We do not of course appear in this matter unless the post-mortem should indicate anything unusual in the circumstances of Duson's death, but it is always well to be prepared, and I ventured to ask Mr. Hertz here to procure for me your opinion as regards the death of your servant." "You have asked me," Mr. Sabin said gravely, "a very difficult question."
All the progress realised in the manner of producing and receiving these waves necessarily helped to give rise to the application already indicated. The experiments of Hertz, after being checked in every laboratory, and having entered into the strong domain of our most certain knowledge, were about to yield the expected fruit.
Guglielmo, their second son, had his early education at a private school in Bedford, England, and later at Livorno and Florence in Italy. When he read about the experiments of Heinrich Hertz and about Popov's suggestion, he saw the possibility of using these waves as a means of signaling. His first transmitter, shown in the accompanying photograph, did not radiate very far.
But the researches of Faraday, Maxwell, and Hertz authorized still greater ambitions; and it really seemed that this medium, to which it was agreed to give the ancient name of ether, and which had already explained light and radiant heat, would also be sufficient to explain electricity. Thus the hope began to take form that we might succeed in demonstrating the unity of all physical forces.
He cares very little for psychological exactitude or truth of observation; but he is the very type of what we mean by a verbal artist. Ibsen made acquaintance with the works, and possibly with the person, of Hertz, when he was in Copenhagen in 1852.
And Jo Hertz was again just the dull, grey, commonplace brother of three well-meaning sisters. Babe used to say petulantly, "Jo, why don't you ever bring home any of your men friends? A girl might as well not have any brother, all the good you do." Jo, conscience-stricken, did his best to make amends.
Space is all a-quiver with waves of radiant energy. We vibrate in sympathy with a few strings here and there with the tiny X-rays, actinic rays, light waves, heat waves, and the huge electromagnetic waves of Hertz and Marconi; but there are great spaces, numberless radiations, to which we are stone deaf. Some day, a thousand years hence, we shall know the full sweep of this magnificent harmony.
Passing the discharge from a condenser into this coil, Hertz discovered that the spark caused when the current jumped the gap set up electrical vibrations that excited powerful currents in the other coil. These currents were noticeable, though the coils were a very considerable distance apart. Thus Hertz had found out how to send out electrical waves that would travel to a considerable distance.
She got into her clothes, shaking with cold and terror, and yet thinking very clearly, as she always did in a crisis. She put clean towels in the bathroom, pushed the table up to the bed, got a glass of water, straightened the covers, put away the clothes that the tired woman had left about the room. Doctor Hertz came.
In a thoughtful lecture on the relations between light and electricity at the sixty-second Congress of German naturalists and physicians in Heidelberg in 1889, Heinrich Hertz explains the scope of his brilliant discovery: "Thus the domain of electricity extends over the whole of nature. It comes nearer to ourselves; we learn that we actually possess an electric organ, the eye.
