PHALANGISTA VULPINA. 259 



tinned into the mesocolon on the right, and which is crossed by the 

 mesentery where the ileum is going to pass into the colon : this attach- 

 ment of the ileum to the mesocolon is double. The colon passes up the 

 right side loose, having a broad mesocolon ; and, when at the upper 

 part of the mesentery, it is attached to it, as also to the descending 

 duodenum ; it gets nearer and nearer to the root of the mesentery and 

 then crosses it, being closely attached to it and to the head of the 

 pancreas ; when got to the left it becomes loose again, having a very 

 broad mesocolon, and being considerable in length, it is thrown into a 

 number of convolutions. The mesocolon on the left is attached all 

 along to the loins as far as the pelvis, where this gut may be called 

 rectum. The colon is not a very large intestine. The length of the 

 small intestine is about six times the length of the animal from nose to 

 anus : the length of the csecum is 1 foot 3 inches : the length of the 

 colon on the right side is 10 inches ; its length on the left is near 4 feet. 



The liver is divided into five lobes, besides the lobulus Spigelii : the 

 left lobe, which is commonly the largest, is in this animal divided into 

 two ; or the right portion may be considered as a portion from the 

 middle lobe : the right lobe, which is the smallest, is continued on 

 behind the mesogaster, to form the lobulus Spigelii. The gall-bladder 

 lies in a deep fissure in the third lobe from the left, not in the second 

 lobe, as commonly : there are three falciform ligaments, but none of 

 them broad, or coming far towards the edge of the liver ; one is attached 

 to the supernumerary lobe, one between it and the common middle lobe, 

 and one between the common middle and the third lobe. There seems 

 to have been no ligamentum rotundum 1 . 



The pancreas begins on the left side, by several beginnings in the left 

 and posterior attachment of the epiploon at the spleen, and even on the 

 left kidney ; it passes across the body, and its head, or right end, is 

 attached to the descending duodenum ; but it does not make a curve 

 with the duodenum. The spleen is pretty large, of a triangular form, 

 adapted to the sulcus in which it is placed. The epiploon is large and 

 loose, although not covering the intestines : it is attached to the stomach 

 forwards and towards the left, to the root of the mesentery backwards, 

 as also to the kidney and cms of the diaphragm on the left. The little 

 epiploon fills up the space between the hollow of the stomach and liver ; 

 besides which it sends down a process or doubling which attaches it to 

 the hollow side of the first lobe on the left. 



The kidneys are conglobate : there is not a great difference between
