This airship appeared in 1848, and was designed by a man named J.M. Partridge. The envelope was cylindrical, tapering at each end, and was composed of a light rigid framework covered with fabric. The envelope was covered with a light wire net, from which the car was suspended. The envelope contained a single ballonet for regulating the pressure of the gas. Planes, resembling sails, were used for steering. In the car, at the aft end, were fitted three propellers driven by compressed air. Several short trips were carried out, but steering was never successful owing to difficulties with the planes and except in calmest weather she may be said to have been practically uncontrollable.
