Abstract
IN a letter recently published in NATURE of October 30, 118, p. 625, Prof. Baly and Dr. Riding gave an account of their more recent experiments on the appearance of the rare gases in electric discharge tubes. Under certain conditions they found both neon and helium in the residual gas, and they record one instance in which pure helium was obtained. These results confirm their earlier observations, as well as those of Collie, Patterson, and Masson (1915). The authors incline to interpret their results as due to a disintegration by the electric discharge of the nitrogen atom, the experiments having been performed in mixtures of oxygen and nitrogen, or with nitride electrodes.
