Voltaire begins by saying that since he saw the new edition by Etienne Ledet he is more determined than ever to provide Prault with a copy that will be useful and honourable to him. He adds that Prault can depend on the protection of d’Argenson, and on his own zeal, noting that he would be angry if only foreigners benefitted from his works and if the Paris bookseller whom he esteems the most has only useless offers of service from him. Voltaire then discusses his essay on Molière, before asking if it is true that his epistles and the beginning of his Siècle de Louis XIV have been published. He notes that he would like to be sent copies if this is the case.
