In a previous paper by the author the value of the “radiation constant” of the Stefan-Boltzmann law was obtained, using an apparatus which fulfilled the condition of a full receiver; all previous determinations being open to objection on the ground that this condition was not attained. The “emitter” used in that investigation and maintained at a temperature of 1100° C. was of the usual type—a modified form of Heræus furnace; but it was pointed out at the time that such a radiator is by no means a uniform temperature enclosure, and that the author intended to construct such an enclosure which would approximate more nearly to the ideal full radiator. The value of the radiation constant is open to criticism until it has been determined with apparatus in which both “emitter” and “receiver” fulfil “black body” conditions.
