every case formally wedded to the button…holes。 Some day or other;

after a long time spent in measuring space; or in accumulating Xs

under Aa…Gg; they succeed in analyzing some natural law; and resolve

it into its elemental principles; and all on a sudden the crowd gapes

at a new machine; or it is a handcart perhaps that overwhelms us with

astonishment by the apt simplicity of its construction。 The modest man

of science smiles at his admirers; and remarks; 〃What is that

invention of mine? Nothing whatever。 Man cannot create a force; he can

but direct it; and science consists in learning from nature。〃



The mechanician was standing bolt upright; planted on both feet; like

some victim dropped straight from the gibbet; when Raphael broke in

upon him。 He was intently watching an agate ball that rolled over a

sun…dial; and awaited its final settlement。 The worthy man had

received neither pension nor decoration; he had not known how to make

the right use of his ability for calculation。 He was happy in his life

spent on the watch for a discovery; he had no thought either of

reputation; of the outer world; nor even of himself; and led the life

of science for the sake of science。



〃It is inexplicable;〃 he exclaimed。 〃Ah; your servant; sir;〃 he went

on; becoming aware of Raphael's existence。 〃How is your mother? You

must go and see my wife。〃



〃And I also could have lived thus;〃 thought Raphael; as he recalled

the learned man from his meditations by asking of him how to produce

any effect on the talisman; which he placed before him。



〃Although my credulity must amuse you; sir;〃 so the Marquis ended; 〃I

will conceal nothing from you。 That skin seems to me to be endowed

with an insuperable power of resistance。〃



〃People of fashion; sir; always treat science rather superciliously;〃

said Planchette。 〃They all talk to us pretty much as the incroyable

did when he brought some ladies to see Lalande just after an eclipse;

and remarked; 'Be so good as to begin it over again!' What effect do

you want to produce? The object of the science of mechanics is either

the application or the neutralization of the laws of motion。 As for

motion pure and simple; I tell you humbly; that we cannot possibly

define it。 That disposed of; unvarying phenomena have been observed

which accompany the actions of solids and fluids。 If we set up the

conditions by which these phenomena are brought to pass; we can

transport bodies or communicate locomotive power to them at a

predetermined rate of speed。 We can project them; divide them up in a

few or an infinite number of pieces; accordingly as we break them or

grind them to powder; we can twist bodies or make them rotate; modify;

compress; expand; or extend them。 The whole science; sir; rests upon a

single fact。



〃You see this ball;〃 he went on; 〃here it lies upon this slab。 Now; it

is over there。 What name shall we give to what has taken place; so

natural from a physical point of view; so amazing from a moral?

Movement; locomotion; changing of place? What prodigious vanity lurks

underneath the words。 Does a name solve the difficulty? Yet it is the

whole of our science for all that。 Our machines either make direct use

of this agency; this fact; or they convert it。 This trifling

phenomenon; applied to large masses; would send Paris flying。 We can

increase speed by an expenditure of force; and augment the force by an

increase of speed。 But what are speed and force? Our science is as

powerless to tell us that as to create motion。 Any movement whatever

is an immense power; and man does not create power of any kind。

Everything is movement; thought itself is a movement; upon movement

nature is based。 Death is a movement whose limitations are little

known。 If God is eternal; be sure that He moves perpetually; perhaps

God is movement。 That is why movement; like God is inexplicable;

