CHAP. I. That a nice and strict observation of any of those six things nor natural, except Exercise, is no legitimate means for the preservation of health, or prevention of diseases.  
MEdicina, that Art, which in our English tongue is commonly styled by the term of Physic, that hath for its object disease's, either to be prevented or removed, and for its end or scope the health of humane bodies, doth cosist of two general parts, viz. Prophylactical and Therapeutical. T●● Prophylactical part of Physic she● how diseases may be prevented▪ The Therapeutical part discover how they may be removed 〈◊〉 cured, after they are once contracted.  
I shall first treat of the Prophy●ctical part, and show, how by t●● common Medicaments, diseases m● as well or better be prevented, th● by that various and multiform 〈◊〉 byrinth, wherein most Physicians this time do wander. Not tha● pretend how by these Medicament all manner of diseases in all pers● whatsoever, shall or may be so certainly prevented, as that no ●stemper can possibly happen u● any of those persons that use the● for if this could be effected, m● would then be immortal. But speak comparatively, that as mu● or more may be effected toward the prevention of diseases by this Compendious, than by that Elaborate and more tedious proceeding.  
The way and means which hath been, and is at this time in use amongst Physicians to prevent diseases, is to give prescriptions unto several persons, according to their various temperaments, complexions, or constitutions, concerning Air, Diet, Excretion, Sleep, the Passions of the mind, and Exercise: Things, as they are termed by Physicians, not natural, (for all things that the Physician hath to do with, are ranked into three orders, viz. Res naturales, non naturales, & praeter naturam) which things not natural, if they shall be tightly proportioned, and made correpondent with each particular constitution, and so continued in their proportion, may without all peradventure in a great measure prevent diseases. But to make and continue such an exquisite proportion, is altogether impossible.  
To make a stone or powder 〈◊〉 that quality, that it shall convert a● metals into gold that shall be touched by it, is certainly a direct way 〈◊〉 increase riches. Yet if such a ston● or powder cannot by humane A● be produced, it is an absurd thing t● historize the dignity and worth o● that imaginary stone, and propound it for the intent and purpose aforesaid.  
The case is the same in the proportioning Air, Diet, Sleep, &c things not natural, unto particular constitutions. I deny not but th●● those things not natural, may an● ought to be appropriated to disease● for the cure of the same; yet tha● they cannot be proportioned to particular constitutions, for prevention of diseases, I shall show by discoursing upon them particularly.  
And suppose they could be so proportioned, yet would it be a very difficult thing to be performed, in respect of that necessity which providence hath cast almost upon all men, enforcing them to the contrary. As for example: Suppose that such particular Air, or Diet, should be absolutely necessary for the preservation of health, for all persons of a sanguine or phlegmatic complexion in this City, how many would there be who would have no convenience for the use of either? If a certain particular air, should be absolutely necessary for the preservation of the health of some particular persons, even Kings themselves might be pitied in this respect, who by keeping the same air, must either lose their health, or by changing it, endanger the loss of their Kingdom.  
When a certain King demanded of a Philosopher, in what part of his Kingdom it would be most convenient for him to live; The Philosopher called for a Bulls Hid, and throwing it down, desired the Ki●● to tread upon it; who treading upo● the sides, found by experience th● the contrary sides, by reason of th● stiffness of the Leather would fly 〈◊〉 in his face; but when he trod in th● midst, the whole Hide was couchant and still.  
Now if Kings themselves at● oftentimes necessitated to retain t●● same air, much more may we conceive Subjects and inferior people to be: Insomuch that if it were s● that a certain particular Air, an●● Diet, etc. were absolutely necessary for all persons, according to the several constitutions, for the preservation of their health, Providence might in some measure be complained of, for enforcing the greate● part of mankind unto so hard choice, as the loss either of the● health or estate. But as in reason, is not probable that Divine Providence hath dealt so hardly with u● so experience will evince the contrary. For, 'tis well known by ex●●rience, that but one of those six ●●ngs not natural, which is Exercise, 〈◊〉 much concerned in the preservation of health, or prevention of diseases; of which afterwards in its proper place.   

CHAP. II. How air can be appropriated to particular constitutions for preservation of health.  
IT is a very hard thing in the general to distinguish of air under the same climate, whether it be better or worse for the preservation of the health of humane bodies. For we know that here in England, in those places which are reputed to have the worst air, as in Fenny and Marshy places, the inhabitants are as strong in constitution, and generally do live as long as others, who breath that air which is accounted most pure and healthful. And 〈◊〉 those persons that are so healthful and live so long, in that suppose unwholesome air, are of different complexions, some sanguine, som● choleric, some phlegmatic, an● others melancholic, or else mi●● of these, yet different from each other, according to that infinite v●riety of proportion of the foresai● humours, which is easilier conceiv●● than expressed.  
Insomuch that in the same ai● which is supposed to be the wor●● persons of all kinds of temperaments or complexions enjoy thei● health, whilst, in the mean time others altogether as different in thei● complexions, in the very purest ai● are either soon cut off with death, o● else most part of their life-time d● groan under the heavy burden o● sickness and diseases.  
Now although it may be here objected, that many who have a general Cachexy upon them, who cannot perfectly and throughly enjoy their health, do find in themselves an alteration to the better, by the change of air; yet we are not to ascribe this to the quality of the air, but to the difference, to the alternation, vicissitude, or change, which procureth a fermentation of the mass of blood, the next and immediate cause of health. For certain it is, that change of air doth ferment the mass of blood, of what quality soever the changed air be; and it is known by common experience, that the change of air, although from the better to the worse, doth oftentimes remove Cachectical distempers.  
Who would not think, but that a clear and dry air, should be far better for persons that are inclined unto Aguish distempers, than to live in a Ship at Sea, especially in these Northern Climates, where the air is more cold and watery? Yet is it known by experience, that even Quartain Agues have been cured b● going to Sea, by changing a bette● for a reputed worse air: The one reason without all peradventure, this, viz. A just fermentation the mass of blood caused by the change of air.  
But here it may also be objected that some bodies that are healthful do find an alteration to the worse, b● the change of air.  
To this, I answer; That those a● bodies of a more delicate and fi● habit, who being in perfect health cannot but be somewhat altered, b● the change of their accustomed A● For if the change of air can ma● an alteration to the better in bodi● that are distempered, it may as we● make an alteration to the worse 〈◊〉 other bodies, that are in perfe● health; especially in such body's 〈◊〉 are of a more tender constitution seeing also that health doth depen● upon a just, not an under nor over fermentation of the mass of blood.  
By this it may appear, how vain a thing it is for prevention of Diseases, to prescribe a particular air, to some particular constitutions; whereas that alteration which happeneth unto some bodies, is caused not by the quality, but by change of the air.   

CHAP. III. Whether a strict observation of Diet, may conduce to the prevention of Diseases.  
IN the next place let us inquire into the nature of Diet, how that can be appropriated unto particular complexions, for prevention of Diseases.  
And this I find impossible to be done. The way and means to effect this, should be, first to inquire into the Nature and Constitution of the Person to be Dieted, then to prescribe such a Diet as may rectify what is conceived to be amiss in him. 〈◊〉 for example: to prescribe such diet as may lenify sharp Humour● such a diet as may incrassate ser● and thin humours, and attem● those that are viscous and thi● etc.  
But how is it possible for the wis● Physician, to know the particular Constitution of any person living 'Tis confessed, it is a matter of 〈◊〉 great difficulty, to make a very probable Conjecture of the Temperament, whether it be Phlematick or Choleric, etc. but touching the diet, this is not suffiment. There is that in Nature whi●● the Greeks call 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉, a prop● and particular temperament, un● each Individuum, which by a sec●● instinct, inclines many person's 〈◊〉 desire, and enables them to dige● such diet as many Physician's woul● think (upon the account of th● Temperament which appears unt● them) as hurtful as poison unto them. And on the contrary, many there are who would be sick even ●nto death, if they should make use of some such diet, as Physicians would prescribe them. How many are there of Phlegmatic Constitutions, who do nauseate and loath Honey, the great Attenuatour of Phlegm and viscous humours, and that which by almost all Physicians is commonly prescribed, for the same purpose? And again, there are many whose bodies seem to abound with viscous and gross humours; yet by a secret instinct of Nature, resulting from that 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 or proper temperament, they do not only desire, but do also very easily digest Cheese, and Fish, and other such things which most Physicians would strictly forbid them.  
You shall have two persons of the same Temperament, as near as any Physician is able to judge; the one shall desire Cheese, and very easily digest it; the other shall be sick even at the very sight of it. The o●● shall abhor Wine, and strong Drin● who perhaps never drank any thin● beside water, in all his life-time; an● the other shall be unsatisfied, and si●● at his stomach, if he drink not either wine, or strong drink, at all his meal● The one shall abhor Flesh-meat, an● preserve his health by refusing it and the other, though of the sam● Temperament, as far as any Physician can judge, shall much desire it and be very healthful all his life-time by reason of the use of it.  
So that to prescribe a diet, is no● so much the way and means to prevent, as to produce diseases; seeing that Nature, the wisest of Physicians, hath provided for every particular person, a different and distinct palate, which (if not vitiated and corrupted by some accident) doth truly distinguish of meats, relishing or disgusting them according as they are wholesome or unwholesome for the body.  
'Tis well known in Martial Discipline, that he who stands Sentinel, ●ath and aught to have full power to examine all particular persons, be●ore he admit them entrance into the Garrison. Now suppose that some Deputy-Governour in the governor's absence, should so far question the discretion of him that stands Sentinel, as to take away all his power of Examining; and in stead thereof, give him in charge to admit, without Examination, all persons that have black hair, and to exclude others: This might be a means to exclude some Friends, and to admit of some Enemies, and so to destroy the Garrison.  
Every Physician is Nature's Lieutenant, or Deputy Governor; the Palate is that Sentinel which stands to examine every thing that is ingested into the body. Now if the Physician, Nature's Lieutenant, should take away the Palates power of examination, and in stead thereof, give only some general precepts, wh●● and what not, is to be ingested; 〈◊〉 this means he shall, by excluding friends, and admitting enemies, r●ther destroy, than preserve 〈◊〉 bodies health and welfare.   

