Voltaire begins by discussing the work of Alexis Clairaut in the context of Leibniz, Émilie du Châtelet, and Sir Isaac Newton. He concludes by mentioning his prior corresponsance with Clairaut [D8455]. The copyist states that the recipient of the letter is ‘Mr. de Varennes, Receveur des Tailles de Montargin’. Besterman, however, instead notes that the recipient is Philibert Charles Marie Varenne de Fénille.
