Mallet du Pan writes that Mr. Chirol has informed him about Thoruneysen’s Voltaire prospectus, something he strongly encourages. He adds that such an edition would be do the Swiss press a great honour and that he is delighted that it has ended the ‘villainy’ of those from Lausanne. Mallet du Pan offers his services wherever he might be useful, adding that he spoke to Wagnière a few months ago, and that Wagnière was in possession of several short works that were not included in the Beaumarchais edition. He recommends Thoruneysen contacts Wagnière about his edition, as well as Gabriel Cramer whom he claims also has ‘valuable pieces’.

The letter begins with a poem known as ‘À monsieur le maréchal duc de Richelieu’. The verse is in Collini’s hand. The prose and date line are in Voltaire’s hand.
