chylus from the stomach.  The thick guts are three, the blind gut, colon, and right gut.  The blind is a thick and short gut, having one mouth, in which the ilium and colon meet:  it receives the excrements, and conveys them to the colon.  This colon hath many windings, that the excrements pass not away too fast:  the right gut is straight, and conveys the excrements to the fundament, whose lower part is bound up with certain muscles called sphincters, that the excrements may be the better contained, until such time as a man be willing to go to the stool.  In the midst of these guts is situated the mesenterium or midriff, composed of many veins, arteries, and much fat, serving chiefly to sustain the guts.  All these parts serve the first concoction.  To the second, which is busied either in refining the good nourishment or expelling the bad, is chiefly belonging the liver, like in colour to congealed blood, the shop of blood, situate in the right hypochondry, in figure like to a half-moon, generosum membrum Melancthon styles it, a generous part; it serves to turn the chylus to blood, for the nourishment of the body.  The excrements of it are either choleric or watery, which the other subordinate parts convey.  The gall placed in the concave of the liver, extracts choler to it:  the spleen, melancholy; which is situate on the left side, over against the liver, a spongy matter, that draws this black choler to it by a secret virtue, and feeds upon it, conveying the rest to the bottom of the stomach, to stir up appetite, or else to the guts as an excrement.  That watery matter the two kidneys expurgate by those emulgent veins and ureters.  The emulgent draw this superfluous moisture from the blood; the two ureters convey it to the bladder, which, by reason of his site in the lower belly, is apt to receive it, having two parts, neck and bottom:  the bottom holds the water, the neck is constringed with a muscle, which, as a porter, keeps the water from running out against our will.

Members of generation are common to both sexes, or peculiar to one; which, because they are impertinent to my purpose, I do voluntarily omit.

Middle Region.] Next in order is the middle region, or chest, which comprehends the vital faculties and parts; which (as I have said) is separated from the lower belly by the diaphragma or midriff, which is a skin consisting of many nerves, membranes; and amongst other uses it hath, is the instrument of laughing.  There is also a certain thin membrane, full of sinews, which covereth the whole chest within, and is called pleura, the seat of the disease called pleurisy, when it is inflamed; some add a third skin, which is termed mediastinus, which divides the chest into two parts, right and left; of this region the principal part is the heart, which is the seat and fountain of life, of heat, of spirits, of pulse and respiration—­the sun of our body, the king and sole commander of it—­the seat and organ of all passions and affections.
