thougli it presents a loWj narrow, and but little capacious fore- 

 head, might still, according to Huxley's opinion, have belonged

 line which both skulls show as regards the curvature, we find 

 that it agrees to a considerable extent.

This line ascends gently and uniformly from the frontal pro- 

 minence to the vertex, which Hes further back, nearly above 

 the mastoid process. From this vertical spot the curve de- 

 scends backwards in the same oblique Hue. The mode of 

 formation is exactly the same in both, though the height of 

 the arch is much greater in the Engis skull. But these pecu- 

 lianties find their analogues when we compare larger series of 

 skulls of both sexes belonging to the same race.
