We found we could not get quite ready to set out to-day, so have adjourn’d our Departure till to-morrow. As Company, (I know not how many) talk of going part of the Way with us, I think it will be inconvenient to breakfast with you as proposed. We shall therefore only stop at your Door to take Leave. Herewith you have the Receipt you desired. When you write to Canton and Nairne, enclose your Letter to me, and I will write with it and forward it per the Packet. Mr. Winthrop has Aepinus, and I think a Piece also of the same Author, on the Distribution of Heat. When he has done with them he will deliver them to you. I am, Dear Sir, with great Esteem Your most obedient humble Servant,
