When the Human Brain seems to turn round, the cause is, that some

Vapours do move in a Circular Figure, which causes the Head to be

dizzy; as when a man turns round, not only his Head will be dizzy,

but all the Exterior Parts of his Body; insomuch that some, by often

turning round, will fall down; but if, before they fall, they turn the

contrary way, they will be free from that dizziness: The reason of

which is, That, by turning the contrary way, the Body is brought to the

same posture it was before; as, when a man hath travell'd some way, and

returns the same way back, he returns to the place where first he began

his Journey.

CHAP. V. Of WEAKNESS.

There are many sorts of _Weakness_; some Weakness proceeds from Age;

others, through want of Food; others are occasioned by Oppression;

others, by Disorders and Irregularities; and so many other sorts,

that it would be too tedious to repeat them, could I know them: But,

such sorts of Weakness, as Human Creatures are subject to, after some

Disease or Sickness, are somewhat like Weariness after a Laborious

or over-hard Action; as, when a Man hath run fast, or laboured hard,

he fetches his breath short and thick; and as most of the Sensitive

Actions are by degrees, so is a Returning to Health after Sickness:

but, all Irregularities are Laborious.

CHAP. VI. Of SWOUNDING.

The cause why a Man in _Swound_, is, for a time, as if he were dead;

is, an Irregularity amongst some of the Interior Corporeal Motions,

which causes an Irregularity of the Exterior Corporeal Motions, and so

a general Irregularity; which is the cause that a Man appears as if he

were dead.

But some may say, _A Man in a Swound is void of all Motion_.

I answer: That cannot be: for, if the Man was really dead, yet his

Parts are moving, though they move not according to the property or

nature of a living Man: but, if the Body had not consistent Motions,

and the Parts did not hold together, it would be dissolved in a moment;

and when the Parts do divide, they must divide by Self-motion: but, in

a Man in a Swound, some of his Corporeal Motions are only altered from

the property and nature of a living Man; I say, some of his Corporeal

Motions, not all: Neither do those Motions quite alter from the nature

of a living Man, so as the alterations of the Fundamental Motions do:

but they are so alter'd, as Language may be alter'd, viz. From _Hebrew_

to _Greek, Latin, French, Spanish, English,_ and many others; and

although they are all but Languages, yet they are several Languages

or Speeches; so the alteration of the Corporeal Motions of a Man in

a Swound, is but as the altering of one sort of Language to another;

as put the case, _English_ were the Natural Language or Speech, then

all other Languages were unknown to him that knows no other than his

Natural: So a Man in a Swound is ignorant of those Motions in the

Swound: but, when those Motions return to the Nature of a living Man,

he hath the same knowledg he had before. Thus Human Ignorance, and

Human Knowledg, may be occasioned by the alterations of the Corporeal

Motions.

The truth is, that Swounding and Reviving, is like Forgetfulness and

Remembrance, that is, Alteration and Repetition, or Exchange of the

same Actions.

CHAP. VII. Of Numb and Dead Palsies, or Gangren's.

As for _Numb_ and _Dead Palsies_, they proceed not only from disordered

and Irregular Motions, but from such Figurative Motions as are quite

different from the nature of the Creature: for, though it be natural

for a Man to dye; yet the Figurative Motions of _Death_ are quite

different from the Figurative Motions of Life; so in respect to that

which Man names Life, that which Man names Death, is unnatural: but,

as there are several sorts of that Man names _Life_, or _Lives_; so

there are several sorts of those Corporeal Motions, Man names _Death_:

but, _Dead Palsies_ of some Parts of a Man's Body, are not like those

of a Man when he is, as we say, _quite dead_; for, those are not only

such sorts of Motions that are quite, or absolutely different from

the life of the Man, or such like Creature; but such as dissolve the

whole Frame, or Figure of the Creature: But, the Motions of a _Dead

Palsie_, are not dissolving Motions, although they are different

from the natural living Motions of a Man. The same, in some manner,

are _Numb Palsies_; only the Motions of _Numb Palsies_ are not so

absolutely different from the Natural living Motions; but have more

Irregularities, than perfect Alterations. As for that sort of Numbness

we name _Sleepy Numbness_, it is occasioned through some obstruction

that hinders and stops the Exterior Sensitive Perception. As, when

the Eyes are shut, or blinded, or the Ears stopt, or the Nostrils;

the Sensitive Figurative Motions of those Sensitive Organs, cannot

make Perceptions of Forrein Objects: so, when the Pores of the Flesh,

which are the perceptive Organs of Forrein Touches, are stopt, either

by too heavy burthens or pressings, or tying some Parts so hard, as

to close the Exterior Organs, (_viz_. the Pores) they cannot make

such Perceptions as belong to Touch: but, when those hinderances are

removed, then the Sensitive Perception of Touch, is, in a short time,

as perfect as before.

