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

specific gravity of about 0.7, -- used as a solvent for
varnishes, as a carburetant, illuminant, etc.
[1913 Webster]
