An elderly valet de chambre, who was waiting for me, immediately went to give notice of my arrival, and five minutes after the charming princess made her appearance. After addressing me in a very complimentary manner, she drew all my answers from her pocket, and enquired whether I had any pressing engagements.
"Your highness may be certain that I shall never have any more important business than to attend to your wishes."
"Very well; I do not intend to go out, and we can work."
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 shin. 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."
And she shewed him the answer she had obtained herself. The count could not believe it.
"Well," said the duchess to me, "we must convince him. What shall I
ask?"
"Anything your highness chooses."
She considered for one instant, and, drawing from her pocket a small ivory box, she wrote, "Tell me why this pomatum has no longer any effect"
She formed the pyramid, the columns, and the key, as I had taught her, and as she was ready to get the answer, I told her how to make the additions and subtractions which seem to come from the numbers, but which in reality are only arbitrary; then I told her to interpret the numbers in letters, and I left the room under some pretext. I
came back when I thought that she had completed her translation, and I found her wrapped in amazement.
"Ah, sir!" she exclaimed, "what an answer!"
"Perhaps it is not the right one; but that will sometimes happen, madam."
"Not the right one, sir? It is divine! Here it is: That pomatum has no effect upon the skin of a woman who has been a mother."
"I do not see anything extraordinary in that answer, madam."
"Very likely, sir, but it is because you do not know that the pomatum in question was given to me five years ago by the Abbe de Brosses; it cured me at that time, but it was ten months before the birth of the Duke de Montpensier. I would give anything in the world to be thoroughly acquainted with that sublime cabalistic science."
"What!" said the count, "is it the pomatum the history of which I
know?"
"Precisely."
"It is astonishing."
"I wish to ask one more question concerning a woman the name of whom I would rather not give."
"Say the woman whom I have in my thoughts."
She then asked this question: "What disease is that woman suffering from?" She made the calculation, and the answer which I made her bring forth was this: "She wants to deceive her husband." This time the duchess fairly screamed with astonishment.
It was getting very late, and I was preparing to take leave, when M.
de Melfort, who was speaking to her highness, told me that we might go together. When we were out, he told me that the cabalistic answer concerning the pomatum was truly wonderful. This was the history of it:
"The duchess, pretty as you see her now, had her face so fearfully covered with pimples that the duke, thoroughly disgusted, had not the courage to come near her to enjoy his rights as a husband, and the poor princess was pining with useless longing to become a mother.
