The Dauphin had good sense, but he suffered his wife to govern him; he loved only such persons as she loved, and he hated all who were disagreeable to her.  It was for this reason that Nangia enjoyed so much of his favour, that he, with all his sense, became so perfectly ridiculous.

The Dauphine of Burgundy was the person whom the King loved above all others, and whom Maintenon had taught to do whatever was agreeable to him.  Her natural wit made her soon learn and practise everything.  The King was inconsolable for her death; and when La Maintenon saw that all she could say had no effect upon his grief, it is said that she told the King all that she had before concealed with respect to the Dauphine’s life, and by this means dissipated his great affliction.

[This young lady, so fascinating and so dear to the King, betrayed, nevertheless, the secrets of the State by informing her father, then Duke of Savoy, and our enemy, of all the military projects which she found means to read.  The King had the proofs of this by the letters which were found in the Princess’s writing case after her death.  “That little slut,” said he to Madame Maintenon, “has deceived us.”  Memoires de Duclos, tome i.]

Three years before her death, however, the Dauphine changed greatly for the better; she played no more foolish tricks, and left off drinking to excess.  Instead of that untameable manner which she had before, she became polite and sensible, kept up her dignity, and did not permit the younger ladies to be too familiar with her, by dipping their fingers into her dish, rolling upon the bed, and other similar elegancies.  She used to converse with people, and could talk very well.  It was the marriage of Madame de Berri that effected this surprising change in the Dauphine.  Seeing that young lady did not make herself beloved, and began things in the wrong way, she was desirous to make herself more liked and esteemed than she was.  She therefore changed her behaviour entirely; she became reserved and reasonable, and, having sense enough to discover her defects, she set about correcting them, in which she succeeded so as to excite general surprise.  Thus she continued until her death, and often expressed regret that she had led so irregular a life.  She used to excuse herself by saying it was mere childishness, and that she had little to thank those young ladies for who had given her such bad advice and set her such bad examples.  She publicly manifested her contempt for them, and prevailed on the King not to invite them to Marly in future.  By this conduct she gained everybody’s affection.

She was delicate and of rather a weak constitution.  Dr. Chirac said in her last illness that she would recover; and so she probably would have done if they had not permitted her to get up when the measles had broken out upon her, and she was in a copious perspiration.  Had they not blooded her in the foot she might have been alive now (1716).  Immediately after the bleeding, her skin, before as red as fire, changed to the paleness of death, and she became very ill.  When they were lifting her out of bed I told them it was better to let the perspiration subside before they blooded her.  Chirac and Fagon, however, were obstinate and laughed at me.
