ON THE ANATOMY OF THE 



lous, and open upwards, which would be inconve- 

 nient, did the animal usually assume the erect 

 posture. The projection of the jaws is exces- 

 sive; and though much less so than in the ba- 

 boon, yet the profile of the face is concave. It 

 may be remarked, however, that the projection 

 of the lower jaw is caricatured in the first and se- 

 cond figures of Camper's second plate. The mouth 

 is wide, the lips rather thin, and destitute of that 

 recurvation of the edges which add so much to the 

 expression of the human countenance. The whole 

 contour of the head bears no inconsiderable re- 

 semblance to some Egyptian figures of the god 

 Anubis. 



The spread of the shoulders is distinctly marked ; 

 but the width of the lower part of the chest is pro- 

 portionally greater when compared to the upper, 

 than in man. The mammae in our subject are 

 perfectly fiat, and the nipples very small, as is al- 

 so the umbilicus. 



From the lower ribs, the diameter of the abdo- 

 men decreases rapidly to the loins, where the ani- 

 mal is peculiarly slender ; — a circumstance in which 

 it approaches the other simise. The pelvis appears 

 long and narrow ; another approximation to the rest 

 of the genus. The genitals present striking pecu- 

 liarities, which shall be afterwards particularly de- 

 scribed. There are no callosities on the buttocks. 



With regard to the limbs, the chief difference 

 between our specimen and Dr Tyson's figure, con-
