With another instrument we are able, not only to hear but to converse audibly, as long as we like, with another human being a thousand miles away, who is also sitting comfortably in his own arm-chair and speaking to us with as much freedom as though we were both in the same room. With another instrument we can go further, and exchange thoughts, in a few seconds, with a being on the other side of the world, by means of a thin wire that is itself fixed, and does not move, and we have lately invented another means by which we can do the same, over several thousands of miles, without even a connecting wire. With another instrument we have gone far beyond the facility with which the Printing press enabled us to communicate our thoughts to our fellow human beings, we can actually imprint our very words and laughter upon a wax cylinder and send it to the antipodes, and our friends there, with a similar instrument, can not only hear and recognise our very voice, but can make that voice repeat our thoughts audibly, to a thousand others at the same time, and can repeat that process for hundreds of times without exhausting that voice. With another instrument we can depict on a film, not only the images of our friends but their very actions, which may also be sent to any distance, and the persons, thereon depicted, may be seen by their relatives alive and going about their everyday employments, with every movement exact to life. We can cross the Ocean against the wind and waves by means of harnessed sunbeams, without any exertion of our own, at the rate of an express train, which train, by the by, is also moved by the same means; we can dive to the bottom of the sea and journey there for hours, in perfect safety, without coming to the surface, and we are even developing wings, or their equivalent, which from immemorial tradition we were not to possess before we had finished doing our duty properly in this world and had gained admission to the next.
