Section II, Book 3, member 1, chapters 3–6: The admirable effects of sympathy

CHAP. III.

How by relation of Naturall things unto one another, they do, after that a corporall contact or touch is ma[…]e betwixt them, operate wonderfully, and that by a Magneticall concent, or Spirituall continuity, both after a contact or touch is made in the curing of maladies, or wasting his like, by a mutuall operation at an unknown distance.

I Will proceed as I began, from a generall proposition unto diversities of experiences, the which afterwards I will prove feisible and possible, by divers Demonstrative relations.

The Proposition.

It is possible that two Mummyes of opposite condition, that is to say, the one being of a deadly Boreall condition; and the other of a lively and Southern, or aequinoctiall property, may after a corporall contact made betwixt them, operate from one to another a far distance, by a spirituall relation, which is continued between them, as well antipathetically as sympathetically.

Experiment to confirm the same.

An Italian Lord by an accident had his nose cut off, and by the counsel of his Physician made a wound in one of his slaves armes, and clapped his mut[…]lated nose unto it, and so continued it untill a perfect union was made betwixt the flesh of the slave and his Master. Afterwards a gobbit of the slaves flesh which cleaved to the nose, was cut out, and formed into the shape of a nose. The servant's wound was healed up, and for his painfull service during this exploit was manumitted or freed, and with store of money in his purse went unto Naples, which was above a hundred miles from the place where his Master remained, whose adopted flesh on his nose, prospered and did nourish from the veins; so long as the man which was made free, did live. It came to pass that the manumitted person did die at Naples, and thereupon immediatly the adopted flesh unto the Master's nose did decay, and begun to gangrenate, insomuch that if he had not cu[…] it off, it would have marred all the rest and killed him. This relation is known to be so true and certain, that to this day it is famous over all Italy, and in every man's mouth of that Country, and testified by some German Writers and maintained as well by some Scotch as English men, which have been in that Country. By this History therefore we may se[…], that so long as the two bodies which made contact were of one disposition, namely Southern or aequinoctiall, they, though being in body far remote from one another, did operate spiritually, and were present in spirit; that is, they did concur together with the aspect of their sympatheticall beams, and the flesh was spiritually vivified from the slave's lively fountain, even as the grain of Wheat hath […] nourishment, and vivi[…]ieth by the application of the Sun's beams unto it: but when the Southern, or aequinoctiall, or lively property of the bondman's spirit was changed into a deadly Northern and cold disposition, then the vivifying spirit did […]ase to apply any more unto the adopted flesh, and in liew of it, the deadly Northern spirit, did suck or draw away that which the Southern had bestowed upon it, no otherwise then the Northern Frost in the world killeth and draweth out the life of the grain, or seed, or plant, or herb, by his contractive and Boreall property. And for this cause the Gangrene, which is a Northern disea[…]e, did take the borrowed portion of flesh on the nose. Here therefore we see, how the same spirit, altered from a Southern or aequinoctiall, unto a Northern condition, operateth by a contrary, and unnaturall, and depriving means, and that secretly and a far off.

I. A Corollary Demonstration, taken from the Macrocosm[…].

We see in the Wether-glass (of which I spoke before) that between the bolts-head and the place of the water, to wit, in the whole pipe of the Mattras, there is an invisible airy spirit, which though it be not seen of it self, yet doth it operate visibly in effect: Fo[…] if the externall aire be very hot, then it dilateth the aire included in the bolts-head; whereby the water at the other end, is observed to sinck down, though no ocular Agent may be found: but by intellectuall eies we may discern, that it is done through the virtue, and lively Emanation of Sulphurous Light in the aire, by the secret emission of whose beams, the aire is rare[…]ed, and by rarefaction beateth the water downward; and contrariwise, by Northern cold the water is lift up through the contraction of the emitted Spirits; So that we may discern how lively Emanations, and consequently acting and vivifying spirits, are sent forth from the lively and Microcosmicall fountain unto the creatures, which are apt to animate and vivify: but if the fountain become cold and icie, in liew of a Southern acting addition of life, it induceth a mo[…]tifying, and privative substraction, and that as you may perceive in the Wether-glass, by a spirituall concurrence, or rather an invisible, and insensible continuity, which is between both extreams; as you may easily see it demonstrated in the Wether-glass.

