And here it may be worth our while to take a Review of the Variety and

Multitude of our Riches. For Trees and Herbs do not only ſerve us for

Food, they in their delicious Fruits, theſe in their Seeds, Leaves and

Roots; but Herbs moreover furniſh us with Phyſick, and Trees with

Timber for our Houſes and Ships. Flax, by the means of thoſe two uſeful

Arts of Spinning and Weaving, affords us Clothing. Of Hemp or Matweed

we twiſt our ſelves Thread and ſmall Ropes, the former of which we

employ in Sails and Nets, the latter in making larger Ropes for Maſts

and Anchors. With the ſweet Smells and [The Advantages we reap from

Herbs and Animals.] beauteous Colours of Flowers we feaſt our Senſes:

and even thoſe of them, that offend our Noſtrils, or are miſchievous to

our Bodies, are ſeldom without excellent Uſes: or were made perhaps by

Nature as a Foil to ſet off, and make us the more value the Good by

comparing them with theſe. What vaſt Advantages and Profit do we reap

from the Animals? The Sheep give us Clothing, and the Cows afford us

Milk: and both of them their Fleſh for our Suſtenance. Aſſes, Camels,

and Horſes do, what if we wanted them we muſt do our ſelves, carry our

Burdens; and the laſt of them we make uſe of, either themſelves to

carry us, or in our Coaches to draw us. In which we have ſo excellent,

ſo uſeful an Invention of Wheels, that I can’t ſuppoſe the Planets to

enjoy Society and all its Conſequences, and be without them. Whether

they are Pythagoreans there, or feed upon Fleſh as we do, I dare not

affirm any Thing. Tho’ it ſeems to be allowed Men to feed upon

whatſoever may afford them Nouriſhment, either on Land, or in Water,

upon Herbs, and Pomes, Milk, Eggs, Honey, Fiſh, and no leſs upon the

Fleſh of many Birds and Beaſts. But it is a ſurpriſing thing! that a

rational Creature ſhould live upon the Ruin and Deſtruction of ſuch a

number of other his Fellow-Creatures! And yet it does not ſeem at all

unnatural, ſince not only he, but even Lions, Wolves, and other

ravenous Beaſts, prey upon Flocks of other harmleſs Things, and make

mere Fodder of them; as Eagles do of Pidgeons and Hares; and large Fiſh

of the helpleſs little ones. We have different ſorts of Dogs for

Hunting, and what our own Legs cannot, that their Noſe and Legs can

help us to. But the Uſe and Profit of Herbs and Animals are not the

only Things they are good for, but they raiſe our Delight and

Admiration when we conſider their various Forms and Natures, and

enquire into all their different ways of Generation: Things ſo

infinitely multifarious, and ſo delightfully amazing, that the Books of

natural Philoſophers are deſervedly filled with their Encomiums. For

even in the very Inſects, who can but admire the ſix-corner’d Cells of

the Bees, or the artificial Web of a Spider, or the fine Bag of a

Silk-worm, which laſt affords us, with the Help of incredible Induſtry,

even Shiploads of ſoft delicate Clothing. This is a ſhort Summary of

thoſe many profitable Advantages the animal and herbal World ſerve us

with.

But this is not all. The Bowels of the Earth likewiſe contribute much

to Man’s Happineſs. For what Art and Cunning does he employ in finding,

in digging, in trying Metals, and in melting, refining, and tempering

them? [And from Metals.] What Skill and Nicety in beating, drawing or

diſſolving Gold, ſo as with inconſiderable Changes to make every Thing

he pleaſes put on that noble Luſtre? Of how many and admirable Uſes is

Iron? and how ignorant in all Mechanical Knowledge were thoſe Nations

that were not acquainted with it, ſo as to have no other Arms but Bows,

Clubs, and Spears, made of Wood. There’s one Thing indeed we have,

which it’s a Queſtion whether it has done more harm or good, and that

is Gun-powder made of Nitre and Brimſtone. At firſt indeed it ſeem’d as

if we had got a more ſecure Defenſe than former Ages againſt all

Aſſaults, and could eaſily guard our Towns, by the wonderful Strength

of that Invention, againſt all hoſtile Invaſions: but now we find it

has rather encouraged them, and at the ſame time been no ſmall Occaſion

of the Decay of Valour, by rendring it and Strength almoſt uſeleſs in

War. Had the Grecian Emperor who ſaid, Virtue was ruin’d only when

Slings and Rams firſt came into uſe, liv’d in our Days, he might well

have complain’d; eſpecially of Bombs, againſt which neither Art nor

Nature is of ſufficient Proof: but which lays every Thing, Caſtles and

Towers, be they never ſo ſtrong, even with the Ground. If for nothing

elſe, yet upon this one account, I think we had better have been

without the Diſcovery. Yet, when we were talking of our Diſcoveries, it

was not to be paſs’d over, for the Planets too may have their

miſchievous as well as uſeful Inventions.

