Abstract
IN previous communications1 it has been pointed out that certain liquids—termed specific solvents—possess a marked ability to dissolve bituminous coals of low rank at room temperature, a property not shared by other liquids; furthermore, almost all liquids tested have been found to fall definitely into one or other of these classes. The principal specific solvents are primary aliphatic and certain heterocyclic amines.
