The doctor and his devoted Joe remained the same men that we have known them, excepting that one change took place at their own suggestion. They ceased to be master and servant, in order to become bosom friends. The journals of all Europe were untiring in their praises of the bold explorers, and the _Daily Telegraph_ struck off an edition of three hundred and seventy-seven thousand copies on the day when it published a sketch of the trip. Doctor Ferguson, at a public meeting of the Royal Geographical Society, gave a recital of his journey through the air, and obtained for himself and his companions the golden medal set apart to reward the most remarkable exploring expedition of the year 1862. 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.
