This novel experiment, which forms an important epoch in the history of the art of aeronautics, attracted universal attention, and Stephen Montgolfier, having soon after arrived in Paris, was requested by the Royal Academy of Sciences, whose sittings, immediately on his arrival, he had been invited to attend, to repeat the experiment at their expense. He gladly availed himself of their proposal, and speedily got prepared a large balloon of an elliptical shape, 72 feet high, and 41 feet in diameter. It was finished in a style of great magnificence, and elegantly decorated on the outer surface with beautiful and appropriate designs. When completed, it weighed 1000 pounds. As a preliminary experiment, it raised eight men from the ground, and, on the 12th of September, 1783, it ascended, in the presence of the Royal Academy, with a load of from 400 to 500 pounds; but, in consequence of an injury it received in rising from a violent gust of wind, it did not present the same interesting spectacle as the public experiment previously made, and, upon its descent, it was found to be so seriously damaged, as to be unfit for future experiments. A new one of nearly the same dimensions was, therefore, ordered to be made, to which was added a basket of wicker-work, for the accommodation of a sheep, a cock, and a duck, which were intended as passengers. It was inflated, in the presence of the king and royal family, at Versailles, and, when loosened from its moorings, it rose, with the three animals we have named--the first living creatures who ever ascended in an aerial machine--to the height of about 1500 feet, an accident similar to what befell the other preventing it from attaining a higher elevation. It, however, descended safely with the animals, at the distance of 10,000 feet from the place of its ascent.
