Man sees with his eyes, hears with his ears, smells with his nose, tastes with his mouth, and feels with his fingers. One man's eyes see better, another man's see worse. One hears from a distance, and another is deaf. One has keen senses and smells a thing from a distance, while another smells at a rotten egg and does not perceive it. One can tell a thing by the touch, and another cannot tell by touch what is wood and what paper. One will take a substance in his mouth and will find it sweet, while another will swallow it without making out whether it is bitter or sweet. Just so the different senses differ in strength in the animals. But with all the animals the sense of smell is stronger than in man. When a man wants to recognize a thing, he looks at it, listens to the noise that it makes, now and then smells at it, or tastes it; but, above all, a man has to feel a thing, to recognize it. But nearly all animals more than anything else need to smell a thing.
