Sir William Crookes has given to the world a very interesting account of his work in weighing mediums, before and during materialization. He always found that a great decrease in weight took place during the materializations, proving how enormous is the drain on the strength of the medium. Such evidence is most valuable, as coming from our greatest chemist. On this particular night I had no doubt as to the genuineness of the medium. Had she been a fraud she would have stopped the séance at once, on seeing how annoyed Lady Caithness was. She had every reason to conciliate her, and was greatly distressed to hear that her services would no longer be required. The troublesome spirits followed her into the next room, but gradually subsided as we succeeded in bringing the woman back out of her trance. I used to go very often to the theater at Nice with Lady Caithness. She had her own box, and often invited Don Carlos of Spain, and other distinguished personages, to accompany her. One night we went to hear the incomparable Judic. We were only a party of three, the third being Prince Valori. The Prince was then a man past middle age. He suggested a magnificent ruin, retaining as he did the battered remains of great good looks, and it was plain to see that his valet was exceedingly skillful. He possessed also a European reputation for heiress hunting, but to the day of his death he never succeeded in catching one, though it was said he had pursued his quarry in all parts of the world. Perhaps the figure he placed upon his ancient lineage and his personal charm was too high; perhaps he had begun his quest too late in life, though the position of a widowed Princess Valori would certainly not have been without attraction. I attributed his single blessedness to quite a different cause. That night, whilst my attention was fixed on the stage, I became dimly aware that some one had entered our box, but until the song was over I did not turn round to look who it was. We always had visitors coming and going. When at last I did glance round I saw nothing remarkable. Only a man in fancy dress seated behind Valori, a man whom I had never seen before. At that period Nice went mad during the winter season. The most extravagant amusements were entered into with a wild zest, by the very cosmopolitan society of extremely wealthy people. There were fancy dress balls every night somewhere, and no one thought it strange to see bands of revelers in fancy costume walking about the streets and thronging the cafés at all hours of the night.
