Sulphur
(gcide) | Sulphur \Sul"phur\, n. [L., better sulfur: cf. F. soufre.]
1. (Chem.) A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as
pyrites) and sulphates (as gypsum), or native in volcanic
regions, in vast beds mixed with gypsum and various earthy
materials, from which it is melted out. Symbol S. Atomic
weight 32. The specific gravity of ordinary octohedral
sulphur is 2.05; of prismatic sulphur, 1.96.
[1913 Webster]
Note: It is purified by distillation, and is obtained as a
lemon-yellow powder (by sublimation), called flour, or
flowers, of sulphur, or in cast sticks called roll
sulphur, or brimstone. It burns with a blue flame and a
peculiar suffocating odor. It is an ingredient of
gunpowder, is used on friction matches, and in medicine
(as a laxative and insecticide), but its chief use is
in the manufacture of sulphuric acid. Sulphur can be
obtained in two crystalline modifications, in
orthorhombic octahedra, or in monoclinic prisms, the
former of which is the more stable at ordinary
temperatures. Sulphur is the type, in its chemical
relations, of a group of elements, including selenium
and tellurium, called collectively the sulphur group,
or family. In many respects sulphur resembles oxygen.
[1913 Webster]

acting as a base in the formation of sulphur salts
according to the old dual theory of salts. [Archaic]
Sulphur dioxide (Chem.), a colorless gas, SO2, of a
pungent, suffocating odor, produced by the burning of

sulphuric acid, and as a reagent in bleaching; -- called
also sulphurous anhydride, and formerly {sulphurous
acid}.

formed like the ordinary ethers, which are oxides, but
with sulphur in the place of oxygen.

sulphur in appearance, often carried from pine forests by
the wind to a great distance.

A very large glandular and vascular organ in the visceral
cavity of all vertebrates.

Note: Most of the venous blood from the alimentary canal
passes through it on its way back to the heart; and it
secretes the bile, produces glycogen, and in other ways
changes the blood which passes through it. In man it is
situated immediately beneath the diaphragm and mainly
on the right side. See Bile, Digestive, and
Glycogen. The liver of invertebrate animals is
usually made up of c[ae]cal tubes, and differs
materially, in form and function, from that of
vertebrates.

for the sake of its liver, which often yields several
barrels of oil. It has gill rakers, resembling whalebone,
by means of which it separates small animals from the sea
water. Called also basking shark, bone shark,
hoemother, homer, and sailfish; it is sometimes
referred to as whale shark, but that name is more

[1913 Webster]Sulphur \Sul"phur\, n. [L., better sulfur: cf. F. soufre.]
1. (Chem.) A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as
pyrites) and sulphates (as gypsum), or native in volcanic
regions, in vast beds mixed with gypsum and various earthy
materials, from which it is melted out. Symbol S. Atomic
weight 32. The specific gravity of ordinary octohedral
sulphur is 2.05; of prismatic sulphur, 1.96.
[1913 Webster]
Note: It is purified by distillation, and is obtained as a
lemon-yellow powder (by sublimation), called flour, or
flowers, of sulphur, or in cast sticks called roll
sulphur, or brimstone. It burns with a blue flame and a
peculiar suffocating odor. It is an ingredient of
gunpowder, is used on friction matches, and in medicine
(as a laxative and insecticide), but its chief use is
in the manufacture of sulphuric acid. Sulphur can be
obtained in two crystalline modifications, in
orthorhombic octahedra, or in monoclinic prisms, the
former of which is the more stable at ordinary
temperatures. Sulphur is the type, in its chemical
relations, of a group of elements, including selenium
and tellurium, called collectively the sulphur group,
or family. In many respects sulphur resembles oxygen.
[1913 Webster]
2. (Zool.) Any one of numerous species of yellow or orange

sulphur. It is employed chiefly in the production of
sulphuric acid, and as a reagent in bleaching; -- called
also sulphurous anhydride, and formerly {sulphurous
acid}.

(b) A heavy, corrosive, oily liquid, H2SO4, colorless
when pure, but usually yellowish or brownish, produced
by the combined action of sulphur dioxide, oxygen
(from the air), steam, and nitric fumes. It attacks
and dissolves many metals and other intractable
substances, sets free most acids from their salts, and
is used in the manufacture of hydrochloric and nitric
acids, of soda, of bleaching powders, etc. It is also
powerful dehydrating agent, having a strong affinity
for water, and eating and corroding paper, wood,
clothing, etc. It is thus used in the manufacture of
ether, of imitation parchment, and of nitroglycerin.
It is also used in etching iron, in removing iron
scale from forgings, in petroleum refining, etc., and
in general its manufacture is the most important and
fundamental of all the chemical industries. Formerly
called vitriolic acid, and now popularly vitriol,
and oil of vitriol.
