 these processes in man, have a different origin.) The 

 bones of the nose were placed perfectly flat on the 

 face, so as not to be visible in the profile of the skull, 

 and the triangular opening was circular. The supra- 

 maxillary bones projected considerably beyond the 

 remarkable orbiter process of the frontal bone, being 

 the form of the lower part of the bone nearer to that 

 of quadrupeds. The lower jaw was stronger and 

 narrower." 



The superior maxillary bones in man are united to 

 each other, and contain the whole of the upper teeth ; 

 but in most of the mammalise, they are separated by 

 a third bone of a wedge shape, which contains the 

 incisor teeth. Blumenbach named this the os inter- 

 MaxilZare. According to that anatomist, and Camper, 

 it is found in the red orang; whereas, according to 

 Tyson and Daubenton, it was not seen in the chim- 

 panzee, or black orang ; nor does Dr Trail mention 

 having observed it in the specimen which he dissected. 

 " The brute face," says Lawrence, " is merely an 

 instrument, adapted to procure and prepare food, and 

 often a weapon of offence and defence. The human

 index of what passes in the busy world within. In
