I do not approve of your _Authors_ Doctrine, forbidding Phlebotomy or blood-letting in Fevers, opposite to the received Practice of the Schools; his reason is, that he believes there can be no corruption in the blood. _Corrupted blood_, says he,[1] _cannot be in the veins, neither doth a state of ill juice consist in the veins; for Gangrenes do teach, that nothing of Putrified matter can long persist without a further contagion of it self._ Also he says, _That the blood of the Veins is no otherwise distinguished by its several colours and signs, then as wine is troubled when the vine flourisheth._ To which I answer, first, That I can see no reason why there should not be as well corrupt blood, or an ill state of juice in the veins, as ill humors in the body. Perchance he will say, There is no corruption in the body. But Ulcers do teach the contrary. He may reply, Ulcers are not parts of the body. I answer, 'Tis true; but yet they are evil Inhabitants in the body, and the like may be in the Veins. But surely some men may have corrupted parts of their bodies, and yet live a great while; witness Ulcers in the Lungs, and other parts. But your _Author_ may say, When a part of the body is corrupted, it is no longer an animal Part. I grant it: but yet, as I said, that transformed part may remain in the body some time without destruction of the whole body; and so likewise, when some of the blood, is transchanged from being blood, so as not to be capable to be reduced again, it may nevertheless remain in the veins without definition of the veins, or of the whole body: Neither do I conceive any reason, why corrupt blood should Gangrene in the veins, and infect the adjoyning parts more then corrupted lungs do. Next, as for the comparison of the various colours and signs of the blood, with Wine being troubled when the Vine is flourishing; I answer, That it doth not prove any thing; for we speak of such colours, as are signs of corrupted, and not such as are signs of troubled blood: Besides, it is an unlike comparison; for though Wine may become thick by much fermentation, yet it doth not turn into water, as blood in some sick and diseased persons will do. But corrupted blood may be, not onely in the veins of sick, but also of healthy persons; and the story says, that _Seneca_, when his veins were cut, they would not bleed, although in a hot Bath, by reason that which was in the veins, was rather like a white jelly, then blood, and yet he was healthy, though old; which proves, that it is not necessary for the blood to be so pure and fluid as your _Author_ will have it. The truth is, the more fluid the blood is, the weaker it is; like balsam, the more gummy it is, the stronger it is: but veins, which are the mouth, to receive or suck in juices, as also the stomack which digests the meat that after is turned into blood, may be defective either through weakness, superfluity, obstruction, corruption, or evil and hurtful diet, or through the disorders of other particular parts, which may disturb all the parts in general, as skilful Physicians have observed, and therefore apply remedies accordingly; for if the defect proceeds from weakness, they give strengthening remedies; if from superfluities, they give evacuating remedies; if from evil diets, they prescribe such a course of diet as shall be beneficial, and conducing for the restoring of health to the whole body. But your _Author_, as I perceive, believes the blood to be the chief vital part of the body; which surely it is not: for if it were, the least disturbance of the blood would endanger the life of the whole body, and the least diminution would cause a total dissolution of that animal Creature which has blood: Not but that blood is as necessary as breath for respiration, and food for nourishment of the body; but too much blood is as dangerous to the life of the animal body, as too great a piece of food, which cannot be swallowed down, but doth stick in the throat, and stop the breath, or so much quantity as cannot be digested, for too great a fulness or abounding makes a stoppage of the blood, or which is worse, causes the veins to break, and an evil digestion, makes a corruption, or at least such disorder as to indanger the whole animal Figure. But some veins breed more blood, and some less, and some better, and some worse blood, some hotter, and some colder, some grosser, and some purer, some thicker, and some thinner; and some veins breed rather an evil juice or corrupt matter then pure blood; the truth is, blood is bred somewhat after the manner of Excrements, for the veins are somewhat like the guts, wherein the excrements are digested. But you will say, A man may live without excrements, but not without blood. I answer: a man can live no more without excrements and excremental humors, then he can without blood: but yet I am not of your _Authors_ mind, that bleeding and purging are destructive; for superfluities are as dangerous as scarcities, nay more; like as an house filled with rubbish is in more danger to sink or fall, then that which is empty; and when a house is on fire, it is wisdom to take out the Moveables, but a folly to let them increase the flame. But your _Author_ says, Blood-letting takes not onely away the bad, but also the good blood, by which it diminishes and impairs much the strength