Read it through once

But quitting all these unprofessional attempts, let us glance at those pictures of leviathan purporting to be sober, scientific delineations, by those who know. In old Harris’s collection of voyages there are some plates of whales extracted from a Dutch book of voyages, A. D. 1671, entitled “A Whaling Voyage to Spitzbergen in the ship Jonas in the Whale, Peter Peterson of Friesland, master.” In one of those plates the whales, like great rafts of logs, are represented lying among ice-isles, with white bears running over their living backs. In another plate, the prodigious blunder is made of representing the whale with perpendicular flukes.
