In preparing this volume for the press, I have been under the greatest obligations to Captain P. P. King, R. N., an officer whose researches have added so much to the geography of Australia. This gentleman has not only corrected my manuscript, but has added notes, the value of which will be appreciated by all who consider the opportunities he has had of obtaining the most correct information upon these subjects, during his surveys of the coasts parallel to my track.

To S. A. Perry, Esq., Deputy Surveyor General, I am extremely indebted for the assiduous labour he has bestowed in draughting my map. I shall ever remember the friendly interest he expressed, and the courteous attention with which he listened to the details of my journey.

From the Rev. W. B. Clarke, in addition to the unvaried kindness he has evinced towards me since my arrival in Australia, I have received every assistance which his high scientific acquirements enabled him to give.

I take this opportunity of publicly expressing my most sincere thanks to these gentlemen, for the generous assistance they have afforded me on this occasion, and for the warm interest which they have been kind enough to take in the success of my approaching enterprise.

Ludwig Leichijardt. Sydney, September 29th, 1846.