As for _Gangren's_, although they are somewhat like _Dead Palsies_, yet

they are more like those sorts of dead Corporeal Motions, that dissolve

the Frame and Form of a Creature: for, _Gangren's_ dissolve the Frame

and Form of the Diseased Part; and the like do all those Corporeal

Motions that cause Rottenness, or Parts to divide and separate after a

rotten manner.

CHAP. VIII. Of MADNESS.

There are several sorts of that Distemper named _Madness_; but they

all proceed through the Irregularities, either of the Rational, or

the Sensitive Parts; and sometimes from the Irregularities both

of Sense and Reason: but these Irregularities are not such as are

quite different from the Nature or Property of a Human Creature, but

are only such Irregularities as make false Perceptions of Forrein

Objects, or else make strange Conceptions; or move after the manner

of Dreams in waking-actions; which is not according to the Perception

of present Objects: As for example, The Sensitive Motions of the

Exterior Parts, make several Pictures on the outside of the Organs;

when as no such Object is present; and that is the reason Mad-men see

strange and unusual Sights, hear strange and unusual Sounds, have

strange and unusual Tasts and Touch: but, when the Irregularities are

only amongst the Rational Parts, then those that are so diseased,

have violent Passions, strange Conceptions, wild Fancies, various

Opinions, dangerous Designs, strong Resolutions, broken Memories,

imperfect Remembrances, and the like. But, when both the Sensitive

and Rational are sympathetically disorderly; then the Mad-men will

talk extravagantly, or laugh, sing, sigh, weep, tremble, complain, &c.

without cause.

CHAP. IX. The Sensitive and Rational Parts may be distinctly Mad.

The Senses may be irregularly Mad, and not the Reason; and the Reason

may be irregularly mad, and not the Sense; and, both Sense and Reason

may be both sympathetically mad: And, an evident proof that there is a

Rational and Sensitive Madness, is, That those whose Rational Parts are

Regular, and only some of the Sensitive Irregular, will speak soberly,

and declare to their Friends, how some of their Senses are distemper'd,

and how they see strange and unusual Sights, hear unusual Sounds, smell

unusual Sents, feel unusual Touches, and desire some Remedy for their

Distempers. Also, it may be observed, That sometimes the Rational Parts

are madly distemper'd, and not the Sensitive; as when the Sensitive

Parts make no false Perceptions, but only the Rational; and then only

the Mind is out of order, and is extravagant, and not the Senses: but,

when the Senses and Reason are madly Irregular, then the diseased Man

is that we name, _Outragiously Mad_.

CHAP. X. The Parts of the Head are not only subject to Madness, but

also the other Parts of the Body.

_Madness_ is not only in the Head, but in other Parts of the Body:

As for example, Some will feel unusual Touches in their Hands, and

several other parts of their Body. We may also observe by the several

and strange Postures of Mad-men, that the several Parts of the Body are

madly distemper'd. And it is to be noted, That sometimes some Parts

of the Body are mad, and not the other; as, sometimes only the Eyes,

sometimes only the Ears; and so of the rest of the Organs, and of the

rest of the Parts of the Body; one Part only being mad, and the rest in

good order. Moreover, it is to be noted, That some are not continually

mad, but only mad by fits, or at certain times; and those fits, or

certain times of disorders, proceed from a custom or habit of the

Rational or Sensitive Motions, to move Irregularly at such times; and

a proof that all the Parts are subject to the Distemper of _Madness_,

is, That every part of the Body of those sorts of Mad-men that believe

their Bodies to be Glass, moves in a careful and wary motion, for fear

of breaking in pieces: Neither are the Exterior Parts only subject to

the Distemper of Madness, but the Interior Parts; as may be observed,

when the whole Body will tremble through a mad fear, and the Heart will

beat disorderly, and the Stomack will many times be sick.

CHAP. XI. The Rational and Sensitive Parts of a Human Creature, are apt

to disturb each other.

