This new bilingual editon of Vingt mille lieues sous les mers / Twenty thousand leagues under the sea is translated from French into English by Henry Frith (1876).
With more than 100 illustrations byAlphonse de Neuille and Édouard Riou for the original French version (1870).

This novel is a classic science fiction adventure novel by French writer Jules Verne, originally serialized from March 1869 through June 1870 in Pierre-Jules Hetzel's fortnightly periodical, the Magasin d'éducation et de récréation.
A deluxe octavo edition, published by Hetzel in November 1871, included 111 illustrations by Alphonse de Neuville and Édouard Riou. The book was widely acclaimed on its release and remains so; it is regarded as one of the premiere adventure novels and one of Verne's greatest works, along with Around the World in Eighty Days and Journey to the Center of the Earth. Its depiction of Captain Nemo's underwater ship, the Nautilus, is regarded as ahead of its time.

Plot:
During the year 1866, ships of various nationalities sight a mysterious sea monster, which, it is later suggested, might be a gigantic narwhal. The U.S. government assembles an expedition in New York City to find and destroy the monster. Professor Pierre Aronnax, a French marine biologist and the story's narrator, is in town at the time and receives a last-minute invitation to join the expedition; he accepts. Canadian whaler and master harpooner Ned Land and Aronnax's faithful manservant Conseil are also among the participants.
The expedition leaves Brooklyn aboard the United States Navy frigate Abraham Lincoln, then travels south around Cape Horn into the Pacific Ocean. After a five-month search ending off Japan, the frigate locates and attacks the monster, which damages the ship's rudder. Aronnax and Land are hurled into the sea, and Conseil jumps into the water after them. They survive by climbing onto the "monster," which, they are startled to find, is a futuristic submarine. They wait on the deck of the vessel until morning, when they are captured, hauled inside, and introduced to the submarine's mysterious constructor and commander, Captain Nemo.
They visit many ocean regions, some factual and others fictitious. The travelers view coral formations, sunken vessels from the battle of Vigo Bay, the Antarctic ice barrier, the Transatlantic telegraph cable, and the legendary underwater realm of Atlantis. They even travel to the South Pole and are trapped in an upheaval of an iceberg on the way back, caught in a narrow gallery of ice from which they are forced to dig themselves out. The passengers also don diving suits, hunt sharks and other marine fauna with air guns in the underwater forests of Crespo Island, and also attend an undersea funeral for a crew member who died during a mysterious collision experienced by the Nautilus. When the submarine returns to the Atlantic Ocean, a school of "poulpes" attacks the vessel and kills a crewman. (In French "poulpe" is a generic term for a cephalopod, such as a cuttlefish, octopus, etc. - the noun "devilfish" is a close English equivalent. Verne's text specifies that the monster in this case is "un calamar de dimensions colossales", "a squid of colossal dimensions", i.e, a giant squid.).

According to Verne's editor Pierre-Jules Hetzel, the goal of the Voyages was "to outline all the geographical, geological, physical, historical and astronomical knowledge amassed by modern science and to recount, in an entertaining and picturesque format ... the history of the universe."
