time describes a larger, and more distant, source, to proceed from the S\V; 
answering to the White river. His Coloe lake, is clearly the Tzana of Bruce : 
and may possibly have been meant to express Galla, the name of the south- 
ern division of Abyssinia.* 
Having completed this part of the subject, I proceed to the inland posi- 
tions in the western and central parts of the continent. 
M. D'Anville has been followed in the geography of Barbary and Mo- 
rocco, with the exception of an adjustment of the interior of the latter, to 
the coasts : which are drawn from the charts in the atlas of Don Torino, in 
which the capes of Cantin, Geer, Sec. are placed more to the east, in respect 
of the strait, than in D'Anville. 
The lower parts of the Senegal, Gambia, and Rio Grande, are from M. 
D'Anville's, and Dr. Wadstrom's maps. 
Of Mr. Park's route and discoveries, it is needless to say more, than that 
the particular map which contains them, has been copied into this; forming 
a most important member of it. 
The routes and positions formerly introduced from materials collected by 
the African Association, in the northern part of the continent, are revised 
and reconstructed; perhaps with more effect, as our knowledge and expe- 
rience of the subject increases. 
Fezzan is placed, as before, due south from Mesurata : its capital Mour- 
zouk, being journies of the caravan, distant. Edrisi affords a slight 
check to the bearing, as well as to the distance, by means of Wadan, which 
lies nearly midway, and is five journies west of Sort, a known position on 
the coast : and also eight journies of his scale from Zuela, a known position 
in Fezzan. f. 
* Mr. Bruce has fallen into an error, which may mislead those who do not attend to 
his map. He says, Vol. iii. p. 720, that " the ground declines southward from the pa- 
rallel of five degrees north:" but in the map at the end of Vol. v. the waters, as we have 
just said, begin to flow southward, from the latitude of 8° north. I believe, with him, that 
farther to the west, the southern slope may not begin short of the 5th degree of latitude. 
f The day's journey of Edrisi is taken at 18 Arabic miles, or about 19 G. in direct 
distance. Strictly speaking, it should be 19,06, as Arabic miles are equal to a 
degree.
