subsisted eighty-six days exuviation fulluwcd once more, on the i!3d of 

 Juno. 



What was now disclosed ? A new animal, considerably larger than 

 the oM, of the purest and most delicate white, with the whole limbs en- 

 tin.', svminetri( al, aii'l in beautiful perfection. 



1 on the -I could not liciiolil it without renewed ad- 



miration of Nat! s in producing her appointed works, in all 



tht-ir predetermined harmonious perfection. Plato XXXIX., fig. 8. 



This exuviation plainly proved, in confirmation of other example*, 

 that no [ inonncinx the ireneration of defective organs issues 



from the -tumps of the shell remaining on mutilation. Therefore re- 

 generations arc not by means of additions. 



tin-re are some perplexing facts. If each of the new limbs be 

 not withdrawn from a sheath, as from an old limb, according to com- 

 mon belief, how are the whole arranged with the body in the subsisting 

 shell exuviation ? Can it be otherwise than folding over the 



breast ? In my opinion it cannot. Certainly no portion of the originat- 

 ing organ protrudes from the stump of the delect ive memlier. Besides, 

 how could the bulging shell of the new claws be drawn through the nar- 

 row channels, and contracted joints of the old ? On the whole, therefore, 

 there seems no other satisfactory explanation than by admitting the 

 concent nit ion of the new animal and its organs within the original 

 shell. 



But how or from whence are the new integuments derived ; how are 

 they i::i ; j oscd so as to include the flesh of the limbs, or to contain the 

 internal parts ? I believe that skin is allowed to be derived from fleshy 

 parts, and although the bulk of the stomach is such that it might afford 

 some leaser secretion to invest the internal organization, the substance of 

 the limbs seems to have wasted almost entirely away. Content with 

 relating obvious facts, I must leave the solution of such abstruse 

 questions to greater physiologists. 



Whatever is the mode by which it is operated, if we admit that the 

 external parts of the creature nascitums, that about to be produced, are 

 generated, we are relieved of all embarrassment in accounting for the re-
