We give illustrations of thesecelebrated balloons, and will now pass on to the morescientific portion of the subject and the ascents of and other aeronauts for the purpose of makingmeteorological observations, and the use of balloons forpurposes of observation in war. It appears that the first ascent for scientific investiga-tion was made in the year 1803. The aeronauts wereMessrs. Robertson and Lhoest. They ascended fromHamburg and came down at Hanover, and made mean-time several experiments with reference to the electricalcondition of the atmosphere, its influence upon a magneticneedle, and some experiments with regard to acousticsand heat.
