pa (Ted over it in its Vibrations, the Leaf-Brafs would 
follow it, till it was carried off the Board : But thefe 
Experiments are difficult to make in the open Air, the 
leaft Wind that is ftirring, carrying away the Leaf- 
Brafs. 
Some Time after I made feveral Attempts to carry 
the Eleftrick Vertue in a Line horizontally, fince I 
had not the Opportunity here of carrying it from 
greater Hights perpendicularly, but without Succefs, 
for want of then making ufe of proper Materials, as 
will appear from what follows. The firft Method I 
made Trial of, was by making a Loop at each End of 
a Line, and hanging it on a Nail drove into a Beam, 
the other End hanging downwards, through the Loop 
at this End the Line with the Ivory Ball was put j the 
other End of this Line was by a Loop hung on the 
Tube; fo that that Part of the Line next the Ball hung 
Perpendicular, the reft of the Line Horizontal : Then 
the Leaf-Brafs being laid under the Ball, and the Tube 
rubbed, yet not the leaft Sign of Attraction was per- 
ceived. , Upon this I concluded, that when the Elec- 
trick Vertue came to the Loop that was fufpended on 
the Beam, it went up the fame to the Beam ; fo that 
none, or very little of it at leaft, came down to the Ball, 
which was afterwards verified, as will appear by the 
Experiments that will be mentioned hereafter. Upon 
this I gave over making any farther Attempts of car- 
rying the Eleftricity horizontally, defigning at my Re- 
turn to London , if I could get A.ffiftance, to have tried 
the Experiment from the Top of the Cupola of St. 
Paul's , not doubting but the Eleflrick Attraction
