Tebt TXI3 rt%% No. 1,415.] [No. 11, EXHIBITION EXPRESS.] THE EXHIBITION EXPRESS, Society of Arts of Class 10, which comprises all matters connected with the application of science, including bnll,,ons, anatomical preparations, piano fortes, chronometers, telegraphs, rind telescopes, Col. Lloyd stated that he had secured for that depart ment the best place in the building, as it was likely to prove most attractive, from the great amount of valuable property that would be exhibited there. In the division adjoining to Class 10, and within a stones throw of it, would be contributions exceeding one million sterling in value, consisting of jewellery and works in the precious metals. It was proposed that as far as convenient, the exhibitors should agree to adopt a general plan in the structure of the glass eases to cover their goods, and that where practicable they should be contained within one large glass case, each exhibitor being charged according to the number of superkial feet of space occupied. Those who had already providtd cant-subjected to this proposal asbeing made too late, and the matter was left to the decision of the exhibitors, who afterwards appointed com mittees for the purpose of making a proper display of the various articles to he exhillited. These com mittees have set vigorously to work, and have issued circulars to all the exhibitors, requiring them to state the exact dimensions of their contributions, whether glass eases have been provided, and whe ther they •pprove of the recommendnian to aLibit in a general glass case with others. Among the largest occupiers of space in Clan 10 are Mr. Dollond, Messrs. Watkins and Hill, Messrs. Knight and Sons, Mr. Broadwood, Mr. Erard, and Mr. Graham, the aeronaut. Plans of the proposed mode of arranging the counters, in which the parti cular spots assigned to each is marked, have been sent to those exhibitors to whom large portions of space have been allotted. THINGS TO BE EXHIBITED. FOR TILE WEEK ENDING SATURDAY, MARCH 8. PROGRESS OF TILE GREAT EXHIBITION. The lamenting% and plain fittings on the eastern side of the building are now nearly complete, and an opportunity is afforded of funning an approximate estimate of the amount of the contributions received Lam foreign countries. Many of the compartments are, ateyet, quite empty. No arrivals from the United States have taken place up to the present time ; and Brazil, Mexico, and Greece seem equally dilatory. From Norway and Sweden some small consignments have been forvrardccl, and Russia has already con tributed about 230 p pa ace kages. The quantity of goods which have building itself flew Austrian inconsiderable, the balk of the products of that country being retained in the dock warehouses until the spare act apart for their display is fitted up. A number of German carpenters are at present busily employed, and nearly the whole of the counters and cams m that portion of the Austrian compartment which is on the north side of the central avenue will be constructed by them. The most copious coatrihu tors hitherto are the Zollverein, Belgium, and Switzerland ; and in the Chinese compartment there is already a respectable assemblage of canes. France, how CWT. strange to say. is very much behindhand. The number of packages received from that country up to yesterday did not much exceed 120. This unusual inactivity on the part of our Gallic neighbours dues not, however, arise from indifference to the result of the friendly contest in which they have engaged. On the contrary, they are 'deeply impressed with the importance of the advantages which will be obtained by theme who arc victorious in the struggle, but certain misapprehensions respecting the amount of space placed under the control of their col ttttt iasionen: have effectually retarded the trams mine * to this country of their contributiona. The vases assigned ta France is exceedingly ample, em bracing in the whole about a hundred thousand square feet. and constituting little lens than a tenth of the whole exhibiting space of the building. Out of this 1410,009 feet, it was most distinctly inti mated by the executive committee, during their correspondenee with the French commission, that WOO feet should he deducted for walks and pit It would seem, however, that . the Frea m lrlocal committees dealt with their contributors as if the whole 100,000 feet were available for the display of their productions. No tice was given to persons who had obtained gold medals in their own expositions that an unlimited quantity of goods would be received from them, and silver medallists were led to believe that their treatment would be little less liberal. The na tural elinsequetice of these inconsiderate proceedings was an influx of eontributions, for the aceo 11111 l °da tion which the very ample space accorded was to tally inadequate. Upon the discovery of this unpa latable fact various devices were put in requisition by the French authorities to procure either an exten sion of their stows, or a curtailment of the extent of the :passages by . which they are traversed. The executive committee, however, were inexorable. They pointed to the fact that the original number of British contributors was 9,000, who, by the exercise of judicious weeding and selection by our local com mittees, have been reduced to 0,000; and they called on the French commissioners to exercise a similar system of vigorous compreasinn, and to reject everything not stamped with indisputable excellence of some kind. They are at present employed, we believe, in this work of pruning, and when the vast muss of contributions with which they have to deal shall have been reduced within the• requisite dimensions, the arrivals of French productions at the building will no doubt be large and frequent. Amongst the most interesting