Book I. (Folio), chapter V. ( Razor Back).—­Of this whale little is known but his name.  I have seen him at a distance off Cape Horn.  Of a retiring nature, he eludes both hunters and philosophers.  Though no coward, he has never yet shown any part of him but his back, which rises in a long sharp ridge.  Let him go.  I know little more of him, nor does anybody else.

Book I. (Folio), chapter VI. (Sulphur Bottom).—­Another retiring gentleman, with a brimstone belly, doubtless got by scraping along the Tartarian tiles in some of his profounder divings.  He is seldom seen; at least I have never seen him except in the remoter southern seas, and then always at too great a distance to study his countenance.  He is never chased; he would run away with rope-walks of line.  Prodigies are told of him.  Adieu, Sulphur Bottom!  I can say nothing more that is true of ye, nor can the oldest Nantucketer.

Thus ends book I. (Folio), and now begins book II. (Octavo).

OCTAVOES.* These embrace the whales of middling magnitude, among which at present may be numbered:—­I., the Grampus; II., the Black Fish; III., the Narwhale; IV., the Thrasher; V., the Killer.

Why this book of whales is not denominated the Quarto is very plain.  Because, while the whales of this order, though smaller than those of the former order, nevertheless retain a proportionate likeness to them in figure, yet the bookbinder’s Quarto volume in its dimensioned form does not preserve the shape of the Folio volume, but the Octavo volume does.

Book II. (Octavo), chapter I. (Grampus).—­Though this fish, whose loud sonorous breathing, or rather blowing, has furnished a proverb to landsmen, is so well known a denizen of the deep, yet is he not popularly classed among whales.  But possessing all the grand distinctive features of the leviathan, most naturalists have recognised him for one.  He is of moderate octavo size, varying from fifteen to twenty-five feet in length, and of corresponding dimensions round the waist.  He swims in herds; he is never regularly hunted, though his oil is considerable in quantity, and pretty good for light.  By some fishermen his approach is regarded as premonitory of the advance of the great sperm whale.

Book II. (Octavo), chapter II. (Black Fish).—­I give the popular fishermen’s names for all these fish, for generally they are the best.  Where any name happens to be vague or inexpressive, I shall say so, and suggest another.  I do so now touching the Black Fish, so called because blackness is the rule among almost all whales.  So, call him the Hyena Whale, if you please.  His voracity is well known and from the circumstance that the inner angles of his lips are curved upwards, he carries an everlasting Mephistophelean grin on his face.  This whale averages some sixteen or eighteen feet in length.  He is found in almost all latitudes.
