Dr. Black reasoned that this being so, a hollow sphere filled with this gas, in a proportionate bulk, would rise in the air; and at a public lecture he successfully exhibited the experiment. The discovery of Cavendish and the theory of Black were not, however, carried to any practical result. To the brothers Montgolfier belongs the merit of having invented the balloon. They knew that atmospheric air expanded and became specifically lighter as its temperature was increased; and in 1782 they constructed a silk bag having a capacity of about 45 cubic feet, the sides and mouth of which were kept distended with slight hoops. A fire of paper being lighted below the mouth, the air within became rarified, and the balloon rose into the air. A public exhibition of a larger balloon, on the same principle, was made at Aunonay, in 1736; the balloon ascended to an altitude exceeding a mile, but remained in the air only ten minutes, when the air within having become cooled and dense--for in neither of these experiments did the machine take up the fire with it--the balloon came to the ground. Tho experiments of the Montgolfiers attracted great attention throughout Europe, and many speculative men studied the subject. At Paris, M. de St. Fond raised a public subscription for repeating the experiment of Annonay; and M. Charles and MM. Roberts, to whom the design was entrusted, constructed a balloon of considerable dimensions, which they filled with hydrogen gas, generated by pouring sulphuric acid on iron filings. The plan was imperfectly executed, but the balloon rose, and was retained at a distance of about 100 feet from the ground by ropes, and was paraded by that means through the streets of Pari. . .
