Note 203 — Chapter XI
Reading edition
It should be recollected that D’Alembert’s intimacy with Mademoiselle Espinasse had caused him to quarrel with Walpole’s old friend, Madame du Deffand. He wrote much that has long ceased to be read; but his Introduction to the Encyclopédie is a very able work, and as a mathematician he was one of the most eminent of his day. He died in 1783, aged sixty-six.—E.
