mediocre to these of a middle age because that old men indures easily hunger next to them that are at the entry of the declining age worse then these young men worst of all boyes for they that are growing hath much of the natural heat and therefore hath much need of nourishment otherwise their body should consume but there is but little heat in old bodies wherefore they need not much nourishment because that too much should choake it Canon XXIX The great cavities in the body in Winter and in the Spring are naturallie hoter then at any other time and the sleep longer wherefore in these the dyat may bee larger heere by the cavities wee must vnderstand the stomacke the whole bellie containing the puddings and the rest of the naturall parts that are appointed for digestion But if yee desire to know why the natural heat is augmented in Winter Arist. attributs the cause to the circumsisting air that is colder chasing by this meanes the naturall heat inward while as in the Summer it extends the selfe ordinarly through the whole body towards the heat that is without as familiar to it Hence is it that in the Summer its substance is dissipat and exhals but in Winter it is holden in and keeped there and therefore all the coctions are the better made Canon XXX As to the forme and maner of dyat one should eat lesse in the Summer the Harvest ofter but in the Winter and Spring more seldome but more aboundantly because in the Summer and the Harvest hardly doth one digest meat in Winter verie easily but in the Spring some way well Canon XXXI Yee must nourish gentlie and repare by little and little the bodies that hath beene extenuat of long time and restore quickly these that hath quickly beene taken down Canon XXXII You must give meat to the sick when as the sicknesse gives intermission or release during the accesse abstaine from giving for meat then is hurtfull because that it withdraws nature from the digestion of the humor to the concoction of the nouritour as also because by it the cause of the disease is augmented Canon XXXIII Among the operations of chirurgerie phlebotomie or drawing of blood keepes the first rank because it is the common remead of diseases which proceeds of plenitud or fulnesse for by it an evacuation is made of the humors equally being for this the most exquisit of all other meanes Canon XXXIV Phlebotomie is not only a remead evacuative but also revulsive and derivative for it is profitable when wee turne the course of the flux to the opposit part or desires to turne it asid to the neighbour part Canon XXXV Wee must draw blood in hot fevers 'till the spirits faile and heart saint if so bee the forces bee strong also in great inflammations and extreame paines for if one draw blood in hot fevers till the heart faint all the body is incontinent cooled and the vehement heat extinguished to diverse after it there followeth a flux of the bellie and a sweat By this meanes some are wholly freed of the fever others receives great ease the vehemencie of their sicknesse having passed This sort of bleeding is likewise good in great inflammations both for the former reasons and for that it stops the flux causing the inflammation and so hinders the growth of the phlegmon by this same it appeaseth the great dolours caused of the heat of the fever and of the inflamtions wherefore there is not found a remead more soveraine for insupportable dolours than it Canon XLV You must draw much blood if the sicknesse doeth vrge and the forces doe permit if not by litle and litle and at diverse tymes for all extreame evacuations are dangerous and cheifly bleeding being al at once Canon XXXVII They to whom purging and blood drawing is profitable ought to be purged and bled in the spring For that season is very proper to make evacuation by phlebotomie or pharmacie because that at that time there is no extraordinar heat for to weaken the body by exhalation nor great cold to make it stiffe by congealing the humors in it nor yet inaequall to disturbe the forces but rather a mediocre temper Canon XXXVIII You must not without great cause or deliberation open a veine to a woman with child because that a woman with child bled is broght to bed before the time if the chyld be great because having drawne blood of a woman with chyld the chyld thereby frustrat of his food famishing in the matrix of the mother breaketh his bonds and seeketh foorth for nourishment and that before the time except the mother abound in blood for then yee may be so farre from fearing it that in the contrar if it be not administrat both the mother the child are in danger as hath beene remarked in the persons of the most illustrious dames in the court of France least the child should be choaked by the too great aboundance of blood Canon XXXIX Purgative medicines should be ordained to cacochymike diseases these that purges the bile to bilious they that phlegme to phlegmaticks and so of the rest for the cure of one cacochymie is made by a purgation which is particularly appropriat to the humor thaâ— exceedes and among the alterative potions the cold are appointed for the hot the hot for the cold the dry for the humids and the humid to the dry for the hot mistemper would be made cold and the cold made hot and such like of the rest Canon XL. Strong potions would be given to strong diseases and