Abstract
THE much-discussed problem of whether marine birds drink sea-water has recently led to the unexpected discovery that the kidney is not always the major organ of salt excretion. It was found that in cormorants (Phalacrocorax auritus) much salt may be excreted extra-renally in the form of a highly concentrated solution of sodium chloride, discharged from the nasal (salt) glands1.
