the same state as when it was formed by its Maker. With respect to the
narrative of those expeditions, the sole merit which he claims is that of
having faithfully described what he attentively observed; neither his
pencil nor his pen has been allowed to pass the bounds of truth. There is
however one branch of his subject on which justice and gratitude render
it necessary for him to say something more. In those departments of
natural history, to which he owns himself a stranger, he has received
assistance of the utmost value from several distinguished persons. To the
few plants which, after his unfortunate fellow traveller had sacrificed
his life to the pursuit, the writer was able to collect, a permanent
place in the botanic system has been given by Dr. Lindley. Much
importance has been added to the work, by the researches and discoveries
which Professor Owen has made, with regard to the fossil remains; and the
few particulars gleaned relative to existing animals have enabled Mr.
Ogilby to introduce several interesting novelties to the attention of
zoologists. To these gentlemen, and also to Professor Faraday, Mr.
MacLeay, and other scientific friends, the warmest acknowledgments of the
writer are due, for whatever naturalists may deem worthy of praise in
these pages.

The aid thus liberally afforded, acting in unison with a feeling that, as
the surveys were undertaken by order of Government, it is his duty to lay
the result of them early before the public, has encouraged the author to
persevere steadily in bringing out these volumes; though he must candidly
own that, but for these considerations, he would rather have delayed the
performance of this task till he had completed another,* of a national
character, which, connected as it is with the days of his early service
in the cause of his country, may naturally be supposed to have stronger
and more attractive claims upon him.
