In connection with thoughts of a similar nature, it appeared to me of great interest to demonstrate the rigidity of a vibrating gaseous column. Although with such low frequencies as, say 10,000 per second, which I was able to obtain without difficulty from a specially constructed alternator, the task looked discouraging at first, I made a series of experiments.
When with low frequencies and insignificant potentials indications of that property may be noted, how must a gaseous medium behave under the influence of enormous electrostatic stresses which may be active in the interstellar space, and which may alternate with inconceivable rapidity?
It returned four different frequencies with a relative-intensity pattern which said that they'd been reflected by bronze probably silicon bronze. The polarized beams came back depolarized, of course, but with phase-changes which said the reflector had a rounded, regular form. There was a smooth hull of silicon bronze out yonder. There was other data.
Rovol then threw a switch, and a hemisphere of flaming golden radiance surrounded the laboratory and extended for miles upon all sides. "I get most of the stuff you've pulled so far, but why such a light?" asked Seaton. "As a warning. This entire area will be filled with dangerous frequencies, and that light is a warning for all uninsulated persons to give our theater of operations a wide berth."
The receiving battery has a core pole of katultron and an outer shell of metultron. The receiving battery, of course, picks up all frequencies, the undesired ones being tuned out in detection. Tuning, however, is only a convenience for privacy and elimination of interference in ultrophonic communication.
In trying the preceding experiment with the electric radiometer the potential should not exceed a certain limit, as then the electrostatic attraction between the vanes and the glass of the bulb may be so great as to stop the rotation. A most curious feature of alternate currents of high frequencies and potentials is that they enable us to perform many experiments by the use of one wire only.
High frequency currents, or electric oscillations as they are called, are currents of electricity that surge to and fro in a circuit a million times, more or less, per second. Currents of such high frequencies will oscillate, that is, surge to and fro, in an open circuit, such as an aerial wire system, as well as in a closed circuit.

Incidentally we gain, by the use of very high frequencies, many advantages, such as a higher economy in the light production, the possibility of working with one lead, the possibility of doing away with the leading-in wire, etc. The question is, how far can we go with frequencies?
We call it instinct, a name which is made to cover all other senses in the lower animals, of which we have no cognisance ourselves. Let us take our own senses as a guide: we find that they are all based on the appreciation of frequencies, of greater or less rapidity, by means of organs specially adapted to vibrate in sympathy with those pulsations, and thus we gain knowledge of external things.
