The healthy rose emits an agreeable odor which our senses appreciate. You may destroy the rose - it does not prove that the fragrance which it emitted does not still exist even though our senses fail to appreciate it.

But experiment and scientific methods have also somewhat to say upon this subject. And first, in August, 1874, twenty-two years ago, at the moment when the materialistic school was at the height of its influence, both the scientific and religious world were brought to a momentary standstill - like a ship under full headway suddenly struck by a tidal wave - when one of the most eminent scientific men of his time, or of any time, standing in his place as president of the foremost scientific association in the world, spoke as follows: "Abandoning all disguise, the confession which I feel bound to make before you is that I prolong the vision backward across the boundary of experimental evidence and discover in matter, which we, in our ignorance, and notwithstanding our professed reverence for its Creator, have hitherto covered with opprobrium, the promise and potency of every form of life." *

On that day the tap-root of materialism was wounded, and materialism itself has been an invalid of increasing languor and desuetude ever since. On the other hand, supernaturalism in every form was left in little better plight.

To thinking men of all classes this bold declaration opened up the grand thought, not new, but newly formulated and endorsed, that as the seed contained all the possibilities of the future plant - the ovum all the possibilities of the future animal, so matter, which had been thought so lightly of, contained within itself the germ, potency, and promise of nature in all her subsequent developments - of the vast universe of suns and systems, planets and satellites, and of every form of life, sensation, and intelligence which in due process of evolution has appeared upon their surfaces. It pointed the way to the thought of an infinite causal energy and intelligence pervading matter and working through nature in all its various grades of life from the first organized cell up to the grandest man. It gave a new meaning to mind in man, as being an individualized portion of that divine potency which ever existed in matter, and which acting through constantly improving and developing organisms, amidst constantly improving environments, at length appeared a differentiated, individualized, seeing, reasoning, knowing, loving spirit.

The mind, then, is of importance. It is no transient visitor which may have made its appearance by chance - a concatenation of coincidences, fortunate or unfortunate, but it is the intelligent tenant and master of a singularly beautiful and complicated house, a house which has been millions upon millions of years in the building, and yet which will be lightly laid aside when it ceases to accommodate and fulfil the needs of its tenant.

Who and what, then, is this lordly tenant whose germ was coeval with matter, whose birth was in the first living cell which appeared upon the planet, whose apprenticeship has been served through every grade of existence from the humble polyp upwards, whose education has been carried on through the brain and organs of every grade of animal life with its countless expedients for existence and enjoyment, until now, as lord of its domain, it looks back upon its long course of development and education, looks about upon its environments and wonders at itself, at what it sees, and at what it prophesies. Truly what is this tenant, what are its powers, and why is it here at all?

These are the questions which it has been the business of the strongest and wisest to discuss, from the time men began to think and record their thoughts until the present time; but how various and unsatisfactory have been the con-'clusions. The mental philosophers, psychologists, and encyclopedists simply present a chaos of conflicting definitions, principles, and premises, upon none of which are they in full agreement amongst themselves; they are not even agreed regarding the nature of mind - whether it is material or immaterial - how it should be studied, how it is related to the body, indeed whether it is an entity at all, or simply "a series of feelings or possibilities of them"; whether it possesses innate ideas or is simply an accretion of experiences. In short, the stock of generally received facts relating to mind has always remained exceedingly small. Psychologists have busied themselves chiefly about its usual and obvious actions, and when in full relation to the body, ignoring all other mental action or arbitrarily excluding it as abnormal and not to be taken into account in the study of normal mind; so with only half the subject under consideration true results could hardly be attained.

Since the organization of the Society for Psychical Research, in 1882, new fields of investigation have been undertaken and the unusual phenomena connected with the operations of mind have been systematically studied. A very hasty and imperfect sketch of this study and of the results obtained has been given in the preceding chapters, but for the use here made of these studies in connection with his own observations the writer alone is responsible. In these studies the field of investigation has been greatly extended beyond that examined by the old philosophers and physiologists. Beyond the usual activities in which we constantly see the mind engaged - observation of surroundings made by the senses, memory of them, reasoning about them, and putting them in new combinations in science, literature, or art - new activities have been observed, activities lying entirely outside the old lines, in new and hitherto unexplored fields.

It has been demonstrated by experiment after experiment carefully made by competent persons that sensations, ideas, information, and mental pictures can be transferred from one mind to another without the aid of speech, sight, hearing, touch, or any of the ordinary methods of communicating such information or impressions. That is, Telepathy is a fact, and mind communicates with mind through channels other than the ordinary use of the senses.
