otherwife at firft conjedured, they now found not 
to be needfary to convey that Power to great Di- 
ftances ; as well as that, from Difference of Dillance 
only, the Force of the eledrical Commotion was 
very little if at all impaired. They were convinced 
of the Truth of the lirlt of thefe Fads, not only 
from both Obfervers feeling the eledrical Commo- 
tion in the eight la'll Experiments, when the Ob- 
ferver at E was at fuch a Dillance from the Water, 
but alfo from the Obferver at E> feeling the Shock 
fo flrong in four of the firll fix Explofions, when 
the conduding Wire to E being broke at about 
ioo Yards Dillance from the Floufe, that Obferver 
felt nothing. 
In this lad Inllance the Circuit was formed from 
the Phial by the Obferver at *D and his Wire, a 
Line of Ground which reached from the Station at 
C E to the broken Wire that lay upon the Ground, 
and fo much of this Wire as reached to the fhort 
iron Rod, which touched the Gun-barrel in making 
the Explofions. This induced the Gentlemen to. 
conclude (as from many Experiments it was mani- 
feft, that when the intervening Subllanccs condud 
Electricity equally well, the Circuit was performed 
in the fhortdl manner poffible), that when the Ob- 
fervers holding their iron Rods in the River at j D 
and E were both fhocked, the Eledricity was not 
conveyed by the Water of the River, being two 
Miles in Length, but by Land, where the Dillance 
was only one Mile 5 in which Space that Power 
mull necellarily pafs over the New River twice, 
through feveral Gravel- Pits, and a large Stubble- 
Field. So that, admitting the Electricity did not
