mystics of our own middle ages, who state that a man must be born a magician; in other words, that the gift is constitutional, though developed by practice and art. Now, that this gift and its practice should principally obtain in imperfect states of civilization, and fade into insignificance in the busy social enlightenment of cities, may be accounted for by reference to the known influences of imagination. In the cruder states of social life not only is imagination more frequently predominant over all other faculties, but it has not the healthful vents which the intellectual competition of cities and civilization affords. The man who in a savage tribe, or in the dark feudal ages, would be a magician, is in our century a poet, an orator, a daring speculator, an inventive philosopher. In other words, his imagination is drawn to pursuits congenial to those amongst whom it works. It is the tendency of all intellect to follow the directions of the public opinion amidst which it is trained. Where a magician is held in reverence or awe, there will be more practitioners of magic than where a magician is despised as an impostor or shut up as a lunatic. In Scandinavia, before the introduction of Christianity, all tradition records the wonderful powers of the Vala, or witch, who was then held in reverence and honour. Christianity was introduced, and the early Church denounced the Vala as the instrument of Satan, and from that moment down dropped the majestic prophetess into a miserable and execrated old hag!" "The ideas you broach," said I, musingly, "have at moments crossed me, though I have shrunk from reducing them to a theory which is but one of pure hypothesis. But this magic, after all, then, you would place in the imagination of the operator, acting on the imagination of those whom it affects? Here, at least, I can follow you, to a certain extent, for here we get back into the legitimate realm of physiology."
