To MR. HENRY BROWN, of Derby, for Improvements in the Construction of Boilers, whereby a considerable saring of Fuel is effected, and Smoke rapidly consumed.-July 1821. HIS invention consists in the introduction of an additional tube to be filled with water by means of pipes passing from the boiler, which tabe, by being carried through the furnace under the boiler, causes an increased surface of water to be presented to the action of the fire, and thus effects an economy in the consumption of fuel; beside which, by causing an interruption to the direct draught of the fire, and thereby turning the flame, the smoke and gas emitted become consumed, and produce a more intense heat than would be otherwise occasioned by the ordinary combustion of the fuel, when the smoke and gas are suffered to escape. The same contrivance is applicable also to waggon-shaped boilers, and may be made to pass under them in a similar manner to that above described. It is also further proposed to contract the fire-place by constructing a case to contain water, which shall surround the fire, leaving a small aperture at the lower part of the back communieating with the flues, by which the unconsumed smoke and vapour may pass into the flucs, and round the boiler as usual. It is particularly observed, that the fuel should not be conducted to the back part of the furnace until its gas is fully consumed.London Journal. To To ALEXANDER GORDON, and DAVID GORDON, of Edinburgh; for certain Improvements and Additions in the Construction of Lamps, and of Compositions and Materials to be burned in the Lamps, and which may also be burned in other Lamps.-Jan. 14, 1822. The improvements and additions in the construction of lamps are intended for the purpose of burning alcohol or spirits of wine; the liquor obtained from wood, commonly called naphtha or spirit of wood; the essential oils or compositions of the above-mentioned spirits; with such of the essential oils as are most easily soluble therein, and generally for the burning of all combustible fluids which are inflammable at a low temperature, and which do not require a combustible wick to raise their temperature to a point at which inflammation would take place, or to continue their inflammation. The improvements consist in employing wicks, made of metal or glass, instead of cotton or thread, or any substance usually termed combustible; and for that purpose they prefer platina, gold, silver, copper, or glass, spun or drawn into very fine threads or capillary tubes, collected into a bundle, and surrounded by a piece of metal-wire gauze, or by a piece of fine metalwire bound round them in a spiral direction; or the wicks may be formed of metal-wire or tubes, or spun glass, in any way, and in any desirable shape, so that the effect of capillary attraction may be preserved sufficiently to raise or draw up the combustible fluid to the situation where it is to be inflamed. The wicks thus constructed, are inserted through a pipe or tube in the manner of common lamps with cotton wicks: they recommend that the top of the wick or wicks be covered by a cap when the lamp is not in use, to prevent the evaporation of the combustible fluid, and to prevent dust from settling on the wick. As the substances intended to be burned in the said lamps are extremely volatile and inflammable, they recommend that the orifice from whence the lamp is to be filled with the fluid may be situated at the greatest convenient distance from the wick or wicks. They further recommend that an air-hole may also be formed at the greatest convenient distance from the wick or wicks; both of these orifices to be closely stopped when the lamp is not in use. They usually have a cap which screws down to a shoulder to close the orifice from whence the lamp is filled, and pierce an air-hole at the second or third thread of the male screw, by which means the said airhole can be uncovered, by unscrewing the cap two or three turns, and without taking off the cap altogether, except when the lamp is to be supplied with inflammable fluid. The compositions and materials to be burned in the lamps, and which may also be burned in other lamps, are composed of alcohol or spirits of wine, with an admixture of certain essential oils, as for instance, oil of juniper, camphor, the essential oil of tar, and such other of the essential oils as are most soluble in alcohol, the relative proportions of the two fluids or materials being regulated according to the description of lamp for burning the same, or to the use for which it may be intended; nevertheless, the relative proportions of the fluids or materials above mentioned, they should recommend to be five, six, or seven parts of alcohol to one of essential oil; but these proportions may be varied according as circumstances may require, such as the strength of the alcohol or the use that is intended with the lamp. Alcohol by itself is nearly pure hydrogen, so that, when burning, it gives only a pale blue light; the essential oils when buruing give much light; bat, unless they are carefully burned in lamps peculiarly constructed, they produce much smoke, and would be apt to leave a considerable deposition of carbonaceous matter upon the wicks, whilst the composition described above will be found to give considerable light, without any sensible smoke, and leaving little or no deposit upon the wicks. Another of the compositions to burn in lamps is made with the fluid herein before mentioned, usually called