Distribution of Land and Water.—Our conception oithe relative distribution of land and water over the surface ofthe Earth has been hitherto limited to a comparison of thesuperficial areas occupied by these two elements, such as theyare presented to us on a chart of the world. In this sense wespeak of the different continents and islands which constitutethe sum total of dry land, and of the different oceans and seaswhich compose the water-surface of our planet. But if wewish to form a more perfect idea of the distribution of land andwater, we must consider not only the length and breadth of theareas occupied, but also the height of the land and the depthof the water; in other words, the volume of those portions ofthe solid crus
