claw; the two leaves reach to the ground, and the bed is only fix inches wide. The invention confifts in making two of the feet of the claw moveable, fo that when the leaves are down, the three feet ftand completely within the given fpace allowed by a bed of fix inches only; when one leaf is raised, a fupporter is to be pulled cut to fupport it, but the act of drawing the fupporter forward brings with it the foot of the claw. The fame way the other leaf is raifed and the fupporter and claw brought out with the Imalleft exertion. By uniting feveral of thele tables together, a table of any length and five feet wide is obtained, This is a carriage-lamp,and, like others, it can be made to any fhape or pattern. A description of a four-fided one will convey to the reader a proper idea of the inventien. Two fides are of course dark, with Jeflectors, the other two of glass. According to the old conftruction, there were Aliders before the glafs, which were the occafion of feveral inconveniencies. Mr. Dawion, to prevent the necessity of thefe, makes his lamp to confift of two parts, namely, the lamp itself, and a cafe, the latter is fixed to the carriage, and the former is eafily taken in and out, and being made exactly fquare, in the day time the dark fides are outwards, which prevents any damage happening to the glass; and at night the glafs is inftantly turned outwards, and candles or oil may be used at difcretion; another advantage is, that in cafe of any accident to the carriage by night, or of any thing loft, &c. the lamps may be taken very readily from the cates, when they make admirable handJanthorns. The high weights are caft in fand, or in a metallic mould, an opening being left in them of any form, of a fufficient deepnefs for the purpose of adjufting, and its furface large enough to contain the stamps; which opening is afterwards exactly filled with a piece of metal, to render the weight perfectly conformable to the fiandard. When the adjusting weight is too heavy, its weight is diminished by filing off part of its bottom, or by giving it feet, in order to leffen its fize, without reducing its height; or by placing below it, for the fame purpose, a bit of rolled iron more or lefs turned up at both ends. The metal used for adjufting and tamping, is fixed by two iron pins, put into the body of the weight when it is caft, which are to be riveted on the outside. In the flat weights the rivets go intirely through the weight itself. Although the adjufting weights may be made of any metal, or of compounded fubftances, yet Mr. Wilfon prefers wrought-iron or feel; the fubftitution of an indeftructible fubftance, in place of lead, being intended to prevent any deviation from the ftandard by common wear, while every thing else is fo contrived as to render it impoffible to mutilate the weight, without putting it in the power of any one who examines it, merely by ocular inspectic, to detect the fraud. The tops are made floping, that the duft may not lodge on them, and the edges are rounded off to prevent chipping. MR.AUGUSTUS FREDERIC THOELDEN'S for certain MECHANICAL APPARATUS for SUPPORTING the HUMAN BODY, or any PART thereof, more especially during the TIME of REPOSE, and for other BENEFICIAL PURPOSES. the cieling or upper part of the apartThe patentee propofes to fufpend from ment, or from the ufual framing or tefter of a common bedstead, a receptacle in which the human body, or any partof it, may der that this receptacle, or bed, may not be placed and fupported; and in oronly poffefs the advantage of being moved, placed, or fwung, in all directions, after the manner of a pendulum, with regard to its center or centers of fufpenfion, but likewife in order that the faid bed may be capable of a pleasant motion upwards and downwards, there is interpofed between the receptacle and centers of fufpenfion, a fpring or number of springs, of any figure and conftruction; though that in the fhape of a bow seems most pre ferabl ferable. In this cafe, one of the moveable extremes, namely, either the crown of the bow, or middle point of its ftring, is to be fixed to the upper hook or place of fufpenfion, and the bed itfelf is Exed to the other moveable extremity, viz. the middle point of the ftring, or the crown of the bow, as it may happen. And in order that the perion in the faid bed may produce at pleasure, the before-defcribed motion, a pulley is fixed at, or near, the center of fufpenfion, thro' which a cord is paffed, having one end of it attached to the bed, and the other at liberty to be drawn by the person or afThere fiftant, to produce the motion. are contrivances alfo to prevent the spring from giving way. This patent includes the conftruction of cradles, or fmall beds for children the method of fufpending fofas, chairs and other feats, with or without moveable backs, for the repofe of the human body. The fufpenfion is peculiarly adapted for the fupport of broken limbs, and various other ufeful purposes. MR. WILLIAM CHAPMAN'S (NEWCASTLE UPON TYNE) for the APPLICATION of certain SUBSTANCES, either feparately or combined, as a PRESER VATIVE of