Our Atmosphere.
Our atmosphere is composed of air (a mixture of seventy-seven parts by weight of nitrogen and twenty-one parts of oxygen), with variable proportions of carbonic acid, aqueous vapors and ammonia, the latter in exceedingly small quantities. How it came here and whence its origin no man can venture to say. It is known that the suns and the planets have atmospheres, but at present little is known concerning the component parts of the atmospheres of those far off globes. The spectroscope is, however, beginning to reveal something of their true character. It is generally conceded that the moon lias no atmosphere, the theory being that the scorial and volcaiu'c lavas absorbed the air and water of that planet millions of years ago.—St. Louis Republic.
