APPENDIX C

Proclamation published by the French Government on balloon ascents,
1783.

NOTICE TO THE PUBLIC! PARIS, 27TH AUGUST, 1783.

On the Ascent of balloons or globes in the air. The one in question
has been raised in Paris this day, 27th August, 1783, at 5 p.m., in the
Champ de Mars.

A Discovery has been made, which the Government deems it right to make
known, so that alarm be not occasioned to the people.

On calculating the different weights of hot air, hydrogen gas, and
common air, it has been found that a balloon filled with either of the
two former will rise toward heaven till it is in equilibrium with the
surrounding air, which may not happen until it has attained a great
height.

The first experiment was made at Annonay, in Vivarais, MM. Montgolfier,
the inventors; a globe formed of canvas and paper, 105 feet in
circumference, filled with heated air, reached an uncalculated height.
The same experiment has just been renewed in Paris before a great crowd.
A globe of taffetas or light canvas covered by elastic gum and filled
with inflammable air, has risen from the Champ de Mars, and been lost
to view in the clouds, being borne in a north-westerly direction. One
cannot foresee where it will descend.

It is proposed to repeat these experiments on a larger scale. Any
one who shall see in the sky such a globe, which resembles 'la lune
obscurcie,' should be aware that, far from being an alarming phenomenon,
it is only a machine that cannot possibly cause any harm, and which will
some day prove serviceable to the wants of society.
