time describes a larger, and more distant, source, to proceed from the SW ; 
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 ip the western and central parts of the continent. 
M. D'Anville has been followed in the geography ofBarbary and Moroc- 
co, 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 Tofino, 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 experience 
of the subject increases. 
Fezzan is placed, as before, due south from Mesurata : its capital Mour- 
zouk, being 17^ 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 
Clearly 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.t 
• Mr. Bruce has fallen into an error, which may mislead those who do not attend to his 
m^p. He says. Vol. iii. p. 730, that *• the ground declines southward, from the parallel 
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 5 th 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 56^ Arabic miles are equal to a degree^
