LETTER II. 
SIR, 
T H E Subjeil of Eledrical Attraction at a Di- 
fiance, without any ContaCt of the Line of 
Communication either by the Tube, or the faid Line 
not touching the Attra fling Body, being fo very fur- 
prizing, I prefume the following Account of the 
Experiments 1 havefince my laft made on that SubjeCt, 
may not be unacceptable to the Society. 
A fmall Hoop of about twenty Inches Diameter, 
and an Inch and a half in Breadth, being fufpended 
by two Threads of Silk, fo as that it hung perpen- 
dicular, and in a Plane at right Angles to the hori- 
zontal Line of Communication, which pafs'd through, 
or at lead very near to the Center of the Hoop, 1 
went to the End of the faid Line, and applying the 
excited Tube near it, there was an attractive Influ- 
ence communicated to the Hoop in all Parts of it. 
Then by a Skrew-Hole made in the Side of the 
Hoop for that Purpofe, I fkrewed it upon the Top of 
a Pedeftal that was about two Feet and a half in 
Height, fetting it upon a Cake of Rofin, fo as that 
the before mentioned Line might pafs through the 
Center of the Hoop, and found that whether the 
Hoop was placed fo as its Plane was at right Angles, 
or in any other Angle with the Line of Communica- 
tion, the Hoop attrafled after the fame manner as it 
had done when fufpended on the filk Lines. 
Some time after I made the following Experiment. 
Into the Nofe of a Glafs Funnel I put the larger