Although the Rational and Sensitive Corporeal Motions, may, and

do sometimes disagree; yet, for the most part, there is such a

sympathetical Agreement between the Sensitive and Rational Corporeal

Motions of one Society, (viz. of one Creature) as they often disturb

each other: As for example, If the Rational Motions are so irregular,

as to make imaginary Fears, or fearful Imaginations, these fearful

Imaginations cause the Sensitive Corporeal motions, to move according

to the Irregularities of the Rational; which is the cause, in such

fears, that a man seems to see strange and unusual Objects, to hear

strange and unusual Sounds, to smell unusual Sents, to feel unusual

Touches, and to be carried to unusual Places; not that there are such

Objects, but the Irregular Senses make such Pictures in the Sensitive

Organs; and the whole Body may, through the strength of the Irregular

motions, move strangely to unusual places: As for example, A Mad-man,

in a strong mad fit, will be as strong as Ten men; whereas, when the

mad Fit is over, he seems weaker than usually, or regularly, he uses

to be; not that the Self-moving Parts of Nature are capable of being

weaker, or stronger, than naturally they are: but having liberty to

move as they will, they may move stronger, or weaker, swifter or

slower, regularly or irregularly, as they please; nor doth Nature

commonly use Force. But this is to be noted, That there being a general

Agreement amongst the particular Parts, they are more forcible than

when those Parts are divided into Factions and Parties: so that in

a general Irregular Commotion or Action, all the Sensitive Parts of

the Body of a man, agree to move with an extraordinary force, after

an unusual manner; provided it be not different from the property and

nature of their Compositions; that is, not different from the Property

and Nature of a Man. But this is likewise to be noted, That in a

general Agreement, man may have other Properties, than when the whole

Body is governed by Parts, as it is usual when the Body is Regular,

and that every Part moves in his proper Sphere, as I may say, (for

example) the Head, Heart, Lungs, Stomack, Liver, and so the rest, where

each Part doth move in several sorts of Actions. The like may also

may be said of the Parts of the Leggs and Hands, which are different

sorts of Actions; yet all move to the use and benefit of the whole

Body: but, if the Corporeal motions in the Hands, and so in the Leggs,

be irregular, they will not help the rest of the Parts; and so, in

short, the same happens in all the Parts of the Body, whereof some

Parts may be Regular, and others Irregular; and sometimes all may be

Irregular. But, to conclude this Chapter, the Body may have unusual

Force and Properties; as when a man says, He was carried and flung into

a Ditch, or some place distant; and that he was pinch't, and did see

strange sights, heard strange sounds, smelt strange scents; all which

may very well be caused by the Irregular motions, either by a general

Irregularity, or by some particular Irregularity; and the truth is,

The particular Corporeal motions, know not the power of the general,

until they unite by a general Agreement; and sometimes there may be

such Commotions in the Body of a Man, as in a Common-wealth, where many

times there is a general Uproar and Confusion, and none know the Cause,

or who began it. But this is to be noted, That if the Sensitive motions

begin the Disorder, then they cause the Rational to be so disordered,

as they can neither advise wisely, or direct orderly, or perswade

effectually.

CHAP. XII. Of Diseases produced by Conceit.

AS there are numerous sorts of _Diseases_, so there are numerous

manners or ways of the production of Diseases; and those Diseases

that are produced by _Conceit_, are first occasioned by the Rational

Corporeal Figurative Motions: for, though every several Conceit, or

Imagination, is a several Rational Corporeal Figurative Motion; yet,

every Conceit or Imagination doth not produce a Sensitive Effect:

but in those that do produce a Sensitive Effect, it is the Conceit

or Imagination of some sorts of Diseases; but in most of those sorts

that are dangerous to Life, or causes Deformity: The reason is, That

as all the Parts of Nature are Self-knowing, so they are Self-loving:

Also, Regular Societies beget an united Love, by Regular Agreements,

which cause a Rational Fear of a disuniting, or dissolving; and that is

the reason, that upon the perception of such a Disease, the Rational,

through some disorder, figures that Disease; and the Sensitive

Corporeal Motions, take a pattern from the Rational, and so the Disease

is produced.

The Tenth Part.

CHAP. I. Of FEVERS.

Some are of opinion, That all, or, at least, most Diseases, are

accompanied, more or less, with a _Feverous Distemper_: If so, then

we may say, A _Fever_ is the _Fundamental Disease_: but, whether that

Opinion is true, or no, I know not; but I observe, there are many sorts

of Fevers, and so there are of all other Diseases or Distempers: for,

every alteration, or difference, of one and the same kind of Disease,

is a several sort. As for Fevers, I have observed, there are Fevers in

the Blood, or Humours, and not in any of the Vital Parts; and those

are ordinary Burning-Fevers: and there are other sorts of Fevers that

are in the Vital Parts, and all other Parts of the Body, and those are

_Malignant Fevers_; and there are some sorts of Fevers which are in the

Radical Humours, and those are _Hectick Fevers_; and there are other

sorts of Fevers that are in those Parts, which we name the _Spiritous

Parts_. Also, all _Consumptions_ are accompanied with a Feverish

Distemper: but, what the several Figurative Motions are of these

several sorts of Fevers, I cannot tell.

