  moon (applying this designation to our globe) but on one side of
  her disc。  Now if this were the case with the earth if; for
  example; Europe never saw the moon; and she was only visible at
  the antipodes; imagine to yourself the astonishment of a
  European on arriving in Australia。〃
  〃They would make the voyage for nothing but to see the moon!〃
  replied Michel。
  〃Very well!〃 continued Barbicane; 〃that astonishment is reserved
  for the Selenites who inhabit the face of the moon opposite to
  the earth; a face which is ever invisible to our countrymen of
  the terrestrial globe。〃
  〃And which we should have seen;〃 added Nicholl; 〃if we had arrived
  here when the moon was new; that is to say fifteen days later。〃
  〃I will add; to make amends;〃 continued Barbicane; 〃that the
  inhabitants of the visible face are singularly favored by nature;
  to the detriment of their brethren on the invisible face。
  The latter; as you see; have dark nights of 354 hours; without
  one single ray to break the darkness。  The other; on the contrary;
  when the sun which has given its light for fifteen days sinks
  below the horizon; see a splendid orb rise on the opposite horizon。
  It is the earth; which is thirteen times greater than the
  diminutive moon that we know the earth which developes itself
  at a diameter of two degrees; and which sheds a light thirteen
  times greater than that qualified by atmospheric strata the
  earth which only disappears at the moment when the sun reappears
  in its turn!〃
  〃Nicely worded!〃 said Michel; 〃slightly academical perhaps。〃
  〃It follows; then;〃 continued Barbicane; without knitting his
  brows; 〃that the visible face of the disc must be very agreeable
  to inhabit; since it always looks on either the sun when the
  moon is full; or on the earth when the moon is new。〃
  〃But;〃 said Nicholl; 〃that advantage must be well compensated by
  the insupportable heat which the light brings with it。〃
  〃The inconvenience; in that respect; is the same for the two
  faces; for the earth's light is evidently deprived of heat。
  But the invisible face is still more searched by the heat than
  the visible face。  I say that for _you_; Nicholl; because Michel
  will probably not understand。〃
  〃Thank you;〃 said Michel。
  〃Indeed;〃 continued Barbicane; 〃when the invisible face receives
  at the same time light and heat from the sun; it is because the
  moon is new; that is to say; she is situated between the sun and
  the earth。  It follows; then; considering the position which she
  occupies in opposition when full; that she is nearer to the sun
  by twice her distance from the earth; and that distance may be
  estimated at the two…hundredth part of that which separates the
  sun from the earth; or in round numbers 400;000 miles。  So that
  invisible face is so much nearer to the sun when she receives
  its rays。〃
  〃Quite right;〃 replied Nicholl。
  〃On the contrary;〃 continued Barbicane。
  〃One moment;〃 said Michel; interrupting his grave companion。
  〃What do you want?〃
  〃I ask to be allowed to continue the explanation。〃
  〃And why?〃
  〃To prove that I understand。〃
  〃Get along with you;〃 said Barbicane; smiling。
  〃On the contrary;〃 said Michel; imitating the tone and gestures
  of the president; 〃on the contrary; when the visible face of the
  moon is lit by the sun; it is because the moon is full; that is
  to say; opposite the sun with regard to the earth。  The distance
  separating it from the radiant orb is then increased in round
  numbers to 400;000 miles; and the heat which she receives must
  be a little less。〃
  〃Very well said!〃 exclaimed Barbicane。  〃Do you know; Michel;
  that; for an amateur; you are intelligent。〃
  〃Yes;〃 replied Michel coolly; 〃we are all so on the Boulevard
  des Italiens。〃
  Barbicane gravely grasped the hand of his amiable companion; and
  continued to enumerate the advantages reserved for the inhabitants
  of the visible face。
  Among others; he mentioned eclipses of the sun; which only take
  place on this side of the lunar disc; since; in order that they
  may take place; it is necessary for the moon to be _in
  opposition_。  These eclipses; caused by the interposition of the
  earth between the moon and the sun; can last _two hours_; during
  which time; by reason of the rays refracted by its atmosphere;
  the terrestrial globe can appear as nothing but a black point
  upon the sun。
  〃So;〃 said Nicholl; 〃there is a hemisphere; that invisible
  hemisphere which is very ill supplied; very ill treated;
  by nature。〃
  〃Never mind;〃 replied Michel; 〃if we ever become Selenites; we
  will inhabit the visible face。  I like the light。〃
  〃Unless; by any chance;〃 answered Nicholl; 〃the atmosphere should
  be condensed on the other side; as certain astronomers pretend。〃
  〃That would be a consideration;〃 said Michel。
  Breakfast over; the observers returned to their post。  They tried
  to see through the darkened scuttles by extinguishing all light
  in the projectile; but not a luminous spark made its way through
  the darkness。
  One inexplicable fact preoccupied Barbicane。  Why; having passed
  within such a short distance of the moonabout twenty…five
  miles only why the projectile had not fallen?  If its speed
  had been enormous; he could have understood that the fall would
  not have taken place; but; with a relatively moderate speed;
  that resistance to the moon's attraction could not be explained。
  Was the projectile under some foreign influence?  Did some kind
  of body retain it in the ether?  It was quite evident that it
  could never reach any point of the moon。  Whither was it going?
