“Monsters manufactured!” said I. “Then you mean to tell me — ”

“Yes. These creatures you have seen are animals carven and wrought into new shapes. To that, to the study of the plasticity of living forms, my life has been devoted. I have studied for years, gaining in knowledge as I go. I see you look horrified, and yet I am telling you nothing new. It all lay in the surface of practical anatomy years ago, but no one had the temerity to touch it. It is not simply the outward form of an animal which I can change. The physiology, the chemical rhythm of the creature, may also be made to undergo an enduring modification, — of which vaccination and other methods of inoculation with living or dead matter are examples that will, no doubt, be familiar to you. A similar operation is the transfusion of blood, — with which subject, indeed, I began. These are all familiar cases. Less so, and probably far more extensive, were the operations of those mediaeval practitioners who made dwarfs and beggar-cripples, show-monsters, — some vestiges of whose art still remain in the preliminary manipulation of the young mountebank or contortionist. Victor Hugo gives an account of them in ‘L’Homme qui Rit.’ — But perhaps my meaning grows plain now. You begin to see that it is a possible thing to transplant tissue from one part of an animal to another, another or from one animal to another; to alter its chemical reactions and methods of growth; to modify the articulations of its limbs; and, indeed, to change it in its most intimate structure.

“And yet this extraordinary branch of knowledge has never been sought as an end, and systematically, by modern investigators until I took it up! Some of such things have been hit upon in the last resort of surgery; most of the kindred evidence that will recur to your mind has been demonstrated as it were by accident, — by tyrants, by criminals, by the breeders of horses and dogs, by all kinds of untrained clumsy-handed men working for their own immediate ends. I was the first man to take up this question armed with antiseptic surgery, and with a really scientific knowledge of the laws of growth. Yet one would imagine it must have been practised in secret before. Such creatures as the Siamese Twins — And in the vaults of the Inquisition. No doubt their chief aim was artistic torture, but some at least of the inquisitors must have had a touch of scientific curiosity.”

“But,” said I, “these things — these animals talk!”

He said that was so, and proceeded to point out that the possibility of vivisection does not stop at a mere physical metamorphosis. A pig may be educated. The mental structure is even less determinate than the bodily. In our growing science of hypnotism we find the promise of a possibility of superseding old inherent instincts by new suggestions, grafting upon or replacing the inherited fixed ideas. Very much indeed of what we call moral education, he said, is such an artificial modification and perversion of instinct; pugnacity is trained into courageous self-sacrifice, and suppressed sexuality into religious emotion. And the great difference between man and monkey is in the larynx, he continued, — in the incapacity to frame delicately different sound-symbols by which thought could be sustained. In this I failed to agree with him, but with a certain incivility he declined to notice my objection. He repeated that the thing was so, and continued his account of his work.

It was a wild, cold, seasonable night of March, with a pale moon, lying on her back as though the wind had tilted her, and a flying wrack of the most diaphanous and lawny texture. The wind made talking difficult, and flecked the blood into the face. It seemed to have swept the streets unusually bare of passengers, besides; for Mr. Utterson thought he had never seen that part of London so deserted. He could have wished it otherwise; never in his life had he been conscious of so sharp a wish to see and touch his fellow-creatures; for struggle as he might, there was borne in upon his mind a crushing anticipation of calamity. The square, when they got there, was all full of wind and dust, and the thin trees in the garden were lashing themselves along the railing. Poole, who had kept all the way a pace or two ahead, now pulled up in the middle of the pavement, and in spite of the biting weather, took off his hat and mopped his brow with a red pocket-handkerchief. But for all the hurry of his cowing, these were not the dews of exertion that he wiped away, but the moisture of some strangling anguish; for his face was white and his voice, when he spoke, harsh and broken.

“Well, sir,” he said, “here we are, and God grant there be nothing wrong.”

“Amen, Poole,” said the lawyer.

Thereupon the servant knocked in a very guarded manner; the door was opened on the chain; and a voice asked from within, “Is that you, Poole?”

“It’s all right,” said Poole. “Open the door.” The hall, when they entered it, was brightly lighted up; the fire was built high; and about the hearth the whole of the servants, men and women, stood huddled together like a flock of sheep. At the sight of Mr. Utterson, the housemaid broke into hysterical whimpering; and the cook, crying out, “Bless God! it’s Mr. Utterson,” ran forward as if to take him in her arms.

“What, what? Are you all here?” said the lawyer peevishly. “Very irregular, very unseemly; your master would be far from pleased.”

“They’re all afraid,” said Poole.

Blank silence followed, no one protesting; only the maid lifted up her voice and now wept loudly.

“Hold your tongue!” Poole said to her, with a ferocity of accent that testified to his own jangled nerves; and indeed, when the girl had so suddenly raised the note of her lamentation, they had all started and turned toward the inner door with faces of dreadful expectation. “And now,” continued the butler, addressing the knife-boy, “reach me a candle, and we’ll get this through hands at once.” And then he begged Mr. Utterson to follow him, and led the way to the back-garden.

“Now, sir,” said he, “you come as gently as you can. I want you to hear, and I don’t want you to be heard. And see here, sir, if by any chance he was to ask you in, don’t go.”

Mr. Utterson’s nerves, at this unlooked-for termination, gave a jerk that nearly threw him from his balance; but he re-collected his courage and followed the butler into the laboratory building and through the surgical theatre, with its lumber of crates and bottles, to the foot of the stair. Here Poole motioned him to stand on one side and listen; while he himself, setting down the candle and making a great and obvious call on his resolution, mounted the steps and knocked with a somewhat uncertain hand on the red baize of the cabinet door.
