1837 W. Whewell II. ix. ix. 384 The effect which the mica produced was termed depolarization; —not a very happy term, since the effect is not the destruction of the polarization, but the combination of a new polarizing influence with the former. The word dipolarization, which has since been proposed, is a much more appropriate expression.
