“He could scarcely pass a gold leaf electrometer without causing the leaves to diverge by a sudden flick from his silk handkerchief. I recollect, too, his meeting me at the entrance to the lecture theatre at Jermyn Street, when Lyon Playfair was giving the first, or one of the first lectures ever delivered in the building. ‘Let us go up here,’ said he, leading me far away from the central table. I asked him why he chose such an out-of-the-way place. ‘Oh,’ he replied, ‘we shall be able here to find out what are the acoustic qualities of the room.’ “The simplicity of the means with which he made his experiments was often astonishing, and was indeed one of the manifestations of his genius. A good instance is thus narrated by Sir Frederick Arrow:--‘When the electric light was first permanently exhibited at Dungeness, on 6th June, 1862, a committee of the Elder Brethren, of which I was one, accompanied Faraday to observe it. Before we left Dover, Faraday showed me a little common paper box and said, “I must take care of this; it’s my special photometer,”--and then, opening it, produced a lady’s ordinary black shawl pin (jet, or imitation, perhaps)--and then holding it a little way off the candle, showed me the image very distinct; and then, putting it a little further off, placed another candle near it, and the relative distance was shown by the size of the image.’ “In lecturing to the young he delighted to show how easily apparatus might be extemporized. Thus, in order to construct an electrical machine, he once inverted a four-legged stool to serve for the stand, and took a white glass bottle for the cylinder. A cork was fastened into the mouth of this bottle, and a bung was fastened with sealing wax to the other end: into the cork was inserted a handle for rotating the bottle, and in the centre of the bung was a wooden pivot on which it turned: while with some stout wire he made crutches on two of the legs of the stool for the axles of this glass cylinder to work upon. The silk rubber he held in his hand. A japanned tea cannister resting on a glass tumbler formed the conductor, and the collector was the head of a toasting fork. With this apparently rough apparatus he exhibited all the rudimentary experiments in electricity to a large audience.” Faraday’s Orderliness and Imagination. Faraday, in addition to the rarest ability in experiment, had an orderliness of mind which gave the utmost effectiveness to his work in every department. His successor, Professor John Tyndall, says:--
