After paying tribute to the names of Amos Kendall, Cyrus Field, Volta, Oersted, Arago, Schweigger, Gauss and Weber, Steinheil, Daniell, Grove, Cooke, Dana, Henry, and others, he continued:
I made an excursion to Copenhagen in the summer of 1856, as a sort of devout pilgrimage to the tombs of two renowned Danes, whose labors in their respective departments the one, Oersted, of science, the other, Thorwaldsen, of art have so greatly enriched the world.
Akin to these stolen titles are those which have been imitated, that is to say, stolen to the extent of one half; for instance, long after I had produced my treatise On Will in Nature, Oersted wrote a book entitled On Mind in Nature.
All those works on Natural Science, by Alexander von Humboldt, Oersted, Du Bois-Raymond, Cotta, Vogt, Moleschott, Büchner, Rossmässler, Ule, Müller, and others, which have appeared since the Revolution of 1848, uniting a more popular and intelligible style with a purely scientific treatment of the matter-of-fact, irrespective of the religious and political dogmas that conflict with the results of natural science, have met with decided success in Germany and France.
Ampere of Paris, following Oersted, promptly showed that two parallel wires carrying currents attracted each other when the currents flowed in the same direction, and repelled each other when they flowed in opposite directions.
THE ROYAL SOCIETY OF LONDON. If I were to attempt to do justice to the merits of this great society, I should have to devote many pages, to such subjects as the achromatic telescope of Dollond; the dividing engine of Ramsden, which first gave precision to astronomical observations, the measurement of a degree on the earth's surface by Mason and Dixon; the expeditions of Cook in connection with the transit of Venus; his circumnavigation of the earth; his proof that scurvy, the curse of long sea-voyages, may be avoided by the use of vegetable substances; the polar expeditions; the determination of the density of the earth by Maskelyne's experiments at Scheliallion, and by those of Cavendish; the discovery of the planet Uranus by Herschel; the composition of water by Cavendish and Watt; the determination of the difference of longitude between London and Paris; the invention of the voltaic pile; the surveys of the heavens by the Herschels; the development of the principle of interference by Young, and his establishment of the undulatory theory of light; the ventilation of jails and other buildings; the introduction of gas for city illumination; the ascertainment of the length of the seconds-pendulum; the measurement of the variations of gravity in different latitudes; the operations to ascertain the curvature of the earth; the polar expedition of Ross; the invention of the safety-lamp by Davy, and his decomposition of the alkalies and earths; the electro-magnetic discoveries of Oersted and Faraday; the calculating-engines of Babbage; the measures taken at the instance of Humboldt for the establishment of many magnetic observatories; the verification of contemporaneous magnetic disturbances over the earth's surface.
The streets in S/dermalm ascend by flights of wooden steps up from the M lar lake, which is all active with smoking steam-vessels, and with boats rowed by women in gay-colored dresses. I had brought with me a letter of introduction from Oersted, to the celebrated Berzelius, who gave me a good reception in the old city of Upsala. From this place I returned to Stockholm.
Many persons in my place would, like me, have fallen ill, or would have resented it vehemently: perhaps the latter would have been the most sensible. At my departure, many of my young friends amongst the students prepared a banquet for me; and amongst the elder ones who were present to receive me were Collin, Oehlenschl ger and Oersted.
Before the winter of 1815, however, it was a belief that was surmised but not demonstrated. But in that year it occurred to Jean Christian Oersted, of Denmark, to pass a current of electricity through a wire held parallel with, but not quite touching, a suspended magnetic needle. The needle was instantly deflected and swung out of its position.
Then arose the man who added to the powers of his intellect all the graces of the human heart, Michael Faraday, the discoverer of the great domain of magneto-electricity. OErsted discovered the deflection of the magnetic needle, and Arago and Sturgeon the magnetization of iron by the electric current.