of the foreign arrivals during the last few days is a coke:cud figure of a diem in bronze which has been forwarded from Bava ria. and is the work of the sculptor F. von Miller. It is upward', of nine feet high, and will form one of the most remarkable objects in the Exhibition. In the British half of the building the visible signs of progress during the peat week are even more strikiccg titan in the foreign compartments. The stalls and fittings in the galleries are multiplying fast. and no small advance has been made in the adjustment of some of the heavy 'machinery which has arrived. The gouda now pouring in are, of course, of the most miscellaneous character. The light spring cart conveying some delicately eon- Km tell piety of mechanism, which is handed ice by its fabricator with as much care and tenderness RS if it acre a sick infant, alternates with the ponderous waggon sustaining some huge piece of machinery whose reluctant weight is dragged with difficulty to its destination by the united efforts of a dozen horses. On Thursday about five hundred tons weight of machinery arrived at the building. Amongst this was the celebrated Britannia hydraulic presw by which the lifts of the tubes of the railway bridge over the Menai were effected. some detached portions of this wonderful machine weigh no leas than 13 tons. Amongst the heavy machines fixed in their places are a machine for if heanued printing, a Krick-making machine. an enor mous but very beautifully constructed and powerful crane. and a smoke-consurning machine. 'I he foun dations of several ethers are in progron, and a strenuous activity prevails in the " machinery quarter" of the building —an activity by no means uuealled fur, when the shortness of time is taken into consideration, in which the fixing of the vast tunembhige of machines, destined fur exhibition, must be completed. The painting of the interior of the building is now preeeeding at a rapid rate, Messrs:, Fox and Hender son having entered into a fresh contract, by which they are bound to have it completed within a fort night. Judging from the progress male within the last few days, there is no doubt but that they will assure dish the task they have undertaken. The gallery railings are nearly all in their places, and the 'dairy:vas um quickly approaching completion. Carpenters are at present employed in constructing frames which are to be em lined en testing with allot the strength of the galleries. These frames are on castors. and each contains an compartments for the reception of alit shut: all moveable en any direction, and with the necessary amount of speed, with the greatest facility. A misc'once'ption has crept alined respecting the arrangements for the reception of holders of " season " ticket.• which needs correction. It is thought b y- venue that the holders of these pauses will ' be separated, atter their entrance. from friends who may prefer the plan of paying at the doors. 'The sepuration, however, if it can be called such where both parties arc within view of each other, will only- he a very brief one. the passages for the' two clamors into the building being quite near together. 'lle catalogues arc progirssing satisfactorily. Separate mcetinga of the exhibitors in cacti class have been convened, at which the general arrange ments proposed, have been explained he the gentle -111(41 who have the superintendence of the various departments; and suggestions made for the guidance of exhibitora in the display and preservation of their contributions, so as to produce the best effect. The names of the exhibitors having h; en called. those belonging to the different sub divisions of the class collected together, and discussed the plans suggested, and considered the means most advisable tolie adopted. At the meeting at the LILLY-ATV I'STING SPIRIT-LIT IL. Mr. Judge, of Hampstead, has sent in an instru ment, invented by himself, adapted to facilitate the opera tions of civil engineers and surveyors, by enabling them to take levels without the trouble :of adjusting-screws. The instrument adjusts itself by means of • weight fixed at right angles to the table whereon the theodolite rests, the table being hung in such • manner that the rod to which the weight is attached may be tree to assume a perpen dicular position wherever placed. The spirit level merely serves to show that the suspended table is obedient to the force of gravity, sad acts correctly. IMPROVED CRANK. A small model of an improvement in crank action has also been contributed by Mr. Judge. In the ordinary crank there are two points in the course of its revolution at which the mechanism connected with it would come to a dead lock, hut for the imps tus previously acquired, which carries the wheels beyond those points. A steam-engine, for instance, cannot be started when the piston connectesl with the crank is either at the top or the bottom of the cylinder. This inconvenience is obviated in steam-bnats and loco motives, by the employment of two engines, the cranks of which are placed at right angles, so that both together can never be in the position that renders starting impossible. Mr. Judge has endeavoured to remedy this defect of crank action, by attaching two connecting rods to the rod of the piston, our being shorter than the other. This contrivance, as applied to the model, certainly seems to overawne the difficulty, for in whatever position the piston rod is placed, the vertical movement up or down is not prevented. immuivon AND ORNAMENTAL WATCIIEO. Mr. Jones, of the Strand, contributes a watch which ob tains a dead beat of the second's hand with a single train of wheels. In the measurement of minute divisions of time it has been considered a matter of some imiortimee to make the seconds' hand indicate at once and distinctly