1905réf. 42829Leipzig S. Hirzel 1905. No wrappers. Issued in "Jahrbuch der Radioaktivität und Elekronik" 2. Bd. Heft 3. Hahn's paper: pp. 233-264. Enntire issue: pp. 233-262 = entire "Heft 3". Fine and clean. First printing of this paper which is Hahn's Habilitation paper announcung his discovery of a new element in residues from a Ceylon mineral called Thorianite. He later showed that it is an intermediate disintegration product."Because the sample thorianite was small Ramsay proposed that Hahn confirm Marie Curie's determination of the atomic weight of radium by preparing it in some organic compounds thereby greatly increasing the total amount being examined and calculating the atomic weight from the measured molecular weights. Chance sometimes favors the unprepared mind and Hahn who familiarized himself with only the basic of radioactivity followed the prescribed separationss technique and found himself the discovere of a new radioelement: radiothorium. The explanation was that the material given him came from an ore which contained a large percentage of thorium in addition to the radium. Thus upon completion of the chemical procedure not all the activity was confined in the radium-containg fraction; indeed the nes subsyance in the remainder was several hundred thousand times more active than thorium and ultimately yielded the characteristic one.minute halflife of thorium emanation."DSB VI p. 15. - Weeks Discovery of the Elementsp. 308 ff. unknown

1803réf. 43638Halle Rengerschen Buchhandlung 1803. Without wrappers as extracted from "Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert" Jahrgang 1802 Bd. 12 Zwölftes Stück. Pp. 409-416. Titlepage to vol. 12. This is Ritter's first expositon of his discovery of ultraviolet light. It was announced the year before in a halfpage letter addressed to Gilbert's Annalen and printed in the Annalen. 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. unknown

The history of its discovery was very complicated as some other laid claim to its discovery.Stromeyer was inspector general of apothecaries in Hannover. "In 1817 fulfilling the duties of his office he came across an apothecary's shop in which a bottle labeled zinc oxide contained zinc carbonate. Following this up Stromeyer found himself interested in zinc carbonate which turned yellow on strong heating as though it contained iron as an impurity yet it contained no iron. He traced the yellow to an oxide not of zinc but of a hitherto unknown metal rather like it chemically. He named it cadmium for a zinc ore in which it is usually found accompanying the zinc."Asimov.Weeks "Discovery of the Elements" pp. 135-39. unknown

First apperance of Villard's two papers in which he announced and described the discovery of a new type of radiation more powerfull and penetrating than alpha-and beta rays. The new type of rays was named by Rutherford as gammarays."His Villardexperiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic EM like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts."

The papers were issued at the same time in "Annalen der Physik und Chemie"."The conclusions which you have drawn from the investigation of bitter-almond oil" wrote Berzelius to Liebig and Wöhler "are certainly the most importent which have so far been reached in the domain of vegetable chemistry and give promise of shedding an unexpected light over this part of the science.The facts which you have set forth inspire such reflections that they may be regarded as the dawn of a new day in vegetable chemistry."Berzelius-Wöhler Briefwechsel."During the years that Liebig was preoccupied with the ether theory and with organic acids he also carried out two importent investigations with Wöhler. 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". Its effectiveness in very small quantities confirmed that it acted like yeast."DSB VIII p. 342. unknown

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. unknown

At his suggestion Vauquelin made some very careful chemical analyses of these two minerals and found in 1798 that they are indeed identical and that they contain a new earth which he named glucina but which is now known as beryllia.

First printing of the papers in which Vauquelin describes and announces his discovery of Chromium. The first paper was simultaneously printed in Mem.de l'Institut. Because of its many coloured compounds Fourcroy and Haüy suggested the name 'chromium' for the new metal. Greek chroma-colour.In 1797 Vauquelin began his own studies of Siberian red lead. He was convinced that the mineral contained a new element. None of the elements then known could account for his results. He reported "a new metal possessing properties entirely unlike those of any other metal." A year later Vauquelin was able to isolate a small sample of the metal itself. He heated charcoal nearly pure carbon with a compound of chromium chromium trioxide Cr 2 O 3 . When the reaction was complete he found tiny metallic needles of chromium metal.
