With three external electrodes, and proceeding on the ABC plan, to test the separate unipolar effects at A and at B (p. 69), the antidrome-anodic effect has sometimes exceeded and sometimes fallen short of the homodrome- kathodic effect. The first inequality proves nothing, as it might be an effect of ordinary polarisation ; the second inequality proves, that under certain conditions, and in spite of ordinary polarisation, the kathode is the more effective pole. So that, in sum, we may conclude with certainty that both poles are effective, and with less certainty that the kathode PA B C A //•?£. —>• • i Resp. 1 2 FROG'S' SKIN. All responses are outgoing.
