At first, the Abbé could not believe that America was capable of producing such letters, and insisted that they must have been fabricated at Paris for the purpose of discrediting his system. In fact, he even doubted whether there was such a person as Franklin, but, afterwards, being convinced upon that point, he published a volume of letters, mainly addressed to Franklin, in which he defended his own theory, and denied the accuracy of Franklin's experiments and conclusions. Le Roy, of the Royal Academy of Sciences, rejoined on behalf of Franklin, who had decided to let the truth be its own champion, and easily refuted the Abbé. The papers could not have asked for a better advertisement than this controversy. They were further translated into the Italian, German and Latin languages, and Franklin's theory of electricity was so generally adopted by the learned men of Europe, in preference to that of the Abbé, that the latter lived, Franklin tells us, to see himself the last of his sect, except Monsieur B. of Paris, his _élève_ and immediate disciple. It is surprising that even the solitary _élève_ should have been left clinging to his master; for, in the meantime, the most momentous experiment, suggested by Franklin in his letters, had been performed, substantially in the manner outlined by him, with brilliant success, by D'Alibard, on a hill at Marly-la-Ville, where a pointed rod of iron, forty feet high, and planted on an electric stand, had been erected for the purpose of carrying it into execution. When a thundercloud passed over the rod on May 10, 1752, between 2 and 3 o'clock in the afternoon, the persons, set by D'Alibard to watch it, had drawn near "and attracted from it sparks of fire, perceiving the same kind of commotions as in the common electrical experiments." A week later, the fire and crackling sound, elicited by M. de Lor from a rod, erected at his house in Paris on a cake of resin, and electrified by a cloud between 4 and 5 o'clock in the afternoon, told the same story. He had previously performed what he called the "Philadelphia experiments" in the presence of Louis XV., who seems to have been as much delighted with them as if they had been a new mistress. In a short time, they became so popular that we are told by Franklin that "all the curious of Paris flocked to see them." One of the results of the fame acquired by him in France was a letter written by Dr. Wright, an English physician, then in Paris, to a member of the Royal Society, apprising the latter of the excitement that the experiments had created in France, and expressing his astonishment that Franklin's papers had been so little noticed in England. Quickened by Dr. Wright's words, the Society reconsidered the letters which had been read before them, and caused an abstract of them and the other letters on electricity, sent to England by Franklin, to be printed among its Transactions. Afterwards, when several
