Molecular \Mo*lec"u*lar\, a. [Cf. F. mol['e]culare. See
{Molecule}.] (Phys. & Chem.)
Pertaining to, connected with, produced by, or consisting of,
molecules; as, molecular forces; molecular groups of atoms,
etc.
[1913 Webster]
{Molecular attraction} (Phys.), attraction acting between the
molecules of bodies, and at insensible distances.
{Molecular weight} (Chem.), the weight of a molecule of any
gas or vapor as compared with the hydrogen atom having
weight of 1 as a standard; the sum of the atomic weights
of the constituents of a molecule; thus, the molecular
weight of water ({H2O}) is 18. For more precise
measurements, the weight of the carbon isotope carbon-12
is used as the standard, that isotope having the value of
12.000. In this systen, now used almost universally, the
hydrogen atom has a weight of 1.0079.

5. (Typog.)

mahogany, or boxwood. In the cut, a is the body; b, the
face, or part from which the impression is taken; c,
the shoulder, or top of the body; d, the nick
(sometimes two or more are made), designed to assist
the compositor in distinguishing the bottom of the face
from t`e top; e, the groove made in the process of
finishing, -- each type as cast having attached to the
bottom of the body a jet, or small piece of metal
(formed by the surplus metal poured into the mold),
which, when broken off, leaves a roughness that
requires to be removed. The fine lines at the top and
bottom of a letter are technically called ceriphs, and
when part of the face projects over the body, as in the
letter f, the projection is called a kern.

[1913 Webster] The foregoing account is conformed to
the designations made use of by American type founders,
but is substantially correct for England. Agate,
however, is called ruby, in England, where, also, a
size intermediate between nonpareil and minion is
employed, called emerald.
[1913 Webster]
{Point system of type bodies} (Type Founding), a system
adopted by the type founders of the United States by which
the various sizes of type have been so modified and
changed that each size bears an exact proportional
relation to every other size. The system is a modification
of a French system, and is based on the pica body. This
pica body is divided into twelfths, which are termed
"points," and every type body consist of a given number of
these points. Many of the type founders indicate the new
sizes of type by the number of points, and the old names
are gradually being done away with. By the point system
type founders cast type of a uniform size and height,
whereas formerly fonts of pica or other type made by
different founders would often vary slightly so that they
could not be used together. There are no type in actual
use corresponding to the smaller theoretical sizes of the
point system. In some cases, as in that of ruby, the term
used designates a different size from that heretofore so
called.

wazzar, Icel. vatn, Sw. vatten, Dan. vand, Goth. wat[=o], O.
Slav. & Russ. voda, Gr. 'y`dwr, Skr. udan water, ud to wet,

which forms rivers, lakes, seas, etc. "We will drink

[1913 Webster]
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
water.
[1913 Webster]
2. A body of water, standing or flowing; a lake, river, or
other collection of water.

4. (Pharm.) A solution in water of a gaseous or readily
volatile substance; as, ammonia water. --U. S. Pharm.
[1913 Webster]
5. The limpidity and luster of a precious stone, especially a
diamond; as, a diamond of the first water, that is,
perfectly pure and transparent. Hence, of the first water,
that is, of the first excellence.

6. A wavy, lustrous pattern or decoration such as is imparted
to linen, silk, metals, etc. See {Water}, v. t., 3,

many self-explaining compounds; as, water drainage;
water gauge, or water-gauge; waterfowl, water-fowl, or
water fowl; water-beaten; water-borne, water-circled,
water-girdled, water-rocked, etc.
[1913 Webster]
{Hard water}. See under {Hard}.
{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.
{Soft water}, water not impregnated with lime or mineral
salts.
{To hold water}. See under {Hold}, v. t.
{To keep one's head above water}, to keep afloat; fig., to

{To make water}.
(a) To pass urine. --Swift.
(b) (Naut.) To admit water; to leak.
{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.
{Water on the chest} (Med.), hydrothorax.
[1913 Webster]

element, will be found in alphabetical order in the
