Of Summer's sky, in beauty bending o'er him- Sparkling in golden light, his own romantic bay, Tall spire, and glittering roof, and battlement, And many a scene forgot, the heart will hold Its memory of this; nor lives there one Whose infant breath was drawn, or boyhood days The heroine, so long forgotten, is at length reverted to, but she still appears to be no great favourite with her bard But where is Fanny? She has long been thrown The age of chivalry, you know, is gone; And although, as I once before have said, I love a pretty face to adoration, As a true Dandy of the modern schools. To treat the sex with too much courtesy. Of these enlighten'd days at evening crowd, Submission," which, in times of yore, the Knight To lounge in graceful attitudes-be star'd To dart upon the trays, as swiftly by The dexterous Simon bears them, and to take Is now to be the ton, &c. The poem concludes abruptly in the first line of what would be the CXXIII stanza if complete, leaving the reader much less interested for the fate of Fanny than amused by the playful wit and gentle pleasantry of Mr. Croaker. ART. XIII.-Account of a Patent taken out by Sir William Congreve, (England) for a new Steam Engine. DRAW RAW a right-angled parallelogram, and let AB be the top, CD the bottom, AC being the perpendicular line on the left hand of the designer. Then at a take aC to one-fourth of AC, and draw ab parallel to CD, and to one-third of the same; from b draw a curve approaching to BD, convex towards that line, and going off in an asymptote to it; let this line end in k, leaving a small distance between its termination and AB; next from AB, at the point g, whose distance from k must equal the distance of k from BD, (and both be comparatively very small) draw the line gh parallel to the asymptote and curve, and not passing beyond b. Lastly, within Aa hg draw a circle and radii, to which the sides Aa ab are tangent, and the curve gh nearly so. This figure will be a vertical section of the steam engine. AB DC is the boiler, abk is an iron division of the same, cutting off the part Aa bk, and having a performation in ab, in which a pipe is inserted, so that the water may flow freely from the upper into the lower division. gh is a similar division open at h, but the space gB is air-tight, the circle represents a water-wheel freely suspended on its axis within the boiler, and working a toothed wheel of smaller dimensions, whose centre is just above the line AB; the boiler is open, except the small part gB, and is supplied with water by a ballcock at A. With this arrangement, when the steam arises from the water in abCD, it will ascend up towards k, and pass down the open space kgbh, forcing the water before it, and thus communicating velocity to the water-wheel, being compressed in the steam chamber according to the height of the column of water thus forced down from k to h. Rushing, therefore, with the force thus acquired through the aperture h, it not only drives round the wheel by its energy and expansion as it ascends, but produces by the actual displacement of all the water or other fluid in the ascending buckets, a buoyant power on that side of the wheel equal to the actual weight of the quantity of water or other fluid thus displaced. The least moving power, therefore, of such a wheel, independent of the energy and expansion of the steam, may be reckoned as equal to the power which the same overshot-wheel เ would exert working in air by the fall of a column of water or other fluid, equal in quantity to the displacement of the steam in this case. The upper part of the boiler is always kept full by a common ball-cock, and the water in the upper compartment of the boiler communicating with that in the lower through the bent pipe ef, the lower boiler will thus also be regularly fed; and when the steam is up, the water in the lower boiler, or rather in the bottom of the steam chamber, will always stand on a level with the top of the aperture h, for then the opposite columns of pressure condensing, the steam between them will be in equilibrium; and up to this level will be the lower compartment of the boiler, while working, be always supplied through the pipe ef, though the steam cannot escape through it.' ART. XIV.-Miscellaneous Articles, &c. Comparative Table of the Extent, Population, Riches, Debts, Revenues, and Taxes, of Great Britain and France, for the year 1819. Croatian Literature.-The Austrian 'Observer' announces the publication of a work on Jurisprudence in the Croatian language entitled' Predananga,' &c. that is to say elements of Hungarian civil law, by E. Domin, professor of civil law in the Royal Academy of Agram. "This work written with perspicuity will increase the reputation of its learned author, and it is the more agreeable to us to announce it as it is the production of a country more famed abroad for the warlike spirit of its inhabitants than for the culture of the national language. Rev. Encyclopedique. Modern Greek Literature.-Mr. Koumas, professor and director of the 1,800,000,000 (Gazette de France.} new Greek college at Smyrna, has arrived at Vienna for the purpose of publishing several works. He has already issued the two first volumes of his Course of Philosophy, in modern Greek. He has also published the Elementary Chronology of Mr. Schoell, translated from the French, and the Abridgment of the history of Philosophy,' by Teneman, translated from the German. These two translations are also in modern Greek, and dedicated to Mr. Nicolaides, a Greek merchant, a native of Smyrna, but established at Odessa, and become illustrious for his generous patriotism. It is at the expense of this noble minded merchant these works are published for the instruction of youth. By his direction more than three hundred copies are dis-tributed gratis among those professors and students who distinguish themselves by their virtues, their talents, and their zeal in learning. ib. Among the learned men who do honor to modern Greece, Mr. Constantinos Oikonomos justly occupies a distinguished rank. In 1813 he published an excellent Treatise of Rhetoric.' He is professor of Greek and Latin literature, and has formed a number of excellent scholars. He is also preacher in the churches at Smyrna, and has