PEEFACE. 



Galton, F.R.G.S. The outline of Africa, the work of Mr. 

 Weller, F.R.G.S., contains the latest and the best infor- 

 mation concerning the half- explored interior of the 

 Continent. The route-map has been borrowed by 

 permission from the laborious and conscientious com- 

 pilation of Mr. Findlay, F.R.G.S., accompanying the 

 paper forwarded by me to the Royal Geographical 

 Society. The latter gentleman has also kindly supplied 

 a profile of the country traversed, showing the Eastern 

 limits of the Great Depression, and the "elevated-trough 

 formation" of Central Africa. 



In conclusion, I would solicit forbearance in all that 

 concerns certain errors of omission and commission 

 scattered through these pages. The migratory instinct 

 is now hurrying me towards the New World : I have, 

 therefore, been obliged to content myself with a single 

 revise.
