It can hardly be denied that the question of spiritualism is forcing itself every year more and more upon the public attention; and that a belief in the reality of its phenomena, and, as almost a necessary consequence, a suspicion of their at least partially preternatural character, is on the increase amongst honest and intelligent persons. By preternatural phenomena, I mean manifestations of the operation of intelligences that are not clothed in flesh and blood; for with other than such as are so clothed, in the way of the senses, which is the way of nature, we have no acquaintance. I believe that few will examine seriously and patiently the phenomena of spiritualism as a whole without coming upon much that they cannot, without doing violence to their natural instincts, attribute to anything but preternatural agency. Whether they reduce this to white spirits or black, red spirits or gray, will depend for the most part on the religious prepossessions of the inquirers. I have said the phenomena as a whole, because some of these, such as cases of tables turning, upon which the hands of the company are resting, and, again, many of the communications through mediums speaking in trance or otherwise, do not necessarily suggest preternatural interference. The phenomena on which I am inclined to lay most stress are, 1st, physical manifestations--the movement or raising in the air, without contact of any sort, of heavy bodies, whether animate or inanimate; 2d, intelligent manifestations involving the communication of true information through a human medium, which was unknown at the time both to the medium and recipient. Such phenomena are not unfrequent at successful séances, and spiritualists have a right to demand that we should criticise their successes rather than their failures. For examples of the phenomena of modern spiritualism, we shall depend mainly upon two volumes: _Experiences in Spiritualism with D. D. Home_, and the _Report of the Committee of the London Dialectical Society_. The former is a well-known though unpublished relation of seventy-eight séances; the relaters are gentlemen whose names are guarantees for intelligence and honor. Of these séances, some were held in rooms which Mr. Home had never before entered, others in a variety of rooms belonging to gentlemen taking part in the proceedings. The supposition of concealed machinery, possible enough were it question of the magician's own den, is thus effectually precluded. The _Report_ is a still more remarkable volume. Even if spiritualism were exploded absolutely, this volume would still retain its interest as a unique collection of mental photographs representing every attitude which it is possible for the human mind to take up with regard to spiritualistic phenomena, from irreconcilable repulsion, through every shade of intelligent hesitation, to complete acceptance.
