was done accordingly; but the Obferver felt no- 
thing, the Phial difcharging itfelf in a different 
manner to what it did before, on account of the 
Circuit's not being compleated. 
It was then tried, whether an Obferver would be 
(hocked 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 exploded very quick, becaufc the iron 
Wire conducted the Electricity better than the 
Body of the Obferver. 
It was then tried, whether or no, as the Ground 
was wet, if the Explofion was made with the Ob- 
ferver holding the Extremity of each Wire (landing 
upon the Ground near the Window of the Houfe, 
any Difference would arife in the Succefs of the 
Experiment. No Difference was found, the Ob- 
ferver being (hocked in the Infant of the Explofion, 
as before, in both his Arms, and acrofs his Bread. 
Upon thefe Confiderations we were fully fatif- 
fied, that through the whole Length of this Wire, 
being, as I mentioned before, twelve thoufand two 
hundred and feventy-fx Feet, the Velocity of Elec- 
tricity was inftantaneous. 
As it was found laft Year, we obferved again, 
that although the electrical Commotions were very 
fevere to thole who held the Wires, the Report of 
the Explofion at the prime Conductor was little, in 
comparifon of that which is heard when the Circuit 
is fhort. From whence it was conjectured, that the 
very loud Report, in the Experiment of Leyden is 
confined to a very fhort Circuit.
