IS 90"7 in the males and 87 in the females. If the index is reversed — 

 that is to say, the maximum length of the cranium is taken as 100 — it 

 is 110-3 in the males and 101*4 in the females. 



(e) The Canon of Proportion of the vertical length of head (vertex to 

 chin) to the stature ( = 100) is in the males 12-63 per cent., and in the 

 females 13-42 per cent. 



13. Nasal Index. — The variations of this index are very similar in 

 both sexes, ranging from 45-6 to 75 in the males, and from 47'1 to 76-7 

 in the females. 



14. Face Index. — The index of the face -which the Committee have for 

 some years past adopted is obtained from the length of the face, measured 

 directly -with callipers from the root of the nose to the nnder-surface of 

 the chin (=100), and the maximum bizygomatic breadth of the face. This 

 index in the living may be made to correspond -with that of KoUmann on 

 the skull by taking the zygomatic breadth as 100. 



The corrected mean length of cubit in the males and females is 26-8 

 and 262 per cent, of their respective corrected mean stature. 

 16. Length of Hand. 



The canon of proportion of the length of the hand to the stature is 

 in the males 1124 per cent., and in the females 10*94 per cent. 



By subtracting the corrected mean length of hand from the corrected 

 mean length of the cubit, the mean length of the forearm is obtained. lu 

 the males it is 270-6 mm., and in the females 244-4 mm. ; the length of 

 the hand to the forearm in the former is 72, and in the latter 71"2." The 

 canon of proportion of the forearm to the stature is 15'6 per cent, in the 

 males, and in the females 15-3 per cent.
