It seemed such a horrid crime that I could not rid my mind of it and I think that contemplation of it sowed the first seed of my hatred and loathing for Ras Thavas. I could not conjure a creature so utterly devoid of bowels of compassion as to even consider for a moment the frightful ravishing of that sweet and lovely body for even the holiest of purposes, much less one that could have been induced to do so for filthy pelf.

So much did I think upon the girl that night that her image was the first to impinge upon my returning consciousness at dawn, and after I had eaten, Ras Thavas not having appeared, I went directly to the storage room where the poor thing was. Here she lay, identified only by a small panel, bearing a number: 4296-E-2631-H. The body of an old woman with a disfigured face lay before me in the rigid immobility of death; yet that was not the figure that I saw, but instead, a vision of radiant loveliness whose imprisoned soul lay dormant beneath those greying locks.

The creature here with the face and form of Xaxa was not Xaxa at all, for all that made the other what she was had been transferred to this cold corpse. How frightful would be the awakening, should awakening ever come! I shuddered to think of the horror that must overwhelm the girl when first she realized the horrid crime that had been perpetrated upon her. Who was she? What story lay locked in that dead and silent brain? What loves must have been hers whose beauty was so great and upon whose fair face had lain the indelible imprint of graciousness! Would Ras Thavas ever arouse her from this happy semblance of death? — far happier than any quickening ever could be for her. I shrank from the thought of her awakening and yet I longed to hear her speak, to know that that brain lived again, to learn her name, to listen to the story of this gentle life that had been so rudely snatched from its proper environment and so cruelly handled by the hand of Fate. And suppose she were awakened! Suppose she were awakened and that I-A hand was laid upon my shoulder and I turned to look into the face of Ras Thavas.

You seem interested in this subject," he said.

"I was wondering," I replied, "what the reaction this girl's brain would be were she to awaken to the discovery that she had become an old, disfigured woman."

He stroked his chin and eyed me narrowly. "An interesting experiment," he mused.

"I am gratified to discover that you are taking a scientific interest in the labours that I am carrying on. The psychological phases of my work I have, I must confess, rather neglected during the past hundred years or so, though I formerly gave them a great deal of attention. It would be interesting to observe and study several of these cases. This one, especially, might prove of value to you as an initial study, it being simple and regular. Later we will let you examine into a case where a man's brain has been transferred to a woman's skull, and a woman's brain to a man's. There are also the interesting cases where a portion of diseased or injured brain has been replaced by a portion of the brain from another subject, and, for experimental purposes alone, those human brains that have been transplanted to the craniums of beasts, and vice versa, offer tremendous opportunities for observation. I have in mind one case in which I transferred half the brain of an ape to the skull of a man, after having removed half of his brain, which I grafted upon the remaining part of the brain in the ape's skull. That was a matter of several years ago and I have often thought that I should like to recall these two subjects and note the results. I shall have to have a look at them-as I recall it they are in vault L-42-X, beneath building 4-J-21. We shall have to have a look at them someday soon-it has been years since I have been below. There must be some very interesting specimens there that have escaped my mind. But come! let us recall 4296-E-2631-H.

"No!" I exclaimed, laying a hand upon his arm. "It would be horrible."

He turned a surprised look upon me and then a nasty, sneering smile curled his lips. "Maudlin, sentimental fool!" he cried. "Who dare say no to me?"

I laid a hand upon the hilt of my long-sword and looked him steadily in the eye.

"Ras Thavas," I said, "you are master in your own house; but while I am your guest treat me with courtesy."

He returned my look for a moment but his eyes wavered. "I was hasty," he said.

"Let it pass." That, I let answer for an apology-really it was more than I had expected-but the event was not unfortunate. I think he treated me with far greater respect thereafter; but now he turned immediately to the slab bearing the mortal remains of 4296-E-2631-H.

"Prepare the subject for revivification," he said, "and make what study you can of all its reactions." With that he left the room.

I was now fairly adept at this work which I set about with some misgivings but with the assurance that I was doing right in obeying Ras Thavas while I remained a member of his entourage. The blood that had once flowed through the veins of the beautiful body that Ras Thavas had sold to Xaxa reposed in an hermetically sealed vessel upon the shelf above the corpse. As I had before done in other cases beneath the watchful eyes of the old surgeon I now did for the first time alone. The blood heated, the incisions made, the tubes attached and the few drops of life-giving solution added to the blood, I was now ready to restore life to that delicate brain that had lain dead for ten years. As my finger rested upon the little button that actuated the motor that was to send the revivifying liquid into those dormant veins, I experienced such a sensation as I imagined no mortal man has ever felt.

I had become master of life and death, and yet at this moment that I stood there upon the point of resurrecting the dead I felt more like a murderer than a saviour. I tried to view the procedure dispassionately through the cold eye of science, but I failed miserably.
