Note: Peter Costello's Introduction to The Eternal Adam and Other Stories states "'In the Twenty-Ninth Century', though it may have been suggested by conversations with Jules Verne, was written in English by his son Michel though published under Verne's own name (as contemporary correspondence reveals) ... However the French version, from which the translation here has been made, was revised by Verne himself." Translated by an unknown hand. This title contains publications where the translation (as well as the translator) is unknown. Please see this wiki page for more information on known translations.
