Thread of Trial (mention’d in my former Papers) 
was drawn by the Lignum Vita at the Diftance o£ 
a Foot. 
Afterwardshaving join’d more Packthread together, 
I made a String of four hundred and twenty Foot long, 
one End of which I faften’d (by the Interpofition of 
Cat-gut as before) to the Iron Gates in the Garden, 
before the Houfe, and the End which had the Lig- 
num Vita Handle, to the upper Part of the Door next 
to the Back-fide of the Houfe in a large Drawing- 
Room, taking care that the String came through 
the middle of the open’d Doors through which it 
paired j and to prevent this String dragging upon the 
Ground, three Pieces of Cat-gut held acrofs by two 
Men, at equal Diftances from the Ends, and from each 
ether, fupported it. The String was altogether dipp’d 
in a Pail of Water, before the Experiment} but great 
Care taken, that the Cat-gut fhould not be wet. 
Then I applied the rubb’d Tube at the End in the 
Garden, whilft my Afliftant held the Thread of Trial 
near the Handle above- mention’d, which Thread was 
ftrongly attracted, though the Wind was very high, 
and blow’d in the contrary Direflion to that in which 
the Eledlricity ran along. 
I firft tried the Experiment with the Packthread dry, 
but then it would not do at that Diftance.

periment.
