An experiment of Boyle's on the weight of Air gave birth to the new discovery of M. Montgolfier. Having conceived the thought of displacing the atmospherical air by one that was rarer, or lighter, he made use in the experiment of a piece of taffeta which was brought him from Lyons; he forgot the purpose for which it was intended, which was merely to line a suit of clothes; sewed it, and introduced into it forty cubic feet of air. The machine sprang out of the hands of Montgolfier, and mounted to the ceiling. It is not easy to describe his joy: he seizes the machine again with eagerness, and let it go in the garden, where it rises to 36 feet. But the air contained in it getting out at the border of the stuff, and the machine fell down again upon a tree. This unexpected success determined him to a second experiment. 

Some days after, a print appeared representing the moment of the ascent, in which but one and the same attitude could be given to all the spectators, that of having their eyes fixed upon the machine. Another print appeared afterwards, the subject of which was the fall of the Balloon at Gonesse. To this engraving, which expresses the terror of the [[Parish]], the painter has added some strokes of imagination. It may be conceived , however, that the unexpected appearance of such a machine was calculated to give an alarm, especially to country people. An intelligent, or even learned person, seeing, for the first time, a globe of 12 feet in height upon the ground, and move itself there by leaps and bounds, would most surely hesitate to approach it.
