solid body with respect regard to a fluid one; as a
cork for instance, or other stopple with regard to the
water in a bottle. The portion of a fluid that
is made to answer the purpose I would therefore
call a Stopple. When the fluid made
use of is Water, a Water Stopple.

Mercury Stopple

Some Mercury vapours however meantime , as Fixable Air, and
the Muriatic Acid were found to be act upon
the stoppel a water and be taken up by the stopple
when composed of water. Water therefore could
not serve to confirm them in the state it was
meant to keep have them in. Mercury Quicksilver was then
thought of as a substitute. This, Sir, I presume,
was your invention. When Mercury Quicksilver
is thus employ'd , I would therefore call it a
Mercury Quicksilver-Stopple; when Oil, an Oil -
Stopple, and so on.

Stopple-cap

The fluid used as a stopple must have a
solid vessel to contain it: This Vessel is
either the general reservoir and of in and from which the
Receivers are filled, or a small one in which
the Air with it's stopple is set by apart from
the rest. I would call it a Stopple-Cap. [+] [+] if the term be not too uncouth in
the first case the general stopple-cap: in the second
a particular one.
