Synopsis: From Nature, Nov. 28, 1895, courtesy of Google Books: This remarkable book bears upon every page evidence of scientific knowledge and vivid imagination. It is not simply a story of a journey to our satellite—that idea has been worn to threads since Jules Verne used it for the ground-plan of his novel—but purports to be a translation of a volume written by a lunar inhabitant, and sent to the earth. More than one ingenious individual has suggested that the side of the moon remote from us is inhabited; and as we are not likely to obtain more information on the matter, every one is free to indulge in that belief. The idea that there are living beings in the moon's interior, is of a similar harmless character, and the author of this book has made the most of it. Down in the interior of the moon, and near the center, dwelt a race of people--the Sarava—who believed that the universe was an illimitable extent of solid rock, honeycombed throughout with endless tunnels and caverns. But a man arose—a lunar Copernicus—who expounded the doctrine that the place which the Sarava occupied was merely a lump of cavern-hollowed rock suspended in an infinite vacant space. A Prince of the Sarava sets out with two companions in the hope of reaching the surface, and their expedition is successful. Wit the adventures of the explorers, we have nothing to do, nor is it for us to analyze the sentimental undercurrent. The attractive parts of the story, from the scientific point of view, are those which show the author's acquaintance with electromagnetic waves and the ether. He makes the Sarava possess machines to etherealize matter, so that by placing two powerful electromagnetic foci at any distance apart, it was possible to transmit objects or people from one to the other with the velocity of light; the object being etherealized at one focus, projected to the other, and then by a similar series of electromagnetic waves, converted into its material state. Having reached such a high state of knowledge of the ether, it is hardly necessary to say that the Sarava could see and speak with one another at a distance, without the necessity of connecting wires, and had also managed to tap the ether and use its terrific energies in destructive weapons. How very intelligently, and with what regard to known facts these imaginary machines are constructed, can only be appreciated by a perusal of the book. We congratulate the author on the skillful and original way in which he has handled an old subject.