II. A Demonstration derived from the Load-stone's property.

If we shall take an ovall Load-stone, namely

[Figure]

and shall divide it in the middle, namely in the aequinoctial about B, C, and then shal expose the part A, B, into his little vessel to flote on the water; and also put the o[…]her half C, D, in another little boat, or vessel in the same water, we shall find that these two halves B, C, being of one aequinoctiall nature, will desire to be joyned again together, and to be reduced into the same continuity it was before; and for that reason, the spirit which is continued between them, though the body be divided, being invisibly united unto both divided portions, doth direct them both, and by an actuall emanation out of each of them, attract, suck, and agglutinate as it were each of them in their naturall position, as they were before.

Application.

By this therefore, the continuation of spirits betwixt the flesh of the forementioned captive at Naples, and that which the master borrowed, remaining elsewhere, is evidently argued and confirmed. And though it may be alleaged, that the Load-stone doth not draw without his orbe, yet I say, that though men do guess at the sensible attraction of weights, yet can they not limit the penetrating action which is between magnetick bodies, as I have proved in my precedent Book, and will hereafter demonstrate it more at large.

A Progression in the foresaid Magneticall Demonstration.

But contrariwise, if we shall attempt to apply the Aequinoctiall, or Southern place of the division in the Load-stone C, unto the pole A, in their barks thus;

[Figure]

the one will fly from the other, and be contrary unto the other; for in so doing, nature will be perverted, and the form of the Stone disturbed. Therefore this flight from one another, or hatred between them, ariseth from the evill position or application of natures, discording in their genuine order, which stir up an intestine war, hatred, or antipathy between the parts, and cause a contrariety or distortion of spirits.

Application.

By which it appeareth, that the aequinoctiall spirit of the late-living captive, being turned northern or Boreal, will in no wise accord with the southern nature of the yet-living adopted or borrowed flesh, which is possessed by the Master, as it did before; but proveth antipatheticall and destructive unto it, that is, it warreth with a contrary property against it, being that now it as fast with-draweth the beams of his spirits from the circumference unto the center, namely, from the flesh lent unto the Master, as, whilst it lived, it did send them after an aequinoctiall manner, forth from the center unto the circumference, namely, from the live fountain in the captive, unto the like in the Master.

III. Demonstration, taken from the Load-stone.

It is evident also, that the Needle touched with the Load-stone, will aspect the Load-stone at any position, whilst the Load-stone is strong and lively; but when the Load-stone is dead, or that he have lost his vertue by the fire, the property of the Needle will also dye.

A second Experiment, confirming the foresaid Proposition.

Against the time that I was to read my publick Anatomy in the College, I had (as our custom is) a certain body of one that was hanged, to be anatomized at my house privately: at which time I was sollicited by Mr. Kellet, the Apothecary, to permit a Gentlewoman, who had a Scirrhous tumor in her belly, to be touched and stroked with the dead man's hand, because experience had taught it to be very efficacious, for the abolishing of the like horrid protuberation in others, as they averred. The Gentlewoman, with her husband and brother, came unto my house, and, as they desired, things were effected. Within a while after the Apothecary, with the Gentlewomans husband, came to give me thanks for that courtesie, assuring me, that it had done his wife good, and taken away the tumorous swelling. Now this doth shew, how the contact of this northern Mummy in the dead mans hand, did cause the southerly growing and vegetating tumour, which did more and more send out its beams from the center to the circumference, to decrease and diminish, and caused it to rot and moulder away, by the centrall continuation or union of the northern spirit in the dead, with that which did vegetate unnaturally in the living, and that at a far distance.

A third Experiment, to expresse the self-same effect.

It is evident, and often approved by common people, that if Warts be rubbed with a piece of fresh beef, and the said beef be conveyed into a field, and buried under the earth, that as the beef wasteth and rotteth in the earth, so will the warts languish and pine away. In like manner it hath been oft observed, that if a piece of bacon be rubbed on warts, and afterwards be nailed on a post against the Sun; as the bacon doth waste and diminish, so also will the warts fade and waste away. Also a dead bodies hand touching warts, they will dye.

