Theory of the elevation of water within the mountains.
OF THE HEAT THAT IS IN THE WORLD.
Where there is life there is heat, and where vital heat is, there is
movement of vapour. This is proved, inasmuch as we see that the
element of fire by its heat always draws to itself damp vapours and
thick mists as opaque clouds, which it raises from seas as well as
lakes and rivers and damp valleys; and these being drawn by degrees
as far as the cold region, the first portion stops, because heat and
moisture cannot exist with cold and dryness; and where the first
portion stops the rest settle, and thus one portion after another
being added, thick and dark clouds are formed. They are often wafted
about and borne by the winds from one region to another, where by
their density they become so heavy that they fall in thick rain; and
if the heat of the sun is added to the power of the element of fire,
the clouds are drawn up higher still and find a greater degree of
cold, in which they form ice and fall in storms of hail. Now the
same heat which holds up so great a weight of water as is seen to
rain from the clouds, draws them from below upwards, from the foot
of the mountains, and leads and holds them within the summits of the
mountains, and these, finding some fissure, issue continuously and
