Part 23

DRY'DEN, John, English poet, was descended from an ancient family, his grandfather being Sir Erasmus Dryden of Canons Ashby, Northamptonshire. Born near Aldwinkle, Northamptonshire, in 1631, he was admitted a King's scholar at Westminster under the celebrated Dr. Busby, whence he went to Trinity College, Cambridge, being elected to a scholarship there. After leaving the university, he went to London, where he acted as secretary to his cousin Sir Gilbert Pickering, a favourite of Cromwell; and on the death of the Protector he wrote his _Heroic Stanzas_ on that event. At the Restoration, however, he hailed the return of Charles II in _Astraea Redux_, and from that time his devotion to the Stuarts knew no decay. In 1661 he produced his first play, _The Duke of Guise_; but the first that was performed was _The Wild Gallant_, which appeared in 1663 and was not a success. This was followed by _The Rival Ladies_, and _The Indian Queen_, a tragedy on Montezuma in heroic verse, written in collaboration with Sir Robert Howard, whose sister, Lady Elizabeth Howard, Dryden married in 1663. He followed up _The Indian Queen_ with _The Indian Emperor_, which at once raised Dryden to the highest pitch of public estimation, an elevation which he retained till his death. The great fire of London put a stop for some time to theatrical exhibitions. In the interval Dryden published the _Annus Mirabilis_, an historical account of the events of the year 1666, one of the most elaborate of his productions. In 1668 he also published his celebrated _Essay on Dramatic Poesy_--the first attempt to regulate dramatic writing. In 1668 _The Maiden Queen_, a tragi-comedy, was represented. This was followed in 1670 by _The Tempest_, an alteration from Shakespeare, in which he was assisted by Sir William Davenant. It was received with general applause, notwithstanding the very questionable taste and propriety of the added characters. Dryden was shortly afterwards appointed to the offices of Historiographer Royal and Poet Laureate, with a salary of L200 a year. He now became professionally a writer for the stage, and produced many pieces, some of which have been strongly censured for their licentiousness and want of good taste. The first of his political and poetical satires, _Absalom and Achitophel_ (Monmouth and Shaftesbury), was produced in 1681, and was followed by _The Medal_, a satire against sedition; and _Mac Flecknoe_, a satire on the poet Shadwell. In 1682 he published a poem called _Religio Laici_, wherein he maintained the doctrines of the Church of England. On the accession of James in 1685 Dryden became a Roman Catholic, a conversion the sincerity of which has been not unreasonably regarded with suspicion, considering the time at which it occurred. At court the new convert was received with open arms, a considerable addition was made to his pension, and he defended his new religion at the expense of the old one in a poem, _The Hind and the Panther_. Among his other services to the new king were a savage reply to an attack by Stillingfleet, and panegyrics on Charles and James under the title of _Britannia Rediviva_. At the Revolution Dryden was deprived of the offices of Poet Laureate and Historiographer, and of the certain income which these offices secured him. During the remaining ten years of his life he produced some of his best work, including his admirable translations from the classics. He published, in conjunction with Congreve, Creech, and others, a translation of Juvenal, and one of Persius entirely by himself. About a third part of Juvenal was translated by Dryden, who wrote an essay on satire which was prefixed to the whole. His poetic translation of Virgil appeared in 1697, and, soon after, the well-known lyric _Alexander's Feast_, and his _Fables_. He died 1st May, 1700, in the sixty-ninth year of his age, and was buried in Westminster Abbey. Dryden is unequalled as a satirist among English poets, and the best of his tragedies are unsurpassed by any since written. His poetry as a whole is more remarkable for vigour and energy than beauty, but he did much to improve English verse. He was also an admirable prose writer. Personally he was modest and kindly. The whole of his works, edited by Sir W. Scott, were published in 1818 (18 vols. 8vo); they were republished with additional notes, &c., by Professor Saintsbury (1882-93).--BIBLIOGRAPHY: R. Garnett, _Age of Dryden_; Sir A. W. Ward, _History of English Dramatic Literature_; _Cambridge History of English Literature_ (vol. viii).

