Perhaps this matter may be best explained by means of illustrations of the operation of electricity and light—electric vibrations and light vibrations. In both cases the secret of the transmission of the vibrations or waves of vibratory energy may be summed up in the word "transformation." For instance: When we transmit electric vibrations over a fine wire or thread of carbon, the electric vibrations are transformed into light vibrations and manifest as "electric light." In another form of transmission the electric vibrations are transformed into "electric heat." But this is merely one phase of the transformation; consider carefully the more complex phases, as follows: We speak into the receiver of a telephone and the sound vibrations produced by our voice are transformed into electrical vibrations and in that form travel over the telephone wire; arriving at the other end of the wire, these electric vibrations enter into the receiver, and are there transformed into sound vibrations, and as such are heard by the person holding the receiver. Now note this: the sound vibrations do not travel at all; instead, they are transformed into electric waves, which in turn are transformed at the receiving end of the line into sound vibrations once more. And unless the receiving apparatus be present, and properly adjusted, there is no second transformation at all; and in such case the electric vibrations remain such.
