“I asked Mr. Coxwell to help me to read the instruments, as I
experienced a difficulty in seeing. In consequence, however,
of the rotatory motion of the balloon, which had continued
without ceasing since the earth had been left, the valve-line
had become twisted, and he had to leave the car and mount into
the ring above to adjust it. At this time I looked at the
barometer, and found it to be 10 inches, still decreasing
fast; its true reading therefore, was 9¾ inches, implying a
height of 29,000 feet. Shortly afterwards I laid my arm upon
the table, possessed of its full vigor, and on being desirous
of using it, I found it powerless; it must have lost its power
momentarily. I tried to move the other arm, and found it
powerless also. I then tried to shake myself, and succeeded
in shaking my body. I seemed to have no limbs. I then looked
at the barometer; whilst doing so my head fell on my left
shoulder. I struggled and shook my body again, but could not
move my arms. I got my head upright, but for an instant only,
when it fell on my right shoulder, and then I fell backwards,
my back resting against the side of the car, and my head on
its edge; in this position my eyes were directed towards Mr.
Coxwell in the ring. When I shook my body I seemed to have full
power over the muscles of the back and considerable power over
those of the neck, but none over either my arms or my legs; in
fact I seemed to have none. As in the case of the arms, all
muscular power was lost in an instant from my back and neck. I
dimly saw Mr. Coxwell in the ring and endeavored to speak, but
could not; when in an instant intense black darkness came, the
optic nerve finally lost power suddenly. I was still conscious,
with as active a brain as at the present moment whilst writing
this. I thought I had been seized with asphyxia, and that I
should experience no more, as death would come, unless we
speedily descended; other thoughts were actively entering my
mind, when I suddenly became unconscious as in going to sleep.
I cannot tell anything of the sense of hearing; the perfect
stillness and silence of the regions six miles from the earth
(and at this time we were between six and seven miles high) is
such that no sound reaches the ear.
