LIMB MEASUREMENTS. 107 



Eleven of these lie between 67 and 68: and since the average of my numbers, 

 which is 68, corresponds with the value of the median of the series, we will 

 take this index of 60 as representing the average ratio of the lengths of 

 the two limbs compared together.

(2) The index of the fore-arm and arm, or the ratio between the lengths 

 of the fore-arm and arm, taking the latter as 100. The range of 27 

 indices is 79 to 100. Of these 16 are included between 87 and 91; and 

 the average of the numbers is 88.

(3) The index of the leg and thigh, or the ratio between the lengths of 

 the leg and thigh, taking the latter as 100. The range of 27 indices, as 

 shown in the subjoined table, is 68 to 97. Of these, two-thirds are in- 

 cluded between 74 and 83 : and since the value of the median, which is 80, 

 corresponds nearly with the average of the numbers, we may take it as 

 representing the average proportion which the leg bears to the thigh amongst 

 these natives.
