lower end of it\ it would be attracted by it at the 
diflance of ^ or 6 Inches; but at fome times the Elect- 
ricity would be much weaker than at others, the rea- 
fon of which I conje&urd to be, that the Ribband 
might have imbibed fome aqueous Particles from the 
moift Air, which I found to be upon trial the occafion 
of it ; for when I had well warmed the Ribband 
by the Fire, it never failed to be Rrongly, Eled- 
rical. 
After this I made trial of feveral other Bodies, as 
Linnen of feveral forts, viz. Holland, Mulling, &c- and 
Woollen, as of feveral forts of Cloth and other Stuffs 
of the lame Materials. From thefe I proceeded to 
Paper, both white and brown, finding them, after 
they had been well heated before rubbing, to emit co- 
pioufly their Ele&rick Effluvia. The next Body that I 
found the fame Property in, was thin fhavings of Wood ; 
I have only as yet tried the Fir Shavings, which are 
flrongly Eledrical. The three lafl Subftances which I 
found to have the fame Property, are Leather, Parchment, 
and thofe thin Guts wherein Leaf-Gold is beaten. 
All thefe Bodies will not only by their Electricity be 
drawn to the Hand, or any other folid Body that is 
near them; but they will, as other EleCtrick Bodies do, 
draw all (mail Bodies to them, and that to the diflance 
of fometimes 8 or io Inches. Heating them by the 
Fire before rubbing very much increafes their Force. 
There is another Property in fome of thefe Bodies, 
which is common to Glafs, that when they are rubbed 
in the dark, there is a Light follows the Fingers through 
which they are drawn ; this holds both in bilk and Lin- 
nen, but is flrongefl in Pieces of white prefhng Papers, 
which are much the fame with Card Paper ; this not only 
yields a Light as above, but when the Fingers are held 
near it, there proceeds a Light from them with a crack- 
ling
