And what is still more remarkable/ added the professor, 'if you give him an illustrated paper he sees blue and red flames radiating from the printed pictures taken from photographs of living individuals, but never from fancy drawings or engravings which have not been photographed from the living subjects in the first instance.'

A further phenomenon and final marvel in this order of ideas was at more than one sitting presented in the same subject. He was thrown into slumber, and a circlet of magnetised iron was placed round his head and forehead. 'In that magnetised head cap,' said Dr. Luys,' are stored up the thoughts and ideas of a patient who had been the subject of hallucinations of persecution and of black misery. You see that Mervel is now happy and contented enough, but if I now put this magnetised coronet on his head, he will become impregnated with those influences and that order of. thought.' This was done, and very quickly his features became haggard, his expression that of melancholy and fear; presently he struggled, with horror and fright depicted in his face, to escape from imaginary persecutors. 'They are following me,' he cried out; ' I can't get away from them, they are torturing me,' and he endeavoured vainly to escape. Presently the circlet was taken from his forehead, he was told to be calm, and soothed and sent again into profound sleep, then told that he was to awake forgetting all that had happened and to pass a happy day and be very well.

He did awake with a dazed look for a short time, and presently said, smilingly, in answer to questions, that he was feeling well, that he did not remember that anything had happened, and that he was going to have a quiet, pleasant day. Dr. Lutaud, who was present with me at this performance in the wards, wickedly observed to Dr. Luys that this newly-found power of storing up habits of mind and thoughts in a magnetic frontal might have some very convenient uses, especially as this set of ideas had already been stored for six months in this particular apparatus apparently not by any means exhausted by use, and was capable of application within a period of time of which experience had not yet prescribed any limits. It was almost too much for our gravity when Dr. Luys seriously replied that no doubt it was so and might be made very useful,' and that he was using such crowns with good therapeutic effects on his patients. Dr. Lutaud observed that a husband about to lose a beloved wife might store up in such a circlet her affectionate thoughts and good disposition, and might on marrying again infuse these delightful qualities into the brain of his second wife. To this, also, Dr. Luys assented.

These were the leading phenomena presented in connection with the magnetic susceptibilities and perceptions of the hyp-notised subject. They were repeated on other subjects, Clarice, and later on, in my own apartments, Jeanne, a celebrated subject of Luys's lectures, reproduced them to perfection. Figs. 13 and 14 are reproductions of two photographs, which Dr. Luys handed to me as illustrative of the above phenomena of attraction and repulsion of the negative and the positive poles of the magnet and of the red and blue flames issuing from them. He showed me also a portfolio of drawings for future publication, in which Mervel in somnambulistic condition had drawn the coloured flames which he saw issuing from magnets, radiating from. the features of Dr. Luys himself and of various patients, and playing around the different parts of electro-magnetic apparatus. At a later stage Mervel was good enough (always in his somnambulised state) to favour me with a portrait of the flames which he saw radiating from my eyes and nose and ears.

It is an interesting though far from artistic document, which I may reproduce a little later on, when I come to relate the counter-experiments by which I easily demonstrated, in the presence of Dr. Lutaud, Dr. Sajous, M. Cremiere, Dr. Olivier, and others, that the whole of these phenomena in all of these patients and subjects were, as might have been expected, frauds, impostures, and simulation, originating, no doubt, in suggestions made to them, lectures given before them, documents communicated to them, and verbal conspiracies hatched in the waiting -room, carried out in the wards and cleverly worked up by practice to an extraordinary degree of perfection. So wonderfully dramatic were the attitudes and expressions, so graphic, although monotonously similar, were the expressions displayed, so mixed and interwoven were the really hysteric, cataleptic, and somnambulistic conditions presented, heightened and combined by conscious fraud, that it was difficult not to be startled by the extraordinary series of performances shown, and almost impossible at first to divide the basis of reality from the huge superstructure of histrionic fraud and impudent imposture.

I may say at once, however, that I succeeded in all of these subjects, and before the same witnesses, and on the same subjects, in reproducing all the phenomena by methods which were quite incompatible with any truthfulness or reality in the acts or in the explanations given of them; but before proceeding to this part of the story, I will summarise another series of phenomena showed to me by Dr. Lays, including some which were shown to me under his auspices by Colonel Rochas d'Aiglun on a specially 'susceptible' subject brought to the wards for the purpose. These Were the so-called emotional and psychical conditions, transfer of thought, transfer of sensations by contact and at a distance, the communication by contact from patient to patient of diseased conditions of body and of mind, the production of drunkenness in a patient by applying a small sealed tube containing alcohol to the skin, the transfer of that drunkenness to another patient by contact of the hands, the vibrations, as Dr. Luys explained, being probably-transferred from body to body by such contact, the production of hallucinations and visions by skin contact with a tube containing medicinal substances, the pro-duction of anaesthesia in the patient, and the transfer of her sensibility to the air surrounding her in different planes and for given distances, the transfer of her sensi-bility to a glass of water held in her hand, and similarly to a wax doll - such sensations, so transferred, being re-induced in the patient when the glass of water or the figure was stroked, pinched, pricked, or otherwise tickled or tortured at a distance from her, and in positions where it was understood that they could not be seen, and that she was unaware of what was being done.
