eastward, seems to be meant, either for the largest of the lakes, or for the 
lakes of that country (of which there are several), collectively. It is no im- 
peachment of this opinion, that the Libya Palus is placed so far to the 
west as the meridian of Carthage, whilst the lakes of W angara appear to be 
in that of Cyrene : for Ptolemy carries the river Gir, and the capital of the 
country which represents Bornou, into the centre of Africa; by which he 
has shortened the course of the Niger, in the same proportion as he had ex- 
tended that of the Gir, or Wad-al-Gazel. Modern geographers, to the time 
of D'Anville, were guilty of the same kind of error: Ghana is about 6° too 
far west, in Delisle's map. 
It may be best to omit any farther remarks on Ptolemy, at present, and 
to wait the result of future discoveries. In the mean time, those who are 
curious to read M. D'Anville's Memoir on the subject of " the Rivers in 
the interior of Africa," will find it in the Mem. Acad. Inscrip. Vol. xxvl
