The Aethiop
The purchaser of a black servant was persuaded that the color of his skin arose from dirt contracted through the neglect of his former masters. On bringing him home he resorted to every means of cleaning, and subjected the man to incessant scrubbings. The servant caught a severe cold, but he never changed his color or complexion.
What's bred in the bone will stick to the flesh.

The Ass and the Mule
A muleteer set forth on a journey, driving before him an Ass and a Mule, both well laden. The Ass, as long as he traveled along the plain, carried his load with ease, but when he began to ascend the steep path of the mountain, felt his load to be more than he could bear. He entreated his companion to relieve him of a small portion, that he might carry home the rest; but the Mule paid no attention to the request. The Ass shortly afterwards fell down dead under his burden. Not knowing what else to do in so wild a region, the Muleteer placed upon the Mule the load carried by the Ass in addition to his own, and at the top of all placed the hide of the Ass, after he had skinned him. The Mule, groaning beneath his heavy burden, said to himself: I am treated according to my deserts. If I had only been willing to assist the Ass a little in his need, I should not now be bearing, together with his burden, himself as well.

The Belly and the Members
The members of the Body rebelled against the Belly, and said, Why should we be perpetually engaged in administering to your wants, while you do nothing but take your rest, and enjoy yourself in luxury and self-indulgence?' The Members carried out their resolve and refused their assistance to the Belly. The whole Body quickly became debilitated, and the hands, feet, mouth, and eyes, when too late, repented of their folly.
