CHAPTER XII

LIFE, UNIVERSAL AND ETERNAL

And now, while thanking my readers for having followed me so far in this

descriptive account of the marvels of the Cosmos, I must inquire what

philosophical impression has been produced on their minds by these

celestial excursions to the other worlds? Are you left indifferent to

the pageant of the Heavens? When your imagination was borne away to

these distant stars, suns of the infinite, these innumerable stellar

systems disseminated through a boundless eternity, did you ask what

existed there, what purpose was served by those dazzling spheres, what

effects resulted from these forces, radiations, energies? Did you

reflect that the elements which upon our little Earth determined a vital

activity so prodigious and so varied must needs have spread the waves of

an incomparably vaster and more diversified existence throughout the

immensities of the Universe? Have you felt that all can not be dead and

deserted, as we are tempted by the illusions of our terrestrial senses

and of our isolation to believe in the silence of the night: that on the

contrary, the real aim of Astronomy, instead of ending with statements

of the positions and movements of the stars, is to enable us to

penetrate to them, to make us divine, and know, and appreciate their

physical constitution, their degree of life and intellectuality in the

universal order?

On the Earth, it is Life and Thought that flourish; and it is Life and

Thought that we seek again in these starry constellations strewn to

Infinitude amid the immeasurable fields of Heaven.

The humble little planet that we inhabit presents itself to us as a

brimming cup, overflowing at every outlet. Life is everywhere. From the

bottom of the seas, from the valleys to the mountains, from the

vegetation that carpets the soil, from the mold in the fields and woods,

from the air we breathe, arises an immense, prodigious, and perpetual

murmur. Listen! it is the great voice of Nature, the sum of all the

unknown and mysterious voices that are forever calling to us, from the

ocean waves, from the forest winds, from the 300,000 kinds of insects

that are redundant everywhere, and make a lively community on the

surface of our globe. A drop of water contains thousands of curious and

agile creatures. A grain of dust from the streets of Paris is the home

of 130,000 bacteria. If we turn over the soil of a garden, field, or

meadow, we find the earthworms working to produce assimilable slime. If

we lift a stone in the path, we discover a crawling population. If we

gather a flower, detach a leaf, we everywhere find little insects living

a parasitic existence. Swarms of midges fly in the sun, the trees of the

wood are peopled with nests, the birds sing, and chase each other at

play, the lizards dart away at our approach, we trample down the

antheaps and the molehills. Life enwraps us in an inexorable

encroachment of which we are at once the heroes and the victims,

perpetuating itself to its own detriment, as imposed upon it by an

eternal reproduction. And this from all time, for the very stones of

which we build our houses are full of fossils so prodigiously multiplied

that one gram of such stone will often contain millions of shells,

marvels of geometrical perfection. The infinitely little is equal to the

infinitely great.

Life appears to us as a fatal law, an imperious force which all obey, as

the result and the aim of the association of atoms. This is illustrated

for us upon the Earth, our only field of direct observation. We must be

blind not to see this spectacle, deaf not to hear its reaching. On what

pretext could one suppose that our little globe which, as we have seen,

has received no privileges from Nature, is the exception; and that the

entire Universe, save for one insignificant isle, is devoted to vacancy,

solitude, and death?

We have a tendency to imagine that Life can not exist under conditions

other than terrestrial, and that the other worlds can only be inhabited

on the condition of being similar to our own. But terrestrial nature

itself demonstrates to us the error of this way of thinking. We die in

the water: fishes die out of the water. Again, short-sighted naturalists

affirm categorically that Life is impossible at the bottom of the sea:

1, because it is in complete darkness; 2, because the terrible pressure

would burst any organism; 3, because all motion would be impossible

there, and so on. Some inquisitive person sends down a dredge, and

brings up lovely creatures, so delicate in structure that the daintiest

touch must proceed with circumspection. There is no light in these

depths: they make it with their own phosphorescence. Other inquirers

visit subterranean caverns, and discover animals and plants whose organs

have been transformed by adaptation to their gloomy environment.

What right have we to say to the vital energy that radiates round every

Sun of the Universe: "Thus far shalt thou come, and no further"? In the

name of Science? An absolute mistake. The Known is an infinitesimal

island in the midst of the vast ocean of the Unknown. The deep seas

which seemed to be a barrier are, as we have seen, peopled with special

life. Some one objects: But after all, there is air there, there is

oxygen: oxygen is indispensable: a world without oxygen would be a

world of death, an eternally sterile desert. Why? Because we have not

yet come across beings that can breathe without air, and live without

oxygen? Another mistake. Even if we did not know of any, it would not

prove that they do not exist. But as it happens, we do know of such: the

_anaerobia_. These beings live without air, without oxygen. Better still:

oxygen kills them!

