Although I did not think that I was dead, I still perceived quite clearly that I was soon to die. This brought me back to the consideration of Haddon's proceedings. I looked into his mind, and saw that he was afraid of cutting a branch of the portal vein. My attention was distracted from details by the curious changes going on in his mind. His consciousness was like the quivering little spot of light which is thrown by the mirror of a galvanometer. His thoughts ran under it like a stream, some through the focus bright and distinct, some shadowy in the half-light of the edge. Just now the little glow was steady; but the least movement on Mowbray's part, the slightest sound from outside, even a faint difference in the slow movement of the living flesh he was cutting, set the light-spot shivering and spinning. A new sense-impression came rushing up through the flow of thoughts; and lo! the light-spot jerked away towards it, swifter than a frightened fish. It was wonderful to think that upon that unstable, fitful thing depended all the complex motions of the man; that for the next five minutes, therefore, my life hung upon its movements. And he was growing more and more nervous in his work. It was as if a little picture of a cut vein grew brighter, and struggled to oust from his brain another picture of a cut falling short of the mark. He was afraid: his dread of cutting too little was battling with his dread of cutting too far. Then, suddenly, like an escape of water from under a lock-gate, a great uprush of horrible realisation set all his thoughts swirling, and simultaneously I perceived that the vein was cut. He started back with a hoarse exclamation, and I saw the brown-purple blood gather in a swift bead, and run trickling. He was horrified. He pitched the red-stained scalpel on to the octagonal table; and instantly both doctors flung themselves upon me, making hasty and ill-conceived efforts to remedy the disaster. "Ice!" said Mowbray, gasping. But I knew that I was killed, though my body still clung to me.
