Chapter V: Front Matter (5)

DUFRESNY, CHARLES, SIEUR DE LA RIVIERE (1648-1724), French dramatist, was born in Paris in 1648. The allegation that his grandfather was an illegitimate son of Henry IV. procured him the liberal patronage of Louis XIV., who gave him the post of _valet de chambre_, and affixed his name to many lucrative privileges. Dufresny's expensive habits neutralized all efforts to enrich him, and as if to furnish a piquant commentary on the proverb that poverty makes us acquainted with strange bedfellows, he married, as his second wife, a washerwoman, in discharge of her bill--a whimsicality which supplied Le Sage with an episode in the _Diable boiteux_, and was made the subject of a comedy by J.M. Deschamps (_Charles Riviere Dufresny, ou le mariage impromptu_). He died in Paris on the 6th of October 1724. His plays, destitute for the most part of all higher qualities, abound in sprightly wit and pithy sayings. In the six volumes of his _Theatre_ (Paris, 1731), some of the best are _L'Esprit de contradiction_ (1700), _Le Double Veuvage_ (1701), _La Joueuse_ (1709), _La Coquette de village_ (1715), _La Reconciliation normande_ (1719) and _Le Mariage fait et rompu_ (1721). A volume of _Poesies diverses_, two volumes of _Nouvelles historiques_ (1692), and _Les Amusements serieux et comiques d'un Siamois_ (1705), a work to which Montesquieu was indebted for the idea of his _Lettres persanes_, complete the list of Dufresny's writings. The best edition of his works is that of 1747 (4 vols.). His _Theatre_ was edited (1882) by Georges d'Heylli.

DUGAZON [JEAN HENRI GOURGAUD] (1746-1809), French actor, was born in Marseilles on the 15th of November 1746, the son of the director of military hospitals there. He began his career in the provinces, making his debut in 1770 at the Comedie Francaise, where he aspired to leading comedy roles. He pleased the public at once and was made _societaire_ in 1772. Dugazon was an ardent revolutionist, helped the schism which divided the company, and went with Talma and the others to what became the Theatre de la Republique. After the closing of this theatre, and the dissolution of the Comedie Francaise, he took refuge at the Theatre Feydeau until (1799) he returned to the restored Comedie. He retired in 1807, and died insane at Sandillon in 1809. Dugazon wrote three mediocre comedies of a political character, performed at the Theatre de la Republique. He married, in 1776, Louis Rose Lefevre, but was soon divorced and then married again. The first Madame Dugazon (1755-1821), the daughter of a Berlin dancing master, was a charming actress. Her first appearance on the stage was made at the age of twelve as a dancer. It was as an actress "with songs" that she made her debut at the Comedie Italienne in 1774 in Gretry's _Sylvain_. She was at once admitted _pensionnaire_ and in 1776 _societaire_. Madame Dugazon delighted all Paris, and nightly crowded the Comedie Italienne for more than twenty years. The two kinds of parts with which she was especially identified--young mothers and women past their first youth--are still called "_dugazons_" and "_meres dugazons_." Examples of the first are Jenny in _La Dame blanche_ and Berthe de Simiane in _Les Mousquetaires de la reine_; of the second, Marguerite in _Le Pre aux clercs_ and the queen in _La Part du diable_.

Dugazon's sister, MARIE ROSE GOURGAUD (1743-1804), was an actress who first played at Stuttgart, where she married Angelo, brother of Gaetano Vestris, the dancer. Under the protection of the dukes of Choiseul and Duras, she was commanded to make her debut at the Comedie Francaise in 1768, where she created important parts in a number of tragedies.

