(Thermionic) Emission from Hot Bodies

Includes considerations of a general character, theory of the emission of electrons from hot bodies, temperature variation of electron emission, the effect of gases on the emission of electricity, energetics of electron emission, the emission of positive ions by hot metals, the effect of gases on the liberation of positive ions by hot metals, the emission of ions by heated salts, ionization and chemical action, and the emission of electrons under the influence of chemical action.