Whereby is evidently proved, that as things are sympathetically maintained in their being, that is to say, in their increase or vegetation; so also, by an antipatheticall aspect, or spirituall continuity, between two remote natures, after a corporall contact is made between them, whereof the one is Boreall, the other Southern or Aequinoctiall, the one which touched, will cause it to fade and vanish, after the nature of the toucher. So that as the northern property is an enemy unto life, and southern heat; so by his contact it causeth unnaturally-growing things to fade away by a like property, in changing the vegetating nature of the thing touched, into his decreasing, contracting, and mortifying nature. The experimentall Glass doth teach us, that the action of cold is quite contrary unto that of heat, in one and the same spirit. And Scripture tells us, (if we will not stand unto experience) that the self-same word in his southern property, doth undo and destroy the snow and ice, which it did make in his northern condition.

CHAP. IV.

How certain excrementitious parts, taken from the inform member of the Animal, and transplanted into a vegetable or growing tree, hath a spirituall relation or continuity with the spirit of the sick and impotent member, and consequently of the sick creature. I will for the better method's cause, express in the frontispice of this Chapter a Proposition, as I have done in the precedent.

The Proposition.

THe magneticall force of the spirituall Mummy doth dwell and act, even in the excrementitious or superfluous excrescences, of any member of mans body, after that they are separated from it, and transplanted into some convenient magneticall vegetable or plant; so that by a secret emanation from them, or application unto the beam of the member, from whence they were cut or derived, and consequently by a continued spirituall relation which is had between them, and the body or m[…]mber from whence they were extracted, they are able, by the magneticall plants assistance (whose vegetable nature they borrow and indue) to operate vegetatively upon the same defective dolorous decayed limbe or member at an unlimited distance.

The first Experimentall History.

My Mathematicall Master, excellent for his knowledg in the art of Ingeniery, (remaining with the Cardinall St. George at Rome) did assure me, that if any one had a withered or consumed member, as a dried arm, leg, or foot, or such like, (which Physitians call, An A[…]rcphy of the limbs) and if he did cut from that member, be it foot, or arme, the nails, hair, and scrapings of the skin, and shall pierce a Willow tree, with an anger, or wimble, unto the pith; and after that shall thrust in those pared nails, cut hair, &c. into the hole; and stop the hole close with a peg or pin made of the same wood: observing withall, that this action must be effected, when the Moon is increasing, and the good Planets in such multiplying Signs, as is Gemini, and Saturn, who is a great drier, be depressed, the limbe so wasted, shall by little and little re-vegetate again, even as the Tree (in which the excrements are closed) shall daily increase, grow, and flourish. Also he did aver unto me, that I should find the self-same effect, if I did put those excrements into a hole, made in the root of a Hazel-tree, and close up again the hole with the bark of the same Tree, and afterward cover it with earth; assuring me, that it hath been tried, that as the Tree groweth, so will the member prosper. But above all, he wished me to observe the due order of the heaven, and such secret and proper constellations, as he hath instructed me in; for, without them, the cure or amendment will be the lesse effectuall.

II. Another Magneticall Experiment to confirm the precedent.

Johannes Rhumelius Pharamondus, cureth the Gowt by the very self-same manner of transplantaion in this manner. He cutteth off the hair from the feet, legs, and thighs; and also he pareth off the nails of the feet. Then he maketh a hole in an Oke, even unto the very Center or pith of the body, and pulleth into it the hair and the nails, and afterward he stoppeth up the hole with a peg or pin, framed out of the same Tree; and lastly, he daubeth it without with cow-dung. This Author saith, that by this Magneticall experiment onely he hath cured many. But if it chance (saith he) that the Gowt shall for all this return again, within the space of three months, then it is an Argument that the Oke is insufficient to draw Magnetically: and then he proceedeth thus, namely he boreth another like hole in a second Oke; and after this, he taketh the peeces, of the Oke, which fall out in the boring of the hole, and bruiseth them, and sticheth them in a little bag, and applieh it unto the dolorous or infected member. And this he doth three daies before the New-Moon. Then in that very hour, that the New-Moon is in, he removeth the bag from the part affected, and thrusteth it into the hole of the same Tree, and stoppeth it with a pin of the same wood, as before. And he affirmeth, that by this second practice, when the first hath failed, he hath cur'd many. But if it happen for all this, that the pain doth return within three other moneths; then he cutteth of the hair, and pareth the nails, the second time, and tieth them upon the back of a Crab, or Crab-fish, and so casteth it into the running waters, and the sick will be cured. He concludeth there, that he hath cured many by the first; many others by the first and second; and many, by the first, second, and third Experiments.

