The whole volume present: 448 pp. and 3 folded engraved plates. First French translation and the first translation of Oersted's epoch-making announcement in his Latin pamphlet "Extperimenta circa effectum conflictus electrici in acun magneticam. Hafniæ 1820" privately printed in a very small number and only distributed to colleques in Europe. This discovery and confirmation of the connection between 2 forces electricity and magnetism must be considered one of the happiest events in the history of science both with regard to scientific and practical results. - "From the moment that Ørsted's discovery became known it created an enormous sensation. The results communicated were so astounding that they were received with a certain distrust but they were stated with such accuracy that it could hardly be permitted to entertain any doubts. In the course of a short time the treatise was translated into all the chief languages." Kirstine Meyer. - Dibner:61 - PMM: 282 - Horblitt: 3 b. - Sparrow: 152. hardcover

First apperance of the papers in which Nilson describes his discovery of a new element and its properties and naming it Scandium. It was the second new element found after Mendeleev's prediction of its existence as "Eka-Boron"."Mendeléeff had predicted that another element which he called eka-boron and which he said would have an atomic weight between 40 calcium and 48 titanium would some day be revealed. It was discovered in 1879 by Lars Fredrik Nilson. Nilson extracted 63 grams of the rare earth erbia from gadolinite and euxenite and converted it into the nitrate. Upon decomposing this salt by heat as Marignac had done he obtained some very pure ytterbia and to his great surprise an earth that was unknown to him.Upon thoroughly investigating this new earth he found that it contained an element whose properties concided almost exactly with those Mendeléef had predicted for ekaboron. Nilson called it scandium in honour of his fatherland."Weeks "Discovery of the Elements" pp. 219-20.Parkinson "Breakthroughs" 1879 C. unknown

In 1841 Matteucci presented. a paper which showed that a galvanometer indicates a curring flowing whenh it is connected from the surface of a muscle to a wound in the muscle a current that was later called the "current of injury" and also the "current of rest" since it flowed without observable muscular contraction. Johannes Müller showed tis paper to his brilliant pupil du Bois-reymond. Du Bois interest was caught at once.

Pp. 245-266 a. 1 engraved plate ad. p. 251. Clean and fine. First appearance of a groundbreaking paper in chemistry in which Lomonosov describes his discovery of the transition of a metal into passive state and this is the first scientific description of this phenomena. He observed and described fast termination of the dissolution of iron in concentrated nitric acid and attributed this to a change in the solvent properties."Lomonosov employed corpuscular mechanics in chemical explanations more extensively than Boyle had done. Treating chemical compounds as particles in adhesion he held that "adhesion is eliminated and renewed by means of motion.since no change in a body can take place withouy motion". He attempted to apply these theories to chemical phenomena - although he was limited to speculation- in papers on the action of chemical solvents in general."DSB VIII p. 469."Lomonosov was founder of Russian science and he would be universally recognized as a great pioneer of science had he been born a West European. He was famous also for his literary works including poems and dramas. In 1755 he wrote a Russian Grammar that reformed the language and in the same year he helped found the University of Moscow. In 1760 he published the first history of Russia."Isaac Asimov. unknown

First appearance of this milestone paper in chemistry physics and astronomy announcing the discovery of helium in the sun and naming it 'helium' for Helios the Greek God of the Sun. In the same paper he demonstrates his invention of the spectroscope by which the prominences of the sun could be observed and studied without an eclipse by leading the light from the very edge of the sun through a prism. - Helium was not discovered on the earth before 1895 by William Ramsay and it was Crookes who established its identity with the helium Lockyer observed in the spectrum of the sun."This the last discovery was announced on the same day by the French astronomer Janssen who was in India observing a total eclipse. As a result the French government some ten years later struck a medallion showing the heads of both scientists.By that time the two men had made a much more dramatic discovery at the same time this time in cooperation. Janssen studying the spectrum ofthe sun during the eclipse had noted a fine line he did not recognize. he send a report on this to Lockyer an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements concluding that it must belong to a yeat unknown element possibly not even existing on the earth. He named the element from the Greek word for the sun."Asimov. unknown

