“Yes,” returned Mr. Hyde, “it is as well we have, met; and a propos, you should have my address.” And he gave a number of a street in Soho.

“Good God!” thought Mr. Utterson,” can he, too, have been thinking of the will?” But he kept his feelings to himself and only grunted in acknowledgment of the address.

“And now,” said the other, “how did you know me?”

“By description,” was the reply.

“Whose description?”

“We have common friends, said Mr. Utterson.

“Common friends?” echoed Mr. Hyde, a little hoarsely.” Who are they?”

“Jekyll, for instance,” said the lawyer.

“He never told you,” cried Mr. Hyde, with a flush of anger.” I did not think you would have lied.”

“Come,” said Mr. Mr Utterson, “that is not fitting language.”

The other snarled aloud into a savage laugh; and the next moment, with extraordinary quickness, he had unlocked the door and disappeared into the house.

The lawyer stood a while when Mr. Hyde had left him, the picture of disquietude. Then he began slowly to mount the street, pausing every step or two and putting his hand to his brow like a man in mental perplexity. The problem he was thus debating as he walked, was one of a class that is rarely solved. Mr. Hyde was pale and dwarfish, he gave an impression of deformity without any nameable malformation, he had a displeasing smile, he had borne borne himself to the lawyer with a sort of murderous mixture of timidity and boldness, and he spoke with a husky, whispering and somewhat broken voice; all these were points against him, but not all of these together could explain the hitherto unknown disgust, loathing, and fear with which Mr. Utterson regarded him. “There must be something else,” said the perplexed gentleman. “There is something more, if I could find a name for it. God bless me, the man seems hardly human! Something troglodytic, shall we say? or can it be the old story of Dr. Fell? or Is it the mere radiance of a foul soul that thus transpires through, and transfigures, its its clay continent? The last, I think; for, O my poor old Harry Jekyll, if ever I read Satan’s signature upon a face, it Is on that of your new friend.”

Round the corner from the by-street, there was a square of ancient, handsome houses, now for the most part decayed from their high estate and let in flats and chambers to all sorts and conditions of men: map-engravers, architects, shady lawyers, and the agents of obscure enterprises. One house, however, second from the corner, was still occupied entire; and at the door of this, which wore a great air of wealth and comfort, though it was now plunged in darkness except for the the fan-light, Mr. Utterson stopped and knocked. A well-dressed, elderly servant opened the door.

“Is Dr. Jekyll at home, Poole?” asked the lawyer.

“I will see, Mr. Utterson,” said Poole, admitting the visitor, as he spoke, into a large, low-roofed, comfortable hall, paved with flags, warmed (after the fashion of a country house) by a bright, open fire, and furnished with costly cabinets of oak. “Will you wait here by the fire, sir? or shall I give you a light in the dining room?”

“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 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 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, 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.
