the Electricity palled both through thei'r Legs, and 
thro’ the Iron :In the third, when they hood upon the 
Ground without either Wax or Rod, the Electricity 
directed its Way through one Arm, and through 
both Legs to complete the Circuit. 
The Gentlemen were delirous of doling the pre- 
fent Inquiry, by examining not only whether or no 
the electrical Commotions were perceptible at dou- 
ble the Diftance of the laft Experiments in Ground 
perfectly dry, and where no Water was near s but 
alfo, ifpohible, to dihinguifh the refpe&ive Velocities 
of Electricity and Sound. To execute this, required the 
whole Sagacity and Addrefs of the Gentlemen con- 
cerned 5 for they had met with very great Difficul- 
ties in the laft Day s Operations, where the Wire 
was conducted but little more than a Mile 5 all 
which could not but be greatly augmented by dou- 
bling that Diftance 5 becaufe it was neceflary, that 
the Houfe, wherein the electrifying Machine was 
placed, fhould be vifible at leaft at one of the Sta- 
tions 5 and that the Space between that Houfe and 
the Stations, through which the Wire was con- 
ducted, fhould be very little interfected by Hedges, 
Roads, or Foot-paths 5 neither fhould the Wirepin 
this Space be fubject to be difturbed by the Horfes 
or Cattle,, which were grazing j nor ought it to 
touch in its Paflage the Trees or any other Ve- 
getables, which at this Seafon of the Year were 
every-where luxuriant. To find a Place within a 
convenient Diftance of London with thefe Requifites 
was not very eafy ; but at laft, Shooters Hill was, 
pitched upon, as the moft convenient.
