Hand electrodes. Hand electrodes:—Two stout copper wires are passed through glass tubes for insulation and rigidity. The ends of the latter are sealed with electric cement; the tubes are tied together and their ends are covered with marine glue, the free ends of the wire are shaped conveniently. The other ends are soldered to flexible wires which terminate in tags that will fit either screw-down or perforated Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Birch, De Burgh.
