a large proportion of the total mass of the regenerated organ. Since 

 apparently the length of this mass of cells is very much alike at all 

 levels as indicated by the facts of the four day regenerations, the specific 

 lengths for these short removals are greater than for the others. The 

 high values of the two longest removals are due to a continuation of
