This instrument is built upon theit p rillan . Plan, viz., 8 feet manuals, and 32 feet pedals;(ippMains 77 stops, nearly 4,500 pipes, the largest beings 'veb 32 feet, the smallest C | of an inch. The great anda Pnl ^ r S ans are played by means of the pneumatic lever,lion i y er tically, and worked without the aid of addl-ing, w ' nc l pressure. In the choir and pedal organs arethe <>auce( l two newly-invented patent valves, over whichin Pressure of the air has little influence ; also a patentth e Vanient in connexion with a compound application ofhnd Pneumatic lever, which brings the instrument entirelysev r P ei 'former’s command. The mechanism includesn ew arrangements, and in the various bellows thereSe nt l • different pressures of air. This organ is repre-e o in the opposite page as it stands in the Exhibition.

^ r °portl ^cchuoism intended to illustrate the different^Panded 11 ? ° P human figure: it admits of beinga c °lossal lr ° m ^ ze °f the Apollo Belvedere to that of

The external part of the figure consists of a series ofsteel and copper plates sliding upon each other, and keptin contact by screws, nuts, and spiral springs ; attachedto these plates, and within the figure, are metal slides,having projecting pins at their extremities: these pinsare inserted in curved grooves cut in circular steel plates:the curvature of these grooves being so arranged thatwhen the steel plates are put in revolution by a trainof wheels and screws the slides belonging to each parti-cular part of the figure are expanded or contracted incorrect proportion. The elongation of the figure isaccomplished either by sliding metal tubes, providedwith racks, and acted upon by a combination of wheels,or by screws and slides, as found most applicable for eachparticular part. Besides the general adjustments de-scribed, each part of the figure has an independent andseparate adjustment, by which it can be put out of itscorrect likeness to the Apollo Belvedere , and made torepresent the deformities or peculiarities of form of anyindividual. The varieties of figure and size of the humanbody are so numerous that it necessarily requires a greatnumber of movements to represent them. Some ideamay be formed of the number of mechanical combinationsincluded in the figure, from the following list of the partsof which it is constructed, vizi—875 framing pieces, 48grooved steel plates, 163 wheels, 202 slides, 476 metalwashers, 482 spiral springs, 704 sliding plates, 32 slidingtubes, 497 nuts, 3500 fixing and adjusting screws, and aconsiderable number of steadying pinions, &c., makingthe number of pieces, of which the figure is composed,upwards of 7000. It is stated that this invention couldeasily be made applicable in the artist’s studio; but thatits more immediate object is to facilitate the exact fittingof garments, more especially in cases where great numbersare to be provided for, as in the equipment of an army,or providing clothing for a distant colony; that personalattendance is not required, since there is adapted to thefigure, a new system of measurement which enables anyperson to take the exact size and form of an individual;and from the measurement so taken, the figure can beadjusted to represent correctly the person to be fitted,so that the clothing may be tried on, and, if necessary,altered with as much facility as if the original personwhose measure had been taken, were present.
