London, Henry J. Drane, 1897. First edition, first impression. Hardback. A very good copy. Inscribed by the author on the half-title. Eight plates. An important "Lost race adventure novel in which the inhabitants are kept in line by means of 'miracles' caused by, among other things, poisons which can apparently kill but whose effects can be reversed, and a light sceptre which controls volition." [Locke, Spectrum II:49]. Some tanning to the spine, a slight reading lean and some light stains to the cloth. Illustrations by E.A. Holloway [11736, Hyraxia Books].
