  given time。 Having arranged all this; the rest of the plan is
  obvious。 My bed was so contrived upon the floor of the car; as to
  bring my head; in lying down; immediately below the mouth of the
  pitcher。 It was evident; that; at the expiration of an hour; the
  pitcher; getting full; would be forced to run over; and to run over
  at the mouth; which was somewhat lower than the rim。 It was also
  evident; that the water thus falling from a height of more than four
  feet; could not do otherwise than fall upon my face; and that the
  sure consequences would be; to waken me up instantaneously; even from
  the soundest slumber in the world。
  〃It was fully eleven by the time I had completed these arrangements;
  and I immediately betook myself to bed; with full confidence in the
  efficiency of my invention。 Nor in this matter was I disappointed。
  Punctually every sixty minutes was I aroused by my trusty
  chronometer; when; having emptied the pitcher into the bung…hole of
  the keg; and performed the duties of the condenser; I retired again
  to bed。 These regular interruptions to my slumber caused me even less
  discomfort than I had anticipated; and when I finally arose for the
  day; it was seven o'clock; and the sun had attained many degrees
  above the line of my horizon。
  〃April 3d。 I found the balloon at an immense height indeed; and the
  earth's apparent convexity increased in a material degree。 Below me
  in the ocean lay a cluster of black specks; which undoubtedly were
  islands。 Far away to the northward I perceived a thin; white; and
  exceedingly brilliant line; or streak; on the edge of the horizon;
  and I had no hesitation in supposing it to be the southern disk of
  the ices of the Polar Sea。 My curiosity was greatly excited; for I
  had hopes of passing on much farther to the north; and might
  possibly; at some period; find myself placed directly above the Pole
  itself。 I now lamented that my great elevation would; in this case;
  prevent my taking as accurate a survey as I could wish。 Much;
  however; might be ascertained。 Nothing else of an extraordinary
  nature occurred during the day。 My apparatus all continued in good
  order; and the balloon still ascended without any perceptible
  vacillation。 The cold was intense; and obliged me to wrap up closely
  in an overcoat。 When darkness came over the earth; I betook myself to
  bed; although it was for many hours afterward broad daylight all
  around my immediate situation。 The water…clock was punctual in its
  duty; and I slept until next morning soundly; with the exception of
  the periodical interruption。
  〃April 4th。 Arose in good health and spirits; and was astonished at
  the singular change which had taken place in the appearance of the
  sea。 It had lost; in a great measure; the deep tint of blue it had
  hitherto worn; being now of a grayish…white; and of a lustre dazzling
  to the eye。 The islands were no longer visible; whether they had
  passed down the horizon to the southeast; or whether my increasing
  elevation had left them out of sight; it is impossible to say。 I was
  inclined; however; to the latter opinion。 The rim of ice to the
  northward was growing more and more apparent。 Cold by no means so
  intense。 Nothing of importance occurred; and I passed the day in
  reading; having taken care to supply myself with books。
  〃April 5th。 Beheld the singular phenomenon of the sun rising while
  nearly the whole visible surface of the earth continued to be
  involved in darkness。 In time; however; the light spread itself over
  all; and I again saw the line of ice to the northward。 It was now
  very distinct; and appeared of a much darker hue than the waters of
  the ocean。 I was evidently approaching it; and with great rapidity。
  Fancied I could again distinguish a strip of land to the eastward;
  and one also to the westward; but could not be certain。 Weather
  moderate。 Nothing of any consequence happened during the day。 Went
  early to bed。
  〃April 6th。 Was surprised at finding the rim of ice at a very
  moderate distance; and an immense field of the same material
  stretching away off to the horizon in the north。 It was evident that
  if the balloon held its present course; it would soon arrive above
  the Frozen Ocean; and I had now little doubt of ultimately seeing the
  Pole。 During the whole of the day I continued to near the ice。 Toward
  night the limits of my horizon very suddenly and materially
  increased; owing undoubtedly to the earth's form being that of an
  oblate spheroid; and my arriving above the flattened regions in the
