fufpended on if, being rubbed for fome Time, the 
Leaf-Brafs was attracted as manifeftly as it had been 
with much fhorter Lines. We then repeated the Expe- 
riment with the little Ihort folidCane, and found there 
was fomewhat of an Attra&ion, but not near fo great 
as with the large Tube. 
Though the going and returning of the EleCtrick 
Effluvia was very furprifing, yet we were willing to 
try how far the attractive Vertue might be carried in 
a continued right Line ; the Method of doing which 
was thus : That End of the Line where the Attraction 
was to be made, was fufpended on a Silk Line that was 
fixed crofsthe Garret Window on the North-fide of 
the Houfe, which was by Eftimation about forty Feet 
high ; at about an hundred Feet from hence two Rods 
or Poles of about ten Feet long, and at two Feet di- 
ftance from each other, were drove into the Ground, 
fo as that they flood nearly perpendicular. Thefe 
were in the great Garden. Beyond thefe, in the great 
Field, that is feparated from the Garden by a deep Fofs, 
about the fame Diftance from the firfl, were another 
Pair of Poles fixed ; then four others at a like Diftance. 
Uj n the Ends of thefe Poles were tied the crofs 
Lines of Silk, to fupport the Line of Communication, 
which being laid on the Silk Lines, the Ivory Ball 
hanging in the Garret Window, and the other End of 
the Line being hung by a Loop on the Tube, the Leaf- 
Brafs was held under the Ball, and after the Tube had 
been rubbed for fome Time, they called to me to let me 
know that there was an Attraction of the Leaf-Brafs. 
This was feveral Times repeated with Succefs ; then 
Mr. fVheler came into the Field, and rubbed the Tube 
himfelf.
