applying the Wire thereof to the glafs Globe, and 
which is known by the Appearance of the Brufh of 
Flame at the End of the Wire, as before-mention'd ; 
hang a (lender Piece of Wire to the fufpended 
Gun-barrel for this Purpofe detached from the 
Globes. Upon your applying the Wire of the 
electrified Phial to that hanging to the Gun-barrel, 
you perceive a fmall Snap ; this you difcharge by 
touching the Gun-barrel with your Finger, which 
likewife fnaps : And thus alternately electrifying 
and difcharging, you proceed until the whole 
EkCtricity of the Water is diffipated s which fome- 
times is not done, under an hundred Difcharges. If 
you do not difcharge the EleCtridty every time, the 
Snaps from the W ire of the electrified Phial to the 
Gun-barrel are fcarcely perceptible. In proportion 
to the Number of Strokes, you eftimate the Quan- 
tity of the acquired Electricity of the Water. That 
you could, by (lopping the Eledricity, excite Non- 
electrics 5 and, by accumulating their Power, make 
them exert more Force than Originally eleCtrics 
would at any Point of Time, was that capital Dif- 
covery of the late Mr. Gray 5 and is to be regarded 
as the Bafis, upon which all the prefent Improve- 
ments of our Knowledge in Ele&ricity are founded; 
and till which Difcovery, although fome of the Ef- 
fects of EleCtricity were obferved above two thou- 
fand Years ago *,• little Progrefs was made.
