The greatest hallucination is to believe that one knows all the laws of nature.

Let us now consider the reports of certain experimenters concerning the production of complete materialization in controlled seances. We have just read Professor Morselli's affirmation of having seen these great phenomena when Eusapia was bound upon a couch. As his testimony is particularly valuable we sought the report of one of these seances to which he alludes, and found it in the former Revue des Etudes Psychiques (Review of Psychical Studies, Sept., 1902), Edited at that time by Mr. C. de Vesine. That was the hey-day of the medium-ship of Eusapia Paladino, whose power has since declined.

Seance of Eusapia at Genoa, in 1902. Abridged account by Dr. J. Venzano, of Genoa.

"A small rectangular table of white wood was placed about twenty centimeters from the cabinet: about a meter from it was arranged a double row of chairs. A piano was set diagonally in a corner of the room which was brilliantly lighted by a gas chandelier, equipped with Auer burners.

"Before beginning the seance Madame Paladino, the medium, was rigorously examined. In our presence some of her clothing was removed, but the more detailed inspection was conducted by Mmes. Avellino and Montaldo in another room where the medium undressed completely.

"The medium then re-clothed herself in the presence of the two ladies, who did not leave her for an instant and accompanied her directly to the experimental room.

"The seance began at half-past ten o'clock. Madame Paladino seated herself at one end of the table, at her right Prof. Morselli, at her left, Boz-zano: each laid a hand and foot upon one hand and one foot of the medium.

"Almost at once the table was set in motion. The medium invited Dr. Morselli to place his free hand and arm upon her knees, in order to be assured of their immobility. The table rose more than forty centimeters, remaining suspended in air for almost a minute.

"Note that during the levitation, the hands of the spectators were all raised: only the right hand of the medium, joined to Morselli's left, barely touched the surface of the table, while her left hand, free, Was also lifted.

"Shortly afterward there was a second levitation of the same duration. Almost immediately Eusapia rose, lifted the curtains of the cabinet and lay on her back upon the bed, to the bars of which Prof. Morselli and Signor Avellino fastened her firmly. They attached her wrists to the iron bars at the sides by means of a cord with many knots: they then passed the cord twice around the waist of the medium, securely knotting the ends of the rope to the bars. They lowered the light, but so little that one could still read, as Prof. Morselli remarked, the smallest print on a paper.

"After about a quarter of an hour, the table, which stood a meter from us and twenty centimeters from the cabinet, began to move by itself. At first, it rose upon two feet, giving several raps.

"Sometime later the curtains stirred, as though they had been parted by two hands, and a large opening formed in the upper part, in which we could all observe the face of a young woman, whose head and that part of her body which was visible were surrounded by pure white drapery. The head seemed enveloped by several circular bands of this material, which left visible only a small oval portion of the face, a sufficient portion, however, for one to see exactly the eyes, nose, mouth and upper part of the chin.

"The apparition remained visible to everyone for almost a minute. As Mr. Bozzano was pointing out that we saw only a part of the face, we noticed the finger-tips of two hands draw aside the drapery, thus displaying her form more clearly and completely. Before disappearing, the figure bent her head in salutation, and threw us a kiss, the sound of which was distinctly heard by everyone.

"After a few moments of rest, the table began again its automatic movements. Then the curtains parted once more, as though they had been opened from within by two hands, leaving an ample space in which was seen the figure of a man with large head and strong shoulders, surrounded also by white drapery. The head was enveloped in such a manner that through the light fabric one could see the pink color of the face, the outlines of the nose, cheekbones, and chin. Bozzano and Morselli declared they had noticed, also, a heavy beard upon the chin. This man's face remained visible for a minute, at least.

"It leaned toward us several times, and before withdrawing, sent us several loud kisses, accompanied by expressive movements of the head.

"When the curtains were drawn again we heard hands clapping inside the cabinet.

"At this moment, we also heard Eusapia's voice, calling Professor Morselli in a plaintive tone. He went into the cabinet and found her in the same position in which she had been fastened. The medium in a trance, with evident signs of suffering, was complaining that her wrists were painfully bound. The professor finally loosened her wrists with much difficulty, because of the many complicated knots. Mme. Paladino then remained fastened only by feet and waist.

"Signor Bozzano noticed that the professor, being seated directly beneath the chandelier, was obliged, when watching the medium, to shade his eyes from the light coming from above. He asked Signor Avel-lino, therefore, kindly to give his place to the professor. This was done, so that Dr. Morselli occupied the chair of Mr. Avellino.

"When everyone was in his place, it was observed almost immediately, that the piano lid rose and fell automatically, causing a certain sound.

"Almost at the same time, we became aware of the figure of a young woman in front of the curtain at the right, resembling somewhat the one of whom we have spoken above. The apparition nodded her head several times, bowing, as though in greeting to us. Finally she vanished. Oh this occasion, we were all struck by a new fact, rather important for those readers who will not hesitate to accuse us of hallucination.
