(3) Usages and Practice
Usages and practice developed under a statute is indicative of the meaning ascribed to its words by contemporary opinion and in case of an ancient statute, such reference to usage and practice is an admissible external aid to its construction. But this principle is not applicable to a modern statute and it is confined to the construction of ambiguous language used in old statute.
