of the book must have been as nothing compared with the very arduous thought and study connected with the mental generation of the views held by Heliobas and his fellow-believers.

It ought to be remembered, too, that, at the time the "Romance" was published, the wonders of the X-rays had not been demonstrated, nor had wireless telegraphy become a fait accompli. Yet these were distinctly foretold in Marie Corelli's first book, as also the possible wonders yet to be proved in certain new scientific theories of Sound and Color. It may instruct many to know that the theory of God's "Central World" with which all the universe moves, is a part of the authoress's own implicit belief in a future state of being.
