The first result of Dr. Ferguson's expedition was to establish, in the most precise manner, the facts and geographical surveys reported by Messrs. Barth, Burton, Speke, and others. Thanks to the still more recent expeditions of Messrs. Speke and Grant, De Heuglin and Muntzinger, who have been ascending to the sources of the Nile, and penetrating to the centre of Africa, we shall be enabled ere long to verify, in turn, the discoveries of Dr. Ferguson in that vast region comprised between the fourteenth and thirty-third degrees of east longitude.
