Yards for their Turns round the Sticks, amounted to 
two Miles a Quarter and fix Chains, or 12276 Feet. 
As the Night preceding thefe Experiments had been 
very rainy, Care was taken, by filk Lines properly 
difpofed, that the Wires in their Paffage from the 
Window of the Houfe might not touch the Wood 
thereof 5 left, from the Moifture of this Wood, the 
electrical Circuit might be fhortened. 
When all Parts of the Apparatus were properly 
difpofed, feveral Exploftons of the charged Phial 
were made 5 and it was invariably feen, that the 
Obfcrver holding in each Hand one of the Extre- 
mities of thefe Wires was convulfed in both his 
Arms in the Inftant of making the Exploftons. 
Inftead of one, four Men were then placed hold- 
ing each other by the Hand near the Machine, the 
firft of which held in his right Hand one Extremity 
of the Wire, and the Jaft Man the other in his left. 
They were all feen convulfed in the Inftant of the 
the Explofton. Every one who fell it, complained of 
the Severity of the Shock. 
It was then defired by one of the Gentlemen con- 
cerned, that an Explofton fhould be made with the 
Obferver holding only one of the Wires. This was 
done accordingly 5 but the Obferver felt nothing, the 
Phial difeharging itfelf in a different manner to what 
it did before, on account of the Circuit’s not being 
completed. 
It was then tried, whether an Obferver would be 
fhocked upon the Difcharge of the Phial, if the two 
Wires at their Extremities (lightly touched each 
other, whilft an Obferver at the fame time held one 
of thefe about a Foot from their Ends in each of his 
Hands? Upon Trial he felt nothing, though the 
Phial