All the evidence goes to show that in interpreting as we ought the

spectacle of terrestrial life, and the positive facts acquired by

Science, we should enlarge the circle of our conceptions and our

judgments, and not limit extra-terrestrial existence to the servile

image of what is in existence here below. Terrestrial organic forms are

due to local causes upon our planet. The chemical constitution of water

and of the atmosphere, temperature, light, density, weight, are so many

elements that have gone to form our bodies. Our flesh is composed of

carbon, nitrogen, hydrogen, and oxygen combined in the state of water,

and of some other elements, among which we may instance sodium chloride

(salt). The flesh of animals is not chemically different from our own.

All this comes from the water and the air, and returns to them again.

The same elements, in very minute quantities, make up all living bodies.

The ox that browses on the grass is formed of the same flesh as the man

who eats the beef. All organized terrestrial matter is only carbon

combined in variable proportions with hydrogen, nitrogen, oxygen, etc.

But we have no right to forbid Nature to act differently in worlds from

which carbon is absent. A world, for example, in which silica replaces

carbon, silicic acid carbonic acid, might be inhabited by organisms

absolutely different from those which exist on the Earth, different not

only in form, but also in substance. We already know stars and suns for

which spectral analysis reveals a predominance of silica, _e.g._, Rigel

and Deneb. In a world where chlorine predominated, we might expect to

find hydrochloric acid, and all the fecund family of chlorides, playing

an important part in the phenomena of life. Might not bromine be

associated in other formations? Why, indeed, should we draw the line at

terrestrial chemistry? What is to prove that these elements are really

simple? May not hydrogen, carbon, oxygen, nitrogen, and sulphur all be

compounds? Their equivalents are multiples of the first: 1, 6, 8, 14,

16. And is even hydrogen the most simple of the elements? Is not its

molecule composed of atoms, and may there not exist a single species of

primitive atom, whose geometric arrangement and various associations

might constitute the molecules of the so-called simple elements?

In our own solar system we discover the essential differences between

certain planets. In the spectrum of Jupiter, for instance, we are aware

of the action of an unknown substance that manifests itself by a marked

absorption of certain red rays. This gas, which does not exist upon the

Earth, is seen still more obviously in the atmospheres of Saturn and

Uranus. Indeed, upon this last planet the atmosphere appears, apart from

its water vapor, to have no sort of analogy with our own. And in the

solar spectrum itself, many of the lines have not yet been identified

with terrestrial substances.

The interrelation of the planets is of course incontrovertible, since

they are all children of the same parent. But they differ among

themselves, not merely in respect of situation, position, volume, mass,

density, temperature, atmosphere, but again in physical and chemical

constitution. And the point we would now accent is that this diversity

should not be regarded as an obstacle to the manifestations of life,

but, on the contrary, as a new field open to the infinite fecundity of

the universal mother.

When our thoughts take wing, not only to our neighbors, Moon, Venus,

Mars, Jupiter, or Saturn, but still more toward the myriads of unknown

worlds that gravitate round the suns disseminated in space, we have no

plausible reason for imagining that the inhabitants of these other

worlds of Heaven resemble us in any way, whether in form, or even in

organic substance.

The substance of the terrestrial human body is due to the elements of

our planet, and notably to carbon. The terrestrial human form derives

from the ancestral animal forms to which it has gradually raised itself

by the continuous progress of the transformation of species. To us it

seems obvious that we are man or woman, because we have a head, a heart,

lungs, two legs, two arms, and so on. Nothing is less a matter of

course. That we are constituted as we are, is simply the result of our

pro-simian ancestors having also had a head, a heart, lungs, legs, and

arms--less elegant than your own, it is true, Madam, but still of the

same anatomy. And more and more, by the progress of paleontology, we are

delving down to the origin of beings. As certain as it is that the bird

derives from the reptile by a process of organic evolution, so certain

is it that terrestrial Humanity represents the topmost branches of the

huge genealogical tree, whereof all the limbs are brothers, and the

roots of which are plunged into the very rudiments of the most

elementary and primitive organisms.