CHAP. FOUR Whether Excretion by siege or sto● besides that by sweat and urine, necessary to preserve health.  
ANother way and means in u● amongst Physicians, to preser● health, and to prevent diseases, to provide and take care that the be due excretion, that the body 〈◊〉 kept Laxative or Soluble, whereby all that excrementitious matte● that shall by any accident be collected in the mass of blood, ma● conveniently, by siege or stool, b● separated, excerned and purged that so the mass of blood may 〈◊〉 reserved sincere and pure, in all re●●●ts fit for the use of nature.  
This, I confess, seems to be somewhat pregnant with reason; yet notwithstanding experience doth clearly confute it.  
'Tis known by experience, that ●any, who are most careful, by Art, ●o preserve their bodies Soluble and ●axative, are seldom throughly and perfectly healthful; yet many others, ●●o are continually Costive, who go ●ot to stool every day, and perhaps, sometimes not above once in three ●r four days, do enjoy their perfect ●ealth for many years together. although it cannot be denied, but ●●at most persons, who are naturally ●axative, are also very healthful: ●et is it much to be suspected, ●hether that Solubility of body, ●hich some have beyond others, do ●ot proceed, rather from a deficiency, than perfection of Nature: seeing also that most men are Costive, ●●d they that are Laxative, are of the weakest constitutions.  
Through the viscosity of humour's, obstructing the urinato● passages, through the coldness of t● body, thickness of the skin, 〈◊〉 closeness of the pores, where● transpiration is hindered, industrio● nature being put to her shifts, is ●cessitated to vent a great part of th● serous humidity, by siege or stoo● which she had rather throw out sweat and urine. So that this Solubility of body, may at the best, styled nothing else, than a good eff● of a bad cause. Although it be w● to be liked, that Nature hath length, found out a new channel, ●vent her superfluous humidity; y● had it been much better, if she h● never been so far put to her shifts to seek it.  
Yet is it the common and gene● received opinion, that Solubility body doth proceed from the perfection of Nature; and that in 〈◊〉 bodies she doth primarily intent 〈◊〉 how can this be any other than a ●gar error? Whereas those that 〈◊〉 commonly Costive, are such as 〈◊〉 eat, drink, sleep, digest, excise, and perform all other offices 〈◊〉 Nature, perfectly and exactly: 〈◊〉 on the other side, those that ●on every small occasion are sub●●t unto Solubility, or looseness, 〈◊〉 either aged persons, sickly and ●akly young Children, Women in ●ilde-bed, consumptive persons; 〈◊〉 else others, that are known by ex●rience to be of the weakest con●tutions. And besides, that it is ●e intent and scope of Nature, to ●parate any excrementitious mat●●r, that may be collected in the ●ass of blood, by throwing it off together with the serous part, and con●ying it through the Ureters and ●res by urine and sweat, it may clearly appear by that large quantity of Hypostasis or Sediment that i● in the urine of those persons that are recovering from sickness, and by their great inclination, at that t● unto sweeting.  
So that whereas solubility of b● was never primarily intended 〈◊〉 Nature, but only made use of 〈◊〉 accident, to purge the blood; 〈◊〉 make such provision that the bo● be kept soluble, must needs be far from preserving health, and p●venting diseases, that it may ve● well be thought to be a means, 〈◊〉 disturbing Nature, to destroy heal● and to cause distempers.   

CHAP. V Whether it be Necessary for the Pres●vation of Health, to observe Ru● concerning sleep.  
ANother means to preser● health, in use amongst Phy●tians, is to prescribe rules concer●ing sleep, that it be not excessi● nor deficient, but moderate agreeable to the Constitution. Now w● must know that sleep is nothing else, us a cessation of the exercise of the ●mal Faculties, caused by a de●ency of spirits, which spirits 〈◊〉 the only promoters or setters 〈◊〉 work, of the exercise of those ●mal Faculties.  
The spirits are nothing else but a ●re Halitus, or thin matter breathed ●n the Mass of blood, which as ●y are in a continual production ●ayes arising from the Mass of ●od; so are they also in perpetual ●ence, drawn out by External ejects, and continually losing them●ves in the air.  
Now by the exercise of the animal guiltless, as motion of the body, ●ing, etc. or by the senses, Hear● Seeing, etc. entertained by ●ternal objects; the expense is greater than the procreation or eduction of the spirits. But by ●cessation of the exercise of those ●mal Faculties, the spirits are again suited and restored: for by that means the production becomes greater than the expense.  
Here is also to be noted, that how much the exercise of the ani● faculties shall be more intense remiss; so much the more or 〈◊〉 sleep will be required for the resti●tion of the lost spirits.  
From hence it may appear 〈◊〉 sleep is by no means to be approbated unto the constitution, bu● necessarily required by Nature p●portionably to the expense of spi● caused by the exercise of the ani● Faculties.  
Now although there be s● Lethargical and sleepy diseases, we are not in the least to conc●● that sleep is the cause, but the educt and effect, or at least the adj● or concomitant of such diseases.  
The restitution of decayed spi● cannot possibly be the cause of disease whatsoever, but rath● preservative against diseases: wherefore to prescribe rules for the ●ation of sleep, is in some sort to ●ulate the strength of Nature, and ●estrain the body from being too ●ate and lively.  
●f sleep, be it never so much, can any cause of disease; How comes ●o pass, that young Children who ●nd the greatest part of the first ●rter, in continual sleep, become ●re lively and thriving, than others ●o sleep less? Or how happens it ●t some aged persons spin out the ●ed of their lives to a great ex●t by much sleeping?   

CHAP. VI ●ether the Regulation of the Passions of the Mind, be a Legitimate means to prevent Diseases.  
ANother means in use amongst Physicians, for the preserva●n of health, is the Regulation of ●e affections or passions of the mind. Now although it cannot be deni● but that the Irregular passions of 〈◊〉 mind may do much hurt to the ●dy, and that there is somewhat 〈◊〉 to be attributed to the discre●● of every person, as to the regulate of his passions: Yet must we h● presuppose that health of body is ●cessarily required for the regulate of all humane affections. Insom● that the regulation of our affecti●● is rather to be conceived an eff●● product, and result, than any ca● of health. As to the affections 〈◊〉 passions, as anger, joy, fear, gr●● etc. there can scarce be men's sa● except it be in corpore sano. For know by experience, that sick, ag● and consumptive persons, are 〈◊〉 more peevish and fretful than other Although, when the body is dissed, the mind, or soul itself, 〈◊〉 be in perfect health; yet the affe●ons, which are the souls attendant must needs be disturbed and disq●eted, whensoever the body shall ●●emper'd, because their very es●ce, or being, doth depend upon 〈◊〉 crasis, or temperament of the ●dy. And so on the contrary, they ●st needs be altogether as much in 〈◊〉 souls reach, to be regulated and ●mmanded by her when the body healthful. It is in some sense a ●●st certain and infallible Axiom, Mores sequuntur humores) viz. that 〈◊〉 manners, i. e. the affections of 〈◊〉 mind, have dependence upon 〈◊〉 humours of the body.  
From hence it cannot but be ●ought more rational, that provi●on be made first for the body, that be preserved in health, that so the actions of the mind may be re●ated, than to prescribe the regu●ion of the affections as a cause and 〈◊〉 server of health.   

CHAP. VII. That the chief preserver of health Exercise, because it doth ferm● the mass of blood; and that whosoever else doth cause fermentati●● may be used as a fit Succedane●● for Exercise.  
NOw am I arrived unto the si● and last, which is a true a legitimate means, prescribed by Physicians, for the preservation 〈◊〉 health, and prevention of diseas● and this is bodily Exercise. 〈◊〉 thing so well known by experient to preserve health, that they 〈◊〉 do moderately use it, stand in ne● of no other preventing Physics This is that which makes the labouring man's sleep pleasant and sw●● unto him: This is that which she● the Justice and equality of Divi●● Providence, distributing the happiness of this world, in some good ●asure alike unto the Sons of men. ●or they who are necessitated, and constrained to work hard for a live●●od, are recompensed with the ●●ition of health, than which no●●ng is more comfortable and de●●●ble in this world. And certainly, ●●e the virtue and efficacy of Ex●●cise, for the prevention of diseases, ●tter known, or more seriously ●●sidered, many Millions in this ●●rld, might be happy in the injoy●nt of their health, who are now miserable by reason of the want of it. 〈◊〉 many there are, who by reason ●●ameness, or debilitation, through ●he accident, are rendered incapable of exercising: and many more, ●o are prevented by their professi●● whose employment is Writing, ●●ving, Studying, or some such like, ●hich enforceth them unto a still 〈◊〉 sedenary life; and as many, who though they do sometimes Exer●●●e, yet not so often, nor unto that degree and measure which Nature requires. Besides that innumer●●● multitude of others, who hav● contracted a depraved habit of E●minacy and softness of living, 〈◊〉 think it a thing burdensome, 〈◊〉 troublesome to Nature, although the preservation of their health Exercise; and cannot by any a●●ments be persuaded unto it, but 〈◊〉 apt to think such remedy as b● or worse than any disease it 〈◊〉 prevent.  
So that although Exercise ma● of itself sufficient to prevent 〈◊〉 eases, yet seeing that there are many Accidents which may poss●● hinder Exercise, it cannot but●● conceived a thing profitable u● many persons, for prevention of 〈◊〉 eases, to propound some other 〈◊〉 and means which may serve in st●●● thereof.  
Not that I am willing, by 〈◊〉 means, to entice any unto a sed●tary life, but am rather desirous gratify all those with a fit and meet Succedaneum, who cannot, either by ●●son of their employment, or some ●●her accident, use Exercise.  
Here we are first to suppose, that bodily Exercise is an adequate cause ●o produce the effect of continuance ●f health: And this I should first ●ove by reason, were it not suffi●ently known unto all men by ex●erience, which is the very basis and ●●undation of reason. It being then ●anted, that moderate Exercise is ●●ay and means to preserve health, 〈◊〉 us inquire into the manner how 〈◊〉 produceth that effect. And this 〈◊〉 ●inde to be done by fermenting of ●e mass of blood. Now this fermentation of the mass of blood, is ●●anted by all Physicians, to be the ●●xt and immediate cause of health. 〈◊〉 that whatsoever hath a power in 〈◊〉 self, to put a just fermentation ●●on the mass of blood, may be a 〈◊〉 Succedaneum to be used in the ●tad of Exercise, and by consequence must needs be a proper a fit Medicament to be given for t● prevention of Diseases, or preser●tion of Health.  
But before I propound those particular Medicaments, whose natu● and property is to ferment; I sh●● discourse in general of Fermen●tion.   

