objections:-The joints being made entirely of brass will last a very short time, and will never work smocthly; the middle plate should be steel, but gun-metal or iron would be better than brass, and being made of sheet brass soldered together in three pieces the soldering makes the metal very soft; the tubes and joints are so weak that there is so much spring in them that it is almost impossible to take a correct length from the scale, and very difficult to describe a circle at all accurately. The points of the pens are so weak and badly fitted into the upper part, that the slightest pressure on either side will throw the nibs across and prevent the pen drawing a line, and being hollow on the inside of the nibs the pen will be useless when worn to the hollow, and very difficult to keep clean. The joints and screws of all the specimens are badly made; not one works evenly; the rules are incorrect; and the protractors have no zero marked on the fiducial edge; the scales being made of card, are subject to every variation of the atmosphere, more than wood or ivory; the point of the ever-pointed bow pencil is too long, and, if it wears away, will be too short to use. There are many other faults, which any person understanding the use of them will readily detect. May 15. Yours, &c., A MANUFACTURER. WARMING AND VENTILATING DWELLINGS. SIR,-Few people have wrought harder, more benevolently, and what is better, more beneficently, at the public service than Dr. Arnott; and his last endeavour to introduce an economical stove to consume smoke, applicable to all dwelling houses, is worthy of all praise. The principle of burning smoke, by supplying fresh coal fuel beneath, and not above, the incandescent mass, has probably always been known, but was, I believe, first promulgated in print by Count Rumford, who also first introduced the register, or upper valve, to regulate the draught of the fire and direct the radiation into the apartment. a 66 Doctor himself had proposed to attain. Some would gravely undertake to warm a church with a box a foot square; and occasionally made explosions with bituminous coal gas therein; and of all this ignorance the blame was attributed to Dr. Arnott. Had he taken a patent he might have dictated the exact construction, and regulated the price to his own satisfaction, without charging a royalty to the public, and the constant production of good stoves for fourteen years would have prevented the growth of the spurious varieties. Dr. Arnott has now produced an open stove similar to Cutler's, involving a better mole of construction, by the more careful exclusion of air below the coals, and a throttle-valve in the chimney, instead of the ordinary register, combined with back and sides of fire-brick, all elements of economical and good construction. Mr. Chadwick and other speakers dwelt strongly on the importance of Dr. Arnott having given this stove gratuitously to the public by not protecting it, as though a power in the hands of a benevolent man to protect his own invention must necessarily oblige him to tax the public for its use. I will venture to prediet that Dr. Arnott's repute wilk have the effect of bringing forth a large number of makers, who will disappoint the public and throw discredit on the plan. If Dr. Arnott had protected it-supposing it patentable and ensured the efficient manufacture, he would have better served the public than by merely making it notorious and leaving it at the mercy of all and sundry. If holding the patent without a wish for profit, he would thereby have ensured to the public the perfect article at a fair price. I doubt very much whether Mr. Chadwick and the whole Board of Health combined can easure the genuine article against spurious competition by any stereotyped form. What are the requirements to keep a sitting-room in a state of healthy warmth? 1. That the air be as nearly pure as possible. 2. That it be constantly changed as fast as breathed. 3. That it be in the condition of warmth best adapted to be breathed by the lungs according to the condition of health of the inhabitants of the apartment. 4. That the ingress of the fresh air be from above, and with its flow subdivided so as to prevent draughts injurious to the body. Sixty to seventy degrees will answer well for healthy persons with good circulation, or with the body in occa No contrivance in a single room can be so efficient as a system of warming the whole house, which will entirely prevent draughts in rooms. It is clear that draughts are produced by cold, dense air rushing in to supply a comparative vacuum caused by warm air of greater rarity. If the general air of a house be of one temperature these draughts will cease. Thirty years ago Cutler patented and brought into use 'gas stove," in which the day's supply of coal was placed in a box, sunk below the level of the hearth, be neath the fire-place, and projecting a little above it, so that the fire was kept very low. As the coals burned away at the top they were raised, with the moveable bot-sional movement. tom, by means of a winch, from time to time. The late Mr. Farey had one of these in use for many years, and it was never out of order. I have been informed that these stoves were applied to all the rooms in the Pavilion at Brighton, and they certainly were extending in use when the patentee commenced an action against some other makers, who were infringing his patent. The result was, that the patent was set aside by the judge, on the