The present paper is a record of certain of the physical properties of solutions of silver nitrate and of ammonium nitrate, which were made by us in connection with our work on conductance. Some of these properties were actually used in calculations, others not, but they are collected here in their entirety. The properties described are: (1) normal boiling point; (2) densities and partial molar volume of water in solution; (3) viscosities at different concentrations and temperatures, as compared with those of a typical nonelectrolyte, urea; (4) the temperature coefficient of fluidity compared with the temperature coefficient of conductance; (5) the distribution coefficient of acetic acid between ether and solutions of silver nitrate.
