The village of Hawsker, with its massive though modern church, can be seen across the fields towards the west, but it does not offer sufficient attractions to divert you from the cliffs, unless you have a desire to see in one or two of the fields, gateways and rubbing-posts formed of whales' jaws, suggestive of the days when Whitby carried on a thriving trade with the great cetaceans.
Now as to the question: How were Cirripedia converted by natural selection into Rhizocephala? A considerable number of existing Cirripedia settle exclusively or chiefly upon living animals; on Sponges, Corals, Mollusks, Cetaceans, Turtles, Sea-Snakes, Sharks, Crustaceans, Sea Urchins, and even on Acalephs.
"Nothing, my friends; at least of that which passes the limit of truth to get to fable or legend. Nevertheless, there must be some ground for the imagination of the story-tellers. One cannot deny that poulps and cuttlefish exist of a large species, inferior, however, to the cetaceans. Aristotle has stated the dimensions of a cuttlefish as five cubits, or nine feet two inches.
Imagine a thick soft lump absolutely crammed with fat, and completely immovable, because it is glued down along its whole length to the bottom of the mouth, and you will have a good idea of this strange tongue, which in the whale, the largest of the cetaceans, attains to the length of twenty-five feet and the width of twelve, and of itself alone furnishes the whale-fishers with from five to six tons of oil.
"If we do not know every one of them, if nature still keeps ichthyological secrets from us, nothing is more admissible than to accept the existence of fish or cetaceans of new species or even new genera, animals with a basically 'cast-iron' constitution that inhabit strata beyond the reach of our soundings, and which some development or other, an urge or a whim if you prefer, can bring to the upper level of the ocean for long intervals.
Look!" the Canadian exclaimed, his voice full of excitement. "It's approaching! It's coming toward us! It's thumbing its nose at me! It knows I can't do a blessed thing to it!" Ned stamped his foot. Brandishing an imaginary harpoon, his hands positively trembled. "These cetaceans," he asked, "are they as big as the ones in the northernmost seas?" "Pretty nearly, Ned."
In the gray lizards of our walls we find teeth again, but very different from any that we have hitherto seen. In the first place, they are not content with their usual place on the edge of the jaws, but encroach upon the surface of the palate, where they stretch out in close lines. Besides, they are even still less like teeth than the great nails in the jaws of the cetaceans.
And this was the public tribute, from the same pen, to the first of the cetaceans that died through too much publicity: "The community was shocked to hear of the death of one of Barnum's whales yesterday morning. Death apparently loves a shining mark.
Cetaceans are whales; and if I had been consulted on the matter, I should have joined this order and the last together, under whatever name was thought most appropriate.
We can also understand the apparent paradox, that the very same characters are analogical when one class or order is compared with another, but give true affinities when the members of the same class or order are compared one with another: thus the shape of the body and fin-like limbs are only analogical when whales are compared with fishes, being adaptations in both classes for swimming through the water; but the shape of the body and fin-like limbs serve as characters exhibiting true affinity between the several members of the whale family; for these cetaceans agree in so many characters, great and small, that we cannot doubt that they have inherited their general shape of body and structure of limbs from a common ancestor.
