740 THE CRANIA OF THE MOUND-BUILDERS. 
In examining this skull in its general outlines the observer’ is 
struck by the scantiness of brain capacity, seen in the narrow fore-

instead of being continued in a straight line, as in the well-devel- 
oped European skull, curves up to the occipital crest. The occip 
ital condyles are small, and “ the basilar portion of the occipital 
bone ascends with unusual obliquity from them.” “t The foramen

grooves for the sinuses are, on the other hand, comparatively 
small.” The post-glenoid process, as in the negro, is strong 
marked. The occipital crest is highly ridged, and arched cor 
vexly like the figure m, and the point where these arches intersect