each second as it passes, which cannot he done with the quivering beat of a common hand. To effect this object a second train of wheels; has been hitherto employed, but Mr. Jones contrives to dispense with this encumbrance, which tends to make the movement irregular, and in the gold watch to lie exhibited the dead heat is obtained by an alteration in the escapement of a single train. kErill mitArmis. The absence of frost during the paid winter will cause vast importations of the now almost necessary luxury of ice, and Wenham Lake will stand the ChalleC of being emptied by excavation unlexs the sun make speed to save snow of its water from deportation. The Wenham Lake Ice Company intend to make a display at the exhibition proportioned to the increased importuner of solid water, and to show iu a variety of handsome and convenient forms the best means of preserving ice from melting. The retrigerstom of the Wenham Lake Ice Company arc stated to be encased with a substance " impervious to caloric"—that ma fur a time. WIRE ItOPPII. The ropes and cordage lOd:iif:irnnds of twisted wires instead of hemp, possess the combined properties of flexi bility and strength, which render them well suited fur many purposes. Fur the rigging of ships this kind of cor dage has, we believe, been much used. tint object to which this mode of combining the strength of many wires, is intended to be applied is the construction of suspension bridges, fur which it possesses several noluisitcs. The adage, " that union is strength," is exemplified in the. peculiar application of the tensile power of metals. When a single bar of inn. is employed, however thick and apparently strung, there may be some unperceived Haw that baffles the calculations of the safest engineer, but by a combination of a number of smaller bars into one, this liability to break is prevented. or at least greatly diminished, fur if one should be defective, its weak ness is supported by the rest. For such a purpose, there fore, as the structure of suspension bridges, the plan pro misee to be successful, and when the " ropes" arc mode of the size intended, they have only sufficient flexibility to as sonic the proper course. The rigidity of such a bridge would therefore be greater than that u f one made of links, and its strength would be more uniform. A very tine specimen of a wire nips of this kind will be scut to the Exhibition by Messrs. Newall, ofMfillwall. It is made of six strands, each strand being composed of six twisted wires, or rods of iron, about tire-eights of an inch in diameter. This combined mass of twisted iron rods is about fifteen inches in circum ference. and the length of the specimen to be sent is six feet. In addition to this large specimen, space has been allotted for the exhibition of all kinds of smaller wire ropes by the same manufacturers. PHAXMACIP.VTICAL PRIPAIIATIONS. The members of the Pharmaceutical Society will exhibit an extensive and choice collection of drugs and chemical preparations. The care and skill M our operative chemists have been called into requisition in producing beautiful specimens; some of those of a crystalline form arc perfect illustrations of the proems of crystallisation, and show clearly how bodies held in solution arrange themulves during cooling or evaporation according to their specific characters. The plan on which the Pharmaceutical Society have proceeded we understand to have been this:—They made a claim as a body for a certain amount of space which has been apportioned to the several contributing members, whoa• =lns, will be attached to the articles they exhibit. and the whole contributions will be selected and arranged by members appointed for the purpose. yue UIOANTIC LIHIHITIUY CLOCK. Mr. C. Shepherd's electric cluck, which is to he placed over the south entrance of the transept, is now completed. The mechanism fur musing the monster hands is extremely simple, as the actual impelling power is a series of eleetro magnets which move the escapement sod push the minute hand Messiest at each Mat of the pendulum, by which the clectro magnets are brought into action. The minute hand is 16 feet lung. One of the peculiar features of Mr. Shep herd's electric clucks is the striking apparatus, which is an contrived that at each hour a separate series of electm magnets are brought into action and pull the hammer to the list. PRINCE ALBERT has manifested the deep interest which he feels in the operations of the Society for Improv ing the Condition of the Working Classes, by engaging to build, at his own expense, an Exhibition Model House, for four families, and to place the same in the stable-yard at the west end of the ca airy barracks, Hyde-park, immedi ately opposite the Exhibition building. The intended house is to be of hollow brick, with fire-proof &ors :and fiat roof; showing the applicability of these important prin ciples to houses of but very moderate dimensions. SeisoN Ttearts.--the printing of the " Season " tickets for the Great Exhibition has been entrusted to Perkins. Bacon. and Fetch, the bank-note engravers I and printers, of CO, Fleet-street. Upwards of 10,000 im pn.sions have, we believe. already been made and aura l' bered ; and it is expected the total will amount to 30,000. THE AsEMBERs OF TOE GREEK COMMISSION 111 Tired in London on SatunLiv, and have since taken possession of the spice in the Inn:Sing allotted to Greece. Among the articles -ant from tin eye are some very beautiful specimens of ancient and modern sculpture. IiNtiLAND'S " WOODEN WALLS" FOR —Reports arc already in circulation as to the naval display durimi the Great Exhibition. and various ship.' names have been quoted as likely to amenable at Spithead. We (Pelted Nerrice Gazette) have reason to believe that one of the finest and best equipped fleets, not only that foreigners ..er saw, but that Great Britain ever exhibited, will be formed at one of the home ports.movt probably at the Nor or Spithead, showing a total of nine veil-of-the-line and four first-class frigates, three screw line-of-battle ships, and three screw frigates, and one paddle-wheel frigate in all, twenty ships, from 1,000 tons, to 2,500 tons measurement. LONDON, SATURDAY EVENING, MARCH 8, 1851. ADDITIONAL LIST OF BRITISH EXHIBITORS. Ayr Town Council. A bell, adapted to carry a full sound • great distance, so as to warn vessels when incautiously approaching a dangerous rock or shoal. Adair and Co., Workington. Specimens of black lead pencil manufacture. Allis, J. H. Bristol—A new compound-pendulum clock. Bateman, Jonas, 101, Upper-street, Islington.