to be woven in a common stocking frame, or a frame upon the same principle, instead of the looin commonly used for felted cloths. When the cloth is taken out of the frame, list, taken from felted cloth, or made for the purpose, should be sewed round the edges, and then the cloth should be finished in the same manner, and by the same processes, as the felted cloths in common use are, when taken from the loom.

If found convenient, two or more pieces may be sewed together, and the list sewed round the whole.

The following are said to be the superior advantages which this new article possesses. Independently of novelty, there is ease, elegance, and durability; and it is a cloth, notwithstanding the transverse elasticity, more impervious to wet than any cloth ever made, void of artificial means to render it water-proof; a thread cannot be made to twill or run from the edges, even with the assistance of a pin or needle.

MR. JAMES GODDARD'S, (NEWMANSTREET, LONDON,) for a Method of Manufacturing a certain Description of Wooden Boxes, called Chip- Bores, or Pill Boxes, of all various Sizes and Shapes.

We have in the specification before us, drawings that represent views of all the machinery used for cutting wood into chips, veneers, &c. for making these boxes, or for any other uses. The knife, or cutting instrument, is made of platesteel, having the edge thereof bevilled, or ground only on the side of the face farthest from the wood intended to be cut, and the line of the said edge is sloped, or inclined to the line in which it is moved by the carriage, in an angle of about thirty degrees; in other words, the angle of slope in cutting is such, that the length of the said knife, in proportion to the breadth thereof, as six to one. This mode of operation will be understood by the following description:-By turning a handle, the carriage and its cutter, &c. are brought to the end of the machinery; the screws and nuts being in a prepared state, the wood nearly shaped to its proper size, is put into its place, resting upon a platform, and having its face a very little beyond the groove in which the cutter is made to move. The screws, &c. are now brought to act fairly upon the wood; and the carriage being drawn through its course, cuts off a slice, or shaving. The carriage is returned back,

and the handle turned so as to press the said piece forward in the way of the cutter. The carriage is again drawn forward, and the cutter takes off a shaving of uniform thickness, more or less stour, according to the quantity of motion produced by the action of the screws. By proceeding in this manner, the whole piece may be cut up, until a thin portion only remains, and the remainder of a number of pieces may afterwards be glued together, and then cut into shave ings, or slices, of the requisite thinness, as before. The tops and bottoms of the boxes are made by means of a seat and cutting-punch, worked by a fly-press in the same manner as metallic blanks are cut out for coins, buttons, and other works. Mr. Goddard cuts his pieces for making boxes into fit lengths by guages, as in the usual method, and he glues them up upon cylinders, or blocks, and then puts them to dry in frames adapted for the purpose.

MR. PENWARNE'S, (PANCRAS,) for ar Invention, or Process, for giving Statues, or other ornamental Works in Plaster, an appearance nearly rescin• bling Marble.

A so

The principle of this invention is to impregnate the said plaster of Paris with sulphate of alumine (alum,) which is done in the following manner. lution of alum in water is prepared in the proportion of one part of alum to three of water. The liquor is then made to boil, or is heated to a degree of teinperature sufficient to dissolve the alum. The plaster-cast previously dried, and finished off, is then immersed in the above solution, and suffered to remain therein from fifteen minutes to half an hour; it is then taken out and suspended over the vessel, containing the solution, and when cooled, some of the solution is dipped up and thrown over it, or applied to it by means of a sponge, or linen cloth, and which is continued till the alum forms a fine crystallization over its surface, of a due degree of thickness; when it is sufficiently dry, it may be brought to a proper deg ce of smoothness, or polish, by means of sand paper, or glass-paper, and finished by being rubbed with a fine linen cloth, slightly moistened with clean water. The vessels made use of in this business are made of wood, heated by steam introduced through a leaden pipe, from a boiler.

Specimens of this imitation of statuary marble, may be seen at No. 12, Picket

street.

