As he said this, Sir William turned towards the end of the room where his assistant was busy bending over one of the machines. The man, with the large hairless face, was pale, and his fingers were shaking, as they moved about among the screws and wires. He did not look up as Gouldesbrough paid him this just tribute, though every one of the spectators turned towards him at the mention of his name. Truth to tell, Mr. Wilson Guest was, for the first time for many years, absolutely bereft of all alcoholic liquor since the night before. For the first time in their partnership Gouldesbrough had insisted upon Guest's absolute abstention. He had never done such a thing before, as he pointed out to his friend, but on this day he said his decision was final and he meant to be obeyed. The frenzied entreaties of the poor wretch about mid-day, his miserable abasement and self-surrender, as he wept for his poison, were useless alike. He had been forced to yield, and at this moment he was suffering something like torture. It was indeed only by the greatest effort of his weakened will that he could attend to the mechanical duties of adjusting the sensitive machines for the demonstration which was to follow. "I cannot suppose that any of you here are now unaware of the nature of my experiments and discovery. It has been ventilated in the press so largely during the last few days, and Mr. Donald Megbie has written such a lucid account of the influence which he believes the discovery will have upon modern life, that I am sure you all realize something of the nature of what I am about to show you. "To put it very plainly, I am going to show you how thought can be collected in the form of vibrations, in the form of fluid electric current, and collected directly from the brain of the thinker as he thinks. "I am further going to demonstrate to you how this current can be transformed into a visible, living and actual representation of the thoughts of the thinker." He stopped for a moment, and there was a little murmur from his guests. Then he went on. "Before proceeding to actual experiment, it is necessary that I should give you some account of the means by which I have achieved such marvellous results. I do not propose to do this in extremely technical language, for were I to do so, a large portion of those here this afternoon would not be able to follow me. I shall proceed to explain in words, which I think most of you will understand. "My illustrious _confrères_ in Science will follow me and understand the technical aspect of what I am going to put into very plain language, and to them especially I would say that, after the actual experiment has been conducted, I shall beg them to examine my apparatus and to go into the matter with me from a purely scientific aspect. "And now, ladies and gentlemen, let me begin.
