IA celestial body is said to be
eclipsed when it is immersed in the
shadow of another. Thus lunar
eclipse is caused by the moon entering
the shadow of the earth. Jupiter's sat-
elites are frequently eclipsed by pass
ing through the shadow cast by their
primary. A solar eclipse is due to the
interposition of the moon between the
sun and earth, and the phenomenon is
strictly an occultation, but the former
term is retained for convenience.
The Massachusetts State Board Of
Health concludes, from Investigations
OF artificial ice, that artificial processes
OF freezing concentrate the impurities
of the water in the inner core of the
portion last frozen; that the impurities
are least II distilled water is used; that
the number Of bacteria in artificial Ice
Is insignificant under the prevailing
methods Of manufacture, and that the
amount of zinc found in ice is insuifi-
cient to cause injury from its use.
Micro organisms are present in the

are not only on the earth, but the
upper layers Of terrestrial crust are
teeming with them. They are carried

They exist in vast numbers upon and

it in death until 1t is resolved into the

nature.
"A mining expert sent to investi-
gate some Arizona properties for Dem
yer capitalists reports the finding Of o
most remarkable bridge formed by
tree Of agatized wood, spanning
canyon forty-five feet in width. The
tree had at some remote time fallen
and become embedded in the silt of
some great inland sea or mighty water
overflow. Tho silt in time became
sandstone, and the wood gradually
passed through the stages. of minerali-
cation, until it is now wonderful tree
Of solid agate. In after years, water
washed and ate away the sandstone
until canyon forty-fve feet in width
has been formed, the flint-like SUBJ
stance of the agatized wood having
resisted the erosion of the waterfowl.
