gitude of about six degrees only ; so that there is little question but that M. 
D'Anville's statement is wrong. 
From Sennar, Mr. Bruce has a new and interesting route, northward to 
Syene. Dongola lay wide to the west of this route; and he has not informed 
us on what authority it is placed in his map. Still, however, the change in 
the position of the Nile, must carry Dongola to the eastward with it, of 
course; and in Bruce's map it is found at i° 18' difF. long, to the east of 
D'Anville's ;* equal to 73 G. miles. The latitude of Dongola is also i a de- 
gree to the south of the parallel assigned by D'Anville, that is, igi instead of 
20°. With respect to that of Sennar, D'Anville was right. 
In describing the western head of the Nile (and which has no existence 
in Mr. Bruce's map), it may be thought that I have advanced into the regions 
of conjecture ; but I trust that I have not gone beyond the limits implied by 
the authorities. To enter into a detail of these, together with the deductions 
and combinations arising from them, would occupy too much room here ; 
especially as they are designed for another place. It may be sufficient to state, 
that the branch in question, called the White River, or ^biad^f is admitted 
by Mr, Bruce himself, to be a more bulky stream than the Abyssinian branch. 
That M. Maillet was told, that it holds a course which is distant from 12 to 
20 journies from the eastern branch. That Ledyard was told at Cairo, by 
certain persons from Darfoor, that the Nile has its fountains in their country 
situated 55 journies to the westward of Sennar and whose /row^zVr province, 
Kordofan, is placed by Bruce, adjoining to the west of the country of Sen- 
nar. And finally, that Ptolemy, Edrisi, and Abulfeda, all place the head of 
the Nile in a quarter far remote from Abyssinia. Ptolemy, in particular, has 
described the eastern source, in such a way, as that it cannot be taken for any 
other than the Abyssinian branch [i. e. Bruce's Nile) ; and yet he at the same 
• That is, M. D. places it 36 min. west of Cairo : Mr. B. 42 min. east of it. 
f This must not be confounded with the Neel Abeed, the name applied by the Arabs, 
to the Niger. 
X See Mr. Ledyard's communications in African Association, for 1790, — 91. He says 
55 journies, or four or five hundred miles. There must, of course, be an error, either in 
the number of the journies, or of the miles.
