Two more great discoveries, galvanism and electro-magnetic induction, were necessary before the practical motor became possible.
The sober Gordon had a taste for the spectacular almost equal to that of Bose.

It was he who ignited a bowl of alcohol by turning a stream of electrified water upon it, thus presenting the seeming paradox of fire produced by a stream of water.

Gordon also demonstrated the power of the electrical discharge by killing small birds and animals at a distance of two hundred ells, the electricity being conveyed that distance through small wires.
THE LEYDEN JAR DISCOVERED As yet no one had discovered that electricity could be stored, or generated in any way other than by some friction device.

But very soon two experimenters, Dean von Kleist, of Camin, Pomerania, and Pieter van Musschenbroek, the famous teacher of Leyden, apparently independently, made the discovery of what has been known ever since as the Leyden jar.

And although Musschenbroek is sometimes credited with being the discoverer, there can be no doubt that Von Kleist's discovery antedated his by a few months at least.
Von Kleist found that by a device made of a narrow-necked bottle containing alcohol or mercury, into which an iron nail was inserted, he was able to retain the charge of electricity, after electrifying this apparatus with the frictional machine.
