days I procured a Stick of the beft black Sealing- wax, 
of about an Inch in Thick, nefs, and of a convenient 
Length $ and exciting it with white-brown Paper, or 
clean dry Flanel (I know not which is beft) I made 
the following Trials. 
I attempted to kindle common Lamp Spirits, both 
by Attraction and Repulfion, the electrified Perfon 
handing on a Cake of Bees- wax, and fucceeded. — - 
I made Trial, at the fame time, with my gl^fsTube, 
and, I think, kindled the Spirits more eafily. Per- 
haps, from fome Circumftances hereafter to be men- 
tioned, this may, cater is paribus , be generally ex- 
petted. 
I was then minded to repeat that Experiment of 
the late ingenious and induftrious Dr. DefagufoerSy 
and others 5 by which it appears, that when any 
light Body is put into a State of Repulfion by vitre- 
ous Elettricity, it is in a State of Attrattion, in rc- 
fpett of refinous Elettricity, and fo e contra . This 
I found conftantly to hold good. I made this Trial 
With a Down- Feather, whicl\ was tied to the End of 
a pendulous Thread, which Thread was tied to a filk 
Line, fattened horizontally to the oppofite Sides of 
the Room, and alfo with a fmall Piece of writing 
Paper, of about the fame Dimenfions as the Feather. 
Here I found the Feather would retain the Effluvia 
(whether of the Tube or Cane) about five or fix 
Minutes longer than the Paper would; that is, the 
Feather remained fo much longer in a State of Re- 
pulfion. The Time in which the Paper was in a 
State of Repulfion, after many Trials, I found to-be 
about twenty iMinutes, more or lefs; at about which 
time the Paper would indeed fomewhat knfibly de- 
cline
