e bladder is shut?
A. Some say sweatings; others, by a small skin in the bladder, which
opens and lets in the urine. Urine is a certain and not deceitful
messenger of the health or infirmity of man. Men make white urine in the
morning, and before dinner red, but after dinner pale, and also after
supper.

Q. Why is it hurtful to drink much cold water? A. Because one contrary
doth hinder and expel another; water is very cold, and lying so in the
stomach, doth hinder digestion.

Q. Why is it unwholesome to drink new wine? A. 1. It cannot be digested;
therefore it causeth the belly to swell, and a kind of bloody flux. 2.
It hinders making water.

Q. Why do physicians forbid us to labour presently after dinner? A. 1.
Because the motion hinders the virtue and power of digestion. 2.
Because stirring immediately after dinner causes the different parts of
the body to draw the meat to them, which often breeds sickness. 3.
Because motion makes the food descend before it is digested. And after
supper it is good to walk a little, that the food may go to the bottom

Q. Why is it good to walk after dinner? A. Because it makes a man well

humours, expelling them, which would breed again if they should remain
in it; and purges the eyes and head, clearing the brain.

Q. How comes sleep to strengthen the stomach and the digestive faculty?
A. Because in sleep the heat draws inwards, and helps digestion; but
when we awake, the heat returns, and is dispersed through the body.

_Of the Gall and Spleen._

Q. How come living creatures to have a gall? A. Because choleric humours
are received into it, which through their acidity helps the guts to
expel superfluities; also it helps digestion.

Q. How comes the jaundice to proceed from the gall? A. The humour of the
gall is bluish and yellow; therefore when its pores are stopped the
humour cannot go into the sack thereof, but are mingled with the blood,
wandering throughout all the body and infecting the skin.

Q. Why hath a horse, mule, ass or cow a gall? A. Though these creatures
have no gall in one place, as in a purse or vessel, yet they have one
dispersed in small veins.

Q. How comes the spleen to be black? A. It is occasioned by terrestrial
and earthy matter of a black colour. Ac
