The turtles live on land and in the water, like snakes and frogs. They breed their young from eggs. These eggs they lay on the ground, and they do not hatch them, but the eggs burst themselves, like fish spawn, and the turtles crawl out of them. There are small turtles, not larger than a saucer, and large ones, seven feet in length and weighing seven hundredweights. The large turtles live in the sea.

One turtle lays in the spring hundreds of eggs. The turtle’s shells are its ribs. Men and other animals have each rib separate, while the turtle’s ribs are all grown together into a shell. But the main thing is that with all the animals the ribs are inside the flesh, while the turtle has the ribs on the outside, and the flesh beneath them.
