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.