A third Experiment tried by the same Author.

The same Author doth verifie, that by this very manner of transplantation, he hath cured many of the Rupture or Hernia; and his practice is after this manner. He taketh a new laid Egge piping hot (as they say) and he rubbeth the Gowty place with it often, but gently: then he taketh away the bark of a good big tree, and with a great auger, he boreth a hole so big, as that the Egge might easily enter into it; then doth he lay on again the bark as before, stopping well the hole thereof with it, and anointing or daubing it with tree wax or caement. All which businesses must be effected in due order and time. And he telleth us, that when the barks of the tree do grow together, then also will the Hernia and rupture also close up. But if it happen that the Hernia be not cured within one moneth, then bore a hole in an Oke, and take the pieces that fall from the hole, bruise them, and stick them in a small bag, and apply it to the grief as is said, about three daies before the new Moon; and then about the hour of the new Moon, put it into the hole, and do in all things as is told you before. He telleth many other observations, as well touching the time, namely if the Hernia's first increase, were in the Moon's increase or decrease; which for brevity sake I here omit: Lastly, if the Hernia be not for all this so dered or glued up, then he boareth a hole in the Oke, and puts in the nail and hair of the Patient's hands and feet; as also the hair of his privy parts, stopping it as is before said: For he affirmeth that when the hole will be grown up, the Hernia will be also closed. There also he sheweth the reason, that he is forced to use more or less of these operations in his cure, according unto the nature of the Hernia, namely to the incipient Hernia one operation will serve; to the inveterate more will be required. And he saith, that in this cure is chiefly to be obserued the time, the measure of the tree, and the depth or profundity of the hole.

Another Experiment by him.

Also he saith, that if we take the nailes of the feet and hands of an Hydropick person, and transplant them on the Crey-fish of the river, and bind them unto the back of her, and cast her into the river, it will cure the Dropsy. Whereby you may plainly observe by approved experience, that the marrow and strengh of the foresaid Proposition, is in every respect confirmed; and again, if we do but burn the nails, and hair, and scrapings of the skin, and take, by an alimbeck without a bottom, the fume of it, we shall find a kind of Balsamick oyle to issue from them, which is very attractive, drying, and agglutinating of wounds. And therefore it appeareth, that there is a Balsamick virtue in these kind of Excrescences; though unto the ignorant they appeare but of little value. But this Magnetick virtue of these Excrementitious parts, may, in some sort, be also demonstrated by the property of the Minerall Load-stone. As for Example.

IV. A Magneticall Demonstration.

We may rightly compare the mass of these superfluous Excrescences, unto a lesser Load-stone, capped with steel: For when it is transplanted into the Plant, it becommeth of a greater force of attraction: For as the Iron being added unto the pole of the Load-stone, though it be but weak; yet it doth fortifie it, and maketh it able to attract a far greater weight; for the Iron giveth it strength. In like manner, if Magnetick Excrescences, be grafted in the body of the Magneticall Tree; then that Tree will suck and draw his like, namely the spirit of defective limbs more strongly unto it; making them to become vegetative, and to increase and grow, which before did pine and wither: For the spirit sucked and continued by dilatation, from the member unto the vegetative nature of the Tree, doth indue the like nature; and doth by a continuity animate the fading spirits in the member, to increase, and vegetate, or prosper in his growth. Now to prove this Magneticall relation, I will produce certain Problems, touching the nature of the Load-stone.

1. Problem.

There is a strong Union in a Load-stone, armed with steel, and heavier weight may be by it taken up, than if it be not armed.

Application.

The reason is, because vis unita est fortior; for the Iron addeth force unto a Load-stone that is weak, as is confirmed by this Problem.

2 Problem.

If there be a thin plate of Steel or Iron held or fastned unto the neather pole of the Load stone, between the Load-stone and the weight; then the Magnet will lift up double, and sometimes decuple, or ten times so much again. And from this practice came the capping or arming of the Adamant with Steel or Iron, after divers manners.

Application.

By the like correlation, If that the animal Magnet be armed with the vegetable power, it will more forcibly attract unto it, spirits from the greater animal Magnet, or rather the animal Iron. Also this Problem following is worthily to be noted.

3. Problem.

Every Body unto the which the lively Mummy of another man is administred or drunk up, doth forthwith become a Magnet, and will be armed to attract his like.

