[Footnote 1: This is the map which was published by Mr. Petermann, in the account of the progress of the Expedition to Central Africa, adding from Mr. Richardson’s and Mr. Overweg’s journals, which I had sent home, an outline of those districts visited by themselves alone.] [Footnote 2: See Vol. II. p. 272.] [Footnote 3: See Vol. II. p. 276.] [Footnote 4: See Vol. III. p. 348, note.] [Footnote 5: The depth of the well measured twenty-two fathoms.] [Footnote 6: This is a complaint to which almost every European in these climes is exposed, and from which Clapperton suffered very severely.
