She then shewed me all the questions which she had already prepared on different subjects, and particularly those relating to the cure of her pimples. One circumstance had contributed to render my oracle precious to her, because nobody could possibly know it, and I had guessed it. Had I not done so, I daresay it would have been all the same. I had laboured myself under the same disease, and I was enough of a physician to be aware that to attempt the cure of a cutaneous disease by active remedies might kill the patient.
I had already answered that she could not get rid of the pimples on her face in less than a week, but that a year of diet would be necessary to effect a radical cure.
We spent three hours in ascertaining what she was to do, and, believing implicitly in the power and in the science of the oracle, she undertook to follow faithfully everything ordered. Within one week all the ugly pimples had entirely disappeared.
I took care to purge her slightly; I prescribed every day what she was to eat, and forbade the use of all cosmetics; I only advised her to wash herself morning and evening with plantain water. The modest oracle told the princess to make use of the same water for her ablutions of every part of her body where she desired to obtain the same result, and she obeyed the prescription religiously.
I went to the opera on purpose on the day when the duchess shewed herself there with a smooth and rosy skin. After the opera, she took a walk in the great alley of the Palais-Royal, followed by the ladies of her suite and flattered by everybody. She saw me, and honoured me with a smile. I was truly happy. Camille, Madame de Polignac, and M. de Melfort were the only persons who knew that I was the oracle of the duchess, and I enjoyed my success. But the next day a few pimples reappeared on her beautiful complexion, and I received an order to repair at once to the Palais-Royal.
The valet, who did not know me, shewed me into a delightful boudoir near a closet in which there was a bath. The duchess came in; she looked sad, for she had several small pimples on the forehead and the chin. She held in her hand a question for the oracle, and as it was only a short one I thought it would give her the pleasure of finding the answer by herself. The numbers translated by the princess reproached her with having transgressed the regimen prescribed; she confessed to having drunk some liquors and eaten some ham; but she was astounded at having found that answer herself, and she could not understand how such an answer could result from an agglomeration of numbers. At that moment, one of her women came in to whisper a few words to her; she told her to wait outside, and turning towards me, she said,
“Have you any objection to seeing one of your friends who is as delicate as discreet?”
With these words, she hastily concealed in her pocket all the papers which did not relate to her disease; then she called out.
A man entered the room, whom I took for a stableboy; it was M. de Melfort.
“See,” said the princess to him, “M. Casanova has taught me the cabalistic science.”
