"And what of the girl whose body you gave to the Jeddara?" I asked, irrelevantly, for my mind could not efface the memory of that sweet body that must, indeed, have possessed an equally sweet and fine brain.

"Merely a subject! Merely a subject!" he replied with a wave of his hand.

"What will become of her?" I insisted.

"What difference does it make?" he demanded. "I bought her with a batch of prisoners of war. I do not even recall from what country my agent obtained them, or from whence they originated. Such matters are of no import."

"She was alive when you bought her?" I demanded.

"Yes. Why?"

"You-er-ah-killed her, then?"

"Killed her! No; I preserved her. That was some ten years ago. Why should I permit her to grow old and wrinkled? She would no longer have the same value then, would she? No, I preserved her. When Xaxa bought her she was just as fresh and young as the day she arrived. I kept her a long time. Many women looked at her and wanted her face and figure, but it took a Jeddara to afford her. She brought the highest price that I have ever been paid.

"Yes, I kept her a long time, but I knew that some day she would bring my price."

"She was indeed beautiful and so sentiment has its uses-were it not for sentiment there would be no fools to support this work that I am doing, thus permitting me to carry on investigations of far greater merit. You would be surprised, I know, were I to tell you that I feel that I am almost upon the point of being able to produce rational human beings through the action upon certain chemical combinations of a group of rays probably entirely undiscovered by your scientists, if I am to judge by the paucity of your knowledge concerning such things."

"I would not be surprised," I assured him. "I would not be surprised by anything that you might accomplish."

I lay awake a long time that night thinking of 4296-E-2631-H, the beautiful girl whose perfect body had been stolen to furnish a gorgeous setting for the cruel brain of a tyrant. 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. I could only see a stricken girl grieving for her lost beauties. With a muffled oath I turned away. I could not do it! And then, as though an outside force had seized upon me, my finger moved unerringly to the button and pressed it. I cannot explain it, unless upon the theory of dual mentality, which may explain many things. Perhaps my subjective mind directed the act. I do not know. Only I know that I did it, the motor started, the level of the blood in the container commenced gradually to lower.
