[MENELEEV, Dmitri] "Professor Mendeleeff on Argon". In: NATURE, April 4, 1895, volume 51 #1327, page 543 in the weekly issue of pp 529-552. Includes the original wrapper. The whole weekly issue has been detached from a larger bound volume; the issue is intact, with a working spine, though the wrappers part of it are detached from the issue though together in themselves. Provenance: Smithsonian Astrophysical Observatory. Good copy. __+__ "In 1904, Lord Rayleigh (1842 1919) and his collaborator Sir William Ramsay (1852 1916) were awarded the Nobel Prize in physics and chemistry, respectively, primarily for their role in the discovery of argon, an inert gas in the atmosphere. The averse reaction to this discovery by Mendeleev (1834 1907) might have been the main reason for his not being awarded the Nobel prize in chemistry in 1906." The discovery of argon resulted from a careful unraveling of an empirical discrepancy, initially detected by Rayleigh when measuring the density of nitrogen gas produced by two different procedures. After a long trial-and-error process based on a carefully designed sequence of experiments and guided by an informal (by today s standards) analysis of the resulting data Rayleigh and Ramsay reached the conclusion that the atmospheric air contains argon, a hitherto unknown element."--"The Discovery of Argon: a Case of Learning from Data?", by Aris Spanos in Philosophy of Science,Vol. 77, No. 3, July 2010__+__ "Rayleigh and Ramsey  had noted that nitrogen obtained from the air had a density greater than that of nitrogen liberated from its compounds by about one-half percent. This led to the isolation of the first of the inert gases which they called argon. In the following year Ramsay found another, helium, in the mineral clevite, altho this had been noted in the sun s spectrum by Lockyar  in 1868. In four years, 1894-8, five new gases, including neon, krypton and xenon had been discovered. These form a distinct group in the periodic table; all have zero valency. [Dibner]. Dibner, Heralds of Science 50.__+__ Mendeleev was famously circumspect about the discovery of argon as it did not form a fit with the periodic table and briefly challenged its legitimacy; I short order though argon proved to be one of the most celebrated cases in proving its efficacy.
