The duke listened with extreme attention to the recital of my interview in the grove surrounding the Baths of Apollo, as well as to the account of the discourse I had held there with the strange female. I endeavoured to relate the conversation as minutely and accurately as possible, but still the duke sought further particulars. He inquired the style of countenance, dress, manner, and tone of voice possessed by the _incognita_. One might have supposed, by the closeness of his questions, that he already fancied he had identified this mysterious personage: he then examined the box, which stood on the table, and remarked, “This is a very serious affair, nor can I undertake the management of it alone; it involves a too great responsibility. Spite of the lady’s assertions, I am confident the fullest confidence might be placed in all the ministers. However, I will first have a conference with M. de Saint-Florentin and the chancellor, in whose presence I will send for the lieutenant of police; and the contents of these bottles shall be immediately analyzed.” The duke, without quitting me, wrote immediately to his two colleagues as well as to M. de Sartines, requesting this latter to repair to my apartment without delay. One of the ministers summoned by M. d’Aiguillon was not at that moment at Versailles, having left at an early hour in the morning for Paris. Neither he nor M. de Sartines could possibly be with us before eight o’clock in the evening; it was therefore agreed to adjourn our conference till their arrival. Meanwhile M. d’Aiguillon, the maréchale, and myself, remained in a state of the most cruel anxiety. The duke first blamed me for not having caused the woman to be arrested, and afterwards he confessed to the maréchale, that perhaps it was better the conspiracy should be allowed time to ripen into maturity. Daring this time the liquid contained in the four bottles was being decomposed: M. Quesnay, first physician, Messrs. Thiebault and Varennes, visiting physicians, M. de la Martinière, counsellor of state, surgeon to his majesty, as well as Messrs. Ducor and Prost, apothecaries to his majesty, had been collected together for this purpose by the duc d’Aiguillon. These gentlemen came to report the termination of their experiments at the very moment when the chancellor and lieutenant of police entered the room; the duc de la Vrillière had preceded them by about five minutes; the duc d’Aiguillon requested these gentlemen to be seated. The doctors Quesnay and la Martinière were introduced, and desired to make known the result of their operations. My newly-arrived guests, who as yet understood nothing of what was going on, were struck with astonishment at hearing it said, that the four bottles of orange-flower water contained a considerable proportion of a most active poison, of which a few drops would be sufficient to cause instantaneous death. Having thus executed their commission, the medical gentlemen bowed and retired.
