Thefinn-fish is of the length of a whale, but in bulk the whale is three times as big. They know the finn-fish by the finns that are upon his back, near unto his tail, and also by his vehement blowing and spouting up of the water, which the whale doth not do. His knob on the head is split in length, that is at his blowing hole, through which he forces up the water higher than the whale, and with more fierceness, which is not so high as that of the whale, neither is the back bended or dented in so much. His lips are of a brownish colour, and like a twisted rope. On his upper lip the whalebone hangs as it doth on the whale; but whether he doth open and shut his mouth there are different opinions: some believe that he cannot open his mouth, yet this is not true; but he doth not always run open mouth'd, that the whalebone may not hang out of his mouth at the sides as it doth in whales, or else he can open his mouth if he pleases.
