From 50 to 100 yards, however, are sometimes traversed by the Fish at one leap; and the height to which it rises from the surface of the water, is occasionally such as to carry it over the deck of a ship. On the other hand, there are seve- ral among the diving Birds, which use their wings as instruments of progression beneath the water,— in other words, as fins. The most remarkably-constructed of all these is the Penguin, in which the wings are so short as to be incapable of answering any other purpose ; but there are several species, in which they may be used as organs of flight in the air, without losing water. 668, There are several animals that can sustain themselves for a short time in the air, by the aid of an expanded surface formed by an extension of the skin, and serving as a parachute. This is the case, for instance, with the Galeopithecus or Flying Lemur (Fig. 223), the Flying Squirrel, and the Flying Opos- sum, which have the skin stretched out on either side like a cloak, supported by the anterior and posterior extremities, and by the tail. By this parachute-like surface they are sustained in extensive leaps from bough to bough; though it does not enable them to support themselves in the air for any length of.