DUGDALE, SIR WILLIAM (1605-1686), English antiquary, was born at Shustoke, near Coleshill, in Warwickshire, on the 12th of September 1605, the son of a country gentleman of an old Lancashire stock; he was educated at Coventry. To please his father, who was old and infirm, he married at seventeen. He lived with his wife's family until his father's death in 1624, when he went to live at Fillongley, near Shustoke, an estate formerly purchased for him by his father. In 1625 he purchased the manor of Blythe, Shustoke, and removed thither in 1626. He had early shown an inclination for antiquarian studies, and in 1635, meeting Sir Symon Archer (1581-1662), himself a learned antiquary, who was then employed in collecting materials for a history of Warwickshire, he accompanied him to London. There he made the acquaintance of Sir Christopher (afterwards Lord) Hatton, comptroller of the household, and Thomas, earl of Arundel, then earl marshal of England. In 1638 Dugdale was created a pursuivant of arms extraordinary by the name of Blanch Lyon, and in 1639 rouge croix pursuivant in ordinary. He now had a lodging in the Heralds' Office, and spent much of his time in London examining the records in the Tower and the Cottonian and other collections of MSS. In 1641 Sir Christopher Hatton, foreseeing the war and dreading the ruin and spoliation of the Church, commissioned him to make exact drafts of all the monuments in Westminster Abbey and the principal churches in England, including Peterborough, Ely, Norwich, Lincoln. Newark, Beverley, Southwell, Kingston-upon-Hull, York, Selby, Chester, Lichfield, Tamworth and Warwick. In June 1642 he was summoned to attend the king at York. When war broke out Charles deputed him to summon to surrender the castles of Banbury and Warwick, and other strongholds which were being rapidly filled with ammunition and rebels. He went with Charles to Oxford, remaining there till its surrender in 1646. He witnessed the battle of Edgehill, where he made afterwards an exact survey of the field, noting how the armies were drawn up, and where and in what direction the various movements took place, and marking the graves of the slain. In November 1642 he was admitted M.A. of the university, and in 1644 the king created him Chester herald. During his leisure at Oxford he collected material at the Bodleian and college libraries for his books. In 1646 Dugdale returned to London and compounded for his estates, which had been sequestrated, by a payment of L168. After a visit to France in 1648 he continued his antiquarian researches in London, collaborating with Richard Dodsworth in his _Monasticon Anglicanum_, which was published successively in single volumes in 1655, 1664 and 1673. At the Restoration he obtained the office of Norroy king-at-arms, and in 1677 was created garter principal king-at-arms, and was knighted. He died "in his chair" at Blythe Hall on the 10th of February 1686.

Dugdale's most important works are _Antiquities of Warwickshire_
(1656); _Monasticon Anglicanum_ (1655-1673); _History of St Paul's
Cathedral_ (1658); and _Baronage of England_ (1675-1676). His _Life_,
written by himself up to 1678, with his diary and correspondence, and
an index to his manuscript collections, was edited by William Hamper,
and published in 1827.

DUGONG, one of the two existing generic representatives of the Sirenia, or herbivorous aquatic mammals. Dugongs are distinguished from their cousins the manatis by the presence in the upper jaw of the male of a pair of large tusks, which in the female are arrested in their growth, and remain concealed. There are never more than five molar teeth on each side of either jaw, or twenty in all, and these are flat on the grinding surface. The flippers are unprovided with nails, and the tail is broad, and differs from that of the manati in being crescent-shaped instead of rounded. The bones are hard and firm, and take a polish equal to that of ivory. Dugongs frequent the shallow waters of the tropical seas, extending from the east coast of Africa north of the mouth of the Zambezi, along the shores of the Indian, Malayan and Australian seas, where they may be seen basking on the surface of the water, or browsing on submarine pastures of seaweed, for which the thick obtuse lips and truncated snout pre-eminently fit them. They are gregarious, feeding in large numbers in localities where they are not often disturbed. The female produces a single young one at a birth, and is remarkable for the great affection it shows for its offspring, so that when the young dugong is caught there is no difficulty in capturing the mother. Three species--the Indian dugong (_Halicore dugong_), the Red Sea dugong (_H. tabernaculi_) and the Australian dugong (_H. australis_)--are commonly recognized. The first is abundant along the shores of the Indian Ocean, and is captured in large numbers by the Malays, who esteem its flesh a great delicacy; the lean portions, especially of young specimens, are regarded by Europeans as excellent eating. It is generally taken by spearing, the main object of the hunter being to raise the tail out of the water, when the animal becomes perfectly powerless. It seldom attains a length of more than 8 or 10 ft. The Australian dugong is a larger species, attaining sometimes a length of 15 ft.; it occurs along the Australian coast from Moreton Bay to Cape York, and is highly valued by the natives, who hunt it with spears, and gorge themselves with its flesh, when they are fortunate enough to secure a carcase. Of late years the oil obtained from the blubber of this species has been largely used in Australia as a substitute for cod-liver oil. It does not contain iodine, but is said to possess all the therapeutic qualities of cod-liver oil without its nauseous taste. A full-grown dugong yields from 10 to 12 gallons of oil, and this forms in cold weather a thick mass, and requires to be melted before a fire previous to being used. The flesh of the Australian dugong is easy of digestion, the muscular fibre when fresh resembling beef, and when salted having the flavour of bacon. In the earliest Australian dugong-fishery natives were employed to harpoon these animals, which soon, however, became too wary to allow themselves to be approached near enough for this purpose, and the harpoon was abandoned for the net. The latter is spread at night, and in its meshes dugongs are caught in considerable numbers. (R. L.*)

