In an affair that occurred at the same time, and caused a great stir in London, d’Eon played a more active part, which, thanks to his great ability, obtained for him the approbation of the two courts and of the whole of English society. At this time the Liberal party, which had been increasing from day to day under the leadership of Wilkes, made a last effort to overthrow the cabinet. Dr. Musgrave, one of the leaders of the party, had just issued a virulent _Address to the Gentlemen, Clergy, and Freeholders of the County of Devon_. In this document he renewed the insinuations against which d’Eon had already protested in the papers as early as the year 1764, and which represented that the Princess of Wales, Lord Bute, the Duke of Richmond, Lord Egremont, and Lord Halifax had received money from France at the time of the conclusion of the treaties. Dr. Musgrave further stated that he was prepared to support his charge by fresh evidence, which he had obtained during a recent stay in Paris, and asserted that the overtures had been made through the medium of the Chevalier d’Eon, in whose possession the papers relating to that affair had assuredly remained. Finally, in a direct attack on Lord Halifax, he reproached him for having refused from personal motives to prosecute a public inquiry with regard to d’Eon’s papers, or to examine the Chevalier himself. He invited that nobleman to justify his acts before Parliament. The Secretary of State did not hesitate to accept Dr. Musgrave’s challenge, and triumphantly refuted his accusations in an eloquent speech. Parliament declared them to be groundless, and severely reprimanded the orator who had formulated them. D’Eon, besides, contributed in some measure to Lord Halifax’s success, protesting before the debate against the pamphlet by “depositions and publications.” At an early stage of the affair he addressed the following letter to Dr. Musgrave, which was reproduced by the periodicals of the day:
