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 of the stomach. Q. Why is it good to walk after dinner? A. Because it makes a man well disposed, and fortifies and strengthens the natural heat, causing the superfluity of the stomach to descend. Q. Why is it wholesome to vomit? A. It purges the stomach of all naughty 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. According to physicians, the spleen is the receptacle of melancholy, and that is black. Q. Why is he lean who hath a large spleen? A. Because the spleen draws much water to itself, which would turn to fat; therefore, men that have a small spleen are fat. Q. Why does the spleen cause men to laugh, as says Isidorus; "We laugh with the spleen, we are angry with the gall, we are wise with the heart, we love with the liver, we feel with the brain, and speak with the lungs"? A. The reason is, the spleen draws much melancholy to it, being its proper seat, the which melancholy proceeds from sadness, and is there consumed; and the cause failing, the effect doth so likewise. And by the same reason the gall causes anger, for choleric men are often angry, because they have much gall. _Of Carnal Copulation._ Q. Why do living creatures use carnal copulation? A. Because it is most natural in them to get their like. Q. What is carnal copulation? A. It is a mutual action of male and female, with instruments ordained for that purpose to propagate their kind.