DUGUAY-TROUIN, RENE (1673-1736), French sea captain, belonged to a well-known family of merchants and sea captains of St Malo. He was born at St Malo on the 10th of June 1673. He was originally intended for the church, and studied with that view at Rennes and Caen; but on the breaking out of the war with England and Holland in 1689 he went to sea in a privateer owned by his family. During the first three months his courage was tried by a violent tempest, an imminent shipwreck, the boarding of an English ship, and the threatened destruction of his own vessel by fire. The following year, as a volunteer in a vessel of 28 guns, he was present in a bloody combat with an English fleet of five merchant vessels. The courage he then showed was so remarkable that in 1691, at the age of eighteen, his family gave him a corsair of 14 guns; and having been thrown by a tempest on the coast of Ireland, he burned two English ships in the river Limerick. In 1694 his vessel of 40 guns was captured by the English, and, being taken prisoner, he was confined in the castle of Plymouth. He escaped, according to his own account, by the help of a pretty shopwoman and her lover, a French refugee in the English service. He then obtained command of a vessel of 48 guns, and made a capture of English vessels on the Irish coast. In 1696 he made a brilliant capture of Dutch vessels, and the king hearing an account of the affair gave him a commission as _capitaine de fregate_ (commander) in the royal navy. In 1704-1705 he desolated the coasts of England. In 1706 he was raised to the rank of captain of a vessel of the line. In 1707 he was made chevalier of the order of St Louis, and captured off the Lizard the greater part of an English convoy of troops and munitions bound for Portugal. His most glorious action was the capture in 1711 of Rio Janeiro, on which he imposed a heavy contribution. In 1715 he was made _chef d'escadre_, the rank which in the French navy answered to the English commodore, and in 1728 commander of the order of St Louis and _lieutenant general des armees navales_. In 1731 he commanded a squadron for the protection of French commerce in the Levant. He died on the 27th of September 1736.

DU GUESCLIN, BERTRAND (c. 1320-1380), constable of France, the most famous French warrior of his age, was born of an ancient but undistinguished family at the castle of La Motte-Broons (Dinan). The date of his birth is doubtful, the authorities varying between 1311 and 1324. The name is spelt in various ways in contemporary records, e.g. Claquin, Klesquin, Guescquin, Glayaquin, &c. The familiar form is found on his monument at St Denis, and in some legal documents of the time. In his boyhood Bertrand was a dull learner, spending his time in open-air sports and exercises, and could never read or write. He was remarkable for ugliness, and was an object of aversion to his parents. He first made himself a name as a soldier at the tournament held at Rennes in 1338 to celebrate the marriage of Charles of Blois with Jeanne de Penthievre, at which he unseated the most famous competitors. In the war which followed between Charles of Blois and John de Montfort, for the possession of the duchy of Brittany, he served his apprenticeship as a soldier (1341). As he was not a great baron with a body of vassals at his command, he put himself at the head of a band of adventurers, and fought on the side of Charles and of France. He distinguished himself by a brilliant action at the siege of Vannes in 1342; and after that he disappears from history for some years.

