All this fossil world rises to life again in my vivid imagination. I return to the scriptural periods or ages of the world, conventionally called 'days,' long before the appearance of man, when the unfinished world was as yet unfitted for his support. Then my dream backed even farther still into the ages before the creation of living beings. The mammals disappear, then the birds vanish, then the reptiles of the secondary period, and finally the fish, the crustaceans, molluscs, and articulated beings. Then the zoophytes of the transition period also return to nothing. I am the only living thing in the world: all life is concentrated in my beating heart alone. There are no more seasons; climates are no more; the heat of the globe continually increases and neutralises that of the sun. Vegetation becomes accelerated. I glide like a shade amongst arborescent ferns, treading with unsteady feet the coloured marls and the particoloured clays; I lean for support against the trunks of immense conifers; I lie in the shade of sphenophylla (wedge-leaved), asterophylla (star-leaved), and lycopods, a hundred feet high. Ages seem no more than days! I am passed, against my will, in retrograde order, through the long series of terrestrial changes. Plants disappear; granite rocks soften; intense heat converts solid bodies into thick fluids; the waters again cover the face of the earth; they boil, they rise in whirling eddies of steam; white and ghastly mists wrap round the shifting forms of the earth, which by imperceptible degrees dissolves into a gaseous mass, glowing fiery red and white, as large and as shining as the sun. And I myself am floating with wild caprice in the midst of this nebulous mass of fourteen hundred thousand times the volume of the earth into which it will one day be condensed, and carried forward amongst the planetary bodies. My body is no longer firm and terrestrial; it is resolved into its constituent atoms, subtilised, volatilised. Sublimed into imponderable vapour, I mingle and am lost in the endless floods of those vast globular volumes of vaporous mists, which roll upon their flaming orbits through infinite space. But is it not a dream? Whither is it carrying me? My feverish hand has vainly attempted to describe upon paper its strange and wonderful details. I have forgotten everything that surrounds me. The Professor, the guide, the raft--are all gone out of my ken. An illusion has laid hold upon me. "What is the matter?" my uncle breaks in. My staring eyes are fixed vacantly upon him. "Take care, Axel, or you will fall overboard." At that moment I felt the sinewy hand of Hans seizing me vigorously. But for him, carried away by my dream, I should have thrown myself into the sea. "Is he mad?" cried the Professor. "What is it all about?" at last I cried, returning to myself. "Do you feel ill?" my uncle asked. "No; but I have had a strange hallucination; it is over now. Is all going on right?"