acquired a great reputation by his attractive eloquence which draws to his sermons, besides the inhabitants of that opulent town, many consuls and other Europeans of distinction. In the number of his admirers is Mr. Anthimos, Archbishop of Smyrna, a native of Maxos, a respectable prelate and a zealous friend of letters. Mr. Oikonomos, without having ever quitted Greece is profoundly versed in general literature, in the Latin, Italian, French and German languages. The present patriarch of Constantinople of fered him one of the first chairs in the grand college at that capital, but he has been unwilling to leave the country of Homer, where he is detained by gratitude and friendship. He is the author of a work entitled [PAMMATIKON, &c. or a Course of Belles Letters, recently published, and dedicated to Mr. Alexander Mawros, one of the richest merchants of Greece, and at the same time one of the chief benefactors of that unhappy country. The greater part of the Greek merchants, particularly those of Odessa, where the duke de Richelieu, formerly govenor general of the Crimea, left so honourable a name, contribute also, each according to his abilities, to restore fallen Greece, and to revive among the Grecian youth a taste for liberal studies, and a love of letters, sciences, and the arts. There are three Journals published at Vienna, in modern Greek, the Commercial Telegraph, the Literary Telegraph and the Literary Mercury.' And one is just established at Stagira, called Calliope, by Mr. Athanasius, pro fessor of modern Greek in the Imperial Academy of that town. German Universities.-The disturbances connected with the Universities of Germany, appear to have had considerable effect upon the number of Students belonging to them. Formerly Gottingen reckoned more than a thousand students; but from a late estimate it appeared to have only 770. Halle has 500; Breslau has 366; Heidelberg has 363; Gressen has 241; Marburgh has 197; Kiel has 107; Rostock has 160; Greifswald has 55; Landshut has 640; Tubingen has 698; Berlin has 942; Leipsic has 911; Jena has 634; Vienna has 957; and Prague has 880. The whole number is 8,421 in the sixteen principal Universities of Germany. Search of the Tiber and Pompeia.The search of the Tiber has commenc ed at Rome, but it is said with but little success. The excavations at Pompeia are carried on very successfully, and several new edifices are said to have been discovered in the street which leads to the temple of Isis, to that of Hercules, and to the Theatre. Some surgical instruments, of good workmanship, are described to have been found. Prize Questions.-The royal academy of Inscriptions and Belles Letters at Paris, have proposed the following prize subject for the year 1821:-' To compare the monuments which remain of the ancient empire of Persia and Chaldea, either edifices, bassorelievos, statues, or inscriptions, amulets, coins, engraved stones, cylinders, &c., with the religious doctrines and allegories contained in the Zend Avesta, and with the indications and data which have been preserved to us by Hebrew, Greek, Latin, and Oriental writers, on the opinions and customs of the Persians and Chaldeans, and to illustrate and explain them as much as possible by each other.' The prize is a gold medal of 1,500 francs value. The essays are to be written in Latin or French, and sent in before the 1st of April, 1821. The prize will be adjudged in July following. The Society of Sciences, Arts and Belles Letters at Dijon has proposed the following questions as the subject for the prize to be awarded in 1820:What may be the most effectual means of extirpating from the hearts of Frenchmen that moral disease, a remnant of the barbarism of the middle ages; that false point of honor which leads them to shed blood in duels, in defiance of the precepts of religion and the laws of the state?' Prizes proposed by the Royal Academy of Copenhagen.-Mathematics.Num inclinatio et vis acus magnetica iisdem, quibus declinatio diurnis variationibus sunt subjecta?

Geology.-Quæ Saxa ad montes ordinis secundi, seu transitorios, pertinentia in Norwegia reperiuntur? This prize proposed by his excellency S. G. Moltke, is of the value of 550 rubles. The memoirs are to be written in Latin, French, English, German, Swedish, or Danish, and should be directed to M. H. C. Orsted, secretary to the academy, by December, 1819. Scientific Questions.-The royal academy of sciences and Belles Letters of Brussels have proposed for competition, during the year 1820, the following questions in the department of science. 1. Suppose a plate of a given figure, attached to a surface either by means of screws of a known number, position, and force, or by means of some intermediate matter capable of uniting the one to the other solidly, and the specific tenacity of which is also known; if to a point in the circumference of this plate, an arm be affixed, which acts in the same plane with the surface, it is required to know what resistance this plate will be capable of making against a force applied to this arm as a lever, considering the material, as well of the plate as of the arm and surface, as a 5. What is the true chemical composition of sulphurets, as well oxidized as hydrogenized, made according to the different processes, and what are their uses in the arts? The answers are to be supported, as far as possible, by new facts and experiments easy of repetition. COMMUNICATED. Obituary.-In the neighbourhood of Georgetown S. C. departed this life on the eleventh of August, Joseph Pyatt, Esq. in the thirtieth year of his age. Death in all his triumphs, never exulted over an event, more melancholy in its circumstances and better calculated to prostrate human pride. But a little while, and the deceased was seen in the ruddy bloom of manhood, mingling as eagerly as any of us, in the busy pursuits of life, full of present joy, flushed with future hope. Where is he now? and where are his air-built visions?—The morning had already passed away, without a cloud, and the peerless brightness with which the noon commenced seemed to promise a long summer day of ceaseless sunshine and unbroken serenity. Alas! how shadowy and delusive is every thing of this world. At the very moment when the sky was clear |
