vity. Was this the Caufe, the Adion of Gravity 
would operate as much thro’ Originally-eledrics as 
through Non-eledrics. 
6o. But I am able to prove the Afflux experi- 
mentally, as well as the Efflux, in the following 
manner. When the Silver lies ftill, though the Mo- 
tion of the Globes is continued between the two 
Plates, one fufpended to the Gun-barrel, and the 
other placed upon an eledrical Cake, a Perfon (land- 
ing upon the Floor needs only bring a fmall glafs 
Siphon in a Veffel of Water, and apply the long 
Leg thereof near the Plate placed upon the Wax 5 for 
upon this the Silver is immediately fufpended 5 and 
the Water, which before only dropp'd, now runs 
in a full Stream, and appears luminous*. Does 
not, in this Cafe, the Current of the Water point 
out the Diredion of the Current of eledrical 
AEther ? 
6 x. When the Machine, &c. are placed upon 
Originally-electrics, if a Man, (landing likewife up- 
on an Originaliy-electric, touches the Gun-barrel 
while the Globes are in Motion, he will receive 
a Snap or two 5 after which, though the Motion 
of the Globe is continued, he will perceive no 
more Fire from the Gun-barrel. While in this 
Pofture, 
* This Experiment is more elegant, if the upper Plate, at- 
trading the Silver, is fufpended high enough for a Perfon (landing 
upon an Qriginally-eledric, conveniently to bring the other Plate 
under it with one Hand?, and to hold 3 pevder Plate in the other. 
If the Originally-eledric is fufficiently thick, the Silver will not be 
fufpended ; but if the glafs Siphon in a fmall Veffel of Water is 
brought very near the pewter Plate, the Water runs into the Plate* 
and the Silver is immediacy fufpended.
