s which throw the guess of Archelaus into
discredit. If our place in the material universe is thus made to
appear very subordinate, we may remember, as M. Arago observes, that
man owes the knowledge of it entirely to his own resources, and
thereby has raised himself to the most eminent rank in the world of
ideas. Indeed, astronomical investigations might not improperly excuse
a little vanity on our part.'
Among the stars, Sirius is the brightest; but twenty thousand millions
of such stars would be required to transmit to the earth a light equal
to that of the sun. And if it were difficult to ascertain the nature
and quality of the sun, it would appear to be still more so to
determine these points with regard to the stars; for the reason, that
the rays, coming from all parts of their disk, at once are
intermingled, and of necessity produce white. This difficulty did not
exist in similar investigations on the sun, because its disk is so
large, that the rays from any one part of it may be examined while the
others are excluded. Under these circumstances, further proof might
seem to be hopeless; but advantage was taken of the fact, that there
are certain stars which are sometimes light, sometimes dark, either
from having a movement of rotation on their own axis, or because they
are occasionally eclipsed by a non-luminous satellite revolving around
them. It is clear, that while the light is waxing or waning, it comes
from a part only of the star's disk; consequently, the neutralisation
of rays, which takes place when they depart from the whole surface at
once, cannot then occur; and from the observations on the portion of
light thus transmitted, and which is found to remain white under all
its phases, we are entitled to conclude, in M. Arago's words, that
'our sun is a star, and that its physical constitution is identical
with that of the millions of stars strewn in the firmament.'
BARBARA'S SEA-SIDE EXCURSION.
It certainly appeared a most improbable circumstance, that any event
should occur worthy of being recorded, to vary the even tenor of life
which Mr and Mrs Norman enjoyed in the holy state of matrimony. They
were young folks--they had married from affection--and, moreover,
their union had been a strictly prudent one; for their income was more
than sufficient for all their unaspiring wants and tastes; and it was
also a 'certainty,' a great good in these days of speculation and
going ahead. Charles Norman