gentle medicins to more meik and gentle for extreame remedies are fitest for strong diseases hence the Romane oratour desyrous to show how a curagious man should interprise hazards sayes in the presenting of himselfe to dangers he must imitat the custome of the medicins that handles gently those that are but lightly troubled but in greater diseases are constrained to make vse of remedies more dangerous and doubtsome Canon XLI Wee must expell those things that requyres to be expelled by the wayes most proper whither nature chiefly tends and divert them if they make not there course by the way they ought the physition then ought curiously to mark the motion of nature and the inclination of the humor redounding to that end that if it tend to any place fitting to help it in the contrar if it seek for one vnfitting to hinder it and to draw it off that course So if phlegmatick or melancholick humors take the course downeward and nature haue essayed already to banish by the retract the fever the physition ought to prescribe a clister or some other proper remead for to stir vp nature and if a bilious humor bend vpward and nature strive to expell it at the mouth a vomit is expedient to be taken for that is to draw thither the humor whither nature aimes cheifly and if yee doe otherwise you shall change the order and course of nature

TO THE RIGHT HONORABLE Sir THOMAS HOPE of Craighall Knight Baronet Advocat generall to his Majestie of great Britaine in his Kingdome of Scotland Wisheth all health and happinesse c. IT is reported of Caesar Right Honourable that oft times he praised his Souldiours good-will although they wanted skill And Cicero aswell commended stammering Lentulus for his painful industry as learned Laelius for his passing eloquence Which considered although wisedome did will mee not to straine further than my sleive would stretch I thought good to present this small Treatise to your H. protection hoping your H. will out of your accustomed clemencie accept it and take my well meaning for an excuse of my boldnesse in that my poore will is not in the wane whatsoever this imperfect worke doth want The Emperour Trajan was never without suters because so courteously hee would heare everie complaint The Lapidaries continually frequented the Court of Adobrandinus because it was his chiefe study to search out the nature of stones All that courted Atlanta were hunters and none sued to Sapho but Poëts Wheresoever Mecaenas lodgeth thither no doubt will Schollers flocke And your H. beeing a worthie favourer and fosterer of learning hath forced many through your exquisit vertue to offer the first fruits of their study at the shrine of your Courtesie But though they have waded farre and found mynes and I gadded abroad to get nothing but mytes yet this I assure my selfe that they never presented you their treasure with a more willing mind â—hen I doe this simple trash which I hope your H. will so accept Resting â—herefore upon your wonted clemenâ—ie I commit you to the Almighâ—ie I.

M. THE PRACTISE OF PHYSICKE CANON I. THE methodick practising in Physick hath first a knowledge of the disease next fortelleth the event of it and last goeth about to cure the same For that part of Physick which is called Therapeutick followeth still the diagnostick prognostick for whosoever wil vse profitable remedies shuld first remark the things present next forwarn the future because it is necessare to vnderstand the present estate of the disease to that end that the remedies proper may be vsed then to foresee that which is to come for the more boldly attempting of the cure if there bee hope of health or else to foretell the danger if one doe feare death otherwise to abstaine wholly from the interprise if one doth feare inevitable death for wee should never interprise the cure of desperat diseases much lesse promise health or at the least take the busines in hand after a due premonition of the danger of it Canon II. Now to come to the perfect knowledg of the disease ye must first search the place next the kind and then the cause if the place bee manifest of the selfe it resteth to find out the espece of disease and then the cause Canon III. The place is knowne by the action hurt or hindered by the sort and seat of the paine by the excrements and accidents or proper symptomes although that all these signes doe not at all tymes appeare all together yet still some of them doth kyth Canon IV. The action offended showes the part from whence it proccedes to be indisposed for a functioun animall vitall or naturall beeing troubled declares some of those parts to be affected so the hurt of the reason imagination and memorie showes the braine to be sicke the losse of sense and motion manifests the nerves or else there origine to be grieved difficultie of breathing wills the lights or some of the instruments of respiration to bee interessed the pulse commoved shows the heart to be troubled The stop of the discent of the meat shewes the vizorne to bee hurt the digestion hindred the stomack when the body is not nourished the lever is mistempered The espece or sort of sicknesse points foorth also the place so a paine with a pulsation is from the nerve hurt or offended with punction from the membrane distended with convulsion from the drawing of the nerves or tendons with