Additional experiments: proving that the Leyden bottle 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 positive state. 245
