“The day ended without any change manifesting itself. The colonists did not leave the Nautilus. Night came, although unseen in this crypt.
Captain Nemo did not suffer pain, but sunk slowly. His noble face, pale by the approach of death, was perfectly calm. Now and then he spoke, incoherently, of events in his strange existence.—All saw that life was retreating. His feet and hands were already cold…
…The cocks were opened, the reservoirs filled, and the Nautilus, sinking slowly, disappeared beneath the sea.
But the colonists were able still to follow her coarse through the lower depths. Her strong light lit up the transparent waters, as the crypt became darkened. Then at length the vast effusion of electric effulgence was effaced, and the Nautilus, the tomb of Captain Nemo, rested upon the bottom of the sea.”
The Mysterious Island, Jules Verne, 1874