The multitude of worlds is surely peopled by every imaginable and

unimaginable form. Terrestrial man is endowed with five senses, or

perhaps it is better to say six. Why should Nature stop at this point?

Why, for instance, may she not have given to certain beings an

electrical sense, a magnetic sense, a sense of orientation, an organ

able to perceive the ethereal vibrations of the infra-red or

ultra-violet, or permitted them to hear at a distance, or to see through

walls? We eat and digest like coarse animals, we are slaves to our

digestive tube: may there not be worlds in which a nutritive atmosphere

enables its fortunate inhabitants to dispense with this absurd process?

The least sparrow, even the dusky bat, has an advantage over us in that

it can fly through the air. Think how inferior are our conditions, since

the man of greatest genius, the most exquisite woman, are nailed to the

soil like any vulgar caterpillar before its metamorphosis! Would it be a

disadvantage to inhabit a world in which we might fly whither we would;

a world of scented luxury, full of animated flowers; a world where the

winds would be incapable of exciting a tempest, where several suns of

different colors--the diamond glowing with the ruby, or the emerald with

the sapphire--would burn night and day (azure nights and scarlet days)

in the glory of an eternal spring; with multi-colored moons sleeping in

the mirror of the waters, phosphorescent mountains, aerial

inhabitants,--men, women, or perhaps of other sexes,--perfect in their

forms, gifted with multiple sensibilities, luminous at will,

incombustible as asbestos, perhaps immortal, unless they commit suicide

out of curiosity? Lilliputian atoms as we are, let us once for all be

convinced that our imagination is but sterility, in the midst of an

infinitude hardly glimpsed by the telescope.

One important point seems always to be ignored expressly by those who

blindly deny the doctrine of the plurality of worlds. It is that this

doctrine does not apply more particularly to the present epoch than to

any other. _Our_ time is of no importance, no absolute value. Eternity

is the field of the Eternal Sower. There is no reason why the other

worlds should be inhabited _now_ more than at any other epoch.

What, indeed, is the Present Moment? It is an open trap through which

the Future falls incessantly into the gulf of the Past.

The immensity of Heaven bears in its bosom cradles as well as tombs,

worlds to come and perished worlds. It abounds in extinct suns, and

cemeteries. In all probability Jupiter is not yet inhabited. What does

this prove? The Earth was not inhabited during its primordial period:

what did that prove to the inhabitants of Mars or of the Moon, who were

perhaps observing it at that epoch, a few million years ago?

To pretend that our globe must be the only inhabited world because the

others do not resemble it, is to reason, not like a philosopher, but, as

we remarked before, like a fish. Every rational fish ought to assume

that it is impossible to live out of water, since its outlook and its

philosophy do not extend beyond its daily life. There is no answer to

this order of reasoning, except to advise a little wider perception, and

extension of the too narrow horizon of habitual ideas.

For us the resources of Nature may be considered infinite, and

"positive" science, founded upon our senses only, is altogether

inadequate, although it is the only possible basis of our reasoning. We

must learn to see with the eyes of our spirit.

As to the planetary systems other than our own, we are no longer reduced

to hypotheses. We already know with certainty that our Sun is no

exception, as was suggested, and is still maintained, by some theorists.

The discovery in itself is curious enough.

It is surely an exceptional situation that, given a sidereal system

composed of a central sun, and of one or more stars gravitating round

him, the plane of such a system should fall just within our line of

vision, and that it should revolve in such a way that the globes of

which it is composed pass exactly between this sun and ourselves in

turning round him, eclipsing him more or less during this transit. As,

on the other hand, the eclipses would be our only means of determining

the existence of these unknown planets (save indeed from perturbation,

as in the case of Sirius and Procyon), it might have seemed quixotic to

hope for like conditions in order to discover solar systems other than

our own. But these exceptional circumstances have reproduced themselves

at different parts of the Heavens.

Thus, for instance, we have seen that the variable star Algol owes its

variations in brilliancy, which reduce it from second to fourth

magnitude every sixty-nine hours, to the interposition of a body between

itself and the Earth, and celestial mechanics has already been able to

determine accurately the orbit of this body, its dimensions and its

mass, and even the flattening of the sun Algol. Here, then, is a system

in which we know the sun and an enormous planet, whose revolution is

effected in sixty-nine hours with extreme rapidity, as measured by the

spectroscope.

