Illustrations

(a) A, the holder of a negotiable instrument payable to bearer, delivers it to B's agent to keep for B. The instrument has been negotiated.

(b) A, the holder of a negotiable instrument payable to bearer, which is in the hands of A's banker, who is at the time the banker of B, directs the banker to transfer the instrument to B's credit in the banker's account with B. The banker does so, and accordingly now possesses the instrument as B's agent. The instrument has been negotiated, and B has become the holder of it.
