London, Ward, Lock & Co., 1899. First edition, first impression. Hardback. A good copy. An uncommon sf thriller mixing together a number of tropes, but the main being messing about with atoms to screw up the universe. Library plate to the front pastedown - but that's it for markings. Slight lean and some gentle wear to the board edges, some foxing and a the front hinge is a little separated, first plate almost loose along with the the tissueguard. Title page foxed. Some offsetting. [10234, Hyraxia Books].
