SUPPLEMENTAL HISTORY OF MAN. Ill

 nearly confounded with the upper jaw, or, if more 

 developed, is connected only with the mere animal

 of the soul within, and form an important medium of 

 communication between man and man. The human 

 countenance in form and expression presents the 

 most complete contrast to that of brutes of e very-

Camper has assigned the want of the inter- 

 maxillary bone as one of the characteristics which 

 distinguish the human head from that of other ani- 

 mals. The upper maxillary bones of the human 

 subject are joined together, and contain all the upper 

 teeth. In other animals of the same class as man 

 they are separated by a third bone shaped like a 

 ridge, which, as it contains the incisor teeth, was 

 called os incisivum. As this bone, however, is found in
