Abstract

WE are enabled to state that the communication to the Royal Society on “Argon, a new Constituent of Air,” by Lord Rayleigh and Prof. Ramsay, to be given at the Royal Society to-day, will refer to the density of nitrogen from various sources; to methods for removing free nitrogen from air; to the separation of argon from air by diffusion; to the density of argon; to its spectrum (on which a short paper will be read by Mr. Crookes); and to its behaviour at low temperatures. It is interesting to note that Prof. Olszewski, of Cracow, has liquefied and solidified the gas, and will communicate a short paper on the subject. The solubility in water is also recorded. Various attempts to induce chemical combination are described, and general conclusions are drawn in a final section. The ratio of its specific heats shows it to be a monatomic gas, and proves that its atomic weight is approximately 40. The meeiing will not be held in the apartments of the Royal Society, but in the theatre of the University of London.
