"One _will_ dream of it, nevertheless, and perhaps there is no man who has not said to himself at least once in his life: 'If I could but come to life again in a couple of centuries!' One would wish to return to earth to seek news of his family; another, of his dynasty. A philosopher is anxious to know if the ideas that he has planted will have borne fruit; a politician, if his party will have obtained the upper hand; a miser, if his heirs will not have dissipated the fortune he has made; a mere land-holder, if the trees in his garden will have grown tall. No one is indifferent to the future destinies of this world, which we gallop through in a few years, never to return to it again. Who has not envied the lot of Epimenides, who went to sleep in a cave, and, on reopening his eyes, perceived that the world had grown old? Who has not dreamed, on his own account, of the marvellous adventure of the sleeping Beauty in the wood? "Well, ladies, Professor Meiser, one of the least visionary men of the age, was persuaded that science could put a living being to sleep and wake him up again at the end of an infinite number of years--arrest all the functions of the system, suspend life itself, protect an individual against the action of time for a century or two, and afterwards resuscitate him." "He was a fool then!" cried Madame Renault. "I wouldn't swear it. But he had his own ideas touching the main-spring which moves a living organism. Do you remember, good mother mine, the impression you experienced as a little girl, when some one first showed you the inside of a watch in motion? You were satisfied that there was a restless little animal inside the case, who worked twenty-four hours a day at turning the hands. If the hands stopped going, you said: 'It is because the little animal is dead.' Yet possibly he was only asleep. "It has since been explained to you that a watch contains an assemblage of parts well fitted to each other and kept well oiled, which, being wound, can be considered to move spontaneously in a perfect correspondence. If a spring become broken, if a bit of the wheel work be injured, or if a grain of sand insinuate itself between two of the parts, the watch stops, and the children say rightly: 'The little animal is dead.' But suppose a sound watch, well made, right in every particular, and stopped because the machinery would not run from lack of oil; the little animal is not dead; nothing but a little oil is needed to wake him up.
