among the higher mammals and may well be expected to show some 
groupal differences in man. It yields itself to three measurements, 
the maximum length, breadth, and height, from which in turn we 
obtain the module or mean diameter, useful in comparing the size 
of the bone, and the breadth-length and breadth-height indexes, 
which show its shape. 
There are 60 astragali in the Munsee material, and the measure- 
ments of 52 paired bones are given below. They show the bone in 
the male to be absolutely larger in every dimension than in the female. 
As to the side, there is practically no difference among the males, but 
among the females the average measurements of the left astragalus 
are all slightly higher than those of the right bone. The module is 
practically identical on the two sides in the males, and slightly higher
