But the great source of my intelligence was the celebrated old blind Marquise du Deffand, who had a strong and lasting friendship for me. As she hated politics, she entered into none, but being the intimate friend of the Duchesse de Choiseul, who called her “granddaughter” (Madame du Deffand having had a grandmother Duchesse de Choiseul), of the Prince of Beauvau and of Madame de Mirepoix, I saw them all by turns at their house, heard their intrigues, and from her: and on two of my journeys I generally supped five nights in a week with her at the Duchesse de Choiseul’s, whither the Duke often came--and in those, and in the private parties at Madame du Deffand’s I heard such extraordinary conversations as I should not have heard if I had not been so very circumspect, as they all knew. I shall mention some instances hereafter. Here are two. Madame de Mirepoix soon grew not content with Madame du Barry. I was one evening very late on the Boulevard with Mesdames du Mirepoix and Du Deffand. The latter asked the former, “Que deviendroit Madame du Barry, si le Roi venoit à mourir?” “Que deviendroit elle?” replied she, with the utmost scorn; “elle iroit à la Salpetrière, et elle est très faite pour y aller.” On the death of Louis the Fifteenth Madame de Mirepoix was disgraced; on which her brother, the Prince de Beauvau, in compassion, was reconciled to her, and she and the Princess pretended to be reconciled, and always kissed when they met. I saw them and their niece, the Viscomtesse de Cambis, act three of Molière’s plays two nights together, to divert Madame du Deffand, who was ill. This was in 1775. Yet when I went to take leave of Madame de Mirepoix, she opened her heart to me, and showed me how heartily she still hated her sister-in-law. [17] He died in 1769. He was a virtuous man, and a great mathematician--qualities equally uncommon in a courtier of the days of Louis the Fifteenth.--E. [18] The Comte du Châtelet told me that the Duc de Choiseul having learnt from Madame de Pompadour that she intended the disgrace of the Cardinal, and the Duke for his successor, and observing that the Cardinal had no apprehension of his approaching fall, was so generous as to give him warning of it. [19] See, however, vol. iii. p. 367, note.--E. [20] This indifference to the public credit was a fatal error in the reforms of the Abbé Terray, and alone sufficed to prove his ignorance of the elementary principles of finance. He is represented to have been morose, disagreeable, and dissolute. His dismissal from office was one of the earliest and certainly most popular acts of Louis the Sixteenth.--E. [21] The Princesse de Lamballe had married the eldest son of the Duc de Penthièvre. She perished in the Revolution. Her Memoirs, an agreeable if not a perfectly authentic work, were published in 1826.--E.
