Green, 'apparently about two miles and a half
above a dense mountain of clouds, which presented the appearance of
impenetrable masses of dark marble, while all around us was shed the
brilliant rays of the setting sun. We continued to descend with great
rapidity, and as we approached the clouds, that velocity considerably
increased. At this time, so large had been our loss of gas, that the
balloon, instead of presenting to our sight its customary rotund and
widely-expanded form, now merely looked like a comparatively small
parachute, or half-dome, without any aperture in its centre. We
parted with at least one-third of our gas, and were as far beneath
the balloon itself as fifty or sixty feet.'
Apprehensive of difficulty in ascertaining the nature of the ground
toward which they were descending, from the darkness below them,
(though blessed, in their position, with a magnificent light,) they
hastened their progress, and landed in safety a few miles from
Maidstone, and twenty-eight from London; having been in the air one
hour and twenty minutes. But let us return to the unfortunate man who
had reached the earth before them.
The annexed engraving exhibits the parachute in the three stages of
the descent: first, immediately after the separation from the car;
next, at the time when the collapse took place from the weight and
pressure of the external atmosphere; and, lastly, when it approached
near to the ground:

After being detached from the balloon, it would appear that the
machine immediately lost its shape, by the breaking of the rim
which surrounded it, which was feebly constructed of tin. It was
the opinion of all the scientific gentlemen who testified at the
coroner's inquest, that the parachute was of insufficient strength,
and greatly inefficient for the purpose it was intended to serve.
Prof. AIREY, Astronomer Royal of Greenwich, who saw it from the
beginning, through a telescope of a twelve-times magnifying power,
states, that after leaving the balloon, 'he was quite sure that it
did not retain its shape for more than four seconds, for he put his
eye instantly to the glass, and found it in a collapsed state. He was
convinced there had been no turning over. Had it been turned over,
the basket would have been displaced. He observed the sides of the
parachute flickering backward and forward. His opinion as to the
efficacy of the construction was, there was not sufficient account
taken in such construction as to unavoidable disturbances, and the
tendency of the air was to force it in at the side, and the pressure
of the air would, in case of its getting out of shape, only aggravate
the evil, and the experiment must fail. This must therefore be
considered as a construction quite wrong, and he should have thought
that a person with common sagacity might have been aware of this.
With regard also to the tin tube, of which the circular ring was
formed, it was hollow throughout, it was without stops, which would
