Observe further, that the greater number of volcanic mountains are in the vicinity of the sea. it is thence, they draw the materials that furnish fuel to their fires. These fires are extinguished, or are never kindled, in proportion as they are further from the sea. Their fuel are the gases of which air is composed; that is to say, water and salt. Volcanoes then are springs on a vast scale, whence continually blows a gaseous fluid, incessantly renewed. Part of this gas is inflamed and consumed in the atmosphere. The other part condenses in lavas. The stony matters are instantaneously formed by the contact of air, like a certain gas which changes instantly to quartz by the action of water.
