not for the fact that the actual excess, not the percentage excess, of 

 nerve fibers is greater on the operated than on the intact side, being 

 242 nerve fibers for the operated leg and 204 nerve fibers for the 

 intact leg.

If we are correct in interpreting this excess as dne to the presence 

 of splitting nerve fibers, it becomes necessary to consider in what 

 way the presence of splitting fibers would modify the enumerations 



at the various levels of the two legs.
