Abstract:
"The
abrupt
termination
of
solar
and
stellar
spectrum
below
A 2900
has
been
a
great
handicap
to
the
advancement
of
our
knowledge
of
the
heavenly
bodies
; because
the
information
gained
from
the
study
of
the
spectrum
beyond
A,
2900
is
not
sufficient
'to
explain
the
problems
of
stellar
mechanisms
operative
there."