Application.

And therefore the lively Mummy of the decaying member, being in part included in the nailes and hair thereof, and afterward conveyed into the vegetable body, that vegetable body which receiveth them, is made forthwith magneticall, and draweth to it the spirits of the member, and doth impart unto them of his vegetable power. And also the magnetick Mummy in the hair and nails, though of themselves they are but weak, yet are they made more strong and forcible, by being planted in a stronger magnetick vegetable, so that the one doth fortifie and enable the other. This is demonstrated by this Problem.

4 Problem.

A weak Magnet being rubbed at one of the poles of a stronger, will be bettered by it in his vigour and vertue.

Demonstration.

Also, set a Magnet of small force that can be perceived, upon a Load-stone of a good strength and vigour, especially upon the poles, and he will shew a vigour, as if he were as strong as the stronger Stone is, whereunto he is united.

Application.

So by the like reason, we may transplant the superfluous excrescences, in which there appeareth but a small signe of any magnetick vertue, upon a stronger vegetable Magnet, or magneticall plant, and especially in his pith or axil-tree, and he will shew forth a magnetick vigour, equall unto that of the plant, which appeareth in this, namely, because it doth direct by his beams the vegetable power, unto the decayed member. Now that the reference between the tree and the member is caused by a spirituall continuity, it is made plain by this magneticall Problem.

5 Problem.

If a long Iron be conjoyned unto the pole of the Load-stone, and unto the end of this another be laid, and at the end of that a third, and so forward, the Adamant will, by vertue of his beamy emanating spirit, hold them all, or most of them, according unto the vigour thereof, all touching one another, and cleaving together like a linked chain.

Application.

Whereby it is evident, that as the spirit of the Load-stone is continuate, and by his continuity is apt to fasten and joyn bodies in a union, from his center unto his spirituall circumference; even so, by the emanation from the double Magnet united in one, from their center unto the weak line or member, there is caused and ingendred a continuall succession of vegetation in it, by degrees. Now that two Magnets uniting their forces in one, do emit a more vigorous emanation, and are endued with a greater magneticall force, it is proved in the second Problem of the third Demonstration of the second Chapter, before mentioned.

CHAP. VI. Herein is proved, that vegetables contain in themselves magneticall spirits, by means whereof, they do sensibly attract, as well from the Animal, as Vegetable and Mineral kingdom: And it is first expressed by two Propositions, and maintained by divers experimentall Demonstrations.

The first Proposition.

THere is a magneticall vertue, as well in the vegetable, as in the animal and mineral, which doth operate and act attractively, both on his like in the vegetable, and also in the animal and mineral.

The first experimental Demonstration.

The experience hereof is manifold, and by that which hath been related in the precedent Chapter, that the magneticall relation or union which is made between the vegetable and the animal, is sufficiently expressed, and shall be more at large enucleated hereafter. Again, if one that hath an Ague do take the herb called Iberis, namely, a handfull thereof, and put it into either of his shoes, and walketh upon it untill he wax very hot, he will find, that it will draw a great deal of waterish matter downward, and cure the ague. But (saith my Master that taught me) it is not to be cast in the way that man or beast doth pass, for the animal that treadeth on it will be infected, and be aguish. This Christopher Schufzen, a German, did affirm that he had tryed this, and found it to be true.

2 Experience.

Joannes Carfmanus delivereth it for a truth, that warts are taken away out of the hands and other places, by taking of strawes, and cutting the knots in them, and he prepareth in that manner two for every wart, and the strawes must be of a fingers length, which being thus prepared, you must put two sections of the knots in this fashion X upon every wart, so that the nodes do touch directly the warts, and they must strongly be pressed down; and this must be done unto every wart with a double straw, as is already said. Then take those strawes, and dig a hole under a spout or gutter, and cover it with a stone; and you shall find (saith he) that as the strawes do rot, so also will the warts consume away.

3. Experimentall Demonstration.

Mr. Balthazar Wagner saith, that he hath often tryed this magneticall cure, in the inflammation and redness of the eyes most true; he taketh the root of the common Mallow, when the Sun is in the middle of Virgo, and applyeth it backward unto the nuke or nape of the neck, binding it fast thereunto, averring, that it will attract and draw unto it with efficacy, all the cause of the redness.

