4 Male skulls ... 



34-6

5 Female skulls...

9 Sinhalese skulls

30-2 



Here, as contrasted with the Veddas, we notice in a very 

 striking way the important part taken by the frontal and 

 parietal bones, especially the first, and the insignificant part, 

 on the contrary, assigned to the occipital bone. 



With my two skulls the proportions for the middle of head 

 appear most favourable, and therefore rather according to the 

 female type of Mr. Davis's skulls : — 



No. 1 ... 33-6 ... 35-3 ... 31-0 



No. 2 ... 33-9 ... 35-6 ... 30-4 



The proportion of the sagittal vertical extent to the hori- 

 zontal amounts in Mr. Davis's skulls to 74*3, in mine to 73*7 : 

 hence almost the same numbers as with the Veddas. 



As regards the form of the head, I have already given the 

 particulars of Mr. Davis's skulls. The ratio of the average 

 of length and breadth is, according to index, the following : — 



Skulls. 



Dusseau ... ... 1 ... 72-2 



Davis ... ... 9 ... 72 



Virchow ... ... 2 ... 707 



On the whole, from ... 12 ... 71*8 



This excellent dolichocephalous measure accords almost 

 exactly with the Vedda average (71*6). Even if we take into 

 consideration the five skulls measured by Mr. Welcker, and 

 omit the ,one mentioned by Mr. Dusseau, the average for 

 sixteen skulls only amounts to 72*2. I will not lay any 

 particular stress upon the difference in sex, since even with 

 the Veddas contradictory numbers have been shown. I can 

 only say authoritatively that Mr. Davis's figures for the female 

 Sinhalese heads show a smaller proportion (71*2) than those 

 of the men (73). But here I must say that the previously 

 described skull (No. 982), which Mr. Davis, for spme reason
