The temporal variation of current in polar dielectrics such as acetone, nitrobenzene, $n$-propyl, isobutyl and isoamyl alcohol shows that initially the current falls very rapidly and then slowly and finally approaches a saturation value. Assuming the existence of free ions in the liquid the quantitative theory advanced by Gemant has been further developed. The theory explains very satisfactorily the observed variation of current with time and enables us in conjunction with experimental results to calculate the mobility and charge density of the ions. The mobility is of the same order of magnitude as that of weak electrolytes and the ion density is found to be of the order of $10^{15}$ to $10^{16}$ ions/cc in agreement with the results obtained earlier.
