regions, where its unity of principle developes itself in endless variety of form. There may indeed be a remote historical connexion at the root of some of the analogies in myths from far distant regions, which have just been mentioned; but when resemblances in Mythology are brought forward as proofs of such historical connexion, they must be closer and deeper than these. Mythological evidence, to be used for such a purpose, requires a systematic agreement in the putting together of a number of events or ideas, which agreement must be so close as to make it in a high degree improbable that two such combinations should have occurred separately, or at least the tales or ideas found alike in distant regions must be of so quaint and fantastic a character as to make it, on the very face of the matter, unlikely that they should have been invented twice. But it is both easier and safer to appeal to the effects of known intercourse between different peoples in spreading beliefs and popular tales, as evidence of the way in which historical connexion really docs record itself in Mythology, than to lay down à priori rules as to what the effects of such connexion ought to be.
When we consider how short the time is since the Indians of North America have been acquainted with guns, the fact that there has been recorded, as one of their native beliefs, the notion that there are men who have charmed lives, and can only be killed with a silver bullet, may prepare us for the way in which savages can take up foreign mythology into their own. Again, it might be naturally expected that Bible stories learnt from missionaries, settlers, and travellers, should pass in a more or less altered shape into the folk-lore of savage races. Moffat gives a good instance which happened to himself. He had never succeeded in finding a deluge-tradition in South Africa, but making inquiries in a Namaqua village, he came upon a somewhat intelligent native who had one to tell, so he began with great satisfaction to take it down in writing. By the time it was finished, however, he began to suspect, for it bore the impress of the Bible, though the Hottentot declared that he had received it from his forefathers, and had never seen or heard of a missionary. Mr. Moffat was puzzled, and suspended his
