titions it will generally be best to ventilate them sepa-“ rately. For which purpose, let the corn be laid an equal' depth in all parts; then close all the holes towards the partitions, except of that to be ventilated, and all the holes on the side SS, and work the ventilators. The plugs may always be made to fit exactly by being bound with a little tow, if necessary.

Ventilating floors may also be formed of wire, perforated iron, tin, or bricks supported upon another floor, as described in this specification.

Stale and fusty corn, being spread thin and ventilated, as herein described, will be rendered much sweeter, and more fit for the sustenance of man, and the purposes of vegetation; and all cold and damp corn or seeds, which have been harvested in bad condition, may be much improved, and its natural colour preserved, by drying it upon a perforated wood floor, such as described in this specification, covered with tin, soldered so securely as to be air-tight in all parts, by means of steam or heated air, conveyed under the same; but it is not here meant to claim any exclusive right to any particular method of conveying steam or heated air under such perforated covered floor, but only to the construction of the floor itself. And I do hereby declare, that any person making or using a perforated wood floor, such as is described in this specification, and covering the same with tin, for the purpose of drying corn, seeds, or other merchandize, thereon, by means of steam or heated air conveyed under the same; any person doing so without my consent is deemed to encroach upon my patent. Having described my method of ventilating corn on board ships, and in granaries, and improving stale, fusty, and damp corn, seeds, and other merchandize, in the most exact manner I could, and so I think as is easy to be understood and practised

practised by any person, I now proceed farther to describe the rights granted by this patent as follows; that is to say: any person making or using a perforated wood floor in any of the ways or forms described in this specification, so as to be applicable to the purpose of ventilation, or forming or adapting any wire, perforated wood, iron, tin, or brick, floor, to, with, or upon, any other floor or materials, for the purpose of ventilation, or any other purposes herein mentioned, by supporting the same as herein described, or conveying air for the purpose of ventilation by an air-trunk and communicating pipes, formed and placed as herein described; any person doing so without my permission is deemed to encroach upon my patent. Also, any person making or using a ventilating bottom for ships, formed of hollow frames, as herein described, or shall make or use a ventilating machine or air-pump similar to the one described in this specification, is deemed to encroach upon my patent. But it is not here meant to claim an exclusive right to the use of wood, wire, iron, tin, or other floors, in the manner in which the same have been used before; but to a new method of constructing them, and of affixing, adapting, uniting, or connecting, them, to or with any other floor or materials, for the purpose of ventilation, and other purposes herein mentioned, in any of the ways or forms described in this specification. In witness whereof, &c.

Specification

Specification of the Patent granted to JOSEPH DE OLIVEIRA BARRETO, late of Lisbon, but now of Old Burlington-street, in the County of Middlesex, Esquire, and MARY DE LIMA BARRETO, his Wife; for a Method of treating and curing of Ruptures.

Dated August 30, 1802.

To all to whom these presents shall come, &c. Now KNOW YE, that I the said Joseph de Oliveira Barreto, in compliance with the said proviso, do hereby describe the nature of our said discovery, and the method of the treating and curing of ruptures to be as follows; that is to say: That our said invention and discovery doth consist of an ointment or salve, composed of the several drugs, and mixed and compounded in the proportion following; namely, one pound of incense, pulverized, one pound of almecago, one pound of turpentine, one pound of balsam of capivi, and one pound and a quarter of white or virgin wax, and in the same proportion for a greater or less quantity, always adding onefourth more of white or virgin wax. I likewise farther declare, that the best method of making this ointment is by first pounding the incense and almecago till it is reduced to a fine powder; then mix it with the turnpentine and capivi, repeatedly stirring it, for the space of three days, in a strong basin or bowl of earthen-ware ; then melt the wax to an oily substance, and when so melted all the other ingredients are then to be thrown in, when the whole is to be put on the fire, and stirred for a quarter of an hour. Then leave it for eight days; and after the expiration of those eight days it must be put on the fire again, and be well stirred for a quarter of an hour, and when cold it will be fit for use.

And,

And, lastly, I declare that the best method of using and applying the same, and the rules and regimen to be observed and attended to by the patients, are as follows. Cut a piece of leather the size of the rupture, or rather larger, and spread the ointment over it; then warm it a little, and apply it exactly upon the rupture. The patient, however, must first lie on his back, and if the intestines are down they must be returned; and when they are restored to their proper place and position, then the plaster must be immediately applied to the part, and then secured or fastened, by means of a truss, as tight as possible, and remain so for fifteen days; after which time the plaster is taken off, and a fresh one put on, for the space of fifteen days more, making altogether thirty days. But it must be perfectly understood, that after the application, namely, on the first day, the patient must go to bed, and remain there for twenty-four hours; and during the whole thirty days he must be extremely cautious not to ride on horse-back, nor walk fast, or any distance; that he should avoid going up and down stairs as much as possible, and should not lift any weight, or use any exertion, so as to extend the muscles: that he must also be very particular in his diet during the thirty days, and avoid eating butter, oil, and all similar substances; and also be extremely moderate in drinking, as well as in every other respect during all the before-mentioned period limited for the cure of the complaint in question. In witness whereof, &c.

Specification

Specification of the Patent granted to WILLIAM NICHOLSON, of Soho-square, in the County of Middlesex, Gen*tleman; for Machinery for the better and more expeditious manufacturing of Files.

Dated August 14, 1802.

To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said William Nicholson do hereby declare that my said invention is described in manner following; that is to say: My machinery consists in four essential parts suitably constructed and combined together; namely, First, a carriage or apparatus, in or by which the file is fixed or held and moved along, for the purpose of receiving the successive strokes of a cutter or chizel. Secondly, the anvil by which the file is supported beneath the part which receives the stroke. Thirdly, the regulating gear by which the distance between stroke and stroke is determined and governed. And Fourthly the apparatus for giving the stroke or cut. The four several parts aforesaid are supported by, or attached to, a frame or platform of solid and secure workmanship, either of wood or metal, or both, according to the nature of the work intended to be performed, and the judgement and choice of the engineer.

The carriage is a long block of wood, or metal, of the figure of a parallelipidon, or nearly so, having a portion cut out between its upper and lower surfaces to admit the anvil to stand therein, without coming into contact with the carriage itself. The said carriage is made of such a length that the excavation here described shall be considerably longer than the longest files intended to be cut ; and it is supported upon straight bearers from the plat
