410 Mr. Hunter’s Obfervations on the 
its quick turn, and terminate near the anus. The colon and 
rectum have the rugae very flat, which feems to depend in- 
tirely on the contraction of the-gut. 
The reCtum near the anus appears, for four or five inches, 
much contracted, is glandular, covered by a loft cuticle, and 
the anus fmall.

I never found any air in the inteftines of this tribe; nor 
indeed in any of the aquatic animals. 
The mefenteric artery anaftomofes by large branches. 
There is a confiderable degree of uniformity in the liver of this 
tribe of animals. In fihape it nearly refembles the human, but is 
not fo thick at the bafe, nor fo fharp at the lower edge, and is 
probably not fo firm in its texture. The right lobe is the largeA 
and thickeft, its falciform ligament broad, and there is a large 
fiflure between the two lobes, in which the round ligament 
pafles. The liver towards the left is very much attached 
to the Aomach, the little epiploon being a thick fubAance. 
There is no gall-bladder; the hepatic duCt is large, and enters 
the duodenum about feven inches beyond the pylorus. 
The pancreas is a very long, flat body, having its left end 
attached to the right fide of the firA cavity of the Aomach : 
it pafles acrois the fpine at the root of the mefentery, and near 
to the pylorus joins the hollow curve of the duodenum, along 
which it is continued, and adheres to that intefline, its duCl 
entering that of the liver near the termination in the gut. 
Although this tribe cannot be faid to ruminate, yet in the 
number of Aomachs they come neared: to that order; but here 
I fufpeCl that the order of digeftion is in fome degree inverted. 
In both the ruminants, and^iis tribe, I think it mull be allowed 
that the firA Aomach is a refer voir. In the ruminants the pre- 
cife ufe of the fecond and third Aomachs is perhaps not known ; 
but
