209 wiij/is, h. London.—An organ consisting of threefows of keys and two octaves and a fifth of pedals. ThishiBtrument is built upon the German plan, viz., 8 feetManuals, and 32 feet pedals ; altogether it contains, in 77®Jop9, nearly 4,500 pipes, the largest being CCCC 32 feet,

smallest C § of an inch. The great and swell organs arcstayed by means of the pneumatic lever, exhibited in a^rtical position, and worked without the aid of additionalPressure of air. In the choir and pedal organs are intro-duced two newly-invented patent valves, over which thepressure of the air has but little influence. There is alsoIntroduced a patent movement in connexion with a com-P°hnd application of the pneumatic lever, which brings theJJ^mand of the instrument completely under the thumbsftl tJle performer, enabling him to draw stops in combinationel ^ hich there are 24 changes, thus rendering it, though^borate, perfectly manageable. The mechanism includes^eral novel arrangements, and in the various bellows

2? are five different pressures of air.lilt 0 1 >»nin, Mx. E. de, London.— Piece of mechanismi t rl n ded to represent the proportions of the human figure ;
