IV 
DEDICATION. 
many months past, under an almost total depriva- 
tion of sight, (the effect of exposure and anxiety 
of mind in the prosecution of geographical re- 
searches,) I owe it to the casual assistance of some 
of my friends, that I am at length enabled to lay 
these results before your l.ordsbip and tbe public. 
While 1 feel a painful conviction that many 
errors must necessarily pervade a work produced 
under such unfavourable circumstances, it affords 
me no small consolation to reflect that your Lord- 
ship has been aware of my situation, and will be 
disposed to grant me every reasonable indulgence. 
I have the honor to be, 
With the highest respect, 
My Lord, 
Your Lordship’s 
Very obedient and humble Servant, 
CHARLES STURT. 
London, 
June, 1833.
