In endeavouring to exhibit a general view of the 
Natural History of Africa, it may be proper to be- 
gin with its 
Mineralogy. 
The minerals of this great continent are very 
imperfectly known, and the geognostical relations 
of its rocks have hitherto engaged the attention of 
but few observers. The facts we shall now state 
are given by travellers in the accounts of their 
journeys, but which are in general much less satis- 
factory than the present state of mineralogical 
science demands. 
* I am happy in being able to state, that I am indebted 
for this chapter to my friend Mr Jameson, the very eminent 
Professor of Natural History in the University of Edinburgh, 
and well known to the learned world by his excellent works, 
on Geology and Mineralogy.
