THE translation into English of From India to the Planet Mars has been undertaken in response to the demand created by the widespread and increasing interest which is manifesting itself both in Great Britain and the United States in the phenomena exhibited by its heroine—an interest which marks a new era in the progress of human knowledge. Twenty—even ten—years ago the phenomena which Prof. Flournoy here describes in detail, and of which he offers a keen, skilful, psychological analysis, would have met with the sneers of popular science and the contempt of obscurantist orthodoxy; the book would have found few readers. Times have greatly changed since the Society for Psychical Research was founded, eighteen years ago, by a few thoughtful men (included among them were those whose names would have conferred honor upon any body of men) interested in the investigation of abnormal mental or psychic phenomena. In explaining their reasons for organizing that The organization of this society constituted the first attempt in the world's history to investigate the phenomena of clairvoyance, automatic writing and speaking, trance conditions, second sight, apparitions of persons at the point of death, alleged spirit messages, etc., by a scientific body formed upon a broad basis. As was to have been expected, the work and aims of the society were met by a storm of derision and ridicule, and by attacks which poured in from every quarter, the bitterest of which came from the always too numerous class of narrow-minded scientists, whose partisan prejudices, confining them to a narrow rut, hinder their seeing anything from a point of view other than that of their preconceived hypotheses, and prevent them from attaining that open-mindedness which is indispensable to and one of the first requisites of a true scientist in any field of investigation. While, it is true, the great majority of men are still skeptical as to the ability of science ever to solve this problem, it is, however, a fact that a continually increasing number of thoughtful men are coming to believe that the hidden subliminal world within us may point to an unseen but spiritual world without, communication with which, if once established, would furnish us with the solution so ardently longed for. Such men do not believe that it behooves them to be content with the passivity of pure Agnosticism are not willing that Ignoramus et Ignorabimus should be their only creed. They are beginning to search for new facts in the domain of the human mind, just as they have searched for and found them everywhere else they have looked for them. Mr. F. W. H. Myers, the pioneer and leader of the psychical research movement, in an address recently delivered, says: "Starting from various stand-points, we endeavor to carry the newer, the intellectual virtues into regions where dispassionate tranquillity has seldom yet been known. . . . First, we adopt the ancient belief—implied in all monotheistic religion, and conspicuously confirmed by the progress of modern science—that the world as a whole, spiritual and material together, has in some This is just what Prof. Flournoy has endeavored to do in regard to the strange phenomena manifested by Mlle. Helene Smith. No fact has been regarded by him as too trivial to escape his keen, careful scrutiny from a psychological point of view. The first task which the investigators of these obscure mental phenomena set themselves was, naturally, that of separating and sifting the real, actually existent facts from the mass of fraud and deception in which mercenary charlatans, aided by the easy credulity of the simple-minded, had contrived so completely to bury from sight the true phenomena that for a long time the intelligent public refused utterly to believe in the existence of any real phenomena of the kind, but insisted that everything when fully probed would be found to be mere delusion, the result of trickery and fraud. Probably no scientific fact since the dawn of modern science has required so great a weight of cumulative evidence in its favor to establish the Guided by these two principles, Prof. Flournoy has come to the conclusion that Mlle. Smith really possesses the faculty of telekinesis—the ability to move ponderable objects situated at a distance, without contact and contrary to known natural Whether the individual reader adopts the author's views and theories, or finds in others a more natural explanation of the facts narrated by Prof. Flournoy, he cannot fail to admire the frankness, candor, and entire freedom from prejudice displayed by him. He evinces a true, open-minded, scientific spirit, never distorting facts in order to make them fit his hypotheses, and freely admitting the possibility of the discovery of new facts at any time, of a nature to compel him to adopt some other hypothesis than that which he has provisionally assumed to explain the phenomena. A word on another subject before the reader goes on to the perusal of this narrative of strange facts: One who is interested in Psychical Research,—when he has finally succeeded in convincing some obstinate skeptic of the genuineness of the phenomena—when the doubter has at last yielded to the weight of evidence, then, very frequently, the next question, From this conclusion the followers of Psychical Research emphatically dissent. It seems passing strange to them that such an opinion should be held by intelligent men at the present stage of development of human knowledge, in view of the mighty discoveries which have been wrested from nature by the laborious process of persevering observation of seemingly trivial facts. An eighteenth-century writer might with some show of reason have made a similar observation in regard to Dr. Franklin and his experiments with kite and key in a thunder-storm. It would indeed, at that epoch, have seemed unlikely that science would succeed in discovering the secret of the electric fluid by such means. But to-day, at the dawn of the "Out of the long Stone Age our race is awakening into consciousness of itself. We stand in the
