from that of the Veddas and the Sinhalese, though somewhat 

 smaller than with the latter. The hybrid, No. 316, of Mr. 

 Davis has only 475, not much more than the Sinhalese (?) 

 child, 472 mm. 



The vertical circumference, on the other hand, constantly 

 rises above that of the Veddas as well as the Sinhalese. It 

 amounts in my three skulls, in the average, to 306 mm., 

 against 289 with the Veddas and 295 with the Sinhalese. 

 This average is only 174 mm. smaller than that of the 

 horizontal circumference of the corresponding skulls (480 

 mm.), which is 63*7 per cent., against 59*4 with the Veddas 

 and 60*5 with the Sinhalese. This difference is very 

 noteworthy. It is found also with the child (Sinhalese 

 No. 3). 



The circumference of the skull from Mr. Davis's col- 

 lection, taken through the sagittal suture, measures 353 mm. ; 

 that of mine 359, 351, and 352 ; therefore, in the average, 

 353 mm., against 376 with the Sinhalese and 363 with 

 the Veddas. Plainly the question here, however, is as to the 

 complementary relation to the vertical measure, for the 

 sagittal circumference in length amounts in the case 

 of the —

of the horizontal circumference. 



In an investigation as to the share of the individual por- 

 tions of the roof of the skull to its whole circumference 

 (scheitelbogen), the striking anomaly is directly presented 

 of the plagiocephalic skull (No. 1 in my collection), which 

 is remarkable for the great development of the middle and 

 back parts of the skull-roof, owing to which there is a 

 perfectly abnormal shortening of the frontal portion. 

 This will be best understood by a comparison of the 

 figures.
