CERVXJS TARANDUS. 14B 



Of the Rein-Deer [Cervus tarandus, Linn. 1 ]. 



The stomach is attached pretty much to the diaphragm. There are 

 four cavities, pretty much the same as in black cattle. The lower part 

 of the first cavity [rumen] is forked, viz. right and left ; the left of these 

 two terminations is the shortest and smallest. The villi of the first 

 cavity are very long 2 . 



The seeond is the honeycomb cavity [reticulum], but the cells are 

 not deep. 



The third cavity, or ' parson's-book ' [psalterium], is much as in the 

 other common ruminants. The fourth, or true stomach [abomasus], has 

 the same shape [as an ordinary stomach] and some longitudinal rugse, 

 as is common in this class. 



The contents were finer and firmer in each stomach [as seen from the 

 first to the fourth] : they were very green in the first three cavities ; 

 but were more of a yellow colour in the fourth. "Whether this was 

 owing to the bile, or to the vegetable substance having become yellow 

 by the gastric juice, I do not know. 



The duodenum near its beginning makes a slight fold upon itself; 

 then passes down the right side attached to the first ascending part of 

 the colon ; then crosses the body obliquely upwards behind the mesen- 

 tery along with the colon, where that gut passes to make its turns on 

 the posterior surface of the mesentery. 



The duodenum ascends as high on the left as its beginning on the 

 right ; it then attaches itself to the edge of the mesentery, along which 

 the small intestine passes downwards and towards the right again, 

 making very short convolutions on that membrane ; and before it enters 

 the colon on the right, it rises higher in the abdomen; the whole 

 making a round sweep 3 . 



The caecum is a long and almost straight gut, situated on the right 

 and lower part of the abdomen, with its blind end in the pelvis. Its 

 length is about a foot and a half. A continuation of the same gut or colon 

 passes up the right side as high as the liver ; then bends quickly back- 

 wards and down, and a little towards the right upon itself, attended by 

 the duodenum ; and when got pretty low again it passes across the 

 spine towards the left, and upwards behind the root of the mesentery ; 

 and then begins its spiral turns on the posterior surface of the mesen-
