canon XII the spirit in great quantity hasten more to fly forth and prey upon  the body more than it small quantity the explication this canon be clear of it  self see mere quantity do regular increase virtue and it be to be see in flame  that the big they be the strong they break forth and the more speedy they  consume and therefore over great or exuberance of the spirit be altogether  hurtful to long life neither needs one wish a great store of spirit than what  be sufficient for the function of life and the office of a good reparation  canon XIII the spirit equal disperse make less haste to fly forth and prey  less upon the body than unequal place the explication not only abundance of  spirit in respect of the whole be hurtful to the duration of thing but also  the same abundance uneven place be in like manner hurtful and therefore the  more the spirit be shred and insert by small portion the less it prey for  dissolution ever begin at that part where the spirit be lose and therefore  both exercise and Frications conduce much to long life for agitation do fine  diffuse and commix thing by small portion canon xiiii the inordinate and  Subsultorie motion of the spirit do more hasten to go forth and do prey upon  the body more than the constant and equal the explication in inanimate this  canon hold for certain for inequality be the mother of dissolution but in  animate because not only the consumption be consider but the reparation and  reparation proceed by the appetite of thing and appetite be sharpen by variety  it hold not rigorous but it be so far forth to be receive that this variety be  rather a alternation or interchange than a confusion and as it be constant in  inconstancy canon XV the spirit in a body of a solid composure be detain  though the explication all thing do abhor a solution of their continuity but  yet in proportion to their density or rarity for the more rare the body be the  more do they suffer themselves to be thrust into small and narrow passage for  water will go into a passage which Dust will not go into and air which water  will not go into nay flame and spirit which air will not go into  notwithstanding of this thing there be some bind for the spirit be not so much  transport with the desire of go forth that it will suffer it self to be too  much discontinue or be drive into overstrait poor and passage and therefore if  the spirit be encompass with a hard body or else with a unctuous and tenacious  which be not easy divide it be plain bind and as I may say imprison and lie  down the appetite of go out wherefore we see that metal and stone require a  long time for their spirit to go forth unless either the spirit be excite by  the fire or the gross part be dissever with corrode and strong water the like  reason be there of tenacious body such as be gum save only that they be melt  by a more gentle hear and therefore the of the body hard a close and compact  skin and the like which be procure by the dryness of the aliment and by  exercise and by the coldness of the air be good for long life because they  detain the spirit in close prison that it go not forth canon XVI in oily and  fat thing the spirit be detain Willing though they be not tenacious the  explication the spirit if it be not irritate by the antipathy of the body  enclose it nor feed by the over much likeness of that body nor solicit or  invite by the external body it make no great stir to get out all which be want  to oily body for they be neither so press upon the spirit as hard body nor so  near as watery body neither have they any good agreement with the air ambient  canon XVII the speedy fly forth of the watery humour conserves the oily the  long in his be the explication we say before that the watery humour as be  consubstantial to the air fly forth soon the oily late as have small agreement  with the air now whereas these two humour be in most body it come to pass that  the watery do in a sort betray the oily for that issue forth insensible carry  this together with it therefore there be nothing that more further the  conservation of body than a gentle dry of they which cause the watery humour  to expire and invite not the oily for then the oily enjoy the proper nature  and this tend not only to the inhibit of putrefaction though that also follow  but to the conservation of greenness hence it be that gentle Frications and  moderate exercise cause rather perspiration than sweat conduce much to long  life canon XVIII air exclude conftrreth to long life if inconvenience be avoid  the explication we say a little before that the fly forth of the spirit be a  redouble action from the appetite of the spirit and of the air and therefore  if either of these be take out of the way there be not a little galned  notwithstanding diverse inconvenience follow hereupon which how they may be  prevent we have show in the second of our ten operation canon nineteeen  youthful spirit iuserted into a old body may soon nature course back again the  explication the nature of the spirit be as the uppermost wheel which turn  about the other wheel in the body of man and therefore in the intention of  long life that ought to be first place hereunto may be add that there be a  easy and more expedite way to alter the spirit than to other operation for the  operation upon the spirit be twofold the one by aliment which be slow and as  it be about the other and that twofold which be sudden and go direct to the  spirit namely by vapour or by the affection canon twenty juice of the body  hard and full of dew be good for long life the explication the reason be plain  see we show before that hard thing and oily or full of dew be hardly dissipate  notwithstanding there be this difference as we also note in the ten operation  that juice somewhat hard be indeed less dissipable but then it be withal less  reparable therefore a convenience be interlace with a inconvenience and for  this Cause no wonder matter will be achieve by this but full of dew juice will  admit both operation therefore this will be principal canon XXI whatsoever be  of thin part to penetrate and yet have no acrimony beget full of dew juice the  explication this be more hard to practice than to understand for it be  whatsoever well but yet with a sting or as do all sharp and sour thing it  leave behind wheresoever it go some mark or print of dryness cleave so that it  the juice and the part contrary whatsoever thing penetrate through their  thinness mere as it be by stealth and by way of insinuation without violence  they bedew and water in their passage of which sort we have recount many in  the four and seven operation canon XXII assimilation best when all local  motion be suspend the explication this canon we have sufficient explain in our  discourse the canon XXIII alimentation from without at least some other way  than by the stomach be most profitable for long life if it can be do the  explication we see that all thing which be do by nutrition ask a long time but  those which be do by embrace of the like as it be in infusion require no long  time and therefore alimentation from without will be of principal use and so  much the more because the of decay in old age so that if there can be some  auxiliary Natritions by bath unction or else by clyster these thing in  conjunction may do much which single be less available canon xxiiii where the  concoction be weak to thrust forth the aliment there the outward part shall be  strengthen to call forth the aliment the explication that which be propound in  this