this is parallel to the experiences revealed by dream investigation (Freud's[41]) must remain undecided, for we have no means of judging how far the effect mentioned can be considered a "repressed" one. From the brusque interruption of the new personality, we may conclude that the presentations concerned were very vivid, with corresponding intensity of expectation. This perhaps was an attempt to overcome a certain maidenly shyness and embarrassment. This event reminds us vividly of the manner in which the dream presents to consciousness, by a more or less transparent symbolism, things one has never said to oneself clearly and openly. We do not know when this dissociation of the new personality occurred, whether it had been slowly prepared in the unconscious, or whether it first occurred in the séance. In any case, this event meant a considerable increase in the extension of the unconscious sphere rendered accessible through the hypnosis. At the same time this event must be regarded as powerfully suggestive in regard to the impression which it made upon the waking consciousness of the patient. For the perception of this unexpected intervention of a new power must inevitably excite a feeling of the strangeness of the automatisms, and would easily suggest the thought that an independent spirit is here making itself known. Hence the intelligible association that she would finally be able to see this spirit. The situation that ensued at the second séance is to be explained by the coincidence of this energising suggestion with the heightened suggestibility conditioned by the darkness. The hypnosis, and with it the series of dissociated presentations, break through to the visual area, and the expression of the unconscious, hitherto purely motor, is made objective, according to the measure of the specific energy of the new system, in the shape of visual images with the character of hallucinations; not as a mere accompanying phenomenon of the word-automatism, but as a substituted function. The explanation of the situation that arose in the first séance, at that time unexpected and inexplicable, is no longer presented in words, but as a descriptive allegorical vision. The sentence "they do not hate one another, but are friends," is expressed in a picture. We often encounter events of this kind in somnambulism. The thinking of somnambulists is given in plastic images which constantly break into this or that sense-sphere and are made objective in hallucinations. The process of reflection sinks into the subconscious; only its end-results arise to consciousness either as presentations vividly tinged by the senses, or directly as hallucinations. In our case the same thing occurred as in the patient whose anæsthetic hand Binet pricked nine times, making her think of the figure 9; or as in Flournoy's[42] Helen Smith, who, when asked during business-hours about certain patterns, suddenly saw the number of days (18) for which they had been lent, at
