The man in narrow circumstances, or prest severely with many cares may
be purified by such pressure like the water described in this extract:
The best water is that which has gone deepest in the earth,
where there is the tightest pressure, atmospheric and telluric.
Continued and intensified filtration has refined it; but it is
here, and not in its open-air exposure, before or after, that
the water gets effective oxidation. The remarkable fact that
water absorbs oxygen in something like a geometrical ratio
to the increase of pressure, coupled with the other equally
important fact that under a certain pressure and temperature
organic germs cease to exist; both these conditions, protracted
for the water by a long detention in the depths of the earth,
secure the rarest refinement and also vitalization of the
element.--_The Sanitary Era._
