London, Macmillan & Co., 1933. First Edition. First Impression. A near fine copy with a little toning to the spine and a tear to the rear (scuffed externally, reinforced internally). A.E. was the pseudonym of George Russell. A decent copy, and featuring zero 12-foot blue humanoid eco-cats (more sky-beings philosophising). Bleiler has it simply as Futurity (it's entry one on page one of the book - not significant in the slightest, just fun to know...except if you're looking for somewhere to start!)
