In every respect the volume bearing the title Etidorhpa, or the End of the Earth, is a most remarkable book. Typographically, it is both unique and artistic—as near perfection in conception and execution as can be conceived.... The author is John Uri Lloyd, of Cincinnati, a scientific writer whose pharmaceutical treatises are widely known and highly valued. That a man whose mind and time have been engrossed with the affairs of a specialist and man of affairs could have found time to enter the field of speculation, and there display not only the most extensive knowledge of the exact natural sciences, and refute what is held to be scientific truth with bold theories and ingenious speculations on the nature and destiny of man is marvelous....
The Addenda is as original as the book itself, consisting, as it does, of a list of names, some of whom are not subscribers, but to whom the author is deeply obliged, or whom he regards as very dear friends, and those of a few whom he personally admires.... If each of them has a copy of Etidorhpa, or the End of the Earth, he possesses a book which is not like any other book in the world.

It relates to a journey made by the old man under the guidance of a peculiar being into the interior of the earth. The incidents of this journey overshadow any thing that Verne ever wrote in his palmiest days. But perhaps the most singular part of it is that they are all based on scientific grounds. Dr. Lloyd, the author of the volume, is one of the deepest students, and is well known as a profound writer on subjects pertaining to his profession, as well as one who has taken much pains in studying the occult sciences.... The book is a very pleasant one to read, a little redundant at times, but full of information.... Readers who succeed in securing it will be very lucky indeed.
