the Burmans betweeii the modern Europeans and the primitive races dealt with 
in the table compiled by Thomson*, whereas Group C comes in the middle of the 
primitive list ; this will be discussed laterf . Of the remaining features that exhibit 
significant differences in the means of the two groups, I need only refer to the 
transverse arc from auricular point to auricular point over the apex {Q' and Q), 
which is greater for Group A, doubtless owing largely to the greater width of skull; 
and to the angle formed by the inclination to the horizontal of the line joining 
alveolar point to basion {6.2) : this is significantly greater in Group A, while the dis- 
tance between these two points is about the same in the two groups. 
8. Comparison op Type Contours. 
We can now turn to the type contours and see what further points of difference 
or affinity are shown there to exist among our three types. 
The next three tables give the mean contour values from which type contours 
were constructed.