We are happier in the Uſes for which the Air and Water ſerves us; both

of which helps us in our Navigation, and furniſhes us with a Strength

ſufficient, without any Labour of our own, to turn round our Mills and

Engines; Things which are of uſe to us in ſo many different

Employments. For with them we grind our Corn, and ſqueeze out our Oil;

with them we cut Wood, and mill Cloth, and with them we beat our Stuff

for Paper. An incomparable Invention! Where the naſtieſt uſeleſs Scraps

of Linen are made to produce fine white Sheets. To theſe we may add the

late diſcovery of Printing, which not only preſerves from Death Arts

and Knowledge, but makes them much eaſier to be attained than before.

Nor muſt we forget the Arts of Engraving and Painting, which from mean

Beginnings have improved to that Excellence, that nothing that ever

ſprung from the Wit of Man can claim Pre-eminence to them. Nor is the

way of melting and blowing Glaſſes, and of poliſhing and ſpreading

Quick-ſilver over Looking-Glaſſes, unworthy of being mentioned, nor

above all, the admirable uſes that Glaſſes have been put to in natural

Knowledge, ſince the Invention of the Teleſcope and Microſcope. And no

leſs nice and fine is the Art of making Clocks, ſome of which are ſo

ſmall as to be no weight to the Bearer; and others ſo exact as to

meaſure out the Time in as ſmall Portions as any one can deſire: the

Improvement of both which the World owes to my [1]Inventions.

[From the diſcoveries of our Age.]

I might add much here of the late Diſcoveries, moſt of them of this

Age, which have been made in all ſorts of Natural Knowledge as well as

in Geometry and Aſtronomy, as of the Weight and Spring of the Air, of

the Chymical Experiments that have ſhown us a way of making Liquors

that ſhall ſhine in the Dark, and with gentle moving ſhall burn of

themſelves. I might mention the Circulation of the Blood through the

Veins and Arteries, which was underſtood indeed before; but now, by the

help of the Microſcope, has an ocular demonſtration in the Tails of

ſome Fiſhes: of the Generation of Animals, which now is found to be

performed no otherwiſe than by the Seed of one of the ſame kind; and

that in the Seed of the Male are diſcover’d, by the help of Glaſſes,

Millions of ſprightly little Animals, which it’s probable are the very

Offspring of the Animals themſelves: a ſurpriſing thing, and never

before now known!

[The Planets have, tho’ not theſe ſame, yet as uſeful Inventions.]

Thus have I put together all theſe late Diſcoveries of our Earth: and

now, tho’ perhaps ſome of them may be common to the Planetary

Inhabitants with us, yet that they ſhould have all of them is not

credible. But then they may have ſomewhat to make up that Defect,

others as good and as uſeful, and as wonderful, that we want. We have

allow’d that they may have rational Creatures among them, and

Geometricians, and Muſicians: We have prov’d that they live in

Societies, have Hands and Feet, are guarded with Houſes and Walls:

Wherefore if a Man could be carried thither by ſome powerful Genius,

ſome Mercury, I don’t doubt ’twould be a very curious ſight, curious

beyond all Imagination, to ſee the odd ways, and the unuſual manner of

their ſetting about any thing, and their ſtrange methods of living. But

ſince there’s no hopes of our going ſuch a Journey, we muſt be

contented with what’s in our Power: we may ſuppoſe our ſelves there,

and inquire as far as we can into the Aſtronomy of each Planet, and ſee

in what manner the Heavens preſent themſelves to their Inhabitants. We

ſhall make ſome Obſervations of the Eminence of each of them, in

reſpect of their Magnitude, and number of Moons they have to wait on

them; and ſhall propoſe a new Method of coming to ſome Knowledge of the

incredible diſtance of the ſix’d Stars. But firſt after this long and

deep Thoughtfulneſs we will give our ſelves a little Reſt, and ſo put

an end to this Book.

