Vegetable sulphur

资料来源 : Webster's Revised Unabridged Dictionary (1913)

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["o]l.) Any one of numerous species of yellow or orange

      common yellow butterfly of the Eastern United States.

      agent. Called also {sulphuric anhydride}, and formerly
      {sulphuric acid}.
