which thcfe Infeds multiply. What is there faid of 
them, is true and exact. The more one fearches into 
the Manner how a ‘Polypus comes from the Body of 
its Parent, the more evidently is one perfuaded, that 
it is done by a true Vegetation. 
There is not on the Body of a Polypus any diftin-

I have fome of them, that have greatly multiplied 
tinder my Eyes, and of which I might almoft fay,

and when one dropt off, another came in its Place.

and with Attention, I never obferved any thing like 
Copulation.

Parent, which was alone in a Glafs; or I even parted 
them with Scifiars : Each of thefe young ones I 
put into perfed Solitude, I fed them every one 
feparately in a Glafs ; they all multiplied, not only 
them-
