In describing this siren, singing and smiling, coaxing and cajoling, the author, with modest pride, asks his readers all round, has he once forgotten the laws of politeness, and showed the monster's hideous tail above water? No! Those who like may peep down under waves that are pretty transparent, and see it writhing and twirling, diabolically hideous and slimy, flapping amongst bones, or curling round corpses; but above the water line, I ask, has not everything been proper, agreeable, and decorous, and has any the most squeamish immoralist in Vanity Fair a right to cry fie? When, however, the siren disappears· and dives below, down among the dead men, the water of course grows turbid over her, and it is labour lost to look into it ever so curiously. They look pretty enough when they sit upon a rock, twanging their harps and combing their hair, and sing, and beckon to you to come and hold the looking-glass; but when they sink into their native element, depend on it those mermaids are about no good, and we had best not examine the fiendish marine cannibals, revelling and feasting on their wretched pickled victims (812-13).