CORDAGE. It is a well-known fact, that common tar, unprepared, contains a quantity of vegetable acid, that is found materially to injure the cordage to which it is applied. Mr. Chapman's specification defcribes a method of extracting the mucilage and acid from tar, or any other relinous matter, before it is ufted. The rope-manufacturer may pursue the common proceffes of the tar-diftillers; or he may wafh the tar by agitations in cold, warm, or hot water; or he may boil it in water, which, in the action of ebullition, will agitate and wash the tar, and after it has parted with a fufficient portion of its effential oil, he may feparate it from the water, and afterwards pals his yarns through it, in fuch a degree of temperature as he may fee expedient: the effen tial oil may be faved, by putting upon his kettle the head of a ftill, with its appa ratus. After the tar is purified, the water muft be poured away, and the tar be boiled a little time to throw off any that may till remain mixed with it. The operation fhould be performed more than once, if great purity be required. This invention goes alfo to the carrying ward the improvement of the rope, im mediately previous to, or during the putting of its strands together. In the ufual method the top (an inftrument which feparates the ftrands until the inftant, of their combining into a rope) is made to flide uniformly, and without jerks, by rubbing a piece of tallow along each of the thrands. In the place of tallow, the following compofition is recommended, two parts of tallow and one of rofin. Thele proportions must be varied according to the temperature of the weather, &c. MR. JOHN WHITLEY BOSWELL'S (DUBLIN) for a MLTHOD of BUILDING or FABRICATING SHIPS or VESSELS for NAVIGATION. This method differs principally from that in ufe, by placing timbers or ribs, lengthwife or horizontally, inftead of vertically; and in making ufe of a frame, confiiting of a feries of triangles, in certain parts of the veffel, either to produce a greater degree of strength, with the fame quantity of materials, or an equal ftrength with a fmaller quantity. which it is expected, that much leis crooked timber need be used than is now employed, and the danger of ufing pieces cut across the grain proportionally diminished. By In this fpecification are given very particular directions for constructing veffels, and all the material parts of them, feparately, fuch as the head and ftern; the keel and kellon; the intervals between the horizontal ribs, and the decks. patentee adds, that it is his intention, that every part and thing, of and about a veffel, not defcribed by him, should be made or done according to the method in general ufe. The Belides the advantages of ftrength gained, expence faved, and a diminution of the neceffary confumption of crooked timber, Mr. Bofwell propofes,as an additional security, that the planks ufed, thould be grooved at their edges, in fuch a manner that when they are put together the grooves may be oppofite to each other; and that narrow flips of durable wood be placed in the faid grooves, fo as to lie across the seams, the whole length of the plank, but of fuch a fize as to leave fufficient space on the outside of them for caulking. is imagined that thefe flips will have the effect of valves, to prevent the farther progrefs of any water that paffes the oakum, tending to close the paffage more tightly the more they are preffed by the external water. It REVIEW OF NEW MUSICAL PUBLICATIONS. A fet of Ten Mifcellaneous Fugues, with Two Introductions and One Voluntary, for the Organ or the Piano-forte. Three of the Fugues by Handel, Three by Jofeph Diettenhofer, and Four, with the Voluntary, by John Sebaftian Bach. Chiefly intended for the Ufe of Organ yis, and respectfully inferibed to J. W. Callcott, Defter in Mufic, by J. Diettenbafer. 6s. F fome particulars of this excellent and ufe fur publication, we cannot give a better account than in the words of the fedulous and ingenious compiler's advertiment. "The firft fugue, in F major, of four fubjects, is adapted for the organ, with pedal, obligato, from the voice parts of the chorus of Let Old Titheus yield the Prize, in ALEXANDER'S FEAST. The fecond is a fugata in B miBor, alf by Handel; originally in two parts, to which Mr. Diet enhofer has here added a third. The introduction to the third fugata is fynonymous, with fome alterations by the compiler; and the fucceeding fagata in C minor is from Handel, with a few neceffary additions. The fourth, Non Nobis Damine, is a double fugue, with a cunter-fubject, invented in the double counter-point of the ortave. The fifth is of the fame defcription. The fish is a fingle fugue, without a counter-fubject, and is antwered by the fi th below. The feventh, with three fubjects, is adapted from a score of John Sebaftian Bach's. The eighth, ninth, and tenth fugues in C mjor, fharp, minor, and B minor, with the voluntary, are alfo from Bach. By this extract the reader will be enabled to judge of the value of the prefent publication, and how far the lovers of fine and genuine organ mulic are indebted to Mr. Diettenhofer's ingenuity, judgment, and industry. The truth is, that in this work he has furnished us with ano her noble collection of organic compofitions; and that it will prove a worthy companion to thofe excellent compilations with which he has before obliged the mufical public; and which, together with them, will form an invaluable body of this grand species of inftrumental mufic. "Fairies' Revels; or, Love in the Highlands." A Burletta and Ballas Dance. Performed at the Theatre Royal, Haymarket. Compofed by Dr. Arnold. 