Ernst von Meyer in History of Chemistry. For this discovery Lord Rayleigh and W. Ramsay received the Nobel Prize 1904. The volume also contains WILLIAM CROOKES "On the Spectra of Argon" OSBORNE REYNOLD "On the Dynamical Theory of Incompressible Viscous Fluids and the determination of the Criterion" KARL PEARSON "Contributions to the Mathematical Theory of Evolution. - II. Skew Variations in Homogenous Materials" etc.After having made several measuring of the densities of gases "Rayleigh came across a curious puzzle. With oxygen he always obtained the same density regardless of how the oxygen might be produced whether from one particular compound from a second compound or from the air. The situation was different with nitrogen. The nitrogen he obtained from air constantly showed a slightly higher density than the nitrogen he obtained from any of various compounds. Rayleigh could think of several ways in which the nitrogen obtained from air might be contaminated but none of the possibilities checked out experimentally. He was so frustrated that he went so far as to write to the journal "Nature" asking for suggestions. Ramsay a brilliant Scottish chemist asked permission to tackle the problem and received it. The upshot was that a new gas somewhat denser that nitrogen was discovered to exist in the atmosphere. It was named argon and it was the first of a series of rare gases of unusual properties whose existence had never been suspected."Asimow.Dibner Heralds of Science No. 50 - Neville Historical Chemical Library vol.
