I have done the same with the Tasmanian measurements, making the angle at the

zentrum 89'3°, and have obtained a sagittal tracing of the mean male Tasmanian 

 skull. This I have superimposed on the mean Scottish contour, making the " central 

 points exactly coincident and the glabella-lambda lines in large part so (fig. 10). 



In a second case (fig. 11)1 have superimposed on the mean Scottish skull tracing 

 the Australian, with the measurements figured by Klaatsch, and the principal
