Now looking at the column headed " mean " we see that for the metacarpal 
bones, the proximal phalanges and the middle phalanges the right hand is larger 
than the left. And in the same manner the total thumb (D,) and finger lengths 
of bone {D^, D-^, D^, D^) are larger on the right than the left. If we take the 
distal phalanges, then it would appear that the left was larger for all the fingers 
and the right for the thumb only. But if we take the 37 cases in which we 
have bones from both hands of the same individual, the means work out :
