The next great ascent took place at Milan, on the 25th of February, 1784, under the direction of the Chevalier Paul Andriani, who had a balloon constructed by the Brothers Gerli, at his own expense. We read that this balloon was 66 feet in diameter, and that the envelope was composed of cloth, lined in the interior with fine paper.
M. Andriani thought it best to place his fire contrary to general usage a little way above the mouth of the opening, and he found out that the activity of the fire was in proportion with that of the air which entered and fed it.
To descend to terra firma was then a comparatively easy matter, and it was safely accomplished. The fire, which in the case of the French balloons had dried, calcined, and almost consumed the upper part of the balloon, had no evil effect upon that of Andriani, which came down looking as fresh as if it had never been used.
Andriani did not deceive himself, for, sure enough, his first attempt did not come up to expectation. The reasons for this failure were the too great quantity of air which the fire drew in, and the unsuitable character of the fuel used. On the 25th of February, 1784, a second attempt was made.
Everything being in readiness, the machine was carried to Moncuco, the splendid domain of Andriani, where the first experiments were made; for this gentlemen knew that as the populace are impatient, they are also often un-reasonable, and jump to the hastiest and most inconsiderate conclusion when, in witnessing scientific experiments, any of the arrangements happen to be imperfect, and the results in any respect prove unsuccessful.
