Dr. _MEAD’s_

Short Discourse

EXPLAIN’D.

Many and various are the Opinions about the Design, as well as about the

Meaning and real and true Sense of the short Discourse lately writ by

the Celebrated Dr. _Mead_, for preventing the Plague. The various Turns

of the Heads of different Men, their different Capacities, and the

Sublimity of the Doctor’s Style may, no doubt, occasion all this Variety

in understanding Him and his Book. Some, and if we may judge by the

great Run and Demand for his Book, the greatest Number of the People of

all Ranks expected some _Esculapian_, but easy Rules, whereby they might

govern and conduct their Life against so silent an Enemy as the

Pestilence, which walketh in Darkness. This seems to be more than a

_Conjecture_, because this great Demand ceas’d of a sudden, as the

Plague it self commonly does, after they found the Physician had no hand

in it, or that his Rules were locked up for the Favourites of his

Faculty. And as the People commonly make the best Judgment of Things

after a little Experience, so we find this Judgment of the Town

confirmed, by what his _Friends_, _Adepts_, and other _Officers_, who

only understand or declare what Dr. _Mead_ would have believed; and

accordingly they labour to declare, that the genuine Meaning and Design

of the Celebrated Doctor was, to give a Politick Account, how the Plague

may be staved off by Force of Arms.

I grant this Authority is very cogent; yet, on the other hand, if we

either consider the Title Page of the Book, the great Accurateness and

Veracity of Dr. _Mead_, as well as his signal _Humility_, I must crave

leave to dissent, at this time, from the Reports of these Men, tho’ they

carry his daily and hourly Orders: for how do such Reports sute all

those his known good Qualities, the last more especially. Can any Man

think it consistent with his singular Humility, to teach the Secretary

of State, what has been practised in our own and other Countries for

some hundred of Years: _Quarantines and Pest-Houses_, or if the Doctor

pleases, _Lazarettoes_, are not unknown to English Lawyers, nor English

Ministers. And therefore I think it much the fairest Course, to consider

the Discourse well, because it is short, and from thence to draw the

Sense of its Author.

To do all imaginable Right to Dr. _Mead_, we will begin with the

Title-Page, that nothing material may seem to be neglected. There we

find it is to be a Discourse concerning _Pestilential_ Contagion, and

Methods to prevent it. Turning next to the Dedication, he tells his

Patron that he rather chuses to _put down the principal Heads of

Caution, than a Set of Directions in Form_. This Head he seems to

suggest chiefly to consist in performing Quarantines, and other things

that may be collected from History. The next (Head I suppose) is

concerning the _suppressing Infection here_; which he tells us is _very

different from the Methods taken in former times among us, and from what

they commonly do abroad; but_ (as he very modestly perswades himself)

_will be found agreeable to Reason_. This Account differs very much from

the Rumours and Opinions now prevailing in the World; for we are to be

entertain’d with a preventing Method, as far as Physick and Politicks

extend, and on that Account cannot fail to be very new when finished;

because all former Accounts are very defective, the silent Attacks of

the Pestilence having been hitherto undiscover’d by all former

Physicians. And therefore is there any Person so hard-hearted, or so

stupid, that does not rejoyce and prick up his Ears at those ravishing

Expressions, who does not desire to be instructed in this Method of

preventing this unmerciful Enemy to Mankind. Come on then, and listen to

the Celebrated Dr. _Mead_, who brings Death to Pestilential Contagion;

as he is said to have promis’d while he was composing this Work. But we

will next follow Dr. _Mead_ into the Book it self, where we find that he

thinks it _necessary to premise somewhat in general concerning

Contagion, and the Manner by which it acts_. But alas! we are to meet

with nothing but Disappointments, so soon are we fallen from all our

Hopes and Expectations: Nothing to be found either of _Contagion_, or

the manner of its acting, tho’ the Title of the Book promises it, and

the first entring upon the Discourse declares it to be necessary; This

is the very Soul of the Book, the subject Matter upon which every thing

turns, the Cause of the Plague, and the Indication for preventing and

curing the Plague, are to be drawn out of it.

Besides, the most ancient and best Physicians knew nothing of Contagion,

and far less of _Pestilential Contagion_; Words only brought in by

Physicians in later times, and of Ignorance; and therefore such

suspected Words ought to be well described and defined before they are

made use of; either in discovering the Nature of abstruse Diseases, or

when we are to found Methods of preventing or curing them, upon such

Discoveries.

To leave this Enquiry about Contagion to another Occasion, we will only

observe, that this necessary Article is overseen and neglected by the

Accurate Dr. _Mead_, for Reasons well known to himself, and easily to be

guessed at by every body. It must be acknowledg’d that the Doctor’s way

of writing and inquiring is very singular, the remaining part of his

Book being carried on without Principles, or any known thing with which

his Subject to be explained has any relation.

But, as I have now undertaken to make this short Discourse more

intelligible, I will pursue my Design in Dr. _Mead_’s Method, as far as

that does not obscure the Subject: In that Case I will take the Liberty

to keep the Thread of our Discourse as much in our view is it is

possible. Dr. _Mead_ then having taken leave of _Contagion_, tells us,

that this unknown _Contagion is propagated by three Causes, The Air,

diseased Persons, and Goods transported from infected Places_. What a

propagating Cause may be, shall be left to those that deal in

Metaphysicks, to determine; it matters not what it appears to be, while

the begetting Cause is unknown.

