The Achaean exiles, whose numbers were now reduced from 1000 to 300, landed in Greece (B.C. 151) with feelings exasperated by their long confinement, and ready to indulge in any rash enterprise against Rome. Polybius, who had returned with the other exiles, in vain exhorted them to peace and unanimity, and to avoid a hopeless struggle with the Roman power. Shortly afterward an adventurer laid claim to the throne of Macedonia (B.C. 149). He was a man of low origin called Andriscus, but he pretended to be the son of Perseus, and assumed the name of Philippus. At first he met with some success, and defeated the Roman Praetor Juventius, but, after reigning scarcely a year, he was conquered and taken prisoner by Q. Metellus.
n No. 3 the nest is seen full of eggs, and the excellent father now comes out in his best light as their guardian and protector. He watches over them with ceaseless care, freeing them from parasites, and warding off the attacks of would-be enemies who desire to devour them, even though the intruder be several times his own size. The spines on his back here stand him once more in good stead: for small as he is, the stickleback is not an antagonist to be lightly despised: he can inflict a wound which a perch or a trout knows how to estimate at its full value. But that is not all the good parent's duty. He takes the eggs out of the nest every now and then with his snout, airs them a little in the fresh water outside, and then replaces and rearranges them, so that all may get a fair share of oxygen and may hatch out about simultaneously. It is this question of oxygen, indeed, which gives the father fish all the greatest trouble. That necessary of life is dissolved in water in very small quantities; and it is absolutely needed by every egg in order to enable it to undergo those vital changes which we know as hatching. To keep up a due supply of oxygen, therefore, the father stickleback ungrudgingly devotes laborious days in poising himself delicately just above the nest, as you see in No. 3, and fanning the eggs with his fins and tail, so as to set up a constant current of water through the centre of the barrel. He sits upon the eggs just as truly as a hen does; only, he sits upon them, not for warmth, but for aeration.