Street. Hitherto the plaster-cast has been valued for the facility it afforded of producing cheap, correct, and faithful, copies of the finest works of the chisel; but it possessed no other advantages: its colour was unfavourable, it was liable to Soil from the touch, and from dust, and its fragility and softness rendered it next to impossible to clean it. The present invention is said completely to obviate these disadvantages, and the subject of it may be regarded as an intermediate step between the plaster-cast, and the expensive inarble. It possesses the beautiful whiteness and transparency of the finest statuary marble, and at the same time scarcely yielding to it in hardness and durability. It is not affected by the moisture of the dampest apartment; is less liable to soil, and as easily cleaned as

marble.

MR. JOHN CRAIGIE'S, (CRAVEN-STREET, LONDON.) for an Improved Kitchen Fire-place.

Mr. Craigie's invention, by which full two-thirds of the fuel now used will be saved, consists in the application of the powers of an air-furnace, to give heat externally, and in using sand, iron, or other dense bodies, to receive and retain such heat, to be employed for various useful purposes. A description of a fireplace upon the smallest scale, is as follows: The foundation is of stone, or brick, four feet in length by two feet eight inches in breadth, and about twenty inches in height: at one end in 'the front is to be placed the chimneygrate, eighteen inches wide and six deep. On the foundation, in the centre, at nineteen inches distant from each other, are to be raised two sides, in stone or brick, the whole length thereof, about eight inches in height on these

sides is to be placed a pan, five or six inches deep, of cast-iron, of size to cover the whole, with rims to rest on the sides, but leaving a small space of about half an inch vacant from each side be low: the pan is to be raised above the. basis, so as to leave an aperture throughout, of about an inch and a half; at the end of the furnace, opposite to the fire grate, the aperture will terminate in a flue of brick, or iron, to, convey the smoke into the chimney of the house, which flue should be furnished with a register: a plate projecting from the lower end of the pan, will form the top of the fire-place, of eighteen inches by six or eight; the sides will be formed of tirebricks; the back made likewise of firebrick, will ascend towards the top, in a sloping direction under the pan. A fraine of iron is to be placed to receive the door or front, which is to be about eighteen by sixteen, so as to cover the ash-pit four inches, and to be about twelve inches above the grate for the fire-place, in front of which there should be an inner grate, five or six inches high; this door must have in the lower part of it, that is, at about one inch and a half from the bottom, a small door of about three inches wide by two in depth, to furnish air through the ash-pit. The iron pan being filled with dry sand, will form a sand bath, with heat sufficient, according to the depth to which the vessel is placed in it, for all ordmary purposes; and being once heated, will retain the heat for a considerable time, especially if the doors are kept close shut: the plate or front will serve for broiling or fiving. Roasting may be performed in high perfection, before the door in font, even with the door shut; an oven for baking may be fixed at the flue. In roasting, a fire-screen should be used.

The superiority of iron for roofs in lieu of wood, in strength, durability, and expense, is exemplified in a roof lately constructed by the Aberdare Iron Company, and put up at Newport, Monmouthshire. covers a building 40 feet long, and 21 feet wide over the walls, and consists of seven main couples, two leading couples, and wall-plating, all of cast iron, wrought iron laths, screw-pins, &c. total weight 2ton, 4cwt. 2qrs. 20lb. being sufficiently strong to sustain the heaviest stone tile of this country, and is in itself lighter than one of wood, of which substance there is no one particle. The main couples are made in three pieces, the collar or tiebeam of which forms part of a circle, thereby giving much more head-room than is possible with wood, and holes are left in the same for the purpose of fixing ceiling-joists, making an handsome covered ceiling; it requires neither sidepieces nor rafters, the wrought-iron laths being a substitute for both. The whole roofing, after being fitted together, and taken to pieces again, at Aberdare ironworks, was put into one waggon, and conveyed to Tredagar iron-works, there unloaded into a train-waggon, and taken down the Sirrowy tram-road, through sir C. Morgan's park, to Newport, in twenty-four hours, a distance of thirty-six miles. It was then fitted together again, and fixed on the walls completely ready for the tiler in less than five hours, who, having no laths to prepare or nail on, can tile a roof in half the time it could be done on one constructed of wood. They are applicable to buildings of all sizes, can be put up at a much less expense per square than any other, and are, of course, far more durable.

