ANATOMY AND PHYSIOLOGY 
part remains in the oesophagus till the rest is digested* 
The epiploon, on the whole, is a thin membrane ; on the 
right side it is rather a thin net- work, though on the left 
it is a complete membrane, and near to the stomach of 
the same side becomes of a considerable thickness, espe- 
cially between the two first bags of the stomach. It has 
little or no fat, except what slightly covers the vessels 
in particular parts/’ 
OF THE LIVER, PANCREAS^ AND SPLEEN. 
There is a considerable degree of uniformity in the 
liver of this tribe of animals. In shape it nearly resem- 
bles the human , but is not so thick at the base nor so 
sharp at the lower edge, and is probably not so firm in 
its texture. 
The liver, towards the left, is very much attached to 
the stomach, the little epiploon being a thick substance. 
There is no gall bladder ; the hepatic duct is large, and 
enters the duodenum about seven inches beyond the 
pylorus® 
The pancreas is a very long flat body, having its 
left end attached to the right side of the first cavity of 
the stomach. It passes across the spine at the root of 
the mesentery and near to the pylorus, joins the hollow 
curve of the duodenum, along which it is continued, and 
adheres to that intestine, its duct entering that of the 
liver near the termination in the gut. The spleen is 
involved in the epiploon, and is very small for the size 
of the animal.”
