Q. Whereof doth it proceed that want of
sleep doth weaken the brain and body? A. Much watching doth engender choler, the which being hot both dry up and lessen the humours which serve the brain, the head, and other parts of the body.
Q. Wherefore doth vinegar so readily staunch blood? A. From its cold virtue, for all cold is naturally binding, and vinegar being cold, hath the like property.
Q. Why is sea-water salter in summer than in winter? A. From the heat of the sun, seeing by experiment that a salt thing being heated becometh more salt.
Q. Why do men live longer in hot regions than in cold? A. Because they may be more dry, and by that means the natural heat is better preserved in them than in cold countries.
Q. Why is well-water seldom or ever good? A. All water which standeth still in the spring and is never heated by the sunbeams, is very heavy, and hath much matter in it, and therefore wanting the heat of the sun, is naught.
Q. Why do men sleep better and more at ease on the right side than on the left? A. Because when they be on the left side, the lungs do lie upon and cover the heart, which is on that side under the pap; now the heart, the fountain of life, being thus occupied and hindered with the lungs, cannot exercise its own
proper operation, as being overmuch heated with the lungs lying upon it, and therefore wanting the refreshment of the air which the lungs do give it, like the blowing of a pair of bellows, is choked and suffocated, but by lying on the right side, those inconveniences are avoided.
Q. What is the reason that old men sneeze with great difficulty? A. Because that through their coldness their arteries are very narrow and close, and therefore the heat is not of force to expel the cold.
Q. Why doth a drunken man think that all things about him do turn round? A. Because the spirits which serve the sight are mingled with vapours and fumes, arising from the liquors he has drunk; the overmuch heat causeth the eye to be in continual motion, and the eye being round, causeth all things about it to seem to go round.
