therefore, that one of the young ladies would fuf- 
fer the experiment to be made upon her head, 
which flie agreed to. The condudlor was then 
infulated as before, and the lady having placed 
herfelf fo, that the back part of her head almoft 
touched the brufh of wire, I defired her filler to 
Hand behind her, on a cake of bees -wax ; who, as 
foon as Hie began to comb the hair of the former, 
the conductor emitted fparks ftill of a larger fize 
than thofe we had hitherto feen. The hair was 
extremely electric, and when the room was 
darkened, we could perceive the fire pafs from it 
along the fmall wires to the conductor. The 
young lady who was on the wax, was not a little 
furprized to find, that the moment fhe began to 
comb her filter’s hair, her own body became 
eledtric, darting out fparks of fire againlt every 
fubltance that approached her. We found, how- 
ever, that thefe fparks were not Itrong enough to 
fire fpirits. I then coated a fmall phial, and loon 
charged it from the conductor ; but afterwards I 
did it more compleatly from the hair itfelf in the 
following manner. I fixed a brufh of fmall wires 
to the large one that went through the cork of 
the phial ; and taking the phial in my hand, I 
followed every motion of the comb with the brufh 
of wires; and, in the dark, could obferve the fire 
pafs by thefe wires into the bottle. . In a few mi- 
nutes I found it was highly charged ; when tak- 
ing a fpoonful of warm fpirits in my left hand, 
and with my right, which grafped the phial > 
bringing the hook of the great wire near the lur- 
face of the fpirits, a large fpark darted from it,
