‎All papers first apperance. All 5 of extreme importence in the development of the Calculus. 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.

He further gives arguments for considering potassium and sodium, which he discovered in 1808, as a element.""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 lectures."" - Wheeler Gift: 2518.‎

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).‎

With that discovery, it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier, in 1800, William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum, Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum, but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum, in a region where no sunlight was visible. To his amazement, this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light, which Ritter called Chemical Rays, later became known as ultraviolet light or ultraviolet radiation (the word ultra means beyond). - Parkinson, Breakthroughs: 1801 P.‎

In october 1836 Wöhler wrote that he had discovered a way to transform amygdalin to oil of bitter almonds and hydrocyanid acis, by distilling it with manganese and sulfuric acid, and he invited Liebig to join in pursuing the topic. Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds, in a manner similar to the action of yeast in sugar...Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance ""emulsion"".

‎Ueber elektro-dynamische Induction.‎

‎(Leipzig, Johann Ambrosius Barth, 1842). Without wrappers. In ""Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff"", Ergänzungsband 1, Stück 2. Pp. 193-384 a. 1 folded engraved plate. (The entire issue offered). Henry's paper: pp. 282-312.‎

‎First German version of Henry's description of his discovery of self-induction. He missed the credit for the discovery of induction to Faraday, but he had done the key experiment ahead of Faraday, but Faraday was the first to publish. But he is credited for the discovery of self-induction (1832) and Faraday discovered it independently two years later (1834).""In Henry's paper, however, he explained thet the electric current in a coil can induce another current not only in another coil but in itself. The actual current observed in the coil is, then, the combination of the original current and the induced current. This is called self induction.""(Isac Asimov).The issue contains further notable papers Michael Faraday's ""Vierzehnte Reihe von Experimental-Untersuchungen über Elektricität"", 2o-22. (Nos 1667-1748). Pp. 249-281. First German version. In this paper FARADAYamplifies his theory of electrostatic induction by making further use of the analogy with the induction of magnetism. Whittaker describes the paper as having ""THE FUNDAMENTAL EQUATION OF ELECTROSTATICS"", as modified in order to take into account the effect of the specific inductive capacity.""(Whittaker I, pp.187-89).‎

‎First appearance of the paper in which Ramsay and Travers announced their discovery of a new element which they named ""krypton"" (meaning hidden).""Dr. William Hampson presented them (Ransay & Travers) with about a liter of liquid air, which they used, not for liquefying the argon, but for obstaining sufficient skill in manipulation so that they would not risk loosing their precious fifteen liter of argon......The residue left after most of the liquid air had boliled away consisted largly of oxygen and nitrogen, which Ramsay and Travers temoved with red-hot copper and magnesium. ....(they) then examined the twenty-five cibic centimeters of residual gas, and when they found it to be inerst, they immediately placedit in a Pl'ucker tube connected to and induction coil and observed its spectrum. There was a bright yelælow line with a greener tint than that of the helium line and a brilliant green line that did nor coincide with any line of argon, helium, mercury, or hydrogen. They discoverede this gas on 30 May, 1898, and named it 'krypton'....they found that it belonged between bromine and rubidium in the periodic table, and so great was their excitement that the younger chemist almost forgot about his examination for doctor of sciwence which had been schedules for the next day.""(Weeks, p. 267).Parkinson ""Breakthroughs"", 1898 C.‎

Davy was chemically preparing Potassium and Sodium through an electrical current, and this made Gay-Lussac and Thénard envious of his success. They too decided to perform the same task, but they had no battery at their disposal as Davy had, so they had to form another way to chemically prepare the two elements. In 1808, they used a red-hot iron fused to potash, the water-soluble form of a manufactured salt containing potassium, to perform this task, a method that Davy admitted had its advantageous qualities. Gay-Lussac and Thénard were successful in preparing Potassium, and continued to make a full analysis of its chemical properties, and began to use it for their own experiments. In 1809, Davy performed the same task, using it to reduce Boron in Boracic acid.""‎
