A friend of Mr. Martin, the author of a work on "Second Sight," used to recite several stanzas belonging to such a prophetic song, which he had heard himself on a sad November day, as it came to him through the drooping clouds and sweeping mists from the summit of a lonely mountain. At funerals also, wonderful voices were heard high in the air, as they accompanied the chanting of the people below, with a music not born upon earth, and filling the heart with strange but sweet sadness. Nearly the same visions are seen and the same songs are heard in Sweden and Norway, proving conclusively that like climatic influences produce also a similar magic life, in individuals not only, but in whole nations. For even if we are disposed to look upon these phenomena as merely strange appearances of clouds and mists, accompanied by the howling and whistling of the wind and the tumbling down of rocks and gravel, there remains the uniformity with which thousands of every generation interpret these sights and sounds into weird visions and solemn chantings. It is, however, not quite so evident why the peculiar class of visions which is often erroneously called second sight--the beholding of a "double"--should be almost entirely confined to these same northern regions. It is, of course, not unknown to other lands also, and even Holy Writ seems to justify the presumption that the idea of a "double" was familiar to the people of Palestine. For the poor damsel Rhoda, who "for gladness" did not open the door at which Peter knocked, after he had been miraculously liberated, but ran to announce his presence to the friends who were assembled at the house of Mark's brother, was first called mad, and then told: "It is his angel" (Acts xii. 13). They evidently meant, not that it was the spirit of their deceased friend, since they would have been made aware of his death, but a phantom representing his living body. But the number of authentic cases of persons who have seen their own form, is vastly greater at the North than anywhere else. The Celtic superstition of the "fetch," as the appearance of a person's "double" is there called, is too well known to require explanation. But the vision itself is one of the most interesting in the study of magic, since it exhibits most strikingly the great power which the human soul may, under peculiar circumstances, gain and exercise over its own self, leading to complete self-delusion.
