Repeated measurements of emotion by means of the psycho-galvanic reflex in connection with Jung's word association experiment gave correlation coefficients of about + ·65 between different groups of experiments for the same individual, and of about + ·15 between the results for one

individual and those for another. Individual differences are therefore well brought out by this method; though in the present experiment the twenty words from Jung's list, which had previously been shown to arouse the greatest affective tone in all individuals, were omitted, their places being taken by more indifferent words. In conclusion, the author makes some interesting suggestions as to the bearing of his results on possible future research on alternating personalities, mediumistic trance conditions, hypnosis, etc.
