this barter do not see each other, much less speak with each other. But where such seclusion exists, how is it possible for a strange language to penetrate? This problem appears almost insoluble. Nevertheless, a solution that appears at least probable was suggested by the investigations of Kern, an able Dutch scholar. His studies were based mainly on the development of the various Malayan idioms. A remarkable exception to the rule that primitive tribes have adopted the language of their more civilized neighbours came to light in the case of the Negritos of the Philippines. Their neighbours, as well as those of the tribes of the interior of Malacca, belong to that much-migrating race, the Malayans. If we compare the Negrito word-formations that have been collected during the past forty years with the vocabulary of the neighbouring Malayans, it is evident that all the words are entirely different, or at least seem to be so with few exceptions. When, however, Kern traced the probable development of these words, and compared them, not with the present-day usage of the Malays but with older stages of their language, he found that the latter invariably contained the counterparts of the Negrito words. Thus, while these Negritos have remained untouched by the present-day Malays, who probably entered the country at least several centuries ago, they have evidently derived their language from a Malayan influx that occurred much earlier still. To this may be added the demonstrable fact, gleaned from another source, that from very early times the Malayan tribes undertook migrations at widely separated intervals. Traversing the seas in their unsteady boats, they at various times peopled such islands, in particular, as were not too remote from the mainland. Now the testimony of language, to which we have referred, demonstrates that there were at least two such migrations to the Philippines, and that they occurred at widely different times. The original Malayan dialect, which has now become extinct or unknown to the modern Malays, was assimilated by the Negrito peoples, who probably occupied this territory before the arrival of any of the Malays. But this leads to a further inference. If the language was appropriated in prehistoric times and if the conditions of the present are such as would make this scarcely possible, we must conclude that the interrelations of the immigrants and the original inhabitants were formerly not the same as those that now prevail. And, as a matter of fact, this seems altogether probable, if we call to mind the descriptions which modern travellers give of their experiences among these primitive peoples. The traits of character that particularly distinguish them are fear and hatred of their more civilized neighbours; corresponding to this, is the contempt felt by the latter, because of their higher culture, for the more primitive peoples. The only thing that restrains the immigrant people
