A Ruhmkorff device consists of a Bunsen battery operated by means of potassium dichromate, which does not smell; an induction coil puts the electricity generated by the battery in contact with a lantern of a particular design; in this lantern there is a spiral glass tube that contains a vacuum with only a residue of carbon dioxide or nitrogen. When the device is operative, this gas becomes luminous, producing a steady whitish light. The battery and coil are placed into a leather bag that the traveler carries on a shoulder strap. The lantern, carried outside, supplies quite sufficient light even in deep darkness; it allows one to venture into the midst of the most inflammable gases without fear of explosions, and it is not extinguished even in the deepest waters. Mr. Ruhmkorff is a scholar and skilled physicist; his great discovery is the induction coil, which allows one to generate high-tension electricity. In 1864, he won the five-year prize of 50,000 francs reserved by the French government for the most ingenious application of electricity (author’s note).

The descent to Hell is easy (Latin; from Virgil’s
