- On cover: "The following pages have been reprinted from articles (which have recently appeared in various journals), in answer to the many inquiries made in reference to the present position of John Worrell Keely, in his experimental researches, it having become widely known that he has not yet gained sufficient mastery of this force to construct a patentable engine, and that he has now turned his attention to aerial navigation in which one of the forces he has discovered can be used without an engine.
