<p>[Astounding News by Express, <i>via</i> Norfolk!—The Atlantic<br/>

<br/>
The subjoined <i>jeu d'esprit</i> with the preceding heading in<br/>
magnificent capitals, well interspersed with notes of admiration, was<br/>
originally published, as matter of fact, in the "New York Sun," a<br/>
daily newspaper, and therein fully subserved the purpose of creating<br/>
indigestible aliment for the <i>quidnuncs</i> during the few hours<br/>
intervening between a couple of the Charleston mails. The rush for<br/>
the "sole paper which had the news," was something beyond even the<br/>
prodigious; and, in fact, if (as some assert) the "Victoria" <i>did</i><br/>
not absolutely accomplish the voyage recorded, it will be difficult<br/>
to assign a reason why she <i>should</i> not have accomplished it.]<br/></p>
<p>THE great problem is at length solved! The air, as well as the earth and
the ocean, has been subdued by science, and will become a common and
convenient highway for mankind. <i>The Atlantic has been actually crossed
in a Balloon!</i> and this too without difficulty—without any great
apparent danger—with thorough control of the machine—and in
the inconceivably brief period of seventy-five hours from shore to shore!
By the energy of an agent at Charleston, S.C., we are enabled to be the
first to furnish the public with a detailed account of this most
extraordinary voyage, which was performed between Saturday, the 6th
instant, at 11, A.M., and 2, P.M., on Tuesday, the 9th instant, by Sir
Everard Bringhurst; Mr. Osborne, a nephew of Lord Bentinck's; Mr. Monck
Mason and Mr. Robert Holland, the well-known �ronauts; Mr. Harrison
Ainsworth, author of "Jack Sheppard," &c.; and Mr. Henson, the
projector of the late unsuccessful flying machine—with two seamen
from Woolwich—in all, eight persons. The particulars furnished below
may be relied on as authentic and accurate in every respect, as, with a
slight exception, they are copied <i>verbatim</i> from the joint diaries
of Mr. Monck Mason and Mr. Harrison Ainsworth, to whose politeness our
agent is also indebted for much verbal information respecting the balloon
itself, its construction, and other matters of interest. The only
alteration in the MS. received, has been made for the purpose of throwing
the hurried account of our agent, Mr. Forsyth, into a connected and
intelligible form.</p>
<p>"THE BALLOON.</p>
<p>"Two very decided failures, of late—those of Mr. Henson and Sir
George Cayley—had much weakened the public interest in the subject
of aerial navigation. Mr. Henson's scheme (which at first was considered
very feasible even by men of science,) was founded upon the principle of
an inclined plane, started from an eminence by an extrinsic force, applied
and continued by the revolution of impinging vanes, in form and number
resembling the vanes of a windmill. But, in all the experiments made with
models at the Adelaide Gallery, it was found that the operation of these
fans not only did not propel the machine, but actually impeded its flight.
The only propelling force it ever exhibited, was the mere <i>impetus</i>
acquired from the descent of the inclined plane; and this <i>impetus</i>
carried the machine farther when the vanes were at rest, than when they
were in motion—a fact which sufficiently demonstrates their
inutility; and in the absence of the propelling, which was also the <i>sustaining</i>
power, the whole fabric would necessarily descend. This consideration led
Sir George Cayley to think only of adapting a propeller to some machine
having of itself an independent power of support—in a word, to a
balloon; the idea, however, being novel, or original, with Sir George,
only so far as regards the mode of its application to practice. He
exhibited a model of his invention at the Polytechnic Institution. The
propelling principle, or power, was here, also, applied to interrupted
surfaces, or vanes, put in revolution. These vanes were four in number,
but were found entirely ineffectual in moving the balloon, or in aiding
its ascending power. The whole project was thus a complete failure.</p>
<p>"It was at this juncture that Mr. Monck Mason (whose voyage from Dover to
Weilburg in the balloon, "Nassau," occasioned so much excitement in 1837,)
conceived the idea of employing the principle of the Archimedean screw for
the purpose of propulsion through the air—rightly attributing the
failure of Mr. Henson's scheme, and of Sir George Cayley's, to the
interruption of surface in the independent vanes. He made the first public
experiment at Willis's Rooms, but afterward removed his model to the
Adelaide Gallery.</p>
<p>"Like Sir George Cayley's balloon, his own was an ellipsoid. Its length
was thirteen feet six inches—height, six feet eight inches. It
contained about three hundred and twenty cubic feet of gas, which, if pure
hydrogen, would support twenty-one pounds upon its first inflation, before
the gas has time to deteriorate or escape. The weight of the whole machine
and apparatus was seventeen pounds—leaving about four pounds to
spare. Beneath the centre of the balloon, was a frame of light wood, about
nine feet long, and rigged on to the balloon itself with a network in the
customary manner. From this framework was suspended a wicker basket or
car.</p>
<p>"The screw consists of an axis of hollow brass tube, eighteen inches in
length, through which, upon a semi-spiral inclined at fifteen degrees,
pass a series of steel wire radii, two feet long, and thus projecting a
foot on either side. These radii are connected at the outer extremities by
