the lignum vitae handle, to the upper part of the door next to the back-side of 

 the house in a large drawing-room, taking care that the string came through 

 the middle of the opened doors through which it passed ; and to prevent this 

 string dragging on the ground, three pieces of cat-gut held across by two men, 

 at equal distances from the ends, and from each other, supported it. The 

 string was altogether dipped in a pail of water, before the experiment ; but 

 great care was taken, that the cat-gut should not be wet. 

 . Then he applied the rubbed tube at the end in the garden, while an assistant 

 held the thread of trial near the handle abovementioned, which thread was 

 strongly attracted, though the wind was very high, and blowed in the contrary 

 direction to that in which the electricity ran along. 



He first tried the experiment with the packthread dry, but then it would not 

 dp at that distance. The weather was moist when he made the experiment.
