Voltaire asks Michel Lambert to send him Luigi Ferdinando, conte di Marsigli’s Stato militare dell’imperio ottomano. He sends logistical instructions regarding proofs and printing and reminds Lambert that he is expecting an answer regarding a proposed joint publishing venture with the Cramer brothers of Geneva. He asks Lambert to sell the bulkier (folio and quarto) volumes that he left in Paris when leaving for Prussia in 1750. The final line (‘jattends de ses nouvelles’) and the signature (‘v’) are autograph.

Voltaire is in Senones undertaking research in the library for his universal history (Essai sur les mœurs). Villaume writes a bibliographic reference at the top of the letter, to which Voltaire appends a quote in Latin, both of which are omitted from published versions of this letter. Voltaire is asking Dupont for information relating to this reference.
