In the paper preceding this we have dealt with strain effects between like materials, and we now consider the case when the materials are unlike. The curves for zinc-ebonite (fig. 1) are of the same type as those for ebonite-ebonite (fig. 2 in the last paper) but the charges are now much larger and change sign with fewer rubs. Both these effects are to be expected: the first, because the two materials are chemically different; the second, because zinc is relatively hard and will very quickly develop full strain on the softer ebonite. The ratio of the rubbing areas is 1:45.
