As soon as he had finished his calculations he took the paper in his hands, and went out with it to make two calls on scientific acquaintances. The first man he called upon was that distinguished specialist, Professor Linklight, one of the greatest authorities of his own day on all questions of molecular physics. Poor man! he is almost forgotten now, for he died ten years ago; and his scientific reputation was, after all, of that flashy sort which bases itself chiefly upon giving good dinners to leading fellows of the Royal Society. But fifteen years ago Professor Linklight, with his cut-and-dried dogmatic notions, and his narrow technical accuracy, was universally considered the principal physical philosopher in all England. To him, then, Arthur Greatrex--a far deeper and clearer thinker--took in all humility the first manuscript of his marvellous discovery; not to ask him whether it was true or not, but to find out whether it was physical science at all or pure insanity. The professor received him kindly; and when Arthur, who had of course his own reasons for attempting a little modest concealment, asked him to look over a friend's paper for him, with a view to its presentation to the Royal Society, he cheerfully promised to do his best. "Though you will admit, my dear Mr. Greatrex," he said with his blandest smile, "that your friend's manuscript certainly does not err on the side of excessive brevity." From Linklight's, Arthur walked on tremulously to the house of another great scientific magnate, Dr. Warminster, of being the first living authority on the treatment of the insane in the United Kingdom. Before Dr. Warminster, Arthur made no attempt to conceal his apprehensions. He told out all his symptoms and fears without reserve, even exaggerating them a little, as a man is prone to do through over-anxiety not to put too favourable a face upon his own ailments. Dr. Warminster listened attentively and with a gathering interest to all that Arthur told him, and at the end of his account he shook his head gloomily, and answered in a very grave and sympathetic tone.
