a. Apparatus for decomposing water and collecting the gases separately. b b. Wires proceeding from the machine at m, n. q, works on the single break, h.
Second Experiment.
The electric light obtained by the passage of the electricity from the battery through the charcoal points, is also an effect that can be produced by magneto-electric machines, the wires leading from the points a b being insulated by glass handles, and placed in the holes m n. (Fig. 237.)

Third Experiment.
The scintillation of iron wire is one of the most pleasing experiments with this apparatus, and is performed by pressing gently one end of a piece of thin iron wire (attached by means of a binding-screw to the upright bar a) against the armature, d. (Fig. 238.)
