1. An apparatus was built to follow the decomposition of benzene-diazo-acetate in solution by measuring the pressure of the nitrogen evolved in a constant volume system - the evolution of air from solution occurred simultaneously due to an initial decrease in pressure to protect the system. One of two otherwise similar cells was fitted with electrodes for application of an electric field. 2. The rate of pressure increase for a concentration of 0.4 g. per 1. was greatly accelerated by an electric field of 3000 volts per cm. and 1.5 megacycles. The effect of the field decreased rapidly as the concentration was increased, and at 1.6 g. per 1. the acceleration was barely discernible. The greatest effect was obtained for the gas evolution alone. [...]
