Taking the dimensions of the fossil cranium into consideration, 
the deviations from the Australians and Tasmanians are mostly slight. 
Then the glabella-inion length, just as the glabella-lambda chord, 
presents in proportion to the maximum cranial length, the closest 
agreement with the Tasmanians, the calvarial height index with the 
Australians. Both the glabella-lambda line and the glabella-inion line 
are, with regard to the maxium cranial length, shorter in Tasmanian 
and in Wadjak I than in the Australian. This is in connection with 
the bulging out of the occiput. The latter is still more strongly 
pronounced in Wadjak II, so that the lobus occipitalis of the 
cerebrum ended more or less pointed. 
An important difference consists in this that the top of the calva- 
rial height (N°. 7 of the Table) lies relatively much more dorsally 
in the fossil man of Wadjak I than, on an average, in those recent 
races, particularly the Australian race. This means that the frontal 
part of the cranium was comparatively low vaulted, which also 
appears from the smallness of the index of frontal curvature (N°. 16), 
and the considerable value of the angle of frontal curvature (N°. 22). 
It is noteworthy that in all these respects the fossil cranium comes 
as near, or nearer, to that of the Tasmanian as to that of the 
Australian. 
The comparatively lesser development of the frontal part of the 
cranium may also be inferred from the measure of the minimum 
frontal breadth; this is only 99 mm. for the Wadjak craninm, with 
a maximum length of 200 mm. (in the second cranium, which was - 
certainly still longer, 101 mm.), while in Australian crania the 
maximum is 104, and the mean 98, according to Duckwortn’s 
measurements, and Turner even met with a maximum of 108. 
This latter went together with the greatest capacity found by TurNER 
in Australian crania, 1514 cm.’ ’). 
This relatively lesser development of the frontal part must have 
an unfavourable influence on the capacity of the cranium, as actually 
appears in the capacities of Australian crania, found by direct 
measurement. 
Nor may the unfavourable influence on the capacity of the roof- 
like elevation, in comparison with equally high crania with rounded 
vault, observed in Australian crania, be neglected, when the capacity 
of Wadjak I has to be estimated, though it cannot be very great here.

of Human Structure. Toronto Meeting of the British Association for the Advan- 
cement of Science) TURNER had not found a greater capacity among 63 Australian 
skulls than 1514 cm? of that cranium of Port Curtis in Queensland.
