   • 1942, Proceedings of the Royal Society of London:

     The nitrogen used was freed from oxygen by standing moist phosphorus in the cold, and drying with phosphoric oxide. On the other hand, heating in oxygen or in air will not make it glowless, and if it is glowless initially it gives the glow again in full brightness after this treatment.
