The response is always of the nature of an outgoing current at A, and at B for both directions of excitation.

Experiment 11. Cut's Pan: Pads excited and led off as in previous experiment. Excitation " weak " and " strong " through electrodes A and B. Response through A and C arid through B and C. Ingoing response after weak excitation ; outgoing response after strong excita- tion. Berne coil. Four Leclaliche's in primary circuit; tetanisation