violence dolour with tension shewes the veines repletion out of measure when it is profound it declares the membran covering the bone called Periostium to bee diseased when soft and gentle without great paine it is in the flesh when heavie and blunt it points foorth some of the intrels to bee grieved The situation of the paine makes known the seat of the disease also so if it bee in the right hypochondre or vnder the short ribs on the right side it declares the lever to be hurt if vnder the left side the melt for wheresoever is the paine there is the sicknesse wherefore wee must not omit to inquyre of the sick person on which side hee lyes with greatest ease for if it be without he lyes best on the whole side but if within best on the sore That which issueth foorth of the body indicats also the part affected so if by cough there is thrown foorth any part of a girstle there is no doubt the light pypes are torne if in the water there is found any peece of flesh it betokens the neers to bee hurt if in the draught there is found any peece of skin it signifies the puddings to be vlcerat The stomack is known to bee hurt when the meat or chile doth issue foorth at the wound and if the fecall mater come foorth it shews the puddings to be wounded so the water issuing wills the bladder to bee wounded and when the Pleura that covers the ribs
Canon VI. Among the constititions of the seasons the dry is more wholesome and not so deadly as the rain for it gathereth no excrements and resists better to the putrefaction the humid in the contrar causes many superfluities from whence are the generation of diseases when the seasons are constant keeping there temperature ordinar so that all things doth naturally fall out in them the diseases are lykewayes constant and facily to be vnderstood but when the season is inconstant so are the sicknes variable and hard to be vnderstood for there crise is accompanied with dangerous symptomes where they suddenly cause death or ells leaves a matter to a new sickenesse When the sicke proves a good second to the physitian fighting againes the sicknes it is easie to obtaine the victorie Now when he beleues the physition and puts in practise his ordinances hee serves him for a second and declares himselfe enemie of the disease in the contrar if quyting the physition he takes part with the disease accomplishing that which hee desyres he hazards his life two wayes the one in leaving the physition aboue in combat the other in serving as a second to the sickenesse which was before alone for it is certaine two is stronger nor one Canon VIII The greatnes of the sickenesse followes the greatnes of the cause for as a light cause produces a light evill even so a great causeth a great Hence a vehement cause contrar nature is a most certaine indice of a great and dangerous sicknes Canon IX Byle causes still quicke diseases which are termined or ended within few dayes because it is easilie resolved by its subtilitie but melancholie is the most viscuous of all the humors and makes longest accesses because it is dry cold and thicke being the lyfe of the blood Next to melancholy is phlegme in difficulty of digestion and expulsion by reason of its viscositie Canon X. The diseases that hath some resemblance with the nature bodily constitution and age of the diseased are lesse dangerous then these that hath no conformity for all sicknesse hot cold dry moist being conforme to the complexion age and bodily constitution of the sicke and also to the season hath so much lesse danger as it is lesse removed from the naturall constitution and so may more easily returne as proceeding frō a lighter yea a slighter cause As in the contrare the disease that hath no affinity neither with the temper taillie nor age of the Patient or with the season is much more dangerous then the former being further removed from the naturall complexion and therefore worse to cure as proceeding of a greater and stronger cause So that of two burnt fevers equall in grandure that which fals out in the Summer to a young man leane of body of temper hot shall not be so dangerous as that which fals out in the Winter to an old man of a fat body and cold complexion Canon XI Meeke and gentle relenting diseases are commonly long but the sharpe fyrie and fierce are ended within fourteene dayes and the extreame hot in seven dayes There can no certain prediction be made of hot sharp diseases either for health nor death for by that they are quickly ended they become on a suddaintie great so that both for the greatnesse of the disease with the suddaine change which befals in the crise as also because the humor is often transported from one place to another the issue is vncertaine wherefore while the humor is in its motion we must suspend our judgement for it is not certain whether it will rush on a noble or ignoble part within or without by passages conveniable or not conveniable thogh the humor were staied in one place yet the Physician ought not resolutly affirme that the sick shall escape but with this provision that no new change befall and that hee follow the advise and keep the regiment prescribed When a woman with child is overtaken by any firie hot disease shee is in danger of her life for a hot fyrie fever requyres a strait dyet which shee cannot admit least the child being