one very powerful argument against miracles with men of intelligence (and especially with such as are acquainted with the full scope of the revelations of modern science), is derived from the prevalent assumption that, if real, they are the direct acts of the Deity The nature of these acts is often such, that no cultivated mind can for a moment impute them to an infinite and supreme being. Few if any reputed miracles are at all worthy of a God; and it is the man of science who is best enabled to form a proper conception of the lofty and unapproachable nature of the attributes which must pertain to the supreme mind of the universe. Strange to say, however, he is in most cases illogical enough to consider the difficulties in the way of this assumption as a valid argument against the facts in question having ever occurred, instead of being merely one against the mode of interpreting them. He even carries this objection further, by the equally unfounded assumption that any beings who could possibly produce the asserted phenomena must be mentally of a high order, and therefore, if the phenomena do not accord with his ideas of the dignity of superior intelligences, he simply denies the facts without examination. Yet many of these objectors admit that the mind of man is probably not annihilated at death, and that therefore countless millions of beings are constantly passing into another mode of existence, who, unless a miracle of mental transformation takes place, must be very far inferior to himself. Any argument, therefore, against the reality of phenomena having been produced by preter-human intelligences, on account of the trivial or apparently useless nature of such phenomena, has really no logical bearing whatever upon the question. The assumption that all preter-human intelligences are more intellectual than the average of mankind, is as utterly gratuitous, and as powerless to disprove facts, as that of the opponents of Galileo when they asserted that the planets could not exceed the perfect number, seven, and that therefore the satellites of Jupiter could not exist. Let us now return to the consideration of the probable nature and powers of those preter-human intelligences, whose possible existence only it is my object at present to maintain.

I have in the first part of this paper given reasons for supposing that there might be, and probably are, other (and perhaps infinitely varied) forms of matter and modes of ethereal motion, than those which our senses enable us to recognise. We must therefore admit that there may be and probably are, organisations adapted to act upon and to receive impressions from them. In the infinite universe there may be infinite possibilities of sensation, each one as distinct from all the rest as sight is from smell or hearing, and as capable of extending the sphere of the possessor's knowledge and the development of his intellect, as would the sense of sight when first added to the other senses we possess. Beings of an ethereal order, if such exist, would probably possess some sense or senses of the nature above indicated, giving them increased insight into the constitution of the universe, and proportionately increased intelligence to guide and direct for special ends those new modes of ethereal motion, with which they would in that case be able to deal. Their every faculty might be proportionate to the modes of action of the ether. They might have a power of motion as rapid as that of light or the electric current. They might have a power of vision as acute as that of our most powerful telescopes and microscopes. They might have a sense somewhat analogous to the powers of the last triumph of science, the spectroscope, and by it be enabled to perceive instantaneously the intimate constitution of matter under every form, whether in organised beings or in stars and nebulae. Such existences possessed of such, to us, inconceivable powers, would not be supernatural, except in a very limited and incorrect sense of the term. And if those powers were exerted iu a manner to be perceived by us, the result would not be a miracle, in the sense in which the term is used by Hume or Tyndall. There would be no "violation of a law of nature;" there would be no "invasion of the law of conservation of energy." Neither matter nor force would be created or annihilated, even though it might appear so to us. In an infinite universe the great reservoir of matter and force must be infinite; and the fact that an ethereal being should be able to exert force, drawn perhaps from the boundless ether, perhaps from the vital energies of human beings, and make its effects visible to us as an apparent "creation," would be no more a real miracle, than is the perpetual raising of millions of tons of water from the ocean, or the perpetual exertion of animal force upon the earth, both of which we have only recently traced immediately to the sun, and perhaps remotely to other and varied sources lost in the immensity of the universe. All would be still natural. The great laws of nature would still maintain their inviolable supremacy. We should simply have to confess with a modern man of science, that "our five senses are but clumsy instruments to investigate the imponderables," and might see a new and deeper meaning in the oft-quoted but little heeded words of the great poet, when he reminds us that "there are more things in heaven and earth than are dreamt of in our philosophy."

