CHEMISTRY OF THE STARS
quarter of an ounce of cæsium chloride could be collected.
A splendid tribute this, not only to the sensitiveness of
the spectroscopic method, but also to the confidence and
patience of the searchers.
Among the many problems raised by the spectroscope
is that concerning the peculiar light of the Aurora Borealis.
Its spectrum is characterised specially by a bright yellowish-
green line, which has given rise to much discussion, and
which for long could not be referred to any known element.
Again the discoveries of chemists have supplied the clue,
and it appears that krypton, one of the recently detected
gases of the atmosphere, is the responsible party.
