The completion of this Work affords me the opportunity I have long desired
of thanking your Lordship thus publicly, for the kindness with which you
acceded to my request to be permitted to dedicate it to you.

The encouragement your Lordship was pleased to give me has served to
stimulate me in the prosecution of a task, which would, I fear, have been
too great for me to have accomplished in my present condition, under any
ordinary views of ambition. Indeed, labouring as I have been for many
months past, under an almost total deprivation of sight, (the effect of
exposure and anxiety of mind in the prosecution of geographical
researches,) I owe it to the casual assistance of some of my friends, that
I am at length enabled to lay these results before your Lordship and the
public.

While I 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 Lordship 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.
