Note 275 — CHILDE HAROLD'S PILGRIMAGE CANTO THE THIRD.
Reading edition
{209} [D'Alembert (Jean-le-Rond, philosopher, mathematician, and belletrist, 1717-1783) had recently lost his friend, Mlle. (Claire Françoise) L'Espinasse, who died May 23, 1776. Frederick prescribes quelque problème bien difficile à résoudre as a remedy for vain regrets (Oeuvres de Frédéric II., Roi de Prusse, 1790, xiv. 64, 65).]
