I wish it, therefore, to be understood, that unless mention is made of other tribes, or other parts of the continent, the details given are intended to apply to that province generally, and particularly to the tribes in it, belonging to the districts of Adelaide and the Murray river.
As far as has yet been ascertained, the whole of the aboriginal inhabitants of this continent, scattered as they are over an immense extent of country, bear so striking a resemblance in physical appearance and structure to each other; and their general habits, customs, and pursuits, are also so very similar, though modified in some respects by local circumstances or climate, that little doubt can be entertained that all have originally sprung from the same stock.

The principal points of difference, observable between various tribes, appear to consist chiefly in some of their ceremonial observances, and in the variations of dialect in the language they speak; the latter are, indeed, frequently so great, that even to a person thoroughly acquainted with any one dialect, there is not the slightest clue by which he can understand what is said by a tribe speaking a different one.
The only account I have yet met with, which professed to give any particular description of the Aborigines of New Holland, is that contained in the able papers upon this subject, by Captain Grey, in the second volume of his travels.

When it is considered, that the material for that purpose was collected by the author, during a few months interval between his two expeditions, which he spent at Swan River, and a short time subsequently passed at King George's Sound, whilst holding the appointment of Government Resident there; it is perfectly surprising that the amount of information amassed should be so great, and so generally correct, on subjects where so many mistakes are liable to be made, in all first inquiries, when we are ignorant of the character and habits of the people of whom information is to be sought, and unacquainted with the language they speak.
The subject, however, upon a portion of which Captain Grey so successfully entered, is very extensive, and one which no single individual, except by the devotion of a life-time, could hope fully to discuss.

The Continent of Australia is so vast, and the dialects, customs, and ceremonies of its inhabitants so varied in detail, though so similar in general outline and character, that it will require the lapse of years, and the labours of many individuals, to detect and exhibit the links which form the chain of connection in the habits and history of tribes so remotely separated; and it will be long before any one can attempt to give to the world a complete and well-drawn outline of the whole.
It is not therefore to satisfy curiosity, or to interrupt the course of inquiry, that I enter upon the present work; I neither profess, nor could I attempt to give a full or matured account of the Aborigines of New Holland.

Captain Grey's descriptions on this subject are limited to the races of South-western, as mine are principally directed to those of Southern Australia, with occasionally some remarks or anecdotes relating to tribes in other parts of the Continent with whom I have come in contact.
The character of the Australian native has been so constantly misrepresented and traduced, that by the world at large he is looked upon as the lowest and most degraded of the human species, and is generally considered as ranking but little above the members of the brute creation.
Savages have always many vices, but I do not think that these are worse in the New Hollanders, than in many other aboriginal races.
