Wire was divided which was laid over the Bridge : 
Upon prefenting the iron Hook ro the Spirit, a fuf- 
ficicnt Snap was given to the Spoon to hre the Spi- 
rit, but nothing fo fmart as in the former Experi- 
ment where the large Circuit was completed. 
It was then tried, what the Effed would be upon 
the Spirit, if the charged Phial was divdb d ol its 
long Wire which lay over the Bridge, and was only 
held in the Hand of an Obferver j whilft the Spoon 
with warm Spirit was placed in Contad of the iron 
Rod before mention'd, to which the Wire was con- 
nected, which went to the Obfervers upon the 
Surry Shore; and the Spirit wasfired with much the 
fame Degree of Smartncfs as in the laft Experiment. 
In thele and all the fubfequent Operations, Wires 
were made ufe of to condud the Eledricity prefer- 
able to Chains, as it before by great Numbers of 
Experiments had been fully proved, that whatever 
Difference there was in the Bulk of the Conductor, 
that is to fay, whether it were a fmall Wire, or a 
thick iron Bar, the electrical Strokes communicated 
thereby were equally ftrong: And it had been fur- 
ther obferved, befides the Difficulty of procuring 
Chains of a requifite Length for the prefent Pur- 
pofes, that the Stroke at the Gun -barrel, when the 
Electricity was conducted by a Chain, was ceteris 
paribus not fo ftrong, as when that Power was con- 
ducted by a Wire. This was occafion’d by the 
Junctures of the Links of the Chain not being fuf- 
ftciently clofe, which caufed the Electricity in its 
Paffage to fnap and flafh at the Junctures, where there 
was the leaft Separation ; and thefe lefter Snappings 
in the whole Length of the Chain leffen’d the great 
one of the Gun-barrel.
