Nec'k^, about 
four inches over, and *of a yard long. Gather d likewife 
into Cells, as all the other parts of the Colon. But with four 
Ligaments, as the C cecum. By which alfo they lie fquare. 
And upon a parting view, might be another occafion of the 
forementioned miftake. So that if any one (hall call either 
of thefe Bellies, a C cecum 3 then a Horfe will not have two 
only* but three C cecums. But thefe Bellies have neither of 
them, the defining property of 2lC cecum 5 which is, To be 
pervious at one end only; 
The fmall Colon, or the fmaller part of it, runs betwixt 
the Second Belly and the Reftum : likewife full of Cells, con- 
tain'd together by two oppofite Ligaments as in other 
Animals. 'Tis about three inches over 3 and fix yards 
long. 
The Retlum, very thick and Mufcular, as in mod other
