the Elafticity of the eledrical JE ther overcomes the 
Attradion of Cohefion : I have frequently obferved 
this Experiment does not operate, unlefs the greateft 
Part, if not the whole eledrical Blaft, is determined 
to the Floor through the Water, by bringing feme 
unexcited Non-eledric near the long Leg of the 
Siphon f. The Stream through this (lender Tube 
is mod complete, when the Non-eledric is brought 
near, fo as when the Room is fomewhat darkened, 
tha Stream of Water appears as a Stream of blue 
Flame, much like that from the blunt Wire. This 
Stream is (lopped, either by touching any Part of the 
Non-eledrics in Contad with the Globes 5 by place- 
ing the Machine and the Man who turns the Wheel 
upon Eledrics fe , by which the Current of the 
eledrical iEther from the Floor to the Machine is 
prevented s or by removing the Non-eledric from 
the Leg of the Siphon, by which the Diffipation of 
the eledrical AEther from the excited Non-eledric 
becomes general. So that we find, that although 
we can repel light Bodies from many Parts of ex- 
cited Non-eledrics at the fame times the whole 
Force of the eledrical Current is necefiary, to drive 
off 
f There is one Inftance, where the Water will run off in a full 
Stream without bringing a non-elecffric unexcited near the long 
Leg of the Siphon ; and that is, by fufpending a Phial of Water, 
as ufual to the Gun-barrel by a Wire, and by letting a glafs Siphon 
through the Cork into the Water. When this Phial is fufficiently 
electrified, the Water therein runs off in a full Stream, though no 
Non-ele£tric unexcited is near; becaufe then the Current of Water 
^through the Siphon is the only Way, by which the Surcharge of 
the Electricity can be difiipated.