The star [delta] of Cepheus is in the same case: it is an orb eclipsed

in a period of 129 hours, and its eclipsing planet also revolves in the

plane of our vision. The variable star in Ophiuchus has an analogous

system, and observation has already revealed a great number of others.

Since, then, a certain number of solar systems differing from our own

have been revealed, as it were in section, to terrestrial observation,

this affords us sufficient evidence of the existence of an innumerable

quantity of solar systems scattered through the immensities of space,

and we are no longer reduced to conjecture.

On the other hand, analysis of the motions of several stars, such as

Sirius, Procyon, Altair, proves that these distant orbs have

companions,--planets not yet discovered by the telescope, and that

perhaps never will be discovered, because they are obscure, and lost in

the radiation of the star.

* * * * *

Some _savants_ have asserted that Life can not germinate if the

conditions of the environment differ too much from terrestrial

conditions.

This hypothesis is purely gratuitous, and we will now discuss it.

In order to examine what is happening on the Earth, let us mount the

ladder of time for a moment, to follow the evolutions of Nature.

There was an epoch when the Earth did not exist. Our planet, the future

world of our habitation, slept in the bosom of the solar nebula.

At last it came to birth, this cherished Earth, a gaseous, luminous

ball, poor reflection of the King of Orbs, its parent. Millions of years

rolled by before the condensation and cooling of this new globe were

sufficiently transformed to permit life to manifest itself in its most

rudimentary aspects.

The first organic forms of the protoplasm, the first aggregations of

cells, the protozoons, the zoophytes or plant-animals, the gelatinous

mussels of the still warm seas, were succeeded by the fishes, then by

the reptiles, the birds, the mammals, and lastly man, who at present

occupies the top of the genealogical tree, and crowns the animal

kingdom.

Humanity is comparatively young upon the Earth. We may attribute some

thousands of centuries of existence to it ... and some five years of

reason!

The terrestrial organisms, from the lowest up to man, are the resultant

of the forces in action at the surface of our planet. The earliest seem

to have been produced by the combinations of carbon with hydrogen and

nitrogen; they were, so to speak, without animation, save for some very

rudimentary sensibility; the sponges, corals, polyps, and medusae, give

us a notion of these primitive beings. They were formed in the tepid

waters of the primary epoch. As long as there were no continents, no

islands emerging from the level of the universal ocean, there were no

beings breathing in the air. The first aquatic creatures were succeeded

by the amphibia, the reptiles. Later on were developed the mammals and

the birds.

What, again, do we not owe to the plant-world of the primary epoch, of

the secondary epoch, of the tertiary epoch, which slowly prepared the

good nutritious soil of to-day, in which the roses flourish, and the

peach and strawberry ripen?

Before it gave birth to a Helen or a Cleopatra, life manifested itself

under the roughest forms, and in the most varied conditions. A

long-period comet passing in sight of the Earth from time to time would

have seen modifications of existence in each of its transits, in

accordance with a slow evolution, corresponding to the variation of the

conditions of existence, and progressing incessantly, for if Life is the

goal of nature, Progress is the supreme law.

The history of our planet is the history of life, with all its

metamorphoses. It is the same for all the worlds, with some exceptions

of orbs arrested in their development.

The constitution of living beings is in absolute relation with the

substances of which they are composed, the environment in which they

move, temperature, light, weight, density, the length of day and night,

the seasons, etc.--in a word, with all the cosmographic elements of a

world.

If, for example, we compare between themselves two worlds such as the

Earth and Neptune, utterly different from the point of view of distance

from the Sun, we could not for an instant suppose that organic

structures could have followed a parallel development on these planets.

The average temperature must be much lower on Neptune than on the Earth,

and the same holds for intensity of light. The years and seasons there

are 165 times longer than with us, the density of matter is three times

as weak, and weight is, on the contrary, a little greater. Under

conditions so different from our own, the activities of Nature would

have to translate themselves under other forms. And doubtless the

elementary bodies would not be found there in the same proportions.

Consequently we have to conclude that organs and senses would not be the

same there as here. The optic nerve, for instance, which has formed and

developed here from the rudimentary organ of the trilobite to the

marvels of the human eye, must be incomparably more sensitive upon

Neptune than in our dazzling solar luminosity, in order to perceive

radiations that we do not perceive here. In all probability, it is

replaced there by some other organ. The lungs, functioning there in

another atmosphere, are different from our own. So, too, for the stomach

and digestive organs. Corporeal forms, animal and human, can not

resemble those which exist upon the Earth.

