But how now, Ishmael? How is it, that you, a mere oarsman in the fishery, pretend to know aught about the subterranean parts of the whale? Did erudite Stubb, mounted upon your capstan, deliver lectures on the anatomy of the Cetacea; and by help of the windlass, hold up a specimen rib for exhibition? Explain thyself, Ishmael. Can you land a full-grown whale on your deck for examination, as a cook dishes a roast-pig? Surely not. A veritable witness have you hitherto been, Ishmael; but have a care how you seize the privilege of Jonah alone; the privilege of discoursing upon the joists and beams; the rafters, ridgepole, sleepers, and under-pinnings, making up the framework of leviathan; and belike of the tallow-vats, dairy-rooms, butteries, and cheeseries in his bowels.