canon be not the same thing with the former for it be one thing for the  outward aliment to be attract inward another for the inward aliment to be  attract outward yet herein they concur that they both help the weakness of the  though by diverse way canon XXV all sudden renovation of the body be wrought  either by the spirit or by Malacissations the explication there be two thing  in the body spirit and part to both these the way by nutrition be long and  about but it be a short way to the spirit by vapour and by the affection and  to the part by Malacissations but this be dillgently to be note that by no  mean we alimentation from with malacissation for the intention of  malacissation be not to nourish the part but only to make they more fit to be  nourish canon XXVI malacissation be wrought by Consubstantials by Imprinters  and by closers up the explication the reason be manifest for that  Consubstantials do proper supple the body do carry in closers up do retain and  bridle the perspiration which be a motion opposite to malacissation and  therefore as we describe in the nine operation malacissation can well be do at  once but in a course or order first by exclude the liquor by Thickners for a  outward and gross infusion do not well compact the body that which enter must  be subtle and a kind of vapour second by intenerate by the consent of  Cousubstantials for body upon the touch of those thing which have good  agreement with they open themselves and relax their poor three Imprinters be  convoy and insi nuate into the part the Consubstantials and the mixture of  gentle astringent do somewhat restrain the perspiration but then in the place  follow that astriction and closure up of the body by and then afterward by  until the supple be into solid as we say in the proper place canon XXVII  frequent renovation of the part reparable water and renew the less reparable  also the explication we say in the preface to this history that the way of  death be this that the part reparable die in the fellowship of the part less  reparable so that in the reparation of these same less reparable part all our  force will be employ and therefore be admonish by Aristotle observation touch  plant namely that the put forth of new shoot and branch refresh the body of  the tree in the passage we conceive the like reason may be if the flesh and  blood in the body of man be often renew that thereby the bone themselves and  membrane and other part which in their own nature be less reparable partly by  the cheerful passage of the Iuyees partly by that new Clouthing of the young  flesh and blood may be water and renew canon XXVIII refrigeration or cool of  the body which pass some other way then by the stomach be useful for long life  the explication the reason be at hand for see a refrigeration not temperate  but powerful especial of the blood be above all thing necessary to long life  this can by no mean be effect from within as much as be requisite without the  destruction of the stomach and bowel canon XXIX that intermix or entangle that  as well consumption as reparation be the work of heat be the great obstacle to  long life the explication almost all great work be destroy by the nature of  thing intermix when as that which help in one respect hurt in another  therefore man must proceed herein by a sound judgement and a discreet practice  for our part we have do so as far as the matter will bear and our memory serve  we by separate benign heat from hurtful and the remedy which tend to both  canon XXX cure of disease be effect by temporary medicine but lengthen of life  require observation of diet the explication those thing which come by accident  as soon as the cause be remove cease again but the continue course of nature  like a run river require a continual row and sail against the stream therefore  we must work regular by diet now diet be of two kind set diet which be to be  observe at certain time and familiar diet which be to be admit into our daily  repast but the set diet be the more potent that be a course of medicine for a  time for those thing which be of so great virtue that they be able to turn  nature back again be for the most part more strong and more speedy alter than  those which may without danger be receive into a continual use now in the  remedy set down in our intention you shall find only three set diet the opiate  diet the diet malacissant or supple and the diet Emaciant and renew but among  those which we prescribe for familiar diet and to be use daily the most  efficacious be these that follow which also come not far short of the virtue  of set diet nitre and the subordinate to nitre the regiment of the affection  and course of our life which pass not by the stomach drink Roscidating or  England ndring oily juice besprinkle of the blood with some firm matter as  pearl certain wood competent unction to keep out the air and to keep in the  spirit heater from without during the assimilation after sleep avoid of those  thing which inflame the spirit and put it into a eager heat as wine and spice  last a moderate and seasonable use of those thing which endue the spirit with  a robust heat as saffron cress garlic elecampane and compound opiate canon  XXXI the live spirit be instant extinguish if it be deprive either of motion  or of refrigeration or of aliment the explication namely these be those three  which before we call the porch of death and they be the proper and immediate  Passios of the spirit for all the organ of the principal part serve hereunto  that these three office be perform and again all destruction of the organ  which be deadly bring the matter to this point that one or more of these three  fail therefore all other thing be the diverse way to death but they end in  these three now the whole fabric of the part be the organ of the spirit as the  spirit be the of the reasonable soul which be incorporeous and divine canon  XXXII flame be a momentany substance air a fix the live spirit in creature be  of a middle nature the explication this matter stand in needs both of a high  indagation and of a long explication than be pertinent to the present  inquisition mean while we must know this that flame be almost every moment  generate and extinguish so that it be continue only by succession air be a fix  body and be not dissolve for though air beget new air out of watery moisture  yet notwithstanding the old air still remain whence come that super oneration  of the air where of we have speak in the Title de vent be but spirit be  participant of both nature both of flame and air Even as the nourishments  thereof be aswell oil which be homogeneous to flame as water which be  homogeneous to air for the spirit be not either of oily alone or of watery  alone but of both together and though air do not agree well with flame nor oil  with water yet in a mix body they agree well enough also the spirit have from  the air his easy and delicate impression and yield and from the flame his  noble and potent motion and activity in like manner the duration of spirit be  a mix thing be neither so momentany as that of flame nor so fix as that of air  and so much the rather it follow not the condition of flame for that flame it  self be extinguish by accident namely by contrary and enemy environ it but  spirit be not subject to the like condition and necessity now the spirit be  repair from the lively and florid blood of the small artery which be insert  into the brain but this reparation be do by a peculiar manner of which we  speak not now Finis
