Invisible Clouds.

In the recent English tests of lighthouse illuminants was brought out the curious fact—of great practical as well as scientific interest - that remarkable changes in the transparency of the air occur without any visible haze or mist. Invisible clouds seemed to float by, obscuring the lights for a time; and it sometimes happened that while the distant French lights showed with unabated brilliancy, the experimental lights, only a mile and a quarter away, had lost one-fourth to one-third their power. Japan, according to the new census, has a population of 38,500,000, or about the same as that of the United States in 1870. In area Japan is about five times the size of Pennsylvania. He who strives after a long and pleasant form of life must seek to attain continued equanimity.