In 1354, having shortly before been made a knight, he was sent into England with the lords of Brittany to treat for the ransom of Charles of Blois, who had been defeated and captured by the English in 1347. When Rennes and Dinan were attacked by the duke of Lancaster in 1356, Du Guesclin fought continuously against the English, and at this time he engaged in a celebrated duel with Sir Thomas Canterbury. He finally forced his way with provisions and reinforcements into Rennes, which he successfully defended till June 1357, when the siege was raised in pursuance of the truce of Bordeaux. For this service he was rewarded with the lordship of Pontorson. Shortly afterwards he passed into the service of France, and greatly distinguished himself at the siege of Melun (1359), being, however, taken prisoner a little later by Sir Robert Knollys. In 1360, 1361 and 1362 he was continually in the field, being again made prisoner in 1360. In 1364 he married, but was soon again in the field, this time against the king of Navarre. In May 1364 he won an important victory over the Navarrese at Cocherel, and took the famous Captal de Buch prisoner. He had previously been made lord of La Roche-Tesson (1361) and chamberlain (1364); he was now made count of Longueville and lieutenant of Normandy. Shortly afterwards, in aiding Charles of Blois, Du Guesclin was taken prisoner by Sir John Chandos at the battle of Auray, in which Charles was killed. The close of the general war, however, had released great numbers of mercenaries (the great companies) from control, and, as they began to play the part of brigands in France, it was necessary to get rid of them. Du Guesclin was ransomed for 100,000 crowns, and was charged to lead them out of France. He marched with them into Spain, supported Henry of Trastamara against Pedro the Cruel, set the former upon the throne of Castile (1366), and was made constable of Castile and count of Trastamara. In the following year he was defeated and captured by the Black Prince, ally of Pedro, at Navarette, but was soon released for a heavy ransom. Once more he fought for Henry, won the battle of Montiel (1369), reinstated him on the throne, and was created duke of Molinas.

In May 1370, at the command of Charles V., who named him constable of France, he returned to France. War had just been declared against England, and Du Guesclin was called to take part in it. For nearly ten years he was engaged in fighting against the English in the south and the west of France, recovering from them the provinces of Poitou, Guienne and Auvergne, and thus powerfully contributing to the establishment of a united France. In 1373, when the duke of Brittany sought English aid against a threatened invasion by Charles V., Du Guesclin was sent at the head of a powerful army to seize the duchy, which he did; and two years later he frustrated the attempt of the duke with an English army to recover it. Finding in 1379 that the king entertained suspicions of his fidelity to him, he resolved to give up his constable's sword and retire to Spain. His resolution was at first proof against remonstrance; but ultimately he received back the sword, and continued in the service of France. In 1380 he was sent into Languedoc to suppress disturbances and brigandage, provoked by the harsh government of the duke of Anjou. His first act was to lay siege to the fortress of Chateauneuf-Randon, but on the eve of its surrender the constable died on the 13th of July 1380. His remains were interred, by order of the king, in the church of St Denis. Du Guesclin lost his first wife in 1371, and married a second in 1373, but he left no legitimate children.

translated into French (1866) by order of Marshal Count Randon,
minister of war; also S. Luce, _Histoire de B. du Guesclin_ (Paris,
1876).

DUHAMEL, JEAN BAPTISTE (1624-1706), French physicist, was born in 1624 at Vire in Normandy. He studied at Caen and Paris; wrote at eighteen a tract on the _Spherics_ of Theodosius of Tripolis; then became an Oratorian priest, and fulfilled with great devotion for ten years (1653-1663) the duties of _cure_ at Neuilly-sur-Marne. He was appointed in 1656 almoner to the king, and in 1666 perpetual secretary to the newly founded Academy of Sciences. He died on the 6th of August 1706. He published among other works: _Astronomia physica_ (1660) and _De meteoris et fossilibus_ (1660), both in dialogue form; _De consensu veteris et novae philosophiae_ (1663); _De corporum affectionibus_ (1672); _De mente humana_ (1673); _Regiae scientiarum Academiae historia_, 1666-1696 (1698), new edition brought down to 1700 (1701); _Institutiones biblicae_ (1698); followed by annotated editions of the Psalms (1701), of the Book of Wisdom, &c. (1703), and of the entire Bible in 1705.