DRYING-MACHINE, a machine consisting of any number of steam-heated cylinders up to thirty or even more, each about 22 inches in diameter, and used in bleachworks, dye-houses, and in cloth-finishing departments; used as a separate machine to dry fabrics which contain a certain amount of moisture left in at some previous operation, but often used in conjunction with a starching-mangle or similar apparatus. All the cylinders are in a horizontal plane, and usually in two rows, but such rows may be disposed either in horizontal or vertical frames. Floor-space is economized in the latter arrangement, and two or more groups of two rows per group may be provided for. Each cylinder is provided with some type of safety air-valve, which yields to allow air to enter in proportion as the steam is condensed in the cylinder, and so prevents the latter from collapsing. The condensed steam is withdrawn either by means of siphons or revolving scoops, so that the interior may be as dry as possible. The long length of cloth, either from the squeezing-rollers of the starch-mangle or from a loose or rolled state of cloth from some other machine, is conducted over guide-rollers, then under and over the two rows of steam-heated cylinders, and finally led from the last cylinder to the roller of a plaiting-down apparatus, or otherwise delivered. Both sides of the cloth thus come into direct contact with half the number of cylinders as it is drawn through the machine, and the dried cloth is ultimately delivered by the plaiting-down apparatus in folds ready for the subsequent operations.

DRYING-OILS, linseed and other oils, which are the bases of many paints and varnishes. When exposed to the air, they absorb oxygen, and are converted into a transparent, tough, dry mass or varnish.

DRY-POINT, a method of engraving generally regarded as part of etching, but more closely allied to line engraving. Instead of the copper being covered with etching ground and the lines bitten with acid, a pointed instrument is drawn across it, which incises a fine line with a more distinct burr on each side than that raised by a graver. This burr helps to give a characteristic quality to the line, but is rapidly worn away by printings. Dry-point may be used by itself, but is frequently combined with etching proper.

[Illustration: Dry-rot Fungus (_Merulius lacrymans_)]

DRY-ROT, a well-known disease affecting timber, occasioned by various species of Fungi, the mycelium of which penetrates the timber, destroying it. _Merulius lacrymans_, which is found chiefly in fir-wood, is the most common and most formidable dry-rot fungus in Britain; while _Polyp[)o]rus destructor_ is equally destructive in Germany. _P. vaporarius_ may also cause dry-rot. Damp, unventilated situations are most favourable to the development of dry-rot Fungi. Various methods have been proposed for the prevention of dry-rot; that most in favour is thoroughly saturating the wood with creosote, which makes the wood unfit for vegetation, but proper ventilation is the surest safeguard.

DUAL, in grammar, that number which is used, in some languages, to designate two things, whilst another number (the plural) exists to express many. The Greek, Sanskrit, and Gothic among ancient languages, and the Lithuanian and Arabic among modern, possess forms of the verb and noun in which two persons or things are denoted, called the _dual_ numbers.

DU'ALISM, the philosophical exposition of the nature of things by the hypothesis of two dissimilar primitive principles not derived from each other. Dualism in religion is chiefly confined to the adoption of a belief in two fundamental beings, a good and an evil one, as is done in some Oriental religions, especially that of Zoroaster. In metaphysics, dualism is the doctrine of those who maintain the existence of matter and form, or mind and matter, as distinct substances, in opposition to idealism, which maintains that we have no knowledge or assurance of the existence of anything but our own ideas or sensations. Dualism may correspond with realism in maintaining that our ideas of things are true transcripts of the originals, or rather of the qualities inherent in them, the spirit acting as a mirror and reflecting their true images; or it may hold that, although produced by outward objects, we have no assurance that in reality these at all correspond to our ideas of them, or even that they produce the same idea in two different minds. Among modern philosophers Professor W. McDougall and Bergson have defended the doctrine of dualism. See _Monism_.--BIBLIOGRAPHY: J. Ward, _The Realm of Ends_; W. James, _Essays in Radical Empiricism_; H. Bergson, _Matter and Memory_.

