once, he firft cut one into four Quarters, and let them grow ; 
then divided each Quarter, and proceeded fubdividing till he 
obtained fifty out of one : and has ftill by him feveral Pieces 
of the fame Polype thus cut above a Year ago, which have 
produced Numbers of young ones. 
If a Polype be cut the long Way, through the Head, Sto¬ 
mach, and Body, eacjh Part is half a Pipe, with half a Head, 
half a Mouth, and fome of the Arms at one of its Ends. The 
Edges of thefe halfPipes gradually round themfelves, and 
unite, beginning at the Tail-End ; and the half Mouth and 
half Stomach of each becomes compleat. All thi3 he has 
feen done in lefs than an Hour ; and the two Polypes thus 
formed differed nothing from whole ones, but in having 
fewer Arms ; which Defeft a few Days fupplied. A Polype has 
been cut lengthways between Seven and Eight in the Morn¬ 
ing, and between Two and Three in the Afternoon each Part 
has devoured a Worm as long-as itfelf. 
Cutting a Polype lengthways, through the Head and Body, 
but not quite through the Tail, in a fh,ort Time there will be 
two perfect Heads and Bodies with but one Tail: which Heads 
and Bodies may, foon after, be again divided in like Manner: 
and thus, Mr. Trem?l ey fays, he has produced a Polype with 
feven Heads and Bodies conjoined with but one Tail, Thefe 
feven Heads being cut off at once, feven others grew in their 
ffead : and each of the feyen Heads fo cut off, putting forth 
a new Body, became a compleat Polype. 
Pie cut a Polype tranfverfely afunder, and putting the two 
Parts clofe together, they united where they had been cut. 
The Creature eat the next Day, is grown - fince, and has mul¬ 
tiplied. The Fore-Part of one Polype united in the fame 
Manner to the Hind-Part of another. This compound Ani¬ 
mal eat likewife the next Day, and has fince produced young 
ones from each of the Parts that formed, it. But thefe two 
Experiments do not always fucceed, 
It was faid before, that the Body pf a Polype is a Sort of 
hollow Gut or Tube : this he has found means to turn infi.de 
out, as one may turn a Stocking; and has feveral at prefent 
by him, whole Infides remain to be their Qutfiaes; notwiths¬ 
tanding which, they eat, grow, and multiply, as if nothing 
had been done to them. He has repeated all thgfe Experi¬ 
ments feveral Times with the utmoft Precaution, Affiduity, 
and Attention; and might appeal, he fays, to the Quality 
and Number of the Perfons who have feen them made by 
him, as well as of thofe who have made the fame themfelves.
