Somewhat higher than the fish in the scale of life is the frog. Although he begins life as a fish, and in the tadpole state breathes by gills, he soon discards the water-diluted air of the pond, and with perfect lungs boldly inhales the pure air of the upper world. His life as a tadpole, although so fish-like, is much inferior to true fish life: for though the fish has not the perfect lung, he has a modification of it which he fills with air, not for breathing purposes, but as an air-sac to make him float like a bubble in the water. Will he rise to the surface? he inflates the air-bladder. Will he sink to the bottom? he compresses the air-bladder. But in the frog the air-bladder changes into the lungs, and is never the delicate balloon which floats the fish in aqueous space. When the frog's lungs are perfected, his gills close, and he forever abandons fish-life, though being a cold-blooded creature he needs comparatively little air, and delights to return to his childhood's home in the bottom of the pond. But although he can stay under water for a long time, he is obliged to hold his breath while there, and when he would breathe must come to the surface to do so. It is possible to drown him by holding him under water.
he Second Punic War was not so much a contest between the powers of two great nations--between Carthage and Rome--as between the individual genius of Hannibal on one hand, and the combined energies of the Roman people on the other. The position of Hannibal was indeed very peculiar. His command in Spain, and the powerful army there, which was entirely at his own disposal, rendered him in great measure independent of the government at Carthage, and the latter seemed disposed to devolve all responsibility upon him. Even now they did little themselves to prepare for the impending contest. All was left to Hannibal, who, after the conquest of Saguntum, had returned once more to New Carthage for the winter, and was there actively engaged in preparations for transporting the scene of war in the ensuing campaign from Spain into Italy. At the same time he did not neglect to provide for the defense of Spain and Africa during his absence. In the former country he placed his brother Hasdrubal, with a considerable army, great part of which was composed of Africans, while he sent over a large body of Spanish troops to contribute to the defense of Africa, and even of Carthage itself.
