A comparison of these indices would appear to show that in the Bush- 
man the bodies of the vertebrae were relatively narrower in their antero- 
posterior length and deeper in their vertical depth than in the European 
by about 5 per cent, in each case. The vertebral foramen is relatively 
longer in the Bushman, thus corresponding with the length-breadth index 
of the skull, which gives an indication of the relative dimensions of the 
cranial cavity. 
Of the other parts of the Bushman cervical vertebrae the non-bifid and 
less obliquely inclined spinous processes are distinctive, while the inter- 
locking arrangement of the bodies appears to be somewhat poorly developed 
as compared with those of the European.