naphtha or spirit of wood, and which fluid they combine with the essential oils in about the same proportions as above mentioned for the essential oils with alcohol. The patentees conceives that their improved lamps, with incombustible wicks, will be found economical, and have many advantages over spiritlamps as hitherto constructed, from the durability of the wick and the equability of the flame; nearly the same advantages will be found in the lamps when burning the essential oils, provided the lamps are constructed, be sides sides having metallic or glass wicks, according to any of the present known improved methods for consuming, as much as possible, the smoke; and their improved lamps, when supplied with the compositions above described, may be kept burning for a great length of time without any attention being paid to them, except to maintain the supply of combustible composition; which they conceive will render the lamp peculiarly valuable in many situations, particularly for sea-lights on places frequently inaccessible.-Repertory. NEW MUSIC AND THE DRAMA. Mozart's Celebrated Grand Symphony, adapted for the Piano-Forte, with Accompaniments for a Flute, Violin, and Violoncello, (ad libitum;) by S. F. Rimbault. 6s. THIS adaptation of Mozart's truly Its be ranked among the better descrip- "Yes, I have lov'd the Minstrel's the highest terms of this composition, it at least claims our favourable acknowledgment as a body of ingenious and soundly-constructed harmony. The passages of the air sometimes include intervals that are somewhat strained, the several parts of the quartett are put together with a skill that demonstrates the possession of much genuine science. If, on the whole, this composition would not sanction our pronouncing Mr. Major to be a great melodist, it would bear us out in saying, that he is a real master in the art of harmonic combination, and that he has given a lucid proof of his ingenuity in disposing of the materials he has employed. Constancy, a Canzonet, by George Vincent Duval, esq. 28. This canzonet is, in fact, a ballad of Duett for two Performers on the same 1s. two parts are not ill-arranged, nor do they display much science. It is, however, no trivial praise of the publication to say, that it is pleasant to the auditor; and, to the young performer, will prove a profitable practice. DRAMA. COVENT-GARDEN. Though the drama has evidently, since the commencement of the present season, assumed an interest of which it could not boast during the last, the two national theatres have not equally partaken of the advantage of this favourable change. The varieties presented to the public by the Covent-Garden management, and the talents displayed in the performances of Mr. Charles Kemble and Miss F. H. Kelly, in Romeo and Juliet, and Mr. Macready in Venice Preserved, and a diversity of other pieces, have been more successful, as serving to ensure the applause of their auditors, than as draw. ing splendid and crowded houses. Even the novelties of a new opera, in three acts, entitled Maid Marian, and founded on the humorous, spirited, and vivacions, novel of that name, (written by the ingenious Mr. Peacock,) and a tragedy, (from the pen of Mr. Shields,) called, the Huguenot, have failed of attracting that attention which was to have been hoped from the distinguished merit of the production from which the plot and incidents of the first was taken, and the tried and well-known talents of the author of the second. But the most elegant and enlightened, as well as the light and less refined, of our public amusements, are, it would seem, subject to influence of fashion; and that to deserve, is not always to ensure public patronage. Wo, how ever, would by no means be understood to say, that the theatre of which we are now speaking has absolutely become unpopular: we only mean to remark, that its success this season has not, hitherto, equalled its deserts; and to express our hope, that ere the arrival of the summer recess, the taste and patronage of the lovers of the drama will compensate for the partial neglect sustained by this elegant and well-appointed establish ment. агова, DRURY-LANE. This old where a Garrick and a Pritchard, a John Kemble, a Siddons, and a Jordan, have so renownedly exerted their powers, and conquered, or commanded, the passions of their auditots, continues its brilliant carcer; and by the very distinguished acting of Mr. Kean, Mr. Young, Mr. Elliston, and the high vocal pretensions of Mr. Braham, Madame Vestris, and Mrs. Austin, aided by the extraordinary precosity of histrionic abilities exhi bited by Miss Clara Fisher, promise to carry the liberal and indefatigable manager triumphantly through the season. The novelties produced at this theatre, in the divertisement called the Halt of the Caravan; and the, new three-act opera of A Tale of other Times, (in the latter of which, Mr. Braham, Mrs. Austin, aud Madame Vestris, almost surpass themselves,) have contributed, in no light degree, to the splendid success with which the ardent lessee is persisting in his efforts to gratify the town. The constellation of talents with which he has surrounded himself, seems to have put him in a condition to defy, at least for the present season, the caprices of fortune and of fashion, and to secure to the great concern with which he has linked himself and his interests, that favourable and lustrous result due to his abilities as an actor; and his taste, judgment, and assiduity, as a manager.
