But iq the notices respecting the western course of a river, or rivers, 
from the confines of Nubia, Bornou, Sec. I think I perceive abundant 
reason for beHef, that such a course of waters does really exist ; although 
perhaps, not exactly in the mode described.* There are notices of a con- 
siderable river in Bornou (or Kanemj called the Wad-al-Gazel, or River of 
the Antelopes, said to join the Nile during the time of the inundations :t 
of another at Kuku, more to the north, said to take its course southward^ 
to the Nile.J; Also, of a Nile near Angimi and Kauga, before spoken of. 
And finally, Edrisi $ says, that a branch of the Egyptian Nile, issuing from 
the great lake at Tumi, in the south, forms the head of the Niger, or Nile 
of the Negroes. 11 
Here it is well worth remarking, that Ptolemy describes a branch spring- 
ing from the SE about the parallel of 10°, and amongst the Nubi, which 
branch flows into the Gir, a river distinct from the Niger, and appearing to 
answer to the river of Bornou, &c. This accords exacdy with Edrisi's idea; 
only that it does not flow from the same lake as the Nile, separated from it 
only by a mountain. But M. D'Anville, in my idea, interprets very fairly 
the scope of the intelligence furnished by Edrisi, by supposing that the 
sources of the two rivers (or the courses of them) were separated only by a 
ridge of mountains.** 
Leo says, that the head of the Niger is within 120 miles of the country of 
Bornou, and in the Desert of Seu : ft but these notices must be regarded as 
extremely vague. 
Certain it is, that if the eastern waters Nigritia do not run into the 
• I am aware that Mr. Beaufoy was told that the river of Bornou runs to the NW, 
into the Desert of Bilma. [Af. Assoc. p. 142 : O, 215.]

II It appears that a report of the same kind was communicated to Mr. Beaufoy; 
namely, that a branch of the Egyptian Nile runs into the Desert of Bilma. (Af. Assoc. 
Q. p. 138: O. p. 209.) There does not, however, appear to be any foundation for be- 
lieving that the Nile sends forth any branch above Egypt. All the notices of this kind 
may with more probability, be referred to a communication with the waters of Kauga.
