a comparison of completeness of regeneration but for such a comparison 

 it is better in some ways to compare the regenerations at the time when 

 absorption lias not begun. The greatest average regenerated length 

 attained for the 1.5 mm. level is 0.9 mm. at ten days, for the 2.6 level 

 1.2 at twelve and a half days, for the 4.6 level 1.8 at twelve and a half 

 days, for the 8.2 level 2.7 at eighteen days, for the 13.0 level 5.5 at 

 eighteen days and for the 16.7 level 6.9 at fifty-six days. There is an ■ 

 uninterrupted increase from the shortest to the longest removal in com- 

 plete amount regenerated. This is shown graphically in Figure 34. The