two bands of flattened wire—the whole in this manner forming the
framework of the screw, which is completed by a covering of oiled silk cut
into gores, and tightened so as to present a tolerably uniform surface. At
each end of its axis this screw is supported by pillars of hollow brass
tube descending from the hoop. In the lower ends of these tubes are holes
in which the pivots of the axis revolve. From the end of the axis which is
next the car, proceeds a shaft of steel, connecting the screw with the
pinion of a piece of spring machinery fixed in the car. By the operation
of this spring, the screw is made to revolve with great rapidity,
communicating a progressive motion to the whole. By means of the rudder,
the machine was readily turned in any direction. The spring was of great
power, compared with its dimensions, being capable of raising forty-five
pounds upon a barrel of four inches diameter, after the first turn, and
gradually increasing as it was wound up. It weighed, altogether, eight
pounds six ounces. The rudder was a light frame of cane covered with silk,
shaped somewhat like a battle-door, and was about three feet long, and at
the widest, one foot. Its weight was about two ounces. It could be turned
<i>flat</i>, and directed upwards or downwards, as well as to the right or
left; and thus enabled the �ronaut to transfer the resistance of
the air which in an inclined position it must generate in its passage, to
any side upon which he might desire to act; thus determining the balloon
in the opposite direction.</p>
<p>"This model (which, through want of time, we have necessarily described in
an imperfect manner,) was put in action at the Adelaide Gallery, where it
accomplished a velocity of five miles per hour; although, strange to say,
it excited very little interest in comparison with the previous complex
machine of Mr. Henson—so resolute is the world to despise anything
which carries with it an air of simplicity. To accomplish the great
desideratum of �rial navigation, it was very generally supposed
that some exceedingly complicated application must be made of some
unusually profound principle in dynamics.</p>
<p>"So well satisfied, however, was Mr. Mason of the ultimate success of his
invention, that he determined to construct immediately, if possible, a
balloon of sufficient capacity to test the question by a voyage of some
extent—the original design being to cross the British Channel, as
before, in the Nassau balloon. To carry out his views, he solicited and
obtained the patronage of Sir Everard Bringhurst and Mr. Osborne, two
gentlemen well known for scientific acquirement, and especially for the
interest they have exhibited in the progress of �rostation. The
project, at the desire of Mr. Osborne, was kept a profound secret from the
public—the only persons entrusted with the design being those
actually engaged in the construction of the machine, which was built
(under the superintendence of Mr. Mason, Mr. Holland, Sir Everard
Bringhurst, and Mr. Osborne,) at the seat of the latter gentleman near
Penstruthal, in Wales. Mr. Henson, accompanied by his friend Mr.
Ainsworth, was admitted to a private view of the balloon, on Saturday last—when
the two gentlemen made final arrangements to be included in the adventure.
We are not informed for what reason the two seamen were also included in
the party—but, in the course of a day or two, we shall put our
readers in possession of the minutest particulars respecting this
extraordinary voyage.</p>
<p>"The balloon is composed of silk, varnished with the liquid gum
caoutchouc. It is of vast dimensions, containing more than 40,000 cubic
feet of gas; but as coal gas was employed in place of the more expensive
and inconvenient hydrogen, the supporting power of the machine, when fully
inflated, and immediately after inflation, is not more than about 2500
pounds. The coal gas is not only much less costly, but is easily procured
and managed.</p>
<p>"For its introduction into common use for purposes of aerostation, we are
indebted to Mr. Charles Green. Up to his discovery, the process of
inflation was not only exceedingly expensive, but uncertain. Two, and even
three days, have frequently been wasted in futile attempts to procure a
sufficiency of hydrogen to fill a balloon, from which it had great
tendency to escape, owing to its extreme subtlety, and its affinity for
the surrounding atmosphere. In a balloon sufficiently perfect to retain
its contents of coal-gas unaltered, in quantity or amount, for six months,
an equal quantity of hydrogen could not be maintained in equal purity for
six weeks.</p>
<p>"The supporting power being estimated at 2500 pounds, and the united
weights of the party amounting only to about 1200, there was left a
surplus of 1300, of which again 1200 was exhausted by ballast, arranged in
bags of different sizes, with their respective weights marked upon them—by
cordage, barometers, telescopes, barrels containing provision for a
fortnight, water-casks, cloaks, carpet-bags, and various other
indispensable matters, including a coffee-warmer, contrived for warming
coffee by means of slack-lime, so as to dispense altogether with fire, if
it should be judged prudent to do so. All these articles, with the
exception of the ballast, and a few trifles, were suspended from the hoop
overhead. The car is much smaller and lighter, in proportion, than the one
appended to the model. It is formed of a light wicker, and is wonderfully
strong, for so frail looking a machine. Its rim is about four feet deep.
