tures of the earth issue in springs and sulphur minerals and
volcanoes, as at Mount Etna in Sicily and in many other places.

The ancients called man the world in miniature, and certainly the name
is a happy one, because man being composed of earth, water, air and
fire, the body of the earth resembles the body of man. As man has in
him bones for the support and framework of his flesh, likewise in the
world the rocks are the supports of the earth; as man has in him a pool
of blood in which the lungs rise and fall in their breathing, so the
body of the earth has its ocean which rises and falls every six hours
as if the world breathed; as from the aforesaid pool of blood veins
issue which {164} ramify throughout the human body, so does the ocean
fill the body of the earth with innumerable veins of water. The body
of the earth lacks sinews, which do not exist because sinews are made
for movement, and the world being in perpetual stability no movement
occurs, and there being no movement, sinews are not necessary; but in
all other points they resemble each other greatly.

Water is the driver of nature.

54.

In explaining the action of water remember to cite experience first and
then reason.

Do not forget that you must put forward propositions adducing the
above-mentioned facts as illustrations, not as propositions,--that
would be too simple.

Water in itself has no stability and cannot move of its own accord,
save to descend. Water of its own accord does not cease to move unless
it is shut in.

The body of the earth, like the body of animals, is intersected with
ramifying veins, which are all {165} united and constructed for the
nourishment and life of the earth and of its creatures.

[Sidenote: Water is the Blood of the World]

The water which rises in the mountains is the blood which keeps the
mountain alive, and through this conduit or vein, nature, the helper of
her creatures, prompt in the desire to repair the loss of the moisture
expended, proffers the desired aid abundantly; just as in a stricken
spot in man you will see, owing to the aid which is brought, the blood
abound under the skin in a swelling, so as to succour the spot which
has been stricken; likewise, in the case of the vine, when it is cut at
its extremity, nature causes its moisture to rise from the lowest root
to the end of the extremity
