London, Sidgwick & Jackson, 1911. First Edition. First Impression. Hardback. A very good copy. The author's second book, and an important entry in the area of super-humans in speculative fiction. A noted influence on Olaf Stapledon, and influenced itself by Wells. Some toning to the spine, endpapers toned. Light foxing to edges. A decent copy. [Bleiler, p21]. [6635, Hyraxia Books].
