From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   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.
      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.
      2. (Zo[94]l.) Any one of numerous species of yellow or orange
            butterflies of the subfamily {Pierin[91]}; as, the clouded
            sulphur ({Eurymus, [or] Colias, philodice}), which is the
            common yellow butterfly of the Eastern United States.
      {Amorphous sulphur} (Chem.), an elastic variety of sulphur of
            a resinous appearance, obtained by pouring melted sulphur
            into water. On standing, it passes back into a brittle
            crystalline modification.
      {Liver of sulphur}. (Old Chem.) See {Hepar}.
      {Sulphur acid}. (Chem.) See {Sulphacid}.
      {Sulphur alcohol}. (Chem.) See {Mercaptan}.
      {Sulphur auratum} [L.] (Old Chem.), a golden yellow powder,
            consisting of antimonic sulphide, {Sb2S5}, -- formerly a
            famous nostrum.
      {Sulphur base} (Chem.), an alkaline sulphide capable of
            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
            sulphur. It is employed chiefly in the production of
            sulphuric acid, and as a reagent in bleaching; -- called
            also {sulphurous anhydride}, and formerly {sulphurous
      {Sulphur ether} (Chem.), a sulphide of hydrocarbon radicals,
            formed like the ordinary ethers, which are oxides, but
            with sulphur in the place of oxygen.
      {Sulphur salt} (Chem.), a salt of a sulphacid; a sulphosalt.
      {Sulphur showers}, showers of yellow pollen, resembling
            sulphur in appearance, often carried from pine forests by
            the wind to a great distance.
      {Sulphur trioxide} (Chem.), a white crystalline solid, {SO3},
            obtained by oxidation of sulphur dioxide. It dissolves in
            water with a hissing noise and the production of heat,
            forming sulphuric acid, and is employed as a dehydrating
            agent. Called also {sulphuric anhydride}, and formerly
            {sulphuric acid}.
      {Sulphur whale}. (Zo[94]l.) See {Sulphur-bottom}.
      {Vegetable sulphur} (Bot.), lycopodium powder. See under

From The Elements (22Oct97) [elements]:
   Symbol: S
   Atomic number: 16
   Atomic weight: 32.064
   Yellow, nonmetallic element belonging to group 16 of the periodic table.
   It is an essential element in living organisms, needed in the amino acids
