points about which he was dubious, but has entirely 
precluded him from having the subjects considered, 
or the specimens classified and arranged by gentle- 
men of scientific acquirements in those departments 
of knowledge, in which the author is conscious he is 
himself defective. In the latter part of the Expedi- 
tion, or from Fowler’s Bay to King George’s Sound, 
the dreadful nature of the country, and the difficul- 
ties and disasters to which this led, made it quite 
impossible either to make collections of any kind, or 
to examine the country beyond the immediate line 
of route ; still it is hoped that the passing notices 
which are made in the journal, and the knowledge 
of the similarity of appearance and uniform charac- 
ter, prevalent throughout the greater portion of the 
country passed through, will be quite sufficient to 
give a general and correct impression of the whole. 
To Mr. Gray of the British Museum, the author 
is particularly indebted for his valuable contribution 
on the Natural History of the Southern coast of 
Australia, and to Mr. Gould, the celebrated Orni- 
thologist, his thanks are equally due, for a classified 
and most interesting list of the birds belonging to 
the same portion of the continent. 
To Mr. Adam White, of the British Museum, he is 
also indebted for an account of some new insects, and 
to Dr. Richardson, for a scientific and classified 
arrangement of fish caught on the Southern coast, 
near King George’s Sound. The plates to which 
the numbers refer in the last-mentioned paper, are
