"What does she do?" asked Cameron. "What is her 'phase,' as you call it?" "It must be confessed that most of her phases are of the poltergeist variety, but they are astounding. She produces the movement of mandolins, chairs, sofas, and small tables without contact (at least, such is the consensus of opinion of nearly a score of the best-known scientists of France and Italy), and also materializes hands and arms. There is vastly more than the poltergeist in her, that is evident; for she has conquered every critic with her miracles. Take, for instance, Lombroso's conversion, a fairly typical case. He was not only sceptical of spirit phenomena, but up to 1888 was openly contemptuous of those who believed in them. However, in an article called 'The Influence of Civilization upon Genius,' published in 1888, he made this admission: '_Twenty or thirty years are enough to make the whole world admire a discovery which was treated as madness at the moment when it was made.... Who knows whether my friends and I who laugh at spiritualism are not in error, just like hypnotized persons, or like lunatics; being in the dark as regards the truth, we laugh at those who are not in the same condition._'" "True enough," said Fowler. "The man who has made no study of these phenomena is like one color-blind: he has never seen a landscape." "It was this candid statement by Lombroso that moved Professor Chiaia, a friend of Eusapia's, to write the great alienist a letter which was in effect a challenge. After recounting a score or two of the wonderful doings of Paladino, whom he had studied carefully, he ended in this amusing fashion: 'Now you see my challenge. If you have not written the paragraph cited above simply for the fun of writing it, if you have the true love for science, if you are without prejudices--you, the first alienist of Italy--please take the field. When you can afford a week's vacation, indicate a place where we can meet. Four gentlemen will be our seconds: you will choose two, and I will bring the other two.... If the experiment does not succeed, you will consider me but as a man suffering from hallucination, who longs to be cured of his extravagances.... If success crowns our efforts, your loyalty ... will attest the reality of these mysterious phenomena and promise to investigate their causes.'" "I hope Lombroso was man enough to accept the challenge," said Cameron. "Nothing could be fairer than the spook-man's offer."
