solderedto it a copper wire 50 cm. or more long. Connect these two wires for a moment with the binding-posts ofthe lecture-table galvanometer (see Fig. 252) to show that the cellin its present condition gives no perceptible current. Leave one of the wires connected to the galvanometer, and… … FIG. 252. Observe the direction of the deflection produced, and note whetherthis deflection increases or diminishes during the next two minutes. Remove the Daniell battery from the circuit and test the lead-cellas at the beginning to see whether it can now produce a perceptibledeflection of the…
