During the Chevalier's residence in London, suspicions arose in the minds of several persons that D'Eon was a disguised woman. The notion soon reached the Continent; and both in England and abroad, some very extraordinary wagers were made on the subject. In July, 1777, a trial took place before Lord Chief Justice Mansfield on an action brought by a Mr. Hayes against a Mr. Jacques, the latter of whom had received several premiums of fifteen guineas, to return one hundred whenever it should be proved, beyond a doubt, that the Chevalier D'Eon was a woman. MM. Louis Legoux and de Morande deposed to this as a fact so thoroughly established, that the defendant's counsel actually pleaded that the wager was unfair, because the plaintiff knew, before it was laid, that the Court of France had treated with the Chevalier as a woman. The plaintiff, however, obtained a verdict, which was afterwards set aside on the ground of the bet being illegal. Shortly after the conclusion of the trial, the Chevalier d'Eon, for some unaccountable reason, put on female attire, which he contrived to wear until his death. Everybody now believed that D'Eon was a woman. Several portraits were published representing him in various characters--as an officer of dragoons, as a French minister, as a fashionable lady, etc. Mr. Hooper, of Ludgate-hill, published a mezzotinto engraving of the Chevalier as Pallas, a casque on her head, a lance in her right hand, and the ægis on her left arm. Round the edge of the shield were the words _At nunc dura dedit vobis discrimina Pallas_. On each side were drums, muskets, pyramids of cannon-balls, heavy pieces of ordnance, and a pair of colours on which were written, _Impavidam serient ruinæ_. In the middle distance might be seen a citadel and a camp. The lower part of the engraving contained representations of the principal events of the Chevalier's life, with a eulogy, in English, on his talents and virtues. After rapturously praising the genius, the courage, the personal beauty of D'Eon, this eulogy concludes by saying that "her military comrades offer this homage as an eternal monument of their affection." The breaking out of the French Revolution deprived D'Eon of his pension. He returned to France in 1792 and offered his services to the National Assembly. But they were declined; and on his return to England his name was placed on the list of Emigrants. He was now plunged into the depths of poverty, and supported himself as best he could by giving lessons in fencing. But he depended chiefly on the kindness of Elisée, first surgeon to Louis XVIII., and other friends. He died May the 21st, 1810, when Elisée assisted in the dissection of his body; and declared that the Chevalier belonged to the male sex. * * * * *
