Electricity at a certain Diftance 5 becaufe, although 
iaft Year, in meafuring the refpe&ive Velocities of 
Llecliicity and Sound, the lime oi its Pro^refs was 
found to be very little, yet we were ddirous of 
knowing, (mall as that Time was, whether it was 
meafurable 5 and I had thought of a Method for this 
Purpofe. 
^ Accordingly, Augufl 5. 1748. there met at 
Shooter's Util for this Purpofe the Trefident of the 
Royal Society , the Rev. Mr. Birch , the Rev. Mr. 
Profefibf Bradley , James Burrow Efq; Mr. E lit cot, 
Mr. George Graham , Richard Graham Efq; the Rev* 
Mr. Lawrie , Charles Stanhope Efq; and mvfelf, who 
were of the Royal Society , Dr. Bevis , and Mr. 
Grijchow a Member of ‘the Royal Academy of 
Sciences at Berlin. 
It was agreed to make the electrical Circuit of 
two Miles, in the middle of which an Obferver was 
to take in each Hand one of the Extremities of a 
Wire, which was a Mile in Length. Thefe Wires 
were to be fo difpofed, that this Obferver being 
placed upon the Floor of the Room near the electrh 
fying Machine, the other Obfervers might be able 
in the fame View to fee the Explolion of the charged 
Phial and the Obferver holding the Wires, and might 
take notice of the Time lapfed between the difeharge- 
ing the Phial and the convulfive Motions of the 
Arms of the Obferver in confequence thereof 5 in- 
afmuch as this Time would fhew the Velocity of 
Electricity, through a Space equal to the Length of 
the Wire between the coated Phial and this Ob- 
ferver,
