26 QUADRUMANA. 



Of the Sanguine \Jacchus vulgaris, or Jacchus penicillatus, Geoff.]. 



The sanguine 1 seems to be a small mocock or mongoose ; in shape 

 and manner It is just the same ; and the make and structure of the 

 parts are very nearly the same ; only that I think this animal is rather 

 nearer the brute ; however, not more so than what many monkeys are 

 nearer to the brute than what some others are. So that the difference 

 in monkeys from one another is as much as what the differences are in 

 these from one another, therefore may be with the same justness made 

 one class, and the second from the human 2 . The hair, skin, and fat 

 under the skin, the same as in the mongoose. 



The hand and foot are very much like that of a monkey ; only there 

 are claws instead of nails, like the mongoose and mocock ; excepting on 

 the thumb and what answers to the great toe, there we find nails. The 

 thumb is not quite so like the human as the monkeys. 



The lungs on the right side are divided into four lobes ; on the left 

 side into two only : one of the lobes on the right side lies between the 

 heart and diaphragm, as in the mongoose or mocock, or most qua- 

 drupeds. 



The stomach is more of a globular figure than the human, having 

 the oesophagus passing in at the middle, between the two ends, much 

 as in the mongoose or mocock. 



The duodenum passes as usual, or, as in the mocock, is not covered 

 by the root of mesentery, but only adheres to the angle of the mesentery 

 and loins, becoming loose on the left side, and then it enters the colon 

 upon the right. 



The colon passes up the right side, and then crosses to the left, and 

 from thence down to the pelvis. It does not adhere to any place, but 

 is attached by means of the mesocolon, which is shorter on the right 

 just where it is going to make the transverse turn. There are two liga- 

 ments that run along the colon, one at the insertion of the mesocolon, 

 the other opposite to it. 



The length of the small guts is twice the length of the animal ; that 

 of the colon, &c. is just once the length of the animal 3 . There are two 

 pancreases ; the one answering to the human, and the little pancreas

2 [This is given exactly as written. Hunter obviously means, that in comparing 

 monkeys with brutes, or lower quadrupeds, the monkeys do not differ from each 

 other more than brutes differ from each other, and that monkeys have with their 

 differences so many similarities in common, as to show them to form one natural 

 group.]
