of the iron Rod. Upon the Explosion they were 
all fo ftrongly fhocked in their Arms and Ankles, 
that the Countrymen could by no means be pre- 
vailed upon to try the Experiment again. Why, in 
the fir ft eight Explolions, the Oblervers here were 
ienfible o t the electrical Commotion, when the 
Obfcrvers at the other Station felt nothing, was ex- 
plained in the former Experiments. The Obfervers 
at this Station, from their Situation under the Hill, 
and from what Wind there was being againft it’ 
never heard the Report of the Gun. 
Though the Obfervers near the feven Mile-Stone 
from the breaking of their Wire, were not fenfible 
ol the eight firft Explofions of the charged Phial, 
they felt the other twelve. This demonftrated to 
the Satisfaetion of the Gentlemen concerned, that 
the Circuit here formed by the Electricity was four 
Miles 3 viz. two Miles of Wire, and two Miles of 
Ground, the Space between the Extremities of that 
Wire. A Diftancc without Trial too great to be 
credited ! How much further the eledrical Commo- 
tion will be perceptible, future Obfervations can 
only determine. 
The electrical Commotion by the Obfervers near 
the feven Mile-Stone was but (lightly felt; nor 
could it be otherwife expeded, the Wire in many 
Parts of its Length touching, as was before-mention’d, 
the moift Vegetables; which, in as many Places as 
they were touched, formed fubordinate Circuits. 
We find, in all other Inftances, that the whole Quan- 
tity of Electricity, accumulated in the coated Phial, 
is felt equally through the whole Circuit, when 
every
