ABSTRACT
The electric oscillations of open induction coils have a period of vibration that is measured in ten-thousandths of a second. The oscillations which are here dealt with are about a hundred times as rapid as those observed by Feddersen. It is clear in the first place that the natural oscillations of the latter system would be more powerful, and in the second place that the position of the spark in it is more suitable for exciting the vibration. The thread’s conductivity is obviously good enough to allow the current to follow the relatively slow alternations of the discharge from the coil; but in the case of the exceedingly rapid oscillations of the rectilinear circuit it is, not good enough to bring about an equalization of the electrifications. The existence of regular oscillations, however, was only assumed for the purpose of explaining a comparatively small number of phenomena, which might perhaps be accounted for in other ways.
