But the placing of the cap-sheaf to all this blundering business was reserved for the scientific Frederick Cuvier, brother to the famous Baron. In 1836, he published a Natural History of Whales, in which he gives what he calls a picture of the Sperm Whale. Before showing that picture to any Nantucketer, you had best provide for your summary retreat from Nantucket. In a word, Frederick Cuvier’s Sperm Whale is not a Sperm Whale, but a squash.
