(a) Unless the warehouse receipt provides otherwise, a warehouse shall
keep  separate  the goods covered by each receipt so as to permit at all
times identification and delivery of  those  goods.  However,  different
lots of fungible goods may be commingled.
  (b)  If different lots of fungible goods are commingled, the goods are
owned in common by the persons entitled thereto  and  the  warehouse  is
severally  liable  to  each owner for that owner's share. If, because of
overissue, a mass of fungible goods is  insufficient  to  meet  all  the
receipts  the  warehouse  has  issued  against  it, the persons entitled
include  all  holders  to  which  overissued  receipts  have  been  duly
negotiated.