New Conjectures concerning the

Planetary Worlds.

BOOK the Second.

’Twas a pretty many Years ago that I chanc’d to light upon Athanaſius

Kircher’s Book, call’d The Ecſtatick Journey, which treats of the

nature of the Stars, and of the Things that are to be found in the

Superficies of the Planets: I wondered to ſee nothing there of what I

had often thought not improbable, but quite other Things, nothing but a

Heap of idle unreaſonable Stuff: which I was the more confirm’d in,

when, after the writing of the former part, I ran over the Book again.

And I thought mine were very conſiderable and weighty Matters if

compar’d with Kircher’s. That other People may be ſatisfied in this,

and ſee how vainly thoſe, who caſt off the only Foundations of

Probability in ſuch Matters, which we have all the way made uſe of,

pretend to philoſophize in this caſe, I think it will not be beſide the

Purpoſe to beſtow ſome few Reflections upon that Book.

[Kircher’s Journey in Ecſtacy examin’d.]

That ingenious Man ſuppoſing himſelf carried by ſome Angel thro’ the

vaſt Spaces of Heaven, and round the Stars, tells us, he ſaw a great

many things, ſome of which he had out of the Books of Aſtronomers, the

reſt are the Product of his own Fancy and Thoughts. But, before he

enters upon his Journey, he lays down theſe two Things as certain; that

no Motion muſt be allowed the Earth, and that God has made nothing in

the Planets, no not ſo much as Herbs, which has either Life or Senſe in

it. Leaving then the Syſtem of Copernicus, he chuſes Tycho for his

Guide. But when he ſuppoſes all the fix’d Stars to be Suns, and round

each of them places their Planets, here (againſt his Will I ſuppoſe) he

has unawares made an infinite number of Copernican Syſtems. All which,

beſide their own Motion, he abſurdly makes to be carried, with an

incredible ſwiftneſs, in twenty four Hours round the Earth. Since moſt

of theſe Worlds are out of the Reach of any Man’s ſight, as he owns

they are, I cannot think for what purpoſe he makes ſo many Suns to

ſhine upon deſolate Lands (like our Earth in every thing, he ſays, only

that they have neither Plants nor Animals) where there’s no one to whom

they ſhould give light. And from hence he ſtill falls into more and

more Abſurdities. And becauſe he could find no other uſe of the

Planets, even in our Syſtem, he is forc’d to beg Help of the

Aſtrologers; and would have all thoſe vaſt Bodies made upon no other

account than that the whole Univerſe might be preſerved and continue

ſecure by their means, and that they might govern the Mind of Man by

their various and regular Influences. Accordingly, to gratify

Aſtrology, he ſays that Venus was the moſt pleaſant Place, every thing

fine and handſome, its Light gentle, its Waters ſweet and purling, and

it ſelf beſet all about with ſhining Chryſtals. In Jupiter he found

wholeſome and ſweet Gales, delicate Waters, and a Land ſhining like

Silver. For from theſe two Planets it ſeems, Men have all that is happy

and healthful poured down upon them; and all that renders them handſome

and lovely, wiſe and grave, is owing to their Influences. Mercury had I

don’t know what Airineſs and Briskneſs in it; whence Men derive, when

they are firſt born, all their Wit and Cunning. Mars was nothing but

infernal, ſtinking, black Flames and Smoke: and Saturn was all

melancholy, dreadful, naſty, and dark: for theſe are the Planets (I

don’t know why, but all Fortune-tellers hate them) that bring all the

Plagues and Miſchiefs that we feel upon us, and would exerciſe their

Spite ſtill more, unleſs they were ſometimes mitigated and corrected by

the benign and kind Influences of the other Planets. All this and ſuch

like Stuff his Genius teaches him. Which he makes give a ſerious Anſwer

to this idle Queſtion, Whether a Jew or Heathen could be duly and

rightly baptized in the Waters of Venus? Of him too he learns that the

Heaven of the fix’d Stars is not made of ſolid Matter, but of a thin

