containing ten or twelve times as much.

Our scope in this Experiment was
partly to try whether or no the smoke of
the Match, replenishing the Receiver,
would be able to hinder the Dilatation of
the inward Air, upon the exsuction of the
Ambient. And partly to discover whe­
ther the extinction of the Fire in the
Match did proceed from want of Air, or
barely from the pressure of its own
Fumes, which for want of room to ex­
pand themselves in, might be suppos'd
to Recoyl upon the Fire, and so to
stifle it.

The event of our tryal was, That
at the beginning of our Pumping the
Match appear'd well lighted, though
it had almost fill'd the Receiver with
its plentiful Fumes: But by degrees it
burnt more and more dimly, notwith­
standing that by the nimble drawing
