No. 33. — 1886.] THE VEDDAS OF CEYLON. 401 



of 960 and the man's of 1,614 cub. cm., we have a difference 

 of 654. The different ways of measuring may possibly have 

 increased the difference a little, but not enough to be of any 

 importance. 



The length measures stand in a close, but nowise simple, 

 relation to the capacity. In regard to the horizontal ex- 

 tent from the reports of Mr. Davis, I calculate as the average 

 of three male skulls 19*9 English inches == 506 mm., the 

 average of eight female skulls 19 in. = 483 mm., and the 

 average of thirteen skulls altogether 19*2 in. =488 mm. 

 From the figures given by Mr. Flower accrues an average 

 from five male skulls of 485, of two female skulls of 454, and 

 of seven skulls altogether 476 mm. From my measurements 

 accrues for three skulls an average of 486 mm., a figure pretty 

 near to the others. From all the twenty-three skulls I 

 calculate an average of 484 mm. ; from Mr. Davis's skulls 

 and mine, sixteen altogether, an average of 487 mm. The 

 lowest measure (448) was found by Mr. Flower with the 

 nannocephalous girl, the highest (512) with a man ; so here 

 too we have a difference in the extremes of 64 mm. The 

 skulls I have described prove here also absolutely typical. 



The measurement of the vertical line (right across the head) 

 admits of no exact comparison, since my measure extends 

 from one auditory passage to the other, that of Mr. Davis 

 from the base of one mastoid process to the base of the other. 

 Mr. Flower has not given any vertical lengths whatever. 

 According to my measurements the vertical extent is com- 

 paratively small, on the average only 289 mm., which is 197 

 mm. less than the horizontal extent, of which it is only 5*94 

 per cent. This figure shows most clearly the narrowness of 

 the skull. 



It is very difficult to measure the upper vertical extent 

 (sagittal from the root of the nose across the parietal bone to 

 the foramen occipitale) which differs, according to our two 

 statements, in the whole as well as in the single parts. It 

 amounts on the average : —