  Was it going farther from; or nearing; the disc?  Was it being
  borne in that profound darkness through the infinity of space?
  How could they learn; how calculate; in the midst of this night?
  All these questions made Barbicane uneasy; but he could not
  solve them。
  Certainly; the invisible orb was _there_; perhaps only some few
  miles off; but neither he nor his companions could see it。
  If there was any noise on its surface; they could not hear it。
  Air; that medium of sound; was wanting to transmit the groanings
  of that moon which the Arabic legends call 〃a man already half
  granite; and still breathing。〃
  One must allow that that was enough to aggravate the most
  patient observers。  It was just that unknown hemisphere which
  was stealing from their sight。  That face which fifteen days
  sooner; or fifteen days later; had been; or would be; splendidly
  illuminated by the solar rays; was then being lost in utter darkness。
  In fifteen days where would the projectile be?  Who could say?
  Where would the chances of conflicting attractions have drawn
  it to?  The disappointment of the travelers in the midst of this
  utter darkness may be imagined。  All observation of the lunar
  disc was impossible。  The constellations alone claimed all their
  attention; and we must allow that the astronomers Faye; Charconac;
  and Secchi; never found themselves in circumstances so favorable
  for their observation。
  Indeed; nothing could equal the splendor of this starry world;
  bathed in limpid ether。  Its diamonds set in the heavenly vault
  sparkled magnificently。  The eye took in the firmament from the
  Southern Cross to the North Star; those two constellations which
  in 12;000 years; by reason of the succession of equinoxes; will
  resign their part of the polar stars; the one to Canopus in the
  southern hemisphere; the other to Wega in the northern。
  Imagination loses itself in this sublime Infinity; amid which
  the projectile was gravitating; like a new star created by the
  hand of man。  From a natural cause; these constellations shone
  with a soft luster; they did not twinkle; for there was no
  atmosphere which; by the intervention of its layers unequally
  dense and of different degrees of humidity; produces
  this scintillation。  These stars were soft eyes; looking out
  into the dark night; amid the silence of absolute space。
  Long did the travelers stand mute; watching the constellated
  firmament; upon which the moon; like a vast screen; made an
  enormous black hole。  But at length a painful sensation drew
  them from their watchings。  This was an intense cold; which soon
  covered the inside of the glass of the scuttles with a thick
  coating of ice。  The sun was no longer warming the projectile
  with its direct rays; and thus it was losing the heat stored up
  in its walls by degrees。  This heat was rapidly evaporating into
  space by radiation; and a considerably lower temperature was
  the result。  The humidity of the interior was changed into ice
  upon contact with the glass; preventing all observation。
  Nicholl consulted the thermometer; and saw that it had fallen to
  seventeen degrees (Centigrade) below zero。 '3'  So that; in spite
  of the many reasons for economizing; Barbicane; after having
  begged light from the gas; was also obliged to beg for heat。
  The projectile's low temperature was no longer endurable。
  Its tenants would have been frozen to death。
  '3' 1@ Fahrenheit。
  〃Well!〃 observed Michel; 〃we cannot reasonably complain of the
  monotony of our journey!  What variety we have had; at least
  in temperature。  Now we are blinded with light and saturated with
  heat; like the Indians of the Pampas! now plunged into profou
