"All are but parts of one stupendous whole,

Whose body Nature is, and God the soul."

The atmosphere, supposed to extend sixty miles in height, surrounds the earth like an invisible ocean, and gives to it almost entirely its life-material. In fact, the atmosphere is the great reservoir of the vital elements, from which is derived the principal part, if not all, the material, solid or liquid, which enters into the composition of both plant and animal, whether it be a blade of grass, a leaf, or a tree; an insect, a fish, or a man. It is true, however, that animal-life is more directly the outgrowth of plant-life; and yet the vital forces of both are derived from the air, and return to the air by solar agencies. It is quite certain that all matter, as seen embodied in various forms, consists entirely of certain gases condensed or solidified by chemical laws. The atmosphere itself, and probably infinite space, are filled with matter in the gaseous form, or in some unknown form, destined to be condensed, dissolved, and recondensed in a series of changes as continuous as the infinite ages.

In this sense, not only the earth, but every other planet, contains within itself the seeds of its own dissolution. Yet matter, whatever its form, is still indestructible, and will forever retain its vital forces. It would seem that life is the soul of matter, and that electricity is the soul of life,—immaterial, it may be, and if so, then immortal. Where the material ends, or where the spiritual begins, it is impossible to say. We know that we are endowed with the five senses at birth. We also know that they are the media through which we receive all the impressions and perceptions of our environment; it is from their report that we learn what is agreeable or disagreeable to our physical needs. We choose the agreeable, and reject the disagreeable. Here reason begins, and pronounces judgment. Memory records facts and conclusions. The physical and the mental grow in strength from infancy to manhood; they are a living unit. The one is real, and the other ideal. Of spirit or soul we know nothing, nor can we prove their existence, unless we accept the proofs as furnished by revelation. It is certain, however, that our moral character survives us and continues to have an influence in the world for good or for evil "according to the deeds done in the body." This fact is something which we can comprehend as constituting the ideal of our spiritual existence. Nor need we doubt that in discharging our duties to our fellow-men, we discharge our duties to God.

Everywhere about us, and especially in atmospheric phenomena, we see an epitome of Nature's processes and marvellous formative power. Not a snowflake falls to the ground that does not bring with it a crystallization of the most beautiful specimens of artistic embroidery, far excelling the finest needle-work ever wrought by woman's hand. The same is true of the silver frostwork traced on the window-pane by the delicate touch of invisible fingers. In truth, every gem that glitters in the mine, every flower of the field, and every star in the sky, is but a crystallized expression of the beautiful, blended with a silent love that is pure and heartfelt, as if akin to us. In reality they are our kindred, and we are their kindred.

Nature seems to delight in creating the wonderful as well as the beautiful, and often combines both in the same exhibition. Hence she entertains us occasionally with a magnificent display of fireworks, known as Northern Lights; or with an apparent shower of falling stars; or with the sudden descent of an aërolite, all ablaze, as if dropped from the fiery forge of the sun; or with a brilliant comet, which with its long and glittering trail sweeps in ladylike style the star-dust from the pavement of the sky. These singular occurrences, though sometimes regarded as ominous, are but a part of Nature's systematic operations. They cannot with any foundation in truth be attributed to accident; for it is impossible that accidents should happen in the workshops of Nature, or in the administration of her government.

How the various meteors are actually formed, or whence they come, is a mystery which has induced much speculation among scientific men. Some say they are volcanic fragments thrown from the moon, or from some distant planet, or perhaps from a crater of the sun; while others, with more reason, suppose that they are generated in space, or in the earth's atmosphere, and are nothing more than condensed gases which constitute the elements of solid matter, and which become in some instances so hardened by chemical action as to assume the solidity of stone or iron.

And hence it often happens that the latter class of these erratic strangers fall from the sky to the earth with a terrific explosion. In ancient times their appearance was regarded as portentous of national or individual calamities. The Chinese have records of meteoric showers, and the fall of aërolites, which occurred more than six hundred and forty years before the Christian era. The Greeks and Romans observed and recorded similar phenomena. Between the years 903 and 1833, not less than nineteen periodical star-showers have been recorded. The regular period of their occurrence is once in every thirty-three years, or thereabout, and usually about the middle of November. But what are called sporadic meteors, or shooting-stars, are of frequent occurrence, and may be seen almost every evening in the year.

The most brilliant meteoric shower on record is that of 1833, when meteors fell at the rate of two hundred and forty thousand per hour, creating the impression that all the stars of heaven had been unsphered, and were falling like a sheet of fire to the earth, and threatening a universal conflagration. Occurring as it did at midnight, and continuing for two or more hours, thousands of people, who witnessed the scene with fear and trembling, supposed the day of judgment had come. In just thirty-three years after this, Nov. 14, 1866, occurred another periodical shower of a similar character, which, though less brilliant, was seen on a more extended scale in Europe than in the United States. Why this apparent storm of fire should occur every thirty-three years, is a mystery which science has not yet been able to explain. It may be a part of the machinery of our planetary system, and is perhaps as regular in its revolutions as the planets; or it may be a method of dissipating an over-accumulation in the earth's atmosphere, or in infinite space, of inflammable gaseous matter, which thus ignites spontaneously, and presents to the eye the appearance of burning sparks flying off, as it were, from the broad anvil and ponderous sledge employed in the great workshop of Nature. Be this as it may, meteoric showers, so far as known, have always proved harmless in their results.

But the aërolite assumes a more formidable character. In outline it is a globular mass heated to intensity, and in its approach comes with a hissing sound, and usually explodes in the atmosphere or when it strikes the earth. Its fragments show that it is a solid body, composed mostly of a ferruginous material. The illumination it creates in its passage through the atmosphere is sometimes seen at the distance of five or six hundred miles. Erratic masses of this kind have been known to fall in all ages and in all countries, and are of frequent occurrence.