ground of want of novelty. The patentee thereupon, on his return from the court, gave orders to his foreman to break up all his patterns. He abandoned the trade, and left it in the hands of his rivals and the public. In a few years from that time the manufacture wholly ceased. It was alleged that the stoves were apt to get out of order, by the coals coaking and jamming in the box. It is quite clear that this must have been owing to imperfect manufacture. Fuel economising then lay in abeyance till Dr. Arnott produced his close stove, arranged to burn anthracite coal, either with a thermometer, or hand adjustment, to regulate the admission of air and the consumption of fuel, either by self-acting or other process. There is no doubt that, for the purposes for which Dr. Arnott intended it, this stove was thoroughly efficient; and in his work he specified the various modes of constructing it, with a suffic ent heating surface to warm a given number of cubic feet of air. But it was not patented; and under shelter of the Doctor's name, all kinds of people set up the trade of making the new stoves, promising far greater results than ever the Such a temperature may be obtained by the use of Dr. Arnott's close stove, or by hot-water pipes or vessels, or by steam pipes or vessels, taking care that in all cases the heat of the warming surfaces be not sufficient in intensity to decompose the impinging air, i. e., burn it, and that the surfaces be of sufficient extent to warm the air to the right temperature. All these are processes of private production of warm air; and, were we further advanced in the science of dwellings, they would probably be superseded by publicbuildings erected for the purpose of supplying pure warm air to a given number of dwellings, just as water or gas is supplied. The power that supplies the "hot air blast " to furnaces, conld easily be modified to produce a warmair flow to houses, with the greatest possible economy of fuel, with its entrance below and exit above. But, in addition to accomplishing the warming the general atmosphere of a dwelling to a constant summer warmth, there is another consideration. Persons of studious and sedentary habits have very rarely a perfect circulation of the blood. Sitting in a room, they do not inhale sufficient oxygen thoroughly to heat the blood, drive it to the extremities and back again to the heart. They labour under cold feet. In this condition the brain and nerves are not in the best state for mental operations, because the digestion is impaired, and impaired digestion is but another word for incipient paralysis. The common remedy for the evil of cold feet is to apply direct heat to them by foot-warmers, or by the radiant heat of an open fire, the latter being the most convenient and pleasantest. This process is in reality analogous to the artificial circulation of warm water in pipes by a furnace, the radiant heat acting as a furnace fir to the feet to drive back the blood to the heart. To obtain this radiant heat for the feet in the best mode, the practice has obtained of keeping down the firegrate as low as possible on the hearth. And this practice slowly arrived at from time to time, and empirically kept up, is founded on reason. The rays of heat that strike furthest into the room are those of an angle of 45° with the wall, i.e. the horizontal rays. Therefore, a grate level with the floor, and a low-fronted fender, would be best adapted to warm the feet. But it is urged against this that the lower the grate the lower are the draughts of air rushing across the floor to the fire, and, consequently, the colder the feet. But this is not the fault of the fire, but of the mode of feeding the fire with air. If the air be brought by a pipe directly below the fire, the draught may be adjusted exactly like a furnace, and, in such case, with the general air of the house warmed, there would be no draught whatever across the room. If the low position of the grate necessitated draughts, and the only object of the open fire were to warm the air, it would be better to set the fire-place half way up towards the ceiling. To make sure of obtaining the greatest possible amount of heat from the fire-place direct to the room, it is essential that the fire should be contained in an absorbent, and not in a conducting material—fire brick in preference to iron. The common register stoves of iron, commonly and carelessly set with hollow spaces behind the iron, are the most difficult to light, and the most effective to carry the heat up the chimney. The iron must be thoroughly warmed before the fire can burn well, or throw out heat. Fire-brick absorbs heat, and retains it for a long time, gradually giving it out. The register stove has its top made at an angle to refract the fire, but the black surface is of little use for this purpose, and the form is best calculated to throw out the smoke into the room. The true form for the upper part of the stove is the funnel-shape, with a throttle-valve in it, as Dr. Arnott has applied it, so as to regulate the exit of air, and, consequently, the draught, at will, extracting more or less heat, and consuming more or less fuel. The conclusion is that, for the purpose of supplying radiant heat with the least waste and the least inconvenience, a fire-brick stove, with a funnel top and throttlevalve, and a pipe from the external air to supply the fuel draught, is the best adapted. But there seems to be a fallacy in the notion that a large