Frederick the Great, as an Author, Soldier, King and Man, well deserves to have his History written; better perhaps than Charles XII, whose Biography by Voltaire has always seemed to me one of the most delightful Books. Let your Publishers offer me Three hundred pounds, and time to heat the historico-biographical crucible and fill it and fuse it properly, and I will give them the best single Volume I can on the brave Fritz: I think it might be ready before this time twelvemonth; and very probably I might go to Germany in winter to inquire into it better. This is the most eligible enterprise I can think of at present: if you can arrange your side of it on these terms, I shall be very happy to hear so, as soon as possible, and proceed forthwith to take measures for performing mine.
