Between ten and twelve arid a half days regeneration is slow, reach- 

 ing its end for the two shortest removals at the latter day. The regen- 

 erated lengths at twelve and a half days are 0.9, 1.2, 1.8, 2.6, 4.7 and

5.8 mm. as shown in Tahle 42 and Figure 28. There is a steady increase 

 with increase in removed length. The specific lengths are 0.61, 0.46, 

 0.39, 0.31, 0.36 and 0.35 as shown in Table 42 and Figure 29. There is 

 an approach to constancy in the four largest removals.
