on the Surry Shore was each time fmartly ftruck, 
the 'Prefident of the Royal Society , who obferved 
with the utmoft Attention upon the Wejhmnfter 
Shore, gave the Signal that he felt nothing. The 
Company was furprifed at this Want of Succefs in 
the Experiment j but, upon examining the Wire, 
which was laid over the Bridge, it was found to have 
been broken by fome Accident, after it had paffed 
over about a fourth Part of the Bridge. The Wire 
being refitted, it was agreed to make the fame Ex- 
periment fix times more : This was done accordingly, 
and the electrical Commotion was felt each time 
by the Obfervers on both Sides of the Water, but 
much fmarter by thofe on the Surry Side. It was 
then thought proper to repeat this Experiment three 
times more upon the Signal's being given : but, in 
making the firft of thefe, the Obferver in the Room 
with the Machine, difeharged the eiedrified Phial, 
before the Obferver upon the Surry Shore had dip- 
ped his iron Rod into the Water, and therefore no 
EfFed was perceived by the Obferver on the oppofite 
Shore. The eiedrified Phial therefore was again 
difeharged three other times, and the Commotion 
felt by the Obfervers on both Sides of the River. 
To examine the fecond Queftion, no other Alter- 
ation was ncceflary in the whole Apparatus , than 
that the Obferver upon the Wefiminfter Shore (hould 
not dip either his Hand, or the iron Rod held 
therein in the laft Experiments, into the Water of 
the River. The eledrified Phial then was difeharged 
three times without its EfFeds being in the lead 
perceiv’d by the Obfervers upon the Weftminfter 
Shore ; thofe indeed on that of Surry felt the Shock 
as before.
