This kind of takes up where Paul Alkon leaves off.
I have Istvan Aggott, a Canadian of Hungarian extraction, taking notes for me on JOVO SZAZAD REGENYE (A NOVEL OF THE COMING CENTURY), which was published in two volumes in 1872 and 1874. There was a German translation in 1879 but, to the best of my knowledge, it has never appeared in any other language.
