    (1) The glow-discharge between the metallic cathode and the surface of the solution was examined, and it was found that the products were mostly hydroxides or oxides of the cations in the solution. From the coulomb-efficiencies of their formations and the products obtained by the glow-electrolyses with the solutions covered with oil, it was concluded that the decomposition of water molecules should occur at the surface of the solution and it should be caused by the impacts of the electrons or other particles having enough energies to dissociate the water molecules.
    (2) A characteristic phenomenon by the transportation of the negative electricity through the boundary of the gas and the solution was studied and it was deduced that the dissociation should be caused by the accelerated electrons having the kinetic energy of 23.8 e.v..
    Further, the process of the dissociation was proposed, and the energy required for this dissociation was calculated as 23.1 e.v..

    One spear-head and three halberds which are of the same types as those relics unearthed from Yin Site, were analysed, and it was proved that the spear-head and the two of three halberds must be called the copper implements, and the last one of the halberds contains a considerable amount of tin, therefore this specimen may be called properly a bronze one.
    Considered from these results coupled with those described in the previous two papers, all of four spear-heads already studied were of almost pure copper, and four of the six halberds were also pure copper implements and some others were regarded as bronze implements.
    Thus, by the present investigation of the author, the existences of the copper age and a transitional period to the bronze age in ancient China were further emphasized.

    (1) The monochromatic light of about (λ=) 520μμ was passed through nitrobenzene which was put in crossed nicols and in an alternating electric field of 7,000–25,000 volts/cm., and the intensity of light from the analyser was measured.
    (2) The potential of the electric field was calculated from the measured intensity of light by using the known Kerr constant.
    (3) The calculated values of potentials are nearly equal to those obtained from the turn ratios of the transformer, but are generally less than the latter.
