Q. Why do wolves grow grisly? A. To understand this question, note the difference between grayness and grisliness: grayness is caused through defect of natural heat, but grisliness through devouring and heat. The wolf being a devouring animal beast, he eateth gluttonously without chewing, and enough at once for three days; in consequence of which, gross vapours are engendered in the wolfs body, which cause grisliness. Grayness and grisliness have this difference; grayness is only in the head, but grisliness all over the body. Q. Why do horses grow grisly and gray? A. Because they are for the most part in the sun, and heat naturally causes putrefaction; therefore the matter of air doth putrefy, and in consequence they are quickly peeled. Q. Why are not women bald? A. Because they are cold and moist, which are the causes that the hair remaineth; for moistness doth give nutriment to the hair, and coldness doth bind the pores. Q. Why are not blind men naturally bald? A. Because the eye hath moisture in it, and that moisture which should pass through by the substance of the eyes doth become a sufficient nutriment for the hair, and therefore they are seldom bald. Q. Why doth the hair stand on end when men are afraid? A. Because in time of fear the heat doth go from the outward parts of the body into the inward to help the heart, and so the pores in which the hair is fastened are shut up; after which stopping and shutting up of the pores, the standing up of the hair doth follow. _Of the Head._ Q. Why is a man’s head round? A. Because it contains in it the moistest parts of the living creature; and also that the brain may be defended thereby, as with a shield. Q. Why is the head not absolutely long, but somewhat round? A. To the end that the three creeks and cells of the brain might the better be distinguished: that is, the fancy in the forehead, the discoursing or reasonable part in the middle, and memory in the hindermost part. Q. Why doth a man lift up his head towards the heavens when he doth imagine? A. Because the imagination is the fore part of the head or brain, and therefore it lifteth up itself, that the creeks or cells of the imagination may be opened, and that the spirits which help the imagination, and are fit for that purpose, having their concourse thither, may help the imagination. Q. Why doth a man, when he museth or thinketh of things past, look towards the earth? A. Because the cell or creek which is behind, is the creek or chamber of the memory; and therefore that looketh towards the heavens when the head is bowed down, and so that cell is open, to the end that the spirits which perfect the memory should enter in. Q. Why is not the head fleshy, like other parts of the body? A. Because the head would be too heavy, and would not stand steadily. Also, a head loaded with flesh betokens an evil complexion.
