An Important Discovery.

According to the Nott'mjha/n Jui'.nta/ a very groat improvement in the steam engine, amounting to a substantial discovery and invention, has just been patented by Mr Warsqp of that city. The improvement consists in forcing heated air into the boiler now in use—the air and steam together passing from the boiler to the engine. The inventor has a separate appar .tus for pumping and drawing the cold air through a coil of pipes, and so heating it before it enters the boiler ; but the cold air may be taken directly into the boiler, and bo made to t ike up its heat entirely from the water in it. The advantages ottered by this invention are stated to be threefold. “ First and foremost, a saving of more than 40 per cent, in fuel : secondly,-an increased amount of motive power compared with the ordinary steamengine ; and thirdly, a diminished supply of water for the boilers." A further advantage is also said to deserve attention, viz., “ that the action of the air on the water is very beneficial, keeping it in b constant perturbation, thus tending to prevent slating.” The same journal states that experiments have been made in Nottingham ; anil the results, as worked out by Mr Amos, the chief engineer- of the Royal Agricultural Society, and other practical engineers, verify the above statement of advantages. If these results should be confirmed by future trials, the importance of the. invention will soon bo felt—not the smallest advantage being, as the Nottingham- Journal points out, the increased length of the voyage it will enable steamers to make without re-coaling.