DUBAIL, Augustin Edmond, French general, born at Belfort 15th April, 1851. He served in the Franco-Prussian War, and was for many years colonel of a Zouave regiment in Algeria. Chief of the Staff of the French army in 1914, he commanded the First Army operating in Alsace-Lorraine, and successfully defended Nancy. Appointed Military Governor of Paris in 1915, he held this post until June, 1918.

DU BARRY, Marie Jeanne B['e]cu, Comtesse, mistress of Louis XV, was born at Vaucouleurs in 1743. She came young to Paris, and was presented to the king in 1769, who had her married for form's sake to the Comte du Barry. She exercised a powerful influence at court, and with some of her confidants completely ruled the king. Important offices and privileges were in her gift, and the courtiers abased themselves before her. After the death of Louis she was dismissed from court and sent to live in a convent near Meaux. She received a pension from Louis XVI. During the reign of terror she was arrested as a Royalist and executed, Nov., 1793.--Cf. N. Williams, _Madame du Barry_.

DUBIT'ZA, a fortified town of Bosnia, in Yugo-Slavia, on the right bank of the Unna, about 10 miles from its confluence with the Save. In the sixteenth and seventeenth centuries it was a frequent point of contention between Austria and Turkey. In 1878, with the rest of Bosnia, it passed under Austrian administration. Pop. 3260.--_Dubitza_, in Croatia, on the opposite bank of the Unna, has 6660 inhabitants.

DUB'LIN, the metropolis of Ireland, is situated in County Dublin, on the east coast of the island, at the mouth of the Liffey, the banks of which for more than 2 miles from the sea are lined with quays. The river, which divides the city into two unequal parts, is crossed by numerous bridges. In the old part of the city the streets are irregular, narrow, and filthy; in the more modern and aristocratic quarters there are fine streets, squares, and terraces, but with little pretension to architectural merit. The public buildings, however, are especially numerous and handsome. The main thoroughfare, east to west, is by the magnificent quays along the Liffey. The principal street at right angles to the river is Sackville Street, a splendid street 650 yards long and 40 yards wide, forming a thoroughfare which is continued across the river by O'Connell Bridge, a magnificent structure the same width as Sackville Street. The principal public secular buildings are the castle, the official residence of the viceroy; the Bank of Ireland, formerly the Irish Parliament House; Trinity College; the custom-house, destroyed in 1921; the King's Inns; the post office; rotunda; corn exchange; commercial buildings; the mansion house; and the city hall or corporation buildings. The most important literary and scientific institutions are Trinity College (Dublin University); the National University of Ireland; the Royal College of Science; the Catholic University; the College of Surgeons; the Royal Dublin Society; the Royal Hibernian Academy of Painting, Sculpture, and Architecture; the Royal Irish Academy for Promoting the Study of Science, Literature, and Antiquities; the Archaeological Society; and the Royal Zoological Society. Dublin contains two Protestant Episcopal cathedrals--St. Patrick's Cathedral, erected in 1190, and thoroughly restored between 1860 and 1865, through the munificence of Sir Benjamin Lee Guinness; and Christ's Church, built in 1038 and restored between 1870 and 1877, the restoration being carried out at the expense of Henry Roe. The Roman Catholic Cathedral is a very large edifice. The charitable institutions are numerous, and some of them possess splendid buildings. There are several extensive military and constabulary barracks in the city and vicinity. A little north-west of the city, up the Liffey, is the Phoenix Park, with an area of 1759 acres. In it are the Viceregal Lodge, the usual residence of the King's representative; the Chief Secretary's and Under-Secretary's official residences; the Royal Hibernian Military School; and the depot of the Royal Irish Constabulary; as also the gardens of the Royal Zoological Society. The manufactures carried on are of little note: poplins, for which Dublin has been long celebrated, are still in some request, and brewing and distilling are largely carried on. Since 1918 Dublin returns seven members to the House of Commons. The Sinn Fein members, however, elected in 1918, never attended the Imperial Parliament. Serious risings occurred in Dublin at Easter 1916, in 1919, and 1920, and there were also disorders in May 1921. Dublin is an ancient town, but its early history is obscure. It was held by the Danes for more than three centuries from 836. Pop. 399,000 (1919). The county, which is in the province of Leinster, on the east coast of the island, has an area of 218,873 acres, about a third of it under crops of various kinds, chiefly grass and clover. The surface on the whole is flat, but the ground rises at its southern boundary into a range of hills, the highest of which--Kippure--is 2473 feet above the sea. There is about 70 miles of sea-coast, the chief indentation being Dublin Bay. The principal stream is the Liffey, which intersects the county west to east. Important water communications are the Royal and the Grand Canals, both centering in Dublin, and uniting the Liffey with the Shannon. The manufactures are unimportant, but the fisheries are extensive. Since 1918 the county returns four members to the House of Commons. Pop. 172,394; Dublin (county borough), 304,802.--Cf. D. A. Chart, _The Story of Dublin_.

