 the alveolar process absorbed, and the mental process 

 pointed and prominent. 



The skull is an ovoid structure with a flattened and 

 irregular base. It consists of two portions, the cranium 

 and the face. In the adult male these two are of nearly 

 equal proportions ; in infancy the cranial portion is nearly

 cranium constitutes about three-fifths and the face two-

 of the inferior maxillary, immovably articulated together, 

 and comprise the synarthrodial joints. On the surface
