RC (DLC: Madison Papers); addressed: “Mr Jefferson.” On the cover is a note by Madison: “Mr. Jefferson informed me when he put this into my hands that he should not deliver the letter to Mr. B. Vaughan untill a peace shall be finally concluded; as he understood that he is a Secy to one of the British Ministers. J Madison Jr. Philada. Jany. 25th. 1783.”
Vaughan was actually a representative of his friend Lord Shelburne at the peace negotiations; he and Franklin, despite the great disparity in their ages, were warm friends. Vaughan in 1779 had brought out the only edition of Franklin’s works to appear during his lifetime, and he was connected by marriage with Henry Laurens. It is not known how or when Rush met him; Vaughan, like Rush, studied medicine in Edinburgh, but many years after Rush had been there.
