hears every word distinctly, and readily detects the modulations of the speaker’s voice.” Thus, in the presence of such wonderful discoveries of our age, and the further magical possibilities lying latent and yet undiscovered in the boundless realm of nature, and further, in view of the great probability that Edison’s Force and Professor Graham Bell’s Telephone may unsettle, if not utterly upset all our ideas of the imponderable fluids, would it not be well for such persons as may be tempted to traverse our statements, to wait and see whether they will be corroborated or refuted by further discoveries. Only in connection with these _discoveries_, we may, perhaps, well remind our readers of the many hints to be found in the ancient histories as to a certain secret in the possession of the Egyptian priesthood, who could instantly communicate, during the celebration of the Mysteries, from one temple to another, even though the former were at Thebes and the latter at the other end of the country; the legends attributing it, as a matter of course, to the “invisible tribes” of the air, which carry messages for mortals. The author of _Pre-Adamite Man_ quotes an instance, which being given merely on his own authority, and he seeming uncertain whether the story comes from Macrinus or some other writer, may be taken for what it is worth. He found good evidence, he says, during his stay in Egypt, that “one of the Cleopatras (?) sent news by a wire to all the cities, from Heliopolis to Elephantine, on the Upper Nile.”[230] It is not so long since Professor Tyndall ushered us into a new world, peopled with airy shapes of the most ravishing beauty. “The discovery consists,” he says, “in subjecting the vapors of volatile liquids to the action of concentrated sunlight, or to the concentrated beam of the electric light.” The vapors of certain nitrites, iodides, and acids are subjected to the action of the light in an _experimental tube_, lying horizontally, and so arranged that {128} the axis of the tube and that of the parallel beams issuing from the lamp are coincident. The vapors form clouds of gorgeous tints, and arrange themselves into the shapes of vases, of bottles and cones, in nests of six or more; of shells, of tulips, roses, sunflowers, leaves, and of involved scrolls. “In one case,” he tells us, “the cloud-bud grew rapidly into a serpent’s head; a mouth was formed, and from the cloud, a cord of cloud resembling a tongue was discharged.” Finally, to cap the climax of marvels, “once it positively assumed the form of a fish, with eyes, gills, and feelers. The twoness of the animal form was displayed throughout, and no _disk, coil, or speck existed on one side that did not exist on the other_.”