4. Experimentall Demonstration.

As there is a kind of Load-stone called Evax, which Pliny doth affirm to have a Magneticall power to attract flesh unto it; So also in another place he telleth us that there is another kind of Magnetick Stone, called Sa[…]da, which hath a property to draw wood unto it so strongly, that they cannot be separated from one another, except the wood be cut off from it. But leaving these things as uncredible, I will relate unto you, that mutuall love and sympatheticall affection, which (to my knowledg) hath been found between the Vegetable and the Minerall.

5. Experimentall Demonstration.

There are divers men which do work in the Mines in Germany, of which a couple were imployed about the Silver-Mines in Wales, who do use to gather at a due season, a forked rod of the Hazel-tree, and holding in either hand one of the two twigs in such manner, that the part where the fork beginneth to be perpendicular &c. there is so great a sympathy between this vegetable and the Mine, if it be rich, that the man that marcheth on the hill where the Mine is, and holdeth this Hazelrod in this posture, shall presently perceive the top or perpendicular of the rod to incline violently downward, when the man treadeth on a place, where any Mine is; which is an evident Argument of the Magneticall affection, which is between the one and the other.

6. Experiment.

A man that hath many boils in his body, was counselled (when other things would not cure him) by an old woman, to find out a bramble which groweth out of the earth at both ends, or both ends rooted in the ground: and this man was counselled to creep in his clothes under the bramble backwards, three times, and he was cured; so his boils vanished by little and little, in five or six daies. Mr. Fuller.

2. Proposition.

The singular order, and sympathy or antipathy of the vegetable parts between themselves, is described and typically set forth, by a relation or respect, had between it and the Load-stone; whereby is argued, that the vegetable and minerall, and consequently the animal observe one sympatheticall, or harmonicall proportion, as well in their sympatheticall order, as antipatheticall irregularity in their disorder.

A Problem for the confirmation of the foresaid Proposition.

In all Magneticall things, be they vegetable or minerall, and consequently animall; evermore nature doth tend unto a convenient unity, both in nature and position: and contrariwise, where their parts do not according unto the course of nature, incline unto a conjunction, there happeneth a disturbance, and as it were a diversity between part and part.

Demonstration in the Minerall Magnet.

Take a long Load-stone or Minerall Magnet, and let it be C, D; and let C, be the North Pole, B, and D, the South A; Then divide this long Load-stone in the middle between the two poles, where the aequator passeth, namely in E, F, and E, will be South or aequinoctiall unto the pole D, and F, unto the pole C. As therefore these parts of the Load-stone did respect one another in their entire disposition; So also nature tendeth after their division, to unite them again. And therefore where the division is made, the end E, desireth and coveteth to cleave and adhere unto F. But E. will not be joyned or have any commerce with D, nor yet F, with C, and then one must convert C, unto D, and they will well agree and be combinated together.

[Figure]

For D, turneth to the South as before, and C, to the North. But E, and F, which should be parts naturally conjoyned, and united in the Stone, are in so doing mightily displaced, so that they do not accord and unite together by a materiall union, but they receive their motion and inclination from the form of the Stone; So that the ends of this Stone, whether they are disjoyned or united, do Magnetically tend after one manner unto the poles of the earth, both in its first entire and divided figure, as in the second; and the Magneticall concourse F, E, in the second figure into one body, will be as perfect as that of C, D, even as it was engendered in his vein, and F, E, as the flote in their boat.

Application unto the Vegetable.

This self-same conveniency and inconveniency of the Magneticall Form, which is noted to be in the Minerall Magnet, will also be observed in vegetables: For take a wand or rod of a Willow Tree, or any other Plant, which groweth easily, and let it be A, B, and A is the uppermost part of the rod, and B the lower part,

[Figure]

next unto the root: divide this rod in the middle D, C: I say then, that if the end D, be grafted again in the end C, it will grow. Also if B, be grafted on A, they will be consolidated together, and sprout forth: But if D, be grafted upon A, or C. upon B, they will be at strife, and consequently will never grow, but one of them must needs dye, by reason of the preposterous order and inconvenient position, because that the vegetative force or vigor, which proceedeth after one manner, is now diverted, and compelled or forced into contrary parts.

I will say no more touching this point, but proceed unto the main burthen of these practicall Magneticall Conclusions, with their infallible Demonstration.