—Two patent life boat.-11se frame of this boat is fastened to strong cross partitions. Ou the bottom framing of the boat strong water-tight cylinders are placed, the space be tween the bottom of the cylinders being tilled In with woes', to give them a solid resting. Strong metal screws pass through the entire übstance of the bottom of the cylinder and that of the boat-frame, to give strength and prevent any inclination of the cylinders to rise from the pre.ssure of the water beneath when immersed. The in terstices between each of the cylinders and the bout frame are filled up with cork. Each of the cylinders is intended to receive one person. A deck of the same di mensions as the bottom, but having perforated holes, cur responding in size and situation with the cylinders, is thrust down about three inches below the tops of the cy linders and on to the cork, and strongly fastened to the boat-frame. Other additions are made fur insuring the action of the boat, but the above are the principal fea tures of its construction. Brenner, J., Civil Engineer, Caithness—A model of the Great Britain steamship as she lay on the strand at Dun drums beg s with al the isgenamas apparatus and lever power by which Mr. B. achieved the feat of re moving and sending her afloat. The vessel, boats, &e., are made of tin, neatly executed and painted, and are set out with the chains, boxes, &c., used on the occasion. Booker, Workington. A ship's figure head. Budge, J. Sadler-street, Wells. A fau-sinsile, in pollard oa, of a chair which formerly belonged to the celebrated Abbot Whyting, of Glastonbury Abbey, and in which tra dition states he eat during his trial when he was con demned to death, in the reign of Henry VIII. The ori• ginal is in the possession of the Lord Bishop of Bath and Wells ; also a model of the above in ivory, on a scale of 11 inches to the foot. The latter stands on a carved ivory pedestal ; the design Of it is taken from a portion of the magnificent architecture in the Vicars' Close. Blaylock and Co., Carlisle. Improved turret clock. The improvements consist of a new adaptation of compound shafting and wheel-work, to give to a turret-tower or steeple a face on all the four sides. The faces of the clock consist of glass, the figures which show the hours are gilt on the inside surface, and consequently shielded from the effects of the weather. There is a contrivance for lighting up the four faces with gas light—perfectly self-regulating; it lights itself at the proper hour, viz., at sun-set cacti night, and nearly extinguishes itself at sun-rise each morning ; and it follows the setting and rising of the sun from the shortest to the longest day, and again from the longest to the shortest day, with only a half-yearly adjustment. Best, Thomas, Oldham. A measuring and dividing ma chine, capable of measuring to the hundred-thousandth part of au inch. Carmichael, J., shipwright, Workington. An oak chair. Cumin., James, South Molten. 1. Small h u r e ch oe f or general purposes; 2. Rorsehoe for general purposes on the ridge or flat •, 3. A one-way or turn-rest plough, im proved, for earthing up potatoes, eke.; 4. A one-way or turnrest plough, improve!; 5. Subsoil pulveriser ; 6. Horsehoe on the flat; 7. A set of diamond harrows for general purposes. Cooke% and 'cons, Warwick. The Kenilworth oak buffet. The central panel represents the triumphal entrance of Queen Elizabeth into Kenilworth-castle, in 1575. The meeting of the Queen and Amy ltobsart is shown on the right (or dexter) door panel, and the other our represents the interview of the Queen with the Earl of Leicester, when the earl declared his marriage with Amy Robseet ; the corner figures exhibit the four grand distinctive cha racteristics of the age, viz.:—Poetry, history, and the defenders of our country, both by sea and land crepre- Rented by Shakepeare and Sir Walter 1141eigh, Sir} rancis Drake, and Sir Philip Sydney. The small relieves upon the epandrils under the central compartment represent Orion upon a dophin, and a triton upon a mermaid, both forming a portion of the pageant enacted upon the lake around the castle. Clapham, John, Knaresborough. Muff, victorinc, urn stand. Cottrell, Brothers, Bristol—A specimen of paper-staining from blocks, and without manipulation. The stained paper, which isof colossal dimensions, formate portion of the wall of a room in imitative wood panelling. The groundwork is in imitation of a peculiar description of white deal, much used on the continent for the lining of rooms, and which, from its delicate and ivory-like character, is much better adapted for the purpose than the woods used in England. It is struck into panel with mouldings of light and dark oak, seemingly real, and a massive bordering of imitative oak carving, congests' of fruit and Indian corn. The fruits, he. stand out in hold relief, and the border is as exqui s itely fi nished as if care fully painted by hand. Cletus, Loch-street, Abereleen—A rotatory pump. The model for exhibition has a pipe attached to it of