The comfort and hope which were just appearing in the midst of so many troubles vanished suddenly like lightning; the dauphiness fell ill on the 5th of February; she had a burning fever, and suffered from violent pains in the head; it was believed to be scarlet-fever (rougeole), with whispers, at the same time, of ugly symptoms; the malady went on increasing; the dauphin was attacked in his turn; sacraments were mentioned; the princess, taken by surprise, hesitated without daring to speak.

Her Jesuit confessor, Father La Rue, himself proposed to go and fetch another priest.

A _Recollet_ (Raptionist) was brought; when he arrived she was dying.

A few hours later she expired, at the age of twenty-six, on the 12th of February, 1712.

"With her there was a total eclipse of joys, pleasures, amusements even, and every sort of grace; darkness covered the whole face of the court; she was the soul of it all, she filled it all, she pervaded all the interior of it." The king loved her as much as he was capable of loving; she amused him and charmed him in the sombre moments of his life; he, like the dauphin, had always been ignorant of the giddiness of which she had been guilty; Madame de Maintenon, who knew of them, and who held them as a rod over her, was only concerned to keep them secret; all the court, with the exception of a few perfidious intriguers, made common cause to serve her and please her.