Certain _savants_ contend that if the conditions differed too much from

terrestrial conditions, life could not be produced there at all. Yet we

have no right to limit the powers of Nature to the narrow bounds of our

sphere of observation, and to pretend that our planet and our Humanity

are the type of all the worlds. That is a hypothesis as ridiculous as it

is childish.

Do not let us be "personal," like children, and old people who never see

beyond their room. Let us learn to live in the Infinite and the Eternal.

From this larger point of view, the doctrine of the plurality of worlds

is the complement and the natural crown of Astronomy. What interests us

most in the study of the Universe is surely to know what goes on there.

* * * * *

These considerations show that, in all the ages, what really constitutes

a planet is not its skeleton but the life that vibrates upon its

surface.

And again, if we analyze things, we see that for the Procession of

Nature, life is all, and matter nothing.

What has become of our ancestors, the millions of human beings who

preceded us upon this globe? Where are their bodies? What is left of

them? Search everywhere. Nothing is left but the molecules of air,

water, dust, atoms of hydrogen, nitrogen, oxygen, carbon, etc., which

are incorporated in turn in the organism of every living being.

The whole Earth is a vast cemetery, and its finest cities are rooted in

the catacombs. But now, in crossing Paris, I passed for at least the

thousandth time near the Church of St. Germain-l'Auxerrois, and was

obliged to turn out of the direct way, on account of excavations. I

looked down, and saw that immediately below the pavement, they had just

uncovered some stone coffins still containing the skeletons that had

reposed there for ten centuries. From time immemorial the passers-by had

trampled them unwittingly under foot. And I reflected that it is much

the same in every quarter of Paris. Only yesterday, some Roman tombs and

a coin with the effigy of Nero were found in a garden near the

Observatory.

And from the most general standpoint of Life, the whole world is in the

same case, and even more so, seeing that all that exists, all that

lives, is formed of elements that have already been incorporated in

other beings, no longer living. The roses that adorn the bosom of the

fair ... but I will not enlarge upon this topic.

And you, so strong and virile, of what elements is your splendid body

formed? Where have the elements you absorb to-day in respiration and

assimilation been drawn from, what lugubrious adventures have they been

subject to? Think away from it: do not insist on this point: on no

account consider it....

And yet, let us dwell on it, since this reality is the most evident

demonstration of the ideal; since what exists is you, is all of us, is

_Life_; and matter is only its substance, like the materials of a house,

and even less so, since its particles only pass rapidly through the

framework of our bodies. A heap of stones does not make a house.

Quintillions of tons of materials would not represent the Earth or any

other world.

Yes, what really exists, what constitutes a complete orb, is the city of

Life. Let us recognize that the flower of life flourishes on the surface

of our planet, embellishing it with its perfume; that it is just this

life that we see and admire,--of which we form part,--and which is the

_raison d'etre_ of things; that matter floats, and crosses, and crosses

back again, in the web of living beings,--and the reality, the goal, is

not matter--it is the life matter is employed upon.

Yes, matter passes, and being also, after sharing in the concerted

symphony of life.

And indeed everything passes rapidly!

What irrepressible grief, what deep melancholy, what ineffaceable

regrets we feel, when as age comes on we look back, when we see our

friends fallen upon the road one after the other, above all when we

visit the beloved scenes of our childhood, those homes of other years,

that witnessed our first start in terrestrial existence, our first

games, our first affections--those affections of childhood that seemed

eternal--when we wander over those fields and valleys and hills, when

we see again the landscape whose aspect has hardly changed, and whose

image is so intimately linked with our first impressions. There near

this fireside the grandfather danced us on his knee, and told us

blood-curdling stories; here the kind grandmother came to see if we were

comfortably tucked in, and not likely to fall out of the big bed; in

this little wood, along these alleys that seemed endless, we spread our

nets for birds; in this stream we fished for crayfish; there on the path

we played at soldiers with our elders, who were always captains; on

these slopes we found rare stones and fossils, and mysterious

petrifactions; on this hill we admired the fine sunsets, the appearance

of the stars, the form of the constellations. There we began to live, to

think, to love, to form attachments, to dream, to question every

problem, to breathe intellectually and physically. And now, where is

this beloved grandfather? the good grandmother? where are all whom we

knew in infancy? where are our dreams of childhood? Winged thoughts

still seem to flutter in the air, and that is all. People, caresses,

voices, all have gone and vanished. The cemetery has closed over them

all. There is a silent void. Were all those fine and sunny hours an

illusion? Was it only to weep one day over this negation that our

childish hearts were so tenderly attached to these fleeting shadows? Is

there nothing, down the long length of human history, but eternal

delusion?

