Hands, if Mr. T)ufay had not appeared upon the 
fame Subject, in three Propofitions, and a few Co- 
rollaries. I am, Sir, with a very great Regard, 
Bodies made Ele^rica!, by communicating with an 
Ele^rical Body excited by FriBion, are in a 
State of Repuljion with regard to fuch excited 
Bodies. 
I hung a fine white Thread by a Loop, to an hori- 
zontal blue Silk Line, about four Feet long, tied at 
each End, and at about a Foot diftance from it, 
placed a Glafs Tube two Feet and a half long nearly, 
and one Inch and quarter Diameter, fixed in the 
Centre of a circular Piece of Wood fupported upon, 
three brafs Skrews, fo that the Tube and pendulous 
Thread were parallel to each other. The Tube being 
rubbed, the Thread was attraded and repelled Seven 
or Eight times (in very good Weather, I have ob- 
ferved it move to and from the Tube Twelve times, 
at above one Foot Diftance), I then tied a Piece of 
new fmooth Packthread to the Top of the Tube, and 
to the Loop of the Thread hanging down as before, 
and again excited the Tube : The Thread, without 
coming once towards the Tube, went into and con- 
Ottefden-Vlace. 
Tour much obliged, 
humble Servant,
