at Philadelphia, 1749.- Golden Fish. - Extrac-

Additional Experiments; proving that the Leyden Bot-
tle has no more Electrical Fire in it when charged,
than before; nor less when discharged; that, in
discharging, the Fire does not issue from the Wire
and the Coating at the same Time, as some have
thought, but that the Coating always receives what
is discharged by the Wire, or an equal Quantity;
the outer surface being always in a Negative State
of Electricity, when the inner Surface is in a Posi-
tive State