As to Air, he now undertakes to shew us how it becomes _Infectious, and

how it communicates its noxious Quality to other Bodies_. The first, by

the Authority of _Hippocrates_ and _Galen_; but in this he mistakes his

Authors, as he commonly does when they do not come up to his Purpose;

for _Hippocrates_ is thought, by many Authors, not to treat of the

Plague, in this third Book of his Epidemicks; _Galen_, in the Commentary

quoted by Dr. _Mead_, is so far from thinking that _Hippocrates_ was

resolved to give us Cases of the Plague, that he thought quite

otherwise: And for the Truth of this Assertion, take an irrefragable

Authority, _instar omnium_, the learned Dr. _Friend_, who says at the

Remark [1]__Λοιμωδης_, hic non est proprie pestilens & contagiosus,

siquidem in his morbis ab Hippocrate descriptis, nullum est contagii

vestigium: Sed ut Galenus innuit aliud non est, quam _Επιδημια

ὀλέθριος__. And a little after, _sed ipse titulus Galeno paululum

suspectus est_.

[Footnote 1: _Sect. 2._]

We will not insist upon this Sense of _Hippocrates_; but suppose he

there truly treats of the Plague, and that he has observed such a

Temperament of Air to have preceded it, what is this to Contagion and

Infection, which neither _Hippocrates_ nor _Galen_ ever dream’d of.

Besides, _Hippocrates_ calls the Plague a Fever, and in his Opinion

several Affections of Air, to him, and us, perhaps, unknown, produced

Plagues, or Fevers (for these Words are synonimous with him) and the

greatest Part of other Diseases. So that it is manifest from

_Hippocrates_, that this, and many other Alterations of the Air do not

make it _Infectious_.

The following Paragraph is of no Force, after what is now said

concerning _Hippocrates_; the best Historian, that is not a Physician,

is never presumed to go beyond an Account and Relation of Matter of

Fact, as he apprehends it; and so far went the great _Thucydides_, in

relating the Plague of _Athens_. We will rather consider what the Doctor

alledges for strengthning his Conjecture about Contagion. [2]_Stinks of

stagnating Waters, in hot Weather; putrid Exhalations from the Earth;

and above all, the Corruption of dead Carcasses being unburied, have

occasion’d infectious Diseases._ Let us now suppose this Account to be

true, yet his chief Article about Carcasses is absolutely false, as may

be prov’d by one of the best Physicians in any Age; what is all this to

Contagion breeding the Plague: For suppose again, some or all of them

occasion’d _infectious_ Diseases, the Consequence is not, _Ergo_, the

Plague; there being many contagious Diseases that are neither _Plague_

nor Mortal.

[Footnote 2: _Page 3._]

Yet, as if all this were Demonstration, he asserts, That the Plague is

produced by a _Concurrence_ of Causes; _and their first Effect is a

Degree of Stagnation in the Air_, which is follow’d by _Corruption_, and

Putrefaction. It is needless to enter upon this Hint of a new

_Hypothesis_; for if his Machine of Contagion, or Infection, be good,

these are unnecessary. But alas! the celebrated Doctor has, in the

Conclusion, destroy’d the whole Fabrick he had rear’d with so much

Trouble, after he had borrow’d Brick from one, Mortar from another, and

Timber from a third; and only because he became, against Nature and his

own Genius, a Master-Builder. Is a Concurrence of all the supposed

Causes necessary to make a Plague? Then there never was a Plague in the

World; and that because these Causes never all met together: A hopeful

Conclusion! and which at once delivers the World of insufferable Fears,

they hitherto groan’d under, by a vulgar Error; which is now contrary to

Experience, because it is so to Dr. _Mead_’s Reasoning.

_Hippocrates_, on the other Hand, undertakes only to relate the

Constitution of the Year when _Plagues_ and _Fevers_ were very frequent;

he never thought of making any particular Constitution, or the Weather

in it, the Cause of Plagues universally: If he had, Experience should

have shewn the contrary, to which he would have submitted. But not to

enter into any other Constitutions that might happen in _Greece_,

Experience cries loudly against this _Hypothesis_ of Dr. _Mead_; since

we know that _hard_ and _continued frosty_ Weather produces the

Pestilence, most commonly, in our Northern Climates. The Winter 1664,

was a continued Frost all through, as Dr. _Hodges_ informs us; yet the

Plague broke out in the _Christmas_ time, when it was in its _Strength_.

The Plague in _Dantzick_, mention’d by Dr. _Mead_, was in the Winter,

when every thing was bound up with a severe _Frost_; yet so violent was

this Plague, that it bred the _Dunkirk-Fever_ in the Fag-end of it, as

Dr. _Mead_ learnedly conjectures. So that the Pestilence frequently, and

most commonly, happens in a Season very opposite to what the Doctor

finds necessary for breeding _Infection and Corruption_, the

_Fore-runners_ of a Plague.

From all this Account it is manifest, that we hitherto know nothing of

_Contagion_, nor of any Corruption convey’d into Air, which it is to

foment and cherish, to beget or propagate the Pestilence; as also that

this Notion of Contagion taken up and espoused by later Physicians, is

very ill supported by them, and still worse by Dr. _Mead_, who is little

acquainted with their Opinions, so common and obvious in Books of

Physick. And therefore as he has been very unhappy in discovering the

_Change_ in Air that makes it infectious; we will try for better

Success, in his discovering the _Means_, whereby it _communicates its

noxious Quality to other Bodies_.

