Note: Pure water consists of hydrogen and oxygen, H2O, and
is a colorless, odorless, tasteless, transparent
liquid, which is very slightly compressible. At its
maximum density, 39[deg] Fahr. or 4[deg] C., it is the
standard for specific gravities, one cubic centimeter
weighing one gram. It freezes at 32[deg] Fahr. or
0[deg] C. and boils at 212[deg] Fahr. or 100[deg] C.
(see Ice, Steam). It is the most important natural
solvent, and is frequently impregnated with foreign
matter which is mostly removed by distillation; hence,
rain water is nearly pure. It is an important
ingredient in the tissue of animals and plants, the
human body containing about two thirds its weight of

Inch of water, a unit of measure of quantity of water,
being the quantity which will flow through an orifice one
inch square, or a circular orifice one inch in diameter,
in a vertical surface, under a stated constant head; also
called miner's inch, and water inch. The shape of the
orifice and the head vary in different localities. In the
Western United States, for hydraulic mining, the standard
aperture is square and the head from 4 to 9 inches above
its center. In Europe, for experimental hydraulics, the
orifice is usually round and the head from 1/2 of an inch
to 1 inch above its top.
Mineral water, waters which are so impregnated with foreign
ingredients, such as gaseous, sulphureous, and saline
substances, as to give them medicinal properties, or a
particular flavor or temperature.

Water of crystallization (Chem.), the water combined with
many salts in their crystalline form. This water is
loosely, but, nevertheless, chemically, combined, for it
is held in fixed and definite amount for each substance
containing it. Thus, while pure copper sulphate, CuSO4,
is a white amorphous substance, blue vitriol, the
crystallized form, CuSO4.5H2O, contains five molecules
of water of crystallization.
Water on the brain (Med.), hydrocephalus.