frustrat of his food shee be broght to bed before the time and if oft to save the child yee give the mother often to eat the fever thereby growing yee shall precipitat the mother in a manifest hazard of her life and if it be any other strong sicknesse without fever as a epilepsie apoplexy convulsion shee shall never be able to support the vehemencie of it Canon XII To foretell the event of the disease yee must consider diligently the part that is offended whether it bee noble or ignoble publick or privat for the condition dignitie and necessitie of the part that suffereth are of great importance for the pronouncing of a sentence to the profit or prejudice of the sick Canon XIII In all diseases the constancie of the reason not troubled with the bounty of the appetit still readie for taking of whatsomeever shall bee offered to it is a good signe and the contrare is an evill the satlednesse of the reason and sharpnesse of the appetit are numbred among the good markes because the former beares witnesse of the temperat disposition of the braine the menings or tayes of the harnes and of the marrow of the backe the medrife and all the nervous parts and the latter shews the integritie of the stomack and lever In the contrare the alienation and troubling of the reason and the losse of appetit are evill signes because the one betokens the animal parts to be affected the other the naturall All they that are troubled with paine or dolour in any part of the body whatsomeever and are not sensible of it hath the reason troubled because the apprehension doth not perceiue in any measure the evill Canon XIV It is good to sleep in the night to make reparation of the spirits animals and digestion of the humors by the meanes of the heat that enters within the center of the body and to watch in the day for the clearing of the same spirits to give motion to the humors and to make expulsion of the excremēts but it is a verie pernicious signe not to sleepe night nor day for continuall watching commeth either of the dolour paine and torment that they suffer or of the drynesse of the braine which in end will cause an alienation of the mind Sleepe likewise surpassing the borders of mediocrite is in like maner evill because it is a marke of extreame coldnesse of the braine which causeth a lethargie if it bee mixed with humidity or catalepsie if with drynesse When in a sicknesse sleepe is noysome and hurteth there is danger of death for if the sleep hurts that time that hath bene accustomed to helpe much as in the decline of any sicknesse it is not without cause that it foretelleth death and that because the heat reteared within the body the time of the sleep and by this meanes increase Notable neverthelesse
are markes of force but the small and extenuat are evill both as signes and as causes forasmuch as they are signes of the debilitie of the parts extenuat and causes that the digestion is not well elaborat in the stomack nor the sanguification in the lever for the grossenesse or fatnesse of the epigastre or low parts of the belly augments the natural heat by the which the parts within being warmed they digest better the meat and so makes better blood Canon XXIV As to the consideration of these things that fals out in the body if yee remarke any good signe yee must not thinke for that that assuredly the sick shall escape neither although there do appeare any evill signes that hee shall die for a good signe may bee over weighted by an evill being great And on the contrare an evill may be overcome a good being stronger Canon XXV The disease quyts the sick either wholly at once by way of crise or by litle and litle by way of resolution Crise is a suddaine change of the disease into health or else into death which is then when nature separats the vitious humours from the good and that for to expell them Of it there bee two sorts the one is by excretion and the other by absesse that comes by a flux of blood or sweat or a flux of the bellie or vomit or flux of the vrine Canon XXVI The good crise arives on the 7.14 or 20 day wherefore these dayes are called Criticks The future crise was foreseene by the signes of digestion appearing the 4.11 and 17. day hence these dayes are called of of the Greeks 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 that is in dicatives contemplatives for according to the doctrine of Hip. the 4. day is the indicative of the 7. the 8. is the beginning of the next moneth the 11. is also remarkable because the fourth of the second weik the 17. is also to bee observed because the 4. after the 14. and the 7. from the 11. Canon XXVII When the crise is to bee on the 7. day there is perceived on the fourth day preceding a red cloud in the water and other signes correspondent for because the 4. day is the pointer out of the 7. if there appeare any signe of concoction that day it forwarnes the crise to bee on the 7. day Where then there appeares a clowd in the water not only red but whyt and yet rather a whyt hypostasies or ground vnited and equall if so bee the motion of the sicknesse bee suddaine it is a presage of the future crise When the crise draws neare the night preceeding is verie troublesome but that which follows is ordinarly more easie to indure For while nature is making a separation betwixt the good and evill humors that fals out