of the body. I will answer by way of question, Whether in War men would not venture the loss of some few friends, to gain the victory, or save the whole body of the Army: or whether the destroying of the enemies Army be not more advantageous, then the loss of some few friends? For although some good blood may issue out with the bad, yet the veins have more time, room, and some more power to get friendly juices from the several parts of the body, which will be more obedient, trusty, and true to the life and service of the whole body. But neither Fevers, nor any other distempers, will be more afraid of your _Authors_ words, Stones, Spirits, as also Rings, Beads, Bracelets, and the like toys, fitter for Children to play withal, then for Physicians to use; then an Army of men will be of their enemies Colours, Ensigns, Feathers, Scarfs, and the like; knowing it must be Swords, Pistols, Guns, Powder and Bullets, that must do the business to destroy the enemy, and to gain the victory: Wherefore in Diseases it must be Bleeding, Purging, Vomiting, using of Clysters, and the like, if any good shall be done. 'Tis true, they must well be ordered, otherwise they will do more hurt then good; for Diseases are like Enemies, which sometimes take away our Armes for their own uses. But your _Author_ says again, _That the Matter of a Fever floats not in the veins, nor sits nigh the heart._ I answer: There are several sorts of Fevers; for all Fevers are not produced after one and the same manner, or from one and the same cause, as is very well known to wise and experienced Physicians; but although some Fevers are not in the blood, yet that doth not prove, that the blood is never in a Fever; for sometimes the blood is in a Fever, and not the solid parts; and sometimes the fluid and moveable humors, and not the blood, or solid parts; and sometimes the solid parts, and not the blood, nor the liquid and moveable humors; and sometimes they are all in a Fever; and sometimes onely the radical parts, and neither the blood, humors, nor solid parts: and this last kind of Fever, which is a hectick Fever, in my opinion, is incureable; but the others may be cureable, if there be not too many varieties of distempers, or irregular motions. And as for a Fever in the solid parts, Letting of blood, and taking away the humor, may cure it; for the veins being empty, suck the heat out of the solid parts, which solid parts cannot draw out a distempered heat in the veins, and the opening of the veins gives vent to some of the interior heat to issue forth: Wherefore it is very requisite, that in all sorts of Fevers, except Hectick-Fevers, blood-letting should be used, not onely once, but often; for 'tis better to live with a little blood, and a little strength, which will soon be recovered, then to die with too much, or too hot and distempered blood. Also Purging, but especially Vomiting is very good; for if the humors be in a Feaver, they may infect the vital parts, as also the blood; but if they be not in a Fever, yet the solid parts or blood may do the same, and so make the contagion greater; for the humors are as the moveables in a house, which ought to be cast out if either they or the house should be on fire; and if a disorder proceeds from the error of a particular part, then care must be taken to rectifie that part for the health of the whole: Wherefore Physicians use in some cases Blood-letting, in some Purging, in some Vomiting, in some Bathing, in some Sweating, in some Cordials, especially after much evacuation, in some they prescribe a good diet, and in some they mix and prescribe partly one and partly the other, and in some cases they are forced to use all these remedies; for though great evacuations may cause weakness, yet they often save the life; and there is no Patient, but had rather lose some strength, then life; for life can gather strength again; but all strong men are not always long lived, nor all long-lived men very strong; for many that are but weak, will live to a very old age. Lastly, concerning what your _Author_ says, that there is but one Choler and Phlegme in Nature; I answer, That is more then he knows: for all that is in Nature, is not nor cannot be known by any Particular Creature; and he might say, as well, the same of particular Metals, as that there is but one sort of Gold or Silver, when as there is great difference in the weight, purity, colour, and gloss, of several parts of Gold and Silver; Neither is all Gold found in one place; but some is found in Rocks, some in Sand, some in Mines, some in Stones; and so Silver, some is found in the bowels of the Earth, some in the veins of Stones, and some in other Metals, as Lead, and Iron, and some in Coals. And the like may be said of Choler and Phlegme; for they may be several in several places or parts of the body, and be of different colours, tastes, odours, and degrees of heat or cold, thinness or thickness, or the like; for though there is but one Matter in Nature, yet this onely Matter by its several actions or motions changes into several figures, and so makes several sorts of Creatures, and different particulars in every sort. And thus, _Madam_, I have delivered unto you my opinion concerning the cure of Fevers by Blood-letting: Which I submit to the correction of your better judgment, and rest,

