_Chemistry of Suns revealed by Light._

When we examine the assemblage of colors spread from the white ray
of sunlight, we do not find red simple red, yellow yellow, etc.,
but there is a vast number of fine microscopic lines of various
lengths, parallel--here near together, there far apart, always the
same number and the same relative distance, when the same light
and prism are used. What new alphabets to new realms of knowledge
are these! Remember, that what we call colors are only various
numbers of vibrations of ether. Remember, that every little group in
the infinite variety of these vibrations may be affected differently
from every other group. One number of these is bent by the prism
to where we see what we call the violet, another number to the
place we call red. All of the vibrations are destroyed when they
strike a surface we call black. A part of them are destroyed when
[Page 29] they strike a substance we call colored. The rest are
reflected, and give the impression of color. In one place on the
flag of our nation all vibrations are destroyed except the red; in
another, all but the blue. Perhaps on that other gorgeous flag, not
of our country but of our sun, the flag we call the solar spectrum,
all vibrations are destroyed where these dark lines appear. Perhaps
this effect is not produced by the surface upon which the rays fall,
but by some specific substance in the sun. This is just the truth.
Light passing through vapor of sodium has the vibrations that would
fall on two narrow lines in the yellow utterly destroyed, leaving
two black spaces. Light passing through vapor of burning iron has
some four hundred numbers or kinds of vibrations destroyed, leaving
