1t Is interesting to note that prob
ABLY 5three- fourth5 of these metals were
discovered within ten years OF the close
|of the eighteenth and ten years after
the beginning of tho nineteenth CEN
tury. About that time there was an
awakening in the chemical world that
led to hundreds Of important discov-
cries IN chemistry. Some OF these dis
|cOvertes We're almost as remarkable az
those made in the astronomical world.
Long before the eye of man ever saw
them. an astronomer figured out that
the planetoIds existed. Another stu
dent OF the heavens forecasted the ap-
pearance, of the great planet Neptune
before mortal man had known that
such a planet was whirling through
space, That electromagnetic that there
was some cause for the agitation OF
the planet Uranus and Its deviation
from Its usual orbit. Taking the
known laws of his science, he figured
out the presence of another planet,
and forecasted when and where it
would become visible. His forecast
worked out to the dot. and stands to-
day as one of the greatest achieve
Fments OF the astronomical world.
Likewise, when the chemist was eX-s
perimenting with the strange, elusive,
and wonderful metals then known, he
found gap between two of them. He
concluded that somewhere In the uni-
verse there was another metal that
would FIJI that gap. Acting on that
conclusion, he proceeded to hunt for it,
land success at last crowned his ef-
forts, showing that. after all, man may
make themselves pretty familiar with
