A negotiable receipt may be negotiated by the indorsement of the person to whose order the goods are, by the terms of the receipt, deliverable. Such indorsement may be in blank, to bearer or to a specified person. If indorsed to a specified person, it may be again negotiated by the indorsement of such person in blank, to bearer or to another specified person. Subsequent negotiation may be made in like manner.
