But the love of the galeus toward her young ones is beyond the affection and clemency of any the tamest of creatures; for they lay an egg, which being hatched, they nourish and carry the young about not outwardly, but within their own bowels, as if they could not breed their young without a second birth. When the young ones are somewhat grown, they put them forth again, and teach them to swim close by themselves, then resume them again through their mouths into their bellies, and afford them nourishment and safe retirement in their bodies, till they are able to shift for themselves. No less admirable is the care of the tortoise, as to the bringing forth and preserving her young. For she retires out of the sea to lay; but not being able to stay long upon the land, she hides her eggs in the sand, covering them over gently with the lightest of the gravel; and when she has thus sufficiently and assuredly concealed them, some report that she marks and streaks the place with her feet, that she may be able to know it again; others affirm that the female, being turned upon her back upon the sand by the male, leaves her particular marks and signatures behind her. However it be, this is most wonderful, that after waiting forty days (for in so many the eggs come to break) she returns, and knowing where the treasure lies, as well as any man understands where he hides his gold, she opens them with great joy and alacrity. 34. Many observations like to these are made of the crocodile. But such is its skill in choosing a place for breeding, that no man can explain it by reason or conjecture. Whence it comes that the foreknowledge of this creature is imputed more to divinity than reason. For neither farther nor nearer, but just so far as the Nile that year will increase and cover the land, thither she goes forth and lays her eggs; which the countrymen finding, are able to tell one another how far the river will overflow that year. So truly does that animal measure for herself, that though she live in the water, she may lay her eggs dry. But the young ones being hatched, whichsoever of them, so soon as they are come to life, does not seize whatever comes next—either upon a fly, or a worm, or a straw, or a tuft of grass—with his mouth, the dam presently tears him to pieces with her teeth. But those that are fierce and active she loves and cherishes, according to the judgment of the wisest men, imparting her affection by the rules of judgment, not by the sway of passion. The sea-calves also bring forth upon the dry lands; but then fetching out their young ones by degrees, they give them a taste of the sea-water, and presently lead them out again; and this they often do, till custom has made them bold, and brought them to love a sea life.
