Tasmanian work, and to which the reader is referred. These, it will be 
remembered by those who have seen that work, are the data employed 
by Schwalbe in his examination of the Pithecanthropus, Spy, Neandertal, 
and other calvaria. To these 27 observations there have been added, in 
the case of the Australian, 5 other observations employed by Klaatsch 
(7), as follows : — 
A. The nasio-inion length. 
B. The glabella-lambda length. 
C. The lambda-glabella-inion angle. 
D. The distance of the bregma foot-point from the glabella on the 
glabelladambda line. 
E. The bregma foot-point-glabella-lambda index — that is, the proportion 
which the distance of the bregma foot-point from the glabella 
on the glabella-lambda line bears to the glabella-lambda length, 
the latter being taken as 100. 
The complete series of measurements employed will be readily seen 
in fig. 1. 
In addition to the foregoing 32 observational points of the form analysis 
of the Australian aboriginal skull, we have also recorded and employed for 
purposes of comparison a second series of ordinary craniological observa- 
tions as follows : — 
1. Maximum cranial length. 
2. Maximum cranial breadth. 
3. The cephalic index. 
4. Cranial height. 
5. The height index. 
6. The basi-nasal length. 
7. The basi-alveolar length. 
8. The alveolar index. 
9. The nasal height. 
• 10. The nasal width. 
11. The nasal index. 
12. The orbital width. 
13. The orbital height. 
14. The orbital index. 
The necessary figures for the above in the cases of the Australian and 
Tasmanian have been obtained from our own original material. In the 
cases of the Andamanese Islanders and the modern Italians they have been 
obtained from the Catalogue of the Royal College of Surgeons of London.
