Of Quadrupeds. 
Colon, a i 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. Gliffon, in (peaking of the Stomachs of 
Quadrupeds, faith, That a Rabbit and a Horfe have a double 
Caecum. His words are thefe ; In Equis, Cuniculis, E? Por- 
cellis Indicts, C<ecum duplex deprebenditur. But herein he 
is miftaken. As to a Rabbit, die 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 a cum, which I have above defcribU 
The Third Gut, is the Colon. The unufual (hape, and pro¬ 
digious Amplitude whereof, might give occafion to the 
Doctor to miftake it for another Caecum. So that although 
a Horfe hath but one fingle Caecum ; yet may he not impro¬ 
perly be faid to have a Treble Colon ; fc. Two Ample ones, 
next the Ccecum 5 and a fmaller one next the Reclum. Un- 
lefs any pleafe rather to call the two Great ones, the two 
BELLIES of one and the fame Colon. 
The Firft Belly next the Caecum, is no lefs where wideft, 
than 4 of a yard over 5 and in length, above a yard and k 
The Second Belly,next the Rettum ,as wide as the former j 
and above a yard long. So that each of thefe Bellies are 
digger than the Cczcum . That next the Cdtcuvi half as big 
again : And about four times as big as the Stomach. 
Thefe two Bellies are joyn’d together by a Neck., about 
Our inches over, and * of a yard long. Gather'd hkewife 
into Cells, as all the other parts of the Colon. But with four 
Ligaments, as th cC cecum. By which alfo they lie fquare. 
And upon a palling view, might be another occafion of the 
foremcntioned miftake. So that if any one fhall call either 
of thefe Bellies, a Caecum 5 then a Horfe will not have two 
only, but three Ccecums. But thefe Bellies have neither of 
diem, the defining property of a Caecum 5 which is, To be 
pervious at one end only. 
Thefmall Colon, or the fmaller part of it, runs betwixt 
the Second Belly and the Reclum: hkewife full of Cells, con¬ 
tain d together by two oppofite Ligaments as in other 
Animals. Tis about three inches over 5 and fix yards 
long. 
The Reclum, very thick and Mufcular, as in mod other
