India and China each well-nigh deserve the status of geographical provinces on their own account. Each is an area of settlement; and, once there is settlement, there is a cultural influence which co-operates with the environment to weed out immigrant forms; as we see, for example, in Egypt, where a characteristic physical type, or rather pair of types, a coarser and a finer, has apparently persisted, despite the constant influx of other races, from the dawn of its long history. India, however, and China have both suffered so much invasion from the Eurasian northland, and at the same time are of such great extent and comprise such diverse physical conditions, that they have, in the course of the long years, sent forth very various broods of men to seek their fortunes in the south-east. Nor must we ignore the possibility of an earlier movement in the opposite direction. In Indonesia, the home of the orang-utan and gibbon, not to speak of Pithecanthropus, many authorities would place the original home of the human race. It will be wise to touch lightly on matters involving considerations of palaeo-geography, that most kaleidoscopic of studies. The submerged continents which it calls from the vasty deep have a habit of crumbling away again. Let us therefore refrain from providing man with land-bridges (draw-bridges, they might almost be called), whether between the Indonesian islands; or between New Guinea, Australia and Tasmania; or between Indonesia and Africa by way of the Indian Ocean. Let the curious facts about the present distribution of the racial types speak for themselves, the difficulties about identifying a racial type being in the meantime ever borne in mind.
