Page "Captain Nemo" Paragraph 36

The Nautilus goes down in the Maelstrom on June 2, 1868, according to 20, 000 Leagues Under The Sea, but may have survived.

( The Mysterious Island gives this date as June 22, 1867.

) Captain Nemo dies on the Nautilus under Lincoln Island in The Mysterious Island on October 15, 1868.

So while the date of his death in the latter novel does not precede his adventures in the former novel, some chronological inconsistencies still exist: Cyrus and Gideon knew of Captain Nemo years before Aronnax published his story ; Nemo being trapped under Lincoln Island all during the time in 20, 000 Leagues Under The Sea.
