Sharp stones [are] under him
And yet give him no pain nor uneasiness;
he spreadeth sharp pointed things upon the mire;
and makes his bed of them and lies upon them; as sharp stones, as before, shells of fishes, broken pieces of darts, arrows, and javelins thrown at him, which fall around him: this does not so well agree with the crocodile, the skin of whose belly is soft and thin; wherefore dolphins plunge under it and cut it with a thorn, as Pliny F8 relates, or with spiny fins F9; but with the whale, which lies among hard rocks and sharp stones, and large cutting pieces of ice, as in the northern seas.
