pofterior Part, and clofe up by degrees to the ante-' 
, rior Part. Then, each Half-pipe becomes a Whole- 
one, complete : A Stomach is formed, in which no- 
thing is wanting ; and out of each Half-mouth a 
Whole-one is formed alfo. 
I have feen all this done in lefs than an Hour; and 
that the Polypus , produced from each of thofe Halves, 
at the End of that time did not differ from the Whole- 
ones, except that it had fewer Arms; but in a few 
Days more grew out. 
I have cut a Polypus , lengthways, between Seven 
and Eight in the Morning; and between Two and 
Three in the Afternoon, each of the Parts has been 
able to eat a Worm as long as itfelf. 
If a Polypus is cut lengthways, beginning at the 
Head, and the Section is not carried quite through; the 
Refult is, a Polypus with two Bodies, two Heads, and 
one Tail. Some of thofe Bodies and Heads may again 
be cut, lengthways, foon after. In this manner I have 
produced a Polypus that had feven Bodies, as many 
Heads, and one Tail. I afterwards, at once, cut off 
the feven Heads of this new Hydra: Seven others 
grew again ; and the Heads, that were cut off, became 
each a complete Polypus. 
I cut a Polypus , tranfverfly, into two Parts : I put 
thefe two Parts clofe to each other again, and they re- 
united where they had been cut. The Polypus , thus 
reunited, eat the Day after it had undergone this O- 
peration: It is fince grown, and has multiplied. 
I took the pofterior Part of one Polypus , and the an- 
terior of another, and I have brought them to reunite 
in the fame manner as the foregoing: Next Day, the 
Polypus that refulted, eat : It has continued well thefe
