Voltaire asks that Prault follows his instructions exactly, and adds that Mr Woodman of London should be informed that the book will only sell if it is corrected. Voltaire then discusses various writings sent to him by Prault, asking that he not be listed as the author of three epistles that have been attributed to him, and insisting that Mr de la Roque and Mr Abbé Provost are employed as publishers. He then asks for a copies of various works, adding that Émilie du Châtelet would send her own list of requests in due course. Voltaire ends by discussing an erronous correction he had made to his Eléments de la philosophie de Newton, and asks that this be retracted.