CHAP. II. Of the PLAGUE.

There are Two visible sorts of the Disease named the _Plague_: The

weaker sort is that which produces Swellings, or inflamed or corrupted

Sores, which are accompanied with a Fever. The other sort is that which

is named the _Spotted Plague_. The First sort is sometimes Curable; but

the Second is Incurable; at least, no Remedy as yet hath been found.

The truth is, the _Spotted Plague_ is a _Gangrene_, but is somewhat

different from other sorts of _Gangren's_; for this begins amongst

the Vital Parts, and, by an Infection, spreads to the Extream Parts;

and not only so, but to Forrein Parts; which makes not only a general

Infection amongst all the several Parts of the Body, but the Infection

spreads it self to other Bodies. And whereas other sorts of _Gangren's_

begin outwardly, and pierce inwardly; the _Plaguy Gangrene_ begins

inwardly, and pierces outwardly: so as the difference (as I said) is,

That the ordinary sort of _Gangren's_ infect the next adjoining Parts

of the Body, by moderate degrees; whereas the _Plaguy Gangrene_ infects

not only the adjoining Parts of the same Body, and that suddenly, but

infects Forreign Bodies. Also, the ordinary _Gangren's_ may be stopped

from their Infection, by taking off the Parts infected, or diseased.

But the _Plaguy Gangrene_ can no ways be stopped, because the Vital

Parts cannot be separated from the rest of the Parts, without a total

ruine: besides, it pierces and spreads more suddenly, than Remedies

can be applyed. But, whether there are Applications of Preventions, I

know not; for, those Studies belong more to the _Physicians_, than to a

_Natural Philosopher_. As for the Diseases we name the _Purples_, and

the _Spotted Fever_, they are of the same Kind, or Kindred, although

not of the same sort, as _Measles_, and the _Small-Pox_. But this is to

be noted, That Infection is an act of Imitation: for, one Part cannot

give another Part a Disease, but only that some imitate the same sorts

of Irregular Actions of other Parts; of which some are near adjoining

Imitators, and some occasion a general Mode.

CHAP. III. Of the Small-Pox, and Measles.

The _Small-Pox_ is somewhat like the _Sore-Plague_, not only by being

Infectious, as both sorts of Plagues are; but, by being of a corrupt

Nature, as the Sore-Plague is; only the _Small-Pox_ is innumerable,

or very many small Sores; whereas the _Sore-Plague_ is but one or

two great Sores. Also, the _Small-Pox_ and _Sore-Plague_, are alike

in this, That if they rise and break, or if they fall not flat, but

remain until they be dry and scabbed, the Patient lives: but, if they

fall flat, and neither break, nor are scabbed, the Patient is in

danger to dye. Also, it is to be noted, That this Disease is sometimes

accompanied with a Feverish Distemper; I say, Sometimes, not Always;

and that is the cause that many dye, either with too hot, or too

cooling Applications: for, in a Feverish Distemper, hot Cordials are

Poyson; and when there is no Fever, Cooling Remedies are _Opium_: The

like for letting Blood; for if the Disease be accompanied with a Fever,

and the Fever be not abated by letting Blood, 'tis probable the Fever,

joyned with the Pox, will destroy the Patient: and if no Fever, and

yet loose Blood, the Pox hath not sufficient Moisture to dilate, nor a

sufficient natural Vapour to breathe, or respirate; so as the Life of

the Patient is choaked or

stifled with the contracted Corruptions. As for Measles, though they

are of the same kind, yet not of the same sort; for they are rather

Small Risings, than Corrupted Sores, and so are less dangerous.

CHAP. IV. Of the Intermission of Fevers or Agues.