DUBLIN, UNIVERSITY OF, an institution founded in 1591, when a charter, or letters-patent, was granted by Queen Elizabeth for the incorporation of the "College of the Holy and Undivided Trinity", the University and Trinity College being practically the same. The corporation now consists of a provost, seven senior fellows, twenty-six junior fellows, and seventy foundation scholars. The Senate of the university consists of "the chancellor of the university, or in his absence, of the vice-chancellor, and such doctors or masters of the university as shall have and keep their names on the books of Trinity College". The Senate possesses the right of electing the chancellor of the university; it is also the body which grants degrees. The fellows are appointed for life, after an examination. The scholars are chosen from among the undergraduates, after an examination in mathematics and logic, or in Greek, Latin, and logic. The scholarships are tenable for five years, or till the degree of M.A. is attained. The course of general instruction extends over four years. The academical year is divided into three terms--Michaelmas, Hilary, and Trinity--and every student must keep at least two terms in each year in order to obtain a degree. The system of instruction is superintended by the fellows, both junior and senior, together with a large staff of professors in the various departments of science and literature. Eighteen of the junior fellows act as tutors, and every student must place himself under one of these on entering the college. The B.A. degree is given after examination in the usual subjects, and may be a pass or honours degree; the M.A., as at Oxford and Cambridge, is gained by the payment of a fee after a certain time has elapsed. There are also a law school, a medical school, and a school of engineering, and degrees are granted in these subjects, as well as in arts and divinity. The college possesses a library of about 285,000 printed volumes and 1700 manuscripts. It has also a botanic garden and museum. In 1613 James I granted to the university the right of returning two members to Parliament. One was taken away at the Union, but was restored by the Reform Bill of 1832. The number of students in 1920 was 1350.--Cf. _Dublin University Calendar_.

DUBNO, a town of the Ukraine, government of Volhynia. It was a place of some importance before the annexation of Western Poland by Russia. During the European War it was recaptured in the Russian advance in June, 1916. Pop. 14,000.

DUBOIS (d[.u]-bw[:a]), Guillaume, a French cardinal, was the son of an apothecary, born in 1656, died 1723. He became tutor to the Duke of Chartres, afterwards Duke of Orleans and Regent, and maintained his influence by pandering to the vices of his pupil. He became Privy Councillor and overseer of the duke's household, and Minister for Foreign Affairs under the regency. The archbishopric of Cambrai having become vacant, Dubois ventured to request it of the regent, although he was not even a priest. The regent was astonished at his boldness; but he obtained the post, having in one morning received all the clerical orders, and, a few days after, the archbishopric. By his consummate address he obtained a cardinal's hat, and in 1721 was appointed Prime Minister. Dubois was an avaricious, lying, licentious creature, yet clever and industrious, and able to make himself very agreeable where it suited his interest.

DUBOIS (d[.u]-bw[:a]), Paul, French sculptor, born 1829, died in 1905. He first studied law, but from 1856 to 1858 gave himself up to sculpture under Toussaint at Paris, and then went to Italy, where the sculptors of the early Renaissance, Donatello and Luca Della Robbia, had a decided influence upon him. Among his works are a _St. John_, a _Narcissus_, a _Madonna and Child_, _Eve Awakening to Life_, a figure of _Song_ for the opera-house at Paris, and numerous busts; but his greatest work is the monument of General Lamorici[`e]re in the Cathedral of Nantes, with figures of _Military Courage_, _Charity_, _Faith_, and _Meditation_, which rank among the best products of French plastic art. He is also distinguished as a painter of portraits. He was director of the ['E]cole des Beaux Arts from 1878 until his death, and received the grand cross of the Legion of Honour.