fluid, wherein an innumerable company of Stars and Suns lie floating

here and there, not chain’d down to any Place, (thus far he’s in the

right) and deſcribing in the Space of a Day theſe prodigious Circles

round the Earth. He forgets here, if there were ſuch a Motion, with

what an incredible ſwiftneſs they would fly off from every part of

their Orbits. But I ſuppoſe the Intelligences that he has plac’d in

them are to take care of that, thoſe Angels that preſide over, and

regulate their Motions. And in that he follows a company of Doctors

that harbour’d that idle fancy of Ariſtotle upon no Account or

Conſideration. But Copernicus has freed thoſe Intelligences of all that

Labour and Trouble, only by bringing in the Motion of the Earth: which,

if upon no other Account, every one that is not blind purpoſely, muſt

own to be neceſſary upon this. I dare ſay Kircher, if he had dar’d

freely to ſpeak his Mind, could have afforded us better ſort of Things

than theſe. But when he could not have that liberty, I think he might

as well have let the whole Matter alone. But enough of this; let’s have

have done with this famous Author: And now that we have ventur’d to

place Spectators in the Planets, let us examine each of them, and ſee

what their Years, Days, and Aſtronomy are.

[The Syſtem of the Planets in Mercury.]

To begin with the innermoſt and neareſt the Sun: We know that Mercury

is three times nearer that vaſt Body of Light than we are. Whence it

follows that they ſee him three times bigger, and feel him nine times

hotter than we do. Such a degree of Heat would be intolerable to us,

and ſet afire all our dry’d Herbs, our Hay and Straw that we uſe. And

yet there is no doubt but that the Animals there, are made of ſuch a

Temper, as to be but moderately warm, and the Plants ſuch as to be able

to endure the Heat. The Inhabitants of Mercury, it’s likely, have the

ſame opinion of us that we have of Saturn, that we muſt be intolerably

cold, and have little or no Light, we are ſo far from the Sun. There’s

reaſon to doubt, whether the Inhabitants of Mercury, tho’ they live ſo

much nearer the Sun, the Fountain of Life and Vigour, are much more

airy and ingenious than we. For if we may gueſs at them by what we ſee

here, we ſhall not be obliged to grant it. The Inhabitants of Africa

and Braſil, that have got for their Share the hotteſt Places in the

Earth, being neither ſo wiſe nor ſo induſtrious as thoſe that belong to

colder and more temperate Climates; they have ſcarce any Arts or

Knowledge among them; and thoſe of them that live upon the very Shore,

underſtand little or no Navigation. Nor can I be willing to make all

that vaſt number that muſt inhabit thoſe two large Planets, Jupiter and

Saturn, and have ſuch noble Attendance, mere dull Blockheads, or

without as much Wit as our ſelves, tho’ they are ſo far more diſtant

from the Sun. The Aſtronomy of thoſe that live in Mercury, and the

appearance of the Planets to them, oppoſite at certain times to the

Sun, may be eaſily conceived by the Scheme of the Copernican Syſtem in

the former Part. At the times of theſe Oppoſitions Venus and the Earth

muſt needs appear very bright and large to them. For if Venus ſhines ſo

gloriouſly to us when ſhe is new and horned, ſhe muſt neceſſarily in

oppoſition to the Sun, when ſhe is full, be at leaſt ſix or ſeven times

larger, and a great deal nearer to the Inhabitants of Mercury, and

afford them Light ſo ſtrong and bright, that they have no reaſon to

complain of their want of a Moon. What the Length of their Days are, or

whether they have different Seaſons in the Year, is not yet diſcovered,

becauſe we have not yet been able to obſerve whether his Axis have any

inclination to his Orbit, or what Time he ſpends in his diurnal

Revolution about his own Axis. And yet ſeeing Mars, the Earth, Jupiter

and Saturn, have certainly ſuch Succeſſions, there’s no reaſon to doubt

but that he has his Days and Nights as well as they. But his Year is

ſcarce the fourth part ſo long as ours.

