riments concerning Fire.
WE deſigned to try whether or no
divers Magnetical Experiments
would exhibit any unuſual Phænomena,
being made in our Evacuated Receiver
inſtead of the open Air: But for want of
leiſure and conveniency to proſecute ſuch
Tryals, we were induced to reſerve the
reſt for an other time, and to content our
ſelves with making that which follows.
We convey'd into the Receiver a little
Pedeſtal of Wood, in the midſt of which
was perpendicularly erected a ſlender
Iron, upon whoſe ſharp point an excited
Needle of Steel purpoſely made, and of
about five Inches long, was ſo placed
that hanging in an Æquilibrium it could
move freely towards either hand. Then
the Air being after the uſual manner
pumped out, we apply'd a Load-ſtone
moderately vigorous to the out-ſide of
of the Glaſs, and found that it Attracted
or Repell'd the ends of the Needle, accor
ding to the Laws Magnetical, without
any remarkable difference from what the
ſame Load-ſtone would have done had
