of his Hands to the Phial, touches the electrified 
Gun-barrel with a Finger of his other, let the Phial 
be ever fo ftrongly electrified, he feels but a flight 
Stroke s and this Stroke is greater or lefs, in pro- 
portion to the Difference of the Accumulation of 
Electricity in the Body of the Man, and that of the 
Water in the Phial. Thus we know from Experi- 
ment, that though a confiderable Quantity of the 
Electricity, in impregnating the Phial of Water 
therewith, pervades the Giafs, yet the Lofs thereof 
this Way is not equal to what comes in by the 
Wire : Therefore we will, for the fake of a more 
eafy Method of Explanation, fuppofe, that the Phial, 
when electrified in the moft perfect manner, con- 
tains a Quantity of Electricity equal to io; that the 
Mans Body, by ftanding upon Wax, and touching 
the Phial with one of his Hands during its Electri- 
fication, contains a Quantity equal to 7 : Upon h\$ 
touching the Gun barrel with a Finger of his other 
Hand, he will receive a fmall Stroke only equal to 
3, the Difference of the Electricity of the Water 
and that of his Body ; And if he touches the Gun- 
barrel again, without removing his Foot from the 
originally Electric, the Stroke will be fcarcely per- 
ceptible, on account- of his Body being nearly of 
the fame Degree of Electricity with the Water in 
the Phial. So that here we fee that the Violence 
of the Shock, to be felt by whatever forms the 
curve Line, depends upon its being, in the moft per* 
feet manner, free from any Degree of Electricity more 
than the original Quantity 5 which is contrary to the 
Opinion of our Author.
