would not fear to
affirm, that it is no obscure sensation this Plant hath. But I have
said too much, I humbly submit, and am ready to stand corrected.

I have not yet made so full and satisfactory Observations as I desire on
this Plant, which seems to be a Subject that will afford abundance of
information. But as farr as I have had opportunity to examine it, I have
discovered with my _Microscope_ very curious structures and contrivances;
but designing much more accurate examinations and trials, both with my
_Microscope_, and otherwise, as soon as the season will permit, I shall not
till then add any thing of what I have already taken notice of; but as farr
as I have yet observ'd, I judge the motion of it to proceed from causes
very differing from those by which Gut-strings, or Lute-strings, the beard
of a wilde _Oat_, or the beard of the Seeds of _Geranium_, _Mosscatum_, or
_Musk-grass_ and other kinds of _Cranes-bill_, move themselves. Of which I
shall add more in the subsequent Observations on those bodies.

Observ. XIX. _Of a _Plant_ growing in the blighted or yellow specks of
_Damask-rose-leaves_, _Bramble-leaves_, and some other kind of leaves._

I have for several years together, in the Moneths of _June_, _July_,
_August_, and _September_ (when any of the green leaves of _Roses_ begin to
dry and grow yellow) observ'd many of them, especially the leaves of the
old shrubs of _Damask Roses_, all bespecked with yellow stains; and the
undersides just against them, to have little yellow hillocks of a gummous
substance, and several of them to have small black spots in the midst of
those yellow ones, which, to the naked eye, appear'd no bigger then the
point of a Pin, or the smallest black spot or tittle of Ink one is able to
make with a very sharp pointed Pen.

Examining these with a _Microscope,_ I was able plainly to distinguish, up
and down the surface, several small yellow knobs, of a kind of yellowish
red gummy substance, out of which I perceiv'd there sprung multitudes of
little cases or black bodies like Seed-cods, and those of them that were
quite without the hillock of Gumm, disclos'd themselves to grow out of it
with a small Straw-colour'd and transparent stem, the which seed and stem
appear'd very like those of common Moss (which I elsewhere describe) but
that they were abundantly less, many hundreds of them being not able to
equalize one single seed Cod o