that in this exercise of nature the disease is much troubled But so it is that this great worke appeares the night before the crise because the sleepe is interrupted but the night that follows the crise perfyte they are much more at their owne ease because nature is disburdened of superfluous humors Canon XXVIII The vniversall signes by the which one discernes the espece of the crise to come are taken from the kind of the disease from the part that is diseased and from the nature of the Patient For hot and quicke diseases are ordinarly judged by excretion but the cold and long by abscesse If there bee an inflammation in the gibbous part of the lever yee must expect a crise by a flux of blood at the right nostrile or by a flux of the vrine if the inflammation bee in the hollow part of it then yee must expect it by a flux of the belly or vomishment or sweat The inflammations of the braine and of all the head are commonly judged by an haemorragie at the nose but that of the stomack and mesenterie by vomishment or a flux downeward Moreover a flux of blood fals oftenest to young men cholericks overtaken with a hot fever and a flux of the bellie to old men phlegmaticks There the common and now heere the proper prognosticks of everie crise Rednes of the face extreame dolour of the head and the necke a beating of the arters in the temples the distention of hypochondres with dificultie of breathing a dimnes tnd watering of the eys singing of the eares and itching of the nostrell◠prognosticks the crise to be a flux of blood by the nose A heat and heavines of the loynes with a paine and extention of the hypograster foreshowes a crise to be by a flux menstruall A suppression of the water with a pricking shivering through the whole bodie with the pulse soft and waterie and the exteriour parts of the bodie hote and vaporous betokens that it will be by sweat Rifts ventosites or winds a bending of the belly and paine of the neires by a flux of the belly losse of appetit or lothing of meat with a thrawing of the heart and sorenes of the head with a dissinesse great spitting bitternesse in the mouth and a trembling of the vnder lip prognosticks a future crise by vomit When the signes of concoction hath gone before and when the motions of a crise hath beene perceived then it may be exspected by a flux of the vrine if there doeth not appeare any marke of a crise by a flux of blood not by sweat flux of the belly vomit and specialy when the patient feels an heavines in the hypograster and an heat about the end of the privie member having also made much water thicke and grosse during his disease or if he be aged and sick in the Winter it foretells it the rather A heavines and paine of the head with a profoundity of sleepe and deafnesse succeeding immediatly to a difficultie of breathing suddenly ariving without any manifest cause to one sick with a long disease points foorth an absesse to be behind the eare But if there be no signe of a paritude and that the sicke hath had his vrine of a long tyme cleare and vndigested and when he finds a heavinesse a paine a bending or tension a heat in the hypochondres ye must exspect an absesse in the lower pairts If any part of the bodie hath beene hurt before there shall the aposteme or absesse be An absesse falls out most frequently in winter and after on imperfyt crise Canon XXIX Moreover a good crise ought to be signified before in the day of indication and should fall out in a critike day with a manifest excretion or notable absesse without dangerous accidents It ought also to be perfyt I call a perfyt crise that which evacuats all the vitious mater And on imperfyt that which evacuats but one part for the former is sure but you must not beleeve the latter for the evill humors remaining after a crise are wont to make one recidiwe Moreover a crise is iudged to be good by reason of the convenable qualitie and reasonable quantity with the forme agreable
and the time opportune A crise is knowne to be perfyt and assured by the restablishing of the functions naturalls vitals and animalls by the coction of the excrements or by qualitie or forme of the body reduced and made conforme to the naturall Canon XXX Yee must not trust to any ease or aleagment which falls without cause nor feare evill symptomes ariving against reason for the most part of those are inconstant and doth not last a long time for when any vehement diseases ceaseth of the selfe without any evacuation either by sweat vomit flux downward or hemorrage vpward or without any signe of concoction one must not take that ease to be assured neither must one beleeve to it seing it doth threaten with something of greater evill which follow thereon As also one must not be affraighted of the evills that befalls without or rather contrare reason as difficultie of breathing raverie shiviring reduplication of the fever seing they are not constant nor of long last and so farre from signifying any thing evill that on the contrar they presage often a good crise which shall arive to the great ease of the patient The right methode of curing the disease Canon I. WHosever will exactly keepe the method of right proceeding in the cure ought to begin at the first indications then come to those that followes them Afterward to the next and never leave off till they haue come to the