But if the fire, with which the inside surface is surcharged, be so much precisely as is wanted by the outside surface, it will pass round through the wire fixed to the wax handle, restore the equilibrium in the glass, and make no alteration in the state of the prime conductor.
Accordingly we find, that if the prime conductor be electrified, and the cork balls in a state of repellency before the bottle is charged, they continue so afterwards. If not, they are not electrified by that discharge.

to the Preceding Papers.
[Page 2], Sect. 1. We since find, that the fire in the bottle is not contained in the non-electric, but in the glass. All that is after said of the top and bottom of the bottle, is true of the inside and outside surfaces, and should have been so expressed. See Sect. 16, [p. 16].
[Page 6], Line 13. The equilibrium will soon be restored but silently, etc. This must have been a mistake. When the bottle is full charged, the crooked wire cannot well be brought to touch the top and bottom so quick, but that there will be a loud spark; unless the points be sharp, without loops.
Ibid. line ult. Outside: add, such moisture continuing up to the cork or wire.
[Page 12], line 14. By candle-light etc. From some observations since made, I am inclined to think, that it is not the light, but the smoke or non-electric effluvia from the candle, coal, and red-hot iron, that carry off the electrical fire, being first attracted and then repelled.
[Page 13], line 15. Windmil wheels, &c. We afterwards discovered, that the afflux or efflux of the electrical fire, was not the cause of the motions of those wheels, but various circumstances of attraction and repulsion.
[Page 16], line 21. Let A and B stand on wax, &c. We soon found that it was only necessary for one of them to stand on wax.
