candles, just blown out, by drawing a spark among the smoke between the wire and snuffers. We represent lightning by passing the wire in the dark over a China plate that has gilt flowers, or applying it to gilt frames of looking-glasses, etc. We electrize a person twenty or more times running, with a touch of the finger on the wire, thus: He stands on wax. Give him the electrized bottle in his hand. Touch the wire with your finger and then touch his hand or face; there are sparks every time. We increase the force of the electrical kiss vastly, thus: Let _A_ and _B_ stand on wax, or _A_ on wax and _B_ on the floor; give one of them the electrized vial in hand; let the other take hold of the wire; there will be a small spark; but when their lips approach they will be struck and shocked. The same if another gentleman and lady, _C_ and _D_, standing also on wax, and joining hands with _A_ and _B_, salute or shake hands. We suspend by fine silk thread a counterfeit spider made of a small piece of burnt cork, with legs of linen thread, and a grain or two of lead stuck in him to give him more weight. Upon the table, over which he hangs, we stick a wire upright, as high as the vial and wire, four or five inches from the spider; then we animate him by setting the electrical vial at the same distance on the other side of him; he will immediately fly to the wire of the vial, bend his legs in touching it, then spring off and fly to the wire of the vial, playing with his legs against both, in a very entertaining manner, appearing perfectly alive to the persons unacquainted. He will continue this motion an hour or more in dry weather. We electrify, upon wax in the dark, a book that has a double line of gold round upon the covers, and then apply a knuckle to the gilding; the fire appears everywhere upon the gold like a flash of lightning; not upon the leather, nor if you touch the leather instead of the gold. We rub our tubes with buckskin and observe always to keep the same side to the tube and never to sully the tube by handling; thus they work readily and easily without the least fatigue, especially if kept in tight pasteboard cases lined with flannel, and sitting close to the tube. This I mention because the European papers on electricity frequently speak of rubbing the tubes as a fatiguing exer
