in the Coals began to grow very dim, and
though the agitation of the Vessel did
make them swing up and down (which in
the free Air would have retarded the ex­
tinction of the Fire) yet when we could
no longer discern any redness at all in any
of them; casting our eyes upon a Minute­
Watch we kept by us on this occasion, we
found that from the beginning of the
Pumping (which might be about two mi­
nutes after the Coals had been put in
glowing) to the total dis-appearing of
the Fire, there had passed but three mi­
nutes.

Whereupon, to try the Experiment a
little further, we presently took out the
Coals, in which it seems there had re­
mained some little parcels of Fire, rather
cover'd then totally quench'd: For in the
open Air the Coals began to be re-kind­
led in several places, wherefore having by
swinging them about in the Wier,
throughly lighted them the second time,
welet them down again into the Receiver,