It would appear then, if nay argument has any weight, that there is nothing self-contradictory, nothing absolutely inconceivable, in the idea of intelligences uncognisable directly by our senses, and yet capable of acting more or less powerfully on matter. There is only to some minds a high improbability, arising from the supposed absence of all proof that there are such beings. Let direct proof be forthcoming, and there seems no reason why the most sceptical philosopher should refuse to accept it. It would be simply a matter to be investigated and tested like any other question of science. The evidence would have to be collected and examined. The results of the inquiries ot different observers would have to be compared. The previous character of the observers for knowledge, accuracy, and honesty, would have to be weighed, and some, at least, of the facts relied on would have to be re-observed. In this manner only could all sources of error be eliminated, and a doctrine of such overwhelming importance be established as truth. I propose now to inquire whether such proof has been given, and whether the evidence is attainable by any one who may wish to investigate the subject in the only manner by which truth can be reached —by direct observation and experiment.

The first fact capable of proof is this:—That during the last eighteen years, while physical science has been progressing with rapid strides, and the growing spirit of rationalism has led to a very general questioning of all facts of a supposed miraculous or supernatural character, a continually increasing number of persons maintain their belief in the existence of beings of the nature of those we have hitherto postulated as a bare possibility. All these persons declare that they have received direct and oft-repeated proofs of the existence of such beings. Most of them tell us they have been convinced against all their previous notions and prepossessions. Very many have previously been materialists, not believing in the existence of any intelligences disconnected from a visible, tangible form, nor in the continued existence of the mind of man after death. At the present moment there are at least three millions of persons in the United States of America who have received to them satisfactory proofs of the existence of invisible intelligences; and in this country there are many thousands who declare the same thing. A large number of these persons continually receive fresh proofs in the privacy of their own homes, and so much interest is felt in the subject that six periodicals are published in London, several on the Continent, and a very large number in America, which are exclusively devoted to disseminating information relating to the existence of these invisible intelligences and the means of communicating with them. A little enquiry into the literature of the subject, which is already very extensive reveals the startling fact that this revival of so-called supernaturalism is not confined to the ignorant or superstitious, or to the lower classes of society. On the contrary, it is rather among the middle and upper classes that the larger proportion of its adherents are to be found; and among those who have declared themselves convinced of the reality of facts such as have been always classed as miracles, are numbers of literary, scientific, and professional men, who always have borne and still continue to bear high characters, are above the imputation either of falsehood or trickery, and have never manifested indications of insanity. Neither is the belief confined to any one religious sect or party. On the contrary, men of all religions and of no religion are alike to be found in the ranks of the believers; and as already stated, many entire sceptics as to there being any superhuman intelligences in the universe, have declared that by the force of direct evidence they have been, however unwillingly, compelled to believe that such intelligences do exist. Here is certainly a phenomenon altogether unique in the history of the human mind. In examining the evidence of similar prodigies during past ages, we have to make much allowance for early education, and the almost universal pre-existing belief in the possibility and frequent occurrence of miracles and supernatural appearances. In the present day it is a notorious fact that among the educated classes, and especially among students of medicine and science, the scepticism on such subjects is almost universal. But what seems the most extraordinary fact of all, and one that would appear to be absolutely inconsistent with any theory of fraud, imposture, or self-delusion, is, that during the eighteen years which have elapsed since the revival of a belief in the supernatural in America, not one single individual has carefully investigated the subject without accepting the reality of the phenomena, and while thousands have been converted to the belief, not one adherent has ever been converted back from it. While the peculiarly constituted individuals who are the media of the phenomena may be counted by thousands, not one has ever exploded the imposture, if imposture it be. And of the few who receive payment for giving up their time to those who wish to witness the manifestations, it is remarkable that no one has yet tried to be first in the market with a full history of the wonderfully ingenious apparatus and extraordinary dexterity that must have been requisite to make dupes of many millions of people and to establish a new literature and a new religion. They must be very blind not to see that such a work would be a most profitable speculation.

In order that my readers may judge for themselves whether delusion or deception will best account for these facts, or whether we have indeed made a discovery more important and more extraordinary than any that has yet distinguished the nineteenth century, I propose to bring before them a few witnesses, whose evidence it will be well for them to hear before forming a hasty judgment. I shall call chiefly persons connected with science, art, or literature, and whose intelligence and truthfulness in narrating their own observations are above suspicion; and I would particularly insist, that no objections of a general kind can have any weigh!; against direct evidence to special facts, many of which are of such a nature that there is absolutely no choice between believing that they did occur, or imputing to all who declare they witnessed them, wilful and purposeless falsehood.
