frozen in the air. A frozen piece of water becomes ice. Snow differs from this only, in the water of the ice freezing, when it is of its usual density; and the water of the snow, when its particles are still separate, or reduced to vapour. Experiments have been made, which prove that snow is twenty-four times lighter than water; and that it fills up ten or twelve times more space, at the moment of falling, than the water produced from it when melted; which could not be the case, if the snow was not a water extremely rarified. But snow is not mere water; for the construction of its particles, and the effects it produces, are different from that of water and ice. In this respect, the manner in which the snow forms itself has something very remarkable in

it.

When particles of vapour, collected together, freeze in the atmosphere, the saltpetre, dispersed in the air, comes and unites with it in the form of a little dart of a hexagonal shape. While a great number of such little darts unite together, the particles of water which are among them grow hard, and take the form of the saltpetre. This accounts for the flakes with six sides, which are composed of points like little needles, at each side of which, darts or smaller threads join themselves, though their form frequently alters when carried here and there by the wind. How wonderful the form of these flakes of snow would ap pear to us, if we were not accustomed to see them every year? But, because certain wonders occur often, is that a reason for being inattentive to them? No, far from it: let us be the more care. ful to examine into them, and to admire the pow-, er of God, who, in every season, shows himself so rich, so inexhaustible in means to provide for the conveniencies and pleasures of mortals. Havewe a right to complain that winter does not suppiy variety of amusements for the senses and the

understanding? Is it not an astonishing spectacle, to see that nature has formed even the flakes of snow with the most exact symmetry? to see such a prodigious number of them fall from the sky! to observe the several forms water takes under the creating hand of God? sometimes it forms itself into hail; sometimes it hardens into ice; and sometimes changes into snow, and into innumerable flakes of it. All these changes serve at the same time for the use and embellishment of the earth; and even in the smallest phenomena of nature, God shows himself great, and worthy our adoration. I will no longer look upon snow with indifference. Its form, and the advantages resulting from it, will lead me to thee, O Lord, who made it, and spreadest it upon the earth. To thee, O my God, who lovest thy works, and whom all nature obeys; who causest the snow to fall in flakes like wool; who spreadest the white frost like ashes; who casteth hail as in pieces; who ordereth the cold to bless and fertilize the earth; to Thee be all praise, honour and giory.

The Rapidity with which Human Life passes away.

OUR life is short and transitory. This is an incontestible proposition, though, to judge from the conduct of most people, one would not suppose it a received truth. Let us judge by our own experience: Ought not each step we have taken, from our births to this moment, to have, convinced us of the frailty of life? Let us consider only with what swiftness, the days, the weeks, the months, and the years, have passed, or rather flown away. They were over, even; before we perceived it. Let us endeavour to re cal them to mind, and to follow them in their

rapid flight. Is it possible to give an account of the different æras? If there had not been in our lives certain very remarkable moments, which made impression on our minds, we should be still less able to recollect the histories of them. How

many years of our infancy, devoted to the amusements of youth, which we can say nothing of, but that they have glided away? How many others have passed in the thoughtlessness of youth; during which, misled by our inclinations, and given up to pleasure, we had neither the wish, nor the time, to look into ourselves? To these years succeeded those of a riper age, more capable of reflection. We then thought it was time to change our way of life, and to act like reasonable men; but the business of the world took possession of us to such a degree, that we had no leisure to reflect on our past lives. Our families increased, and our cares and endeavours to provide for them increased in proportion. Insensibly the time draws nigh, in which we arrive at old age; and perhaps, even then, we shall neither have leisure nor force of mind to recollect the past, to reflect upon the period to which we are come, upon what we have done, or neglect. ed to do; in a word, to consider the purposes for which God placed us in this world. In the mean time, what can insure our ever attaining that advanced age? A thousand accidents break the delicate thread of life, before it comes to its full length. The child just born falls, and is reduced to dust. The young man who gives the highest hope, is cut down, in the age of bloom and beauty; a violent illness, an unfortunate accident, lays him in the grave. Dangers and accidents multiply with years: negligence and excess lay the seeds of maladies, and dispose the body to catch those that are epidemical. The last age is still more dangerous. In a word, half of those who are born are carried out of the world, and perish, in

the short space of their first seventeen years. Behold the concise, but faithful history of life! O may we redeem those days, so short and so important, in learning how to number them, and redeem the time which flies so swiftly away! Even while we make these reflections, some moments are flown. What a precious treasure of hours and days should we not lay up, if, from the numberless moments we have to dispose of, we often devoted some of them to so useful a purpose! Let us think of it seriously; every instant is a portion of life impossible to recal, but the remembrance of which may be either the source of joy or sorrow. What heavenly enjoy. ment is it, to be able to look happily on the past, and to say to one's self with truth, "I have lived so many years, during which I have sowed a rich seed of good works; 1 do not wish to begin them again, but I do not regret that they have passed?" We should be able to hold this lan guage, if we fulfilled the end for which life was given us; if we devoted our short space of time to the great interests of eternity.

The Frost sometimes seen on Glass Windows.

THIS little phenomenon shews us what variety, order, and simplicity, there is in the smallest productions of nature. We often admire the extraordinary figures which frost upon the glass presents to us; but it seldom happens that this object is attended to as much as it merits, how ever unimportant it may be in itself. The phenomenon in question has its principle in the fluidity of fire. When it is confined in the warm air of a room, it tries to spread itself on all sides, and to penetrate that part where there is least matter

homogeneal to its own. This is the reason it runs through the close texture of glass, which contains neither air nor heat. In going through glass it leaves at the inside, and near any opening, the particles of air and water to which it was united. It forms itself into a cloud, which thickens in proportion as the fire goes out of it, till there remains too little of it in the room to preserve the fluidity of the thickened particles of the water on the glass. They then congeal; and the saltpetre in the air, mixing with them, produces the variety of figures with which the glass is covered. The beginning, or the sketches of these figures, is formed by very small threads of ice, which insensibly unite, till the whole glass is covered with a coat of ice. These threads are the origin of all the figures; and the first weav ing of these may be distinctly seen. We see at first some lines extremely fine, out of which lines come (nearly in the same manner as we see come out of a quill) some threads, which in their turn bear other branches. When it freezes hard, and the first coat of ice grows thick, it produces the most beautiful flowers and lines of every sort, sometimes strait, sometimes spiral.There is reason to believe that this great variety of figures does not proceed entirely from the motion of the air, and the particles of fire, but in some measure from the little imperceptible chinks there are in glass. Whatever is the cause of the phenomena, it is certain that this sport of nature shews us much art, united with much simplicity.

Perhaps my readers may think trifling all that can be said on an object which has no other value than to please the sight for a short time; but it seems to me, that minute points of this kind have greatly the advantage of those which often fill up our time. With what frivolous matters, what nothings, are we sometimes amused? Would not certain phenomena of nature, which
