Magic divination in point of time includes the class of generally very vague and indefinite perceptions, which we call presentiments. These are, unfortunately, so universally mixed up with impressions produced after the occurrence--_vaticinium post eventum_--that their value as interesting phenomena of magic is seriously impaired. There remains, however, in a number of cases, enough that is free from all spurious admixture, to admit of being examined seriously. The ancients not only believed in this kind of foresight, but ascribed it with Pythagoras to revelations made by friendly spirits; in Holy Writ it rises almost invariably, under direct inspiration from on high, to genuine prophecy. It reveals not only the fate of the seer, but also that of others, and even of whole nations; the details vary, of course, according to the prevailing spirit of the times. When Narses was ruling over Italy, a young shepherd in the service of Valerianus, a lawyer, was seized by the plague and fell into syncope. He recovered for a time, and then declared that he had been carried to heaven, where he had heard the names of all who in his master's house should die of the plague, adding that Valerianus himself would escape. After his death everything occurred as he had predicted. An English minister, Mr. Dodd, one night felt an irresistible impulse to visit a friend of his who lived at some distance. He walked to his house, found the family asleep, but the father still awake and ready to open the door to his late visitor. The latter, very much embarrassed, thought it best to state the matter candidly, and confessed that he came for no ostensible purpose, and really did not know himself what made him do so. "But God knew it," was the answer, "for here is the rope with which I was just about to hang myself." It may well be presumed that the Rev. Mr. Dodd had some apprehensions of the state of mind of his friend; but that he should have felt prompted to call upon him just at that hour, was certainly not a mere accident.
