"When we have once the true value of the sea water and its basin, we can logically conclude from this the value of the dry land. But here is the place to remark that the highest chains are placed always only upon the greatest protuberances or vaults of the earth's surface, which is quite natural; but together give an indica- tion of the maxima and minima values of the elevations upon the whole globe, as well as in each country. In other words, if we find heights from 24,000 to 27,000 feet in South America and the Himalaya, or similar cavities in the Austral seas, we must not believe that there exist in the earth such a force of elevation or subsidence ; but that only the last elevations have taken place upon a soil already elevated upon a vault of the earth, and that in the same way the subsidence has happened on parts already subsided. It is yet possible that a chain may be wholly upheaven in later times ; but our Alps in Europe shew us that we can hardly admit of a single elevation of 8000 feet at once, for all the summits and pinnacles which reach above 10,000 feet did gain this height only by the inclination of their composing beds. On the other hand, a yet unknown physical law has established an intimate relation between the value of the greatest eleva- tions or upheavings, or highest mountains of each continent and their relative individual extent.