three inches diameter, and the rapidity of the action propels the water with such velocity that, although the pump be capuble of being wrought with the greatest ea, by a single individual, it discharges about seventy gallons pry minute. It may be used as a fire-engine, or a ship pump ; and eau be madc of any size, from the dimensions suitable to the pocket, to those requisite for draining a coffer darn. Cattanach, Union-street, Aberdeen—An instrument for taking the measurement of individuals for clothing. This instrument consist of a series of steel bands in a frame, that ore adapted to the human figure, and screwed into a position that indicates its form and size to a hair's breadth. Craig, Mr. Cornwallie-street, Glasgow—Novel smoke damper an d fire extinguisher. Weighing machines—namely, his own improved patent for general purposes, and one of Fairbank's patent for weighing and measuring the height of persons, suitable for the medical consulting room, public libraries, watering place's, lounges, &c. Also two smoke curers, fitted in imitation brick. work. The first, which is to be applied at the first construction of buildings, and consists of a chimney arch, is bevilled inwards and upwards, to receive a wedge-shape brick arching, thus allowing the cold air of the apartment to mingle gradually with the heated air iu the chimney; a frame is attached to this, determining the size of the mouth of the chimney. From this frame spring two supporters for the frame of damper, which can be put in and taken out at pleasure ; and as thew supporters guide the brick setter, they secure those gradual contractions in forming the throat so essential to a good going chimney. The ascend modification is contrived to obtain those gradual contractions which may have been neglected at first. A frame work is prepared as above for tiring in and deter mining the size of the mouth, and carrying the supporters fur the damper, which are to be built up behind, and rendered as effectual as if done at first. A small rod at the back of the grate, connected with a chain passing over a puller, and moved two inches, regulates the damper to the full size of chimney, or renders it perfectly tight, thus effectually stopping all hack smoke when no tires are used, and by shutting it, in case of the chimney being on fire, will speedily extinguish it. Dickens, Thomas, Middleton. Model of a warping mill. Dibble. Falkirk. An improved barometer. The smallest divisions on the dial are not less than one-tenth of an inch, though each of these answers to the thousandth of an inch in the rise or fall of the mercury. It presents two indexes—the one of the common range, and the other pointing out the thousandths of an inch. andsit has two registers, moveable from the sides. Above the dial is a superior looking thermometer, with the scales of Fahren heit and Reaumur. Evans, Sparks, Hungerford. An instrument invented by himself, to determine the tanning value of oak bark, and other materials. Ellis, Richard, Knaresborough. Carved ornamental ma hogany ease, containing the various mineral waters of Barna/me. Evans, Edwin, Oldham. Specimen of topography. Evans, Sparks, Hungerforel, Berks—A self-acting instru ment for determining the value of oak bark, divi dick and other tanning materials. The manufacturers are Metfff7Dring and Fage, Tooley-letreet. Elliott John, I/hie - ion-street, She& Id—Aweighing machine, the framework is a quadrant, placed against the wall ; from the right angle, at the top, projects horizontally the balance : and again, from the balance is a *mall curved . ' fulcrum, over which passes a chain to sustain the scale. There is also attached to the balance a weight and index, having much the appearance of a clock pendulum, which moves along the curve of the quadrant according to the ' weight of the substance in the scale. On the substance weighed being removed, the weight falls to its original : position with considerable f o rce, b u t, t o p revent i n j ury to the machine, a small spring is placed on the framework. which receives the force of the weight. At the end of the balance, Mr. Elliott has ingeniously fixed a small index. which gives the weight in Fr; nets kilogrammes, and other indices might be fixed to give the correspond ing weight of all nations. Foster, George, Retford. Two decorative panels. Fletcher, South St. Andrew-street, Edinburgh. A maho gany caw, containing models of a globe is its several stages of manufacture. Griffiths. Thomas, Wedneshiary—A Lilliputian gun. This weapon is not more than four and a half inches long, and weighing only a quarter of an ounce. It is a single barrelled percusaion, with all the modern improvements, and is capable of being loaded and fired with the utmost accuracy. The stock is of maple, and the barrel is twisted. The pereussion lock is composed of no lees than fifteen separate pieces, and some of these are so small as to he alniu.t imperceptible without the aid of a glass. Garthwaite, William, Darlington. Twelve tablets painted in imitation of different woods. Horn, Henry, shipwright, Portsmouth dockyard. A model of a 12-gun brig. It is on • scale 91 a quartos of an inch to a foot, and is fitted on a slip to launch, for the purpose ' of illustrating the manner in which the launching of a vessel is effected in the dockyard. The model is beauti tifully executed, and reflects great credit on Mr. Horn, particularly se it was made by candle-light, after the dock-yard working hours. It has been sent to the Great Exhibition of Industry. Harrison, Joseph, Preston. Three loom,. Two of them are wide (full size), and are constructed upon the most improved principle. The looms arc adapted for weaving cotton, woollen, flaxen, or silken cloths. One of them possesses llesars. Kenworthy and Bullough's patent weft stopping motion