It's being Northerners that really has been such a drawback." "But your sympathies," urged Faraday, "aren't they with the North?" Miss. Ryan ran the pearl fringe of her tea-gown through her large, handsome hands.
It will also be useful, in order to avoid confusion, to restate with precision this notion of electrolytic ions, and to ascertain their magnitude, charge, and velocity. The two classic laws of Faraday will supply us with important information. The first indicates that the quantity of electricity passing through the liquid is proportional to the quantity of matter deposited on the electrodes.
One of these youths may also go to Albermarle Street to hear Mr Faraday lecture on chemistry, or to Willis's rooms to hear Mr Carlyle lecture on German literature. On the Sunday he goes perhaps to church, perhaps to the Roman Catholic chapel, perhaps to the Tabernacle, perhaps nowhere.
Faraday made, in some sort, an equivalent discovery when he perceived that the electrical energy belongs, not to the coatings of the condenser, but to the dielectric which separates them. His audacious views revealed to him a new world, but to explore this world a surer and more patient method was needed.
In 1817, when lecturing before a private society in London on the element chlorine, Faraday thus expressed himself with reference to this question of utility. 'Before leaving this subject, I will point out the history of this substance, as an answer to those who are in the habit of saying to every new fact. "What is its use?" Dr. Franklin says to such, "What is the use of an infant?"
Faraday, studying the laws of electricity, discovered the principle which rendered the dynamo possible. Maxwell, Henry, and Hertz, equally unconcerned with material advantage, made wireless telegraphy practicable.
It's disgraceful, Mr. Faraday," said Mrs. Ryan, smiling brightly "disgraceful!" Faraday said he had heard that in the East the hostess made the same complaint. Mrs. Ryan, with brilliant fixed eyes, gave him a breathing-space to reply in, and then started off again, with a confirmatory nod of her head: "Precisely, Mr. Faraday just the case here. At Genevieve's début party an elegant affair Mrs.
But to-day we go back to Young, and see that he demonstrated it beyond question. In the third place, take another fact. Between 1830 and 1845 Faraday worked out a theory of electrical and magnetic phenomena. It was proved to be correct.
The preceding are but some of the results that Faraday obtained by means of his experimental researches in the direct production of electricity from magnetism. Let us now briefly examine just what he was doing, and the means whereby he obtained electric currents from magnetism.
If you earnestly contemplate the important adjuncts to applied science which have sprung from that apparently simple fact, you will not fail to see the importance of the discovery; for it was while working in this new field of electro-magnetism that Sturgeon made the first electro-magnet, and Faraday many of his discoveries relating to induction.
