On the morrow we went as usual to wait in the gallery for the breaking-up of the council, and for the King's Mass. Madame came there. Her son approached her, as he did every day, to kiss her hand. At that very moment she gave him a box on the ear, so sonorous that it was heard several steps distant. Such treatment in presence of all the Court covered with confusion this unfortunate prince, and overwhelmed the infinite number of spectators, of whom I was one, with prodigious astonishment. That day the immense dowry was declared; and on Sunday there was a grand ball, that is, a ball opened by a 'branle' which settled the order of the dancing throughout the evening. Monseigneur the Duc de Bourgogne danced on this occasion for the first time; and led off the 'branle' with Mademoiselle. I danced also for the first time at Court. My partner was Mademoiselle de Sourches, daughter of the Grand Prevot; she danced excellently. I had been that morning to wait on Madame, who could not refrain from saying, in a sharp and angry voice, that I was doubtless very glad of the promise of so many balls--that this was natural at my age; but that, for her part, she was old, and wished they were well over. A few days after, the contract of marriage was signed in the closet of the King, and in the presence of all the Court. The same day the household of the future Duchesse de Chartres was declared. The King gave her a first gentleman usher and a Dame d'Atours, until then reserved to the daughters of France, and a lady of honour, in order to carry out completely so strange a novelty. I must say something about the persons who composed this household.