and temple, and Mr. James Bullough's patent loose reed and break. This loom is calculated for weaving not less than 210 picks per minute, and is the best adapted for the production of light goods. '1 he other loom has the same patent maims applied to it, except that, instead of having the loose reed and break of Mr. Bullough, it has the reed and break of Mr. Sellers, of Burnley, thereby rendering it more capable of weav ing heavy goods. It will run 200 picks per minute. The first is the weft motion and temple of Messrs. Kcnworthy and Bullougb, which, whenever the weft thread breaks or becomes absent by the action of a small fork in connexion with the setting-on handle, stops the loom, and prevents it going on without weft. The temple is a simple self-acting movement, consisting of an oblong box with a roller, fluted or cut almost like a tile, for a few inches at ea ch end, which, by the action of the cloth in weaving, is made to revolve, and keeps the fabric at mu uniform tension throughout ; and in compa rison.** the old kind of Simples is of great use to the weever, a. it dispenses with his attention end care entirely in that particuullar, and, moreover, keeps the sides , or " selvidges," of the cloth beautifully uniform and good, and frees them from tears and perforations. To the above there is the positive taking-up motion, which puts in any desired number of " picks " or threads per quarter inch, by the application of a small wheel containing a certain number of cogs or teeth; this makes the fabric of uniform thickness. The third power loom is one belonging to ancient times. It was made upwards of half a century ago. It is composed principally of wood, a little iron, and some stone and runs about sixty picks per minute (160 picks less than one of the new looms). Hornby and Co., Preston. Three model machines. They arc only half the usual size. Hick, Benj. and Sou, Bolton. Model of improved compound hydraulic press. This model shows the arrangement of an improved press, having four cylinders of such area as in the aggregate is equal to 2,500 tons pressure. Among the various advantages attributed to the plan are named, first, that the four cylinders may be worked either all together or two at once; and, secondly, that the desideratum of having sound castings for the cylinder is obtained, each of those weighing only two tons, whereas one evlinder equal in power, would weigh twenty tons as ordinarily made. This model has pumps and safety valves attached, so that it may be worked in the Exhibition; it is equal in power to a am-inch cylinder press. There is is two-horse high pressure engine, on the oscillating principle; and there is also a six-horse high pressure engine, on the direct acting principle, intended to work the machinery for spinning, &c., and for which Messrs. Benjamin Hick and Son arc sending shafting, pulleys, wheels, and firings; as also a series of ornamental framing and pillars for carrying the same. A portable smith's hearth, with fan for blowing the tire. An artillery forge, with fan for blowing the fire, which is adapted fur fixing upon a horse or mule, its weight being only about 1.:01b. An improved ball safety-valve, suggested and adopted by the late Mr. Benjamin Hick. A wheat-cleaning machine, intended for the purpose of cleaning wheat or other grain from smut. It consists of an outside conical cylin der, formed by a series of files, and an inside cylin der, formed by a similar series of files, leasing a space between them. The latter cylinder revolves freely on its axis, and the smut and other impurities are separated from the grain, and removed, the grain passing between the two cylinders whilst one of them is rapidly resolving. This machine will clean about 200 bushels of grain per hour. A model of a locomotive engine—a working model, made on a principle which was patented some years ago, by Messrs. B. Hick and Son; besides a full sized radial drill, and several other articles. A model of a pair of condensing steam-engines, of 120 Ilona , power each, made on the independent frame principle ; the cylin ders of 54 incites diameter, and 5 feet stroke. Haywood, James, Derby. Three stoves. The first is a burnished steel drawing-room stove, with ormolu orna ments, the hearth inlaid with Derbyshire porcelain in five panels, on which arc painted the following views of Derbyshire scenery: The High Tor, Matlock Ferry, Dovedale, Chee Tor, and a view on the Dement at Mat lock. The panels arc separated by burnished steel bend ing radiating from a centre. The china slabs were made by Messrs. locker and Co., Derby China Manufactory, and the painting executed by a Mr. Aplett. The second is a bright and black hall store, of novel construction, in which the high conducting power of iron is turned to account on a principle invented by A. R. Strutt, Esq., Helper; the inner case or cockle being cast with gnat number of ribs or webs of iron, which, by thin condnet ing power, abstract heat from the parts in immediate con tort with the fire. By this means the heating surface is inerea.sed, and the heat of the ordinary cockle is lowered down and diffused over so large a surface as to obviate the injurious effects of the ordinary hot air stoves. Hall and Co.. Derby. A chimney-piece. Hen...hall, George, Knarestiorougli. Fine sheeting. A shirt woven in tie without a seam. Hibbert, Tho mas, Knaresborough, draper. Hartley, Elizabeth, Knartsborough. Hearth rug, muff and boa, victorine, jacket, and bonnet. Hill, George, Knaresborough. Carriage rug, urn stand, bonnet. Hamilton, G. and P., Oldham. A cue thawing the dif fereut Mattes in the muuutaeture of flour, from the wheat to the biscuit. Sons, Hartford New Iron Works. A six-honk• high-pressure engine, on the direct acting prin ciple, intended to work the machinery for spinning.

