Between the eighth and the tenth day there is a rapid decrease in 

 rate associated with tissue differentiation. The regenerated lengths at 

 ten days are 0.9, 1.0, 1.7, 2.3, 3.8 and 4.5 mm. as shown in Table 41 

 and Figure 26. There is an uninterrupted increase in regeneration with 

 increase in removed length. The specific lengths are 0.58, 0.38, 0.37, 

 0.28, 0.29 and 0.27 as shown in Table 41 and Figure 27.