end pretended Wee take heere indication for that which serves to teach vs the way in the cure of the disease to attaine to health Canon II. The forces before all things ought to be keeped in those who are diseased after the indication of the forces followes the consideration of the indisposition which is proposed to be cured The forces wills allways their conservation and the indisposition its ablation Now as the forces are keeped or conserved by their like so the indisposition is taken away by the contrary Canon III. In all diseases where the efficient cause is yet present you must begin your cure at the same for it is impossible to cure perfytly any disease whileas the cause that doth ingender it is present so the maladies ceaseth never till the evill humors ingendring them bee banished which doth lurke within the body Canon IV. After the taking away of the cause you must next turne you to the disease ingendred of the cause keeping for a generall rule first the ablation of the cause efficient and next of the maladie Canon V. The cure of the symptome is never first intended but alwayes that of the maladie which causeth the symptome Yet when the symptome minaceth with death or greater and suddainer danger then the disease it selfe the cure of it may bee first attempted Canon VI. While as the disease is growing wee must hinder the growth of it and take away that part that is already ingēdred The generation of that which is to come is hindred by taking away the cause antecedent and the maladie alreadie ingendred is banished by taking away the cause conjoynt Canon VII In all diseases caused of fluxion yee must first stoppe that which floweth yet next draw foorth that which already is flowed Therefore the cure of a phlegmon catarrhe and of all other diseases that are caused by a fluxion lookes all to two buts the first is that the humour which runneth yet bee stayed the other that that part of it which is already in the part bee evacuat Canon VIII In all diseases complicate the one whereof cannot be cured without the other there must respect bee holden to order now method or order requyres still the cure of that first which hindreth the cure of the other as if a phlegmon were accompanied with a vlcer yee must first take away that then cicatrize this Canon IX When two indications are directly opposit one to another yee must not regard so the one that yee misregard the other but rather having as good mind of this as of that make a mixture as equall as ye can As for example if one be troubled by two so contrarie diseases that the one desires a hot the other a cold remead yee must then make vse of one temperat to that end it do harme neither to the one nor to the other but rather help both So when the stomack is cold and the lever over hot things temperat are convenable and all that is mixtioned of hot and cold things or the alternative vse of the one and the other Hence is it that when a phlegmon is in its grouth there is mixed repercussives with digestives Canon X. When there is remarked a repugnance among the indications after you haue well considred that which is taken from the forces and also the indication of the cause the disease thou shall follow the most important of all not neglecting howsoever the other Canon XI It is a maxime most necessarie that commands to cure first the most importunat danger For the indisposition that is the first principall cause of precipitating the diseased in any danger ought first to bee helped Wherefore excessive watching cruell paine all evacuation out of measure chiefly of blood the suppression of superfluities and other like symptomes which weakens the forces and augments the disease in such sort that there may arrive quickly some danger constraines often the Physitian to quyt the cure of the sicknesse to occur to these symptomes Canon XII The generall method of curing diseases is accomplished by the convenable quantity and quality of the remedies with the maner and time of vsing of them Canon XIII It is requyred that all the remedies bee contrare in quality to the disease for contraria contrariis curantur For if all that which is immoderat be contrare to nature and that which is moderat agreeable to nature of necessitie it will follow that that which is out of measure must bee brought to measure by its contrare in like degree out of measure Hence is it that all diseases ingendred of repletion are cured by evacuation and these that proceed of evacuation by repletion and such like of the rest Canon XIV The temper of the body diseased with the disease it selfe shews the measure of the contrarietie forasmuch as it is not enough to apply cold remedies to a hot disease if that be not done with a measure reasonable otherwise not equall in measure it is to bee feared that there remaine some portion of the disease or being excessive that one disease contrar to the other bee moved For to occur to this wee must know the nature of the body that is to be handled to that end that vnderstanding how farre the disease exceeds mediocritie one may exactly measure the proportion of the refrigeratiue remedie Therefore the quantity of everie remead ought to be measured according to the complexion of the sick and the greatnesse of the sicknesse Canon XV. The contrare remedies must be put in vse litle by litle and now and
