"I was in high spirits when I went to visit my Amelia that evening, and I told her confidently that before the end of the year I expected to gain the gold medal of the Royal Society. The dear girl was pleased at my glowing prospects, and gave me every assurance of the delight with which she hailed the probability of our approaching union. "Next day I began my experiments afresh in my new quarters. I bolted myself into the laboratory, and set to work with renewed vigour. I was experimenting upon an injured dog, and I placed a large bottle of pausodyne beside me as I administered the drug to his nostrils. The rising fumes seemed to affect my head more than usual in that confined space, and I tottered a little as I worked. My arm grew weaker, and at last fell powerless to my side. As it fell it knocked down the large bottle of pausodyne, and I saw the liquid spreading over the floor. That was almost the last thing that I knew. I staggered toward the door, but did not reach it; and then I remember nothing more for a considerable period." He wiped his forehead with his sleeve--he had no handkerchief--and then proceeded. "When I woke up again the effects of the pausodyne had worn themselves out, and I felt that I must have remained unconscious for at least a week or a fortnight. My candle had gone out, and I could not find my tinder-box. I rose up slowly and with difficulty, for the air of the room was close and filled with fumes, and made my way in the dark towards the door. To my surprise, the bolt was so stiff with rust that it would hardly move. I opened it after a struggle, and found myself in the passage. Groping my way towards the trap-door of the cellar, I felt it was obstructed by some heavy body. With an immense effort, for my strength seemed but feeble, I pushed it up, and discovered that a heap of sea-coals lay on top of it. I extricated myself into the cellar, and there a fresh surprise awaited me. A new entrance had been made into the front, so that I walked out at once upon the open road, instead of up the stairs into the kitchen. Looking up at the exterior of my house, my brain reeled with bewilderment when I saw that it had disappeared almost entirely, and that a different porch and wholly unfamiliar windows occupied its facade. I must have slept far longer than I at first imagined--perhaps a whole year or more. A vague terror prevented me from walking up the steps of my own home. Possibly my brother, thinking me dead, might have sold the lease; possibly some stranger might resent my intrusion into the house that was now his own. At any rate, I thought it safer to walk into the road. I would go towards London, to my brother's house in St. Mary le Bone. I turned into the Hampstead Road, and directed my steps thitherward.
