Johann Georg Altmann discusses his anti-Koenig sentiments, noting that he has circulated three ant-Koenig letters among distinguished individuals, and is planning on publishing further anti-Koenig material after objection to his role in the controversy surrounding the theory of least action. He goes on to say that literary disputes have been raging in Switzerland, ‘especially after M. de Voltaire has begun to meddle officiously in it, and since Koenig and his defender [i.e. Voltaire] have been so very insolent’. He concludes by providing extensive details about a dispute between Voltaire and and the magistrates in Bern.

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.
