To these three kinds of seals already mentioned we may, perhaps, add a fourth, described in Anson's voyages by the name of the _sea-lion_. These are found in great numbers on the Magellanic coasts, and at the island of Juan Fernandes, in the South Sea. The sea-lion resembles our seal, which is very common in the same latitudes, but it is much larger, being from eleven to eighteen feet long, and from eight to eleven in circumference, when it has acquired its full growth. They are so fat that when the skin is taken off, the blubber is about a foot thick all round the body, and from a single animal more than ninety gallons of oil may be drawn. They are, at the same time, very full of blood, and which, when deeply wounded, springs out with amazing force. Upon the throat of one of these animals being cut, two hogsheads of blood were taken out, besides what then remained in its body. Their skins are covered with a short hair of a brownish colour, but blackish on the tail and feet. Their toes are united by a membrane, which does not reach to their extremity, and each of them are terminated by a claw. The sea-lion differs from the common seal not only in its size and bulk, but also by other characters. The male has a kind of thick crest, or trunk, hanging from the end of its upper jaw, about five or six inches long. This character is not seen in the females, and forms a very striking distinction between them. The strong males collect together a flock of females, and permit no other male to approach them. These animals are truly amphibious; they remain all the summer in the sea, and go upon land in the winter; at which season the females bring forth, but never produce above one or two at a litter, which they suckle. The sea-lions, while they are on land, feed on the herbage which grows by the sides of the sea. They are of a very heavy and drowsy nature, and delight to sleep in the mire. Though very indolent and difficult to waken, yet at those times they commonly fix some as centinels near the place where they sleep; and it is said, that these centinels give loud warnings when any danger is near. Their voices are very loud and of various tones; sometimes grunting like hogs, and sometimes neighing like horses. The males often fight about the females and wound one another desperately with their teeth. The flesh of these animals is not disagreeable to eat; particularly the tongue, which is as good as that of the ox. They are very easily killed, as they cannot defend themselves, nor fly from their enemies: they are so exceedingly heavy, that they move with great difficulty, and turn themselves with still greater. Those that hunt them have only to guard against coming too near their teeth, which are very strong, and with which they inflict deadly wounds.
