Norris's copy has now disappeared. It was being used as late as 5 October 1832, for James Mease commented that there was a marginal note by Evans that "all great storms begin at the leeward." Somehow, this note strengthened Mease's theory that the present earth "was made at the creation from the ruins of another" (Minutes). Wheat: 672. Contains comments about the origins of the northeast storms (suggested by B. Franklin?), lightning and electricity, navigation of the Delaware River, and other bays, etc. Endorsement on back, in Benjamin Franklin's hand: "To Dr. John Mitchell from Mr. B. Franklin." The map was at one time in the collection of the Marquess of Bute, a friend of Mitchell's. Joseph Parker Norris gave a copy of this map to the American Philosophical Society on 16 June 1815.
