Note 9 — Chapter XVI · JOURNEY TO ÁGADES.

I trust my readers will approve of my using the expression Western Negroland to denote the countries from Fúta as far as Sókoto; Middle Sudán, or Central Negroland, from Sókoto to Bagírmi; and Eastern Negroland, comprising Wadäy, Darfúr Kordofán, and Sennár. However, here, when I say that Mohammed ben ʿAbd el Kerím introduced Islám into Central Negroland, I exclude Bórnu, where the Mohammedan religion is much older.