The rudder is also very much larger, in proportion, than that of the
model; and the screw is considerably smaller. The balloon is furnished
besides with a grapnel, and a guide-rope; which latter is of the most
indispensable importance. A few words, in explanation, will here be
necessary for such of our readers as are not conversant with the details
of aerostation.</p>
<p>"As soon as the balloon quits the earth, it is subjected to the influence
of many circumstances tending to create a difference in its weight;
augmenting or diminishing its ascending power. For example, there may be a
deposition of dew upon the silk, to the extent, even, of several hundred
pounds; ballast has then to be thrown out, or the machine may descend.
This ballast being discarded, and a clear sunshine evaporating the dew,
and at the same time expanding the gas in the silk, the whole will again
rapidly ascend. To check this ascent, the only recourse is, (or rather <i>was</i>,
until Mr. Green's invention of the guide-rope,) the permission of the
escape of gas from the valve; but, in the loss of gas, is a proportionate
general loss of ascending power; so that, in a comparatively brief period,
the best-constructed balloon must necessarily exhaust all its resources,
and come to the earth. This was the great obstacle to voyages of length.</p>
<p>"The guide-rope remedies the difficulty in the simplest manner
conceivable. It is merely a very long rope which is suffered to trail from
the car, and the effect of which is to prevent the balloon from changing
its level in any material degree. If, for example, there should be a
deposition of moisture upon the silk, and the machine begins to descend in
consequence, there will be no necessity for discharging ballast to remedy
the increase of weight, for it is remedied, or counteracted, in an exactly
just proportion, by the deposit on the ground of just so much of the end
of the rope as is necessary. If, on the other hand, any circumstances
should cause undue levity, and consequent ascent, this levity is
immediately counteracted by the additional weight of rope upraised from
the earth. Thus, the balloon can neither ascend or descend, except within
very narrow limits, and its resources, either in gas or ballast, remain
comparatively unimpaired. When passing over an expanse of water, it
becomes necessary to employ small kegs of copper or wood, filled with
liquid ballast of a lighter nature than water. These float, and serve all
the purposes of a mere rope on land. Another most important office of the
guide-rope, is to point out the <i>direction</i> of the balloon. The rope
<i>drags</i>, either on land or sea, while the balloon is free; the
latter, consequently, is always in advance, when any progress whatever is
made: a comparison, therefore, by means of the compass, of the relative
positions of the two objects, will always indicate the <i>course</i>. In
the same way, the angle formed by the rope with the vertical axis of the
machine, indicates the <i>velocity</i>. When there is <i>no</i> angle—in
other words, when the rope hangs perpendicularly, the whole apparatus is
stationary; but the larger the angle, that is to say, the farther the
balloon precedes the end of the rope, the greater the velocity; and the
converse.</p>
<p>"As the original design was to cross the British Channel, and alight as
near Paris as possible, the voyagers had taken the precaution to prepare
themselves with passports directed to all parts of the Continent,
specifying the nature of the expedition, as in the case of the Nassau
voyage, and entitling the adventurers to exemption from the usual
formalities of office: unexpected events, however, rendered these
passports superfluous.</p>
<p>"The inflation was commenced very quietly at daybreak, on Saturday
morning, the 6th instant, in the Court-Yard of Weal-Vor House, Mr.
