Now before proceeding farther and thus entering upon ground which is very little known, there are several important circumstances worthy of consideration. In the vast extent of country which is comprised between the points embraced in these tables it was to have been expected that very great variations of dialect would have been found. If we only reflect upon the differences of dialect existing between the several counties of England, so limited in extent, how much greater were the variations to have been reasonably anticipated in a country between two and three thousand miles across, where an unwritten language is in use, and where no communication whatever takes place between the inhabitants of distant portions: moreover in this great extent the vegetation becomes totally different; birds, reptiles, and quadrupeds inhabit one portion of the continent which are unknown in another, and external nature altogether changes. Under these circumstances many new words must have been invented, and new terms must constantly have been introduced as the population spread across the country, and as those who were constantly pushing on from the outskirts of the inhabited parts ceased to communicate with the districts which had been first peopled, these changes must have been unknown to the original inhabitants of the continent and to those of their descendants who successively inhabited their territory. If for instance this country was first peopled from the north or the tropical parts, the most remote inhabitants of the southern portions must have invented terms for snow, ice, hail, intense cold, etc., as well as for every tree and bird, for every fish and reptile, and for every insect; all the compound and comparative terms derived from these, as well as the original words, we ought therefore to expect to find totally different in the languages of the north and south, of the east and west; and from whatever portion of the continent we imagine the first inhabitants to have proceeded the same reasoning holds good. RADICAL IDENTITY OF THE PRONOUNS. But personal terms, such as the parts of the body, the pronouns, etc., and also verbs describing ordinary actions, ought not to be expected to vary in the same degree; and we shall accordingly find that it is chiefly in words of these and similar classes that the greatest degree of resemblance is found to exist. With regard to the pronouns this is very remarkable. In the singular, plural, and dual numbers they almost coincide in Western Australia, South Australia, and Sydney. The following table of the pronouns as used in those places will show this: (TABLE OF PRONOUNS.) DIFFERENCES OF DIALECT EXPLAINED. EXAMPLES.
