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.
