622 BEPORT — 1892. 



the corrected mean is 161"5. The index of the relative proportion which 

 the length of the head from the glabella to the occiput bears to the length 

 from the vertex to the chin (the latter being taken as 100) is 93 ; that 

 of the breadth to the vertical projection of the head is 72'9 in the males. 

 If the glabello-occipital length is taken as 100, the index it forms 

 with the total projection of the head is 107'5. 



Nasal Index. — In the males the nasal index is 56'5 at the 25th 

 grade ; at the 50th, 60-3 ; at the 75th, 64-8 : ' Q ' is 4-1, and the cor- 

 rected mean 606. In the females it is at the 25th grade 55"! ; at the 

 50th, 55-9 ; at the 75th, 56'6 ; ' Q ' is "7, and the corrected mean is there- 

 fore 55'8. The index ranges in the males from 48'2 to 86"6, and from 

 49 to 66"6 in the females. 



Face Index. — In the males the facial index is at the 25th grade 105 ; 

 at the 50th, 110 ; at the 75th, 119 ; ' Q ' equals 7, and the corrected mean 

 112. In the females it is at the 25th grade 106; at the 50th, 114; 

 at the 75th, 118 ; ' Q ' equals 6, and the corrected mean 112. This index 

 is calculated from the bizygomatic breadth and nasio-mental length of 

 the face, the latter being taken as 100. 



Length of Cubit. — In the males the length of cubit at the 25fch grade 

 is 452; at the 50th, 4647 ; at the 75th, 478 ; 'Q' equals 13, and the 

 corrected mean is 465. The corrected mean length of cubit is 26'8 per 

 cent, of the corrected mean stature. In the females the length of the 

 cubit at the 25th grade is 404 ; at the 50th, 419 ; at the 75th, 431 ; ' Q ' 

 equals 14, and the corrected mean is 417. The cubit in them is 25"9 of 

 the stature. 



Lengtlt of Hand (right). — In the males the length of the right hand at 

 the 25th grade is 1866; at the 50th, 192-6; at the 75th, 199-6; 'Q' 

 equals 6-5, and the corrected mean 193. The corrected mean length of 

 hand is 11-1 per cent, of the corrected mean stature. In the females 

 the length of hand at the 25th grade is 170; at the 50th, 177-8 ; at the- 

 75th, 184-2 ; ' Q ' is 6-6, and the corrected mean 177-6, or 11-0 per cent, of 

 the corrected mean stature ; in the males the 41-5 per cent, of the cubit, 

 and in the females 42-5 per cent. Subtracting the corrected mean length 

 of the hand from the corresponding length of the cubit, the mean length 

 of the forearm proper is 272 in the males and 239 in the females ; the 

 length of the hand is to that of the forearm in the former as 71, and in 

 the latter as 74-3 to 100. 



Span of Arms. — In the males the span of the arms varies from 1,575 

 to 1,900 ; "at the 25th grade it is 1,738 ; at the 50th, 1,771 ; at the 

 75th, 1,814 ; ' Q ' is 38, and the corrected mean is 1,776. In the females 

 it is at the 25th grade 1,550; at the 50th, 1,601; at the 75th, 1,644; 

 ' Q ' equals 47, and the corrected mean is 1,597. The proportion which 

 the span bears to the stature (the latter being taken as 100) is in the 

 males as 102-6, and in the females 105-2. The span of the arms exceeds 

 the stature in 10 cases out of 70 in the males, and in 13 out of 26 in the 

 females, or in 14-3 per cent, of the former, and in 50 per cent, of the 

 latter. 



Weight. — In the males the weight at the 25th grade is 144 lbs. ; 

 at the 50th, 162-5 lbs. ; at the 75th, 167 lbs. ; 'Q' equals 11-6, and the 

 corrected mean is 156 lbs., or 11 st. 2 lbs. In the females it is at the 

 25th grade 116-7 lbs. ; at the 50th, 122-5 lbs. ; and at the 75th, 131-7 lbs. ; 

 ' Q ' equals 7-5, and the corrected mean is 124-2 lbs., or 8 st. 12 lbs., that 

 is, 2 st. 4 lbs. less than the males.
