We likewiſe cauſ'd a piece of Steel to
be made of the form and bigneſs of the
Flint, in whoſe place we put it, and then
the Piſtol being cock'd and conveyed in
to the Receiver, the Trigger was pull'd
after the Air was drawn out: And though
the place were purpoſely ſomewhat dar
ken'd, yet there appear'd not upon the
ſtriking of the two Steels againſt each o
ther the leaſt ſpark of Fire: Nor did we
expect any (having before in vain attem
pted to ſtrike Fire this way in the open
Air) though we thought fit to make the
Experiment to undeceive thoſe who fan
cy in rarified Air, I know not what ſtrange
diſpoſition, to take Fire upon a much
ſlighter occaſion then this Experiment
afforded. We have indeed found, that
by the dextrous Colliſion of two har
den'd pieces of Steel, ſtore of ſparks
may be ſtruck out: But that was done with
ſuch vehement percuſſion of the edges of
the two Steels, as could not well be com
paſſ'd in our Receiver.
