Many of the words and phrases of the language on the eastern and southern sides of Australia, as given in Collins’s work, in Threlkeld’s Grammar, and in several short vocabularies, are identical with those used on the Western side. And in a list of words given in Flinders’ Voyage, as used by the natives on the north-east coast at Endeavour River, the term for the eye is precisely the same as that at Swan River. Whilst this publication was in the press, the work of Captain Grey appeared; in the course of which he has treated of this subject at considerable length, and adduced several arguments conﬁrmatory of the same opinion.
