140 RUMINANTIA. 



over the root of the left lung, and enters the right auricle as the super- 

 numerary vena cava does 1 . 



The Hog-Deer, from the East Indies [Porcine deer of Pennant 

 (Cervus porcinus, Zimm.)]. 



The one from which I take this description was a male, castrated. It 

 was not so large as our doe, but much the size of the roebuck in Scot- 

 land; also much the same colour. It had no horns, but that was 

 probably owing to its having been castrated. The eyes were rather 

 hollow, which gave it an old look. The ears were large, thick, especially 

 at the root, and pretty broad, much larger than our deer's. Its mouth 

 and the nose were rather flat laterally. The tail was short. 



The stomach is very similar to those of other ruminating animals. 

 The duodenum passes down the right side, behind, and a little more to 

 the right than the ascending part of the colon. When got pretty low 

 down it bends upwards upon itself, and then crosses the spine obliquely 

 upwards, towards the left and a little forwards, passing pretty high 

 before it becomes loose : it then forms the jejunum, which is strung 

 along the left edge of the mesentery, wbich mesentery is rather narrow. 

 On this course it is rather getting" towards the right, or perhaps the 

 middle line of the body, and its lower part may be called ileum. This 

 gut winds round the lower end of the mesentery, and gets on its right 

 edge passing up before the spiral turns of the colon, and gets alongside 

 the caecum, into which it enters on its left side. This last part is pretty 

 straight. 



The caecum was rather higher than common, but probably this was 

 owing to its containing but little. It terminates in the colon, which 

 passes up the right to the crossing backwards of the beginning of the 

 duodenum ; then would seem almost to bend down the right side along 

 with that gut, or between that gut and the caecum. It then bends 

 back behind this descending turn, and passes towards the left and a 

 little upwards behind the root of the mesentery, and begins to make 

 spiral turns on the posterior surface of this membrane ; when, having 

 made two complete turns, which are from the circumference towards a 

 centre, it is gently bent back upon itself, in between the former turns, 

 forming two complete turns or rounds back including the one that keeps 

 near to the edge of the mesentery, which might be called a straggling- 

 one. The colon then passes towards the right, behind the root of the 

 mesentery, following nearly back again its first turns along with the
