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 this theory 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.

It would be impossible for me to describe these Beast People in detail; my eye has had no training in details, and unhappily I cannot sketch. Most striking, perhaps, in their general appearance was the disproportion between the legs of these creatures and the length of their bodies; and yet — so relative is our idea of grace — my eye became habituated to their forms, and at last I even fell in with their persuasion that my own long thighs were ungainly. Another point was the forward carriage of the head and the clumsy and inhuman curvature of the spine. Even the Ape-man lacked that inward sinuous curve of the back which makes the human figure so graceful. Most had their shoulders hunched clumsily, and their short forearms hung weakly at their sides. Few of them were conspicuously hairy, at least until the end of my time upon the island.

The next most obvious deformity was in their faces, almost all of which were prognathous, malformed about the ears, with large and protuberant noses, very furry or very bristly hair, and often strangely-coloured or strangely-placed eyes. None could laugh, though the Ape-man had a chattering titter. Beyond these general characters their heads had little in common; each preserved the quality of its particular species: the human mark distorted but did not hide the leopard, the ox, or the sow, or other animal or animals, from which the creature had been moulded. The voices, too, varied exceedingly. The hands were always malformed; and though some surprised me by their unexpected human appearance, almost all were deficient in the number of the digits, clumsy about the finger-nails, and lacking any tactile sensibility.

The two most formidable Animal Men were my Leopard-man and a creature made of hyena and swine. Larger than these were the three bull-creatures who pulled in the boat. Then came the silvery-hairy-man, who was also the Sayer of the Law, M’ling, and a satyr-like creature of ape and goat. There were three Swine-men and a Swine-woman, a mare-rhinoceros-creature, and several other females whose sources I did not ascertain. There were several wolf-creatures, a bear-bull, and a Saint-Bernard-man. I have already described the Ape-man, and there was a particularly hateful (and evil-smelling) old woman made of vixen and bear, whom I hated from the beginning. She was said to be a passionate votary of the Law. Smaller creatures were certain dappled youths and my little sloth-creature. But enough of this catalogue.

At first I had a shivering horror of the brutes, felt all too keenly that they were still brutes; but insensibly I became a little habituated to the idea of them, and moreover I was affected by Montgomery’s attitude towards them. He had been with them so long that he had come to regard them as almost normal human beings. His London days seemed a glorious, impossible past to him. Only once in a year or so did he go to Arica to deal with Moreau’s agent, a trader in animals there. He hardly met the finest type of mankind in that seafaring village of Spanish mongrels. The men aboard-ship, he told me, seemed at first just as strange to him as the Beast Men seemed to me, — unnaturally long in the leg, flat in the face, prominent in the forehead, suspicious, dangerous, and cold-hearted. In fact, he did not like men: his heart had warmed to me, he thought, because he had saved my life. I fancied even then that he had a sneaking kindness for some of these metamorphosed brutes, a vicious sympathy with some of their ways, but that he attempted to veil it from me at first.
