As far as these results go it appears that the maximum regener- 

 ating limit obtained was ten days and that the maximum non-re- 

 generating internal was four days; or, in other words, the chelipeds 

 of the sixth stage lobster will regenerate if removed ten days before 

 the following moult, and that the same limbs will not regenerate if 

 removed (two days in the case of the sixth stage or four days in the 

 case of the seventh stage) before the next moult. No data has yet 

 been secured to show whether a limb would or would not be restored 

 if removed between four and ten days preceding a moult? In the 

 more mature lobsters the shortest period noted in which a thoracic 

 appendage began to regenerate was sixteen days.