In order to pursue this Discourse with greater Exactness, it is

necessary to ease our Memory from carrying the different Particulars of

seven Pages, and not to oblige the Reader to take, on trust, what is

writ so long before. It may, perhaps, be useful to Dr. _Mead_ to tell

us[3], that he, lately, left the _Air in a putrid State_; but that is

nothing to us, who are at this present time sensible that the Doctor has

not been able to bring the least Speck of Putrefaction into it. However,

not to balk him in his projected Means, whereby it communicates its

noxious Quality; he desires us to observe, that _Putrefaction is a kind

of Fermentation, and that all Bodies in a Ferment emit a volatile active

Spirit, of Power to agitate, and put into intestine Motions, that is, to

change the Nature of other Fluids, into which it insinuates it self_.

Now we have observed it, we find every Article of this Observation to be

false; for Putrefaction does not always precede Fermentation, nor that

every body in a Ferment emits volatile Spirits, nor that volatile

Spirits have a Power to agitate, or to put into intestine Motions all

Liquors into which they insinuate themselves; and still far less, that

being put into intestine Motions, is to change the Nature of the Fluid

thus put in Motion. What Use the Doctor may have for this Roll of

precarious Assertions, time may tell us: for he has now got the

Master-Key of all Philosophy, even _Fermentation_, into his Hand. By

Fermentation _Stones_, _Metals_, _Plants_, _Animals_, and (if it pleases

him) the _Pestilence_, are generated, and cherished. This makes

Diseases; this cures them; by this we live, by this we die.

[Footnote 3: Page 11.]

Neither does this Machine only answer all our Wants in performing the

greater, but even the smaller feats, as we chance to employ it: for if

we are asked, why _Glow-birds_ shine in the Night? or why _wet Hay_

takes Fire of it self, _&c._ one short Answer is sufficient to all

these, that these great Works are done by _Fermentation_. A Poet in

ancient times, pronounced those Nations happy, that had their rural Gods

growing in their Gardens. But I esteem the Man far more happy, who has

at hand so ready an Answer to every thing: who has got a Machine equally

serviceable on every occasion, the _Philosopher’s Stone_, the _universal

Medicine_, the making a Plague.

Being thus possessed of this useful Machine, he tells us what wonderful

feats he could perform by it, with the Help of _Bellini_’s Doctrine of

Fevers, if he had any time to bestow on so _great a Digression_: for he

could shew us, _how the Alterations made in the Blood will favour

Pestilential Diseases, by rendering the Body obnoxious to them_. Why,

this is the Favour we have waited for in eleven tedious Pages; and if he

writes in English, we may thus be taught how the Blood is affected in

Pestilential Diseases, by laying us a-bed languishing with them. This

would not only be one step towards Contagion, as he artfully begins the

next Paragraph, but might fully inform us of every thing we want to know

concerning it. Why should the Great and Celebrated Dr. _Mead_ call this

a Digression? I wish he would begin thus to digress: but it is now too

late, since he has already digressed from all his Title-Page, and the

half of his Preface. _Contagion_ was dropt at first, and now we find

that _Pestilential Contagion_ has no better Fate. How _preventing_ may

thrive under his Hands, is not hard to guess, since he knows nothing of

what he promises to prevent. These _Methods are very different from

those taken in former times among us, and from what they commonly do

abroad_. Insomuch, that had any body writ in this Method, besides the

Celebrated Doctor, I should have thought him the most ignorant,

impertinent, and self-sufficient Person that ever made a Sale of

Physick.

What Account can he give to Physicians, for thus despising the received

Opinions of _Hippocrates_, and of all their learned and experienc’d

Predecessors, who unanimously declare, that the Plague differs in

nothing from a Fever; or else that a Fever attends every Plague of

Pestilence. And, therefore, in him is all Physick, or else he knows

nothing of it.

Nay, how can he answer it to himself, who in his Manifesto, in the very

next Paragraph, is under an unavoidable Want of a Fever he formerly

neglected. Here he tells us a Tale, That, _the next_ (Step towards

Contagion, and it is not safe to go too near it) _as it seems to me,

proceeds after this Manner_. This kind of introductory Humility has been

very fashionable, of late, among dignify’d Authors; for in advancing a

Proposition, whereof they can bring no Proof, it is not to be thought

how humble, how self-deny’d they are in that Instant; but they _rant_,

_swagger_, and _bully_, if they get their Reader but Three Lines

further. So this celebrated Author, after this humble Cringe, tells us,

_The Blood in all malignant Fevers, especially pestilential ones_ (to be

sure) _at the latter End of the Disease, does, like fermenting Liquors,

throw off a great Quantity of active Particles upon the several Glands

of the Body, particularly upon those of the Mouth and Skin, from which

the Secretions are naturally the most constant and large. These, in

pestilential Cases, although the Air be in a right State, will generally

infect those who are very near to the sick Person; otherwise are soon

dispersed and lost._

The first Part of this Declaration, if my Memory fails me not, is taken

from the Doctor’s elaborate Essay on Poisons; and is brought forth with

all its primitive Elegance, for the present Purpose; but by no means

answers his Want of it: For it does not appear, by _any manner of

Observation_, that the Blood throws off any active Particles at the

latter End of _malignant_ Fevers, _so there is no need to have Recourse

to this_ Supposition. But why upon any Glands? This Expression does not

favour of understanding _Anatomy_. Why upon the Glands of the Mouth?

