Gentlemen,
Permit me to lay before you, the humble narrative of a journey, chiefly undertaken for the investigation of the natural history of a region hitherto unexplored. Excuse the imperfect performance of the gratifying task which your liberality had imposed, but which was rendered almost abortive by the visitations of affliction.
If, in so tiresome a volume of desultory remarks, you should meet with some momentary gratification, some transient amusement, or ray of information, the author will receive the satisfaction of not having laboured entirely in vain.
