What's the difference between anaesthetic and ether?

Anaesthetic


Definition:

Ether


Definition:

  • (n.) A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.
  • (n.) Supposed matter above the air; the air itself.
  • (n.) A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether.

  • (n.) Any similar oxide of hydrocarbon radicals; as, amyl ether; valeric ether.
