"Sir," he said, "I know, none better perhaps in this room, of the marvellous series of triumphs which have led you to this supreme moment. I know how absolutely and utterly true all you have told us is, and I know that we are going to witness your triumph." He turned round to the people behind him. "We are going to see," he said, "the human soul laid bare for the first time in the history of the world." Then he turned once more to Sir William, and his voice, though still full of almost uncontrollable emotion, became deep and stern. "Sir William Gouldesbrough," he said, "I have to salute you as the foremost scientist of all time, greater than Newton, greater than Darwin, greater than us all. And I pray to God that you have used the great talent He has given you in a worthy way, and I pray that, if you have done this, you will always continue to do so; for surely it is only for some special reason that God has allowed you this mastery." He ceased, and there was rustle and hum of movement among all the people, as this patriarch lifted his voice with almost a note of warning and menace in it. It was all so unusual, so unexpected--why did this strange prophetic note come into the proceedings? What was hidden in the old man's brain? Every one felt the presence, the unseen presence of deep waters and hidden things. Marjorie Poole had bowed her head, she was absolutely motionless. There was a tension in the air. Sir William Gouldesbrough's head was bowed also, as he listened with courteous deference to the words of one whose name had been chief and most honoured in the scientific world for so many years. Those who watched him remarked afterwards that he seemed to be stricken into stone for a moment, as words which were almost a veiled accusation pealed out into the great room. Then they saw Sir William once more himself in a swift moment. His eyes were bright and there was a look of triumph on his face. "I thank you, Lord Malvin," he said, in a voice which was arrogant and keen, "I thank you for your congratulations, your belief, and for your hopes for me; and now my lord, ladies, and gentlemen, shall we not proceed to the actual demonstration? "I am going to ask that one of you come down from your seat and allow me to place the cap upon your head. I shall then darken the laboratory, and the actual thoughts of the lady or gentleman who submits herself or himself to the experiment will be thrown upon the screen." There was a dead silence now, but most of the people there looked at each other in doubt and fear.
