When the clock struck nine, a dead silence fell upon the Theatre; not a breath was heard; not a cough; not the rustle of a dress. Their faces were pale with expectancy; their lips were parted; their very breathing seemed arrested. Then the President and the Council walked in and took their places. "Ladies and Gentlemen," said the President shortly, "the learned Professor will himself communicate to you the subject and title of his Paper, and we may be certain beforehand that this subject and matter will adorn the motto of the Society--_Illustrous commoda vitæ._" Then Dr. Schwarzbaum stood at the table before them all, and looked round the room. Lady Mildred glanced at the young man, Harry Linister. He was staring at the German like the rest, speechless. She sighed. Women did not in those days like love-making to be forgotten or interrupted by anything, certainly not by science. The learned German carried a small bundle of papers, which he laid on the table. He carefully and slowly adjusted his spectacles. Then he drew from his pocket a small leather case. Then he looked round the room and smiled. That is to say, his lips were covered with a full beard, so that the sweetness of the smile was mostly lost; but it was observed under and behind the beard. The mere ghost of a smile; yet a benevolent ghost. The Lecturer began, somewhat in copy-book fashion, to remind his audience that everything in Nature is born, grows slowly to maturity, enjoys a brief period of full force and strength, then decays, and finally dies. The tree of life is first a green sapling, and last a white and leafless trunk. He expatiated at some length on the growth of the young life. He pointed out that methods had been discovered to hinder that growth, turn it into unnatural forms, even to stop and destroy it altogether. He showed how the body is gradually strengthened in all its parts; he showed, for his unscientific hearers, how the various parts of the structure assume strength. All this was familiar to most of his audience. Next he proceeded to dwell upon the period of full maturity of bodily and mental strength, which, in a man, should last from twenty-five to sixty, and even beyond that time. The decay of the bodily, and even of the mental organs, may have already set in, even when mind and body seem the most vigorous. At this period of the discussion most of the audience were beginning to flag in their attention. Was such a gathering as this assembled only to hear a discussion on the growth and decay of the faculties? But the Director, who knew what was coming, sat bolt upright, expectant. It was strange, the people said afterwards, that no one should have suspected what was coming. There was to be, everybody knew, a great announcement. That was certain. Destruction, Locomotion, Food, Transmission of Thought, Substitution of Speech for Writing--all these things, as has been seen, had been suggested. But no one even guessed the real nature of the Discovery.
