New York: E.P. Dutton, 1919. First edition. 8vo, xvi, , 395 pp. Includes bibliography and index. Bound in gilt-stamped blue cloth. No dust jacket.
Rare and unusual work which, according to O'Regan, was the first to apply the concept of hyperspace to the exploration of consciousness. "The direct application of the hyperspace idea to the study of consciousness seems to have been started over 50 years ago by Robert Browne in his volume "The Mystery of Space' .... he suggested that mathematics is a true 'biometer of intellectual evolution' and that the hyperspace movement represents 'an actual seizure of a new domain of awareness of the mind.''"
Gilt dulled at spine, with some minor rubbing to extremities. Previous owner's small rubberstamp (that of D. F. Comstock, perhaps the early 20th century physicist?), old price written tastefully in red pencil, and an old bookseller's ticket form The Old Corner Bookshop in Boston to ffe. Small abrasion and a couple faint smudges to prelims, overopened just slightly at the title page, else a very good example.
Scarce. Item #27647
