is [mpregoated the greater will be the Diflatice; and 
if then the Non-electric is brought nearer, the Sparks 
will be fmaller, but fucceed each other quicker } fo 
that when it is brought almolt to touch the Rod, 
they will appear like a fmall Stream. The Reafon 
of which 1 take to be, that as the eleCtric Atmo- 
fphere furrounding the Rod isdenfer nearer it than far- 
ther off, when the Non-eleCtric is brought into fo very 
die nfe a Part of the Atmofphere, it will from thence 
become nearly as electrical as the Rod itfclf; and 
therefore lofe great Part of its attractive Force, and 
confequently will only be able to draw off thole 
Particles from the Rod which are neareft to it. 
1 would farther take notice, that the Sparks are 
always produced in the Space between the Non- 
electric and the Rod, and often appear as iffuing 
from the Non eleCtric. This Appearance is proba- 
bly owing to thofe Particles, which, by their Elas- 
ticity, are reflected back again from the Non-eleCtric 
towards the Rod, and which, by (hiking againft 
thofe coming from it, produce both the Sparks and 
Noife that is heard * and as I have already fhewn, 
that the Particles often appear in. luminous Rays at 
the Point of the Non-eleCtric, it thence happens, 
that the Spark is frequently kindled fo near to the 
Non, eleCtric, as to appear as ifluing from ir. 
I obferved, in my former Paper, that feveral in- 
genious Gentlemen, from this Appearance of a Light 
st the Point of the Non-eleCtric, have imagined 
there was a Current of electrical Effluvia continu- 
ally ifluing out of it, and which, fetting in towards 
the electrified Rod, was the Caufe of the Attraction 
of the Electricity: And this Conjecture of theirs
