Madame de Graffigny describes Émilie du Châtelet’s personality, before turning to matters concerning Voltaire. She gives her opinion on his Le Petit Boursoufle, and gives an update on Voltaire’s health. She further discusses the Abbé Desfontaines and Jean-Baptiste Rousseau, especially with reference to Voltaire. The letter is incomplete; Devaux was tasked with returning the letter to Cirey so that Madame de Graffigny could burn the first pages, which it appears that she did.

Samuel König begins by denyng that he has had any role in inciting attacks against Maupertuis, adding that Maupertuis has only himself to blame for them. He states that he has seen almost nothing in Germany which attacks Maupertuis, and has not requested that anyone produce anything to that effect. König then turns to Voltaire and Émilie Du Châtelet, saying that he did not know that they were on poor terms with Maupertuis before the publication of Voltaire’s Diatribe du docteur Akakia. He concludes with reference to Leonhard Euler and mocks his writings in defence of Maupertuis.

König begins with a discussion of his translation of the Figure de la Terre by Maupertuis which had recently been published, adding that he is surprised that the largest critique of the work should come from Maupertuis. He then mentions a letter that he had received from Voltaire in which Voltaire wrote that he had left King Solomon [Frederick II of Prussia] because he loved the Queen of Sheba [Émilie du Châtelet]. König ends the letter by critiquing Émilie du Châtelet’s Institutions de Physique which had been published in the preceding year.
