“To sum up, the case of H. B. has an appearance which is, frankly speaking, spiritistic; but it is not possible to consider as certain, or even as probable, the pretensions manifested by this interesting personification.” _SERIES B_ A. RAPS I propose gathering together, for the first part of this series, a few interesting things scattered here and there among the notes before me. On one occasion Chappe dictated by means of raps without contact—in broad daylight—that 760 copies of a work of Dr. Maxwell’s had been sold. Four days later, in the same manner, he said that 958 copies of the said work had been sold; incorrect information as the following proves: the day after the seance in which Chappe had announced the sale of 958 copies, Dr. Maxwell received a letter from the publisher of the work in question telling him that 800 copies had left him, including the press service. * * * * * “We had some good phenomena on Tuesday afternoon,” writes Dr. Maxwell. “I was talking to M. Meurice about my bibliographical researches, and of the best plan to adopt for the analytical indexes. A small mahogany table was near us, one leg of the table was touching a rug on which M. Meurice was sitting. Raps resounded on the table; Chappe’s signal was given, followed by some advice concerning the subject of our conversation. Telekinetic phenomena were also forthcoming—the table gliding towards us and then away from us according to request, travelling a distance of from three to five inches. “Then I tried an experiment, one I have been wishing to try for some time: I bade M. Meurice sit in an armchair and lie perfectly still. I placed his arm at about one foot from the table, and told him to _fancy_ he lifted his arm and struck the table, without, of course, making the slightest movement. “We obtained some excellent raps in this way. This is a fine experiment, for it shows clearly the production of raps by the will—the direct, conscious and personal will. “We tried three series of experiments; six raps in each series were willed; we received four raps in each, that is to say, 66 per cent. of success. The raps were loud, one was double. The medium nearly fainted after this experiment, but came round quickly, though he has not been well since. “His sensations were: (1) absence of sensation in the arm with which we were experimenting; (2) a kind of breeze issuing from his shoulder. After willing the raps he was never sure of success, he did not feel the wood had been touched. Sensibility appeared to be exteriorised.” * * * * * In another of Dr. Maxwell’s letters we note the following:—
