Applications have, it is said, been made to the proprietors of the different places of entertainment in London, from whence balloon ascents take place, by an individual who wishes to make an ascent suspended 30 feet below the car, by magnetic attraction. The method by which he proposes to accomplish the feat is this: he possesses a magnet, the attractive power of which will sustain a weight of 150 lbs.; this is to be hung by a line 30 feet below the car; round his body is fixed an iron zone, which on being brought near the magnet firmly attaches itself thereto.