Leibniz' 2 papers on the catenary curve paper 1-2 offered here was written at the instigation of Jacques Bernoulli. Following the example of Blaise Pascal who had initiated in 1658 a contest for the construction of the cycloid Leibniz also provoked the geometers of his time by challenging them to submit at the fixed date of mid-1691 their geometric method for the construction of the catenary curve. Leibniz later provided the answer followed by Johann Bernoulli and Huygens.'These two papers are a historical account of the origin of the study of this transcendental curve and at the same time the first physical-geometric construction showing the species-relationship between the catenary and the logarithmic curves as two companion curves; one arithmetic the other geometric. All of the differentials of the catenary curve are arithmetic means of corresponding differentials of the logarithmic curve; and all of the differentials of the logarithmic curve are geometric means of the catenary.'"The Catenary is the form of a hanging fully flexible rope or chain the name comes from "catena" which means 'chain' suspended on two points. The interest in this curve originated with Galileo who thought that is was a parabola. Young Christiaan Huygens proved in 1646 that this cannot be the case. What the actual form was remained an open question till 1691 when Leibniz Johann Bernoulli and the then much older Huygens sent solutions to the problem to the "Acta" Jakob Bernoulli 1690 Johann Bernoulli 1691 Huygens 1691 and Leibniz 1691 - these 4 1691-papers offered here - in which the previous year Jakob Bernoulli had challenged mathematicians to solve it. As published the solutions did not reveal the methods but through later publications of manuscripts these methods have been known. Huygens applied with great paper 4 virtuosity the by then classical methods of 17th century infinitesimal mathematics and he needed all his ingenuity to reach a satisfactory solution. Leibniz the papers 1-2 and Bernoulli paper 3 applying the new Calculus found the solutions in a much direct way. In fact the catenary was a test-case between the old and the new style in the study of curves and only because the champion of the old style was a giant like Huygens the test-case can formally be considered as ending in a draw." Grattan-Guiness in "From the Calculus to Set Theory 1630-1910.".The paper by JACOB BERNOULLI no. 5 offered here is a milestone papers as it marks the invention of the "SYSTEM OF POLAR COORDINATES" with points located by reference to a fixed point and a line through that point. Although newton had earlier also devised such a coordinate system in 1671 his work was not known so that the credit for the discovery generally goes to Bernoulli.

A larger paper on the discovery was published in 1877 in "Annales de Chimie et Physique". In 1879 Bausbaudran was awarded the Davy Medal for his discovery of Gallium. "In 1875 Boisbaudran spectroscopically discovered a new element gallium which he found in zinc blende from a mine in Hautes-Pyrénées. Continuing his work in Wurtz’s laboratory in Paris he was a able to obtain the free metal by electrolysis of a solution of the hydroxide in potassium hydroxide. Gallium Boisbaudran realized was the "eka-aluminum" predicted by Mendeleev and was the first of Mendeleev’s predicted elements to be isolated. Boisbaudran’s finding thus provided valuable evidence for the validity of Mendeleev’s periodic classification of the elements."DSB."Lecoq de Boisbaudran announced his discovery by spectroscopic analysis of the new element gallium. Mendeleev had first predicted its existence and had named it eka-aluminium. The discovery was made in the author's private laboratory in a specimen of zinc blende from the Pierrefitte mine in the Angelès Valley in the Hautes Pyrénées. He describes how on the evening of 27 August 1875 he detected the existence of this new element which he named "gallium" in honor of France Gallia. A month later he "performed in Wurtz's laboratory in Paris.a series of experiments to prove that gallium.is a true element"Weeks. he discusses how he eventually isloated small amounts of pure metallic gallium and determined its physical and chemical properties. The paper the paper offered first describes gallium compounds e.g. ammonium gallium alum chloride oxide and sulphate."Roy G. Neville II p. 29. unknown
