Q. Why is the sparkling in cats’ eyes and wolves’ eyes seen in the dark and not in the light? A. Because that the greater light doth darken the lesser; and therefore, in a greater light the sparkling cannot be seen; but the greater the darkness, the easier it is seen, and is more strong and shining.
Q. Why is the sight recreated and refreshed by a green colour? A. Because green doth merely move the sight, and therefore doth comfort it; but this doth not, in black or white colours, because these colours do vehemently stir and alter the organ and instrument of the sight, and therefore make the greater violence; and by how much the more violent the thing is which is felt or seen the more it doth destroy and weaken the sense.
Of the Nose.
Q. Why doth the nose stand out further than any other part of the body. A. 1. Because the nose is, as it were, the sink of the brain, by which the phlegm of the brain is purged; and therefore it doth stand forth, lest the other parts should be defiled. 2. Because the nose is the beauty of the face, and doth smell.
Q. Why hath a man the worst smell of all creatures? A. Because man hath most brains of all creatures; and, therefore, by exceeding coldness and moisture, the brain wanteth a good disposition, and by consequence, the smelling instrument is not good, yea, some men have no smell.
Q. Why have vultures and cormorants a keen smell? A. Because they have a very dry brain; and, therefore, the air carrying the smell, is not hindered by the humidity of the brain, but doth presently touch its instrument; and, therefore, vultures, tigers and other ravenous beasts, have been known to come five hundred miles after dead bodies.
Q. Why did nature make the nostrils? A. 1. Because the mouth being shut we draw breath in by the nostrils, to refresh the heart. 2. Because the air which proceedeth from the mouth doth savour badly, because of the vapours which rise from the stomach, but that which we breathe from the nose is not noisome. 3. Because the phlegm which doth proceed from the brain is purged by them.
Q. Why do men sneeze? A. That the expulsive virtue and power of the sight should thereby be purged, and the brain also from superfluities; because, as the lungs are purged by coughing, so is the sight and brain by sneezing; and therefore physicians give sneezing medicaments to purge the brain; and thus it is, such sick persons as cannot sneeze, die quickly, because it is a sign their brain is wholly stuffed with evil humours, which cannot be purged.
