THE
foundation
of
all
those
fluids
that
are
to
be
taken
into
consideration
for
our
purpose
is
formed
by
one
of
the
most
universal
elements
on
our
globe
the
water.
It
is
a
conditio
sine
qua
non
both
for
building
up
and
preserving
the
whole
organic
world.
A
cell,
the
most
primitive
of
all
living
beings,
e.
g.,
a
bathybius,
as
well
as
the
most
highly
developed
ones,
as
we
see
them
in
the
higher
organisms
of
the
vegetable
and
animal
king-
doms,
contains
water
as
a
fundamental
basis.
Although
there
are
cells,
and
groups
of
them,
that
may
retain
vitality for
thousands
of
years,
even
when
in
dried-up
condition,
yet
this
does
not
affect
the
relatively
higher
developed
beings
in
the
least.
"
Corpora
non
aguntnisi
fluida
"
is
an
old
chemical
rule,
and,
indeed,
stoppage
of
all
functions,
or
even
death,
would
occur
as
soon
as
the
necessary
water
should
not
be
supplied.
Water
is
indispensable
for
fulfilling
the
physical
and
chemical
processes,
among
which
ranks
highest
the
process
of
diffusion,
or
the
Endosmosis
and
Exosmosis.
We
feel
the
lack
of
water
involuntarily,
and
call
this
feeling
"
thirst."
The
inclination
of
satisfying
this
feel-
ing
by
drinking
water,
or
water-containing
liquids,
is
forced
upon
us
by
nature.
Thus,
thirst
compels
us
to
drink,
and
is,
therefore,
one
of
these
