‎First appearance in German of Ångström's famous paper in which he announced the discovery of hydrogen in the atmosphere of the sun and in which he also confirmed the probable existence of of other elements there. The paper appeared in ""Oefversigt af K. Vet. Acad. Förhandl."" in 1861. The German paper here is expanded. At the same time it was translated into English and publishe as ""On the Fraunhofer Lines Visible in the Solar Spectrum"".Ångström was one of the early formulators of the science of modern spectroscopy" he wrote extensively on terrestrial magnetism, the conduction of heat, and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter, a unit of length now known as the angstrom. He discovered that hydrogen is present in the sun's atmosphere, and he was the first to examine the spectrum of the aurora borealis. ‎

‎First appearance of a milestone paper in the history of electricity as Aepinus here found that a heated tourmaline attracted and repelled light bodies. He decided, that the effect was electrical and that its ends was carrying charges of opposite sign, much as soft iron is magnetized by a lodestone. This paper is a forerunner of his ""Tentamen Theoriae electricitatis et magnetismi"", - published 1759, and one of the most original and important books in the history of electricity. It is the first reasoned, fruitful exposition of electrical phenomena based on action-at-a-distance.""Aepinus’ first reseraches on the thermoelectric properties of this stone (Tourmalin) which was then of extreme rarity, were fundamental. He recognized the electrical nature of the attractive power of a warmed tourmaline and attempted not altogether successfully, to reduce its apparent capriciousness to rule. He was particularly struck by the formal similarity between the tourmaline and the magnet in regard to polarity which inspired him to reconsider the possibility, then occasionally discussed, that electricity and magnetism were basically analogous. This thought became the This thought became the theme for his masterwork, Tentamen theoriae electricitatis et magnetismi (1759).""(DSB).""Aepinus is known in the history of electricity for his attempt to develop the one fluid theory of Franklin. His theory was for a while generally adopted, but was gradually displaced by the two fluid theory, in consequence chiefly of the necessity of ascribing to uncharged matter repulsions of the same force as those which were ascribed to electrical charges. His theory exhibits interesting similarities to the present theory of the constitution of matter""(Magie ""A Source Book in Physics"", pp.406-8).Ronalds p. 4.‎

‎Scarce first edition of Hans Christian Oersted's first printed book (The Science of the General Laws of Nature). Oersted is universally known for his discovery of the Electro-Magnetism in 1820. In this his first printed book, Oersted proposes at least three theses that he were to follow for the rest of his life, and which he made the foundation for his discovery of Electro-Magnetism: the crucial role that experiments and thereby empiricism play in the perception of nature the fact that each individual phenomenon in nature in accordance with the philosophy of nature must be understood as a whole" and that the laws of nature are the same everywhere, in the smallest and in the greatest parts of the universe. The sort of philosophy of nature that Oersted studies and develops is by him comprehended as a product of human striving towards with its reason to ""include and penetrate the entire nature, and to explain it in its full context"" (from ""Science of the General Laws of Nature"" - own translation), which is why this philosophy is also the science of the general laws of nature (that are the same everywhere). It thus not only includes the science of movement, but also that of electricity, magnetism, light, warmth, and chemical connections, such as they all follow directly from ordinary forces of nature, and Oested's discovery in 1820 of the connection between magnetism and electricity must be seen in this connection.Both H.C. Andersen and Søren Kierkegaard admit to having been influenced by the writings of Oersted. ""He was an enthusiastic follower of the ""Naturphilosophie"" school in Germany, whose main object was the unification of physical forces, thus producing a monistic theory of the universe. It was to further this purpose that Oersted sought in actual phenomena the electro-magnetic identity of which he had already convinced himself on metaphysical grounds"" (Percy H. Muir in Printing and The Mind of Man). ‎

‎First appearance of this importent paper - which can bee seen as the precursor of OHM'S LAW - in which Ørsted explains the experiments he did together with Fourier on the thermo-electric effects discovered by Seebeck. They proved with different experiments, that the effect depended solely on the heating of the plates in the voltaic arrangements. Ørsted calls Seebech's observations ""the most beautiful of the discoveries which have as yet grown out of mine (his discovery of electromagnetism three years before)""""We learn from his letters that thet the experiments on which the paper was founded had taken him 3 weeks, a space of time which evidently much too short for the performance of the work" thus Ørsted himself points out a fundamental flaw in the experiments, but there has been no time to remedy it. The work is of interest, both by what has been gained through it, and by what does not plainly appear" in some of its results it is the precursor of Ohm's law and by its defects it shows how great was the feat of the actual discovery of this law.""(Kirstine Meyer).The offered issue contains further Poisson ""Sur le Phénomene des anneaux colorés"", pp. 337-347., Ørsted ""Sur le Multiplacateur électro-magnetique de M. Schweigger, et sur quelques applications qu'on en a faites"", pp. 358-365, Ampère ""Extrait d'une Lettre de M. Ampère à M. Faraday"", pp. 389-400.‎
