a Piece of Lead ; then with larger Quantities of Metal, 
fufpending them on the Tube by Packthread. Here I 
made ufe of a Fire-Shovel, Tongs, and Iron Poker, * a 
Copper Tea-Kettle, which fucceeded the fame, whe- 
ther empty, or full of either cold or hot Water ; a 
Silver Pint Pot ^ all which were ftrongly Eleftrical, 
attracting the Leaf-Brafs to the Hight of feveral Inches* 
After I had found that the Metals were thus Electri- 
cal, I went on to make Trials on other Bodies, as Flint- 
Stone, Sand-Stone, Load-Stone, Bricks, Tiles, Chalk ; 
and then on feveral vegetable Subftances, as well green 
as dry, and found that they had all of them an Eledrick 
Vertue communicated to them, either by being fufpended 
on the Tube by a Line, or fixed on the End of it by 
the Method above-mentioned. 
I next proceeded to try at what greater Diftances 
the EleCtrick Vertue might be carried, and having by 
me Part of a hollow walking Cane, which I fup- 
pofe was Part of a Fifhing*Rod, two Feet feven 
Inches long ; I cut the great End of it, to fit it into the 
Bore of the Tube, into which it went about five Inches ; 
then when the Cane was put into the End of the Tube, 
and this excited, the Cane drew the Leaf-Brafs to 
the Hight of more than two Inches, as did alfo the 
Ivory Ball, when by a Cork and Stick it had been fix- 
ed to the End of the Cane. A folid Cane had the 
fame Effeft, when inferted in the Tube after the fame 
Manner as the hollow one had been. I then took the 
two upper Joints of a large Fifhing-Rod, the one of Spa . 
nijh Cane, the other partly Wood and the upper End 
Whale-bone, which, together with the Tube, made a 
Length of more than fourteen Feet. Upon the lefier
