Section 114. Respiration at so great an Altitude was perfectly free
and _easy_: _forced_ Trials being made for Information on that Point:
a Sensation of Levity seemed _rather_ to be communicated by the Air
to the Lungs: but this might be the Effect of the Imagination. It was
however a _curious_ Circumstance to find the Breath _not_ visible; the
Thermometer rising +again+ to 60. Nor did the Pulse seem to be quicker
than _usual_, in this elevated tho’ _inactive_ Situation.
[Sidenote: Thunder-Clouds as before.]
[Sidenote: Fairy Landscapes striking.]
115. The Perspective of a vast Series of Thunder-Clouds of a
_sulphúreous_ and _metallic_ Tinge, placing themselves in Ranks, each
beyond the other, in _bright_ and tremendous Order, and a Sort of
_Battle-Array_, beyond Conception _grand_ yet _beautiful_; coud not
pass _under_ him without Notice. The immense circular and visible
Distance of the +nebulous+ Horizon, extended +now+ 102 Miles _at the
least_ round the Eye, as already mentioned (Sect. 52); was a grand
Source of the Sublime. Nor did the contracted View of the Landscape
below fail, in Turn, to _regain_ an Attention to its _indiscriminate_
yet _pleasing_ Scenery.
116. +On a sudden+ he was called back to himself.
[Sidenote: Bladders _crackling_.]
Several of the +Bladders+, which were tyed round the Car, in Case the
Balloon shoud _alight on_ the Sea, and were +dry+ on the Outside, began
at the same Instant to +crackle+; being greatly distended by the Air
within. When pressed with the Hands and Fingers, they felt extremely
hard, and _ready_ to _burst_.
[Sidenote: Balloon _bloated_.]
On looking upwards at the Balloon, it appeared +greatly+ inflated: the
external Pressure of the surrounding Air being _much lessened_, in so
elevated and _rarified_ a State of the Atmosphere.
[Sidenote: Balloon _quilted_ by internal Pressure.]
117. The Balloon _pressed_ in an unusual Manner _throu’_ the Meshes of
the Net, quite round.
[Sidenote: Balloon shorter and broader.]
118. The Shape was much altered by this Distention of the Sides: and
its _perpendicular_ Diameter _shorter_ than before.
[Sidenote: Neck 8 Feet above the Car.]
119. The Neck or _Mouth_, which was _tyed_, had actually risen
_upwards_, and was +then+ near _eight_ Feet _above_ the Bottom of the
_Car_.
[Sidenote: Neck cut off in a former Excursion.]
120. It was not known till afterwards, that Mr. Lunardi on his second
aërial Voyage from Liverpool, had been obliged to cut off the _lower_
Part of the _Neck_, weighing upwards of _two_ Pounds and a _half_, in
order to lighten his Descent near Tarporley in Cheshire; and that he
had not _Silk_ sufficient to repair the Loss.
