It has been shown by Beattie,* Garrett,j-and Garrett and Willows,J that when certain salts are heated up to 300-400° C. one can observe the discharge of positive and negative electricity. This phenomenon is observed more particularly in the case of the halogen salts of cadmium, zinc and ammonium. The researches of Schmidt § and Sheard|| have shown that the discharge is due to two factors, (1) emission of the charges from the surface of the heated salt, and (2) to the conductivity of the salt

RichardsonlT and his pupils, while some investigations of the electrical properties of the salt vapours were made by Schmidt in the papers referred to above. The object of the present research was to investigate the influence of the temperature, water vapour, time, etc., on the current passing in the salt vapours.
