"A celestial body is said to be
eclipsed when it is immersed in the
shadow of another. Thus a 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 if 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 INSULT
Gent to cause injury from its use.
Micro organisms are present in the
air, the water and the earth. They
are not only on the earth, but the
upper layers of terrestrial crust are
teeming with them. They are carried
by the atmosphere as dust, and de-
posted upon the surface of all objects.
They exist in vast numbers upon and
| in the human body They are present
with the body in life, and do not leave
it in death until it is resolved into the
elements Hence there can be no doubt
| but they are an important factor in
nature.
! "A mining expert sent to investi-
gate some Arizona properties for Den
yer capitalists reports the finding of a
most remarkable bridge formed by
tree of agatized wood, spanning a
canyon forty-fve 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. The silt in time became
! sandstone, and the wood gradually
passed through the stages of minerali-
cation, until it is now a 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 hint-lilte sub
stance of the agatized wood having
resisted the erosion OF the watertlow.
