I was so far in my reflections when, as I have said, a side-light began to shine upon the subject from the laboratory table. I began to perceive more deeply than it has ever yet been stated, the trembling immateriality, the mist-like transience of this seemingly so solid body in which we walk attired. Certain agents I found to have the power to shake and to pluck back that fleshly vestment, even as a wind might toss the curtains of a pavilion. For two good reasons, I will not enter deeply into this scientific branch of my confession. First, because I have been made to learn that the doom and burthen of our life is bound for ever on man’s shoulders, and when the attempt is made to cast it off, it but returns upon us with more unfamiliar and more awful pressure. Second, because, as my narrative will make, alas! too evident, my discoveries were incomplete. Enough, then, that I not only recognised my natural body for the mere aura and effulgence of certain of the powers that made up my spirit, but managed to compound a drug by which these powers should be dethroned from their supremacy, and a second form and countenance substituted, none the less natural to me because they were the expression, and bore the stamp, of lower elements in my soul.

I hesitated long before I put this theory to to the test of practice. I knew well that I risked death; for any drug that so potently controlled and shook the very fortress of identity, might by the least scruple of an overdose or at the least inopportunity in the moment of exhibition, utterly blot out that immaterial tabernacle which I looked to it to change. But the temptation of a discovery so singular and profound, at last overcame the suggestions of alarm. I had long since prepared my tincture; I purchased at once, from a firm of wholesale chemists, a large quantity of a particular salt which I knew, from my experiments, to be the last ingredient required; and late one accursed night, I compounded the elements, watched them boil and smoke together in the glass, and when the ebullition had subsided, with a strong glow of courage, drank off the potion.

The most racking pangs succeeded: a grinding in the bones, deadly nausea, and a horror of the spirit that cannot be exceeded at the hour of birth or death. Then these agonies began swiftly to subside, and I came to myself as if out of a great sickness. There was something strange in my sensations, something indescribably new and, from its very novelty, incredibly sweet. I felt younger, lighter, happier in body; within I was conscious of a heady recklessness, a current of disordered sensual images running like a mill-race in my fancy, a solution of the bonds of obligation, an unknown but not an innocent freedom of the soul. I knew myself, at the first breath of this new life, to be more wicked, tenfold more wicked, sold a slave to my original evil; and the thought, in that moment, braced and delighted me like wine. I stretched out my hands, exulting in the freshness of these sensations; and in the act, I was suddenly aware that I had lost in stature.

What on earth was he, — man or beast? What did he want with me? I had no weapon, not even a stick. Flight would be madness. At any rate the Thing, whatever it was, lacked the courage to attack me. Setting my teeth hard, I walked straight towards him. I was anxious not to show the fear that seemed chilling my backbone. I pushed through a tangle of tall white-flowered bushes, and saw him twenty paces beyond, looking over his shoulder at me and hesitating. I advanced a step or two, looking steadfastly into his eyes.

“Who are you?” said I.

He tried to meet my gaze. “No!” he said suddenly, and turning went bounding away from me through the undergrowth. Then he turned and stared at me again. His eyes shone brightly out of the dusk under the trees.

My heart was in my mouth; but I felt my only chance was bluff, and walked steadily towards him. He turned again, and vanished into the dusk. Once more I thought I caught the glint of his eyes, and that was all.

For the first time I realised how the lateness of the hour might affect me. The sun had set some minutes since, the swift dusk of the tropics was already fading out of the eastern sky, and a pioneer moth fluttered silently by my head. Unless I would spend the night among the unknown dangers of the mysterious forest, I must hasten back to the enclosure. The thought of a return to that pain-haunted refuge was extremely disagreeable, but still more so was the idea of being overtaken in the open by darkness and all that darkness might conceal. I gave one more look into the blue shadows that had swallowed up this odd creature, and then retraced my way down the slope towards the stream, going as I judged in the direction from which I had come.

I walked eagerly, my mind confused with many things, and presently found myself in a level place among scattered trees. The colourless clearness that comes after the sunset flush was darkling; the blue sky above grew momentarily deeper, and the little stars one by one pierced the attenuated light; the interspaces of the trees, the gaps in the further vegetation, that had been hazy blue in the daylight, grew black and mysterious. I pushed on. The colour vanished from the world. The tree-tops rose against the luminous blue sky in inky silhouette, and all below that outline melted into one formless blackness. Presently the trees grew thinner, and the shrubby undergrowth more abundant. Then there was a desolate space covered with a white sand, and then another expanse of tangled bushes. I did not remember crossing the sand-opening before. I began to be tormented by a faint rustling upon my right hand. I thought at first it was fancy, for whenever I stopped there was silence, save for the evening breeze in the tree-tops. Then when I turned to hurry on again there was an echo to my footsteps.

I turned away from the thickets, keeping to the more open ground, and endeavouring by sudden turns now and then to surprise something in the act of creeping upon me. I saw nothing, and nevertheless my sense of another presence grew steadily. I increased my pace, and after some time came to a slight ridge, crossed it, and turned sharply, regarding it steadfastly from the further side. It came out black and clear-cut against the darkling sky; and presently a shapeless lump heaved up momentarily against the sky-line and vanished again. I felt assured now that my tawny-faced antagonist was stalking me once more; and coupled with that was another unpleasant realisation, that I had lost my way.
