Worlds in a glacial state. Life arrested.
The awakening out of glacial repose.
There are worlds now in this state. They are eccentric worlds, the life of whose inhabitants has been insensibly arrested by the rapid flight of their planet away from the Sun, and they have been transformed into millions of statues. Most of them are lying down asleep, seeing that this profound change of temperature takes many days in its accomplishment. There they are by millions, pell-mell, dead, or, to be more accurate, sunk in a complete lethargy. The cold preserves them. Three or four thousand years later, when the planet returns from its dark and frozen aphelion to its brilliant perihelion, towards the sun—whose fertilising heat caressing its surface with welcoming rays will rapidly increase—and when it has reached the degree which betokens the normal temperature of these beings, they will be resuscitated at the age at which they were when overtaken by sleep; they will take up their affairs from the moment of their interruption (long interruption indeed!) without any consciousness that they had slept a dreamless sleep for so many ages. One may see some continuing a game, or finishing a phrase whose first words have been uttered four thousand years ago. All this is perfectly simple, for we have seen that time does not in reality exist. This, on a large scale, is exactly what passes on a small one on the Earth when you revive infusoria, which take a fresh lease of life under the rain, after several years of apparent death.
World of Andromeda.
But to return to our world of Andromeda; the rose-coloured and quasi-liquid atmosphere, surrounding it entirely as an ocean without islands, is the abode of living beings, who are perpetually floating in the depths of that ocean which none have ever sounded: from their birth to their death they have not one moment's repose. Incessant activity is the condition of their existence. Should they become stationary they would perish. In order to breathe, that is to say, to enable this fluid element to penetrate to their bosom, they are constrained to keep their tentacles in unceasing motion, and their lungs (I use this word the better to be understood) constantly open.
Process of nourishment.
The external form of this human race resembles that of the sirens of antiquity, but is less elegant, and their organism approaches that of the seal. Do you see the essential difference between their constitution and that of terrestrial man? It is that on the Earth we breathe without being conscious of the act, and obtain oxygen without exertion, not being compelled with difficulty to convert venous into arterial blood by the absorption of oxygen. Upon this other world, on the contrary, this nourishment is only obtained with labour and at the price of incessant effort.
Quærens. Then this world is inferior to ours in the scale of progress?
Lumen. Without any doubt, seeing that I inhabited it before coming upon the Earth. But do not think that the Earth is much superior by reason of our being able to breathe whilst we are asleep. Doubtless, it is a great advantage to be furnished with a pneumatic mechanism, which opens involuntarily every time that our organism needs the least breath of air, and which acts automatically and unceasingly night and day. But man does not live on air alone; his earthly organism requires to be nourished with something more solid, and this solid something does not come to him involuntarily as does air.
Labour of life on the Earth.
