4. Heights of the vault: 



(a) The basilo-bregmatic height; c.e. 



Landmarks: Inferiorly — the basion, or median point of the anterior 

 border of the foramen magnum (avoiding the exostoses that are some- 



FlG. 1 



times found at this place); superiorly — the bregma, or median point 

 of the coronal suture. 



(b) Auriculo-bregmatic height {H, fig. 1).' 



This is the distance between the bregma and a line connecting the 

 superior borders of the auditory meatus. 



Landmarks: Inferiorly — the point where the imaginary line uniting 

 the superior borders of the two meatus auditorius intersects the median 

 part of the skull ; superiorly — the bregma. 



5. The smallest frontal breadth or minimum frontal diameter, e.g. 



This is the shortest horizontal diameter between the two temporal 

 crests on the frontal bone. 



6. The maximum frontal breadth or maximum frontal diameter; e.g. 

 This is the largest horizontal diameter of the frontal squama (the 



bistephanic diameter of Broca is abandoned). 



7. Maximum bimastoideal diameter (m.m. fig. 2) ; c.e. 



Landmarks: The external surface of each mastoid process at the 

 level of the center of the meatus auditorius. At this level search with 

 the spreading compass for the maximum diameter. 



8. The maximum bizygomatic diameter; e.g. 



Landmarks: The most widely separated points on the external sur- 

 face of the zygomatic arches. The object is to find the greatest diam- 

 eter.