7s 6d. This last dramatic effort of the late ingenious Dr. Arnold, though not difinguished by any ftriking trait of originality, poffeffes a confiderable degree of that fpirit and fancy fo confpicuous in most of the MONTHLY MAG. No. 97. doctor's former productions: and bears the ftamp of real genius, though not, perhaps, in its meridian. The overture is a pleafing affemblage of new and felected matter, and includes the air of the Blue Bells of Scotland, with as pretty variations as we ever faw to that popular tune. The fong, "Come from the Eaft," fung by Mils Tirer, "What caules my Donald this Pain?" fune by Mifs Howells, and the ducit, "When Time, who ficals our Years away," are finooth and melodious; and the inftrumental movements depict the feveral fituations of which they are emblematical, with energy and truth. Two Sonatas for the Piano forte, dedicated to Mifs Young. Compojed by D. Steibelt, Efq. 65. Op. 48. This forty-eighth work of Mr. Steibelt's is every way calculated to fupport that reputation he has fo long and fo well me ited. The paffages are, generally speaking, florid and beautiful; and, in many inftances, perfeetly new. Each movement has a cha. racter of its own, and the happiness of ef fect, refuling from the intrinsic excellence of the whole, is not a little heightened by the judgment with which the feveral n ove. ments are contrafted. In juftice to Mr. Ste belt, we mu alo add, that we know of no publication better calculated to improve the piano-forte practitioner; and we do not doubt but Mr. Prefton, the publifher, will feel the effect of that qualifica tion in the faie. The celebrated PAS SEUL, danced by Mrs. Wybrow in the New Melo-drame, called the TALE OF MYSTERY. Composed by Dr. Busby Adapted to the Piano forte, with Variations, by J. Dury 15. 6d. Mr. Davy, in his variations to this fo july admired Pas Seul, has done ample juice to his original. The paffages are free and playful, yet every where aliufive to the theme; and their general conftruction is highly calculated to improve the finger of the practitioner. The Favourite Overture to the New Pantomime, called Harlequin's Habeas; or, the Hall of Spectres, as performed at the Theatre Royal, Covent Garden. Compofed by John Moorhead. cife for the piano-forte, to which it is here adapted, it claims attention, and will be found useful to young practitioners on that inftrument. "The Pilot that moor'd us in Peace." Sung by Mr. Dignum at the Concerts of the Nobility Compofed and inferibed to John Hiley Adding ton, Fjg by Thomas Cafier. The Words by John Taylor. 1s. 6d. "The Pilot that moor'd us in Peace," is a parody on "The Pilot that weather'd the Storm." In the words we do not find any thing but trite, common-place ideas, giving, in coarse verfification; and in the mufic, only a series of every-day paffages, and an effect common to vapid and flimfy compofition. "Mary, the Beauty of Buttermere." Sung by A Finale for Private Concerts. Composed by J. This finale is vocal, and confifts of five diftin&t parts, which are put together with a degree of addrefs highly creditable to Mr. Marth's judgment and knowledge in part compolitions. Some of the refponfes are neatly given, and the harmonic progreffion is in general found and judicious. "Dear Boy, throw that Icicle down." A Ballad, with an Accompaniment for the Pianoforte or Harp. Composed by W. Langsbow. The Poetry by Robert Bloomfield. 15. The melody of this ballad has the merit of characteristical fimplicity, but wants that fweet and rural turn of idea requifite to the paftoral style of compofition. Nothing can be more artlefs or more pictureque than the words; but mere fimplicity, (and that is all we trace in the mufic,) is infipidity. The Tamborina Dance, as danced by Miss Adams at the New Royal Circus, in the Grand Pantomime of the Eclipfe; or, Harlequin in China. Compofed by W. Ware. 15. This is a pleafant little compofition, and does credit to Mr. Ware's fancy. The Introduction is fo fhort that the piece may be faid to confift of but one movement; that movement, however, is pretty, both in its fubject and digretlive matter, and the whole forms an acceptable exercife for the piano-forte. "Saft as the Morning's blushing Hue." A fa vourite Ballad, compofed and fung by Mr Incleden, in the New Opera called Family Quarrels. 15. This ballad is compofed in the paftoral ftyle. Though without the aid of modulation, and thofe happy turns of idea, which can only refult from the combination of genius and fe ence, it poffeffes a fmooth and natural flow of paffages, and evinces natural tafte, and eafy conception.
