the authors of many books and maps continued to adhere to the 
ancient notion. 
In 1T9 1, part of the veil which covered the interior of Africa 
was removed. Two Englishmen, Watt and Winterbottom, setting 
out from the banks of the Rio Nunez, proceeded as far as Timbo, 
which, it is true, is only sixty leagues distant from the coast, but 
they there acquired some new information. 
Lastly, in 1795, Mungo Park commenced the journey in which

from west to east ; after proceeding for some time along its banks,

on it, and navigating that river to its mouth ; he perished in this en- 
terprise, and increased the numerous list of generous men, who have 
sacrificed their lives to the progress of science. Part of his journal 
was fortunately preserved ; it is the more valuable for geography, as 
in this journey he was provided with instruments which enabled him 
to determine the position of places by observations ; and he rectified 
the course of the Gambia. 
Since the first journey of Mungo Park, several travellers and 
different authors have published accounts of Western Africa ; Gol- 
berry in 1802, and Durand in 1807, had visited this continent at 
the close of the last century. The Atlas annexed to the narrative 
of Durand, contains many maps which present the most recent
