10 QUADRUMANA. 



The duodenum is only seen a little before it passes through behind 

 the mesentery ; it is attached to the back below the passage of the 

 duodenum, although not quite so low as in the human. 



An appendix caeci about 3 inches long 1 . The caecum is not at- 

 tached, nor is the ascending colon, to the loins, but to the right edge 

 of the mesentery as they pass up. At last the colon is attached to the 

 kidney, and then to the duodenum, where they cross one another to go 

 across the spine : as the colon passes down on the left side it makes a 

 turn or fold upon itself, which may be called the sigmoid flexure, only 

 here it is higher than in the human ; however, the pelvis going higher 

 may be one reason. No valvulae conniventes. The pancreas much as 

 in the human. The uterus, &c. lay in the pelvis, like a child's. 



[The Green Monkey (Cercopithecus Sabceus, Geoff.).] 



In a pretty large she monkey of a dun colour mixed with green : — 



The colon did not adhere anywhere but at the beginning of the 

 transverse arch, and had a very broad mesocolon everywhere excepting 

 at the beginning of the arch, where the adhesion was. There was no 

 particular sigmoid flexure. 



The oesophagus is longer below the diaphragm than in the human. 



The liver does not adhere so firmly as in the human, or by so broad 

 a surface. 



The clitoris is situated much as in the human : there are no nymphre. 

 The meatus urinarius is much as in the human. The os tincae is promi- 

 nent and rough with rugae ; within the os tincaa are two prominences, 

 a lower and an upper, the highest is the largest 2 ; from thence upwards 

 the uterus becomes very small, and there dilates into the fundus, which 

 becomes thinner in its coats towards the end, and terminates in two 

 rounded comers which project a little further than the middle between 

 them, which is one beginning step to the quadruped. 



In a he one of the same kind 3 , the liver was divided into four lobes ; 

 the left was small and most detached, the right was but very little 

 detached, and passed in to make the spigelian lobe. 



The little epiploon is more membranous and not so loose as in the 

 human. The thyroid gland does not unite before the trachea. The 

 arytenoid cartilage has two small cartilages standing upon it, which 

 makes two points. The os hyoides does not go to the head as in many 

 brutes, but approaches nearer [in form to that of] the brute. Yery

 in man.]
