The _Nautilus_ floated in the midst of a phosphorescent bed which, in this obscurity, became quite dazzling. It was produced by myriads of luminous animalculae, whose brilliancy was increased as they glided over the metallic hull of the vessel. I was surprised by lightning in the midst of these luminous sheets, as though they had been rivulets of lead melted in an ardent furnace or metallic masses brought to a white heat, so that, by force of contrast, certain portions of light appeared to cast a shade in the midst of the general ignition, from which all shade seemed banished. No; this was not the calm irradiation of our ordinary lightning. There was unusual life and vigour: this was truly living light! In reality, it was an infinite agglomeration of coloured infusoria, of veritable globules of jelly, provided with a threadlike tentacle, and of which as many as twenty-five thousand have been counted in less than two cubic half-inches of water. During several hours the _Nautilus_ floated in these brilliant waves, and our admiration increased as we watched the marine monsters disporting themselves like salamanders. I saw there in the midst of this fire that burns not the swift and elegant porpoise (the indefatigable clown of the ocean), and some swordfish ten feet long, those prophetic heralds of the hurricane whose formidable sword would now and then strike the glass of the saloon. Then appeared the smaller fish, the balista, the leaping mackerel, wolf-thorn-tails, and a hundred others which striped the luminous atmosphere as they swam. This dazzling spectacle was enchanting! Perhaps some atmospheric condition increased the intensity of this phenomenon. Perhaps some storm agitated the surface of the waves. But at this depth of some yards, the _Nautilus_ was unmoved by its fury and reposed peacefully in still water. So we progressed, incessantly charmed by some new marvel. The days passed rapidly away, and I took no account of them. Ned, according to habit, tried to vary the diet on board. Like snails, we were fixed to our shells, and I declare it is easy to lead a snail’s life. Thus this life seemed easy and natural, and we thought no longer of the life we led on land; but something happened to recall us to the strangeness of our situation. On the 18th of January, the _Nautilus_ was in 105° long. and 15° S. lat. The weather was threatening, the sea rough and rolling. There was a strong east wind. The barometer, which had been going down for some days, foreboded a coming storm. I went up on to the platform just as the second lieutenant was taking the measure of the horary angles, and waited, according to habit till the daily phrase was said. But on this day it was exchanged for another phrase not less incomprehensible. Almost directly, I saw Captain Nemo appear with a glass, looking towards the horizon.
