It is the property of water that it constitutes the vital human of
this arid earth; and the cause which moves it through its ramified
veins, against the natural course of heavy matters, is the same
property which moves the humours in every species of animal body.
But that which crowns our wonder in contemplating it is, that it
rises from the utmost depths of the sea to the highest tops of the
mountains, and flowing from the opened veins returns to the low
seas; then once more, and with extreme swiftness, it mounts again
and returns by the same descent, thus rising from the inside to the
outside, and going round from the lowest to the highest, from whence
it rushes down in a natural course. Thus by these two movements
combined in a constant circulation, it travels through the veins of
the earth.
