The manuscript is an autograph letter, written in the hand of Philippe Antoine de Claris. It discusses the affair of Antoine Lefèbvre de La Barre which implicated M. de Belleval and M. Douville. Expressing significant concern about the allegations made against M. de Belleval, the letter also mentions the mémoires of Madame de Sauvigni, pertaining to Madame de Goeman, and reflects on the fight between M. de Beaumarchais and Bertrand. According to T. D. N. Besterman, the folios are numbered 91-92.

Voltaire writes that only his old age and languid state could have prevented him from coming to pay court to de Sauvigny and Madame de Sauvigny. He invites them to dine with himself and Marie-Louis Denis [née Mignot] [née Mignot] at their ‘hovel’ at Ferney. He adds that his is distressed to hear of Madame de Sauvigny’s indisposition and hopes that it will not have consequences serious enough to deprive him of their company for dinner. Voltaire ends by saying that he expects them tomorrow at two o’clock.