A new mechanical propelling engine, from six to eight horse power, to supersede steam power, whether stationary, locomotive, or marine. It requires neither coal, air, or any chemical compound, to give the power; has neither funnel, boiler, condenser, tank, or tender, and appears very unlike any machine hitherto in vented. The expense of the engines will be less than those of steam ; the cost of working them will not be a twentieth part, and a much greater amount of speed may be obtained by them than by the best steam engines now in use. Made partly by engineers, and partly by white smiths, at Birmingham, 'Warwick, Leamington, and other places. Mason, John, Rochdale. Machinery for carding and spin ning wool : jacquard loom. Melling, Richard, Cuupland-street, Greenheys. Model of a roval railway carriage. The design is a manifestation of cultivated taste; and the execution shows equal skill M a manipulative point of view. It is on a scale of I} inch to the 6mt, and is supposed to be for the Great Western, brood gauge. The length of the platform is 3 ft. 9 in.; the breadth, 1 ft. 5 in. The length of the hotly of the carriage is 2 ft. 8 in. ; the breadth, Ift. 1 in. The interior of the carriage consists of three compartments—a centre or throne room, and a saloon at each end. The room in front of the carriage is supposed to be for the royal family and ladies and gentlemen in waiting, and this communicates by a door with the throne-room. The compartment at the rear of the carriage is for the remainder of the suite, and has no direct communica tion with the centre. The body of the carriage. is sur rounded by a promenade, encompassed by a ballustrade, supported by variegated pillars. At each corner of the platform is a British lion, with the paws fixed above the buffer rod., as if to keep them extended. The length of the centre room is 16 inches, that of the end rooms 7 inches. The royal chair is situate at the back of the centre room, and is surmounted by the royal arms, there being also the Prince of Wales's feathers, and the star and garter in other parts. The throne and couch; s are of mahogany, cushioned with light scarlet velvet, and trimmed with lace to match. The doors and compart ments are glued, and have moveable sashes. The body is painted a neat brown colour, and has circular ends. There is a door at each end, emblaeosecl with the royal [PRICE (DOUBLE SHEET) FOURPENCE. ' arms, and a door at each side, leading to the centre com partment, bearing the Prince of Walea's feathers. The roof is also surmounted with regal crowns. The hanging blocks arc carved in wood, with a scrollwork, having a tiger in the centre. The wheels are rimed with the stem and leaf of the vine; the axle-guards see also or namented. The buffer springs and rods, hearing springs and tension bars, are all in working order. The carriage is supported by eight wheels. At first sight, it would appear that a carriage of such length as to require four pairs of wheels would not be calculated to turn curves with safety, as the flanges of the wheels, being in a direct line, might interfere with the curved rails. This diffi culty is overcome by placing two pair of wheels near to each end of the carriage, leaving a considerable space in the centre. This arrangement allows it to turn a curve with nearly the same facility as if it hail hut two pairs of wheels, while it gives the advantage of much less oscilla tion, and adds greatly to the security ; fur if any particular wheel should fail—by the tire of the engine wheel break ing —the remaining wheel at that end of the carriage would still support it. The model is to be fixed upon rails, and covered by a glass case. Malady and Sons, II arwick—Glass cam of hats, showing the manufacture from the raw material through eight different stages to the completed article—va. raw ma terial for body, raw material for nappiug, body made, body proof'd, body rutted, body blocked, hat finished, hat complete. A second compartment shows manufac tured silk hats, present fashions, and new designs; venti lating cork and zephyr hats, fight and Wad* weigkin varying from 1 ounces upwards. A third compartment 'how, manufactured stuff rustic-a, novel style, Sarnbriro hats of all colours ' • also new designs in embossed felt bonnets. The glassease is in the shape of a dome. Mackenzie, J. S., Newark.—The triturator, a machine for grinding mercurial preparations, paints, printers' inks, and such articles as require continued friction and agi tation in their manufacture. It consists of a pan or mortar fixed in a wooden frame, with an apparatus so contrived that by turning a handle it gives to a heavy pestle a rapid rotary and at the same time a gradual alternate centrifugal and centripetal motion, so that the bottom of the pestle effectively acts upon the entire surface of the mortar. This ingenious machine was in vented at March, Cambridgeshire, in October last; it effects a saving of upwards of 500 per cent. in manual labour, while the preparations made by it are greatly superior in quality to the ordinary process. The want of such a machine 'has long been telt, fur while chemists' apprentices, in many cases paying high premiums, should be acquiring a competent knowledge of their business, their time is occupied, their faculties blunted, and their health impaired, with the laborious and monotonous work which this apparatus is adapted to perform. Another article to be exhibited by alr. filackenrie is the " Vulcan Spring." This is an extremely simple and efficacious door spring, applied at the top of the door, a short dis tance from the joint. No part of it is seen when the door is closed. It is not liable to lose its power or get out of order, and possesses many advantages over those at pre sent in use, while its cost is trifling. Moravian Establishment, Fulneek, Leeds—A piece of m edle work, by the ladies of this establishment. An inscription containing the names " Victoria and Albert," occupies the centre, and round that centre the names of the royal children, with their respective birthdays. The word', " Moravian Establishment, Fulneek, Leeds," are dis played on a medallion-shaped ground of carnation satin. Nammo, Falkirk. Specimens of fine glue. Oldfield and Sons, Ashford.

