EXAMPLES.
To those who have not considered this circumstance languages have frequently appeared to be quite different which in reality are closely assimilated.

Two instances will explain my meaning.

The natives in the vicinity of Perth generally use the word gab-by, or kuyp-e, for water, but those inhabiting a district only twelve or fourteen miles distant from Perth adopt the word kow-win; the word used by the natives in the vicinity of Adelaide in South Australia for water is kauw-ee.

Now, on comparing these words it might have been hastily concluded that the languages of West and South Australia were without affinity; but in fact the variation does not constitute any essential difference, for, considering the interchangeable nature of the consonants b, p, and w, and of g and k, which affect different dialects, we shall find the words gab-by, kuyp-e, kow-win and kauw-ee to be only different forms from one root.

One instance of another kind may be given.
