This report is a further study on the previous report. In the previous report, it was assumed that the dissolving phenomena of various ions in glasses into the water followed Moriya's theoretical equation, and the data was examined quantitatively. In this report, it is assumed that the dissolving phenmena follow Douglas' equation, and they are tested by analysis variance. The conclusions are as follows. 1) The dissolving phenomena of P conform accurately to the theoretical equation, that is, log of the dissolving amounts of P vary linearly with log of the dissolving time and they are linear function of reciprocal of absolute temperature. 2) The dissolving phenomena of V and Ba are not in accordance with the theoretical equation as a whole, but they obey approximately the equation in some case, and in several case they obey exactly the equation. 3) Log of concentration of H ion in aqueous solution containing various ions dissolved from glasses varies linearly with log of stirring time and reciprocal of absolute temperature in the case of VO_<2.5> 40 mol. 4) Generally theoretical equations give the exact description of dissolving phenomena in the case of VO_<2.5> 40mol.
