the River as before; but the Obfcrver at E was 
placed in a dry gravelly Field about 300 Yards nearer 
the Machine than his laft Station, and about 100 
Yards diftant from the River. He there flood upon 
the Wax, holding the condu&ing Wire in one 
Hand, and touched the Ground with an iron Rod 
held in the other. The Shock was each time felt 
by the Obferver at 2), but fenftbly weaker than in 
the former Trials; but the Obferver at E felt them 
all equally ftrong with the former ; the four firft in 
his Arms, when he flood upon the Wax, and 
touched the Ground with his iron Rod; the other 
four in his Arm and Ankles, when he flood upon, 
the Ground without the iron Rod. 
In forne of thefe Experiments, the Obfervers at 
2 ) felt a Tingling as foon as they laid hold of the 
conducing Wire. This was conjedured to be owing 
to the Eledricity, which conftantly runs off while 
the coated Phial is filling, and preferably by the 
Wire, as the beft Condudor. 
From the Severity of the Shock, the Gentlemen, 
in fome of thefe Trials, did not choofe to have the 
Eledricity pafs through their Bodies : But, as it was 
neceffary for them to be fenfible of the different 
Degrees of the eledrical Commotions, they bound 
the conduding Wire round one of their Thumbs, 
and touched the iron Rod with the Fore-finger of 
the fame Hand 3 when the eledrical Commotion was 
felt only in fo much of the Finger and Thumb of 
that Hand, as completed the Circuit. 
By the Experiments of this Day, the Gentlemen 
were fatisfied, that the dry gravelly Ground conduded 
the Eledricity as ftrongly as Water ; which, though
