impulse of these considerations, that I have, with some hesitation, prevailed upon myself to attempt an argument which I think fitted to soften and subdue those prejudices which lie at the bottom of what may be called the infidelity of natural science; if possible to bring over to the humility of the Gospel, those who expatiate with delight on the wonders and the sublimities of creation; and to convince them that a loftier wisdom still than that even of their high and honourable acquirements, is the wisdom of him who is resolved to know nothing but Jesus Christ and him crucified.

It is truly a most Christian exercise, to extract a sentiment of piety from the works and the appearances of nature, It has the authority of the Sacred Writers upon its side, and even our Saviour himself gives it the weight and the solemnity of his example. "Behold the lilies of the field; they toil not, neither do they spin, yet your heavenly Father careth for them." He expatiates on the beauty of a single flower, and draws from it the delightful argument of confidence in God. He gives us to see that

taste may be combined with piety, and that the same heart may be occupied with all that is serious in the contemplations of religion, and be at the same time alive to the charms and the loveliness of nature.

The Psalmist takes a still loftier flight. He leaves the world, and lifts his imagination to that mighty expanse which spreads above it and around it. He wings his way through space, and wanders in thought over its immeasurable regions. Instead of a dark and unpeopled solitude, he sees it crowded with splendour, and filled with the energy of the Divine presence. Creation rises in its immensity before him, and the world, with all which it inherits, shrinks into littleness at a contemplation so vast and so overpowering. He wonders that he is not overlooked amid the grandeur and the variety which are on every side of him, and passing upward from the majesty of nature to the majesty of nature's Architect, he exclaims, "What is man that thou art mindful of him, or the son of man that thou shouldest deign to visit him?"

It is not for us to say, whether inspiration revealed to the Psalmist the wonders of the modern astronomy. But even though the mind be a perfect stranger to the science of these enlightened times, the heavens present a great and an elevating spectacle, an immense concave reposing upon the circular boundary of the world, and the innumerable lights which are suspended from on high, moving with solemn regularity along its surface. It seems to have been at night that the piety of the Psalmist was awakened by this contemplation, when the moon and the stars were visible; and not when the sun had risen in his strength, and thrown a splendour around him, which bore down and eclipsed all the lesser glories of the firmament. And there is much in the scenery of a nocturnal sky, to lift the soul to pious contemplation. That moon, and these stars, what are they? They are detached from the world, and they lift you above it. You feel withdrawn from the earth, and rise in lofty abstraction above this little theatre of human passions and human anxieties. The mind abandons itself to reverie, and is transferred in the ecstacy of its thoughts, to distant and

unexplored regions. It sees nature in the simplicity of her great elements, and it sees the God of nature invested with the high attributes of wisdom and majesty.

But what can these lights be? The curiosity of the human mind is insatiable, and the mechanism of these wonderful heavens, has, in all ages, been its subject and its employment. It has been reserved for these latter times, to resolve this great and interesting question. The sublimest powers of philosophy have been called to the exercise, and astronomy may now be looked upon as the most certain and best established of the sciences.

We all know that every visible object appears less in magnitude as it recedes from the eye. The lofty vessel, as it retires from the coast, shrinks into littleness, and at last appears in the form of a small speck on the verge of the horizon. The eagle with its expanded wings, is a noble object; but when it takes its flight into the upper regions of the air, it becomes less to the eye, and is seen like a dark spot upon the

vault of heaven. The same is true of all magnitude. The heavenly bodies appear small to the eye of an inhabitant of this earth, only from the immensity of their distance. When we talk of hundreds of millions of miles, it is not to be listened to as incredible. For remember that we are talking of those bodies which are scattered over the immensity of space, and that space knows no termination. The conception is great and difficult, but the truth is unquestionable. By a process of measurement which it is unnecessary at present to explain, we have ascertained first the distance, and then the magnitude of some of those bodies which roll in the firmament; that the sun which presents itself to the eye under so diminutive a form, is really a globe, exceeding, by many thousands of times, the dimensions of the earth which we inhabit; that the moon itself has the magnitude of a world; and that even a few of those stars, which appear like so many lucid points to the unassisted eye of the observer, expand into large circles upon the application of the telescope, and are some of them much larger than the ball which we
