In the above table columns (i) — (v) give absolute measurements, (vi) — (xi) 
provide indices and (xii) the "bregmatic angle," or angle the base line makes with 
the line joining nasion or glabella to bregma. It has been suggested that this angle 
measures in some manner the flattening of the frontal. It seems to us incapable 
of really determining the grade of primitiveness in the cranium. Other things 
being equal this angle will merely measure the extent to which the bregma is 
thrown back on the cranial vault, a relatively large frontal bone will in itself 
produce a small bregmatic angle. This is seen at once by comparing the relative 
position of the bregma as measured by the index xjBo for the bregma (column (ix)) :
