Then suddenly his frenzy left him at the voice of a woman shrieking so that it filled the room. He looked up and crouched motionless as he heard and saw the study door closing and heard the patter of feet retreating in panic. Then he looked down and saw the thing that had once been the face of Findlay. For an awful minute he remained kneeling agape. Then he staggered to his feet and stood over Findlay’s body in the glow of the dying fire, like a man awakening from a nightmare. Suddenly he perceived the _bulla_ on his hand, covered with blood and hair, and began to understand what had happened. In a sudden horror he flung the diabolical thing from him. It struck the floor near the cigar cabinet, rolled for a yard or so on its edge, and came to rest in almost the position it had occupied when he had first set eyes on it. To Temple’s excited imagination it seemed to be lying at exactly the same spot, the sole and sufficient cause of Findlay’s death and his own. A SLIP UNDER THE MICROSCOPE Outside the laboratory windows was a watery grey fog, and within a close warmth and the yellow light of the green-shaded gas lamps that stood two to each table down its narrow length. On each table stood a couple of glass jars containing the mangled vestiges of the crayfish, mussels, frogs, and guinea-pigs, upon which the students had been working, and down the side of the room, facing the windows, were shelves bearing bleached dissections in spirit, surmounted by a row of beautifully executed anatomical drawings in white wood frames and overhanging a row of cubical lockers. All the doors of the laboratory were panelled with blackboard, and on these were the half-erased diagrams of the previous day’s work. The laboratory was empty, save for the demonstrator, who sat near the preparation-room door, and silent, save for a low, continuous murmur, and the clicking of the rocker microtome at which he was working. But scattered about the room were traces of numerous students: hand-bags, polished boxes of instruments, in one place a large drawing covered by newspaper, and in another a prettily bound copy of “News from Nowhere,” a book oddly at variance with its surroundings. These things had been put down hastily as the students had arrived and hurried at once to secure their seats in the adjacent lecture-theatre. Deadened by the closed door, the measured accents of the professor sounded as a featureless muttering.
