Signs of drunkenness were said to be caused by a small corked bottle of brandy, and the nature of a cat by a corked bottle of valerian. Patients also saw beautiful blue flames about the north pole of a magnet and distasteful red flames about the south pole; while by means of a magnet it was said that the symptoms of illness of a sick patient might be transferred to a well person also in the hypnotic state, but of course on awaking the well person at once threw off sickness that had been transferred, but the sick person was permanently relieved. These experiments are cited in some recent books on hypnotism, apparently with faith. The following counter experiments will therefore be read with interest. Dr. Hart gives a full account of his investigations in the Nineteenth Century. Dr. Luys gave Dr. Hart some demonstrations, which the latter describes as follows: “A tube containing ten drachms of cognac were placed at a certain point on the subject’s neck, which Dr. Luys said was the seat of the great nerve plexuses. The effect on Marguerite was very rapid and marked; she began to move her lips and to swallow; the expression of her face changed, and she asked, ‘What have you been giving me to drink? I am quite giddy.’ At first she had a stupid and troubled look; then she began to get gay. ‘I am ashamed of myself,’ she said; ‘I feel quite tipsy,’ and after passing through some of the phases of lively inebriety she began to fall from the chair, and was with difficulty prevented from sprawling on the floor. She was uncomfortable, and seemed on the point of vomiting, but this was stopped, and she was calmed.” Another patient gave all the signs of imagining himself transformed into a cat when a small corked bottle of valerian was placed on his neck. In the presence of a number of distinguished doctors in Paris, Dr. Hart tried a series of experiments in which by his conversation he gave the patient no clue to exactly what drug he was using, in order that if the patient was simulating he would not know what to simulate. Marguerite was the subject of several of these experiments, one of which is described as follows:
