"I was then conducting my experiments upon living animals, and especially upon the extirpation of certain painful internal diseases to which they are subject. I had a number of suffering cats in my laboratory, which I had treated with pausodyne, and stretched out on boards for the purpose of removing the tumours with which they were afflicted. I had no doubt that in this manner, while directly benefiting the animal creation, I should indirectly obtain the necessary skill to operate successfully upon human beings in similar circumstances. Already I had completely cured several cats without any pain whatsoever, and I was anxious to proceed to the human subject. Walking one morning in the Strand, I found a beggar woman outside a gin-shop, quite drunk, with a small, ill-clad child by her side, suffering the most excruciating torments from a perfectly remediable cause. I induced the mother to accompany me to my laboratory, and there I treated the poor little creature with pausodyne, and began to operate upon her with perfect confidence of success.
"Unhappily, my laboratory had excited the suspicion of many ill-disposed persons among the low mob of the neighbourhood. It was whispered abroad that I was what they called a vivisectionist; and these people, who would willingly have attended a bull-baiting or a prize fight, found themselves of a sudden wondrous humane when scientific procedure was under consideration. Besides, I had made myself unpopular by receiving visits from my friend Dr. Priestley, whose religious opinions were not satisfactory to the strict orthodoxy of St. Giles's. I was rumoured to be a philosopher, a torturer of live animals, and an atheist. Whether the former accusation were true or not, let others decide; the two latter, heaven be my witness, were wholly unfounded. However, when the neighbouring rabble saw a drunken woman with a little girl entering my door, a report got abroad at once that I was going to vivisect a Christian child. The mob soon collected in force, and broke into the laboratory. At that moment I was engaged, with my assistant, in operating upon the girl, while several cats, all completely anæstheticised, were bound down on the boards around, awaiting the healing of their wounds after the removal of tumours. At the sight of such apparent tortures the people grew wild with rage, and happening in their transports to fling down a large bottle of the anegeiric, or reviving mixture, the child and the animals all at once recovered consciousness, and began of course to writhe and scream with acute pain. I need not describe to you the scene that ensued. My laboratory was wrecked, my assistant severely injured, and I myself barely escaped with my life.
"After this contretemps I determined to be more cautious. I took the lease of a new house at Hampstead, and in the garden I determined to build myself a subterranean laboratory where I might be absolutely free from intrusion. I hired some labourers from Bath for this purpose, and I explained to them the nature of my wishes, and the absolute necessity of secrecy. A high wall surrounded the garden, and here the workmen worked securely and unseen. I concealed my design even from my dear brother—whose grandson or great-grandson I suppose you must be—and when the building was finished, I sent my men back to Bath, with strict injunctions never to mention the matter to any one. A trap-door in the cellar, artfully concealed, gave access to the passage; a large oak portal, bound with iron, shut me securely in; and my air supply was obtained by means of pipes communicating through blank spaces in the brick wall of the garden with the outer atmosphere. Every arrangement for concealment was perfect; and I resolved in future, till my results were perfectly established, that I would dispense with the aid of an assistant.
"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 façade. 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.
"Again, another surprise began to affect me with a horrible and ill-defined sense of awe. Not a single object that I saw was really familiar to me. I recognized that I was in the Hampstead Road, but it was not the Hampstead Road which I used to know before my fatal experiments. The houses were far more numerous, the trees were bigger and older. A year, nay, even a few years would not have sufficed for such a change. I began to fear that I had slept away a whole decade.
"It was early morning, and few people were yet abroad. But the costume of those whom I met seemed strange and fantastic to me. Moreover, I noticed that they all turned and looked after me with evident surprise, as though my dress caused them quite as much astonishment as theirs caused me. I was quietly attired in my snuff-coloured suit of small-clothes, with silk stockings and simple buckle shoes, and I had of course no hat; but I gathered that my appearance caused universal amazement and concern, far more than could be justified by the mere accidental absence of head-gear. A dread began to oppress me that I might actually have slept out my whole age and generation. Was my Amelia alive? and if so, would she be still the same Amelia I had known a week or two before? Should I find her an aged woman, still cherishing a reminiscence of her former love; or might she herself perhaps be dead and forgotten, while I remained, alone and solitary, in a world which knew me not?
"I walked along unmolested, but with reeling brain, through streets more and more unfamiliar, till I came near the St. Mary le Bone Road. There, as I hesitated a little and staggered at the crossing, a man in a curious suit of dark blue clothes, with a grotesque felt helmet on his head, whom I afterwards found to be a constable, came up and touched me on the shoulder.
