Peter Collinfon, F. R. S. concerning a Water 
Infe<fl, which, being cut into feverai Pieces, 
becomes fo many perfect Animals.

covered a Water Infed, not known yet or defcribed 
by any Author. It has a pellucid Body, having here 
and there branched out fomething like Claws, with 
which it catches a particular fort of fmall Worms, 
which are every-whcre found in (landing Waters: 
Thefe are its Food. 
But of what Sort this Infe£t is, is not known ; nor 
have its Mouth, Stomach or Inteftines been yet dis- 
covered. 
But what is mod furprifing is, that, cut this Ani- 
mal in Five or Six Pieces, in a few Hours ^rere will 
be as many like their Parent.