Surely this Supposition is not of any Use in this Place, however

serviceable it might prove in the mentioned Book, when the _Slabbering_

of a mad Dog was upon the Anvil. Moreover, Is Secretion most constantly

performed at the Glands of the Mouth and of the Skin? Surely not, as

_Sanctorius_ evinces, and is evident from the Doctrine of Secretions,

perfectly well explain’d many Years ago.

Next, let us suppose that this is Standard Physick, as it is quite the

Reverse of it; what mighty matter is to be drawn from it? Why, these

active Particles, tho’ the Air be pure, _will infect those who are very

near to the sick Person; otherwise are soon dispersed and lost_. I hope

there is no harm in the last, and there is no Proof alledg’d for the

former. So that his next Step towards Contagion, does not proceed at

all. I cannot tell how well he manages in the remaining Part of the

Paragraph; and therefore I will only set it in View, that any Person of

a more enlighten’d Understanding than my self may profit by the Doctor’s

own Words. _But when in an evil Disposition of this they meet with these

subtle Parts its Corruption has generated, by uniting with them, they

become much more active and powerful, and likewise more durable and

lasting, so as to form an infectious Matter, capable of conveying the

Mischief to a great Distance from the diseased Body, out of which it was

produced._

Now if Dr. _Mead_’s Narration is to the Purpose, it goes further than he

design’d it should; for how are the active Particles, like fermented

Liquors, thrown out of the Blood in the latter End of malignant Fevers,

and that in so great Plenty, and of so great Energy, that they

themselves had been able to have helped to his next Step of Contagion,

if he had not luckily interposed with a saving Clause, _especially

pestilential ones_, whereby the last would have been deprived of all the

Honour of making Contagion: But what is still worse, Fevers, especially

those that are malignant, are now the chief Article in this Account, and

leave Dr. _Mead_ inexcusable, for not applying Almighty _Fermentation_

to the learned _Bellini_’s Theory of Fevers. And here let it be

observ’d, That those pestilential Steams go no great Length, ’till they

are enabled by the next, unintelligible Means, whereby is formed an

infectious Matter capable of conveying the Mischief to a great Distance.

I hope Doctor _Mead_ understands his last Words; for my Part, I do not,

and by the next Paragraph I find my self still more unqualify’d to

receive his Story of Contagion.

The former Piece of Knowledge is open to those only who are the familiar

Friends of _Attractions_ and _Combinations_ made by Volatile Spirits;

and we who are Strangers to these powerful Words, cannot hope for any

Instruction. But to shew Dr. _Mead_ I have been at true Pains to come

acquainted with them, I find there was Old Attraction, Son of

_Aristotle_; and there is Young Attraction, the great Geometrician; and

a Counterfeit of this in the Works of the celebrated Doctor _Anodyne

Necklace_; which last is mighty like Attraction before us; but as he is

spurious, I must own that I do not find how this Attraction brings me to

a clearer Understanding of the foregoing Paragraph. As to Combination,

whether that of Cooks, or Algebraists, it is of very little or no Use to

me. I must confess, a good Use may be made of these Words; for they will

exchange with _Fermentation_, at any Time that an Author finds himself

disposed to write on a Subject without understanding it.

For Instance, I now intend to make a short Discourse about the

_Philosopher’s Stone_, and a Method for finding it; a very agreeable

Offer to the Publick, when Money is scarce, and Credit very low, through

the great Industry of the ingenious Directors of the _South Sea_. When,

I say, a Man forms to himself this useful Project, _Attraction_ and

_Combination_ does it at once. The Receipt is easy; it is but taking of

_Attraction_, _Circulation_, _Cohobation_, _Concentration_, _a. q. s.

Combination_, _q. s. M._ If this Receipt is duly managed, it will not

only make the _Philosopher’s Stone_, and the grand _Elixir_, but cures

the Plague, and all Diseases, _Curable_ or _Incurable_. But it is to be

noted, that when you would explain how Attraction makes a Plague, you

must be sure due Consideration be had to the Facility and Aptness of

_all kind of Effluvia to be diffused in a warm Air, such as we have

described an infectious one to be_. And, therefore, as the Whole of

Infecting Air is an ill-made Story, supported by Cant and Gibberish, we

will take Leave of it, and his mortify’d Limb together, tho’ it is

brought to give further Light to this strange Stuff.

But, to proceed, the celebrated Doctor smells a Rat; that unless the Air

is allowed a greater Share of shedding Destruction than he has hitherto

allotted it, Matters may go very hard with the whole Doctrine of

_Contagion_; and therefore, notwithstanding its being a Medium for

propagating _Contagion_ only, the Doctor is now willing to pronounce,

with full Power, and for Fear of great Inconveniencies that follow close

at the Heels of the former Doctrine, that _a corrupted State of Air is

_WITHOUT DOUBT NECESSARY_ to give these contagious Atoms their full

Force; for otherwise it is not easy to conceive how the Plague should

ever cease, but with the Destruction_ of all the Inhabitants. Here is a

Devil raised indeed, and he will not be in the least quieted, unless Dr.

