The only articles we get from the moon, are moonlight and
madness. _Lunar_ caustic is not derived from the planet alluded to.
Of the stars, one of the most brilliant is _Sirius_, or _the Dog-star_,
which it is calculated gives just one-twenty-millionth part of the light of
the sun, or about as much as that of a farthing rushlight. It would seem
that such a shabby degree of brilliancy was hardly worth having; but when
it is remembered that it takes three years to come, it really seems hardly
worth while to travel so far to so very little purpose.
The most magnificent of the starry phenomena, is the Milky Way or _Whey_;
and, indeed, the epithet seems superfluous, for all _whey_ is to a certain
extent milky. The _Band of Orion_ is familiar to all of us by name; but it
is not a musical band, as most people are inclined to think it is. Perhaps
the allusion to the _music of the spheres_ may have led to this popular
error, as well as to that which regards Orion's _band_ as one of _wind_
instruments.
We shall not go into those ingenious calculations that some astronomers
have indulged in, as to the time it would take for a cannon-ball to come
from the sun to the earth, for we really hope the earth will never be
troubled by so unwelcome a visitor.
