The fraction of coal-tar succeeding the carbolic oil, viz. the creosote
oil, does not at present supply the colour manufacturer with any raw
materials beyond the small proportion of naphthalene which separates from
it in a very impure condition as "creosote salts." This oil consists of a
mixture of the hi
