It has been shown by the present writer in conjunction with A. Parker that the ionisation which is produced by carbon at high temperatures, and in presence of gases at low pressures, is reduced to a much smaller order of magnitude by eliminating impurities from the carbon, and by exhausting to a high degree the containing vessel. The results threw considerable doubt on the whole basis of the theory of electronic emission from incandescent solids.
