London, Simpkin, Marshall, Hamilton, Kent & Co., 1919. First Edition. First Impression. Lost Race. In Blieler under lost race / immortality [p145]. "Set in a lost world whose inhabitants gain longevity through bathing in a radioactive pool, which also disfigures them" [Clute, p837]. The present copy has a hand-written note in pencil stating that the book's to deal with radiation sickness, though how accurate that is we can't be certain; there were real-world cases of radiation poisoning prior to 1919, though it's unclear how much was known about it. "A story of a mysterious tribe living in an island in remote Eastern seas. This is visited by the hero in search of a mysterious drug. In the end:the islandisengulfed by an earthquake, and the exceed- ingly attractive woman Sultan drowned." [Spectator, 30/05/1919]. The book is in its jacket, which is uncommon. The jacket is split in two along the spine crease, though knits together nicely. Spine tips chipped with the 'E' of East lost. Price sticker to jacket front. Book itself in decent shape.