Osborne's seat, about a mile from Penstruthal, in North Wales; and at 7
minutes past 11, every thing being ready for departure, the balloon was
set free, rising gently but steadily, in a direction nearly South; no use
being made, for the first half hour, of either the screw or the rudder. We
proceed now with the journal, as transcribed by Mr. Forsyth from the joint
MSS. of Mr. Monck Mason, and Mr. Ainsworth. The body of the journal, as
given, is in the hand-writing of Mr. Mason, and a P. S. is appended, each
day, by Mr. Ainsworth, who has in preparation, and will shortly give the
public a more minute, and no doubt, a thrillingly interesting account of
the voyage.</p>
<p>"THE JOURNAL.</p>
<p>"<i>Saturday, April the 6th</i>.—Every preparation likely to
embarrass us, having been made over night, we commenced the inflation this
morning at daybreak; but owing to a thick fog, which encumbered the folds
of the silk and rendered it unmanageable, we did not get through before
nearly eleven o'clock. Cut loose, then, in high spirits, and rose gently
but steadily, with a light breeze at North, which bore us in the direction
of the British Channel. Found the ascending force greater than we had
expected; and as we arose higher and so got clear of the cliffs, and more
in the sun's rays, our ascent became very rapid. I did not wish, however,
to lose gas at so early a period of the adventure, and so concluded to
ascend for the present. We soon ran out our guide-rope; but even when we
had raised it clear of the earth, we still went up very rapidly. The
balloon was unusually steady, and looked beautifully. In about ten minutes
after starting, the barometer indicated an altitude of 15,000 feet. The
weather was remarkably fine, and the view of the subjacent country—a
most romantic one when seen from any point,—was now especially
sublime. The numerous deep gorges presented the appearance of lakes, on
account of the dense vapors with which they were filled, and the pinnacles
and crags to the South East, piled in inextricable confusion, resembling
nothing so much as the giant cities of eastern fable. We were rapidly
approaching the mountains in the South; but our elevation was more than
sufficient to enable us to pass them in safety. In a few minutes we soared
over them in fine style; and Mr. Ainsworth, with the seamen, was surprised
at their apparent want of altitude when viewed from the car, the tendency
of great elevation in a balloon being to reduce inequalities of the
surface below, to nearly a dead level. At half-past eleven still
proceeding nearly South, we obtained our first view of the Bristol
Channel; and, in fifteen minutes afterward, the line of breakers on the
coast appeared immediately beneath us, and we were fairly out at sea. We
now resolved to let off enough gas to bring our guide-rope, with the buoys
affixed, into the water. This was immediately done, and we commenced a
gradual descent. In about twenty minutes our first buoy dipped, and at the
touch of the second soon afterwards, we remained stationary as to
elevation. We were all now anxious to test the efficiency of the rudder
and screw, and we put them both into requisition forthwith, for the
purpose of altering our direction more to the eastward, and in a line for
Paris. By means of the rudder we instantly effected the necessary change
of direction, and our course was brought nearly at right angles to that of
the wind; when we set in motion the spring of the screw, and were rejoiced
to find it propel us readily as desired. Upon this we gave nine hearty
cheers, and dropped in the sea a bottle, enclosing a slip of parchment
with a brief account of the principle of the invention. Hardly, however,
had we done with our rejoicings, when an unforeseen accident occurred
which discouraged us in no little degree. The steel rod connecting the
spring with the propeller was suddenly jerked out of place, at the car
end, (by a swaying of the car through some movement of one of the two
seamen we had taken up,) and in an instant hung dangling out of reach,
from the pivot of the axis of the screw. While we were endeavoring to
regain it, our attention being completely absorbed, we became involved in
a strong current of wind from the East, which bore us, with rapidly
increasing force, towards the Atlantic. We soon found ourselves driving
out to sea at the rate of not less, certainly, than fifty or sixty miles
an hour, so that we came up with Cape Clear, at some forty miles to our
North, before we had secured the rod, and had time to think what we were
about. It was now that Mr. Ainsworth made an extraordinary, but to my
fancy, a by no means unreasonable or chimerical proposition, in which he
was instantly seconded by Mr. Holland—viz.: that we should take
advantage of the strong gale which bore us on, and in place of beating
back to Paris, make an attempt to reach the coast of North America. After
slight reflection I gave a willing assent to this bold proposition, which
(strange to say) met with objection from the two seamen only. As the
stronger party, however, we overruled their fears, and kept resolutely
