feet long, and was carried from thence to the fteeple 
of the town ; where it was likewife fatten'd to an- 
other fllken cord of eight feet long, and fhelter’d from 
rain : and a large key was fufpended by the end of 
this wire, in order to receive the electrical fluid. 
Obfervation i. 
From the 17th of June, the time of beginning my 
experiments, the electricity of the air was lenfibly felt 
every day, from fun-rife, to 7 or 8 in the evening ; 
except in moift weather, when I could perceive no 
figns of electricity. In dry 'weather, the wire at- 
tracted minute bodies, at no greater diftance than 
three or four lines. I repeated the experiment care- 
fully every day, and conftantly obferved, that, in wea- 
ther void of florms, the electricity of a piece of feal- 
ing-wax of two inches long was above twice as ftrong 
as that of the air. This obfervation inclines me to 
conclude, that, in weather of equal drinefs, the elec- 
tricity of the air is always equal.

When I grafped the wire clofely in my hand, the 
electricity ceafed inftantly, and did not recover till 
three or four minutes after: whereas, during a florin, 
we could deprive the wire of its eleCtricity but a mo- 
ment j for it immediately return’d with the fame vi- 
gour. Whence it appears, that the common electri- 
city of the air has but a flow motion.

I endeavoured to increafe the electricity of my wire, 
by the addition of a fecond, which communicated
