The first free and unfettered balloon voyage was performed very soon after the event mentioned at the end of the last chapter. It was a daring attempt, and attended with great danger.
A balloon made by Montgolfier was used. It was 75 feet high, 45 feet wide, and spheroidal in form—heated air being the motive power. The bold aeronauts, on this occasion, were the naturalist Rozier and the Marquis d’Arlandes, a major of infantry. From the gardens of the Château of Muetta they ascended on the 21st November 1783.
