PROFESSOR SIR WILLIAM TURNER ON 



of the constituent parts of the Scottish skulls studied in this memoir, I have prepared 

 Table XVI., in which I have stated for both sexes the maximum and minimum dimen- 

 sions, as well as the mean of the principal measurements in the series of skulls, together 

 with the maximum, minimum and mean of the respective indices. I have also, by way 

 of comparison, included in the Table the mean diameters and indices of a number of 

 skulls of male aboriginal Australians which I have measured.

Sagittal Sections. 



In my Challenger Report, 1884, I gave a figure of at least one characteristic speci- 

 men of each group of aboriginal skulls, in which a skull had been bisected longitudinally 

 and vertically immediately to one side of the septum nasi and the mesial plane of the 

 cranial cavity, and in Part II. of the memoir on Indian Crania I produced two figures of a 

 similar kind. In my description of these figures in the Challenger Report I stated that 

 I was in accordance with Professors Huxley * and Cleland t in regard to the import-
