him on Hair-Lines. There was taken two Pieces of 
white Rofin made into round fiat Cakes of fomewhat 
more than eight Inches Diameter, and two Inches 
thick. Thefe were laid down on the Floor of my 
Chamber, fo near together, that the Boy might ft md 
with one Foot upon one, and the other upon the other 
Cake of Rolin : Then the Leaf.Brafs being hid un- 
der his Hands, the Tube rubb’d and held near 
his Legs, caufed both his H inds to attraCt and repel 
the Leaf-Brafs to the Height of feveral Inches: Or 
if there was 1 lid Leaf-Brafs under one Hand, and the 
Tube held near the other Hand, there was an At- 
traction communicated to the farther one ; and when 
the Tube was applied either to his Hands or Feet, 
there was an Attraction given to his Cloaths ; fo 
that a Piece of white Thread being held by one 
End, the other End would be attracted at near the 
Distance of a Foot*, fo that the Attraction is altoge- 
ther as flrong, if not (Longer, than when the Boy 
was fufpended on Hair-Lines. 
I come now to the above-mentioned Experiment: 
One of the Boys being fufpended on the Hair-Lines, 
and the other (landing upon the two Cakes of Rofin, 
the Boys holding Hands with each other, under the 
Boy’s Hand that Rood on the Rofin was laid the Leaf- 
Brafs ; then the Tube being rubb’d, and held near 
the Boy's Feet that hung on the Hair-Lines, the Hand 
of the Boy that flood on the Rofin attracted (trongly. 
Then there was taken a four Foot Rule, and given to 
the Boys to hold by each End, and there was the 
fame Vertue of Attraction given to the other Boy as be- 
fore. After this a Line of Packthread was given them 
to take hold of by the Ends, and there was an At- 
traction