_Mead_ will contradict himself, and renounce the half of his Defence,

for the _Pureness_ and _Uncorruptedness_ of Air. And what will not a Man

do for a quiet Life. And even the _English_ Air, that could formerly

kill the greatest Plague, is now without doubt under a State of

Corruption: For if that is not admitted, God have Mercy on all _English_

Men. This is very kind in the Doctor, to take shame to himself for the

Good of his Country.

Conveniency is a pretty Argument, but not very cogent, as we now see;

for this corrupted State of Air is only an Expedient to get rid of a

Pestilence; because by SUPPOSING _an Emendation of the Qualities of the

Air, and restoring of it to a healthy State, capable of dissipating and

suppressing the Malignity_, we put an end to the Plague in an instant.

Mighty fine, and _Meadish_; tho’ he might have put a stop to a Plague at

an easier rate, than the Loss of his Hypothesis; for as the stress of

the Expedient rests upon another fine Word, _supposing_; why, he needed

only to suppose that the whole Magazine of Poison is stopped at once, it

matters not whether that be by an Army, by making it serve a

_Quarantine_, by an _Amulet_, or that the raw Damp is again attracted by

the Sea. I hope due Consideration will be had to this Expedient, in a

new Edition of _the short Discourse_; if so be it has one. This would do

much better than to make another Drawback, which we find is done in the

very next Paragraph; for there, _Infection is not received from the Air

it self, however predisposed, without the Concurrence of something

emitted from infected Persons_. Now if Infection is never receiv’d from

the Air upon any Account whatsoever, it is manifest, that the Air is a

_Medium_, that can neither do Good nor Hurt, and so to the right about,

and the former Allowance is recalled; so that the former Difficulty

still remains, and consequently a Plague once begun in a Country, never

comes to an end, as long as there is a Man alive.

The Principle upon which this Resumption is made, is, because the

Progress of a Pestilence may be stopt at any time, _by strictly

preventing all Intercourse of infected Places with the Neighbourhood_.

He brings as a Proof of this lusty Assertion, what has lately happened

in the raging Plague at _Marseilles_; and alledges, that it has been

effectually confined to that miserable Town, by keeping careful Guard.

But alas! this Argument is out of doors. Happy were it for the People of

_France_ if they had greater Assurance of their Safety, than they can

draw from such vain Promises of Insuring Physicians. And therefore his

Objection remains in full Force, without any Satisfaction being given to

it. I know from whence he took this Difficulty, but he ought to have

been well satisfied that he had brought a full Solution to so powerful

an Argument against all manner of _Contagion_. I will only repeat the

Difficulty, and leave the clearing of it to the Patrons of a Pestilence

being begot by _Contagion_; especially that it is a Step towards Dr.

_Mead_’s next propagating Cause. It is asserted by those who oppose this

_Contagion_, that a Plague is sometimes bred without it, otherwise it

would be perpetual. This Assertion is made good, by considering a

Country where a new Plague is broken out; and ask us, whether it be just

then bred in that Country, or brought thither from elsewhere? If we

grant the first, then indeed adieu to all _Contagion_: If the last, they

bid us name the originary Place, where it was bred: Which would oblige

us to the same Concession as the former. Therefore, say they,

_Contagion_ may _propagate_ but not _begin_ a Plague.

Leaving then Doctor _Mead_ and his _Contagion_ under the Restraint of a

very good Argument, we will consider in the next Place, after what

manner he conveys it to a sound Person, and he _supposes_ the way to be

commonly this: _These contagious Particles—taint the salival Juices_ (or

Spittle) which being _swallowed down into the Stomach, presently fix

their Malignity there_; as appears from _the Nausea and Vomiting, with

which this Distemper often begins its first Attacks_. But all this is

acknowledged to be a Supposition, and not of sufficient Strength to bear

so weighty a Building upon it. _Secondly_, If a Man does nor swallow his

Spittle, or if he gargles his Throat very well before he does swallow

it, there would be no danger from the _Pestilence_; but this slye Plague

should be easily evaded. To what Purpose is this silly Supposition to

bring it into the Stomach, and then to suppose it _fixes its Malignity

there_, because People are often troubled with Vomiting when they are

ill of the Plague. An admirable Way of Reasoning: and as Admiration

begat Philosophy, so Dr. _Mead_’s Philosophy cannot fail of begetting

Admiration: For if the Stomach must needs be the first Place affected by

the Plague, and the Doctor is gone over to _Van Helmont_, cannot he

convey it thither down by the Nose, or even through the Mouth, without

infecting the Spittle.

Dr. _Mead_ is grosly out in his Observation, for the Symptoms of the

_Heart_, our _Strength_ at least, being affected, are previous to his

supposed _Nausea_ and Vomiting; so that he not only ought _to make no

Question_, but to be sure that the _Blood is also more immediately

affected_; as the Multitude of Physicians besides _Van Helmont_ and him

have always believed: But I find his Fancy lies much in odd Conceits. I

know a very honest Man, and a good Observer in Physick, who has fallen

into this very Error in explaining this Symptom of _Vomiting_; but every

Body will acknowledge that his Philosophy is no where the best: And when

this Symptom is truly explained, we shall find that it is a Symptom of a

_Malignant Fever_, as well as of the Plague, without any manner of

Irritation, or of any other Hurt of that Nature, in the Stomach. And

therefore as this Way of conveying the Plague, is a Supposition grounded

upon no manner of Observation (as the Doctor argues in this Paragraph)

so I think there is no need to have recourse to it.

