Corresponding to the smallness of the skull, the greatest 

 length is throughout little : dolichocephaly is less indicated by 

 great length than by want of breadth. Among all the skulls 

 there is only one — a male skull (Davis, No. 805) — which has a 

 length of 190 mm. (76 English inches). With all the rest it is 

 less, with the majority not more than 180. The greatest 

 breadth, likewise, comes up in only one skull to 140 mm. ; the 

 next highest figure is 135 — the measure of the male skull from 

 the Colombo Museum. But the majority do not even reach 

 130. All the more extraordinary is the relatively considerable 

 height. Only twice do we find height less than the breadth. 

 The skull (No. 683, Mr. Flower's) which shows some other 

 aberrations as well, has a breadth of 140 mm. and a height of 

 only 135 mm.; and a male skull (Davis, No. 804) that shows 

 various synosteoses, and is clinacephalous, has a height (5 in.) 

 a little less than the breadth ; in all the other cases the 

 height exceeds the breadth, and not set down very con- 

 siderably — in one case (Flower's, No. 680) by 14 mm. The 

 greatest height (136 and 137 mm.) is that of two male skulls 

 —one of Mr. Flower's and one of mine. 



The index of ratio between the length and height is, there- 

 fore, greater than between the length and breadth. After 

 excluding the two deformed skulls, it amounts to an average 

 of
