This is a small portable cooking stove, and is very ingeniously contrived. The patentee states in his prospectus of it, that " it boils water, prepares coffee and chocolate in a very superior manner, boils eggs, cooks a beef-steak or a slice of ham, all in less than ten minutes. For dinner, it will prepare soup, steam vegetables, and cook fish, chops, or steaks, at the same time; and for these one farthing's worth of fuel is sufficient." Fig. 1 is an external view, and Fig. 2 is a vertical section; a is a small cone of cast iron, having at the bottom a grating, on which is put the fuel (charcoal), broken into small pieces; below this is a small chamber b, perforated at its sides for the admission of air, and containing a small pan to receive the ashes, and also to light the charcoal by a piece of paper; the vessel c contains water, which entirely surrounds the cone; the next vessel e above is intended to be Fig.2 used as a steamer; it has in its centre a frustrum of a cone, the lower edges of which descend below the bottom of the vessels, and fit upon the cone beneath, so as to carry up the flue to the chamber above, which has open perforated sides, whence the vapours produced by the combustion escape.

On the top of the cone there is a valve for enlarging or diminishing the aperture, having a horizontal rod fixed to it, which passes to the outside of the vessel, as shown. The vessel over this, f, is, we suppose, a stew-pan, or something of the kind; it is heated by the hot air and direct influence of the fire; above this pan is placed in a cavity of the cover a small pot for warming small quantities of liquid. There are several appendages or vessels for peculiar purposes, such as the boiling of eggs, etc. which fit one over another in a similar manner to those described. The apparatus is proposed to be used on the breakfast or dining-table, to be taken in a carriage, in a boat, or carried by pedestrians.
