the cult and would be fuller still if everyone had his due. It was a violent but not an effective speech. Evidently the great man was rattled. He realised that there was a case to be met and that he had not provided himself with the material wherewith to meet it. Therefore he had taken refuge in angry words and sweeping assertions which can only be safely made when there is no antagonist present to take advantage of them. The Spiritualists seemed more amused than angry. The materialists fidgeted uneasily in their seats. Then James Smith rose for his last innings. He wore a mischievous smile. There was quiet menace in his whole bearing. He must ask, he said, for a more scientific attitude from his illustrious opponent. It was an extraordinary fact that many scientific men, when their passions and prejudices were excited, showed a ludicrous disregard for all their own tenets. Of these tenets there was none more rigid than that a subject should be examined before it was condemned. We have seen of late years, in such matters as wireless or heavier-than-air machines, that the most unlikely things may come to pass. It is most dangerous to say _a priori_ that a thing is impossible. Yet this was the error into which Professor Challenger had fallen. He had used the fame which he had rightly won in subjects which he had mastered in order to cast discredit upon a subject which he had not mastered. The fact that a man was a great physiologist and physicist did not in itself make him an authority upon psychic science.
