Pierre Jacques Claude Dupuits writes that his father is not writing to François Louis Claude Marin as he is unwell, and asks Marin to forward a package onto Mr Lacombe. He encloses a corrected version of Voltaire’s Épitre à Mr. de Saint Lambert, and asks that this version be included in the new book. He ends the letter by addressing the production of the first of twelve medals, one of which would have depicted Voltaire.
