Almost all writers unite in speaking of it as mysterious, and yet the facts are patent, are manifest to every observer on the spot. There is no more mystery connected with their decay than with the extinction of the dodo or the bison. It cannot be doubted that the New World races have suffered or are suffering extinction in consequence of the introduction among them of Old World diseases, and because of one other cause, also an importation, of which more hereafter. So much is quite beyond dispute, and these causes may be seen in operation over half the world at the present day—in North and South America, in Australia, in New Zealand, in the islands of the Pacific, as well as in the Andamans, and several other of the oceanic islands of the Eastern Hemisphere.

In India and Ceylon are tribes of an exceedingly wild type that have
