Rocks

I should say that those New England rocks on the sea-coast, which Agassiz imagines to bear the marks of violent scraping contact with vast floating icebergs—I should say, that those rocks must not a little resemble the Sperm Whale in this particular. It also seems to me that such scratches in the whale are probably made by hostile contact with other whales; for I have most remarked them in the large, full-grown bulls of the species.

A word or two more concerning this matter of the skin or blubber of the whale.
