many of which are often fo united, as to form 
together a Sort of Branches, or Clufters ; and this 
Sort of Appearance determined Monfieur P)e Reau- 
mur to name the Animalcula that appeared fo fixed, 
clujlering Polypi : des Polypes en bouquet. 
Thele Cinders are larger or Idler, according to the 
Species of the Polypi that form them, and according 
to the Concurrence of many other Circumftances. 
To get a clear Idea of the Figure of thefe Animals, 
it is bed to obferve the fmaller Clufters 5 as, in the 
larger, the great Number of the Polypi upon the 
feveral Stems, are apt to hide one another. 
There is a Cafe, I fhail mention prefenrly, where 
the Polypi are finglc j and it is proper to obferve them 
in that Cafe j and the rather, becaufe that is the Way 
to difeover how the Clufters are formed. 
I fhail now deferibe one of thefe ftngle Polypi , to 
give a general Idea of the Form of the Animal : and 
1 fhail herein chiefly endeavour the Defeription of 
that Species which I have moft particularly made my 
Obfervations upon. 
Thefe are not in Length above the 240 th Part of 
an Inch, and are of a Shape nearly refembling that 
of a Bell : this may be feen in the Figure, where one 
of them is reprefented exceedingly magnified (Tab. II. 
Fig. 5.). The anterior Part, ac, generally appears 
open, when it properly prefents itfelf; the pofte- 
rior Part b is fixed to a Stem or Pedicle be\ and it 
is by the Extremity e of this Pedicle, that rhe Polypus 
fattens itfelf to any other Sort of Body. The Polypus 
of this Sort generally appears to the Microfcopc of a 
brownifh Colour, excepting at its fmaller End b, 
where it is tranfparenr, as well as its Pedicle be. 
When the anterior Part a c is open, one may per-
