We see again that the marginal fingers as a rule have least correlation. There 
are three insignificant deviations from the rule that a bone has always more corre- 
lation with a second of the same series than with any other bone from which it is 
separated by the second. There is one significant deviation, e.g. the correlations 
of the little finger middle phalanx with those of the index and middle fingers of 
the left hand. 
Lastly, turning to the distal phalanx we have the following Tables :

Here again the correlations have still further fallen ; there is no balance of 
correlation significantly in favour of either hand. The marginal digits are again the 
least correlated. There are further interesting and significant deviations from the 
rule as to the relationship of correlation to neighbourhood. The distal phalanx 
of the thumb in both hands is most highly correlated with the distal phalanx of 
the ring finger and the correlation drops in either direction from this. The little 
finger distal phalanx is more highly correlated in both hands with that of the 
index finger than with that of the closer middle finger. It would thus appear that 
special relations hold for the marginal digits at least in regard to the distal 
phalanges, if not also for the middle phalanges. 
We may add to these results for individual bones similar results for the 
whole bone length of the four fingers.