The Inhabitants of Venus have much the ſame Face of Things as thoſe in

Mercury, only they never ſee him in oppoſition to the Sun, which is

occaſioned by his never removing above 38 degrees, or thereabouts, from

it. The Sun appears to them larger by half in his Diameter, and above

twice in his Circumference, than to us: and by conſequence affords them

but twice as much Light and Heat, ſo that they are nearer our

Temperature than Mercury. Their Year is compleated in ſeven and a half

of our Months. In the Night our Earth, when ’tis on the other ſide of

the Sun from Venus, muſt needs ſeem much larger and lighter to Venus

than ſhe doth ever to us; and then they may eaſily ſee, if their Eyes

be not weaker than ours, our conſtant Attendant the Moon. I have often

wonder’d that when I have view’d Venus when ſhe is neareſt to the

Earth, and reſembled an Half-moon, juſt beginning to have ſomething

like Horns, through a Teleſcope of 45 or 60 Foot long, ſhe always

appeared to me all over equally lucid, that I can’t ſay I obſerved ſo

much as one Spot in her, tho’ in Jupiter and Mars, which ſeem much leſs

to us, they are very plainly perceiv’d. For if Venus had any ſuch Thing

as Sea and Land, the former muſt neceſſarily ſhow much more obſcure

than the other, as anyone may ſatisfy himſelf, that from a very high

Mountain will but look down upon our Earth. I thought that perhaps the

too brisk Light of Venus might be the occaſion of this equal

appearance; but when I uſed an Eye-glaſs that was ſmok’d for the

Purpoſe, it was ſtill the ſame Thing. What then, has Venus no Sea, or

do the Waters there reflect the Light more than ours do, or their Land

leſs? Or rather (which is moſt probable in my Opinion) is not all that

Light we ſee reflected from an Atmoſphere ſurrounding Venus, which

being thicker and more ſolid than that in Mars or Jupiter, hinders our

ſeeing any thing of the Globe it ſelf, and is at the ſame time capable

of ſending back the Rays that it receives from the Sun? For it is

certain that if we looked on the Earth from the outſide of the

Atmoſphere, we ſhould not perceive ſuch a difference as we do from a

Mountain; but by reaſon of the interpoſed Atmoſphere, we ſhould obſerve

very little Diſparity between Sea and Land. ’Tis the ſame Thing that

hinders us from ſeeing the Spots in the Moon as plain in the Day as in

the Night, becauſe the Vapours that ſurround the Earth being then

enlighten’d by the Rays of the Sun, are an Impediment to our Proſpect.

[In Mars.]

But Mars, as I ſaid before, has ſome Parts of him darker than other

ſome. By the conſtant Returns of which his Nights and Days have been

found to be of about the ſame length with ours. But the Inhabitants

have no perceivable Difference between Summer and Winter, the Axis of

that Planet having very little or no Inclination to his Orbit, as has

been diſcover’d by the Motion of his Spots. Our Earth muſt appear to

them almoſt as Venus doth to us, and by the Help of a Teleſcope will be

found to have its Wane, Increaſe, and Full, like the Moon: and never to

remove from the Sun above 48 Degrees, by whoſe Diſcovery they ſee it,

as well as Mercury and Venus, ſometimes paſs over the Sun’s Disk. They

as ſeldom ſee Venus as we do Mercury. I am apt to believe, that the

Land in Mars is of a blacker Colour than that of Jupiter or the Moon,

which is the reaſon of his appearing of a Copper Colour, and his

reflecting a weaker Light than is proportionable to his diſtance from

the Sun. His Body, as I obſerved before, tho’ farther from the Sun, is

leſs than Venus. Nor has he any Moon to wait upon him, and in that, as

well as Mercury and Venus, he muſt be acknowledged inferiour to the

Earth. His Light and Heat is twice, and ſometimes three times leſs than

ours, to which I ſuppoſe the Conſtitution of his Inhabitants is

anſwerable.

[Jupiter and Saturn the moſt eminent of the Planets both for bigneſs

and attendants.]

