12 HARG1TT. 



As to the processes involved in these phases of regeneration 

 my experiments confirm in the main those of both Hargitt and 

 Morgan. 



Hargitt, '97, says concerning it, "there seems to be an intrin- 

 sic potency to recast itself into the morphological equivalent of 

 the original." Morgan says the process " is one of rounding up of 

 the piece in direction of least resistance. The meeting of the 

 edges may sometimes be due to simple accidental meeting of the 

 bent-in portions." My own experiments showed no evidence of 

 a merely accidental or mechanical process, but rather self-direc- 

 tive activity inherent in each portion of the individual. The proc- 

 ess was in all cases gradual and orderly and the meeting of the 

 edges too exact and certain to be explained as the result of mere 



accident.
