In all the other muscles of the right and left forearm, there 

 was a slight preponderance of the muscles of the left (unin- 

 jured) side over those of the right side, but it was not so 

 marked in any as in the deep flexors of the fingers, and in 

 the long palmar muscle, which were directly involved in the 

 injury occasioned by the overgrowth of the claws. The abso- 

 lute and relative weights of the muscles of the two forearms 

 are shown in the following table : —
