fprout out 24 Hours after the Operation, and the new 
Head perfected in every refped in a few Days. 
Each of thofe Parts, thus become a perfect Poly- 
pus, performs absolutely all its Fundions. It creeps, 
it eats, it grows, and it multiplies 5 and all that, as 
much as a 'Polypus which never had been cut. 
In whatever Place the Body of a Polypus is cut, 
whether in the Middle, or more 'or lefs near the 
Head, or the pofterior Part, the Experiment has al- 
ways the fame Succefs. 
If a Polypus is cut tranfverfly, at the fame Mo- 
ment, into three or four Parts, they all equally become 
fo many complete ones. 
The Animal is too fmall to be cut at the fame time 
into a great Number of Parts 5 I therefore did it fuc- 
ceflively. I firft cut a Polypus into four Parts, and let 
them grow; next, I cut thofe Quarters again ; and at 
this rate I proceeded, till I had made yo out of one

I have now ad u ally by me feveral Parts of the fame 
Polypus , cut into Pieces above a Year ago; fince

young ones. 
A Polypus may alfo be cut in two, lengthways. 
Beginning by the Head, one firft fplits the faidHead, 
and afterwards the Stomach : The Polypus being in 
the Form of a Pipe, each Half of what is thus cut

of which is terminated by the half of the Head, the 
half of the Mouth, and Part of the Arms. It is not 
long before the two Edges of thofe Half-pipes clofe, 
after the Operation : They generally begin at the
