They are energetic, demonstrative, joyous, and laughter-loving, and in all these particulars they differ widely from the Malay.
I believe, therefore, that the numerous intermediate forms that occur among the countless islands of the Pacific, are not merely the result of a mixture of these races, but are, to some extent, truly intermediate or transitional; and that the brown and the black, the Papuan, the natives of Gilolo and Ceram, the Fijian, the inhabitants of the Sandwich Islands and those of New Zealand, are all varying forms of one great Oceanic or Polynesian race.
It is, however, quite possible, and perhaps probable, that the brown Polynesians were originally the produce of a mixture of Malays, or some lighter coloured Mongol race with the dark Papuans; but if so, the intermingling took place at such a remote epoch, and has been so assisted by the continued influence of physical conditions and of natural selection, leading to the preservation of a special type suited to those conditions, that it has become a fixed and stable race with no signs of mongrelism, and showing such a decided preponderance of Papuan character, that it can best be classified as a modification of the Papuan type.

The occurrence of a decided Malay element in the Polynesian languages, has evidently nothing to do with any such ancient physical connexion.

It is altogether a recent phenomenon, originating in the roaming habits of the chief Malay tribes; and this is proved by the fact that we find actual modern words of the Malay and Javanese languages in use in Polynesia, so little disguised by peculiarities of pronunciation as to be easily recognisable--not mere Malay roots only to be detected by the elaborate researches of the philologist, as would certainly have been the case had their introduction been as remote as the origin of a very distinct race--a race as different from the Malay in mental and moral, as it is in physical characters.
As bearing upon this question it is important to point out the harmony which exists, between the line of separation of the human races of the Archipelago and that of the animal productions of the same country, which I have already so fully explained and illustrated.

The dividing lines do not, it is true, exactly agree; but I think it is a remarkable fact, and something more than a mere coincidence, that they should traverse the same district and approach each other so closely as they do.

If, however, I am right in my supposition that the region where the dividing line of the Indo-Malayan and Austro-Malayan regions of zoology can now be drawn, was formerly occupied by a much wider sea than at present, and if man existed on the earth at that period, we shall see good reason why the races inhabiting the Asiatic and Pacific areas should now meet and partially intermingle in the vicinity of that dividing line.
It has recently been maintained by Professor Huxley, that the Papuans are more closely allied to the negroes of Africa than to any other race.
The resemblance both in physical and mental characteristics had often struck myself, but the difficulties in the way of accepting it as probable or possible, have hitherto prevented me front giving full weight to those resemblances.
