"These particular sittings at Turin made a great sensation in Italy. They were under the direction of Drs. Herlitzka, Foa, and Aggazzotti, assistants to Professor Mosso, of the University of Turin. Dr. Pio Foa, Professor of Pathologic Anatomy, was also present during one seance. The conditions were all of the experimenters' own contriving. They were young men and had been companion workers in science for many years, and were accustomed to laboratory work. They all came to this experiment perfectly sure that no mediumistic phenomena could endure the light of science. At the end of their three sittings they manfully said: '_Now that we are persuaded of the authenticity of the phenomena_, we feel it our duty to state the fact publicly in our turn, and to proclaim that the few pioneers in this branch of biology (destined to become one of the most important) generally saw and observed correctly.... We hope that our words may serve to stimulate some of these colleagues to study personally and attentively this group of interesting and obscure phenomena.' You will note they relate their tests, not to theology, but to unexplored biology." "I like the ring of that declaration of theirs," said Harris. "Go on! Come to Hecuba!" "Bottazzi was enormously impressed by this account, which detailed coldly, critically, the most amazing experiments. With ingenuity that would have seemed satanic to Paladino (had she known of it), Foa and Aggazzotti had laid their pipes and provided for every trick. They were confident that nothing genuine could occur, but, as a matter of record, weird performances began at once. Bells were rung, tables shifted, columns of mercury lifted, mandolins played, and small objects were transported quite in the same fashion as the books were handled during our own sittings at your house, Miller--in fact, the doings were much the same in character. A small stand was broken to pieces under the very eyes of the learned doctors, _and hands hit and teeth bit those whom the medium did not like_. Each of the machines for registering movement, though utterly out of reach of Paladino, was operated, and some of these movements were systematically recorded. "It was this care, these scrupulous and cold-blooded tests, that so profoundly affected Bottazzi. These men were his friends. He knew their level-headed and remorseless accuracy. The fact that they considered the whole investigation biologic in character, and that the results of their experiments strengthened their theory of the physiological determinism of the phenomena, added to his eagerness to try for himself." "Wait a moment," said Cameron. "What do you mean by 'physiological determinism'?" "He means that the phenomena began and ended in the psychic's organism." "Do you intend to convey that they considered the medium dishonest?" "Oh no. Merely that they did not relate the phenomena to the intervention of the spirits of the dead." "Oh!" gasped Mrs. Cameron.