open-topped fire-place must of necessity cause an enormous waste of fuel. It is clear that some heat must be used in three ways: First to produce draught in the chimney; secondly, to saturate the clothing, furniture, and walls of the room; thirdly, to produce draught for ventilation. If more be used than is necessary, it is wasted. But if the heated air going up the chimney gives up its heat to the brickwork, that heat is available in warming the dwelling, and is not wasted. And it is possible that a rush of air passing up the chimney above the fire, and as it is called "cutting off the draught," may carry very little heat with it. The mode of ascertaining the waste of heat should be by the pyrometer or therinometer at the chimney top. The mode of building cottage houses with the chim ney-stacks in the centre, containing all the flues, is an illustration how heat may be economised which is apparently burned in waste. The chimney-stack in such case becomes as it were a huge German stove. "a As with Cutler's so with Dr. Arnott's improved Cutler's stove, there are two advantages-burning the smoke precisely as a candle burns tallow, with the fire above and the fuel below, and the power of turning up the fire and turning it down, as we increase or diminish the consumption of a gas burner. Whether the mechanical action is the best that can be devised, or whether it is liable to get out of order, are other questions, which time will prove. If not, improvements will be made, patented or otherwise, and the patented ones will thrive best, cæteris paribus, because individuals will work most earnestly at them. These stoves will answer best for offices, from their faculty of maintaining a fire in the owner's absence, and from not going out when neglected for hours; but they will answer better when constructed of fire-brick than of iron; and they ought to answer best, on Dr. Arnott's plan of totally excluding the air below, if the box be supplied entirely with coal-dust. How far they will work in kitchens, with an oven on one side and a boiler on the other, is a question, but there are sufficient advantages to induce the hope that the stove will not again be laid in abeyance, as in the time of Cutler, and that it will not be damaged by the injudicious praises of Mr. E. Chadwick, C.B., who seems bent on obliging every one to resort to it by order of the Board of Health, in order to prove his case of " saving of three millions per annum in the metropolis alone," by the economy of soap and the diminution in the number of clean shirts. Mr. Chadwick's mode of making deductions from the Preston strike closing the smoky factories, leaves out of the account the absence of washing shirts by reason of want of wages to pay for them, and it is to be hoped that no summary legislation by Lord Palmerston will be grafted thereon, or we may have a second fallacy like that of glazed tubular drain-pipes applied, rightly or wrongly, to all possible purposes. If Mr. Chadwick takes up a crotchet he holds to it tenaciously, and if he once publishes the banns of marriage between any stereotyped stoves and a new building act, he will consider it as an official patent of his own, and protect it accordingly. No conceivable nuisance of private patentees can compare with the nuisance of an irresponsible office held by Royal Authority. The private patentee can only work his individual crotchet, the official patentee can proclaim "Thou shalt have none other crotchet but mine." If Mr. Chadwick had his will, we should be all Prussianised,--no individual will would be left. He would be as one of the old Jesuit missionaries amongst the Indian tribes; all the laws would come out of his mouth; "and by the mass 'twould be sore law," from the vexed question of broken tubular pottery. We would rather trust to Dr. Arnott's patent than to Mr. Chadwick's officiality. He thus sums up: "The success of the old invention, now revived, and simplified, and cheapened, appeared to be so decisive as to leave nothing now to be desired but extensive and practical measures to ensure its adoption." That is to say, a New Building Act, worked by the Board of Health, with Mr. Chadwick for official refereo, and the patterns of all things, and also of some others, hung up in his office for all future time. From all which deliver us, O Parliament! Let us not be misunderstood, as detracting from the merits of Mr. Chadwick. His genius lies in the agitation of every kind of unnoticed physical filth, and dragging it, nolens volens, before the public, in order to get the nuisances abated. He is, moreover, a veritable Cerberus against every species of "Edic Ochiltree," seeking to lead an easy life without labour. He has the nose of noses for ferreting out any simulated distress, and can calculate to a nicety the exact ration justly due to a pauper, that he may neither deteriorate in body nor absorb too much of the public pabulum. He is the very genius of economy in soap and sewage, and could instruct even the "Scotch captain of a Liverpool brig" in sma' savings. Could he realise his beau ideal, the phrase, "How are you off for "would fall into desuetude. Such men are needed, soap and an invaluable public servant is Mr. Chadwick, as an exponent of existing evil, but there his faculties end. When he leaves the labourers part of clearing away the rubbish, and sets up as master-builder in hollow bricks and drain pipes, and universal stoves, and assumes to read lectures to engineers on the fallacies of their art, of which he, Mr. Chadwick, is the only true exponent, the matter becomes ludicrous, and perseverance in the endeavour to uphold technical failures in support of official dignity becomes a mischief. The shoemaker to his last, the scavenger to his besom, and Mr. Chadwick, as prosecutor-general of public nuisances, are good and fitting things, but non constat that the perception of a bad odour gives the chemical knowledge essential to neutralise it. I am, sir, yours, COSMOS. ORNAMENTATION OF METALS.