one. I have earlier expressed my idea* about a form which 

 is determined by two wholly different factors, not necessarily 

 united to one another, viz., the height of the nose and 

 the breadth of the aperture. But it is not worth while to 

 continue this discussion at present, with so little material. 



Only six of Mr. B. Davis's skulls offer material for deter- 

 mining the index of the face, and of these five are female. 

 I have computed them as follows : —

Here a very considerable contrast appears to the Yeddas. 

 Whilst the highest measure of the male Yedda was 88*2, with 

 the Sinhalese we have a male skull of 98'4 and two female 

 skulls of 92*1 and 95*6 ; a third female skull has an index of 

 88*8. There remain only two female skulls with low 

 measures, one 81*6 and one of a weak-minded person, which 

 is 77*7. Whilst the total average with the Veddas was only 

 something over 83, I find for the Sinhalese 89. 



If we now reflect that of the female skulls, as a rule, the 

 measure is lower, and that here, of six skulls, five are female, 

 among which is included the abnormally low measurement 

 of the skull of a weak-minded person, we may assume as 

 very probable that the Sinhalese face index in the classifica- 

 tion suggested by Mr. Pvollmann (which, however is based 

 upon a somewhat different computation) is leptoprosopic. 

 The smallness of the yugal distance is decidedly in favour of 

 such an assumption.