CHAP. VIII. What is meant by Fermentation.  
FErmentation, is a certain moti● of the Particles of some He●rogeneous matter, whereby th● Particles become so perfectly mi● and incorporated into each other that the matter doth from the● result Homogeneous, or Simil● i. e. consisting of no other parts th● what are of like nature one to an●ther, and like unto the whole.  
As for Example: When Leave● that is, extreme sour Paste, is mixed with other sweet or insipid Paste, by ●rmentation the sour Particles ●e so incorporated with the sweet, 〈◊〉 insipid, that they do receive an ●solute and perfect allay from each ●her; the insipid parts put off their ●savouriness, and the other their sourness, insomuch that the Mass or Lump doth result of a middle ●●ture compounded of them both. Yet so perfectly compounded, that the Lump may then be denominated Homogeneous or similar, which before Fermentation was Heterogeious; because that after Fermentation, it cannot be divided into insi●d and sour parts, nor into any ●her parts or particles different from ●ch other, or different from the ●hole.  
Thus are we to understand of the fermentation of the Mass of blood; ●he Mass of blood is in itself a vari●usly-compounded and mixed body, consisting of such diversity of parts, all apt to act upon the body after different manner according to 〈◊〉 nature of each part, that were th● not all united by Fermentation, th● would quickly destroy the body Obstructing, Corroding, Exul●rating, Putrifying, etc. but bei● by Fermentation united, the visco● and thick parts are Attenuated, t● thin are incrassated, and the Ac●mony thereof much contemper● and allayed; and all other partic● so firmly embodied into those th● are of a contrary nature unto themselves, that the mass is thereby rendered of a just crasis or temperame● fit for the Nutriment of the body.  
To this end, there is given, b● the providence of Nature, even un● the very Embryon in the Womb, large Coagulum of blood, I me● the Liver, together with the formation of its parts, that whatsoever ●● ingested into the body, may by virtue of this Coagulum be fermented and so united unto the mass, that 〈◊〉 the tender parts may, by the mass 〈◊〉 blood receive no detriment, but 〈◊〉 nourished and augmented by it. ●ow that Nature hath designed the ●wer in young Children for Fer●ntation, it is evident; in that then the Liver ceaseth to do its office, that is, to ferment the blood, often times grows unto the side of child; even as the Umbilical Vein ●sing to convey nutriment into the ●dy degnerates from its former na●re, and unites itself with the muscles of the Abdomen.  
And as Nature doth at first pro●de this Coagulum for young Infants, ● doth she afterwards by degrees ●ovide for others that are adult by ●ongesting in the other side of the ●ody another Ferment or Leaven of more terrestrial substance; I mean, the Milt or Spleen, altogether as fit 〈◊〉 perform the office of Fermenta●on in others, as the Liver in young children.  
Here it will not be unworth our observation to take notice, 〈◊〉 whatsoever is received into the Ve● and Arteries, and circulated toother with the mass of blood, exce● it be united to the blood by Ferm●tation, cannot but become hurt to the body. It may either by 〈◊〉 Density and Viscosity obstruct 〈◊〉 narrow passages, or by its Acrim●corrode the tenderest parts, or 〈◊〉 by its putrefaction corrupt 〈◊〉 blood. Now here we must n● that by Concorporation with 〈◊〉 mass of blood, it's hurtful quali●● can receive no allay, except t● Concorporation be done by ●●mentation. As for example: 〈◊〉 Hony there is a certain sharp or ●●rosive part, which although it 〈◊〉 Concorporated with that o● sweet and healing part, yet is 〈◊〉 the Acrimony thereof allayed, 〈◊〉 by being Fermented with the swee● part it is thereby abated; the tr● whereof may appear by this Expe●ment. Take a pound of Honey, a● ●oyle it a little while in three Pints 〈◊〉 any water that will bear Yeast; ●●sh any sore with this liquor unworked, and you may observe it to 〈◊〉 very detersive and cleansing: ●at afterwards work the same with 〈◊〉 little Yeast, and then you shall ●●de it of another nature, not in the ●ast detersive. By Fermenting or ●orking, the sweet and sharp parts 〈◊〉 the Honey, are so firmly united to ●●ch other, that they lose their for●er nature, and produce a third, ●hich is different from either. ●ence it is also, that not only the ●arper, but the sweeter parts also of ●at liquor, by Fermentation, are ●●ayed, as may appear by its taste ●nto every Palate.   

CHAP. IX. What things perform the act of Fermentation.  
HAving in the general touched 〈◊〉 little upon fermentation, 〈◊〉 shall now recite a Catalogue of suc● things, as are endued with a facul● of fermenting, especially those th● are most signal. And these ar● Coral, Pearl, Mother of Pea●● Steel, Crabs Eyes, Egg shells, t●● Liver and Milt of all kind 〈◊〉 Animals boiled and dried; t●● Shells of Crabs and Lobsters, Cora●lina; with many others. All whi●● agree in this, that they lenify sha● humours; open obstructions; provoke the Menses; stay the bleedi●● at Nose, or elsewhere; stop, wi●● much safety, all manner of Flu●es: assuage pain; provoke Urine; p●● a good confitence upon the mass 〈◊〉 ●loud; strengthen the Spirits; alloy ●apours; exhilarate the mind; procure an Appetite; help Digesti●●●; open the Pores, and produce an ●●sensible transpiration; clear the ●kin, and make the Countenance vegete and lively.  
Now although all these things, do work all these effects in some de●ee and measure, yet seeing that experience hath found some to be more infallible and certain than o●●er some, or at least more general: shall propound that which experience hath taught to be the most general of all, and that is, Steel. And ●●eing that in this also experience hath found some uncertainty, by ●eason of its various preparations, ●nd several ways of exhibition; I ●hall above all commend one preparation, called, Sacharum Martis, or Sugar of Steel, and that to be given ●o otherwise than in Wine or Wa●er. And this Sugar of Steel, so exhibited, may be truly called, Panacea, or that universal Medicament which may in itself be sufficient, 〈◊〉 touching the Prophylactical part 〈◊〉 Physic, that is, to prevent disea●● and preserve health, as you m● read afterwards. Yet is it not to 〈◊〉 denied but that Steel hath be●● often tried, and found ineffectual 〈◊〉 the distempers of young Infant Whether it be for want of due Preparation, or that it is too strong Ferment: However, I shall not 〈◊〉 present propound this, although t●● best Preparation of Steel for tende● Infants, but offer another Medicament, yet of the same tribe which is well known by experience not only of myself, but divers others; and this is Red Coral, 〈◊〉 which also you shall read afterwards  
It is not impertinent in this plac● to show, how that grand Quae● may be resolved, viz. How is it possible, that the same individual Medicament, should be efficacious to prevent or cure several diseases o●● ●●fferent, and perhaps of contrary ●●ndes? Which thing is evident and ●ear by what is here supposed. It ●here supposed, that Fermentation ●f the mass of blood doth lenify ●●arp humours, and yet attenuate ●hose that are viscous and gross; that 〈◊〉 doth both provoke, and yet stop ●he overflowing of the Menses, and produce many other such like effects of a contrary nature. So that if any ●ne Medicament will but Ferment ●he blood, it may by the same reason produce different, yea contrary ●ffects upon the body.  
This is also to be exploded for a ●alse opinion, viz. That Steel performs contrary effects, opens obstructions, yet stops Fluxes, by a diversity of parts which it hath in itself. Whereas ●t performs these different effects only by that one individual act of Fermenting the blood, seeing also that all other things, as Coral, Pearl, Corallina, etc. which have a faculty of Fermenting, do produce the same different effects. I shall now she the use of these two Medicament first of the Coral for Children, all th● are under seven years of age; a● afterwards of the Steel for all other Men, Women, and Children, abo●● seven. But this is first to be advertised, that it is not here pretend●● how the Coral and Steel do of themselves perform the whole Act 〈◊〉 Fermentation, but only by Fermenting a little, do put the Liv● and Spleen upon their Office of Fementation, even as exercise dot● whereof these are propounded as Succedaneum; yet so, as that so●● exercise, if possible, is also to be use with them.   

CHAP. X. ●●w children's diseases may be prevented by the use of Red Coral, which Fermenteth the Mass of Blood.  
●Or prevention of Diseases in Children under seven years of ●●e, give them either the Magistery 〈◊〉 the Syrup of Coral, or else Red ●●ral prepared, twice every day for ●ree days together, once in a foresight or thereabouts. Give a child 〈◊〉 about four or five years old, five ●raines of Red Coral prepared, ●●x'd with a little conserve of Bar●●ries, from a knife's point in a morn●●g fasting, and let the child drink 〈◊〉 draught of spring-water, either sweetened with sugar, or alone, immediately after it, if it be in the summertime; but if in the Winter, ●hen a draught of white-Wine. Let him fast at least an hour, and, if can, let him exercise after it; him do the like at four in the aft●noon, and so the next day for th● days together.  
Or in stead hereof he may t● seven grains of Magistery of Co● from a knife's point, mixed with 〈◊〉 pap of an Apple after the afores● manner, drinking wine, or wat● or both mixed together, accords to the season of the year, exerci● and fasting after it as aforesaid.  
Or else he may drink half an ou● of syrup of Coral at a time, in w● or water, according to the seize twice every day for three days together, as aforesaid.  
Now although this be the w● and means to prevent such Dises only as are apt to breed within 〈◊〉 body, yet is it also a great means strengthen Nature, to resist those ●ther Pestilential diseases, as t● Measles and small Pox which co● from without; as also to enable t● body the better to encounter with ●●se diseases in case they should ●pen. For doubtless the only ●son why, when the seeds of those ●stilential diseases are sown in seve● bodies, some die, others languish ●ong time, and others speedily re●er, is this, viz. because some ●lies are of a better Crasis or Tem●ament than others. And this also ●n undeniable truth, that the Eu●sie and dyscrasy of all bodies, do ●cessarily depend upon the more ●fect or imperfect Fermentation the mass of Blood.  
And here, that not only a rational ●t also an experimental satisfaction ●y be given unto all persons whatever, concerning the efficacy of ●ral, for prevention of children's ●eases; I shall propound this following Experiment.  
Give of Red Coral twice every ●y six or seven days together, according to any of those ways beddoe mentioned, unto ten several children which have contracts some general distemper; not s● as may bear the denomination of a particular disease, but so as it m● clearly appear that they are indis●sed, and not perfectly well, as m● perhaps appear by their loss of appetite, by the more than ordina● Paleness and Wanness of their Contenance, or by other some such-● infallible signs and tokens; t●● have upon them no particular 〈◊〉 ease, but only that which Phy●ans call a general Cachexy, that an immediate inclination or disp●tion unto all manner of diseases 〈◊〉 say, give unto ten such Child● twice every day, for six or se● days together, of this Red Cor● according to any of those ways b●fore mentioned, and you shall ●●serve (except somewhat extraordinary prevent it) that scarce one these ten shall continue, to the spa● of those six or seven days, unrestored unto its perfect health.  
After that, make choice of ten ●ore Cachectically distempered children, but give the Coral only 〈◊〉 five; and then after a few day's 〈◊〉 shall observe the difference, and ●t no small difference, between ●hose unto whom you gave the Co●l, and the other. I appeal with ●uch confidence unto any man's ex●ience, because I know it already my own experience.  
I know by experience that Red ●oral cures the Cachectical distem●rs of children, as infallibly as Steel ●res the Green Sickness; and I cannot persuade myself but that ●he effect is performed upon this ●●count. Those Cachectical distem●rs proceed from an imperfect Fermentation: Coral Ferments; where●e by taking away the cause, it removeth the effect also, according to ●at old, worn, yet true Axiom, ●blat â causâ, tollitur effectus.   

