Animalcules in Waters , 
Jie sods, tnat in the Hiftory of the Polype , which he has in 
Hand, all the Methods and Contrivances ufed by him in his 
Observations will bedefcribed ; but even before its Publican 
tion he is ready and willing to communicate any Infer-? 
mation that may enable others to perform the like. 
Mr. Re aumur, Fellow of the Royal Academy of Science? 
in France, declares (in the Preface to the fixth Volume of hi? 
MJlory of Infeaf juft publilhed at Paris) that he has repeated all 
Mr. Trembler’s Experiments, not only byhimfelf, but with 
Mr. Jussieu, and feveral others of the faid Academy, and 
found them fucceed as they had done in Holland, of which he 
gives a general and fuccind Account. When firft he favv two 
compleat Animals forming themfelves from the Parts of one 
Polype cut afunder, be knew not, he fays, how to believe hi? 
Eyes ; and he cannot yet behold it without new Amazement, 
though he has feen it an hundred and an hundred Times. He 
adds, that the Curious in France foon began to try if other 
Creatures might not be found with the lame extraordinary 
Faculty. That Mr. Bonnet foon difeovered a Bender Water- 
Worm about one Inch and half long, that had the fame 
Property ; and Mr, Lyonett found another about three 
Inches long, and the Thicknefs of the treble String of a 
Violin, which being cut into thirty or forty Barts affordecl 
the fame Phenomena. 
Mr. Reaumur, imagining that fome Sea Predu&ions, 
whole Shape fomewhat refembles this FreJb^Water Polypel 
fuch as the Urticf Marines and Star-Fijh , might have the 
like Faculties, engaged Mr. Guttarb and Mr. Jussieu 
to make Variety of Experiments on the Coafts of Poidlou and 
Normandy. They broke and cut Star-Fijb into feveral Parts, 
and had the Pleafure to fee the feveral Parts continue alive, 
arid their Wounds cicatrize and heal: and though they could 
not Bay long enough in the Country to fee new Parts Ihoot 
forth inftead of thofe cut away, Mr. Gerrard de, Vil«? 
Lars has feen the Urticce, on the Coafts near Rochelle, re-pro¬ 
duce all the Parts cut off, and the Star-Fijb putting forth 
new Radii inrthe Room of thofe they had been deprived of. 
When the Filherrnen faw Mr. Jussieu tearing and cutting 
one of thefe Animals in Pieces, they told him, it was Labour 
in vain, he could not kill it; Experience having taught then* 
what Men of Learning had never fo much as heard of. 
Mr. Reaumur and Mr. Bonnet found alfo fome Sorts of 
Earth-Worms, which being cut in two, each Half had all its 
Beftciencies re-produced after fome Months. Many, indeed.
