Professor Oliver Lodge in his turn invited Mrs Piper to come and give sittings at his home in Liverpool. She went, and remained from 18th December to 27th December 1889. During this time she gave at least two sittings a day, which fatigued her much. Professor Lodge gave up for the time all other work to study her. He enumerates at length all the precautions he took to prevent fraud. He also declares that Mrs Piper, who was perfectly aware of the watch kept upon her, never showed the least displeasure, and thought it quite natural. He wondered whether, by chance, she might not have among her luggage some book containing biographies of men of the day, and asked permission to look through her trunks. She consented with the best possible grace. But Professor Lodge found nothing suspicious. Mrs Piper also handed over to be read the greater number of the letters she received; they were not numerous; about three a week. The servants in the house were all new; they knew nothing of the family's private affairs, and thus could not inform the medium about them. Besides, Mrs Piper never tried to question them. Mrs Lodge, who was very sceptical at first, kept guard over her own speech, so as not to give any scraps of information. The family Bible (on the first pages of which, according to custom, memorable events are recorded) and the photographic albums were locked away. Professor Lodge, like the others, presented most of his sitters under false names. Finally, he affirms that Mrs Piper's attitude never justified the least suspicion; she was dignified, reserved, and not in any way indiscreet. In short, during the fifteen years the experiments have continued, all the suggestions made by sceptical and sometimes violent objectors have been kept in view, that the fraud might be discovered, if fraud there were. All has been in vain. The explanation of the phenomena must consequently be sought elsewhere. As for the trance itself, all those who have seen it agree in saying that it is genuine and in no way feigned. The hypothesis of fraud being disposed of, recourse has been had to another, which it has also become necessary to abandon--that of the reading of muscular movements. It appears that the thought-readers who exhibit themselves on the platform accomplish their wonderful feats by interpreting, with remarkable intelligence, sharpened by long practice, the unconscious movements of the persons whose wrists they are holding.
