such drink no water to make their meat digest and need no bladder for

Q. Why is the heart in the midst of the body? A. That it may import life
to all, parts of the body, and therefore it is compared to the sun,
which is placed in the midst of the planets, to give light to them all.
Q. Why only in men is the heart on the left side? A. To the end that the
heat of the heart may mitigate the coldness of the spleen; for the
spleen is the seat of melancholy, which is on the left side also.
Q. Why is the heart first engendered; for the heart doth live first and
die last? A. Because the heart is the beginning and original of life,
and without it no part can live. For of the seed retained in the matrix,
there is first engendered a little small skin, which compasses the seed;
whereof first the heart is made of the purest blood; then of blood not
so pure, the liver; and of thick and cold blood the marrow and brain.
Q. Why are beasts bold that have little hearts? A. Because in a little
heart the heat is well united and vehement, and the blood touching it,
doth quickly heat it and is speedily carried to the other parts of the
body, which give courage and boldness.