  vicinity of the Arctic circle。 When darkness at length overtook me; I
  went to bed in great anxiety; fearing to pass over the object of so
  much curiosity when I should have no opportunity of observing it。
  〃April 7th。 Arose early; and; to my great joy; at length beheld what
  there could be no hesitation in supposing the northern Pole itself。
  It was there; beyond a doubt; and immediately beneath my feet; but;
  alas! I had now ascended to so vast a distance; that nothing could
  with accuracy be discerned。 Indeed; to judge from the progression of
  the numbers indicating my various altitudes; respectively; at
  different periods; between six A。M。 on the second of April; and
  twenty minutes before nine A。M。 of the same day (at which time the
  barometer ran down); it might be fairly inferred that the balloon had
  now; at four o'clock in the morning of April the seventh; reached a
  height of not less; certainly; than 7;254 miles above the surface of
  the sea。 This elevation may appear immense; but the estimate upon
  which it is calculated gave a result in all probability far inferior
  to the truth。 At all events I undoubtedly beheld the whole of the
  earth's major diameter; the entire northern hemisphere lay beneath me
  like a chart orthographically projected: and the great circle of the
  equator itself formed the boundary line of my horizon。 Your
  Excellencies may; however; readily imagine that the confined regions
  hitherto unexplored within the limits of the Arctic circle; although
  situated directly beneath me; and therefore seen without any
  appearance of being foreshortened; were still; in themselves;
  comparatively too diminutive; and at too great a distance from the
  point of sight; to admit of any very accurate examination。
  Nevertheless; what could be seen was of a nature singular and
  exciting。 Northwardly from that huge rim before mentioned; and which;
  with slight qualification; may be called the limit of human discovery
  in these regions; one unbroken; or nearly unbroken; sheet of ice
  continues to extend。 In the first few degrees of this its progress;
  its surface is very sensibly flattened; farther on depressed into a
  plane; and finally; becoming not a little concave; it terminates; at
  the Pole itself; in a circular centre; sharply defined; wbose
  apparent diameter subtended at the balloon an angle of about
  sixty…five seconds; and whose dusky hue; varying in intensity; was;
  at all times; darker than any other spot upon the visible hemisphere;
  and occasionally deepened into the most absolute and impenetrable
  blackness。 Farther than this; little could be ascertained。 By twelve
  o'clock the circular centre had materially decreased in
  circumference; and by seven P。M。 I lost sight of it entirely; the
  balloon passing over the western limb of the ice; and floating away
  rapidly in the direction of the equator。
  〃April 8th。 Found a sensible diminution in the earth's apparent
  diameter; besides a material alteration in its general color and
  appearance。 The whole visible area partook in different degrees of a
  tint of pale yellow; and in some portions had acquired a brilliancy
  even painful to the eye。 My view downward was also considerably
  impeded by the dense atmosphere in the vicinity of the surface being
  loaded with clouds; between whose masses I could only now and then
  obtain a glimpse of the earth itself。 This difficulty of direct
  vision had troubled me more or less for the last forty…eight hours;
  but my present enormous elevation brought closer together; as it
  were; the floating bodies of vapor; and the inconvenience became; of
  course; more and more palpable in proportion to my ascent。
  Nevertheless; I could easily perceive that the balloon now hovered
  above the range of great lakes in the continent of North America; and
  was holding a course; due south; which would bring me to the tropics。
  This circumstance did not fail to give me the most heartful
  satisfaction; and I hailed it as a happy omen of ultimate success。
  Indeed; the direction I had hitherto taken; had filled me with
  uneasiness; for it was evident that; had I continued it much longer;
  there would have been no possibility of my arriving at the moon at
  all; whose orbit is inclined to the ecliptic at only the small angle
  of 5 degrees 8' 48〃。
  〃April 9th。 To…day the earth's diameter was greatly diminished; and
  the color of the surface assumed hourly a deeper tint of yellow。 The
  balloon kept steadily on her course to the southward; and arrived; at
  nine P。M。; over the northern edge of the Mexican Gulf。
  〃April 10th。 I was suddenly aroused from
