    <p>Of the Right Whale, the best outline pictures are in Scoresby; but they are drawn on too small a scale to convey a desirable impression. He has but one picture of whaling scenes, and this is a sad deficiency, because it is by such pictures only, when at all well done, that you can derive anything like a truthful idea of the living whale as seen by his living hunters. &#8212; Herman Melville, <i>Moby Dick</i></p>
