A35987	Two treatises in the one of which the nature of bodies, in the other, the nature of mans soule is looked into in way of discovery of the immortality of reasonable soules.	Digby, Kenelm, Sir, 1603-1665.	1644 (1644)	Wing D1448; ESTC R9240	548,974	508

in for a pretty while without any extreme preiudice But these difficulties are easily answered for whether beasts harts do lye directly horizontally or whether the basis be fastened some what higher then the tippe reacheth and so maketh their hart hang inclining downewardes still the motion of grauity hath its effect in them As wee may perceiue in the hart of a viper lying vpon a plate and in any other thing that of it selfe swelleth vp and straight againe sinketh downe in which we can not doubt but that the grauity fighting against the heate maketh the eleuated partes to fall as the heate maketh them rise And as for the latter it is euident that men can not stay long in that posture without violent accidents and in any litle while we see that the bloud cometh into their face and other partes which naturally are situated higher but by this position become lower then the hart and much time is not required to haue them quite disordered and suffocated the bloud passing through the hart with too much quickenesse and not receiuing due concoction there and falling thence in too great aboundance into places that can not with conueniency entertayne it But you will insist and aske whether in that posture the hart doth moue or no and how And to speake by guesse in a thing I haue not yet made experiences enough to be throughly informed in I conceiue without any great scrupule that it doth moue And that it happeneth thus that the hart hanging somwhat loose must needes tūble ouer and the tippe of it leane downewardes some way or other and so lye in part like the hart of a beast though not so conueniently accommodated and then the heate which maketh the viscous bloud that is in the substance of the hart to ferment will not faile of raising it vp wherevpon the weight of that side of the hart that is lifted vp will presently presse it downe againe And thus by the alternatiue operations of these causes the hart will be made to open and shutt it selfe as much as is necessary for admitting and thrusting out that litle and disorderly coming bloud which maketh its course through it for that litle space wherein the man continueth in that position Now from these effects wrought in the hart by the moystening of the fibers two other effects do proceed the one is that the bloud is pushed out of euery corner of the hart with an impetuousnesse or velocity The other is that by this motion the spirits which are in the ventricles of the hart and in the bloud that is euen then heated there are more and deeper pressed into the substance of the hart so that you see the hart imbibeth fresh vigour and is strengthned with new spirits whiles it seemeth to reiect that which should strengthen it Againe two other effects follow this violent eiection of the bloud out of the hart The one is that for the present the hart is entirely cleansed of all remainders of bloud none being permitted to fall backe to annoy it The other is that the hart finding it selfe dry the fibers do relent presently into their naturall positiō and extensiō and the valuulae that open inwardes fall flatt to the sides of the ventricles and consequently new bloud droppeth in So that in conclusiō we see the motion of the hart dependeth originally of its fibers irrigated by the bloud and not from the force of the vapour as Monsieur des Cartes supposeth This motion of the hart driueth the bloud which is warmed and spiritualised by being boyled in this furnace through due passages into the arteries which frō thē runneth into the veines and is a maine cause of making and nourishing other partes as the liuer the lūgs the braines and whatsoeuer else dependeth of those veines and arteries through which the bloud goeth Which being euer freshly heated and receiuing the tincture of the harts nature by passing through the hart wheresoeuer it stayeth and curdleth it groweth into a substance of a nature conformable to the hart though euery one of such substances be of exceeding different conditions in themselues the very grossest excrements not being excluded from some participation of that nature But if you desire to follow the bloud all along euery steppe in its progresse from the hart round about the body till it returne backe againe to its center Doctor Haruey who most acutely teacheth this doctrine must be your guide He will shew you how it issueth from the hart by the arteries from whence it goeth on warming the flesh vntill it arriue some of the extremities of the body and by then it is growne so coole by long absence from the fountaine of its heate and by euaporating its owne stocke of spirits without any new supply that it hath neede of being warmed a new it findeth it selfe returned backe againe to the heart and is there heated againe which returne is made by the veines as its going forwardes is performed only by the arteries And were it not for this continuall circulation of the bloud and this new heating it in its proper cauldron the hart it could not be auoyded but that the extreme partes of the body would soone grow cold and dye For flesh being of it selfe of a cold nature as is apparent in dead flesh and being kept warme meerely by the bloud that bedeweth it and the bloud likewise being of a nature that soone groweth cold and congealeath vnlesse it be preserued in due temper by actuall heate working vpon it how can we imagine that they two singly without any other assistance should keepe one an other warme especially in those partes that are farre distant from the hart by only being together Surely we must allow the bloud which is a substance fitt for motion to haue recourse backe to the hart where only it can be supplyed with new heate and spirits and from thence be driuen out againe by its pulses or stroakes which are his shuttinges And as fast as it flyeth out like a reeking thicke steame which riseth from perfumed water falling vpon a heated panne that which is next before it must fly yet further on to make way for it and new arteriall blould still issuing forth att euery pulse it must still driue on what issued thence the last precedent pulse and that part must presse on what is next before it And thus it fareth with the whole masse of blould which hauing no other course but in the body it must att length runne round and by new vessels which are the veines returne backe vnto the place from whence it issued first and by that time it cometh thither it is growne coole and thicke and needeth a vigorous restauration of spirits and a new rarifying that then it may warme the flesh it passeth againe through without which it would soddainely grow stone cold as is manifest if by tying or cutting the arteries you intercept the blould which is to nourish any part for then
