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.
