BONES OF THE CRANIUM 



The CRANIUM, or brain-case, is small as compared with that of man, and 

 occupies less than one-fourth of the whole head. It is made up of nine 

 bone.s, three of which are pairs and three single ones. These bones are 

 in most parts made up of two tables, with a cellular structure interposed, 

 called the dijilue, which is in certain situations expanded into large cells, as 

 in the frontal sinuses. They are connected together bj' serrated sutures, 

 except where the temporal bone overlaps the parietal, and in that situation, 

 on each side the *iVnll ^me thin scale Csquama) overlaps the other. The two
