1. (Chem.) The complex mixture of volatile, liquid,
inflammable hydrocarbons, occurring naturally, and usually
called crude petroleum, mineral oil, or rock oil.
Specifically: That portion of the distillate obtained in
the refinement of petroleum which is intermediate between
the lighter gasoline and the heavier benzine, and has a
specific gravity of about 0.7, -- used as a solvent for
varnishes, as a carburetant, illuminant, etc.
[1913 Webster]

2. (Chem.) One of several volatile inflammable liquids
obtained by the distillation of certain carbonaceous
materials and resembling the naphtha from petroleum; as,
Boghead naphtha, from Boghead coal (obtained at Boghead,
Scotland); crude naphtha, or light oil, from coal tar;
wood naphtha, from wood, etc.
[1913 Webster]

Note: This term was applied by the earlier chemical writers
to a number of volatile, strong smelling, inflammable
liquids, chiefly belonging to the ethers, as the
sulphate, nitrate, or acetate of ethyl. --Watts.