* SIR,As a member of the Society of Arts, I cannot allow the subject of the Paper read by Mr. Aitken, "On Ancient and Modern Metal-working," wholly to pass without making a few remarks on one or two points he refers to. I send you a portion of two prints taken by the process mentioned, viz., by passing through rollers, between metal plates, perforated paper, lace, &c., in the year 1835, by Mr. John Smith, then engaged at the establishment of Messrs. De la Rue, of Bunhill-row. The circumstance is, doubtless, in there collection of those gentlemen, but, at the time, the invention was considered to be of no practical use. Relative to the subject of the ornamentation of metals by the same process, Mr. Aitken says, that ornamentation has been produced by rolls upon which the designs have been cut in relief, or the reverse, as those on copper calico cylindrical printing-rollers. This idea was likewise Mr. John Smith's, who engraved the same rolls, and gave them to Mr. R. F. Sturges, of Birmingham, in the year 1843, by whom they were used to a considerable extent. This was what may commonly be called embossing, the same as paper embossing, and could only be used on soft metals, such as Britannia metal, or others of a similar softness. If hard metals had been used, it would have damaged the engraved rolls in a very short period. By this process I would wish it to be understood, that if a person has, say half a dozen machines, or changes of rolls, as the case may be, he would have six patterns, which, for that description of ornamentation, would be quite adequate to meet the requirements of the market. By the process described by Mr. Aitken, the means used are perishable, and limited to certain descriptions of patterns, but by the engraved rolls any design, no matter how complicated or difficult of imitation, could be executed with great beauty and elaboration, which could not be the case with the other process. Enclosed is a piece of Britannia metal ornamented as described. I do not send it as a specimen of what can be done by the process, only as a sample of what has been done in soft metal. These causes led to the taking out of a patent by Mr. John Smith and myself, which will be found in the list of Patents Sealed, in the Journal of the Society for the week ending 16th September, 1853. This patent has for its object the production of any design, or ornament, on all hard metals, and more particularly on common tin plates, a commodity coming within the requirements of the many. You will see that the means used, as described in that specification, are two embossing rolls of suitable power, but the pattern roller, *Mr. W. H. Smith's letter, it will be observed, is dated the 20th of February last. Unfortunately the original letter mis. carried, which will account for its not having appeared be fore.-ED. +This, I am informed, was the principal object of Mr. R. F. Sturges' patent. Half a dozen of after being engraved, is subjected to the process of hardening-made so hard that I think I should not be out of place in saying it would last for ever. these rolls, of choice designs, would serve all the requirements of any market in that trade; and when tin is used, sheets of any size would be supplied to the workers of that material, and could be used by them in the ordinary manufacture of their trade. As these sheets, if there was a great demand for them, could be supplied at such a comparatively small cost, there can be no drawback to the adoption of the article, viz., a beautifully engraved appearance even to the edges of a common tin plate. This can be done to the size of (17X12) for the large sum of one half-penny, or even less. I will leave the merits of the two inventions to be decided by your more scientific readers. In the one case the means employed are imperishable, and any number of choice patterns can be obtained, and when once obtained, if the requirements of the market demand it, they may be multiplied without trouble by simply passing the sheets of any metal, soft or hard, through the rollers. This could not be done in any other way. It is very evident that the only expense is the original outlay, which is a matter that ought not to stand in the way of practicable results, when there is a chance of a return of the same by a public demand for the article. I send you a specimen of embossed tin; it is not only indented on the surface of the tin, but the iron is fairly worked up, and is capable, without deteriorating the appearance, of being worked up into any practicable shape, such as stamped, spun, and even hammered articles, and the pattern will not be obliterated. I am, yours, &c., 8, Upper Fountain-place, City-road, February 20th, 1854. W. H. SMITH. Proceedings of Institutions. BEDFORD.