CHAP. XI. How the Diseases of those pers● which are above seven years' 〈◊〉 may be prevented by the use of St●●  
AS Coral for young Infants, Steel for all others above ●ven years old is, if rightly made of, a great preventer of Diseases, 〈◊〉 preserver of health. And amo●● those preparations that are as 〈◊〉 extant, there is none compara● unto that which goes under the 〈◊〉 nomination of Sacharum Martis, Sugar of Steel. The use whereof to the Prophylactical or Preservat● part of Physic, is as followeth.  
Let any healthful person drink grains of Sugar of Steel in a dra●●● of spring-water in the mor●● fasting, exercising and fasting at 〈◊〉 lest an hour after it. Let him her do the like also at four in the ●ternoon, and so the next day, and 〈◊〉 next after that, for five or six ●●yes together. And after a month's permission, the same course is to be ●ated.  
Note, this water is to be used in ●●e Summertime, but in the Win●●r the Sugar of Steel is to be dissolve in white-wine in stead of water; spring time and in Autumn, water 〈◊〉 wine may be mingled together.  
●or a Boy of eight, ten, or twelve ●●s old, six, seven or eight grains 〈◊〉 be sufficient.  
Now for a certain trial or proof 〈◊〉 of this Sacharum Martis, or ●ar of Steel; I offer the same ●●ner of experiment which I did ●ncerning the Coral for young ●ildren, that it may clearly ap●● unto all persons whatsoever, 〈◊〉 only upon a rational, but also ●n an experimental account, that ●ar of Steel is a True and Legi●ate means to be used by any of ●ove seven years old, for prevention of diseases, or preservation health.  
Give unto several persons wh● are Cachectically distempered, t● every day, for the space of te● twelve days, of Sugar of Steel, 'cording to the manner above motioned; and if within that space time, all or most of them shall be stored unto their perfect health cannot be denied, but that th● foresaid means must needs be effe●al for the intent and purpose aforesaid.  
Yet I think we need not go sc● as this for a trial; For let any pe● whatsoever, of the most abson and perfect health that may be, 〈◊〉 of this Sugar of Steel for ten twelve days together, after 〈◊〉 manner aforesaid; and ten to 〈◊〉 within that short space of ti● there will appear at the least so outward signs of health 〈◊〉 strength more than formerly. I ten to one, but that his countena●● be somewhat more vegete 〈◊〉 lively, and that he will have ●mewhat a quicker and sharper ap●ite to his meat.  
〈◊〉 have now done with the Pro●lactical, or Preservative part of ●●sick, wherein I have, I hope, ●en satisfaction to all those whom ●son will satisfy, concerning the ●●acy of Coral and Steel for pre●tion of diseases. It remains in the ●t place, that I treat of the The●eutical or Curative part.   

CHAP. XII. ●at the things not natural, are necessarily to be observed together with the use of Coral and Steel, for ●he cure of diseases.  
WHereas it is not only a thing more dfficult to cure diseases ●e contracted, than beforehand prevent them; but also a matter of greater consequence, because diseases unprevented, terminate one in sickness, uncured in death: 〈◊〉 behooveth every Physician to 〈◊〉 so careful of his Patients recover from any disease, that he neglect 〈◊〉 rational and probable means t● may serve for that intent 〈◊〉 purpose.  
Hence is it, that although 〈◊〉 chief aim is to divulge the efficacy these two medicaments for 〈◊〉 curing of diseases, which indeed 〈◊〉 chief to be considered; yet shal● not be silent as touching any oth● additaments, or helps which may subservient unto them.  
Wherefore although for g● reasons I have rejected all th● things which Physicians call not ●●tural, for prevention of diseases, ●●cept Exercise; yet for the cure diseases, it will be necessary to ●●brace them so far forth as reason 〈◊〉 admit. As first, for matter of D● it is requisite that it be, for quant● ●ry little or spare; and for quality, ●h as may be easily digested, in ●ose diseases where Nature is chief ●ncerned in the conquering and ●posing of some Morbific matter, 〈◊〉 she be called away à Pepasmo ad ●psin, from her encounter with the ●sease, unto the digestion of meat. ●or is the Palate in sickness to be ●garded, because she is then vi●ted and corrupted, disliking that ●ich is wholesome and profitable, ●d relishing other things which are ●ngerous and destructive to the ●dy. The Diet is also to be ap●opriated unto the disease, accord●g to the common experience of all ●ysicians. As for example: flesh-●at is to be denied, or at least, not freely granted in Fevers, because ●perience teacheth that the Chyle Juice extracted by the Chemistry Nature from thence, and trans●ted into the Veins and Arteries, most obnoxious unto putrefacti●. Anchovies, Mustard, French-wine, and such like things of muc● acrimony, are by no means to b● given to those that have inward Ulcers in their Bladder, Kidneys, o● elsewhere, because they are apt ● excoriate and fret, and so to increase and enrage the distemper. Th● Diet which is Analeptical or Reston●tive, is to be given to Consumpti● persons: and so for other diseases there is scarce any distemper whatsoever which may not in some measure be abated, by a due observation of Diet.  
And as Diet, so Air also in t● cure of diseases is somewhat to 〈◊〉 regarded: as in those disease where transpiration or sweeting 〈◊〉 required, care is to be taken, that t● ambient Air be as warm as may b● that so the Pores may be kept op● & not closed too suddenly, where● the Morbific matter, once attenuated and enraged, may not be lock up in the body to the exasperation and increase of the disease, b● gradually breathed out and spent, to ●e recovery of health.  
So for sleep: Care is to be taken ●at in Fevers and suchlike Di●empers which spend the spirits, ●at it be moderately procured to afresh the body, and strengthen ●ature to encounter with the disease. Neither are the affections vio●ntly to be moved, and the mind ●scomposed in sick and weak per●ns, by relating any thing that is ●npleasant, or less desirable to be ●eard. For experience teacheth, ●at a very small commotion of the ●inde, hath great influence upon a ●ck and weak body; whereas great doubles and discontents do very atle or no hurt unto the bodies of ●ose persons that are in perfect ●ealth.  
Having premised this in the gene●l, I shall now descend to particu●rs, and discourse first of the Effi●cy of Steel in the cure of Diseases, than afterwards Analogically to●● upon the Coral also.  
Some Diseases there are whi● Steel doth both prevent and cure, ● the Green Sickness, the Spleen, Scurvy, Jaundice, Mother, Go●● Consumption, Ague, Stone, Flu●● Dropsy, Strangury.  
Although it doth prevent, y●● doth it scarcely cure continual Fevers, and the Epilepsy, or falli● Sickness. And although it do● prevent, yet doth it not cure 〈◊〉 Apoplexy. As to the French d●ease, it doth neither prevent nor cu●● it; yet is it useful for this, and 〈◊〉 others, as shall appear in the sequel● my discourse. I shall treat of the Distempers in the same order as have propounded them; as first 〈◊〉 the Green Sickness, then of th● Spleen, Scurvy, Jaundice, etc. a● they are here above described.   

CHAP. XIII. ●f the Cure of the Green Sickness, by the use of Steel.  
THe Green Sickness is a distemper peculiar unto young Maids, ●hich renders them listless and loath 〈◊〉 stir; which makes them in their ●●e or countenance squalid, and less handsome, of a pale and greenish ●olour, from whence it hath the denomination of Green Sickness.  
It proceeds from the defect of fermentation of the Mass of blood, ●●e Liver and Spleen not performing ●heir office according to the intent ●f Nature.  
It is cured only by the use of ●ugar of Steel. Give the Patient ●wenty grains of Sugar of Steel in a ●raught of spring-water in the morn●ng fasting, and as much at four● in ●he afternoon, for the space of ten or twelve days together, and 〈◊〉 her every time exercise very w●● after it. And in case her distemp●● be such that she have not her Mens●● let her continue taking the san● quantity at the least twice so long● and let a vein be opened in the le● foot, to the evacuation of eight o● nine ounces.  
It is here worth our observation to take notice how this Sugar o● Steel drank in a draught of spring-water twice every day, with exercis● after it for a fornights' space, doth beautify and enliven the countenance, not only of those who have the Green Sickness, but of other● also, insomuch that there are scarce any who look so well, but by taking of it will appear in their countenance much better, livelier and clearer than before. A thing which may in itself signify the wholesomeness of the Medicament.  
Certainly were many of our Gallants in this City advertised of this, ●●ey would lay by all their Un●ents, Paints, and Washeses, which ●n at the best afford them but an artificial hue, and would betake ●emselves wholly unto this Sugar 〈◊〉 Steel, whereby, besides the benefit and advantage of health, they ●ight gain a clear, lively, becoming, amiable, natural complexion.   

CHAP. XIV. ●ow Steel conduceth to the cure of the Spleen.  
THere are several Distempers arising from the Spleen. Know ●herefore for distinctions sake, That ●y the disease called the Spleen, I ●nderstand both the swelling of the spleen, which is accompanied with ●iolent pain, by reason of the va●ours distending those Nervous Fi●res which are in the body of the Milt or Spleen, as also those Hypochondriac Vapours which are fro● thence dispersed, which fuming 〈◊〉 into the Head disturb and discompose the Brain, which suffocate a● almost stop the breath▪ beside extreme pain, and some other troublesome and pernicious symptoms.  