The two following facts connected with the migration of swallows, have been communicated by a correspondent to a respectable contemporary publication:-

In

In the village of Merton, in Oxfordshire, young swallow was caught about four years ago, and a very small light bell fastened round its neck by a thin band of leather. It was turned loose, and remained about the spot till the Michaelmás following, when it disappeared with its fellows. Next spring the bell was heard among the first arrivals; and the bird remained till the end of the season. He again made his appearance the third season; but his music ceased about the middle of the summer, from which it is conjectured that he had attracted the attention of soine person and was destroyed. The second fact, which rests on the authority of a clergyman resident near the spot, is, that many thousand swallows have been taken from the sandpits and cliffs on the south-west coast of Anglesea in a torpid state, during severe weather. It is stated to be a common observation of the country, that as the days grow shorter and colder, the swal lows become more numerous, which is accounted for by the arrival of strangers to take up their winter quarters.

Considerable quantities of poppy seeds have lately been bought up in different parts of the country, and the expressed oil from them sold at the price of Florence oil. Major COCHRANE, of Haddington, was the first person who stated the advantages arising from the cultivation of poppies, and that seven ounces of fine salad oil were furnished by expression from two pounds of the seed.

The success of the various institutions for the relief of the indigent blind, has suggested the idea for the relief of the opulent who labour under the privation of sight, on a plan similar to that by which M. Hauy at Paris, some years ago, taught them reading, writing, arithmetic, music, and the rudiments of the sciences in general. At the concluding lecture for the season at the Royal Institution, the large Voltaic apparatus, consisting of 2000 double plates, four inches square, was put in action for the first time. The effects of this combination, the largest that has been constructed, were of a very brilliant kind. The spark, the light of which was so intense as to resemble that of the sun, struck through some lines of air, and produced a discharge through heated air nearly three inches in length, and of a dazzling splendour. Several bodies, which had not been fused before, were fused by this flame: the new metals discovered by Mr. Tennant, iridium and the alloy of iridium, and osmium. Zircon and alumine were likewise fused; char

coal was made to evaporate, and plumbago appeared to fuse in vacuo. Charcoal was ignited to intense whiteness by it in oxymuriatic gas, and volatilized in it, but without being decomposed. A large Leyden battery, containing twentyfour coated jars, was charged by a mo mentary contact of the wires, to a degree that required from twenty to thirty turns of Nairne's machine of eight inclies dia meter. All the electrical phenomena of the passage of electricity to a distance, the discharge through a Torricellian va cuum, the attractions and repulsions of light bodies, were demonstrated in a distinct way by means of this apparatus, It is hoped that the application of so powerful an instrument, and such easy methods of producing the most intense heat, will lead to some new facts in analytical science.

At a late meeting of the Royal Society was read the translation of a paper by M. DELILLE, describing the real nature and properties of the celebrated Bohan Upas, or poison-tree of Java. The author, a French physician, and a member of the National Institute of Egypt, trans mitted this paper from the East Indies to the Royal Society, by an English lady. The botanical account of the plant in question he received from one of the French naturalists who accompanied Cap. tain Baudin, and who resided some time in Java, where he visited the interior of the country, and with much difficulty prevailed on the natives to show him the different poison-plants, which they carefully conceal, for the purpose of using them in war. Hence the many

fabulous accounts that have been circu lated respecting the fatal influence of the Upas; which, in the language of the Javanese, signifies vegetable poison, and is applied only to the juice of the Bohan tree, and another plant with a twisted stem. The former is a large tree, which the writer considers as a new genus;; the latter, yielding an equally powerful poison, is of the woodbine family. The Upas, or juice, is extracted by an incision made in the bark with a knife, and being carefully collected, is preserved by the natives to be employed in their wars. As to its diffusing noxious effluvia in the atmosphere, and destroying vegetation to a considerable distance around it, the absurdity of these stories is sufficiently. exposed by the fact that the climbing species requires the support of other plants to attain its usual growth. Dr.. Delille made several experiments with the upas on dogs and cats. An incision
