‎First edition, off-print, of the seminal paper that contains the first enunciation of the thermochemical affinity principle and the introduction of the term ""varmetoning"". The present paper represents Thomsen's main work as well as the ""(to use Oswald's words) scientific creed of the chemist for the next half-century. It constituted the only method by which chemists could predict the course of chemical reactions, and Thomsen himself employed the theory in various ways to carry out calculations of this kind."" (Brøndsted in: Meisen edt., Prominent Danish Scientists Through the Ages, p. 143). This breakthrough work, which contains the first statement of a thermochemical nomenclatura and the first definition and presentation of the thermochemical affinity principle, inaugurated a several decades long period of thermochemical studies, during which Thomsen personally carried out more than 3,500 calorimetric measurements in a room kept at 18 degrees celcius. His fundamental thought was that the evolution of heat accompanying a chemical reaction (""varmetoning"") is an exact expression of the chemical affinity of the reaction. Bethelot reached many of the same conclusions a bit later and advanced a theory that in essence was the same as Thomsen's. This led to heated discussions that continued for several years between the two scientists. Thomsen's principle is now usually known as the Thomsen-Berthelot-Principle. In 1883, the Davy Medal was awarded in duplicate, to ""M. Marcellin Berthelot, Member of the Institute of France, and Foreign Member of the Royal Society, and Prof. Julius Thomsen, of Copenhagen"", although Berthelot was obviously preceded by Thomsen. ""The importance of Thomsen's scientific work was rapidly recognized in both Denmark and abroad. In 1860 he was elected member of the Royal Danish Academy of Sciences and Letters. Nine years later he was nominated as professor of physical chemistry at the University of Leipzig, but he refused the offer. Many foreign scientists asked to work under his guidance, but he was afraid that the comparability of the results obtained would be endangered when more than one person performed such measurements and therefore refused all such requests. Thus no school was formed around him. Thomsen was a foreign member of various academies and honorary member of learned societies, and held honorary doctorates from several universities (but not in France, because of the conflict with Berthelot)."" (D.S.B. XIII:359).""Julius Thomsen's international reputation is due largely to his thermochemical studies. He began to work on thermochemical problems in 1850, and in 1852 he published in the ""Videnskabernes Selskabs Skrifter"" a paper entitled ""Bidrag til et thermochemisk System"" [""Contributions to a thermochemical System""], in which he outlined the scheme of his subsequent thorough investigations in this field. This paper contains the first enunciation of the thermochemical affinity principle, which states that chemical affinity, or the attraction between substances, can be measured by the heat evolved when they combine.Ideas as to the nature and laws of chemical affinity were by no means lacking at this period, but the prevalent views were vague, hypothetical and mutually irreconcilable. The great importance of Julius Thomsen's principle when compared with earlier speculations lies not only in its fundamental theoretical ideas, which associate chemical and mechanical phenomena, but also in the fact that the conception of affinity is related to a measurable quantity, the ""Varmetoning"" - a term which Julius Thomsen introduced to include both evolution and absorption of heat - and thus is easily accessible to experimental investigation.""

‎First printing of a milestone paper in electrochemistry in which Davy shows that electricity is capable of decomposing the most stable elements.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806 (the paper offered here). His experiments, along the lines stated in this paper, lead to his discoveries of potassum and sodium in 1807 and the year after to barium, calcium and boron.(A Source Book in Chemistry p. 243). - Sparrow: Milestones of Science No 52. - Wheeler Gift: 2511.‎

He found that an electric current from a voltaic battery, which is readily conducted by water, did not pass through ice: even the thinnest film of iice, interposed in the circuit, was sufficient to intercept all electrical influence of such low intensities as that produced, by the voltaic apparatus, although it allows of the transmission of electricity of such high intensity that ecited by the common electrical machine. The author ascertained that a great number of other substances, which are solid at ordinary temperatures, do not conduct the electric current from the volataic battery until they are liquified."" (Abstract).From 1831 to 1852 Michael Faraday published his ""Experimental Researches in Electricity"" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other.""Among experimental philosophers Faraday holds by universal consent the foremost place.
