Q. Wherefore doth it proceed, that bread which is made with salt is
lighter than that which is made without it, considering that salt is
very heavy of itself? A. Although bread is very heavy of itself, yet the
salt dries it and makes it light, by reason of the heat which it hath;
and the more heat there is in it, the better the bread is, and the
lighter and more wholesome for the body.

Q. Why is not new bread good for the stomach? A. Because it is full of
moistness, and thick, hot vapours, which do corrupt the blood, and hot
bread is blacker than cold, because heat is the mother of blackness, and
because the vapours are not gone out of it.

Q. Why do lettuces make a man sleep? A. Because they engender gross
vapours.

Q. Why do the dregs of wine and oil go to the bottom, and those of honey
swim uppermost? A. Because the dregs of wine and oil are earthly, and

made subtle; on which account the dregs are most light and hot, and
therefore go uppermost.

action, and judging the same to be pleasant and delightful, and
therefore the imagination draweth the like of it in conceit and stirs up
the body by the gestures.

Q. Why does much sleep cause some to grow fat and some lean? A. Those
who are of ill complexion, when they sleep, do consume and digest the
superfluities of what they have eaten, and therefore become fat. But
such as are of good complexion, when they sleep are more cold, and

Q. How much, and from what cause do we suffer hunger better than thirst?
A. When the stomach hath nothing else to consume, it consumeth the
phlegm and humours which it findeth most ready and most at hand; and
therefore we suffer hunger better than thirst, because the heat hath
nothing to refresh
