chelipeds showed a diminishing per cent, of gain when compared with 

 the corresponding normal appendage, i. e., in each successive re- 

 generation there was a larger per cent, of difference between the 

 lengths of the regenerated and the normal limbs. 



V. Regeneration and the moulting process. 



The following results were obtained from the observations on the 

 relation between the regenerative and the moulting process: 



1. A regenerating limb always moults as a junctional appejidage. 



2. There is a definite limit preceding a moult within which a limb 

 will not begin to regenerate. 



3. There is an adaptation of both regenerative and moulting pro- 

 cesses to the regenerating limb, favorable to the development of a 

 functional appendage at the first moult after injury.
