and an half and two lines, but when view’d with a 
good microfcope, whofe focus is about eight lines, it 
appears as you fee in Plate VII. i, with leaves, 
branches, and fruit, and indued with fuch fenlibility, 
that at the lead noife made in the room, or upon any 
thing’s touching the table w^here your microfcope 
Hands, or the water in which it lies, it contrads it- 
felf with fuch adivity and fwiftnefs, that the eye 
cannot follow it in that motion, till it reduces itfelf 
into the fhape you fee it twifted in Fig. 2. The ex- 
tenfion or dilation goes flower, and requires about 
half a minute before it comes to the form you fee it 
in, like a grape, in Fig. 5. It can live in its own 
Handing- water for eight or ten days, and then looks 
as you fee it in Fig. 6 . as moH trees do in winter- 
time. It is remarkable, that the leaves, which are 
like bells, live fome time after they fall, and retain 
that faculty of contradion and dilatation j and 
when you view them with our great magnifier, 
whofe focus is about two lines, it appears as in Fig. 4. 
The trunk is as you fee it in Fig. 3. The number 
of its branches are undetermin’d, but commonly 
found to be betwixt flx and twelve. We have not 
tried, if it does not regenerate, when cut, like po- 
lypes : But one can fee a vaH difference betwixt it 
and the Polype a bouquet., of which Mr. Trembley 
makes mention. The other curious infed reprefented 
in Fig. I. is found in the fame Handing-waters 
with the plant, and is feen with the naked eye, like 
a little flat round leaf, whofe diameter is about one 
line and an half j but when put in a mifcrofcope, it 
fliews a circle furrounded with crown’d heads, tied 
by fmall thin tails to a common centre; from whence
