" White spiders, demon-headed and large as monkeys, had woven their webs in the hollow arches of the bones; and they swarmed out interminably as Nushain approached; and the skeleton seemed to stir and quiver as they seethed over it abhorrently and dropped to the ground before the astrologer. Behind them others poured in a countless army, crowding and mantling every ossicle. "
