length-height, as seen from the side (norma lateralis); and the 

 breadth-height, as seen from behind (norma occipitalis)]. 



calvarial height [48] X IOC 



5. Calvanal height index ; ~ ~ roo1 



nasion-inion line [33] 



The calvarial height is to be taken from the craniogram; the nasion- 

 inion line from either the same or by direct measurement.

6. Bregma position index -. ^-. =^r- 



nasion-imon line [33] 



[The lesser the index the farther forward the bregma, and conse- 

 quently the higher the position of the frontal bone. The upper 

 measurement is taken from the craniogram; the nasion-inion line 

 from either the same or by direct measurement].