A Case.  
A Gentleman of about twe●● eight years of Age, having been 〈◊〉 fits for the space of four or five yea● much troubled with violent pain 〈◊〉 his Spleen, was thus cured.  
He took ten grains of Sugar Steel in a draught of spring-wa●● twice every day for the space of 〈◊〉 days, walking very easily after (for he durst not move violently 〈◊〉 any time for fear of his pain) a● after ten day's intermission, he to● it other ten days after the sa● manner; and so he did by cour● every other ten days, for the spa● 〈◊〉 half a year. In the mean time ●hen he was by fits taken violently ●●th his pain, he had present ease by ●●inking a draught of raw White-wine bloud-warm, together with an ●ince of Syrup of Red Poppies. ●ut his pain, by taking of Steel grew ●ss and less every fit, insomuch that 〈◊〉 two months' time it was almost wholly abated: so that he needed not ●he White wine and Syrup of Poppy at the furthest above ten weeks, ●nd that at the latter end not above ●nce in a fortnight, although at first ●e was constrained to take it once in ●our or five days.   

Another Case.  
A Gentlewoman, a Widow of ●hirty seven years of age, bein● ve●y much oppressed with Hypochondriac vapours, was thus cured in the ●pace of ten days. She drank twice ●very day twenty grains of Sugar of Steel in Spring-water; and in that ten days she bled twice in the foot● to the quantity of about nine or te● ounces. She took also for the first three nights, a Bolus consisting of half a dram of Venice-Treacle, hal● a dram of Conserve of Red Roses, and a grain of Opium.  
A Boy of about fifteen or sixteen years old, was cured of the swelling and pain of his Spleen, by only Sugar of Steel; drinking ten grains at a time, in a draught of Spring-water twice every day for three weeks together.  
A Maidservant of twenty three years of age, about the fall of the Leaf or Autumn, was much troubled with hypocondriac vapours every afternoon for three weeks or 〈◊〉 month together: she was also taken after the same manner the Spring after. And having tried many things to no purpose, was at length cured by Sugar of Steel drank i● Spring-water, twelve grains at 〈◊〉 time twice every day for a fortnight ●fterwards, fearing the return of ●er distemper, and thinking with her ●elf that her cure might be wrought ●s well by means of the water as the Steel: applied herself wholly unto ●he drinking of nothing else but water, both at her meals and all other times. This she continued for a year and half, in which time ●he had not the least touch of her distemper. But afterwards returning unto her drinking of Beer as formerly, she perceived a recidivation of her disease; so after that by drinking only water again was ●cured.  
This I relate to gratify all those that are inclined unto hypocondriac vapours; which distemper may as well as any that I know, be called, Opprobrium Medicorum, the shame of Physicians; because so many labouring of this disease have come out of the hands of very able Physicians uncured. Yet do I verily persuade myself that it might be cured in any person whatsoever, by the only use of Sugar of Steel and Water, by drinking Water continually upon all occasions, and Sugar of Steel in it at some times.    

CHAP. XV. How Steel may be used for the cure of the Scurvy.  
THe Scurvy is a disease proceeding from the putrefaction of the blood, which putrefaction hath its original from the defect of Fermentation. For those particles in the mass of blood, which are not by Fermentation embodied with the rest, must needs act their particular parts upon the body; they must needs either excoriate, obstruct, or putrify, etc. according to their different qualities. From whence it is an easy thing to conceive, how a diversity of diseases may be produced in humane bodies, from one and ●he same original, viz. from an imperfect Fermentation of the mass of blood.  
The symptoms of that disease which is called the Scurvy, are pains in several parts of the body, especially in the Calves of the Legs and Thighs; and sometimes Spots also in several parts, especially in the Legs and Thighs. A weariness and loathness to stir. An itching in the Gums, and looseness of the Teeth.  
Let the Patient drink twenty Grains of Sugar of Steel in the morning fasting in a draught of White-Wine, exercising very well after it; and as much at Four in the Afternoon after the same manner, fo● the space of Six or Seven Days. After that, let him sweat after this manner following.  
In a Morning fasting, after he hath made himself as hot as he can with good store of , and by putting his Head into the Bed, give him the Liquor of Forty small Oysters wherein Twenty Oysters have bee● boiled, as hot as he shall be able to drink it. And so let him Sweat very well after it, drinking a draught o● clear White-Wine Posset-drink very hot, now and then, during the time of his sweeting. After this, if occasion be, he may repeat his taking of Sugar of Steel, after the manner above mentioned, and so after that sweat again as formerly.   

CHAP. XVI. Of the use of Steel, in the Cure of the Jaundice.  
THe Jaundice is a Disease well known by the Yellowness of the Skin, which is commonly first discovered in the Eyes, which oftentimes produceth Pain and Dizziness in the Head, want of Appetite and Digestion, with some other symptoms. 〈◊〉 is caused by a thick and viscous humour, which obstructeth that passage, ●hich is called, Meatus choledo●us, the Channel or Passage through ●hich the Yellow Choler, contained in the Vesicula fellea, or Bladder ●f the Gall, according to the course ●f Nature is transmitted from ●ence into the Intestines. For when ●at passage is obstructed, the Yellow Choler is thrown out into the ●ass of blood, by the same way that 〈◊〉 was first conveyed into the Bladder of the Gall; even as when the pylorus, or lower Orifice of the stomach is stopped, that which was in●ested, is oftentimes thrown up by vomiting the contrary way. Now ●hen the Yellow Choler is thrown ●p out of the Bladder of the Gall ●to the mass of blood, and Nature attending always, when she is able, ●o purge and cleanse the blood of its ●xrements by Urine and Sweat; ●ence it is, that both the Urine ●●d Skin do receive the yellowness and tincture of the Choler  
To say nothing, how this visco●● humour proceeds from the want o● Fermentation, the cure is chief performed by Steel, although perhaps sometimes there may be occ●sion to make use of somewhat else, 〈◊〉 subservient unto it.  
There is that which is called th● Black, as well as the Yellow Jaun●clise, which proceeds from som● matter thrown out from the Splee● into the mass of blood, even as th● Yellow doth from some of the matter contained in the Gall.  
The Black Jaundice is cured b● the only use of Steel in manner following. Give the Patient Twenty Grains of Suga● of Steel, in a draugh● of White Wine in the Morning Fasting, and as much after the sam● manner at Four in the Afternoon for ten days together.  
Let the like be done also for th● Yellow Jaundice, except that th● White-Wine, wherein the Steel is t● 〈◊〉 dissolved, is first to be coloured ●th Saffron.  
Or else, let the Patient take the ●antity of a Nutmeg of this Electu●y following from a Knives point ●ery Morning Fasting, drinking Ten ●rains of Sugar of Steel in a draught 〈◊〉 White Wine after it, and as much Four in the Afternoon, after the ●me manner for Ten or Twelve ●●yes together.  

The Electuary.  
Take of Cardamom-seed Long●epper and Turmerick, all finely powdered, of each a Dram. Saffron powdered, half a Dram. Conserve of ●osemary-Flowers, two Ounces; ●ith as much Syrup of the Five opening R●●●●s as is sufficient: Make ●hereof an Electuary to be taken as ●bove mentioned.    

CHAP. XVII. How Steel conduceth to the Cure 〈◊〉 the Mother.  
THe Mother is a distemper peculiar unto Women, whos● symptoms are hindrance o● the exercise of the Animal Faculties by Fits or Paroxysmes; as also 〈◊〉 hindrance of Respiration: which symptoms are caused by Vapours ascending from the Mother, o● Womb. The Vapours ascending to the Brain, do hinder the exercis● of the Animal Faculties, and withal elevating and raising the Matrix o● Womb, so that there is a compression made upon the Diaphragma; they do also hinder Respiration.  
It is a distemper easilier prevented than cured; and easilier cured at the first, than afterwards, when the ●apours have for some time been ●bituated to ascend. For than up●● every small commotion or distur●nce of the mind, they are apt to ●●end and cause the Paroxysm; ●is is too well known by experience, ●hich verifies that Maxim, Habits est qualitas difficulter mobilis.  
Therefore by how much the longer ●e distemper hath continued, so ●uch the longer time must the Steel ●e used. Give the Patient 15 grains ●f Sugar of Steel in a draught of spring-water every morning fasting, ●nd as much at four in the afternoon ●●ter the same manner, for twenty ●ayes together: she may take it a ●nger time proportionably to the continuance of the disease; or else ●termit twenty days, and then ●●ke it other twenty.  
Here we may note that this Medicament is the most apposite and fit ●r this disease, of any that can be ●iven, both in respect of the Water, ●nd of the Steel. Water hath a natural propriety to allay vapour and Steel hath a faculty of procuri● that which is called Deorsum t●dentia, a motion downwards; bo● which are required in the cure 〈◊〉 this disease. Hence it is that 〈◊〉 only water, but every thing e● that is apt to allay vapours, is kno●● by experience to be good for th● distemper; and on the contrary things apt to raise vapours to b● hurtful. So are all other things besides Steel which are apt to make motion downward, known by experience to be good; as the taking Tobacco, the burning of Feather● the smoke of Assa-Foetida, and 〈◊〉 other stinking smells; the fume 〈◊〉 Benjamin, Storax, and Frankincense, received up into the body, a● suck-like.  
How the Steel performs this effe● of making a motion downward whether it be by its Elementary form, or some other Specific quality, and by what means the wat● ●oth produce its effect of allaying ●pours, it is not in this place to ●ntrovert.   

CHAP. XVIII. Of the Cure of the Gout by Steel.  
THe Gout is an extreme pain in the joints, caused by an humour settling there and sometimes ●ntrefying, whereby the Tendons, ●hich are tightly sensible, are ●stended.  
The matter settling and residing in ●e joints, is the Seminifick or Sper●atick part of the blood: hence it is ●at Eunuches, Women, and those that ●re under Age, are seldom or never doubled with this disease.  

A Case.  
A Gentleman, an Ancient Bachelor of about forty years of age, was very much and often tormente● with the Gout; who after the try● of many things to no purpose, w● at length thus cured. He drank t● grains of Sugar of Steel in a draugh● of Spring-water every morning fa●ing, and as much at four in the afternoon for a month together; an● applied to the part affected the pu● of a roasted Turnip as hot as he wa● able to bear it. After the mon●● was expired, he left taking the Stee● but continued the Water, drinking it constantly at his meals and all other times; this he did for the space 〈◊〉 two years, during which time 〈◊〉 had little or no pain in his joints only now and then some sma● touches, which he could cure himself immediately, by applying the pu● of a roasted Turnip mixed with 〈◊〉 little Saffron to the part affected▪ After the two years, he married 〈◊〉 young Gentlewoman in whom b● much delighted, and then notwithstanding his return unto drinking 〈◊〉 ●●er and sometimes Wine, as former's he continued well.  
Another Gentleman, a Bachelor 〈◊〉 about thirty years of Age, was ●red only by drinking Water. ●here note, that Water hath of it ●f a Specific faculty of curing the rout; and on the contrary, Wine is 〈◊〉 to Exasperate that disease. So ●at the Reader is here to be adversed, that although for prevention 〈◊〉 Diseases, I have propounded ●gar of Steel to be drank, in the ●mmer-time in Water, and in the ●inter in White-wine, in the Spring ●d Autumn in Water mixed with ●ine; yet for prevention of the rout, those persons who suspect or ●r it, must drink it any time of the ●ar in water. I counsel them also 〈◊〉 drink Wine very seldom or ne●r, and to use as much exercise as ●ay be.    

