Poison \Poi"son\, n. [F. poison, in Old French also, a potion,
fr. L. potio a drink, draught, potion, a poisonous draught,
fr. potare to drink. See {Potable}, and cf. {Potion}.]
1. Any agent which, when introduced into the animal organism,
is capable of producing a morbid, noxious, or deadly
effect upon it; as, morphine is a deadly poison; the
poison of pestilential diseases.
[1913 Webster]

2. That which taints or destroys moral purity or health; as,
the poison of evil example; the poison of sin.
[1913 Webster]

{Poison ash}. (Bot.)
(a) A tree of the genus {Amyris} ({Amyris balsamifera})
found in the West Indies, from the trunk of which a
black liquor distills, supposed to have poisonous
qualities.
(b) The poison sumac ({Rhus venenata}). [U. S.]

{Poison dogwood} (Bot.), poison sumac.

{Poison fang} (Zool.), one of the superior maxillary teeth of
some species of serpents, which, besides having the cavity
for the pulp, is either perforated or grooved by a
longitudinal canal, at the lower end of which the duct of
the poison gland terminates. See Illust. under {Fang}.

{Poison gland} (Biol.), a gland, in animals or plants, which
secretes an acrid or venomous matter, that is conveyed
along an organ capable of inflicting a wound.

{Poison hemlock} (Bot.), a poisonous umbelliferous plant
({Conium maculatum}). See {Hemlock}.

{Poison ivy} (Bot.), a poisonous climbing plant (formerly
{Rhus Toxicodendron}, or {Rhus radicans}, now classified
as {Toxicodendron radicans}) of North America. It is
common as a climbing vine, especially found on tree
trunks, or walls, or as a low, spreading vine or as a
shrub. As a low vine it grows well in lightly shaded
areas, recognizable by growing in clusters of three
leaves. Its leaves are trifoliate, rhombic-ovate, and
variously notched. Its form varies slightly from location
to location, leading to some speculation that it may
consist of more than one species. Many people are poisoned
by it, though some appear resistant to its effects.
Touching the leaves may leave a residue of an oil on the
skin, and if not washed off quickly, sensitive areas of
skin become reddened and develop multiple small blisters,
lasting for several days to several weeks, and causing a
persistent itch. The toxic reaction is due to an oil,
present in all parts of the plant except the pollen,
called {urushiol}, the active component of which is the
compound {pentadecylacatechol} (according to [a

href="http:]/www.jaxmed.com/articles/Diseases/poison_ivy_dermatitis.htm">Charles
H. Booras). See {Poison sumac}. It is related to {poison
oak}, and is also called {mercury}.

{Poison nut}. (Bot.)
(a) Nux vomica.
(b) The tree which yields this seed ({Strychnos
Nuxvomica}). It is found on the Malabar and Coromandel
coasts.

{Poison oak} (Bot.), a dermatitis-producing plant often
lumped together with the poison ivy ({Toxicodendron
radicans}) in common terminology, but more properly
distinguished as the more shrubby {Toxicodendron
quercifolium} (syn. {Toxicodendron diversilobum}), common
in California and Oregon. Opinion varies as to whether the
poison oak and poison ivy are only variants of a single
species. See {poison ivy}, above.

{Poison sac}. (Zool.) Same as {Poison gland}, above. See
Illust. under {Fang}.

{Poison sumac} (Bot.), a poisonous shrub formerly considered
to be of the genus {Rhus} ({Rhus venenata}), but now
classified as {Toxicodendron vernix}; -- also called
{poison ash}, {poison dogwood}, and {poison elder}. It has
pinnate leaves on graceful and slender common petioles,
and usually grows in swampy places. Both this plant and
the poison ivy ({Toxicodendron radicans}, formerly {Rhus
Toxicodendron}) have clusters of smooth greenish white
berries, while the red-fruited species of this genus are
harmless. The tree ({Rhus vernicifera}) which yields the
celebrated Japan lacquer is almost identical with the
poison sumac, and is also very poisonous. The juice of the
poison sumac also forms a lacquer similar to that of
Japan.
[1913 Webster PJC]

Syn: Venom; virus; bane; pest; malignity.

Usage: {Poison}, {Venom}. Poison usually denotes something
received into the system by the mouth, breath, etc.
Venom is something discharged from animals and
received by means of a wound, as by the bite or sting
of serpents, scorpions, etc. Hence, venom specifically
implies some malignity of nature or purpose.
[1913 Webster]


Mercury \Mer"cu*ry\, v. t.
To wash with a preparation of mercury. [Obs.] --B. Jonson.
[1913 Webster]


Mercury \Mer"cu*ry\, n. [L. Mercurius; akin to merx wares.]
1. (Rom. Myth.) A Latin god of commerce and gain; -- treated
by the poets as identical with the Greek Hermes, messenger
of the gods, conductor of souls to the lower world, and
god of eloquence.
[1913 Webster]

2. (Chem.) A metallic element mostly obtained by reduction
from cinnabar, one of its ores. It is a heavy, opaque,
glistening liquid (commonly called {quicksilver}), and is
used in barometers, thermometers, etc. Specific gravity
13.6. Symbol Hg (Hydrargyrum). Atomic weight 199.8.
Mercury has a molecule which consists of only one atom. It
was named by the alchemists after the god Mercury, and
designated by his symbol, [mercury].
[1913 Webster]

Note: Mercury forms alloys, called amalgams, with many
metals, and is thus used in applying tin foil to the
backs of mirrors, and in extracting gold and silver
from their ores. It is poisonous, and is used in
medicine in the free state as in blue pill, and in its
compounds as calomel, corrosive sublimate, etc. It is
the only metal which is liquid at ordinary
temperatures, and it solidifies at about -39[deg]
Centigrade to a soft, malleable, ductile metal.
[1913 Webster]

3. (Astron.) One of the planets of the solar system, being
the one nearest the sun, from which its mean distance is
about 36,000,000 miles. Its period is 88 days, and its
diameter 3,000 miles.
[1913 Webster]

4. A carrier of tidings; a newsboy; a messenger; hence, also,
a newspaper. --Sir J. Stephen. "The monthly Mercuries."
--Macaulay.
[1913 Webster]

5. Sprightly or mercurial quality; spirit; mutability;
fickleness. [Obs.]
[1913 Webster]

He was so full of mercury that he could not fix long
in any friendship, or to any design. --Bp. Burnet.
[1913 Webster]

6. (Bot.) A plant ({Mercurialis annua}), of the Spurge
family, the leaves of which are sometimes used for
spinach, in Europe.
[1913 Webster]

Note: The name is also applied, in the United States, to
certain climbing plants, some of which are poisonous to
the skin, esp. to the {Rhus Toxicodendron}, or poison
ivy.
[1913 Webster]

{Dog's mercury} (Bot.), {Mercurialis perennis}, a perennial
plant differing from {Mercurialis annua} by having the
leaves sessile.

{English mercury} (Bot.), a kind of goosefoot formerly used
as a pot herb; -- called {Good King Henry}.

{Horn mercury} (Min.), a mineral chloride of mercury, having
a semitranslucent, hornlike appearance.
[1913 Webster]
