In imaginative literature the greatest writer of the latest period is Heinrich Heine, whose lyrics have attracted general attention. The novel has acquired the same important place in Germany as in England. Among the chief novelists are Freytag, the Countess Ida Hahn-Hahn, Paul Heyse, Spielhagen and Reuter. * * * * * EVERYTHING that regards statesmanship and the interest of the world is in all outward respects of the greatest importance; it creates and destroys in a moment the happiness, even the very existence, of thousands, but when the wave of the moment has rushed past, and the storm has abated, its influence is lost, and even frequently disappears without leaving a trace behind. Many other things that are noiselessly influencing the thoughts and feelings often make far deeper and more lasting impressions on us. Man can for the most part keep himself very independent of all that does not trench on his private life—a very wise arrangement of Providence, since it gives a much greater security to human happiness.—_William von Humboldt._ PHYSICAL SCIENCE. II.—THE CIRCULATION OF WATER ON THE LAND. Although air is continually evaporating water from the surface of the earth, and continually restoring it again by condensation, yet, on the whole and in the course of years, there seems to be no sensible gain or loss of water in our seas, lakes, and rivers; so that the two processes of evaporation and condensation balance each other. It is evident, however, that the moisture precipitated at any moment from the air is not at once evaporated again. The disappearance of the water is due in part to evaporation, but only in part. A great deal of it goes out of sight in other ways. The rain which falls upon the sea is the largest part of the whole rainfall of the globe, because the surface of the sea is about three times greater than that of the land. All this rain gradually mingles with the salt water, and can then be no longer recognized. It thus helps to make up for the loss which the sea is always suffering by evaporation. For the sea is the great evaporating surface whence most of the vapor of the atmosphere is derived.
