In every case the right hand exhibits more spumous correlation than 

 the left, and our previous conclusion is thus thoroughly confirmed : 

 the left hand exhibits higher organic correlation of its parts than the 

 right. How is this to be explained ? It is all important that further 

 researches shoidd determine whether it is selection or use which 

 differentiates the two hands. It would be hardly possible to find a 

 sufficiently large group of left-handed persons to mark how far varia- 

 tion and correlation were modified ; but measurements on the hands 

 of children, of the educated and uneducated, and of workmen following 

 particular trades might possibly throw light on the extent to which use 

 modifies correlation. 



"We append the correlation tables giving the data upon which our 

 numerical values are based.
