30 QUADRUMANA. 



and is a little bent, having a narrow niesocaecum : it is not attached to 

 any part of the body. The colon is a continuation of the thick end of 

 the same size ; it is attached to the psoas muscle a little below the trans- 

 verse turn of duodenum, something similar to the human, but not near 

 so much attached ; and is not attached to the loins. 



The ascending part of the colon is attached to the right edge of the 

 mesentery, so that they lie more loose in the abdomen than in the 

 human, or even the monkey. The colon makes a turn across the spine, 

 where it is attached to the root of the mesentery, and to the duodenum 

 and pylorus ; but, in its way to the left, it becomes looser and is bent 

 back upon itself towards the right near its whole length ; that is, near 

 the beginning of colon : this bend is on the underside of the former, 

 and is fixed by a narrow mesentery. It is then bent back again upon 

 the last described part towards the left ; but not so far as the former 

 reflection, being attached to the former and root of the mesentery, but 

 not in contact with it. Then it passes back towards the spine upon the 

 left of the root of the mesentery attached to it, and to the last part of 

 the duodenum, as the duodenum passes to the left behind the mesentery : 

 then passes down the loins in the middle of the body to the pelvis pretty 

 straight. There is something ligamentous about the beginning of the 

 colon and termination of the caecum, which makes it a little pouched 

 there, but nowhere else ; and here it is much the largest. There are 

 no valvulae conniventes in the small intestines. The length of the small 

 intestines is three times the length of the body of the animal ; but not 

 one and a half of the body and tail : the length of the colon is about 

 one and a half of the length of the body 1 . The epiploon is pretty broad, 

 a good deal like a dog's ; it is attached to the whole of the great arch 

 of the stomach, to the colon upon the right of its posterior lamella, and 

 on the left of that, to the spleen and pancreas. 



The liver is divided entirely into two lobes ; but the right of these 

 is subdivided into four, which may be called five lobes in the whole, if 

 we count in that way : the left is the largest, and so on less and less to 

 the right, which is the smallest, and is partly behind the mesogaster, 

 and may be said to be the lobulus Spigelii, as is the case in many other 

 animals. The ligamentum rotundum passes into the sulcus between 

 the second left of the four lobes. The gall-bladder is between the 

 middle of the four lobes, so that there are two on each side of it belong- 

 ing to the large right lobe. The gall-bladder lies in a sulcus of the 

 liver, contrary to the common manner, for the fundus lies forward or 

 toward the diaphragm, and is in view upon the convex side of the liver ;