On the other Hand, it might be demonstrated, from the Nature of the

Plague, that it is never, or very rarely, communicated from one Person

to another. At present we will content our selves, to evince this Truth

by a Demonstration of another kind, which is from Observation, or _à

posteriori_, and I will borrow it too from Mr. _Graunt_, in his

Observations on the Bills of Mortality. In his Observations on the

[4]Plague of 1636: He says it lasted 12 Years, in eight whereof there

died 2000 _per Annum_ one with another, and never under 800. The which

shews, _That the Contagion of the Plague depends more upon the

_DISPOSITION_ of the Air, than upon the _EFFLUVIA_ from the Bodies of

Men_. Which also we prove by the sudden jumps which the Plague hath

made, leaping in one Week from 118 to 927; and back again, from 993 to

258; and from thence again, the very next Week, to 852. The which

Effects must surely be rather attributed to _Change_ of the _Air_, than

of the _Constitutions_ of _Mens Bodies_, otherwise than as this depends

upon that.

[Footnote 4: Page 70.]

And therefore as this very common Opinion, about the _Plague_ of

_Pestilence_ passing from one Body into another, is not supported by any

good Reason, far less by the _Suppositions_ and _Innuendo’s_ of Dr.

_Mead_; and is now contrary to the best Observation, most duly and

properly made, we may not doubt to declare, that it very rarely, and

perhaps never, proceeds that Way.

The _Third_ Way Contagion is spread, is, _by Goods transported from

infected Places_. But the Reason of this Fact seems to surmount his

Understanding, and no wonder, for it has already puzzled all other

Philosophers and Physicians, insomuch, that it has driven them into

absurd Notions of _Maggots_, against all Observation. But, before a

Philosopher would spend his Time about this Difficulty, he should be

sure his Fact is indisputably true, for thereby he may save himself much

Trouble and Babling, about a Matter that is false in Fact. However, this

Difficulty may have blunted the Edge of every other Genius, he makes no

doubt to conquer it, and account for it to the World, as he now does in

the following Words: _If, as we have conjectured, the Matter of

Contagion be an active Substance, perhaps in the nature of a Salt,

generated chiefly from the Corruption of a Human Body, it is not hard to

conceive how this may be lodged and preserv’d in soft porous Bodies,

which are kept pressed close together._

Dr. _Mead_ has the readiest Way of getting rid of a Difficulty, of any

Author, tho’ I cannot say it is always the most informing and

perswasive. No Man that understands these Terms, _a Salt_, what it is to

be _soft_ and _porous_, dares keep back his Assent to a Proof _grounded

upon such manifest Observations_, as _Conjectures_, _Perhaps’s_, and

_May-bee’s_; all which are far more ingenious than _Kircher_’s

Maggots-Eggs. However bold this Argument may be, yet if any one will

deny his Matter of _Contagion_ to be an active Substance; or, that it is

a Salt; or, that it rather affects a _soft_ Bed than one that is _hard_,

this _Third_, and last _propagating Cause_, may prove to be no manner of

Cause; and all the World, Merchants especially, cry out against their

Merchandize serving _Quarantine_.

Could Dr. _Mead_ bring all his ordinary Vouchers, I cannot say how far

he might have gone in commanding a Submission from a great Number of Men

to this Article: And therefore if any Person, or Persons, wants fuller

Conviction, let him repair to the _Coffee-Houses_, where they shall have

the Affidavits of ten Physicians, fifteen Apothecaries, and five

Surgeons; and I’ll answer for it, eight in ten shall go, _from

_Batson_’s especially_, fully satisfied with the Truth of the Premises.

But can it be imagined this cunning Doctor would have expos’d his

Character, in this Kind of Argument, to Men of Learning and Virtue. But

here his drooping Spirits revert, and his _Humility_ and _Modesty_

vanish, having at this Stage got rid of the Necessity of Reasoning, the

rest of this inimitable Work being to be carry’d on by Banter and

Assertion; whereby let us take Measure of the Faith and Credulity of the

good People of _England_; for if this passes, _Transubstantiation may be

the next Article he will propose to you_; if it does not, the Doctor and

his Book are discovered at the same Time.

Now we are prepared for all Dr. _Mead_’s _Absurdities_, _Wit_ and

_Banter_, the first Thing he presents us with, _how long a Time Perfumes

hold their Scent, if wrapt up in proper Coverings_; and we must remark,

_That the strongest of those, like the Matter we are treating of (are

mostly animal _Juices_)_ as Musk, Civet, _&c._ (if there be any more.)

