Before proceeding further with Pro
fesor Cox,s description. it Should be
borne in mind that the corpuscles
which are emitted from radium, be-
come luminous when brought into con
tect with solid bodies under certain
onditions. He says:
could We take our stand on the
moon, we should thus see the earth at

In other Words, the contact of the
rapidly moving stream of corpuscies
with Tie earth should make them
luminous at the edge of the sphere,
past which they shoot into space.
Furthermore as Professor Cox
| points out, the eartn herself helps to
! increase the volume of the lumlnes-
| cence, because as the negative charge
| of the sphere becomes strong enough,
! it repels many of the corpuscles, shoot
! ing them back toward the sun, on the
way toward which they are recaught
| by the rush earthward and drifted
again into the tail.
"The effect" says Professor Co..
will be as if a sheaf of light projected
from the earth toward the sun"
We can see this sheaf of light. AT
least it has been given as an opinion
| tnat the zodiacal light, that mysterious
l
| effulgence of the horizon which has
never been explained is nothing more
than this sheaf of light.
The zodacal light says New
combs popular Astronomy, consists
Of a soft, faint column of light which
| may be seen rising from the western
| ;nl,t al
winter or spring evening
ut may also be seen rising from
the eastern horizon just before day
| break in the summer or autumn.
Is the zodiacal ligh1 merely the
earth's fiery tail made visible to the
inhabitants thereof?
It might well be, for the lumInls-
| cence would he visible only at night
and the peculiar position Of the sheaf
would permit it 10 be viewed by the
people on earth only just after sun
down or Just before sunrise, if al all.
But this is not all Professor New
comb says in his book on astronomy:
another mysterious phenomenon
associated with tie zodiaeal li~ht Is
| the Gegenschein.
1T is said that in that point of the
heavens directly opposite the sun
there is an elliptical patch Of light a
| few degrees in extent Of such extreme
faintness that it can be seen only by
Itne most sensitive eyes, under the best
