M. Antoine D’Abbadie, even previously, had _discovered_ the sources of the White Nile,—as he wrote in a letter, dated 17th October, 1844, from Adoa (Adwa), in Habesh, addressed to us in Kàhira. (Preussiche Zeitung, 21st February, 1845, and others.) That glorious fountain-head was said to lie _then_ in the land of Gmura, or Gamru, near the mountains of Bochi, or Dochi. The latitude and longitude of it were not given. He does not seem to have planted the _drapeau tricolore_ there, any more than my French companions did at the final point of our expedition; because, had they done so, both the Turks and myself would have set up our national standard. For my part I did not let the opportunity slip of denying the claims of D’Abbadie to raise a shout of victory at having solved the question of the sources of the Nile, and to contradict his absurd etymology of the Mountains of the Moon, upon which the whole discovery was said to be based. (Monthly Report of the Geographical Society in Berlin, 7th Annual Vol., p. 20.) He thought that the name of “Gmura,” or “Gamru,” being analogous in sound to that of the Arabic language, had induced the Arabian Geographers to adopt this word, and to form it into the present Kamar (Moon). Mr. Ayrton, to whom I will afterwards advert, takes the opposite side, and is of opinion that the former denomination is a corruption of the Arabic word “Kamar.” This Nile source of 1844 appears, however, to have been dried up again, or discarded by M. D’Abbadie, for he suddenly transplanted the _true sources_ of the White Stream into another country; the forest of Babia, between Inarya (Enarea,) and Jumma Kaka (Djimma Kaka); and, _to be sure_,—between 7° 49′ N. Lat., and 34° 48′ E. Long., from Paris. (See his reports and letters of 1847). I must, however, entirely controvert this second discovery, notwithstanding it is declared in the most positive manner. Error, indeed, is natural to man, but truth must assert its claims; besides, I do not deny that M. Antoine D’Abbadie would have liked to have made such a discovery, or to become an historical discoverer. Far be it from me, who know what travelling is in Africa,—who suffered the tortures of its deserts and its scorching heat, and struggled several times with fever and death, to consider the Tricolour which he fastened to the trees of the Babia forest as a vane or weathercock. No: I greet it rather with friendly interest as a cheerful sign to science and a way-mark to geographical progress, and as an agreeable surprise to succeeding travellers.