CHAP. XIX. Of the use of Steel in the Cure of Consumption.  
A Consumption is truly and properly an Ulcer in the Lung● which by putrifying and spreadi● doth waste and consume the Lungs although generally it is taken for a● kind of Languishing and Consuming of the Body. It is of all disease considering the time that the Phy●tian hath to turn himself in, the m● difficult to be cured; therefore th● greater care is to be taken in th● cure of this disease, that nothing 〈◊〉 omitted which may in any sort contribute to the benefit of the P●tient.  
It is bred of a putrid, and also o● sharp humour in the Mass of blout (which humours continue such 〈◊〉 want of Fermentation) therefore ●l things that do add either to Acrimony or Putrefaction must needs be hurtful, Et vice versâ.  
For the cure of this disease, there 〈◊〉 first a regard to be had unto those ●hings which are called not natural, 〈◊〉 Air, Diet, Sleep, the Passions of ●he Mind, Exercise. As for Air; although, considered in itself in re●ect of the Climate, it is not easily ●o be distinguished whether it be ●etter or worse for the preservation ●f health, seeing that many of all constitutions are very healthful in ●ny manner of Air; yet certain it is ●hat the Air may be bettered by Art, ●nd corrupted by accident; witness ●hat sad accident which many years' ●nce, happened unto one Mr. Smith ●nd his Family. Mr. Smith, the town-clerk of Grantham, together ●ith his Wife, Maidservant and too Children, were all in one night bereft of life, by reason of the ●r vitiated through vapours arising ●om Charcoal; removing unto a new house to dwell, having its wal● new limed and not throughly dried to correct the dampness of the ai● they placed a Pan of Charcoal 〈◊〉 the Room, and having close shut th● Doors, they went all to bed, and i● the morning were found all dead.  
Now seeing that the Air may b● accident be so corrupted, as in 〈◊〉 short a time to make so great a● alteration, as from health to death much more may it be so vitiated a● in continuance of time, in Chronical and Languishing diseases, in som● measure to increase the disease. Tha● which either in the Air or aught else is most apt to increase that diseas● which is truly and properly called Consumption, is either Acrimony or else Putrefaction. Acrimony cannot subsist in the Air, being 〈◊〉 thing much different from its Elementary form. For we are to understand by Acrimony, matter consisting of Angular Atoms; but 〈◊〉 Air, matter consisting of Spheric● Atoms.  
It remains then that whatsoever 〈◊〉 the Air may be hurtful unto this ●sease, must needs be Putrefaction: ●nd indeed the Air is as much Obnoxious unto Putrefaction, as any ●ther thing whatsoever. Now ●hereas Air may be either more or ●ess putrid, it must be either better ●r worse for this disease.  
We are therefore to inquire into ●he quality of the Air, in this respect, and consider what Air is more ●r less putrid. And this experience ●ath taught, that in populous places, ●n great Cities which are continually ●equented with a great multitude ●f people, the Air is most of all putrid; 'tis probable it becomes so ●y reason of the breaths of many people putrifying, or else from that putrid matter which is continually ●hrown out of their bodies by Transpiration, either sensible or insensible.  
That the Air is most putrid in populous places, it can be Demonstrated by no better an experiment, than by the corruption of any kind of flesh. The Butchers all know by experience, that any kind of flesh-meat, is sooner putrified and corrupted in the City, than in the● Country; which must needs be through the putrefaction of the Air. It is therefore expedient for all Consumptive persons, who dwell in the City, or any close place amongst many people, to remove into a more open Air, that the cure of their disease be not hindered by reason of the Air.  
The next thing to be regarded is Diet, which is subject not only to putrefaction, but also unto Acrimony or sharpness, whereby such a Juice may be conveyed into the mass of blood, as may by fretting, and corroding, exulcerate the Lungs. Wherefore Salt, although it resist putrefaction, yet because it is apt to corrode, is hurtful; and so are all things sharp or sour. So is Stale-Beer, and Ale, if it lie long in the ●omack, because by that means it is oftentimes made sour. But if Ale, ●hich hath as yet contracted no ●wreness, be drank very Warm, so ●at it may immediately be conveyed into the Veins and Arteries, by ●eason of its lenifying quality, it must ●eeds be profitable. The much use ●f Bread is also very wholesome, by ●eason, not only of its lenifying qua●ty, but also in that it is apt to re●st putrefaction. Flesh-meat is hurtful, especially in the City, because there it doth soon putrefy. ●dence it is, that the City-Air is to be ●voided, not only in respect of it ●elf, but also in regard of the Diet which it is too apt to corrupt.  
As for Sleep; it is also in this disease moderately to be procured: Not only because it doth recruit the spirits, but also in that it doth retund the sharpness of humours, and stop the motion of the Catarrh, ●or descent of Rheum upon the Lungs. Hence it is, that experience also teacheth that those things whic● procure sleep, if discreetly used, an● in this disease beneficial; as Diacodium, and Opium in Pil. è Styrac● and in Pil. de Cynoglosso.  
And so for the Passions of th● mind, the Patient is in this diseas● to be pleased as much as may be; because by inward discontent, the putrid matter is locked up in the breast, which Nature always intends to expel, as much as she is able, by transpiration.  
For this end is Exercise also, if possibly it may, moderately to be● used. Exercise is in itself, the best Diaphoretic, or incentive to transpiration: and certain it is, that Nature always intends by transpiration to clear the mass of blood of its putrefaction. Hence it is that the matter breathed out from many bodies by sensible sweat, is so Fetid or stinking.  
Having premised thus much, I ●m now to show the efficacy of Steel ●or the cure of this Disease. Herein ● shall consider those two cause of ●his Disease, viz. Acrimony and putrefaction of the mass of blood, part or severally; and first of Acrimony.  
That sharpness of humours, fretting and corroding the Lungs, is ●ome cause of this distemper, it may sufficiently appear by those things which do cure, or at least, palliate the disease; things which are Naturally apt to retund, lenify, or assuage Acrimony. Such are mild Ale, New-Milk sweetened with Sugar; the Liquor of Snails made into a Syrup, with White-Sugar-Candy, and Snails boiled in Milk.  
Now that Steel is also endued with a faculty of lenifying sharp humours, it may appear by this following experiment. Put an Ounce or two of the filings of Steel into a Glass-Bottle, unto which put a Pint of very sharp Vinegar, or Juice of Lemons: let them be together two days, and now and then shaked up; and in that time, the Vinegar o● Juice of Lemons shall have put of all its sourness, and shall become in a manner insipid.  
That some putrid matter in the mass of blood, is a cause of this distemper, may also appear by other things resisting putrefaction, which palliate the disease; as the Powder of Red-Rose Leaves, and the Juice of Turnips baked, etc. And that Steel doth resist putrefaction, may appear by this, in that the Water wherein Sugar of Steel is put will not putrefy.  
To say nothing of the Sanative or healing faculty of Steel, as also of its Fermenting power, by reason of both; which reason will also admit, that Steel may be a legitimate Medicament for this disease, I appeal unto the experience of those persons, that shall rightly use it.  

A Case.  
A Minister in the City of about ●hirty five years of age, was thus ●ured. He had first an Issue made in ●is lest Arm, than went into the Country, and for the first ten days drank ten grains of Sugar of Steel, ●n a draught of Spring-water every morning fasting, and as much at ●our in the afternoon, exercising very well after it; his exercise was only walking, yet by that he heated himself very well, being very well clothed, and put himself into a breathing sweat; the place where ●he walked, was upon plow'd ground newly broken up. After the first ●en days leaving his Steel, he applied himself to the drinking of new Milk and Sugar morning and evening, which he continued for the space of a fortnight; then he repeated his taking of Steel as before, and after that Milk, very warm from the Cow as formerly. In the mean● time he combed his head very well every morning with a small toothed comb, and once in two or three days had the ends of his hair cut, and provoked himself to sneeze every other day with a little white Hellebore grated, and snuffed up into his nostrils.  
As for his Diet, he would eat good store of Bread with whatsoever else he did eat, and oftentimes Bread alone; and besides his taking now and then some of the Juice of baked Turnips with Sugar, he would oftentimes make a meal of buttered Turnips. His drink was small Ale, which he always drank very warm, both at his meals and other times: after all his meals he sat still about half an hour, than walked at the least an hour upon plow'd ground newly broken up: the Chamber where he lay had its Casements open all the day, and in the evening before he went into it, 〈◊〉 was well warmed with a good fire, ●nd perfumed with Benjamin, Storax ●nd Frankincense: every night so ●oon as he was in his bed, he took ●om a kisses point the quantity of a Nutmeg of Conserve of Red Roses. By this means he was not only cu●ed of his Consumption, but afterwards became more Corpulent and Fat than ever he was before.  
In this case is represented only the Practical part; I shall now by Commenting upon the several particulars show the Rationality of this Practice. And first, to say something of the person, the Patient was a Minister. We must know, that of all men in the City, Ministers are most Obnoxious unto Consumptions, in that their Lungs are most of all strained, and their bodies least exercised, besides the weakening of their Brain by continual study; Of which afterwards. Orange and Oyster-women, and suchlike, which cry about the streets, although they strain their Lungs, yet they have this advantage, that they are necessitated to exercise, whereby they receive the greater benefit of Transpiration. Doubtless the reason why Consumptive persons, if they pass the midst of May, do commonly scape for that year; is only because they have then the greater benefit of Transpiration. For this reason the Patient used exercise, and kept himself very warm with .  
The reason why after ten days he left his Steel and drank Milk, is this, viz. Because, although Steel doth both Lenify sharp humours, resist Putrefaction, Ferment, and Heal, yet is it not Nutritive; and the reason why after a fortnight's use of Milk, he left that also to return unto his Steel, is this, viz. Because, although Milk doth both Lenify sharp humours and also nourish, yet doth it in continuance of time, Obstruct, and so by accident produce Acrimony or sharpness of humours; For whensoever the Pylorus or lower Orifice of the Stomach is obstructed, ●o that the liquid matter contained ●o the Stomach cannot in some convenient time pass away; it must ●eeds by the heat of the Ambient ●arts contract an Acidity or sourness; even as if the mildest Ale be ●lose stopped in any Vessel, and be set ●n some warm place, it will in a ●hort time be converted into Ale●gar.  
The reason why he smoked his Room with Benjamin, Storax, and Frankincense, is upon the same account that he changed the City for the Country-air. Some skilful Surgeons there are, who by suming ●int with Benjamin, Storax, Olibanum, Frankincense, Mastic, etc. can dry up old Ulcers of long continuance; It is therefore very rational to impregnate the Air with the sum of such things as are healing, and drying, for an Ulcer in the Lungs, seeing also that Air hath so great an Affinity with the Lungs that Experience hath taught how much it doth conduce to the recovery of Consumptive persons to change the Air.  
Nor is it without reason th●● when he walked, he made choice o● ground newly broken up, because one cause of his disease was Putrefaction. Now Experience teacheth that the Earth doth very much resist Putrefaction, or rather prey upon putrid matter, especially those foil● that are hungry and barren.  
The reason why he had so much regard to the combing of his Head, Neezing, and cutting off his Hair was for the strengthening of hi● Brain. For this we must know, tha● the humours of the Body which are inclined to Putrefaction, passing through the Brain (which they are forced to do by the Circulation o● the blood) do there soon putrify when the Brain through weakness hath already contracted some Putrefaction. It is the nature of all purid matter, by corrupting and purefying, to convert all it toucheth ●nto its own nature. And the Brain ●f all the parts in the body, is the ●ost subject unto putrefaction. ●dence it is, that Nature hath prepared for it a fit Emunctory, viz. the Nose, for the purging of its Excrements; which if stopped, so that the excrements of the Brain cannot ●ass, Imposthumes are bred in one ●art or other, within the Capacity of ●he head.  
It is well worth our observation ●o take notice, that all those, who ●y any accident do weaken their Brain, are the most of all subject to Consumptions. Whether the Brain ●e weakened by Fumes and Vapours ●om Strong Beer and Wine, or by Cuts or Blows upon the Head, ●r else by much Study, 'tis all the ●me.    

