rarely accessible to the general reader. A 
list is annexed of the best works tending to 
illustrate the geography of this Continent, 
which, it is hoped, will be found useful to 
those who wish to make deeper researches 
into that interesting subject. 
The maps accompanying this work have 
been executed with the greatest care, and 
from the most recent and authentic mate- 
rials. The historical maps attached to the 
third book can be considered only as sketch- 
es, without any attempts at minute accu- 
racy. It is hoped, however, that they will 
be found to contain an accurate expression 
of the general ideas entertained by geo- 
graphical inquirers, at these successive pe- 
riods, of the form and constituent parts of 
the African Continent.