_Agues_ have several sorts of Distempers, and those quite opposite to

each other, as Cold and Shaking, Hot and Burning, besides Sweating:

Also, there are several times of Intermissions; as some are Every-day

Agues, some Third-day Agues, and some _Quartan_ Agues; and some

Patient may be thus distempered, many times, in the compass of Four

and twenty hours: but those are rather of the Nature of Intermitting

Fevers, than of perfect Agues. Also, in Agues, there is many times a

difference of the Hot and Cold fits: for sometimes the Cold Fits will

be long, and the Hot short; other times, the Hot Fits will be long,

and the Cold Fits short; other times, much of an equal degree: but,

most Intermitting Fevers and Agues, proceed either from ill-digestive

Motions, or from a superfluity of Cold and Hot Motions, or an

Irregularity of the Cold, Hot, Dry; or Moist Motions, where each sort

strives and struggles with each other. But, to make a comparison, Agues

are somewhat like several sorts of Weather, as Freezing and Thawing,

Cloudy or Rainy, or Fair and Sun-shining days: or like the Four Seasons

of the Year, where the Cold Fits are like _Winter_, cold and windy; the

Hot Fits like _Summer_, hot and dry; the Sweating Fits like _Autumn_,

warm and moist; and, when the Fit is past, like the _Spring_. But, to

conclude, the chief Cause of Agues, is, Irregular Digestions, that

make half-concocted Humours; and according as these half-concocted

Humours digest, the Patient hath his Aguish Distempers, where some

are every day, others every second day, some every third day, and

some _Quartans_: but, by reason those half-concocted Humours, are

of several sorts of Humors, some Cold, some Hot, some Cold and Dry,

some Hot and Dry, or Hot and Moist; and those different sorts, raw,

or but half-concocted Humours; they occasion such disorder, not only

by an unnatural manner of Digestion, as not to be either timely, or

regular, by degrees; but, those several sorts of Raw Humours, strive

and struggle with each other for Power or Supremacy: but, according as

those different Raw Humours concoct, the Fits are longer or shorter:

also, according to the quantity of those Raw Humours, and according as

those Humours are a gathering, or breeding, so are the times of those

Fits and Intermissions. But here is to be noted, That some Agues may

be occasioned from some Particular Irregular Digestions; others from a

General Irregular Digestion, some from some obscure Parts, others from

ordinary Humours.

CHAP. V. Of CONSUMPTIONS.

There are many sorts of _Consumptions_; as, some are Consumptions of

the Vital Parts, as the Liver, Lungs, Kidneys, or the like Parts:

Others, a Consumption of the Radical Parts: Others a Consumption of

the Spiritous Parts: Other Consumptions are only of the Flesh; which,

in my opinion, is the only Curable Consumption. But, all Consumptions,

are not only an Alteration, but a Wasting and Dis-uniting of the

Fundamental Parts; only those Consuming Parts do, as it were, steal

away by degrees; and so, by degrees, the Society of a Human Creature is

dissolved.

CHAP. VI. Of DROPSIES.

_Dropsies_ proceed from several Causes; as, some from a decay of some

of the Vital Parts; others through a superfluity of indigested Humours;

some from a supernatural Driness of some Parts; others through a

superfluity of Nourishing Motions; some, through some Obstructions;

others, through an

excess of Moist Dyet: but, all Dropsies proceed not only from Irregular

Motions, but from such a particular Irregularity, as all the Motions

endeavour to be of one Mode, (as I may say) that is, To move after the

manner of those sorts of Motions which are the innate Nature of Water,

and are some sorts of Circular Dilatations: but, by these actions, the

Human Society endeavours to make a Deluge, and to turn from the Nature

of Blood and Flesh, to the Nature of Water.

CHAP. VII. Of SWEATING.

All _Sweating-Diseases_ are somewhat of the nature of Dropsies; but

they are (at least, seem to be) more Exterior, than Interior Dropsies:

but, though there be Sweating-Diseases which are Irregular; yet,

Regular Sweating is as proper as Regular Breathing; and so healthful,

that Sweating extraordinary, in some Diseases, occasions a Cure: for,

Sweating is a sort of Purging; so that the evacuation of Sweat, through

the Pores, is as necessary as other sorts of evacuation, as Breathing,

Urine, Siege, Spitting, Purging through the Nose, and the like. But,

Excess of Sweating, is like other sorts of Fluxes, of which, some will

scowr to death; others vomit to death; and others the like Fluxes will

occasion

death; the like is of Sweating: so that the _Sweating-Sickness_ is

but like a _Fluxive-Sickness_. But, as I said, Regular Sweating is as

necessary as other ordinary Evacuations: and as some are apt to be

restringent, others laxative; and sometimes one and the same Man will

be laxative, other times, costive; so are Men concerning Sweating: and

as some Men take Medicines to purge by Stool, or Vomits, or Urine; so

they take Medicines to purge by Sweating. And, as Man hath several

sorts of Excremental Humours, so, several sorts of Sweats; as, Clammy

Sweats, Cold Sweats, Hot Sweats, and Faint Sweats: and, as all Excess

of other sorts of Purgings, causes a Man to be weak and faint; so doth

Sweating.