It is here, above all, that we find ourselves in presence of the

greatest problems. Life is the goal, it is Life that produces the

conditions of Thought. Without Thought, where would be the Universe?

We feel that without life and thought, the Universe would be an empty

theater, and Astronomy itself, sublime science, a vain research. We feel

that this is the truth, veiled as yet to actual science, and that human

races kindred with our own exist there in the immensities of space. Yes,

we _feel_ that this is truth.

But we would fain go a little further in our knowledge of the universe,

and penetrate in some measure the secret of our destinies. We would know

if these distant and unknown Humanities are not attached to us by

mysterious cords, if our life, which will assuredly be extinguished at

some definite moment here below, will not be prolonged into the regions

of Eternity.

A moment ago we said that nothing is left of the body. Millions of

organisms have lived, there are no remains of them. Air, water, smoke,

dust. _Memento, homo, quia pulvis es et in pulverem revertebis._

Remember oh man! that dust thou art, and unto dust thou shalt return,

says the priest to the faithful, when he scatters the ashes on the day

after the carnival.

The body disappears entirely. It goes where the corpse of Caesar went an

hour after the extinction of his pyre. Nor will there be more remains of

any of us. And the whole of Humanity, and the Earth itself, will also

disappear one day. Let no one talk of the Progress of Humanity as an

end! That would be too gross a decoy.

If the soul were also to disappear in smoke, what would be left of the

vital and intellectual organization of the world? Nothing.

On this hypothesis, _all_ would be reduced to _nothing_.

Our reason is not immense, our terrestrial faculties are sufficiently

limited, but this reason and these faculties suffice none the less to

make us feel the improbability, the absurdity, of this hypothesis, and

we reject it as incompatible with the sublime grandeur of the spectacle

of the universe.

Undoubtedly, Creation does not seem to concern itself with us. It

proceeds on its inexorable course without consulting our sensations.

With the poet we regret the implacable serenity of Nature, opposing the

irony of its smiling splendor to our mourning, our revolts, and our

despair.

Que peu de temps suffit pour changer toutes choses!

Nature au front serein, comme vous oubliez!

Et comme vous brisez dans vos metamorphoses

Les fils mysterieux ou nos coeurs sont lies.

D'autres vont maintenant passer ou nous passames;

Nous y sommes venus, d'autres vont y venir,

Et le songe qu'avaient ebauche nos deux ames,

Ils le continueront sans pouvoir le finir.

Car personne ici-bas ne termine et n'acheve;

Les pires des humains sont comme les meilleurs;

Nous nous eveillons tous au meme endroit du reve:

Tout commence en ce monde et tout finit ailleurs.

Repondez, vallon pur, repondez, solitude!

O Nature, abritee en ce desert si beau,

Quand nous serons couches tous deux, dans l'attitude

Que donne aux morts pensifs la forme du tombeau,

Est-ce que vous serez a ce point insensible,

De nous savoir perdus, morts avec nos amours,

Et de continuer votre fete paisible

Et de toujours sourire et de chanter toujours?[16]

_Note.--Free Translation._

How brief a time suffices for all things to change! Serene-fronted

Nature, too soon you will forget!... in your metamorphoses

ruthlessly snapping the cords that bind our hearts together!

Others will pass where we pass; we have arrived, and others will

arrive after us: the thought sketched out by our souls will be

pursued by theirs ... and they will not find the solution of it.

For no one here begins or finishes: the worst are as the best of

humans; we all awake at the same moment of the dream: we all begin

in this world, and end otherwhere.

Reply, sweet valley, reply, solitude; O Nature, sheltering in this

splendid desert, when we are both asleep, and cast by the tomb into

the attitude of pensive death.

Will you to the last verge be so insensible, that, knowing us lost,

and dead with our loves, you will pursue your cheerful feast, and

smile, and sing always?