And the Substances that keep them the best, are those which receive and

communicate the Plague, as _Furs_, _Feathers_, _Silk_, _Hair_, _Wool_,

_Cotton_, _Flax_, &c. _the greatest part of which are likewise of the

animal Kind_. If the _Pestilence_ is now a _Scent_, yet surely it is a

Noisome one; and if it can be kept, like _Musk_, in its proper Covering,

fourty Days will never deliver us from our fears of it. But all this is

only to amuse us with another new Conceit the Doctor would entertain us

with, that the Matter of the Plague is an _animal Juice_; but pray, good

Doctor, of what Animal? This is not only ridiculous, but overthrows

every Opinion of Physicians that ever was broached about it. But not to

baulk his Wit, this Perfume of the Plague, like Musk, is best kept in

animal Substances; (_Attraction_ would have preceded very decently, for

a more proper Introduction) but is Musk, commonly kept in Furs or

Cotton; if in the last, what Animal is it that yields us Cotton? As for

_Civet_ it is no runaway Merchandize. It is therefore very obvious, that

Men are now passing a Review of their Credulity before Dr. _Mead_ and

the World. But there is another quaint Observation that must not be

neglected, which is, That of all the mentioned Plague-Keepers, Three of

them are animal Substances, and but Two of them of the vegetable Kind.

Mighty fine! and well order’d: But if we turn to another Page of his

[5]Book, we may find this useful Observation contradicted: _But the

greatest Danger from Goods_, is from _Cotton_, _Hemp_, and _Flax_;

_Paper_, or _Books_ (Paper Books surely, or else their covering will

keep them upon an Equality in ballancing Accompts) _Silk_, _Linnen_,

_Wool_, _Feathers_, _Hair_, and _Skins_. In this Account, the vegetable

and animal Plague-Keepers are equal in Number.

[Footnote 5: Page 24.]

What Purposes does this Conceit serve? Why, only to support another

Conceit, _viz._ That animal Substances most vigorously attract animal

Effluvia, or that animal Effluvia run furiously into the Embraces of

animal Substances; which we see by his fine Experiments, is a mere

Fancy. As for _Musk_, _Cotton_ secures it the fastest from running away;

nor do we find that _Feathers_, _Silk_ or _Wool_, are ever put upon that

Service. But supposing every Thing true, and nothing whimsical, that has

been now advanced by the Doctor, we might have expected a further

Discovery; how these Perfumes come to desire their being beded,

cherished, or fomented in soft animal Substances: Is it in Abhorrence of

Annihilation, or by the Love they bear to one another? Or are they kept

together, as the celebrated _Jonathan Wild_ keeps a Felon? In short, is

it by _Sympathy_ or _Antipathy_? For if we are rightly instructed in

these Matters, _these Remarks alone may lead us into_ great and useful

Practices; for if they are skilfully employ’d, they may, perhaps, as I

conjecture, keep the Plague at bay, by being strung up, like Pirates, at

High Water Mark.

For as dull as these Conceits may appear to be; such as never dropp’d

before from any Man in his Senses; yet our Author, who has hitherto

shewn himself Blind in every kind of Argument, is now become so

Sharp-sighted of a sudden, when you are to take his Word for it, that he

boldly asserts, That this _Remark alone_ (of Sympathy and Antipathy)

_may serve to lead us a little into the true Nature of Contagion_. What!

this Nature of Contagion, that is still unknown, after all Dr. _Mead_’s

Endeavours; nay, _Sweats_ and _Labours_, to be drawn at length from

Trifles that bear no Relation to Contagion.

There is no Accounting for this Attempt upon Mankind: The Doctor, I

doubt not, has often made Trial, how far their good Nature could carry

their Belief: but this obtruding on _Scholars_, and _Physicians_ too, is

no less exposing Physick than Physicians. Such Credulity is the very

Reverse of the Incredulity our _Saviour_ complains of, and no less

Marvellous. It is indeed Marvellous, how People were Unbelievers after

the greatest Evidence of Reason and Miracle: Yet we cannot forbear

admiring, if People should swallow all this Trifle and Contradiction,

against all Sense and Reason. We are, indeed, at a loss to explain this

lazy Credulity; and therefore we must have Recourse to the general

_Infection_, that has wrought so strong Delusion, of late Years, all

over _Europe_; when we find Men have become wonderfully Credulous, even

to _Infatuation_. Upon this Supposition a very tolerable good Account

may be given of the mentioned Attempts, for fathoming the Credulity of

Men, let that be found to be ever so deep. If we hove our Lead in the

_South Sea_, we could sound to an hundred Fathom, and bring up yellow

Sand upon the Lead. Some Doctors have often sounded fifty Fathom for

yellow Sand; and Doctor _Anodyne Necklace_ almost as deep for the same.

The _South Sea_ Pilots have now run us a-ground, notwithstanding the

Depth of Water; and Men begin to recover their Senses by the _Surprize_,

_Terriculamenta_ being often found useful to Children: And, I hope, now

they are awake, they will never hereafter subject either their _Lives_

or _Fortunes_ to _Directors_ of any kind.

But as we are, at present, got into the Metaphors of Trade and

Navigation, it has been no small Omission, in every kind of Director,

that they have lately forgot the Genius of _England_; of its being a

Country of Merchants. Had Dr. _Mead_ remember’d the Place of his

Education, he might likewise have saved himself much Labour in

explaining a groundless _Phænomenon_, and spoke more Truth. Was not Dr.

