among the Somalis and the Gallas, in the region where M. Broca has an idea that some dark, and not Negro, race, now extinct, once existed. At the meeting of the British Association, 1898, Mr. W. Crooke gave expression to the view that the Dravidians represent an emigration from the African continent, and discounted the theory that the Aryans drove the aboriginal inhabitants into the jungles with the suggestion that the Aryan invasion was more social than racial, viz., that what India borrowed from the Aryans was manners and customs. According to this view, it must have been reforming aborigines who gained the ascendancy in India, rather than new-comers ; and those of the aborigines who clung to their old ways got left behind in the struggle for existence.
In an article devoted to the Australians, Professor R. Semon writes as follows. "We must, without hesitation, presume that the ancestors of the Australians stood, at the time of their immigration to the continent, on a lower rung of culture than their living representatives of to-day. Whence, and in what manner, the immigration took place, it is difficult to determine. In the neighbouring quarter of the globe there lives no race, which is closely related to the Australians. Their nearest neighbours, the Papuans of New Guinea, the Malays of the Sunda Islands, and the Macris of New Zealand, stand in no close relationship to them. On the other hand, we find further away, among the Dravidian aborigines of India, types which remind us forcibly of the Australians in their anthropological characters. In drawing attention to the resemblance of the hill-tribes of the Deccan to the Australians, Huxley says: 'An ordinary cooly, such as one can see among the sailors of any newly-arrived East India vessel, would, if stripped,
