The Cachalot (Sperm Whale) is not only better armed than the True Whale (Greenland or Right Whale) in possessing a formidable weapon at either extremity of its body, but also more frequently displays a disposition to employ these weapons offensively and in manner at once so artful, bold, and mischievous, as to lead to its being regarded as the most dangerous to attack of all the known species of the whale tribe.
