I must have stared upon it for near half a minute, sunk as I was in the mere stupidity of wonder, before terror woke up in my breast as sudden and startling as the crash of cymbals; and bounding from my bed I rushed to the mirror. At the sight that met my eyes, my blood was changed into something exquisitely thin and icy. Yes, I had gone to bed Henry Jekyll, I had awakened Edward Hyde. How was this to be explained? I asked myself; and then, with another bound of terror--how was it to be remedied? It was well on in the morning; the servants were up; all my drugs were in the cabinet--a long journey down two pairs of stairs, through the back passage, across the open court and through the anatomical theatre, from where I was then standing horror-struck. It might indeed be possible to cover my face; but of what use was that, when I was unable to conceal the alteration in my stature? And then with an overpowering sweetness of relief, it came back upon my mind that the servants were already used to the coming and going of my second self. I had soon dressed, as well as I was able, in clothes of my own size: had soon passed through the house, where Bradshaw stared and drew back at seeing Mr. Hyde at such an hour and in such a strange array; and ten minutes later, Dr. Jekyll had returned to his own shape and was sitting down, with a darkened brow, to make a feint of breakfasting.
Small indeed was my appetite. This inexplicable incident, this reversal of my previous experience, seemed, like the Babylonian finger on the wall, to be spelling out the letters of my judgment; and I began to reflect more seriously than ever before on the issues and possibilities of my double existence. That part of me which I had the power of projecting, had lately been much exercised and nourished; it had seemed to me of late as though the body of Edward Hyde had grown in stature, as though (when I wore that form) I were conscious of a more generous tide of blood; and I began to spy a danger that, if this were much prolonged, the balance of my nature might be permanently overthrown, the power of voluntary change be forfeited, and the character of Edward Hyde become irrevocably mine. The power of the drug had not been always equally displayed. Once, very early in my career, it had totally failed me; since then I had been obliged on more than one occasion to double, and once, with infinite risk of death, to treble the amount; and these rare uncertainties had cast hitherto the sole shadow on my contentment. Now, however, and in the light of that morning's accident, I was led to remark that whereas, in the beginning, the difficulty had been to throw off the body of Jekyll, it had of late gradually but decidedly transferred itself to the other side. All things therefore seemed to point to this; that I was slowly losing hold of my original and better self, and becoming slowly incorporated with my second and worse.
Between these two, I now felt I had to choose. My two natures had memory in common, but all other faculties were most unequally shared between them. Jekyll (who was composite) now with the most sensitive apprehensions, now with a greedy gusto, projected and shared in the pleasures and adventures of Hyde; but Hyde was indifferent to Jekyll, or but remembered him as the mountain bandit remembers the cavern in which he conceals himself from pursuit. Jekyll had more than a father's interest; Hyde had more than a son's indifference. To cast in my lot with Jekyll, was to die to those appetites which I had long secretly indulged and had of late begun to pamper. To cast it in with Hyde, was to die to a thousand interests and aspirations, and to become, at a blow and forever, despised and friendless. The bargain might appear unequal; but there was still another consideration in the scales; for while Jekyll would suffer smartingly in the fires of abstinence, Hyde would be not even conscious of all that he had lost. Strange as my circumstances were, the terms of this debate are as old and commonplace as man; much the same inducements and alarms cast the die for any tempted and trembling sinner; and it fell out with me, as it falls with so vast a majority of my fellows, that I chose the better part and was found wanting in the strength to keep to it.
