SEA-Serpent, a monstrous creature, said to inhabit the northern seas about Greenland and on the coasts of Norway. Pontoppidan, in his natural history of Norway, brings several testimonies of mariners who pretend to have seen it; but no distinct account of its form and properties has been obtained. According to the relations there given, the sea-serpent is thicker than a large hog'shead, and upwards of 600 feet in length; with large blue eyes, resembling two polished pewter-plates, when seen at a distance. Sometimes it raises part of its body out of the water, so that its head will reach above the highest masts; and it is thought to be able to sink the largest man of war by throwing itself across it: yet it is said to be a timid animal; and not only has never been known to do hurt, but flies from the slightest appearance of injury, &c. See Plate CCLXV.