unfathomable; unlimited; incomprehensible; intangible。 Who has ever

touched; comprehended; or measured movement? We feel its effects

without seeing it; we can even deny them as we can deny the existence

of a God。 Where is it? Where is it not? Whence comes it? What is its

source? What is its end? It surrounds us; it intrudes upon us; and yet

escapes us。 It is evident as a fact; obscure as an abstraction; it is

at once effect and cause。 It requires space; even as we; and what is

space? Movement alone recalls it to us; without movement; space is but

an empty meaningless word。 Like space; like creation; like the

infinite; movement is an insoluble problem which confounds human

reason; man will never conceive it; whatever else he may be permitted

to conceive。



〃Between each point in space occupied in succession by that ball;〃

continued the man of science; 〃there is an abyss confronting human

reason; an abyss into which Pascal fell。 In order to produce any

effect upon an unknown substance; we ought first of all to study that

substance; to know whether; in accordance with its nature; it will be

broken by the force of a blow; or whether it will withstand it; if it

breaks in pieces; and you have no wish to split it up; we shall not

achieve the end proposed。 If you want to compress it; a uniform

impulse must be communicated to all the particles of the substance; so

as to diminish the interval that separates them in an equal degree。 If

you wish to expand it; we should try to bring a uniform eccentric

force to bear on every molecule; for unless we conform accurately to

this law; we shall have breaches in continuity。 The modes of motion;

sir; are infinite; and no limit exists to combinations of movement。

Upon what effect have you determined?〃



〃I want any kind of pressure that is strong enough to expand the skin

indefinitely;〃 began Raphael; quite of out patience。



〃Substance is finite;〃 the mathematician put in; 〃and therefore will

not admit of indefinite expansion; but pressure will necessarily

increase the extent of surface at the expense of the thickness; which

will be diminished until the point is reached when the material gives

out〃



〃Bring about that result; sir;〃 Raphael cried; 〃and you will have

earned millions。〃



〃Then I should rob you of your money;〃 replied the other; phlegmatic

as a Dutchman。 〃I am going to show you; in a word or two; that a

machine can be made that is fit to crush Providence itself in pieces

like a fly。 It would reduce a man to the conditions of a piece of

waste paper; a manboots and spurs; hat and cravat; trinkets and

gold; and all〃



〃What a fearful machine!〃



〃Instead of flinging their brats into the water; the Chinese ought to

make them useful in this way;〃 the man of science went on; without

reflecting on the regard man has for his progeny。



Quite absorbed by his idea; Planchette took an empty flower…pot; with

a hole in the bottom; and put it on the surface of the dial; then he

went to look for a little clay in a corner of the garden。 Raphael

stood spellbound; like a child to whom his nurse is telling some

wonderful story。 Planchette put the clay down upon the slab; drew a

pruning…knife from his pocket; cut two branches from an elder tree;

and began to clean them of pith by blowing through them; as if Raphael

had not been present。



〃There are the rudiments of the apparatus;〃 he said。 Then he connected

one of the wooden pipes with the bottom of the flower…pot by way of a

clay joint; in such a way that the mouth of the elder stem was just

under the hole of the flower…pot; you might have compared it to a big

tobacco…pipe。 He spread a bed of clay over the surface of the slab; in

a shovel…shaped mass; set down the flower…pot at the wider end of it;

and laid the pipe of the elder stem along the portion which

represented the handle of the shovel。 Next he put a lump of clay at

the end of the elder stem and therein planted the other pipe; in an

upright position; forming a second elbow which connected it with the

first horizontal pipe in such a manner that the air; or any given

fluid in circulation; could flow through this improvised piece of

mechanism from the mouth of the vertical tube; along the intermediate

passages; and so into the large empty flower…pot。



〃This apparatus; sir;〃 he said to Raphael; with all the gravity of an

academician pronouncing his initiatory discourse; 〃is one of the great

Pascal's grandest claims upon our admiration。〃



〃I don't understand。〃



The man of science smiled。 He went up to a fruit…tree and took down a

little phial in which the druggist had sent him some liquid for

catching ants; he broke off the bottom and made a funnel of the top;

carefully fitting it to the mouth of the vertical hollowed stem that

he had set in the clay; and at the opposite end to the great

reservoir; represented by the flower…pot。 Next; by means of a

watering…pot; he poured in sufficient water to rise to the same level

in the large vessel and in the tiny circular funnel at the end of the