upon our course. We steered due West; but as the trailing of the buoys
materially impeded our progress, and we had the balloon abundantly at
command, either for ascent or descent, we first threw out fifty pounds of
ballast, and then wound up (by means of a windlass) so much of the rope as
brought it quite clear of the sea. We perceived the effect of this
manoeuvre immediately, in a vastly increased rate of progress; and, as the
gale freshened, we flew with a velocity nearly inconceivable; the
guide-rope flying out behind the car, like a streamer from a vessel. It is
needless to say that a very short time sufficed us to lose sight of the
coast. We passed over innumerable vessels of all kinds, a few of which
were endeavoring to beat up, but the most of them lying to. We occasioned
the greatest excitement on board all—an excitement greatly relished
by ourselves, and especially by our two men, who, now under the influence
of a dram of Geneva, seemed resolved to give all scruple, or fear, to the
wind. Many of the vessels fired signal guns; and in all we were saluted
with loud cheers (which we heard with surprising distinctness) and the
waving of caps and handkerchiefs. We kept on in this manner throughout the
day, with no material incident, and, as the shades of night closed around
us, we made a rough estimate of the distance traversed. It could not have
been less than five hundred miles, and was probably much more. The
propeller was kept in constant operation, and, no doubt, aided our
progress materially. As the sun went down, the gale freshened into an
absolute hurricane, and the ocean beneath was clearly visible on account
of its phosphorescence. The wind was from the East all night, and gave us
the brightest omen of success. We suffered no little from cold, and the
dampness of the atmosphere was most unpleasant; but the ample space in the
car enabled us to lie down, and by means of cloaks and a few blankets, we
did sufficiently well.</p>
<p>"P.S. (by Mr. Ainsworth.) The last nine hours have been unquestionably the
most exciting of my life. I can conceive nothing more sublimating than the
strange peril and novelty of an adventure such as this. May God grant that
we succeed! I ask not success for mere safety to my insignificant person,
but for the sake of human knowledge and—for the vastness of the
triumph. And yet the feat is only so evidently feasible that the sole
wonder is why men have scrupled to attempt it before. One single gale such
as now befriends us—let such a tempest whirl forward a balloon for
four or five days (these gales often last longer) and the voyager will be
easily borne, in that period, from coast to coast. In view of such a gale
the broad Atlantic becomes a mere lake. I am more struck, just now, with
the supreme silence which reigns in the sea beneath us, notwithstanding
its agitation, than with any other phenomenon presenting itself. The
waters give up no voice to the heavens. The immense flaming ocean writhes
and is tortured uncomplainingly. The mountainous surges suggest the idea
of innumerable dumb gigantic fiends struggling in impotent agony. In a
night such as is this to me, a man <i>lives</i>—lives a whole
century of ordinary life—nor would I forego this rapturous delight
for that of a whole century of ordinary existence.</p>
<p>"<i>Sunday, the seventh</i>. [Mr. Mason's MS.] This morning the gale, by
10, had subsided to an eight or nine—knot breeze, (for a vessel at
sea,) and bears us, perhaps, thirty miles per hour, or more. It has
veered, however, very considerably to the north; and now, at sundown, we
are holding our course due west, principally by the screw and rudder,
which answer their purposes to admiration. I regard the project as
thoroughly successful, and the easy navigation of the air in any direction
(not exactly in the teeth of a gale) as no longer problematical. We could
not have made head against the strong wind of yesterday; but, by
ascending, we might have got out of its influence, if requisite. Against a
pretty stiff breeze, I feel convinced, we can make our way with the
propeller. At noon, to-day, ascended to an elevation of nearly 25,000
feet, by discharging ballast. Did this to search for a more direct
current, but found none so favorable as the one we are now in. We have an
abundance of gas to take us across this small pond, even should the voyage
last three weeks. I have not the slightest fear for the result. The
difficulty has been strangely exaggerated and misapprehended. I can choose
my current, and should I find <i>all</i> currents against me, I can make
very tolerable headway with the propeller. We have had no incidents worth
recording. The night promises fair.</p>
<p>P.S. [By Mr. Ainsworth.] I have little to record, except the fact (to me
quite a surprising one) that, at an elevation equal to that of Cotopaxi, I
experienced neither very intense cold, nor headache, nor difficulty of
breathing; neither, I find, did Mr. Mason, nor Mr. Holland, nor Sir
Everard. Mr. Osborne complained of constriction of the chest—but
this soon wore off. We have flown at a great rate during the day, and we
