To those who have not chanced specially to study the subject, it may possibly seem strange, that fishes not commonly exceeding four or five feet should be marshalled among whales ⁠—a word, which, in the popular sense, always conveys an idea of hugeness. But the creatures set down above as Duodecimoes are infallibly whales, by the terms of my definition of what a whale is⁠— i.e. a spouting fish, with a horizontal tail.
