The dis- charge-tubes, which were in general either rectangular tubes or spher- ical bulbs, where placed close to the turns of C. When the difference of potential between A and B is sufficiently large, a spark i)asses across the air-break, and the electrical oscillations set up produce a large electromotive force in the neighborhood of the coil, sufficient under t^ivorable circumstances to cause a bright discharge to pass through the vacuum-tubes. In some experiments tlie jars, at the suggestion of Prof. Oliver Lodge, were connected up differently, and are represented. (WimJiurst) earth earlli.
