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.

Page 28, line 2. The consequence might perhaps be fatal, &c. We have found it fatal to small animals, but 'tis not strong enough to kill large ones. The biggest we have killed is a hen.

Page 31, line 20. Ringing of chimes, &c. This is since done.

Page 33, line 22. Fails after ten or twelve experiments. This was by a small bottle. And since found to fail after with a large glass.
