Those men who have this
course of blood, are kept from many infirmities, such as dropsy, plague,

Q. Why are the Jews much subject to this disease? A. Because they eat
much phlegmatic and cold meats, which breed melancholy blood, which is
purged with the flux. Another reason is, motion causes heat and heat
digestion; but strict Jews neither move, labour nor converse much, which
breeds a coldness in them, and hinders digestion, causing melancholic
blood, which is by this means purged out.
_Of the Heart._
Q. Why are the lungs light, spongy and full of holes? A. That the air
may be received into them for cooling the heart, and expelling humours,
because the lungs are the fan of the heart; and as a pair of bellows is
raised up by taking in the air, and shrunk by blowing it out, so
likewise the lungs draw the air to cool the heart, and cast it out, lest
through too much air drawn in, the heart should be suffocated.
Q. Why is the flesh of the lungs white? A. Because they are in continual
motion.
Q. Why have those beasts only lungs that have hearts? A. Because the
lungs be no part for themselves, but for the heart, and therefore, it
were superfluous for those creatures to have lungs that have no hearts.
Q. Why do such creatures as have no lungs want a bladder? A.