CHAP. XX. How all manner of Agues may be effectually cured by the use of Steel.  
Fevers are usually distinguished into putrid and Pestilential, and putrid Fevers into continual and intermitting. An intermitting putrid Fever, is that which we call in English, an Ague. To say nothing of the several kinds of Agues, passing under several denominations; as Quotidian, Tertian, Quartain, Double Tertian, etc. it will be sufficient to show the Quiddity, or nature of an Ague in general, from its cause and symptoms, by which means also the particularities and differences may be easily discerned.  
Besides, sometimes illness at the Stomach, and Vomiting, Thirstiness, pain in the Head, and in the Back and other parts; the common symptoms of an Ague, are first Cold, ●en afterwards Burning, which are ●used by some Particles of the mass 〈◊〉 blood, at that time actually pu●efying.  
What Fermentation is, I have already described in the Eighth Chapter. Now we must know, that Putrefaction, I mean the Act of Putre●ing, is to be conceived, in some sort, contrary unto the Act of Fermen●ng. It is Fermentation reversed, ●●z. a resolution of some Homogeneous, matter into particles of a different nature: Even as when a well-governed Commonwealth doth dissolve and break into an Anarchy. Whereas Fermentation and Putre●ction do agree in one common ●enus, viz. Motion; they produce ●●e common effect, viz. Heat, ●hich is a natural product of all and very kind of Motion. But as the ●otion of either is very much ●fferent and distinct from each other, so is the Heat also resulting from either divers. The result o● Fermentation is a Natural, but o● Putrefaction a Preternatural Hea● Now whereas the Act of Putrefying is a contrary Motion unto that o● Fermenting, it cannot be that the● both can subsist together in the mas● of blood, after an intense manne● at the same time: According to that common Maxim, Duo contraria non possunt simul esse in eodem subjectio. Hence it is, that before there can be an intense Act of Putrefying, there must needs be a cessation of the Act of Fermenting. So tha● as the motion of Putrefying, doth beget a Preternatural Heat in the body, which is called the Burning or Hot Fit; even so, the cessation of the Motion of Fermenting, must needs before that, produce another Fit as Gold as that is Hot.  
The cause of this distemper i● commonly both inward and outward: the inward cause is either some putrid matter gradually collected, or else a disposition of some particles in the mass of blood to purefie. The outward cause is commonly cold, preventing Transpiration, and so by consequence hindering, or at least retarding Fermentation. For by one individual act of fermentation, we are to suppose ●hat all the Offices of Nature are performed, amongst the which, this ●s not the least, viz. That there is produced continually either a sensible ●r insensible Transpiration. Now ●s in the motion of a Clock or En●●in where several Wheels move from ●ne and the same Original cause, the irresistible stopping of one Wheel doth hinder the first cause from acting; So is it with the Clockwork ●f Nature in all humane bodies: The cessation of any one Office of Nature, which although it have its dependence upon Fermentation, yet ●ay it be a means to hinder or at ●east retard it.  
According as either the put●● matter collected is more or less, 〈◊〉 the disposition of some Particles 〈◊〉 the mass of blood to putrefy 〈◊〉 greater or less, a stronger or weak● outward cause, may give an occa●on to this distemper. An inwar● cause without some outward, do● seldom produce this disease; b● oftentimes a strong outward caus● when there is no inward cause at al● doth produce it; As many people who have no putrid matter, nor an● disposition in the humours of the● bodies to putrefaction, only tha● which they call, Potentia Naturali● a Natural power which all men hav● by some strong outward cause, a cold baths or suchlike, do get Ague● And such Agues so contracted, 〈◊〉 they continue long, are altogether 〈◊〉 dangerous as others.  
For such is the nature of an Agu● that it doth of itself produce Morbific matter for other diseases, 〈◊〉 though perhaps when it is first beg●● 〈◊〉 may have no Morbific matter of ●s own. An Ague is an habit, and ●ach fit thereof an act of putrefy●g; so that putrefaction or putrid ●atter in the mass of blood, is the product of all Agues, which, if af●er every fit it be not vented by sweated and Urine, must continue in ●he body as Morbific matter for ●ome other distempers, whether that ague was at the first chief produced ●y an Internal or External cause.  
The way and means to cure this ●isease, is to strengthen the habit of fermenting, and to weaken the ha●it of putrefying in the body of the ●atient; both which may be effectually performed by the use of steel.  
Give the Patient twenty grains of ●ugar of Steel in a draught of Spring-water every morning fasting, ●nd as much at four in the afternoon, exercising very well after it, for ten ●r twelve days together; and if in ●hat time his Ague be not gone, endeavour to prevent in him th● cessation of Fermentation, by gi●ving him two drams of Sugar o● Steel at once, in a draught of posset drink two or three hours before h●● cold fit: this perhaps may make hi● vomit once or twice, however i● doth usually continue the habit 〈◊〉 Fermentation, and by consequenc● prevent the cold fit, which is cause● by the cessation of Fermentation and so cure his Ague: for experience teacheth, that whensoever th● cold fit is prevented, the Ague i● cured; Because, as I said before there cannot be a sudden and violent or intense act of putrefying, except there be first a cessation of the act o● Fermenting: so that to continue 〈◊〉 habit of Fermentation, is the way and means to cure an Ague.  
And this is the reason why Strong water and Pepper, and other ho● things of several kinds, both Actual and Potential, being given sometime before the cold fit, do ofte● times cure an Ague. And the reason why those things which do sometimes cure, do also sometimes fail, 〈◊〉 this, viz. Because the habits of fermenting and Putrefying are in ●ome bodies more Intense or Remiss, ●han in othersome. Now that there ●ay be no uncertainty in the cure of ●his disease, which is called Oppro●rium Medicorum, the Physician's ●ame; It is best by the use of Steel gradually to strengthen the habit of fermenting, and to weaken the ha●it of Putrefying first, before any ●ndeavour be done to cure this dis●●se by preventing the cold fit, ●used by the cessation of Fermen●tion.  
And because that in Quartan A●es, the habit of Putrefying is not 〈◊〉 soon weakened as in others, because it is there seated in a tougher ●umour; it will not be amiss to give ●e Patient his Sugar of Steel in Sack ●ther than in water, or at the least 〈◊〉 advise him to drink Sack very often. For it is known by experience, that the much drinking of Sack, doth in a great measure help those that labour of Quartan Agues; probably because the Sack embodying itself with the humour, doth abate its toughness.  
Now suppose there may be some Quartan Ague, especially in the Wintertime, which notwithstanding these means, may yet remain uncured: Yet must the Patient needs receive great benefit by the use of Steel, in that it opens the pores, and provoketh Urine, whereby the Morbific matter, generated by the Quartan, for other diseases may by Urine and Sweat be carried out of the body.   

CHAP. XXI. How Steel may conduce to the Cure of the Stone.  
THe Stone is a disease Obnoxious unto all manner of persons whatsoever, both Men, Women, and Children. I myself have taken out of the Bladder of a Boy of ●bout eight or nine years of age, a ●tone of the bigness of a Hens Egg.  
Stones are bred either in the Bladder or the Kidneys, of Gravel and ●ough Phlegm, and gradually augmented oftentimes unto a very great signess, especially in the Bladder, which are either smooth, or else egged and sharp, according as one ●f those two Materials, whereof ●hey are generated, viz. Gravel or phlegm, is predominant. The smooth ●tones in the Bladder are generated ●hiefly of Phlegm, which oftentimes lying upon the Neck of the Bladder, and couching close unto it, do injury to the body by stopping the passage of the Urine.  
The ragged and sharp Stones in the Bladder, are bred of a greater quantity of Gravel than Phlegm; which oftentimes by their roughness and sharpness, do excoriate and fret the Neck of the Bladder, which is most tightly sensible, whereby the Patient is tortured with extreme pain.  
That a Stone of the greatest bigness may possibly be dissolved, it is without all controversy; for experience hath taught, that many who have been much tormented with the Stone, after they have had several● pieces of Stone comed away with their Urine, have been perfectly well. Besides, reason will very well admit, that whatsoever by accident is generated in the body, may 〈◊〉 well be corrupted and dissolved; according to that Maxim, Qu●●oritur moritur.  
This, even as all other distempers, may be effectually cured, if the cause can be removed. All effects must necessarily cease, when their cause is once taken away. If that sharp Urine, apt to produce gravel, impregnated with a viscous matter, can have its acrimony and viscosity abated, it will then sooner dissolve, than before it did produce a Stone. Now it is well known by experience, that Steel hath a faculty, both to attenuate Phlegm, and to lenify sharp humours; wherefore it cannot be otherwise, but that Steel must needs be a fit Remedy for this Distemper.  
Give the Patient Ten Grains of Sugar of Steel in a Morning Fasting, and as much at Four in the Afternoon, in a draught of Spring-water, for a Month together, and let him Exercise after it if he be able.  
As for his Diet, let him by all means abstrain from New Bread and stolen Beer. Let him abstain also from Cheese, and all manner of Fish, except Shellfish, of which let him eat as often as he will. To drink New Whey often, may be very profitable for him.   

