The Rat
by S. Fowler Wright
I
Dr. Merson looked at the dying rat, and decided that, should he delay his experiment longer, it would be dead before morning.
He had nursed it now for nearly six months, and it had been very old and blind and feeble when he had bought it.
He had told Briggs that he would give him £5 for the oldest rat in Belsham, and the rat-catcher had earned his money.
It had surprised him, when he had first approached the subject, to realize how difficult it would be to find an animal that was really old and feeble. He had to observe that nature does not encourage the prolongation of pain and weariness: when health goes, life very quickly follows.
But he knew that, in the course of their age-long warfare with the human race, the rats had arrived at some social organization, and had adopted some of our practices, and in particular, that when a disease of blindness (to which they are very liable) attacks them, they may be nursed and fed by members of their family, so that life is prolonged to an age which would otherwise be impossible.
So he had asked for an aged rat, and had watched its vitality recede, till now it was too weak to crawl toward the tempting food that was offered... It was so dull with age that it did not flinch when the needle pricked it.

The next morning it was not dead. It lay sleeping; old, and blind, and decrepit. It was not pleasant to look at, but it may have been less feeble than the night before — and the food had been eaten.
Dr. Merson, observing this, became aware that his heart was beating fast, with a sudden excitement, of which he had not supposed himself to be capable.
When he looked at it again at midday, and observed that it was feebly attending to a neglected toilet, he did a thing which was less wise than his usual custom, calling his wife to observe it.
Mrs. Merson disliked his experiments; and his own habit of professional reticence disinclined him from speech which had no immediate purpose. But this was a discovery of such momentous consequence that he was impelled to share it.
“You mean that no one need ever die?” she asked incredulously. She was not greatly impressed, even if she took it with any seriousness. She was a healthy young woman, utterly without imagination, and the cook had given notice an hour ago.
“Yes, it might mean that — or nearly — unless by accident... You see,” he continued, to an auditor who scarcely heard him, “it isn’t really new. We’ve known for a long time that youth would continue if the cells of which the body is built could have the right stimuli, but it’s been difficult to find what they are. Some of the lower forms of life never die, as it is. The old ones break apart, and each part acquires a new impulse of growth from the shock of that division. But in the higher animals there is a change in the substance or activities of the cells as the years pass, the nature of which has been difficult to ascertain, though its results have been evident...”
He stopped, as he became aware that Mrs. Merson had ceased to listen. She regarded the sleeping rat with disfavor.
“I shouldn’t think anything wants to live when it’s that old,” she said, with decision. She had the impatience of healthy youth for all signs of decrepitude. They seemed stupid.
She heard the voice of the butcher at the back door, and her mind reverted to matters of greater urgency. She went back to the kitchen.

The rat improved very slowly. Its appetite increased. It moved more briskly. It gained weight. It gave more attention to its toilet. It became wilder, and more alert to the sounds around it. Finally, its sight returned.
The process was not rapid, but continuous. At the end of three months from when it had received the injection (which had not been repeated), it showed the bodily activity and physique of a young rat.
Dr. Merson did not mention it again to his wife, nor did he seek another confidant. He became thoughtful, and, at times, appeared to be suffering from acute depression. His patients complained, and his practice suffered.
The fact is that he was beginning to fear the consequences of his discovery.
At first, it had seemed simple — and stupendous. He was about to benefit his race as no man had done before him. Had he not found a way by which death itself was defeated? He saw that it would change the whole face of the earth. Old age would become an obscene tradition. Disease would be powerless to overcome the new vitality which he had discovered. Men would no longer die as their minds approached the threshold of wisdom.
He thought of his own patients. There was Mrs. Corner, who would be dead of tuberculosis within a year, unless he should use his new power for her rescue — Minnie Corner, with three young children, fighting her hopeless battle, always “a little better to-day” when he called to watch the slow, relentless progress of a disease that he could not conquer. He would he very glad to give her health. Having it in his power, it was a clear and simple duty, as her doctor, to do it. But (so far as he could suppose) he would do more than that. He would give her an approximation to immortality. Not absolute immortality. Her body would still be liable to be damaged or destroyed by violence. Certainly, it would have no power to survive the planet on which it lived. It would be liable to drowning, or suffocation. But it would no longer be in subjection to the treachery of time. Fed, and guarded from violence, it would not age nor decay. There was something odd in imagining Minnie Corner immortal. But there was nothing repellent. He supposed it would mean treating her children in the same way. They would be annoyed if they observed themselves growing old and feeble, while their mother remained young. It would confuse the relationship. Neither would she thank him for such a tableau. He knew Mrs. Corner well enough to realize that there would be no rest for him till he had conferred the same boon upon her household that he should give to her. Well, why not?
About two of the children there would be no difficulty. But he disliked Peter. He disliked Peter intensely. He could not endure the thought of an immortal Peter. It wasn’t the clubfoot, though it did seem a pity that it should become an abiding feature of a world grown static: it was certain qualities of meanness and cruelty which the boy had shown from infancy, which his mother had lamented, but which she had been powerless to influence.
According to the law of nature which now prevailed, Peter would grow old, and in due course he would die, and his unpleasant characteristics would perish with him. He might have children, but these children would be different from himself, whether better or worse, and, in due course, they would have still different children, the race repeating itself with an unending variety.
Somehow, this seemed a better prospect than that of an enduring Peter.
Yet he could not imagine an arrangement being smoothly made by which Peter would be consigned to an exceptional mortality. However carefully his moral and physical inferiorities, and the importance of his early elimination, might be explained to him, Dr. Merson felt sure that he would resent it furiously. He imagined a violent assault upon his own person by an adult and desperate Peter to whom he was refusing the boon of immortality. Even a murderous assault...
His mind was diverted to observe that murder would become a more serious crime than it now is — the risk of being murdered a more dreadful possibility. Indeed, all physical risks would be taken at an almost infinitely greater price, and — presumably — with a corresponding reluctance.
