The temperature coefficients expressed in percentages, onthe other hand, invariably decrease with rise in fact that temperature coefficients of all salts increase withrise in temperature, whereas both organic and inorganic acidshave decreasing temperature coefficients, is easily explained 4o8 Jones and Jacobs on. by the hydrate theory of Jones. The metallic cations areprobably the ones that are chiefly hydrated in solution, andwhen the temperature is raised this hydration is diminished,thus greatly increasing the ionic mobility, while no such in-crease is possible where metallic ions are During the progress of this work^we noticed a strikingphenomenon in the telephone that should be short time after the circuit was closed, thus allowing thecurrent to pass through the cell containing the electrolyte, asudden increase in the loudness of the tone was noticed whenthe key was held near the node on the bridge. This phenom-enon was at first thought to be due to polarization, but later, Conductivity and Ionization of Electrolytes. 409 when the same effect could be obtained with any solution,even with redistilled water, and since no noticeable change inconductivity could be detected as a result of it, we concludedthat this phenomenon is novel in character, and as far as weknow has not been described before. The time for this loud-ness to come on varied from a few seconds to eight or tenminutes, depending upon the nature of the electrolyte. It is futile to speculate what might be its cause until moreexperimental evidence is obtained. On