CHAP. XXII. Of the stopping of all manner of Fluxes, by the use of Steel.  
THe word Flux, is a general and comprehensive term, whereby is signified, any violent and sudden evacuation of humours of what kind soever, as well the overflowing of the Months in Women, and the immoderate bleeding at the Nose, as those Fluxes of the Belly, viz. Lienteria, Dysenteria and Tenesmus; for all which, there is not a more Sovereign Remedy than Steel, and that upon a rational account. For whether any Flux may proceed from Putrefaction, or from sharpness of humours, or from both, 'tis ●ot not material, as to any impediment in the Steel to perform the Cure; seeing that Steel, as you may ●ead above in the Nineteenth Chapter, doth both resist Putrefaction, and lenify sharp humours. And besides, that it doth also very much strengthen the Bowels, the weakness whereof is sometimes the cause of some Fluxes of the Belly, it may appear by that quick and sharp appetite which it causeth in all that ●ake it.  

A Case.  
A Boy of thirteen years old, had been troubled with a great looseness by Fits, a year and half, who was thus cured. He drank for a Fortnight together, Ten Grains of Sugar of Steel in Spring-water, twice every day. And after that another Fortnight he drank Morning and Evening a draught of New Milk from the Cow: and so did he do alternately; one Fortnight he drank Milk and another Fortnight Sugar o● Steel in Water, for a Quarter o● a Year.  
A Child of six Years old was cured of a Looseness by a Gad o● Steel quenched in all his Beer he drank.  
A Young Man of Twenty three Years of Age, was much subject to bleeding at the Nose, who for seven Years together, in the Summertime, bled constantly, almost every day, more or less; and after the trial of several things in vain, he was at length cured by the only use of Steel. In the hot Wether when his Bleeding came upon him, he drank twice every day. Ten Grains of Sugar of Steel, in a large draught of Spring-water, for Thirty days. This he did so long in the Summertime, two or three Years together.  
A Woman of Thirty two Years of age, troubled with an immoderate Flux of her Months, was cured by taking Ten Grains of Sugar of Steel twice every day, in Spring-water, for a Fortnight.  
Another Woman not recovered out of Childbed, much troubled with floudding, was cured by taking Eight Grains of Sugar of Steel in a draught of Sack, twice every day for six days.    

CHAP. XXIII. How a Dropsy may be Cured by Steel.  
A Dropsy is a collection of the more serous and watery part of the Mass of blood, from the Veins and Arteries, into several parts of the body, caused through the want of excretion of that waterish humour by Urine and sweat, through the Pores and Ureters. When this waterish moisture is extravassated from the Veins and Arteries, and diffused throughout the whole body, i● is called, Anasarea; when it is collected in the Abdomen, it is called Ascites; when in the Abdomen, and mixed with Flatulency, Tympanites But however it is distinguished by several denominations, the general cause of all is want of Fermentation. For this we are to suppose, that i● there were a just Fermentation o● the Mass of blood, there would no● be those obstructions in the Pore● and Ureters, for that serous humou● to be locked up in the body, which ought to be excluded.  

A Case.  
A young man of about four or five and twenty years of age, was ver● much swelled in all the parts of hi● body with an Hydropic humour who was thus cured.  
He first took a Vomit of the infusion of Crocus Metallorum; after that for six days he drank twice every day, twenty grains of Sugar of Steel in a draught of White-wine and water mixed: then he sweat twice, overnight and the next morning, in a Hothouse. After his sweeting, his swelling being somewhat abated, he was able to walk a little. Then returning to his Sugar of Steel, he drank for six days more, twice every day, half that quantity, viz. ten grains at a time in Water and Wine mixed, exercising as much as he was able after it; and then sweeting twice more as formerly. In the mean time he kept himself as warm as he could possibly, and all his drink was middle Beer, wherein was infused Sage, Broom, and Wormwood.  
Another was cured by the only use of Steel, taking ten grains of Sugar of Steel twice every day in Wine and Water, for the space of three weeks, exercising very well after it; and in the mean time keeping himself as warm as he he could possibly.    

CHAP. XXIV. Of the use of Steel in the Cure of the Strangury, or Pissing by Drops.  
THe word Strangury, signifies in its Original, nothing else but a Pissing by Drops. It is a disease in the Bladder, incident to Aged people and Phlegmatic persons, when the Neck of the Bladder through phlegm is so obstructed, that the Urine cannot pass. It is effectually cured by Steel, that great Attenuatour of Phlegm and Viscous humours.  

A Case.  
An ancient Gentleman of eight and fifty years of age, was often troubled with an Impediment in the making of his water, who was thus cured. At night when he went to bed, he took half a dram of Mercurius Dulcis, mixed with a little Conserve of Red Roses from a knife's point. The next day he began to take Sugar of Steel, whereof he took ten grains at a time, in a draught of White-wine and Water mixed, twice every day for fifteen days together: after that, for other fifteen days, he drank every night so soon as he was in bed, a good draught of White-wine Posset-drink warm. In the mean time he kept himself to warm Diet, which Diet was chief Flesh-meat, and the Broth of Flesh-meat: he abstained from Cheese, New-bread, Stale-beer, and all manner of Fish except Shellfish.  
He kept himself always very warm, and would oftentimes eat Raisins and Figgs between his meals.    

CHAP. XXV. That Steel doth carry away the Relics of those Diseases which it doth not Cure.  
ALthough there are some Diseases which Steel doth rather Prevent than Cure, yet is it useful also in the perfecting and finishing of the Cure even of such Diseases. A Disease cannot truly and properly be said to be perfectly cured, until the Relics of that Disease be quite removed out of the body. And for removing of the Relics of Diseases, I know no better way than to provoke Urine, and to procure a moderate Transpiration; both which are done by the use of Steel. I deny not but that purging Physic may and aught to be given, to such persons who in the time of their health were naturally soluble, for the removing of the Relics of Diseases. But, as I showed before in the fourth Chapter concerning Excretion, Nature doth not primarily intent to separate Excrementitious matter from the Mass of blood, by siege or stool, but by Sweat and Urine; so that solubility of body is but a shift of Nature, when the Ureters and Pores are obstructed, as you may see more at large in the 4 Chap. As therefore the way to preserve health, is to take care rather that the Pores and Urinatory passages be kept open, than that the belly be lose; Even so is the same care to be taken for the Restitution of Health, and Restauration of Strength when the violence of a Fever is once over. Now as in the time of the violence of a Fever (I speak of a putrid Fever) the Physician is constrained to imitate Nature in her shifts, in using Clysters for the Evacuation of that matter, which cannot at that time be carried out of the Body by Urine and Sweat; so afterwards when that violent act of Putrifying, which is Fermentation reversed, is passed, he is much more to Imitate Nature in that which she doth primarily intent, by taking away the Relics of the Disease after the order and course of Nature, by the Pores and Ureters, which victorious Nature after the conquest of the Disease, hath in some measure opened for that intent and purpose.  
And as for the taking away of the Relics of Fevers, Steel which is good to prevent them, is necessary; So is it also altogether as useful and necessary for the taking away the Relics of that Disease wherein it is not at all concerned, either to prevent or cure; I mean the French disease. For certain trial and proof hereof, I appeal to the Experience of those that have been imperfectly cured of that Disease, whether upon some Intemperance, or cold taking, they are not sensible of some returns of their disease. Now seeing that those things which breed other diseases, are a means to recruit this disease when it is imperfectly cured; it followeth by a necessary consequence, that whatsoever doth generally prevent and cure other distempers, must carry away the relics of this. Besides, there is no disease whatsoever, but Nature doth in some measure strive against it; and although Nature may not of herself be able to cure it, yet when it is almost cured, she may be able to perform what remains. Now 'tis well known that Steel doth very much strengthen Nature in all her Offices, in opening the Pores and Ureters, and all other obstructed passages, in lenifing sharp humours, in attenuating others that are viscous and thick, in putting a good consistence upon the Mass of blood, etc. all which it doth effectually perform, by that one individual Act of Fermentation.   

CHAP. XXVI. How Coral may be used for the curing of diseases in young Infants.  
HAving discoursed of the efficacy of Steel, for the Cure of diseases in all persons above seven years old, I am now to Treat of Red Coral for the distempers of Infants. But because the distempers of Infants are not so distinct from each other, as that they can receive so many several denominations, as the diseases of those that are Adult; I cannot be so distinct in my Discourse: I shall therefore by one Case only represent the virtue of Red Coral for the cure of children's diseases. Certainly Nature is much more industrious in attempting of herself, the cure of distempers in young Children than in others; because, in young Children she seldom suffers the disease to come to that height, whereby it can receive any certain denomination (except in the Smallpox, Measells, Rickets and Convulsions) before she is endeavouring to cure it, by throwing out the Morbifick-matter by the Intestines, when she cannot prevent the disease by throwing the same matter out, as it first gathers, by the Pores and Ureters. Now whereas Coral doth as much conduce to the cure of children's diseases, as Steel doth to the cure of others, although the disease fall under no particular denomination, but hath one●y one general appearance from several causes; yet may it be sufficient ●o show the use of Coral in this one Case for all.  

A Case.  
A Child of three years old, had upon it every day an Aguish distemper, consisting of a cold and hot fit; it was also much fallen away in all the parts, except in the belly, which was very much swelled: it was also very Thirsty, and had a great Looseness, which was thus cured. It drank every morning half an ounce of the Syrup of Red Coral, in five or six spoonfuls of Spring-water, and as much after the same manner at four in the afternoon, for the space of ten days. In the Night, when it called for Beer, it had given it small-beer, wherein was infused Rhubarb, Cream of Tartar, and Cinnamon. A dram of Rhubarb sliced, half a dram of Cinnamon bruised, and as much Cream of Tartar finely powdered, were tied up together in a little Rag, and put into a pint of small beer.
