Oliver Lodge,

Experimental and Theoretical Physics Studies

I Do not know how far the description of little isolated experiments is serviceable, but I am tempted to communicate a simple plan I use for exciting electric oscillations in dumb-bells, ellipsoids, elliptical plates, spheres, or other conducting bodies of definite geometrical shape unhampered by a bisecting sparkgap. I do it by supplying electricity to opposite ends of the conductor by means of Leyden jar knobs brought near enough to spark to it: said knobs being likewise connected with the terminals of a small Ruhmkorff coil. The charge thus supplied or withdrawn at every spark settles down in the conductor after a few oscillations, and these excite radiation in surrounding space.
