ving wheel, top,
or cylinder, to show the effects of increasing rates of vibration. The
illustration supposes a wheel, top, or revolving cylinder, running at a
low rate of speed--we will call this revolving thing "the object" in
following out the illustration. Let us suppose the object moving slowly.
It may be seen readily, but no sound of its movement reaches the ear.
The speed is gradually increased. In a few moments its movement becomes
so rapid that a deep growl or low note may be heard. Then as the rate is
increased the note rises one in the musical scale. Then, the motion
being still further increased, the next highest note is distinguished.
Then, one after another, all the notes of the musical scale appear,
rising higher and higher as the motion is increased. Finally when the
motions have reached a certain rate the final note perceptible to human
ears is reached and the shrill, piercing shriek dies away, and silence
follows. No sound is heard from the revolving object, the rate of motion
being so high that the human ear cannot register the vibrations. Then
comes the perception of rising degrees of Heat. Then after quite a time
the eye catches a glimpse of the object becoming a dull dark reddish
color. As the rate increases, the red becomes brighter. Then as the
speed is increased, the red melts into an orange. Then the orange melts
into a yellow. Then follow, successively, the shades of green, blue,
indigo, and finally violet, as the rate of sped increases. Then the
violet shades away, and all color disappears, the human eye not
being able to register them. But there are invisible rays emanating from
the revolving object, the rays that are used in photographing, and other
subtle rays of light. Then begin to manifest the peculiar rays known as
the "X Rays," etc., as the constitution of the object changes.
Electricity and Magnetism are emitted when the appropriate rate of
vibration is attained.

When the object reaches a certain rate of vibration its molecules
disintegrate, and resolve themselves into the original elements or
atoms. Then the atoms, following the Principle of Vibration, are
separated into the countless corpuscles of which they are composed. And
finally, even the corpuscles disappear and the object may be said to Be
composed of The Ethereal Substance. Science does not dare to follow the
illustration further, but the Hermetists teach that if the vibrations be
continually increased the object would mou