DUHAMEL DU MONCEAU, HENRI LOUIS (1700-1782), French botanist and engineer, son of Alexandre Duhamel, lord of Denainvilliers, was born at Paris in 1700. Having been requested by the Academy of Sciences to investigate a disease which was destroying the saffron plant in Gatinais, he discovered the cause in a parasitical fungus which attached itself to the roots, and this achievement gained him admission to the Academy in 1728. From then until his death he busied himself chiefly with making experiments in vegetable physiology. Having learned from Sir Hans Sloane that madder possesses the property of giving colour to the bones, he fed animals successively on food mixed and unmixed with madder; and he found that their bones in general exhibited concentric strata of red and white, whilst the softer parts showed in the meantime signs of having been progressively extended. From a number of experiments he was led to believe himself able to explain the growth of bones, and to demonstrate a parallel between the manner of their growth and that of trees. Along with the naturalist Buffon, he made numerous experiments on the growth and strength of wood, and experimented also on the growth of the mistletoe, on layer planting, on smut in corn, &c. He was probably the first, in 1736, to distinguish clearly between the alkalis, potash and soda. From the year 1740 he made meteorological observations, and kept records of the influence of the weather on agricultural production. For many years he was inspector-general of marine, and applied his scientific acquirements to the improvement of naval construction. He died at Paris on the 13th of August 1782.

His works are nearly ninety in number, and include many technical
handbooks. The principal are:--_Traite des arbres et arbustes qui se
cultivent en France en pleine terre_; _Elements de l'architecture
navale_; _Traite general des peches maritimes et fluviatiles_;
_Elements d'agriculture_; _La Physique des arbres_; _Des Semis et
plantations des arbres et de leur culture_; _De l'exploitation des
bois_; _Traite des arbres fruitiers_.

DUHRING, EUGEN KARL (1833-1901), German philosopher and political economist, was born on the 12th of January 1833 at Berlin. After a legal education he practised at Berlin as a lawyer till 1859. A weakness of the eyes, ending in total blindness, occasioned his taking up the studies with which his name is now connected. In 1864 he became _docent_ of the university of Berlin, but, in consequence of a quarrel with the professoriate, was deprived of his licence to teach in 1874. Among his works are _Kapital und Arbeit_ (1865); _Der Wert des Lebens_ (1865); _Naturliche Dialektik_ (1865); _Kritische Geschichte der Philosophie_ (1869); _Kritische Geschichte der allgemeinen Principien der Mechanik_ (1872)--one of his most successful works; _Kursus der National- und Sozialokonomie_ (1873); _Kursus der Philosophie_ (1875), entitled in a later edition _Wirklichkeitsphilosophie; Logik und Wissenschaftstheorie_ (1878); _Der Ersatz der Religion durch Vollkommeneres_ (1883). He published his autobiography in 1882 under the title _Sache, Leben und Feinde_; the mention of "Feinde" (enemies) is characteristic. Duhring's philosophy claims to be emphatically the philosophy of reality. He is passionate in his denunciation of everything which, like mysticism, tries to veil reality. He is almost Lucretian in his anger against religion which would withdraw the secret of the universe from our direct gaze. His "substitute for religion" is a doctrine in many points akin to Comte and Feuerbach, the former of whom he resembles in his sentimentalism. Duhring's opinions changed considerably after his first appearance as a writer. His earlier work, _Naturliche Dialektik_, in form and matter not the worst of his writings, is entirely in the spirit of the Critical Philosophy. Later, in his movement towards Positivism, he strongly repudiates Kant's separation of phenomenon from noumenon, and affirms that our intellect is capable of grasping the whole reality. This adequacy of thought to things is due to the fact that the universe contains but one reality, i.e. matter. It is to matter that we must look for the explanation both of conscious and of physical states. But matter is not, in his system, to be understood with the common meaning, but with a deeper sense as the substratum of all conscious and physical existence; and thus the laws of being are identified with the laws of thought. In this materialistic or quasi-materialistic system Duhring finds room for teleology; the end of Nature, he holds, is the production of a race of conscious beings. From his belief in teleology he is not deterred by the enigma of pain; he is a determined optimist. Pain exists to throw pleasure into conscious relief. In ethics Duhring follows Comte in making sympathy the foundation of morality. In political philosophy he teaches an ethical communism, and attacks the Darwinian principle of struggle for existence. In economics he is best known by his vindication of the American writer H.C. Carey, who attracts him both by his theory of value, which suggests an ultimate harmony of the interests of capitalist and labourer, and also by his doctrine of "national" political economy, which advocates protection on the ground that the morals and culture of a people are promoted by having its whole system of industry complete within its own borders. His patriotism is fervent, but narrow and exclusive. He idolized Frederick the Great, and denounced Jews, Greeks, and the cosmopolitan Goethe. Duhring's clear, incisive writing is disfigured by arrogance and ill-temper, failings which may be extenuated on the ground of his physical affliction. He died in 1901.

