" The Lachrymose Leeches,' Aunt Josephine said, 'are quite different from regular leeches. They each have six rows of very sharp teeth ad one very sharp nose - they can smell even the smallest bit of food from far far away. The Lachrymose Leeches are usually quite harmless, preying only on small fish. But if they smell food on a human they will swarm around him "
