Although determination of sex was arrived at in our presence, often aided by 

 the possession of other bones from the same skeleton for comparison, it has been 

 thought best in this case to apply to the tibiae the method used by Dr. Manouvrier 

 in his exhaustive paper on platycnemia, which paper is referred to at length in our 

 account of the Tick Island mound. 



The learned Doctor takes the sum of the lateral and antero-pusterior diameters 

 of each tibia? and arranges the sums thus obtained in sequence from the greatest to 

 the least. This list he divides into three equal parts, considering the first third as 

 males ; the second third as uncertain, though mainly undersized men ; while the 

 bones of females are presumed to be included in the last portion of the list, The 

 preponderance of males over females he attributes to the greater fragility of feminine 

 bones. 



Forty-four tibia? from Mulberry Mound give the following results by this method :

The average of the 44 tibiae, irrespective of sex, gives an index of 66 - 8.
