Herman Melville: Moby Dick

CHAPTER 105: Does the Whale's Magnitude Diminish?--Will He Perish?

Inasmuch, then, as this Leviathan comes floundering down upon us from the head-waters of the Eternities, it may be fitly inquired, whether, in the long course of his generations, he has not degenerated from the original bulk of his sires.

But upon investigation we find, that not only are the whales of the present day superior in magnitude to those whose fossil remains are found in the Tertiary system (embracing a distinct geological period prior to man), but of the whales found in that Tertiary system, those belonging to its latter formations exceed in size those of its earlier ones.

Of all the pre-adamite whales yet exhumed, by far the largest is the Alabama one mentioned in the last chapter, and that was less than seventy feet in length in the skeleton. Whereas, we have already seen, that the tape-measure gives seventy-two feet for the skeleton of a large sized modern whale. And I have heard, on whalemen's authority, that Sperm Whales have been captured near a hundred feet long at the time of capture.

But may it not be, that while the whales of the present hour are an advance in magnitude upon those of all previous geological periods; may it not be, that since Adam's time they have degenerated?

Assuredly, we must conclude so, if we are to credit the accounts of such gentlemen as Pliny, and the ancient naturalists generally. For Pliny tells us of Whales that embraced acres of living bulk, and Aldrovandus of others which measured eight hundred feet in length--Rope Walks and Thames Tunnels of Whales! And even in the days of Banks and Solander, Cooke's naturalists, we find a Danish member of the Academy of Sciences setting down certain Iceland Whales (reydan-siskur, or Wrinkled Bellies) at one hundred and twenty yards; that is, three hundred and sixty feet. And Lacepede, the French naturalist, in his elaborate history of whales, in the very beginning of his work (page 3), sets down the Right Whale at one hundred metres, three hundred and twenty-eight feet. And this work was published so late as A.D. 1825.
