The general average index of 107.3 makes the series platy- 

 opic, whichever method is used, since the maximum limit 

 placed by Thomas for platyopism is 107.4 an< 3 Risley's maxi- 

 mum limit is 109.9. 



Thomas gives an interesting comparative table of average 

 naso-malar indices, to which that of the series under discus- 

 sion is added: 



Dental index 1 . On the whole, extreme indices seem to 

 characterize the male sex in any given race. That is to say, 

 indices which commonly fall below 100 average higher, and 

 those greater than 100 average lower in the female sex than in 

 the male. In the Neu Pommern series,.. for instance, the eleven 

 indices smaller than 100, average 77.7 for the males, and 78.3 

 for the females; while the three indices greater than 100,