-The concluding lecture of the session was given on Wednesday last, by Mrs. C. L. Balfour, on "The Uses of Poetry and the Mission of the Poet." At its close, Mr. Coombs, hon. sec., (who, in the absence of the Mayor, was called on to preside,) presented the thanks of the members and of the audience to Mrs. Balfour, for her interesting and useful lecture, remarking that, as one of its results, the important uses of poetry and the high mission of the poet would be better understood and appreciated by those who had that evening had the pleasure of listening to the eloquent lecture. GATESHEAD.-The first annual meeting of the Wash ington Chemical Works Reading Institution and Library was held on Friday evening, the 5th inst. Mr. John Glover, vice-president, occupied the chair. From the report which was read by the secretary, Mr. R. Buddle, it appeared that the institution is in a healthy and prosperous condition. The abstract of accounts showed that after the payment of all liabilities, there remained a balance in the hands of the treasurer. The institution now number's 114 members. The volumes purchased during the last year amount to 160, a very considerable saving having been effected in their purchase, through the medium of the Society of Arts book arrangement. Although the formation of this institution originated with the workmen themselves, the Washington Chemical Company have very kindly seconded their efforts, having built and furnished two neat and commodious rooms for their accomodation. A donation of 101. has also been received from the President, Isaac Lowthian Bell, Esq. At present twelve newspapers and twenty periodicals are received into the news-rooms weekly, and these are of the most popular and instructive character. GLASGOW.-The annual distribution of prizes at the Mechanics' Institution took place on Wednesday se'nnight. The chair was occupied by Mr. James Gourlay, the senior magistrate, supported by others of the civic authorities, and by several of the vice-presidents and officers of the institution. Mr. George Good, the Secretary, read the annual report, which was of a highly favourable character. There had attended the chemistry class 119, the natural philosophy class 84, the music class 80, the mathematical class 82, the practical drawing class 163, and the botany class 129. The reading room of the Institute had fallen off in interest, and it had been discontinued, and the room appropriated to extend the drawing class. After a few observations from the Chairman, the following prizes were awarded: 1. The Birkbeck Testimonial Prize, value 21. 2s., to M. K. Armstrong, letter-press printer. 2. For the best account of the chemical lectures, 1. 1s., to J. Smith, engineer. 3. Mechanics' class, 1st prize, 17. 1s., to R. Anderson, draughtsman; 2nd prize, 15s., to J. M'Intyre, clerk; 4. Theory and practice of music, 1st prize, 15s., to D. Johnston; 2nd prize, 12s. 6d., to R. Rodger and M. K. Armstrong, equal. The committee had appropriated money for prizes in the Mathematical Class, but in consequence of the intimation being made too late, Professor Laing thought that a comparative examination could not then be instituted with justice to the class, and therefore he declined to offer prizes. 5. Mechanical Drawing Class, 1st prize, 12s. 6d., to J. A. Arneil, land surveyor, and D. Wilson, engineer, equal; 2nd prize, 10s. 6d., to J. Thompson, pattern maker; 3rd prize, 8s. 6d., to J. M'Lean; 4th prize., 6s., to J. Bacon. 6. For a model life boat, 21. to W. Lewis, pattern drawer. POOLE.-On Wednesday evening, the 3rd inst., H. D. Seymour, Esq., M.P., delivered a highly interesting lecture on behalf of the Mechanics' Institute, to a crowded audience, on the subject of his recent travels in the East, entitled "Southern India in 1853-4." This was a supplementary lecture to the Session, delivered by the honourable gentleman, in pursuance of a promise made by him some time previous to his visit to India, his abs ence from England having prevented his fulfilling his engagement during the Session.

PAPER FROM GORSE.-A correspondent of the Gardeners' Chronicle suggests that gorse might be used with advantage in manufacturing paper. He is in the habit of using large quanti. ties of crushed gorse as food for his horses. This is well mashed in water with a pestle till all soluble matter is separated About 50 per cent. of the green gorse appears to be water, and about 25 per cent. soluble matter in which its feeding properties mainly reside, and 25 per cent. woody fibre. In the process of mashing under water, some of this fibre was lost, but 17 per cent. of the whole weight of the fresh cut gorse was obtained. I find that I cut about 12 tons of gorse per statute acre annually on light and deep, but otherwise poor soil; so that a net yield of two tons of fibre per acre might be obtained. It would possibly be worth while so to arrange the process as to preserve and use the solution for moistening dry food for sheep and cattle. I do not know what value the paper makers would set on such fibre, but looking to the cost of waste cotton, I should think the value of 2 tous of it per acre ought to pay." ROYAL GEOGRAPHICAL SOCIETY.-The anniversary meeting of this society, for the election of officers, &c., will be held at Regent-street, on Monday, the 22nd inst., at one o'clock. During the ballot the royal medals "for the encouragement of geographical science and discovery," will be presented to RearAdmiral W. II. Smyth and Captain R. J. Le McClure, R.N., by the president, the Earl of Ellesmere, who will then deliver his annual address. The dinner will take place at the Freemasons' Tavern. Dated 27 April, 1854. 951. C. C.
