In an indictment for obtaining property by a false pretence, or for stealing by a clerk or servant, or person acting in the capacity of a clerk or servant, an averment as to obtaining or stealing money shall be sustained by proof that the accused obtained or converted any coin or bank note, or any part of the value of either, although such coin or note was delivered to him in order that some part of the value thereof should be returned to the person who delivered the same or to some other person, and has been returned accordingly.
