Webster's 1913 Dictionary
  1. \Vol"a*tile\, a. [F. volatil, L. volatilis, fr. volare
    to fly, perhaps akin to velox swift, E. velocity. Cf.
    1. Passing through the air on wings, or by the buoyant force
       of the atmosphere; flying; having the power to fly. [Obs.]
    2. Capable of wasting away, or of easily passing into the
       a["e]riform state; subject to evaporation.
    Note: Substances which affect the smell with pungent or
          fragrant odors, as musk, hartshorn, and essential oils,
          are called volatile substances, because they waste away
          on exposure to the atmosphere. Alcohol and ether are
          called volatile liquids for a similar reason, and
          because they easily pass into the state of vapor on the
          application of heat. On the contrary, gold is a fixed
          substance, because it does not suffer waste, even when
          exposed to the heat of a furnace; and oils are called
          fixed when they do not evaporate on simple exposure to
          the atmosphere.
    3. Fig.: Light-hearted; easily affected by circumstances;
