ability) to be the transverse diameter of the left tibia. The seriation 
tables for this diameter may be summarised as follows :—

The frequencies for the left tibia clearly explain the greater value 
of the corresponding coefficient, and suggest the presence of two 
strongly contrasted types of bone. Such asymmetry has not been 
recognised previously. 
[Pre-dynastic Egyptians present the same feature; thirty right 
tibizs yield me a mean index of 66, against 64 for thirty left tibie.] 
The index of Platycnemia!’ next calls for consideration. And it 
will be noticed that on the average the left bone provides a lower index 
(64°84) than does the right (66°03). This difference between the right 
and left bones may be further emphasised by the following summary 
of the seriation tables :—

Turning to the comparison of the prehistoric Cretan bones with 
those of other localities and races, I find the materials collected by 
Professor A. Thomson and Professor Manouvrier suitable for my pur- 
pose. From the data supplied by them,?* I have drawn up the follow- 
ing list, introducing my Cretan and Egyptian data.

The prehistoric Cretan bones are observed to fall among the pre- 
historic representatives of other types, and they are not far removed 
7 Platycnemia is distinct when the index is below 69, and it is very marked when 
the index is below 63.
