external angular process, modern man is rather more 
simian than Piltdown man. 
Having thus established a base line from which we can 
work, we are now in a position to reconstruct and inter- 
pret the lateral aspect of the Piltdown skull. We shall 
see what this ancient man looked like when his head was 
viewed in profile — the most instructive of all views to a 
student of anthropology. The points needed for a base 
line — the external angular process and posterior interior 
angle of the parietal bone — are preserved and can be

of the right frontal region of a modern skull, to show the relationship of the 
external angular process to the third frontal convolution. 
defined with precision. It was also on this base line that 
the experimental reconstruction, described in the previous 
chapter, was carried out. That experiment throws a clear 
light on the nature and dimensions of the Piltdown skull, 
and hence it is necessary for us to return to it once more. 
In fig. 141 are shown drawings of the original Egyptian 
skull and of the reconstruction as seen from the side. The 
reconstruction reproduces the height of the original with 
exactitude ; in both, the vault rises just above the upper 
limit of the frame, and is thus a little more than lOO mm. 
(102 mm.) above the base line. The upper margin of
