The correlations are here less for the left than for the right-hand ring-finger 
bones. The law of neighbourhood is again broken for the distal phalanges of 
both right and left fingei-s, the metacai-pal bone in the first case and the proximal 
phalanx in the second being the most closely correlated bones.

Here the correlations have fallen again considerably, but the right hand is still 
more highly correlated than the left. The rule of neighbourhood is again broken 
in the case of the distal phalanges, which for both right and left little fingers are 
most closely correlated with the corresponding proximal phalanges. 
To sum up our results for longitudinal relationship of the bones of the hand, 
we conclude that : 
(a) The right hand exhibits somewhat more correlation than the left. 
(b) The thumb, index and little finger, the " marginal digits," have less 
correlation than the middle and ring fingers, the " central digits." 
(c) The proximal phalanx exhibits more correlation with the other longi- 
tudinal bones than the other phalanges or the metacarpal bones. The distal 
phalanx exhibits least correlation, — the metacarpal bone and the middle phalanx 
having about equal correlation and standing in this respect between the proximal 
and distal phalanges.
