© We had alfo an Opportunity of feeing thofe Corallines in 
Motion, whofe Polypes.are contained in Cups, fapported by 
a long Stem that appears full of Rings, -or as if they were 
twifted in Form of a Screw (See Fig. C) Plate XU). In

As we were obferving this, we accidentally difcovered the 
Figure of the Polype, that fpreads its Cells over Fucus’s, and 
other Marine Subftances. ‘The Figures of the Cells are ex~

On feveral Parts of thefe Corallines there are little Bodies, 
which, through the Microfcope, appear to be fo many Ve- 
ficles or Bladders:, To the Ufe of thefe I was altogether a 
Stranger till this Journey: But now I difcovered that they 
were Matrices, or Habitations of young Polypes, which are 
produced here and there, on the Sides of the Parent, as in 
the Frefh-water Polype, only in :the marine ones: they are 
protected with this veficular Covering. ‘T hefe: Veficles' ap- 
pearing ata certain Seafon of the Year, according to the

Bloffoms or Seeds of Plants, has made fome curious Perfons, | 
who have not had an Opportunity of feeing the Animals alive 
in the Veficles, conclude them to be the Seed-veffels of Plants; 
and into this Miftake I was led my‘felf, in the Account laid 
before the Royal Society in 1752. In which Account I had 
_ taken fome Pains to point out the ereat Similitude between 
the Veficles, and denticulated Appearance of fome of thefe

of fome Species of Land-mofles, particularly of the Hypzum
