"I don't want to be technical, and I know very little of what actually takes place myself. But I can try to give you some idea of it."
It is thousands, perhaps millions of years since Sir John explained to me. What little I understood at the time I may have forgotten, yet I try to reproduce what I can of his theory.
"In my study of the processes of birth," he began, "I discovered the rudiments of an action which takes place in the bodies of both men and women. There are certain properties in the foods we eat that remain in the body for the reproduction of life, two distinct Essences, so to speak, of which one is retained by the woman, another by the man. It is the union of these two properties that, of course, creates the child.
"Now, I made a slight mistake one day in experimenting with a guinea-pig, and I re-arranged certain organs which I need not describe so that I thought I had completely messed up the poor creature's abdomen. It lived, however, and I laid it aside. It was some years later that I happened to notice it again. It had not given birth to any young, but I was amazed to note that it had apparently grown no older: it seemed precisely in the same state of growth in which I had left it.
"From that I built up. I re-examined the guinea-pig, and observed it carefully. I need not detail my studies. But in the end I found that my 'mistake' had in reality been a momentous discovery. I found that I had only to close certain organs, to re-arrange certain ducts, and to open certain dormant organs, and, mirabile dictu, the whole process of reproduction was changed.
"You have heard, of course, that our bodies are continually changing, hour by hour, minute by minute, so that every few years we have been literally reborn. Some such principle as this seems to operate in reproduction, except that, instead of the old body being replaced by the new, and in its form, approximately, the new body is created apart from it. It is the creation of children that causes us to die, it would seem, because if this activity is, so to speak, dammed up or turned aside into new channels, the reproduction operates on the old body, renewing it continually. It is very obscure and very absurd, is it not? But the most absurd part of it is that it is true. Whatever the true explanation may be, the fact remains that the operation can be done, that it actually prolongs life indefinitely, and that I alone know the secret."
Sir John told me a very great deal more, but, after all, I think it amounted to little more than this. It would be impossible for me to express the great hold his discovery took upon my mind the moment he recounted it. From the very first, under the spell of his personality, I believed, and I knew he was speaking the truth. And it opened up before me new vistas. I began to see myself become suddenly eternal, never again to know the fear of death. I could see myself storing up, century after century, an amplitude of wisdom and experience that would make me truly a god.
"Sir John!" I cried, long before he was finished. "You must perform that operation on me!"
"But, Dennell, you are too hasty. You must not put yourself so rashly into my hands."