DUIGENAN, PATRICK (1735-1816), Irish lawyer and politician, was the son of a Leitrim Roman Catholic farmer named O'Duibhgeannain. Through the tuition of the local Protestant clergyman, who was interested in the boy, he got a scholarship in 1756 at Trinity College, Dublin, and subsequently became a fellow. He was called to the Irish bar in 1767 and obtained a rich practice. He is remembered, however, mainly as a politician, on account of his opposition to Grattan, his support of the Union, and his violent antagonism to Catholic emancipation. He was elected member for Armagh in the first united parliament, and was a well-known character at Westminster till he died on the 11th of April 1816.

DUIKER (diver), or DUIKERBOK, the Dutch name of a small S. African antelope, scientifically known as _Cephalophus grimmi_; the popular name alluding to its habit of diving into and threading its way through thick bush. Scientifically the name is extended to include all the members of the African genus _Cephalophus_, which, together with the Indian chousingha, or four-horned antelope (_Tetraceros_), constitutes the subfamily _Cephalophinae_. Duikers are animals of small or medium size, usually frequenting thick forest. The horns, usually present in both sexes, are small and straight, situated far back on the forehead; and between them rises the crest-like tuft of hair from which the genus takes its scientific name. The common or true duiker (_C. grimmi_) is found in bush-country from the Cape to the Zambezi and Nyasaland, and ranges northward on the west coast to Angola. The banded duiker (_C. doriae_) from West Africa is golden brown with black transverse bands on the back and loins. _C. sylvicultor_, of West Africa, is the largest species, and approaches a donkey in size. (See ANTELOPE.) (R. L.*)

DUILIUS (or DUELLIUS), GAIUS, Roman general during the first Carthaginian War and commander in the first Roman naval victory. In 260 B.C., when consul in command of the land forces in Sicily, he was appointed to supersede his colleague Cn. Cornelius Scipio Asina, commander of the fleet, who had been captured in the harbour of Lipara. Recognizing that the only chance of victory lay in fighting under conditions as similar as possible to those of a land engagement, he invented a system of grappling irons (_corvi_) and boarding bridges, and gained a brilliant victory over the Carthaginian fleet off Mylae on the north coast of Sicily. He was accorded a triumph and the distinction of being accompanied, when walking in the streets during the evening, by a torchbearer and a flute-player. A memorial column (_columna rostrata_), adorned with the beaks of the captured ships, was set up in honour of his victory. The inscription upon it (see LATIN LANGUAGE, section 3, "The Language as Recorded") has been preserved in a restored form in pseudo-archaic language, ascribed to the reign of Claudius.