_Mead_ bred, if not born, within the Smoak of _Black Wall_ and

_Wapping_, where both _Church_ and _Conventicle_ have long been a safe

Retreat to foreign Goods, that were not to stand the awful View of a

_Custom House_ Officer? Yet, in all that Time, and ever since, there

have not appeared any Degrees of a Plague. Have not Merchandize been

brought from many Parts of _Turkey_, all which have very deservedly an

ill Name for the _Pestilence_, that very commonly rages among them. And

how comes it to pass, That during this constant, and uninterrupted

Commerce, when _soft_ and _porous_ Goods, the proper _Fomes_, have been

brought from _Smyrna_, _Scanderoon_, _Aleppo_, _Constantinople_, and

other Parts, the Pestilence has never taken a Journey hither, in all

Appearance, those Fifty five Years? In all that Time _Turkey_ Goods have

not served a Quarantine, nor visited any other _Lazaretto_’s, besides

the Companies Cellars; a certain Proof that Goods very seldom, or ever,

bring a Plague into a Country; and oftner find it there than propagate

it.

It is very remarkable, That our Commerce with _Swedeland_, _Poland_, and

other Parts of those Eastern Countries, has been very considerable, when

Plagues have been raging among the mentioned People; and yet we have not

found any Attempts from this silent Enemy on this our happy Island. Nay,

we must more especially observe, that in the Year 1708 and 1709, a most

destructive Pestilence made great Waste in _Dantzig_; and, that there

were some Hundreds of _British_ Ships bound up in Ice, the whole Winter

through; yet we had no other Visit from it, than the supposed fag End of

it, by the _Dunkirk_ Fever; which happen’d four Years after the former

had expir’d. And therefore this Opinion, of a Pestilence being

preserved, and convey’d to distant Places in Goods, as a _Fomes_, is not

sufficiently supported; a particular Care ought to be taken to suppress

such ill-grounded Notions, so prejudicial and hurtful to the People, and

Trade of an Island Country.

The Account Dr. _Hodges_ gives us of the Behaviour of the People of

_London_, after they returned to Town in Winter 1665, is an undeniable

Experiment against a Pestilence being propagated from a _Fomes_, and

almost from one Body to another. He tells us[6], _The Houses which

before were full of the Dead, were now again inhabited by the Living;

and the Shops, which had been most part of the Year shut up, were again

opened, and the People again chearfully went about their wonted Affairs

of Trade and Employ; and even _what is almost beyond belief_, those

Citizens, who were before afraid, even of their Friends and Relations,

would, without fear, venture into the Houses and Rooms where infected

Persons had a little before breathed their Last: Nay, such Comforts did

inspire the languishing People, and such Confidence, that many went into

the _BEDS_, where Persons had died, _EVEN BEFORE THEY WERE COLD_, or

cleansed from the _STENCH_ of the _DISEASE_._ I would gladly know of Dr.

_Mead_, if this, and the mentioned Histories, are Experiments that come

home to the Purpose. In this Account of Dr. _Hodges_, there is no want

of a _Nest_ or _Fomes_, for here is _Wool_, _Linnen_, _Silk_, and,

perhaps, even treacherous _Cotton_ it self, the most secure

Plague-Keeper of all the rest; yet no further Contagion appeared, but

Men eagerly pursued their Business, and thought only how to _repair the

past Mortality_, and that with more than ordinary Success, as Dr.

_Hodges_ tells us in this Place, and his Relation is fully confirm’d by

the Bills of Mortality.

[Footnote 6: Page 27. _Trans._]

It is now very manifest, that Dr. _Mead_ has not given any tolerable, or

probable Account of his _propagating_ Causes; and that every Thing he

has offer’d, in his own Way, is a _Corruption_ of what has been said by

many Physicians. Moreover, he does not yet seem to understand Matters of

Propagation, for he makes his Causes propagate by themselves, contrary

to the common and known Methods of Nature. In this he is not only

unnatural, but I am afraid, that this his Method must be very

_defective_, tho’ it carries his peculiar mark of Excellency, _in

differing from the Methods taken in former Times among us, and from what

they commonly do Abroad_. For formerly here in _England_, and the People

abroad, thought it necessary that the _Seeds_ of the Plague should, like

other Seeds, have a proper _Matrice_ to receive them, to cherish them,

and to rear them up for their proper and peculiar Uses, consonant to

their Nature. They could not see how a Plague could more thrive out of

its proper Ground, than a Grain of _Wheat_, or the Seed of an _Apple_.

So that it was incumbent on Dr. _Mead_, to have shewn the _Disposition_

that may be in every Man to receive, and entertain the Plague, and with

all the Variety in which it palpably affects them. For a Plague has

often laid its devouring Hands on _Children_ and _Young Men_, when it

has spared the _Old_; and, on the contrary, it has proved fatal to

_Age_, when Youth has been excused: Nor has a Pestilence that afflicted

Men hurt _Women_. At other Times Men and Women of all Ages have felt its

Strokes promiscuously, and some have conversed boldly among the Sick of

the Plague with Safety, while others are quickly punished for their

Rashness.

It was very remarkable, that there was not a _British_ Subject, that

wintered in _Dantzig_ in that hard Frost, and Time of Pestilence,

received any Hurt, while Thousands of the Natives fell on their Right

Hand, and Ten Thousands on their Left: This happen’d in the Year 1713.

But it is recorded by [7]_Utenhovius_, that in a cruel Plague that raged

in _Copenhagen_, all Strangers, _English_, _Dutch_, _Germans_, were not

affected with it, when at the same Time it made Havock among the

Inhabitants; yet those Foreigners went freely every where among the

infected People, and into the infected Houses.
