Effects of the Electrical Matter, and the Means of

preserving Buildings, Ships, &c. from Lightning,

arising from Experiments and Observations made

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
