the Bell, and that of the Phial, were nearly in the 
lame horizontal Line 5 but the Bell was between fix 
or feven Inches from the Surface of the Phial. Every 
thing being in this State, the Bell remained quite 
Bill, if the Stand was very dry; but the Inftant one 
either approached a Finger, or any other non eledric 
Body, to the Wire of the Phial, the Bell leaped to 
it : and one might begin again, and repeat the Ex- 
periment twenty Times together, without having any 
Occafion to new-eledrify the Phial. 
With regard to the Propagation of Eledricity, the 
Velocity with which the eledrical Matter is convey’d, 
has been found too great to be yet determin’d with 
any Exadnefs. 
The Author made an Experiment with an iron 
Wire of 950 Toifes in Length, and He was not able 
to obferve, that there pafied fo much as a Quarter of a 
Second of Time, between the Wires receiving the 
Eledricity at one End, and his feeling the Shock in 
both his Arms at the other ; which infers a Velocity 
at lead thirty times as great as that with which Sounds 
are propagated. 
In feeking what might be the Force which fhot 
forward the eledric Matter, with fo much Rapidity, 
through the Length of the Wire, he at firft thought 
it might be performed by the Explofion of the Spark 
of Fire, which is perceived when theeledrified Phial 
is brought into Contad with the Wire conduding the 
eledric Matter; but the following Experiment foon 
convinced him he was miftaken. 
He difpofed horizontally a Wire folded in two, 
upen Lines of Silk ; the whole Length of this Wire 
was
