"In the month of June, 1776 (few among us remember it), a young man twenty-five years old, named Jouffroy, was making a trial trip on the river Doubs of a new steamboat forty feet in length and six feet in breadth. For two years he had been calling the attention of scientific authorities to his invention; for two years he had been stoutly asserting that there is a powerful latent energy in steam,--at that time a neglected asset. All ears were deaf to his words. His only reward was to be completely isolated and neglected. When he passed through the streets of Baume-les-Dames, his appearance was the signal for jests innumerable. He was dubbed 'Jouffroy, the Steam Man' ('_Jouffroy-la-Pompe_'). Ten years later, having built a pyroscaphe [literally, fireboat] which had ascended the Saone from Lyons to the island of Barbe, he presented a petition to Calonne, the comptroller-general of finance, and to the Academy of Sciences. They would not look at his invention! "On August 9, 1803, Fulton went up the Seine in a new steamboat at the rate of about four miles an hour. The members of the Academy of Sciences as well as government officials were present on the occasion. The next day they had forgotten all about it, and Fulton went to make the fortunes of Americans. "In 1791 an Italian at Bologna, named Galvani, having hung on the iron railing outside his window some skinned frogs which had been used in making a bouillon for his wife, noted that they moved automatically, although they had been killed since the evening before. The thing was incredible, so everybody to whom he told it opposed his statement. Men of sense would have thought it beneath their dignity to take the trouble to verify the story, so convinced were they of its impossibility. But Galvani had noted that the maximum of effect was attained when he joined the lumbar nerves and the ends of the feet of a frog by a metallic arc of tin and copper. The frog's muscles then jerked convulsively. He believed it was due to a nervous fluid, and so lost the fruit of his investigations. It was reserved for Volta to discover electricity.
