As the anthropometric form analysis of these aboriginal heads was only 
a subsidiary object of the investigation no extensive comments upon the 
preceding figures are necessary. They are given in detail for future com- 
parison and for the benefit of fellow- workers in other parts of the world 
who have not access to Australian aboriginal material. This notwithstand- 
ing, there are one or two points to which attention may be directed. 
It has already been stated that head number two turned out to be 
useless for any observations upon the brain, but this was not discovered 
until the entire head had been sawn into sections. 
Estimated Cubic Capacity. 
The estimated cubic capacity of this head had been previously calculated 
from the peripheral measurements of length, breadth, and auricular height, 
as recommended by Lee, who says that the substitution of the auricular 
height for the more customarily employed basal height gives results of 
much greater accuracy and value. 
The formula employed for this calculation was therefore as follows : — 
Length x breadth x auricular height .. . , , . 
s i 5 — = estimated cubic capacity.
