Mechanics' magazine and register of inventions and improvements . ot far from Paris, forthe education of a corps of aeronauts, witli theview of intioducing balloons into armies as ameans of reconnoitering the enemy. But thisuse of balloons was soon laid aside, for, likeevery other, it must be attended with great un-certainty, as long as the machine has to obeythe wind. Among the French, Blanchard andGarnerin liave undertaken the greatest numberof aerial voyages ; among the Germans, Pro-fessor Jungius, in Berlin, in 1S05 and 1806, made the first. Since that time, Professor Rei-chard and his wife have become known by theiraerial excursions. Even in Constantinoplesuch a voyage was performed, at the wish andexpense of the Sultan, by two Englishmen, Barly and Devignc. Blanchard has renderedan essential service to aeronauts by the inven-tion of the parachute, which they caa use, in case of necessity, to let themselves down with-out danger. The arrangement of the parachute, with re-ference to its use for aeronautic purposes, maynow be more fully illustrated.. In the right hand figure, M. Garnerins appa-ratus is seen as it ascended from St. Georges^parade. A cylindrical box, about three feet inheight, and two in diameter, was attached by astraight pole to a truck or disc at the top, andfrom this was suspended a large sheet of linen, somewhat similar to an umbrella. The formit assumed on the descent of the aeronaut ieshown in the next figure. AVhen first cut fromthe balloon, it descended with amazing velocity, and those who witnessed its progress consider-ed the destruction of the aeronaut as certain;but after a few seconds the canvas opened, andthe resistance was so great, that the apparatusdiminished in its speed, till on its arrival nearthe earth it was not greater than would haveresulted from leaping a height of two feet. Amongst the unfortunate aeronauts we mayplace Major Money, who ascended from Nor-wich, under the full impression that the aerialcurrent Mould take the ball
