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

 inion line from either the same or by direct measurement.

[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].
