Either at the house of his friend, Barthélemy, or at the ambassador’s, with whom he always kept up the pleasant intercourse so strangely renewed after an interval of several years, d’Eon met all the distinguished Frenchmen living in London or passing through it. Among them were the Duc de Chaulnes and the Marquis du Hallay, the Prince de la Trémoille and the Marquis d’Hautefort, Prince Rezzonico, nephew of Pope Clement XIII., M. de Calonne, and the former Abbé du Bellay, vicar-general of the diocese of Tréguier. He thus kept in touch with the best French society. Never neglecting an opportunity for putting pen to paper, he kept up, besides, a most voluminous correspondence. Several of his friends also informed him regularly of what was passing in France. Thus Drouet, his old colleague in the secret service, confided to the Comtesse Potocka a letter in which, after expressing his ardent desire to see him back again in France, tells of the great scandal of the day, the trial of Cardinal de Rohan—“l’affaire du collier”: This important case has never been so much discussed as at the present moment. M. Cagliostro is making many partisans by a memorandum he has published. As many people regard him as a swindler, a charlatan, an empiric, and judge him by his conduct at Warsaw where he was staying in 1777, I went yesterday to see Count Rzewusky, who that same year was all-powerful in Poland. He told me that when Cagliostro arrived he did not conceal the fact that he had some knowledge of physics and medicine, and even of alchemy. A certain Prince Poninsky, experimenting in the latter, became very intimate with him, and having seen his wife he fell in love with her. Shortly afterwards he offered her some diamonds, which she refused. Thereupon he appealed to her husband, and succeeded, by dint of entreaties, in inducing him to allow his wife to accept the diamonds. Having failed to obtain what he desired from Madame de Cagliostro, and not wishing to be a dupe, Poninsky denounced Cagliostro as a swindler, and obtained permission to take back his diamonds which would have been returned to him had he asked for them. A few days before the arrival of Cagliostro at Warsaw the sister of Count Rzewusky, fearing lest she should lose her sight on account of an eye-complaint which completely baffled the doctors, consulted Cagliostro, who cured her entirely in the course of a few days. This lady, who is very rich, offered him two thousand ducats, which he refused. She renewed her offer through her brother, who met with no better success; and neither the one nor the other has been able to persuade Cagliostro to accept the smallest token of gratitude.
