Those of my readers who have carefully followed the cases of unusual mental action there presented--cases of thought-transference, of clairvoyance, of remarkable mind-action in the hypnotic trance and in natural somnambulism--in well marked examples of double consciousness as shown in the cases of Félida X., of Alma Z., of Ansel Bourne, and the hypnotic subject, Madame B., in her various personalities of Léonie, Léontine, and Léonore, in automatic action as displayed in Planchette-writing, in trance-speaking and in crystal-gazing, cannot have failed to observe, throughout the whole series, mind acting rationally and intelligently, quite independently of the ordinary consciousness, and even at times independently of the whole physical organization. We have considered the evidence which points to the fact, or at least to the theory of a subliminal self, or another personality, in some manner bound up in that complicated physical and mental mechanism which constitutes what we term an individual. We have seen that there are weighty proofs that such a secondary or subliminal, or, if you choose so to designate it, _supranormal_ self, actually exists, and that it exhibits functions and powers far exceeding the functions and powers of the ordinary self. We have seen it expressing its own personal opinions, its own likes and dislikes, quite different and opposite to the opinions, likes, and dislikes of the ordinary self; having its own separate series of remembered actions or chain of memories, its own antecedent history, and its separate present interests; and especially performing actions altogether beyond the powers of the ordinary self. We have seen it going out to great distances, seeing and describing scenes and events there taking place--for example, Swedenborg at Gottenburg witnessing the conflagration at Stockholm; Dr. Gerault's clairvoyant maid-servant, Marie, in France, seeing the sad death of her neighbor's son, Limoges, the ropemaker, while serving in the Crimea; and also the serious illness of Dr. Gerault's military friend in Algiers. Fitzgerald, at Brunswick, Me., seeing and describing the Fall River fire three hundred miles away, and Mrs. Porter, at Bridgeport, Conn., describing the burning of the steamer _Henry Clay_ while it was occurring on the Hudson River near the village of Yonkers. We have seen this same subliminal self in the case of Mr. Stead, going out and acquiring desired knowledge relating to the location, occupation, and needs of persons from whom he desired such information, and bringing it back and reporting it by means of automatic writing. Again, we have seen this subliminal self in the case of Mrs. Newnham, perceiving the silently written and sometimes even the unwritten questions of her husband, and automatically writing the answers by means of Planchette; and we have seen it producing hallucinations of hearing as in the case of Léonore causing Léontine to hear a voice reproving her for her flippancy.