Yes, mortals may say that when they are sleeping in the grave, spring

and summer will still smile and sing; husband and wife may ask

themselves if they will meet again some day, in another sphere; but do

we not _feel_ that our destinies can not be terminated here, and that

short of absolute and final nonentity for everything, they must be

renewed beyond, in that starry Heaven to which every dream has flown

instinctively since the first origins of Humanity?

As our planet is only a province of the Infinite Heavens, so our actual

existence is only a stage in Eternal Life. Astronomy, by giving us

wings, conducts us to the sanctuary of truth. The specter of death has

departed from our Heaven. The beams of every star shed a ray of hope

into our hearts. On each sphere Nature chants the paean of Life Eternal.

FOOTNOTES:

[1] The French edition of this book is entitled Astronomy for

Women.--TRANSLATOR.

[2] 1 kilometer = 0.6214 mile; 100 kilometers may be taken as 62 miles.

1 kilogram is about 2.2 lb.; 5 kilograms = 11 lb.--TRANSLATOR.

[3] It is useful to know the letters of the Greek Alphabet. They are

easily learned, as follows:

[alpha] Alpha

[beta] Beta

[gamma] Gamma

[delta] Delta

[epsilon] Epsilon

[zeta] Zeta

[eta] Eta

[theta] Theta

[iota] Iota

[kappa] Kappa

[lambda] Lambda

[mu] Mu

[nu] Nu

[xi] Xi

[omicron] Omicron

[pi] Pi

[rho] Rho

[sigma] or [sigma] Sigma

[tau] Tau

[upsilon] Upsilon

[phi] Phi

[chi] Chi

[psi] Psi

[omega] Omega

[4] All the stars visible at any hour during the year can easily be

found with the help of the author's Planisphere mobile.

[5] Let it be remarked in passing that the stars might be much farther

off than they are, and invisible to our eyes; the Heavens would then

assume the aspect of an absolutely empty space, the moon and planets

alone remaining.

[6] 14" = 14 seconds of arc. One second of the circle is an exceedingly

minute quantity. It is 1 millimeter seen at a distance of 206 meters.

One millimeter seen at a distance of 20 m. 62 = 10 secs. These values

are invisible to the unaided eye.

[7] These fine double stars can be observed with the help of the

smallest telescope.

[8] For the explanation of the angular distances of degrees, minutes,

and seconds, see Chapter XI, on Methods of Measurement.

[9] The author has endeavored on the plates to represent the aspect of

the Earth in the starry sky of Mercury, Venus, and Mars; but in all

representations of this kind the stars are necessarily made too large.

By calculation the diameters of the Earth and Moon as seen from the

planets, and their distances, are as follows:

Diameter of Diameter of Distance

the Earth. the Moon. Earth-Moon.

Of Mercury (opposition) 20" 8" 871"

Of Venus (opposition) 64" 17" 1,928"

Of Mars (quadrature) 15" 4" 464"

Of Jupiter (quadrature) 3.5" 0.1" 105"

These aspects will be appreciated if we remember that the distance of

the components of [epsilon] Lyre = 207", that of Atlas in Pleione =

301", and that of the stars Mizar and Alcor = 708".

[10] A few evenings ago, after observing Venus in the calm and silent

Heavens at the close of day, my eyes fell upon a drawing sent me by my

friend Gustave Dore, which is included in the illustrations of his

wonderful edition of Dante's Divina Commedia. This drawing seems to be

in place here, and I offer my readers a poor reproduction of it, taken

from the fine engraving in the book. Dante and Virgil, in the peaceful

evening, are contemplating _lo bel pianeta ch'ad amar conforta_ (the

beautiful planet that incites to love).

[11] Strictly speaking, 1 kilometer = 0.6214 mile. Here, as throughout,

the equivalents are only given in round numbers.--TRANSLATOR.

[12] Translator: Compare the well-known English rhyme:

Thirty days hath September,

April, June, and November.

While all the rest have thirty-one,

Excepting February alone,

In which but twenty-eight appear

And twenty-nine when comes Leap Year.

[13] Fifty-eight different pictures of the aspect of the Moon to the

unaided eye will be found in the Monthly Bulletins of the Astronomical

Society of France, for the year 1900, in pursuance of an investigation

made by the author among the different members of the Society.

[14] My readers are charged not to speak of this property (which is

fairly extensive), lest the Budget Commission, at the end of its

resources, should be tempted to put on an unexpected tax. This ring,

which the astronomers presented to me in the year 1887, is almost in the

center of the lunar disk, to the north of Ptolemy and Herschel.
