Anthropometric Measurements. 
In dealing, in the first place, with the external anthropometric measure- 
ments it may be stated that these were recorded with the most modern and 
approved instruments upon the heads prior to their being cut, and that the 
measurements so recorded are those of the Monaco International Commission 
so far as they go, and of the British Association for the Advancement of 
Science. In connection with these measurements a third Australian 
Aboriginal head was available, but was not suitable for the examination of 
the brain, as the hardening process had not been completely successful. 
This third head was that of a male from New South Wales, and in the 
accompanying list of measurements is numbered two.
