This order contains a class of animals which live in the water, propel themselves by fins, and have the general form of fishes; yet they are viviparous, and suckle their young; in these respects forming a striking contrast to all the other finny inhabitants of the wave. The principal species are the dolphin, grampus, porpoise, and whale. The latter is remarkable as being by far the largest creature known to the animal kingdom.

THE DOLPHIN.

This animal usually swims in troops, and its motions in the water are performed with such wonderful rapidity, that the French sailors call it la flèche de la mer, or the sea-arrow. St. Pierre, in his "Voyage to the Isle of France," assures us that he saw a dolphin swim with apparent ease round the vessel in which he was sailing, though it was going at the rate of about six miles an hour. A shoal of dolphins followed the ships of Sir Richard Hawkins upwards of a thousand leagues. They were known to be the same, from the wounds they occasionally received from the sailors. They are greedy of almost any kind of scraps that are thrown overboard, and consequently are often caught by means of large iron hooks, baited with pieces of fish and garbage.

The bounding and gambolling of dolphins has attracted the attention of writers and poets in all ages, and is described as being extremely beautiful.

The ancients believed that dolphins attended all cases of shipwreck, and transported the mariners in safety to the shore. Pirœtes, having made captive Arion, the poet, at length determined on throwing him overboard; and it is said that he escaped in safety to the shore on the back of a dolphin.

The poet says,—

"Kind, generous dolphins love the rocky shore,

Where broken waves with fruitless anger roar.

But though to sounding shores they curious come,

Yet dolphins count the boundless sea their home.
