government and the principle of property. Having adopted the other course, they pushed it to cruel and inexcusable lengths; punished many innocent persons, and suffered many of the really possessed to go free. For they whose madness was most to be apprehended, as most contagious, were not the wretches who fancied they possessed the power of bewitching others; but the _convulsionnaires_, who deemed themselves bewitched, and were their accusers. Certainly if the same epidemic should ever again break out among a European population, or even among a British population, the arm of the magistrate would be again required to suppress it, and we would be better able to judge of the conduct of those whom it has been the fashion of modern historians to represent as altogether ignorant and brutal executioners. So long as possession is only the result of manual passes, or of fixing the gaze on indifferent objects; so long as the effects are regarded as physical or psychological phenomena, due to a physical cause, and the pretensions of the practitioner are not rested on any peculiar religious sanction, there is no danger of mesmerism degenerating into a dangerous epidemic; but we might have seen a very different state of affairs if the magnetizers and biologists had referred their powers to any species of supernatural agency; and possibly would have found ourselves long since under the necessity of reviving those penal proceedings which we have so generally been taught to abhor, as among the most revolting remnants of mediæval superstition.(5) Even as it is, these powers of the biologist, if in truth they exist, are capable of fearful abuse. Let us take, for example, one of the oldest methods of exercising influence, for good or evil, on an absent person:— "As fire this figure hardens, made of clay, And this of wax with fire consumes away; Such let the soul of cruel Daphnis be, Hard to the rest of women, soft to me." If the waxen or clay image be but a concentrator of the good or evil will of the operator towards the distant object, and the witchcraft of the love-sick magician in Virgil, or of the evil-disposed wizard of the middle ages, be in truth no more than an exertion of biological power, it behoves society to take care how individuals should be suffered to acquire mesmerical relations with others, over whom they may exercise malignant as well as healing influences. If the pretensions of the biologists be established, biology must soon be put under medical supervision. But to return to the phenomena of possession.
