one of the Points of a very fmall Pair of ftiarp 
ScilTars into the Mouth of a ‘Polypus , and forcing it 
out at the very End of the Tail, he then laid it quite 
open like a Pigeon , or a Barbacute Pig to be 
broiled 5 yet, in about Five Hours, I faw the fame 
Polypus with the Parts fo reunited again, that I 
could not perceive any thing had been done to it; 
and it then eat a large Worm bigger than itfelf. He 
then fhewed me another odd Particular, which was 
one Polypus that had fairly Two Heads without any 
Tail ; that is, with a Head at each End, as you will fee in 
the Firft Figure annexed (fee p. 513*)* This was atl 
accidental Production, and the Manner it came about 
was as follows : Two young ones grew, as from one 
Root, out of an old Polypus , as in the Second 
Figure: They both dropt off together, and their Tails 
not being feparated, they appeared as in the Firft 
Figure; but, when I faw them, more like the Third, 
with feveral young ones putting out from their Sides. 
Mr. Trembley told me, he had feen the like fome- 
times before, but not often ; and that they have then 
remained Ten or Twelve Days in that Condition, 
after which they have feparated. You may lately 
have had this from Mr. Trembley himfelf; but, as 
it was moftly new to me, I would not omit com- 
municating it to you. He had in one of his large 
Glalfes upwards of a Hundred of thefe InfeCls all full- 
grown, and he regaled them all at once before me, 
with fome Thoufands of what he calls des Pucerons 
d’Eaity which are fmall aquatic Animalcule s t not 
unlike Fleas, of about the Size of large ones, and 
which move about with great Swiftncfs in the Water.
