at Henneberg. A small amount of iron is sometimes added to
make it whiter and harder. It is essentially identical
with the Chinese alloy packfong. It was formerly much
used for tableware, knife handles, frames, cases, bearings
of machinery, etc., but is now largely superseded by other
white alloys.

s["o]lv, Goth. silubr, Russ. serebro, Lith. sidabras; of
unknown origin.]
1. (Chem.) A soft white metallic element, sonorous, ductile,
very malleable, and capable of a high degree of polish. It
is found native, and also combined with sulphur, arsenic,
antimony, chlorine, etc., in the minerals argentite,
proustite, pyrargyrite, ceragyrite, etc. Silver is one of
the "noble" metals, so-called, not being easily oxidized,
and is used for coin, jewelry, plate, and a great variety
of articles. Symbol Ag (Argentum). Atomic weight 107.7.
Specific gravity 10.5.
[1913 Webster]
Note: Silver was known under the name of luna to the ancients
and also to the alchemists. Some of its compounds, as
the halogen salts, are remarkable for the effect of
light upon them, and are used in photography.
[1913 Webster]
2. Coin made of silver; silver money.
[1913 Webster]
3. Anything having the luster or appearance of silver.
[1913 Webster]
4. The color of silver.

Note: Silver is used in the formation of many compounds of
obvious meaning; as, silver-armed, silver-bright,
silver-buskined, silver-coated, silver-footed,

Nickel \Nick"el\, n. [G., fr. Sw. nickel, abbrev. from Sw.
kopparnickel copper-nickel, a name given in derision, as it
was thought to be a base ore of copper. The origin of the
second part of the word is uncertain. Cf. Kupfer-nickel,
Copper-nickel.]
1. (Chem.) A bright silver-white metallic element of atomic
number 28. It is of the iron group, and is hard,
malleable, and ductile. It occurs combined with sulphur in
millerite, with arsenic in the mineral niccolite, and with
arsenic and sulphur in nickel glance. Symbol Ni. Atomic
weight 58.70.
[1913 Webster]
Note: On account of its permanence in air and inertness to
oxidation, it is used in the smaller coins, for plating
iron, brass, etc., for chemical apparatus, and in
certain alloys, as german silver. It is magnetic, and
is very frequently accompanied by cobalt, both being
found in meteoric iron.
[1913 Webster]
2. A small coin made of or containing nickel; esp., a
five-cent piece. [Colloq. U.S.]
[1913 Webster]
Nickel silver, an alloy of nickel, copper, and zinc; --
