humour, called melancholy, which is transmitted thereto from the milt, giveth warning to shut in the food. The tongue doth make the first essay, and tastes it; the teeth do chew it, and the stomach doth receive, digest, and chylify it. The mesaraic veins suck out of it what is good and fit, leaving behind the excrements, which are, through special conduits for that purpose, voided by an expulsive faculty. Thereafter it is carried to the liver, where it being changed again, it by the virtue of that new transmutation becomes blood. What joy, conjecture you, will then be found amongst those officers when they see this rivulet of gold, which is their sole restorative? No greater is the joy of alchemists, when after long travail, toil, and expense they see in their furnaces the transmutation. Then is it that every member doth prepare itself, and strive anew to purify and to refine this treasure. The kidneys through the emulgent veins draw that aquosity from thence which you call urine, and there send it away through the ureters to be slipped downwards; where, in a lower receptacle, and proper for it, to wit, the bladder, it is kept, and stayeth there until an opportunity to void it out in his due time. The spleen draweth from the blood its terrestrial part, viz., the grounds, lees, or thick substance settled in the bottom thereof, which you term melancholy. The bottle of the gall subtracts from thence all the superfluous choler; whence it is brought to another shop or work-house to be yet better purified and fined, that is, the heart, which by its agitation of diastolic and systolic motions so neatly subtilizeth and inflames it, that in the right side ventricle it is brought to perfection, and through the veins is sent to all the members. Each parcel of the body draws it then unto itself, and after its own fashion is cherished and alimented by it. Feet, hands, thighs, arms, eyes, ears, back, breast, yea, all; and then it is, that who before were lenders, now become debtors. The heart doth in its left side ventricle so thinnify the blood, that it thereby obtains the name of spiritual; which being sent through the arteries to all the members of the body, serveth to warm and winnow the other blood which runneth through the veins. The lights never cease with its lappets and bellows to cool and refresh it, in acknowledgment of which good the heart, through the arterial vein, imparts unto it the choicest of its blood. At last it is made so fine and subtle within the rete mirabile, that thereafter those animal spirits are framed and composed of it, by means whereof the imagination, discourse, judgment, resolution, deliberation, ratiocination, and memory have their rise, actings, and operations.
