London, Longmans, Green & Co., 1888. First edition, first impression. Hardback. A very good copy. Three volumes. Inscribed to 'Lady Jenner' by the author to half-title. Our protagonists encounter a Roman Utopia by means of submarine. Cloth in decent shape, a little bumped to the tips. A little light foxing to the endpapers. Volume one a little pulled at the endpaper, with a little splitting - likely replaced. [11036, Hyraxia Books].
