6. Length of Leg, including Height of Foot. — This is obtained by sub- 

 tracting the height when kneeling from the total stature : — 



7. Proportion tvhich the Limbs bear to the Trunk. — This is obtained by- 

 reducing the length of the trunk of the body (including the head and neck) 

 and the length of the limbs to percentage terms, the former being taken as 

 100. Each body and limb length is -worked out by the following formula : 



Limb length x 100 

 Body length 



which gives the Limb to Trunk Index. The several indices are then treated 

 in the same manner as other measurements and indices, so as to show the 



The proportion which the limbs bear to the trunk in males of 1,828 mm. 

 (6 feet) and upwards, of whom there are seven, at the 50th grade of this 

 small series is 89-5, or exactly the same as at the 50th grade of the whole 

 series of males. This series may be termed the tall class. In a series of 

 six males whose stature is 1,613 mm. and under (5 feet 3^ inches), it is 

 at the 50th grade 86-5, which is practically the same as at the 25th grade 

 of the whole series. Hence the lower limbs in the series of short men are 

 proportionately somewhat shorter to the body length than in the tall 

 series ; but it cannot be said that in the latter series it is on account of the 

 lower limbs being longer proportionately to the trunk length that the tall 

 persons of the group owe their extra stature to. Both series are too small, 

 however, to base any reliable conclusions upon. 



8. Projwrtiojis tvhich the Trunk and Loicer Limbs bear to the Stature. — 

 The proportions contributed by the different parts of the body which go 

 to make up its total stature are as follows : — 



IMalea. Females. 



(a.) Trunk with the head and neck , , 52-3 per cent. 53-0 per cent.

 males and 47 per cent, in the females, is made up as follows : —
