Then it happened one day that Galvani, 'tired out with fruitless watching', took hold of one of the brass hooks by which the specimens were hung, and pressed it more strongly than usual against the iron railing. Immediately a twitching took place. 'I was almost at the point of ascribing the occurrence to atmospheric electricity, Galvani tells us.
To smile, to reject everything beforehand and to pass by with averted head, as was done, I remember, in the time of Galvani, and in the early days of hypnotism, is much more easy and seems more respectable and prudent than to stop, admit and examine.
From the kick of a frog's hind leg to the amazing triumphs which began with that seemingly trivial incident is a long, a very long stride if Madam Galvani had not been in delicate health, which was the occasion of her having some frog-broth prepared for her, the world of to-day might not be in possession of the electric telegraph and the light which blazes like the sun at high noon.
I thank Locke, and Hume, and Bacon, and Shakespeare, and Kant, and Fichte, and Liebnitz, and Goethe. I thank Fulton, and Watts, and Volta, and Galvani, and Franklin, and Morse, who made lightning the messenger of man. I thank Humboldt, the Shakespeare of science. I thank Crompton and Arkwright, from whose brains leaped the looms and spindles that clothe the world.
In the course of his investigations he carried them on for a long time Galvani was astonished to observe that some of his specimens, which he had hung on to an iron railing by means of brass hooks, sometimes fell to twitching even when the sky was quite clear and there was no sign of thunder.
He visited Vienna, and there heard of the discoveries of Galvani, with which he made himself familiar; went to Italy and Switzerland, where he became acquainted with the then celebrated Professors Jurine and Pictet, and with the illustrious Scarpa. He also went to Jena, formed an intimate acquaintance with Schiller and Goethe, and also with Loder, with whom he studied anatomy.
Investigators are generally quiet, unimpressive men, rather diffident, and wholly wanting in the art of interesting the public in their work. It is safe to say that neither Lavoisier, Galvani, Ohm, Regnault, nor Maxwell could have gotten the smallest appropriation through Congress to help make discoveries which are now the pride of our century.
Franklin's important discoveries are outlined in the first chapter of this book. He found out, as we have seen, that electricity and lightning are one and the same, and in the lightning rod he made the first practical application of electricity. Afterwards Cavendish of England, Coulomb of France, Galvani of Italy, all brought new bricks to the pile.
These advantages were soon made apparent by the practical application of the electric current in several fields. It will be recalled that despite the energetic endeavors of such philosophers as Watson, Franklin, Galvani, and many others, the field of practical application of electricity was very limited at the close of the eighteenth century.
These Italians could build Giotto's campanile; could paint the Transfiguration; could carve the living marble on the tombs of the Medici; could produce the Vita Nuova; could beget Galileo, Galvani, Beccaria; but still they were Foreigners.
