And first, for the extent horizontally I have, in like 

 manner, as with the Veddas, after putting the figures of 

 Mr. Davis into metre measure (leaving out here also the 

 skull No. 980), received as an average of — 



Compared with the Vedda skulls of Mr. Davis, the diffe- 

 rence in favour of the Sinhalese amounts to 26*11 and 23 mm. 

 My two Sinhalese skulls, whose small capacity is clear from 

 the previously given numbers, show only 482 and 493 mm. 

 extent horizontally : consequently, in the one case it is 

 somewhat less and in the other somewhat more than the 

 average of the Colombo skulls which I measured. On the 

 other hand, the size vertically (398 and 293 mm.) proved 

 greater with my Sinhalese than the average of the Colombo 

 skulls (298 mm.). One of the latter, however (No. 5), has a 

 higher measure (300 mm.). In the average, the vertical 

 compass of my two Sinhalese skulls is 192 mm. less than the 

 horizontal, of which it is 60'5 per cent. ; therefore somewhat 

 more than with the Veddas. 



I have likewise calculated the length of circumference of 

 Mr. Davis's skulls, taken with the sagittal suture. I receive 

 an average from — 



4 Male skulls ... ... 393 mm. 



5 Female skulls ... ... 370 mm. 



9 Sinhalese skulls ... ... 380 mm. 



whilst my own measurements amount to 354 and 365 mm. 

 The corresponding average with the Vedda skulls amounts 

 to 366 (Davis) and 355 (Yirchow) mm. 



As regards the single segments of the sagittal arch, I find 

 the following average from Mr. Davis's figures : —
