Nausea and a strong desire for sleep were experienced by the subjects in this series of experiments, as before. The above is a very rapid summary of the report drawn up by Dr. Sydney Alrutz, and read to the Sixth Psychological Congress, which met at Geneva in August 1909. Professor Alrutz also attended the Congress in person, and brought with him one of his instruments, which he desired to try upon some of the members in the presence of a number of psychologists. In several instances these attempts were entirely successful; and Professor Flournoy, editor of the _Archives de Psychologie_, was enabled to say of these experiments: "Professor Alrutz invited me to assist in two seances, in which we experimented upon some of the feminine members of the Congress who desired to try it. The first, in which the subject was Mme. Glika, yielded nothing conclusive. But at the second, at which Professor Alrutz attempted to increase the force by adding two other members of the Congress (strangers who had appeared to him to possess suitable temperaments), it succeeded fully, and I was able to prove conclusively after three trials, and under conditions precluding all possibility of fraud or illusion, that the will of these ladies, concentrated upon a certain material object with a desire to produce a movement in it, ended by producing this movement as if by means of a fluid or an invisible force obeying their mental command." (_Spiritism and Psychology_, p. 291.) So much for the testimony of Professor Flournoy and Professor Alrutz. In view of the facts and the well-known caution of these investigators, we may assuredly take it for granted that there is here no room for doubt, and that the manifestations really took place as recorded.
