from an excited Eledrical Body ; but does not retain 
it whilft it touches any other Non-cledrical Body. 
An Eledric per fe , when it is become Non-eledrical, 
differs from the Non-eledric per fe in this ; that it 
may be fo reftor'd to Eledricity, by applying a rubb’d 
Tube to it, as to repel all other Eledrics of the fame 
kind of Eledricity as the Tube ; till it meets with 
fome Non-eledric Body, which brings it back to 
Non-eledricity, or at lead to fuch a languid State, that 
its Eledricity is fcarce perceptible. 
The Eledricity may be alfo reftor'd in the fame 
manner by Wax, &c. But in both Cafes, an Eledric 
Body, in a languid State, cannot be reftor’d to Elec- 
tricity whilft it adheres to a Non-eledric per fe . 
Experiments to ill ujt rate tftefe Ajferttom . 
Prom an horizontal Cat- gut (which is an Eledric 
per fe , as mod Animal Subftances are) I fufpended 
two Feathers, the one by a Thread, and the other by 
a Silk, about two Foot long each : Then applying the 
rubb’d Tube to the Feather hanging by the Silk, 
(which Silk is an Eledric per fe) the Feather came 
to the Tube, and ftuck to it, as all Non-eledric Bodies 
do, till it was fo impregnated with the Virtue from 
the Tube, as to come out of its languid State, and 
become ftrongly Eledrical ; which appear’d by its 
flying from the Tube, and being repell’d as often as 
the Tube was brought near it; till it had touch’d 
fome Non-eledric Body, or was left fo long as to 
imbibe the moifl Particles floating in the Air; by 
which it became Non-eledric^ and was again attraded 
by the Tube.
