Space of Time, and the Wire again hung perpendi- 
cularly from my Finger, though the Globes continued 
in Motion. This induced me to believe, that the 
Gun-barrel, and the other Non-electrics fufpended in 
Contadt with the Globes, would only contain a cer- 
tain Quantity of the ele&rical iEther 5 and if this 
were the Cafe, the Attra&ion of the Wire to the 
Machine would be continual, if the ele&rical Power 
found again a Communication with the Floor, as 
the Wire was the only Canal of Communication 
between the Floor and the Machine. Whereupon I 
placed one of my Fingers upon the Gun-barrel, and 
held a Wire near the Machine with my other Hand, 
and found, that as long as my Finger continued 
upon the Gun-barrel, the Wire was attra&ed, but 
no longer. 
4 S>. Here we find, that one Caufe of the ele&ri- 
cal Attraftion is the Current of the eledtrical iEther 
fetting to the Machine through the Wire; and this 
Current is flopped from two Caufes; one, when 
there is no Difcharge thereof from the Gun- barrel, 
the Accumulation being complete 5 the other, when 
other Currents are opened, that is, when the Machine 
is touched in other Parts. 
50. in thefe, and the fubfequent Experiments, I 
always fuppofe the Air very dry 3 for if it is not, 
and the filk Lines, which fupport the Non-eledtrics, 
are wetted thereby, the eiedtrical Power will be di£ 
charged along them, and the Wire will be conftantly 
attracted, as 1 have frequently on purpofe expe- 
rienced ; and this Difcharge is in proportion as the 
Lines are more or lefs wetted.