If our Earth can claim pre-eminence of the fore-mention’d Planets, for

having a Moon to attend upon it, (for its Magnitude can make but a

ſmall difference) how much Superiour muſt Jupiter and Saturn be to

thoſe three and the Earth alſo? For whether we conſider their Bulk, in

which they far exceed all the others, or the Number of Moons that wait

upon them, it’s very probable that they are the chief, the primary

Planets in our Syſtem, in compariſon with which the other four are

nothing, and ſcarce worth mentioning. For the eaſier Conception of

their vaſt Diſparity, I have thought fit to add a Scheme of our Earth,

with the Moon’s Orbit, and the Globe of the Moon itſelf, and the

Syſtems of [Fig. 3.] Jupiter and Saturn, where I have drawn every thing

as near the true Proportion as poſſible. Jupiter you ſee is adorned

with four, and Saturn with five Moons, all placed in their reſpective

Orbits. The Moons about Jupiter we owe to Galilæo, ’tis well known: and

any one may imagine he was in no ſmall Rapture at the Diſcovery. The

outermoſt but one, and brighteſt of Saturn’s, it chanc’d to be my lot,

with a Teleſcope not above 12 foot long, to have the firſt ſight of in

the Year 1655. The reſt we may thank the induſtrious Caſſini for, who

uſed the Glaſſes of Joſ. Campanus’s grinding, firſt of 36, and

afterwards of 136 foot long. He has often, and particularly in the Year

1672, ſhew’d me the Third and Fifth. The Firſt and Second he gave me

notice of by Letters in the Year 1684; but they are ſcarce ever to be

ſeen, and I can’t poſitively ſay, I had ever that Happineſs; but am as

ſatisfied that they are there, as if I had; not in the leaſt ſuſpecting

the Credit of that worthy Man. Nay, I am afraid there are One or Two

more ſtill behind, and not without reaſon. For between the Fourth and

Fifth there’s a Diſtance not at all proportionable to that between all

the others: Here, for ought I know, there may be a Sixth; or perhaps

there may be another without the Fifth that may yet have eſcaped us:

for we can never ſee the Fifth but in that part of his Orbit, which is

towards the Weſt: for which we ſhall give you a very good reaſon.

Perhaps when Saturn comes into the Northern Signs, and is at a good

height from the Horizon (for at the writing of this he is at his

loweſt) you may happen to make ſome new Diſcoveries, good Brother, if

you would but make uſe of your two Teleſcopes of 170 and 210 Foot long;

the longeſt, and the beſt I believe now in the World. For tho’ we have

not yet had an opportunity of obſerving the Heavens with them (as well

by reaſon of their Unwieldineſs, as for the Interruption of our Studies

by your Abſence) yet I am ſatisfied of their Goodneſs by our trial of

them one Night, in reading a Letter at a vaſt diſtance by the Help of a

Light. I cannot but think of thoſe times with Pleaſure, and of our

diverting Labour in poliſhing and preparing ſuch Glaſſes, in inventing

new Methods and Engines, and always puſhing forward to ſtill greater

and greater Things. But to return to the Figures, of which there

remains ſomething further to be ſaid.

[The proportion of the Diameter of Jupiter, and of the Orbs of his

Satellites, to the Orbit of the Moon round the Earth.]

I have there made the Diameter of Jupiter about two third parts of our

diſtance from the Moon: for the Diameter of Jupiter is above twenty

times bigger than that of the Earth; which is about a thirtieth part of

the Moon’s diſtance. The Orbit of the outermoſt of Jupiter’s Satellites

is to that of the Moon round the Earth, as 8 and ½ is to 1. And each of

theſe Moons, by the Shadow they make upon Jupiter, cannot be leſs than

our Earth. Their [The Periods of Jupiter’s Moons.] Periods, that I may

not omit them, are according to Caſſini’s Account theſe. That of the

inmoſt is one day, 18 hours, 28 minutes, and 36 ſeconds. The Second

ſpends 3 days, 13 hours, 13 min., 52 ſeconds in going round him. The

Third 7 days, 3 hours, 59 min., 40 ſec. The Fourth 16 days, 18 hours, 5

min., 6 ſec. The Diſtance of the innermoſt from Jupiter himſelf is 2⅚

of his Diameters. That of the Second is 4 and a half: Of the Third 7

and one ſixth part: Of the Fourth 12 and two thirds, of the ſame [And

Saturn’s.] Diameters. The Innermoſt of Saturn’s Satellites moves round

him in 1 day, 21 hours, 18 min., 31 ſec. The Second in 2 days, 17

hours, 41 min., 27 ſec. The Third in 4 days, 13 hours, 47 min., 16 ſec.

The Fourth in 15 days, 22 hours, 41 min., 11 ſec. The Fifth in 79 days,

7 hours, 53 min., 57 ſec. Their Diſtances from the Center of Saturn

are, that of the firſt almoſt one, that is 39 fortieth parts of the

Diameter of his Ring; that of the ſecond one and a quarter of thoſe

Diameters; of the third one and three quarters of them; of the fourth

four, or according to my Calculation, but 3 and a half; of the 5th 12,

which were found with vaſt Pains and Labour.
