In the month of December, 1894, I was invited by M. Aug. Lemaitre, Professor of the College of Geneva, to attend some seances of a non-professional medium, receiving no compensation for her services, and of whose extraordinary gifts and apparently supernormal faculties I had frequently heard. Having gladly accepted the invitation of my worthy colleague, I found the medium in question, whom I shall call Mlle. Helene Smith, to be a beautiful woman about thirty years of age, tall, vigorous, of a fresh, healthy complexion, with hair and eyes almost black, of an open and intelligent countenance, which at once invoked sympathy. She evinced nothing of the emaciated or tragic aspect which one habitually ascribes to the sibyls of tradition, but wore an air of health, of physical and mental vigor, very pleasant to behold, and which, by the way, is not often encountered in those who are good mediums. The number of those invited to take part in the seance being complete, we seated ourselves in a circle, with our hands resting upon the traditional round table of spiritistic circles. Mlle. Smith - who possesses a triple mediumship: visual, auditive, and typtological - began, in the most natural manner, to describe the various apparitions which passed before her eyes in the partially darkened room. Suddenly she stops and listens; she hears a name spoken in her ear, which she repeats to us with astonishment; then brief sentences, the words of which are spelled out by raps on the table, explain the meaning of the vision. Speaking for myself alone (there were three of us to divide the honor of the seance), I was greatly surprised to recognize in scenes which passed before my eyes events which had transpired in my own family prior to my birth. Whence could the medium, whom I had never met before, have derived the knowledge of events belonging to a remote past, of a private nature, and utterly unknown to any living person? The astounding powers of Mrs. Piper, the famous Boston medium, whose wonderful intuition reads the latent memories of her visitors like an open book, recurred to my mind, and I went out from that seance with renewed hope of finding myself some day face to face with the "supernormal" - a true and genuine supernormal - telepathy, clairvoyance, spiritistic manifestations, it matters not by what name it be called, provided only that it be wholly out of the ordinary, and that it succeed in utterly demolishing the entire framework of established present day science. I will designate under the names of "Hindoo" or "Oriental" cycle and "Royal" cycle the whole of the automatic manifestations relative to these two previous existences. I shall call the third romance the "Martian" cycle, in which Mlle. Smith, by virtue of the mediumistic faculties, which are the appanage and the consolation of her present life, has been able to enter into relation with the people and affairs of the planet Mars, and to unveil their mysteries to us. It is in this astronomical somnambulism that the phenomenon of glossolalia, appears, which consists of the fabrication and the use of an unknown language, and which is one of the principal objects of this study; we shall see, however, that analogous facts are likewise presented in the Hindoo cycle. The personality of Leopold maintains very complex relations with the preceding creations. On the one hand, it is very closely connected with the Royal cycle, owing to the fact that the name of Leopold is only a pseudonym under which is concealed the illustrious Cagliostro, who, it appears, was madly infatuated with Queen Marie Antoinette, and who now, discarnate and floating in space, has constituted himself the guardian angel in some respects of Mile. Smith, in whom after a long search he has again found the august object of his unhappy passion of a century ago. On the other hand, this role of protector and spiritual guide which he assumes towards Helene confers upon him a privileged place in her somnambulisms.
