A, entrance box; B, wire-screen door; D and F, location of card-holders; E,E, electric chambers; G, H, I, way out of box; K, electric key; L, electric battery; M, inductorium. D the chick passed into the electric chamber E, the floor of which was crossed with copper wires i cm. apart, so arranged that they formed an interrupted circuit which could be closed by the chick when the current was on by its stepping simul- taneously on two adjoining wires. Out of E the chick passed through the opening F, cm. wide, the position of the second card. From G there was an outlook through the wire netting.
