Abstract
DURING an experiment in which an attempt was being made to get atomic hydrogen by means of an incandescent tungsten filament in wet hydrogen, a quite unexpected glow was discovered. The apparatus consisted of a three-litre bulb in the bottom of which there was sealed a tungsten filament from a 300-watt electric-light bulb. The pressures varied from 2 cm. to 35 cm., the hydrogen being generated by the electrolysis of potassium hydroxide. No care was taken to dry the hydrogen or to purify it.
