First: The uncertain, unsettled condition of this science of Cetology is in the very vestibule attested by the fact, that in some quarters it still remains a moot point whether a whale be a fish. In his System of Nature, A.D. 1776, Linnaeus declares, "I hereby separate the whales from the fish." But of my own knowledge, I know that down to the year 1850, sharks and shad, alewives and herring, against Linnaeus's express edict, were still found dividing the possession of the same seas with the Leviathan.
The grounds upon which Linnaeus would fain have banished the whales from the waters, he states as follows: "On account of their warm bilocular heart, their lungs, their moveable eyelids, their hollow ears, penem intrantem feminam mammis lactantem," and finally, "ex lege naturae jure meritoque." I submitted all this to my friends Simeon Macey and Charley Coffin, of Nantucket, both messmates of mine in a certain voyage, and they united in the opinion that the reasons set forth were altogether insufficient. Charley profanely hinted they were humbug.
Be it known that, waiving all argument, I take the good old fashioned ground that the whale is a fish, and call upon holy Jonah to back me. This fundamental thing settled, the next point is, in what internal respect does the whale differ from other fish. Above, Linnaeus has given you those items. But in brief they are these: lungs and warm blood; whereas, all other fish are lungless and cold blooded.
Next: how shall we define the whale, by his obvious externals, so as conspicuously to label him for all time to come. To be short, then, a whale is a spouting fish with a horizontal tail. There you have him.
However contracted, that definition is the result of expanded meditation. A walrus spouts much like a whale, but the walrus is not a fish, because he is amphibious. But the last term of the definition is still more cogent, as coupled with the first. Almost any one must have noticed that all the fish familiar to landsmen have not a flat, but a vertical, or up-and-down tail. Whereas, among spouting fish the tail, though it may be similarly shaped, invariably assumes a horizontal position.
By the above definition of what a whale is, I do by no means exclude from the leviathanic brotherhood any sea creature hitherto identified with the whale by the best informed Nantucketers; nor, on the other hand, link with it any fish hitherto authoritatively regarded as alien.* Hence, all the smaller, spouting and horizontal tailed fish must be included in this ground-plan of cetology. Now, then, come the grand divisions of the entire whale host.
*I am aware that down to the present time, the fish styled Lamatins and Dugongs (Pig-fish and Sow-fish of the Coffins of Nantucket) are included by many naturalists among the whales. But as these pig-fish are a noisy, contemptible set, mostly lurking in the mouths of rivers, and feeding on wet hay, and especially as they do not spout, I deny their credentials as whales; and have presented them with their passports to quit the Kingdom of Cetology.
First: According to magnitude I divide the whales into three primary BOOKS (subdivisible into CHAPTERS), and these shall comprehend them all, both small and large.
I. THE FOLIO WHALE; II. the OCTAVO WHALE; III. the DUODECIMO WHALE.
As the type of the FOLIO I present the Sperm Whale; of the OCTAVO, the Grampus; of the DUODECIMO, the Porpoise.
FOLIOS. Among these I here include the following chapters:- I. The Sperm Whale; II. the Right Whale; III. the Fin Back Whale; IV. the Humpbacked Whale; V. the Razor Back Whale; VI. the Sulphur Bottom Whale.
In shape, he differs in some degree from the Huzza Porpoise, being of a less rotund and jolly girth; indeed, he is of quite a neat and gentleman-like figure. He has no fins on his back (most other porpoises have), he has a lovely tail, and sentimental Indian eyes of a hazel hue. But his mealy-mouth spoils him. Though his entire back down to his side fins is of a deep sable, yet a boundary line, distinct as the mark in a ship's hull, called the "bright waist," that line streaks him from stem to stern, with two separate colors, black above and white below. The white comprises part of his head, and the whole of his mouth, which makes him look as if he had just escaped from a felonious visit to a meal-bag. A most mean and mealy aspect!
His oil is much like that of the common porpoise.
Beyond the DUODECIMO, this system does not proceed, inasmuch as the Porpoise is the smallest of the whales. Above, you have all the Leviathans of note. But there are a rabble of uncertain, fugitive, half-fabulous whales, which, as an American whaleman, I know by reputation, but not personally. I shall enumerate them by their fore-castle appellations; for possibly such a list may be valuable to future investigators, who may complete what I have here but begun. If any of the following whales, shall hereafter be caught and marked, then he can readily be incorporated into this System, according to his Folio, Octavo, or Duodecimo magnitude:- The Bottle-Nose Whale; the Junk Whale; the Pudding-Headed Whale; the Cape Whale; the Leading Whale; the Cannon Whale; the Scragg Whale; the Coppered Whale; the Elephant Whale; the Iceberg Whale; the Quog Whale;the Blue Whale; &c. From Icelandic, Dutch, and old English authorities, there might be quoted other lists of uncertain whales, blessed with all manner of uncouth names. But I omit them as altogether obsolete; and can hardly help suspecting them for mere sounds, full of Leviathanism, but signifying nothing.
Finally: It was stated at the outset, that this system would not be here, and at once, perfected. You cannot but plainly see that Ihave kept my word. But I now leave my cetological System standing thus unfinished, even as the great Cathedral of Cologne was left, with the cranes still standing upon the top of the uncompleted tower. For small erections may be finished by their first architects; grand ones, true ones, ever leave the copestone to posterity. God keep me from ever completing anything. This whole book is but a draught- nay, but the draught of a draught. Oh, Time, Strength, Cash, and Patience!