Portrait of 11.R.H. l'riuce Albert, embossed by hand from sheet silver, and several other specimens of chnsings and embeentinga. Space, wall 16 feet, counter, 8. Pace, Mr., Bury-1. A skeleton clock, 2 ft. 4 in. in height, which goes three years without winding up. This is ob tained by six powerful springs, the united force being equal to 2501b5. weight. They are enclosed in six barrels or boxes ; three are connected with chains to a fuzee on the right hand and three on the left. The power is thus concentrated in the pinion on the second great wheel, and is conveyed up the train of wheels and pinions to the pallets, which are connected a ith the pendulum. The power is here reduced to a few grains ; hut is quite suffi cient to keep the pendulum in constant motion. After the clock is first wound up the chain unwinds from the smallest part of the fuzee, three turns of which allow the barrel to revolve once in 210 days. This i. believed to be the slowest motion ever produced. It registers the day of the month, the number of weeks and years it has been going since it was last wound up. 2. A pyramidical skeleton timepiece, 23 inches in height, which good three months with once winding up. The dial is placed at the bottom of the clock, to show the motion of all the wheels, with Graham's dead-beat ex-aperient. The dial being placed so far below the centre, the hands are moved by a novel taut simple mechanism. 3. A barometer, of unique design, in highly-polished brass, containing three glass tubes, supported by scroll work. The centre tube is the barometer, and those on each sidle move an index, which rise and fall by turning a nut at the bag, of the stand. At the same time, by menus of wheel-work, the' turn the hands that arc on two dials, one fur ni g ht an d the other for day, indicating the state of the barometer. The whole is covered by a glass shade, 3 ft. high, sup ported on a pedestal from the floor. Peters, Daniel, Bristol—A specimen of West of England kersey, made from picked wools.

Painted and ornamental plates of glass, measuring 50 superficial feet' each. Reid, hornton-place, Aberdeen—A new machine for Mail ing, wringing, and mangling. It consists of an adapta tion of Mr. Its id's lever manFle, combined with a wash ing tub of a novel construction, into which the clothes and water are thrown, shut in, and thoroughly washed by machinery; after which by an equally simple process they are well wrung. This is managed by placing the wet clothes in • stout netted hag, and the bag, not the article that is in it, is twisted so that the water is thrown . . off, not by beings crewed out so mucias -- by simple - pressure. Ritchie, Peter, Kilmarnock—Two dozen hats and caps of different sorts. Reid and Humphries, the Misses, Bristol—A specimen of needlework and chenille embroidery, being a reproduction of Mr. F. Stone's picture "The Impending Mate." It contains 300,000 stitches. Ryder, William, Bolton, A patent forging-maehine. Robinson, James, Enaresborough. Ikath-rug, carriage rug, carriage slippers, muff and boa. Serymegour. Mr., Edinburgh—Model of a state bed, carved in pine and fir tree. The materials used in the uphol stery arc chiefly of Scotch manufacture, the blankets, which are of the finest Cheviot wool, being made by Mr. Crease, of Jedburgh. The bed is profusely but tastefully ornamented with various heraldic devices; on the head-piece the Scottish arms being beautifully em broidered, while on the foot-board are emblazoned the crowns ' coronets, and initials of all the 'loyal Famiy. The bed is ornamented by various appropriate dcsiAus. Spain, Mr., Ramsgate—A ba.,ket of Mowers three feet in diameter, in which every flower indigenous to British soil is formed of shells.

Stott, Abraham• Oldham. Sculptured figure of the Dis tressed Poet,•' or James I. of Scotland in confinement at Windsor. Skinner, John, Aberdeen—A momentary-motion life-boat. This boat, whether sharp or full built, possesses the power, under all interruption., of immediately resuming her original position. Allowing 6.74 lbs. as the weight p er cubic foot sustained by this or other air-tight vessel, we have, on Mr. Skinner's principle, in a boat whose dimen sions contain 247 cubic feet, a buoyancy sufficient to float • greater number than such boat can contain ; and the same buoyancy is maintained, whether placed with her gunwale upwards, on her side. or in any other disadvan tageous position. When inverted, she will float on hr r fore and after air-ess,s, thus preventing the contact of mid-ship gunwale with water, whereby little water being left to displace, the vessel is freed of that formerly insur mountable hindrance to self-righting; but from the boat's peculiar construction, the inverted position it were impos sible to retain. Ironmonger-lane, Cheap.ide. A specimen of ornamental penmanship, 3 feet square, illustrative of the qualities of " Tate's Exchequer Ink." Inman, Bansgste. Model of a luagor ready for ass. Twelvetridge, Jun., Mansfield. Carving, representing a scene from Othello. Woodruff, Thomas, Bakewell. A side-table 11. r Prince Albert.

Bowirbank was in the chair ; and the meeting, including time holy exhibitors of rank, included upwards of 'too t'olonel Lloyd detailed the objects for which the meeting had been con vened, and expressed the wish of her Majesty's commis sioners that sections of the committees for this department should be appointed, so as to be enabled to classify and arrange the various articles in proper and regular order. They also suggested that a uniform sine and appearance should be adopted for all the Cabes for articles included in this department, so that the whole of them might be brought into one grand and compact enclosure. home con versation ensued, in which various questions were put and appeared to be satisfactorily answered. It was then moved by Mr. Varley, and seconded by Dr. Bateman, "'that the general arrangement for the department of machinery at the Exhibition of 18.51, suggested by Colonel I.luyd, be adopted," which was put and unanimously agreed to.
