Aristotimus
A certain mule that was wont to carry salt, in fording a river, by accident happened to stumble, by which means the water melting away the salt, when the mule rose again he felt himself much lighter; the cause of which the mule was very sensible of, and laid it up in his memory, insomuch that every time he forded the same river, he would always stoop when he came into the deepest part, and fill his vessels with water, crouching down, and leaning sometimes to one side, sometimes to the other. Thales hearing this, ordered the vessels to be well filled with wool and sponges, and to drive the mule laden after that manner. But then the mule, as he was wont, filling his burthens with water, reasoned with himself that he had ill consulted his own benefit, and ever afterwards, when he forded the same river, was so careful and cautious, that he would never suffer his burthens so much as to touch the water by accident.
