A most remarkable book.... Surpasses, in my judgment, any thing that has been written by the elder Dumas or Jules Verne, while in moral purpose it is equal to Hugo at his best.... It appeals to the thoughtful scientist no less than to the lover of fascinating romance. [Sidenote: Mr. Herbert Bates, in the Commercial Gazette, Cincinnati.] In summing, I would say that I have found the book distinctly stimulating. It is odd, but with the oddity of force. It has passages of uncanny imagination, but they excellently evade the enormous and extravagant. It is a book that by its title and by such features as strike one at a hurried glance might easily repel. Yet it is a book that, studied carefully, calls for re-reading and deep meditation. Its theories are capable of scientific demonstration, its imaginings, while they may not be fact, are always consistent with it. The reader who lets the outside repel him errs sadly. Let him read it, and he will be as changed in his position toward it, as ready to convert others, as is the reviewer, who picked it up with foreboding and laid it down with the sense of having read great thoughts. [Sidenote: Dr. W. H. Venable.] "The End of Earth" is not like any other book. The charm of adventure, the excitement of romance, the stimulating heat of controversy, the keen pursuit of scientific truth, the glow of moral enthusiasm, are all found in its pages. The book may be described as a sort of philosophical fiction, containing much exact scientific truth, many bold theories, and much ingenious speculation on the nature and destiny of man.... The occult and esoteric character of the discussions adds a strange fascination to them. We can hardly classify, by ordinary rules, a work so unusual in form and purpose, so discursive in subject-matter, so unconventional in its appeals to reason, religion and morality.... The direct teaching of the book, in so far as it aims to influence conduct, is always lofty and pure. [Sidenote: Letter from Sir Henry Irving, to the Author.] "_My Dear Sir:_ Let me thank you most heartily for sending me the special copy of your wonderful book 'Etidorhpa,' which I shall ever value. I may say that when by chance I found it in Cincinnati I read it with the greatest interest and pleasure, and was so struck by it that I have sent copies to several friends of mine here and at home. I hope I may have the pleasure of meeting you some day either here or in London. I remain, sincerely yours, HENRY IRVING. "20th March, 1896." [Sidenote: Etidorhpa as a work of art. Prof. S. W. Williams.] If a fine statute or a stately cathedral is a poem in marble, a masterpiece of the printer's art may be called a poem in typography. Such is "Etidorhpa." In its paper, composition, presswork, illustrations, and binding--it is the perfection of beauty. While there is nothing gaudy in its outward appearance, there is throughout a display of good taste.
