of chocolate being turned out of the tin pan, in which it 
had been fet to cool; I prefented towards it Mr. can- 
ton’s electrometer, and obferved that, at fix inches dis- 
tance, the balls began to diverge ; and when they came 
within two inches of the chocolate (being fufpended over 
it) their divergence was full an inch and an half, and upon 
examining their electricity, I found the chocolate to be 
in a plus or pofitive ftate. 2dly, Having Separated another 
large cake from the pan, I touched it repeatedly with 
the knob of a fmall phial, properly prepared for the 
Leyden experiment; then bringing that knob gently 
toward one of my knuckles, I faw a fpark between them, 
and had a fmall fenfation in my knuckle. 3dly, Having 
Separated another cake of chocolate from the tin pan 
which contained it, 1 touched the cake repeatedly with the 
brafs ball on the neck of my Leyden vacuum, or analyfis 
of the Leyden bottle and inftantly perceived a moft 
beautiful and large pencil of rays darting from the wire, 
and Spreading themfelves through the bulb towards the 
coated part of the bottle. 4thly, Changing the pofition of 
the bottle, I prefented the coated bulb towards the cho- 
colate,, and then perceived (as I expected) a fmall lumi- 
nous fpark upon the point of the wire in the neck of the 
bottle; completely proving the electrical quality of the