DU BOIS-REYMOND (d[.u] bw[:a]-r[=a]-m[=o][n.]), Emil, German physiologist, and an especial authority on animal electricity, born at Berlin 1818, died in 1896. He studied theology, geology, and afterwards anatomy and physiology, and became professor of physiology in the University of Berlin in 1858. His principal publication is _Researches in Animal Electricity_.

DUBOV'KA, a town of South Russia, government of Saratov, on the Volga; it has an extensive river trade in wool, iron, oil, and grain. Pop. 16,530.

DUBUQUE (du-b[=u]k'), a city of Iowa, United States, on the right bank of the Mississippi. It occupies an important commercial position as a railway centre and entrep[^o]t for the agricultural and mineral products of the northern half of Iowa, and the timber of Wisconsin, and also from the valuable lead-mines in its vicinity. Pop. 39,428.

DUCANGE (d[.u]-k[:a]nzh), Charles Dufresne, Sieur, a French historian and linguist, was born in 1610 near Amiens, died at Paris 1688. He studied in the Jesuits' College at Amiens, afterwards at Orleans and Paris. At this last place he became Parliamentary Advocate in 1631, and in 1645 Royal Treasurer at Amiens, from which place he was driven by a pestilence, in 1668, to Paris. Here he devoted himself entirely to literature, and published his great works, viz. his _Glossaries of the Greek and Latin peculiar to the Middle Ages and the Moderns_, his _Historia Byzantina_, the _Annals of Zonaras_, the _Numismatics of the Middle Ages_, and other important works.

DUCAS, Michael, Byzantine historian, flourished in the fifteenth century. His _Historia Byzantina_, which contains a reliable account of the siege and sack of Constantinople, was largely used by Gibbon.

DUC'AT (Lat. _duc[=a]tus_, a duchy), a coin formerly common in several European states. They were either of silver or gold: value of the former, 3s. to 4s., of the latter about 9s. 4d. They were named from being first coined in one of the Italian duchies.

DUCATOON', formerly a Dutch silver coin worth 3 gulden 3 stivers, or 5s. 3d. sterling. There were coins of the same name in Italy. In Tuscany its value was about 5s. 5d., in Savoy slightly more, and in Venice about 4s. 9d.

DU CHAILLU (d[.u]-sh[=a]-y[:u]), Paul Belloni, traveller, born in Paris 1835, died 1903. He spent his youth in the French settlement at the Gaboon, on the west coast of Africa, where his father was a merchant. In 1852 he went to the United States, of which he afterwards became a naturalized citizen. In 1855 he began his first journey through Western Africa, and stayed till 1859 alone among the different tribes, travelling on foot upwards of 8000 miles. He collected several gorillas, never before hunted, and rarely, if ever, before seen by any European. An account of this journey, _Explorations and Adventures in Equatorial Africa_, was published in 1861. A second expedition was made in 1863, an account of which, under the title _A Journey to Ashango Land_, appeared in 1867. _The Land of the Midnight Sun_, an account of a tour in Northern Europe (1881), had a considerable success. He published a number of books intended for boys, and based on his travels. One of his works is _The Viking Age_ (1889), on the ancestors of the English-speaking peoples.

DUCHESNE, or DU CHESNE (d[.u]-sh[=a]n), Andr['e], French historian, born in 1584, died in 1640. His most important works are his collection of French historians--_Historiae Francorum Scriptores_; _Historiae Normanorum Scriptores 838-1220_; _Histoire d'Angleterre, d'['E]cosse, et d'Irlande_; _Histoire des Papes_.

DUCIS (d[:u]-s[=e]s), Jean Francois, French dramatic writer, born at Versailles 1733, died 1816. Of his original works, the tragedy _Abufar_ was much admired; but he is now best known for his adaptations of Shakespeare to the Parisian stage.
