American writer Samuel Clemens, aka Mark Twain, is pictured here in Nikola Tesla’s laboratory experimenting with lamps lighted by electric currents passed through his own body. Mr. Clemens holds a loop of bare wire in his hands. Currents are induced in the loop by means of a resonating coil over which the loop is held. These currents traverse the body of the Mr. Clemens, and at the same time, as they pass between his bare hands, they bring two or three lamps held there to bright incandescence. Although the currents experimented with are of a voltage in the hundreds of thousands, they do not distress the experimenter in the slightest. The extremely high tension of the currents which Mr. Clemens is seen receiving prevents them from doing any harm to him.