must be more than half way across the Atlantic. We have passed over some
twenty or thirty vessels of various kinds, and all seem to be delightfully
astonished. Crossing the ocean in a balloon is not so difficult a feat
after all. <i>Omne ignotum pro magnifico. Mem:</i> at 25,000 feet
elevation the sky appears nearly black, and the stars are distinctly
visible; while the sea does not seem convex (as one might suppose) but
absolutely and most unequivocally <i>concave</i>.(*1)</p>
<p>"<i>Monday, the 8th</i>. [Mr. Mason's MS.] This morning we had again some
little trouble with the rod of the propeller, which must be entirely
remodelled, for fear of serious accident—I mean the steel rod—not
the vanes. The latter could not be improved. The wind has been blowing
steadily and strongly from the north-east all day and so far fortune seems
bent upon favoring us. Just before day, we were all somewhat alarmed at
some odd noises and concussions in the balloon, accompanied with the
apparent rapid subsidence of the whole machine. These phenomena were
occasioned by the expansion of the gas, through increase of heat in the
atmosphere, and the consequent disruption of the minute particles of ice
with which the network had become encrusted during the night. Threw down
several bottles to the vessels below. Saw one of them picked up by a large
ship—seemingly one of the New York line packets. Endeavored to make
out her name, but could not be sure of it. Mr. Osborne's telescope made it
out something like "Atalanta." It is now 12, at night, and we are still
going nearly west, at a rapid pace. The sea is peculiarly phosphorescent.</p>
<p>"P.S. [By Mr. Ainsworth.] It is now 2, A.M., and nearly calm, as well as I
can judge—but it is very difficult to determine this point, since we
move <i>with</i> the air so completely. I have not slept since quitting
Wheal-Vor, but can stand it no longer, and must take a nap. We cannot be
far from the American coast.</p>
<p>"<i>Tuesday, the</i> 9<i>th</i>. [Mr. Ainsworth's MS.] <i>One, P.M. We are
in full view of the low coast of South Carolina</i>. The great problem is
accomplished. We have crossed the Atlantic—fairly and <i>easily</i>
crossed it in a balloon! God be praised! Who shall say that anything is
impossible hereafter?"</p>
<p>The Journal here ceases. Some particulars of the descent were
communicated, however, by Mr. Ainsworth to Mr. Forsyth. It was nearly dead
calm when the voyagers first came in view of the coast, which was
immediately recognized by both the seamen, and by Mr. Osborne. The latter
gentleman having acquaintances at Fort Moultrie, it was immediately
resolved to descend in its vicinity. The balloon was brought over the
beach (the tide being out and the sand hard, smooth, and admirably adapted
for a descent,) and the grapnel let go, which took firm hold at once. The
inhabitants of the island, and of the fort, thronged out, of course, to
see the balloon; but it was with the greatest difficulty that any one
could be made to credit the actual voyage—<i>the crossing of the
Atlantic</i>. The grapnel caught at 2, P.M., precisely; and thus the whole
voyage was completed in seventy-five hours; or rather less, counting from
shore to shore. No serious accident occurred. No real danger was at any
time apprehended. The balloon was exhausted and secured without trouble;
and when the MS. from which this narrative is compiled was despatched from
Charleston, the party were still at Fort Moultrie. Their farther
intentions were not ascertained; but we can safely promise our readers
some additional information either on Monday or in the course of the next
day, at farthest.</p>
<p>This is unquestionably the most stupendous, the most interesting, and the
most important undertaking, ever accomplished or even attempted by man.
What magnificent events may ensue, it would be useless now to think of
determining.</p>
<p>(*1) <i>Note</i>.—Mr. Ainsworth has not attempted to account for
this phenomenon, which, however, is quite susceptible of explanation. A
line dropped from an elevation of 25,000 feet, perpendicularly to the
surface of the earth (or sea), would form the perpendicular of a
right-angled triangle, of which the base would extend from the right angle
to the horizon, and the hypothenuse from the horizon to the balloon. But
the 25,000 feet of altitude is little or nothing, in comparison with the
extent of the prospect. In other words, the base and hypothenuse of the
supposed triangle would be so long when compared with the perpendicular,
that the two former may be regarded as nearly parallel. In this manner the
horizon of the �ronaut would appear to be <i>on a level</i> with
the car. But, as the point immediately beneath him seems, and is, at a
great distance below him, it seems, of course, also, at a great distance
below the horizon. Hence the impression of <i>concavity</i>; and this
impression must remain, until the elevation shall bear so great a
proportion to the extent of prospect, that the apparent parallelism of the
base and hypothenuse disappears—when the earth's real convexity must
become apparent.</p>