Madam,

_Your faithful Friend_

_and Servant._

_MADAM,_

Your _Author_ is not onely against Phlebotomy or Blood-letting, but against all Purging Medicines, which he condemns to _carry a hidden poyson in them, and to be a cruel and stupid invention._ But certainly he shall not have my assent; for if they be Poyson, they are a very beneficial Poyson; and Physical Purgations, in my opinion, are very necessary and profitable for the prolonging of life, and taking away of diseases, provided they be proper for those diseases in which they are used; and so is Phlebotomy, Vomits, and the like: but Medicines are often wrong applyed, and many times the disease is so various, that it is as hard for a Physician to hit right with several Medicines, as for a Gunner or Shooter to kill with Powder and small Shot a Bird flying in the Air; not that it is not possible to be done, but it is not ordinary, or frequent: neither doth the fault onely lie in the Gun, Powder, or Shot, but in the swiftness of the flight of the Bird, or in the various motion of the air, or in a hidden wind, or mist, or the like; for the same Gunner may perhaps easily kill a Bird sitting in a bush, or hopping upon the ground. The like may be said of Diseases, Physicians, and Medicines; for some diseases have such hidden alterations, by the sudden changes of motions, that a wise Physician will not, nor cannot venture to apply so many several medicines so suddenly as the alteration requires; and shall therefore Physicians be condemned? and not onely condemned for what cannot be helped by reason of the variety of irregular motions, but what cannot be helped in Nature? For some diseases are so deadly, as no art can cure them, when as otherwise Physicians with good and proper medicines, have, and do as yet rescue more people from death, then the Laws do from ruine. Nay, I have known many that have been great enemies to Physick, die in the flower of their age, when as others which used themselves to Physick, have lived a very long time. But you may say, Country-people and Labourers, take little or no Physick, and yet grow most commonly old, whereas on the contrary, Great and rich Persons take much Physick, and do not live so long as the common sort of men doth. I answer: It is to be observed, first, that there are more Commons, then Nobles, or Great and rich persons; and there is not so much notice taken of the death of a mean, as of a noble, great, or rich person; so that for want of information or knowledg, one may easily be deceived in the number of each sort of persons. Next, the Vulgar sort use laborious exercises, and spare diet; when as noble and rich persons are most commonly lazie and luxurious, which breeds superfluities of humors, and these again breed many distempers: For example, you shall find few poor men troubled with the Gout, Stone, Pox, and the like diseases, nor their Children with Rickets; for all this cometh by luxury, and no doubt but all other diseases are sooner bred with luxury, then temperance; but whatsoever is superfluous, may, if not be taken away, yet mediated with lenitive and laxative medicines. But as for Physicians, surely never age knew any better, in my opinion, then this present, and yet most of them follow the rules of the Schools, which are such as have been grounded upon Reason, Practice, and Experience, for many ages: Wherefore those that will wander from the Schools, and follow new and unknown ways, are, in my opinion, not Orthodoxes, but Hereticks in the Art of Physick. But to return to your _Author_, give me leave, _Madam_, to consider what his opinions are concerning the Purging of Choler; _Come on_, says he to the Schools,[1] _Why doth that, your Choler following with so swift an efflux, stink so horribly, which but for one quarter of an hour before did not stink?_ To which it may be answered, That though humors may not stink in themselves, yet the excrements mixt with the humors may stink; also the very passing thorow the excrements will cause a strong savour. But your _Author_ thinks, That _by passing through so suddenly, the humors cannot borrow such a smell of stinking dung from the Intestines._ Truly, 'tis easily said, but hardly proved, and the contrary is manifest by putting clear, pure water into a stinking vessel, which straightway is corrupted with an ill smell. He talks also of _Vitriol dissolved in Wine, which if it be taken, presently provokes vomit; but if after drinking it, any one shall drink thereupon a draught of Ale or Beer, or Water, &c. he indeed shall suffer many stools, yet wholly without stink._ I answer: This expresses Vitriol to be more poysonous, by taking away the natural savour of the bowels, then Scammony, Coloquintida, Manna, Cassia, Sena, Rhubarb, &c. to all which your _Author_ is a great enemy; and it is well known to experienced Physicians, that Medicines prepared by the art of fire are more poysonous and dangerous then natural drugs; nay, I dare say, that many Chymical Medicines, which are thought to be Cordials, and have been given to Patients for that purpose, have proved more poysonous then any Purging Physick. Again your _Author_ says, _It is worthy of Lamentation, that Physicians would have loosening things draw out one humor, and not another, by selection or choyce._ My answer is, That natural drugs and simples are as wise in their several operations, as Chymists in their artificial distillations, extractions, sublimations, and the like; but it has long been observed by Physicians, that one simple will work more upon one part of the body, then upon another; the like may be said of humors. But give me leave to tell you, _Madam_, that if your _Author_ believes magnetick or attractive cures (as he doth, and in whose behalf he makes very long discourses) he doth in this opinion contradict himself. He may say, perhaps, There is no such thing as what Physicians name humors. But grant there be none, yet he cannot deny that there are offensive juices, or moveable substances made by evil, as irregular digestions, which may be troublesom and hurtful to the nature of the body. Or perchance he will say, There are such humors, but they are beneficial and not offensive to the nature of the body. I answer: Then he must make an agreement with every part of the body, not to make more of these humors then is useful for the body. Also he mentions some few that took Purging Physick, and died. Truly so they might have done without taking it: but he doth not tell, how many have died for want of proper and timely Purges. In truth, _Madam_, 'tis an easie thing to find fault, but not so easie to mend it. And as for what he speaks of the weighing of those humors and excrements, which by purging were brought out of some Princes body, and how much by the Schools rules remained, and of the place which should maintain the remainder; I onely say this, that all the several sorts of juices, humors, or moveable substances in a body, do not lie in one place, but are dispersed, and spread all about and in several parts and places in the body; so that the several Laxative medicines do but draw them together, or open several parts, that they may have freedom to travel with their chief Commanders, which are the Purging medicines. But your _Author_ says, the Loadstone doth not draw rust. And I say, no more do Purging drugs draw out pure Matter: for it may be as natural for such medicines to draw or work onely upon superfluities, that is, corrupted, or evil-affected humors, juices or moveable substances, as for the Loadstone to draw Iron; and so it may be the property of Purges to draw onely the rust of the body, and not the pure metal, which are good humors. But few do consider or observe sufficiently the variety of Natures actions, and the motions of particular natural Creatures, which is the cause they have no better success in their cures. And so leaving them to a more diligent inquisition and search into Nature, and her actions, I rest,

Madam,

_Your faithful Friend_

_and humble Servant._
