A Journey in Other Worlds: A Romance of the Future! A Science Fiction, Adventure Classic By J. J. Astor! AAA+++

"The author speculates cleverly and daringly on the scientific advance of the earth, and he revels in the physical luxuriance of Jupiter; but he also lets his imagination travel through spiritual realms, and evidently delights in mystic speculation quite as much as in scientific investigation. If he is a follower of Jules Verne, he has not forgotten also to study the philosophers."