DUISBURG, a town of Germany in the kingdom of Prussia, 15 m. by rail N. from Dusseldorf, between the Rhine and the Ruhr, with which rivers it communicates by a canal. It is an important railway centre. Pop. (1885) 47,519; (1900) 92,729; (1905), including many outlying townships then recently incorporated, 191,551. It has six Roman Catholic and six Protestant churches, among the latter the fine Gothic Salvatorkirche, of the 15th century. It is well furnished with schools, which include a school of machinery. Of modern erections, the concert hall, the law courts and a memorial fountain to the cartographer Gerhard Kremer (Mercator) are worthy of mention. There are important foundries, rolling mills for copper, steel and brass plates, chemical works, saw-milling, shipbuilding, tobacco, cotton, sugar, soap and other manufactures.

Duisburg was known to the Romans as _Castrum Deutonis_, and mentioned under the Frankish kings as _Dispargum_. In the 12th century it attained the rank of an imperial free town, but on being mortgaged in 1290 to Cleves it lost its privileges. At the beginning of the 17th century it was transferred to Brandenburg, and during the Thirty Years' War was alternately occupied by the Spaniards and the Dutch. In 1655 the elector Frederick William of Brandenburg founded here a Protestant university, which flourished until 1802.

DUK-DUK, a secret society of New Britain or New Pomerania, Bismarck Archipelago, in the South Pacific. The society has religious and political as well as social objects. It represents a rough sort of law and order through its presiding spirit Duk-Duk, a mysterious figure dressed in leaves to its waist, with a helmet like a gigantic candle-extinguisher made of network. Upon this figure women and children are forbidden to look. Women, who are entitled in New Britain to their own earnings and work harder than men, are the special victims of Duk-Duk, who levies blackmail upon them if they are about during its visits. These are generally timed to coincide with the hours at which the women are out in the fields and therefore cannot help seeing the figure. Justice is executed, fines extorted, taboos, feasts, taxes and all tribal matters are arranged by the Duk-Duk members, who wear hideous masks or chalk their faces. In carrying out punishments they are allowed to burn houses and even kill people. Only males can belong to Duk-Duk, the entrance fees of which vary from 50 to 100 fathoms of _dewarra_ (small cowrie shells strung on strips of cane). The society has its secret signs and ritual, and festivals at which the presence of a stranger would mean his death. Duk-Duk only appears with the full moon. The society is now much discredited and is fast dying out.

See "Duk-Duk and other Customs or Forms of Expression of the
Melanesian's Intellectual Life," by Graf von Pfeil (_Journ. of
Anthrop. Instit._ vol. 27, p. 181).

DUKE (corresponding to Fr. _duc_, Ital. _duca_, Ger. _Herzog_), the title of one of the highest orders of the European nobility, and of some minor sovereign princes. The word "duke," which is derived from the Lat. _dux_, a leader, or general, through the Fr. _duc_ (O. Fr. _dusc_, _ducs_, _dus_), originally signified a leader, and more especially a military chief, and in this latter sense was the equivalent of the A.S. _heretoga_ (_here_, an army, and _teon_, from _togen_, to draw; Ger. _ziehen_, _zog_; Goth, _tiuhan_; Lat. _ducere_) and the old Ger. _herizog_. In this general sense the word survived in English literature until the 17th century, but is now obsolete.

The origin of modern dukes is twofold. The _dux_ first appears in the Roman empire under the emperor Hadrian, and by the time of the Gordians has already a recognized place in the official hierarchy. He was the general appointed to the command of a particular expedition and his functions were purely military. In the 4th century, after the separation of the civil and military administrations, there was a duke in command of the troops quartered in each of the frontier provinces of the empire, e.g. the _dux Britanniarum_. The number of dukes continually increased, and in the 6th and 7th centuries there were _duces_ at Rome, Naples, Rimini, Venice and Perugia. Gradually, too, they became charged with civil as well as military functions, and even exercised considerable authority in ecclesiastical administration. Under the Byzantine emperors they were the representatives in all causes of the central power. The Roman title of duke was less dignified than that of count (_comes_, companion) which implied an honourable personal relation to the emperor (see COUNT). Both titles were borrowed by the Merovingian kings for the administrative machinery of the Frank empire, and under them the functions of the duke remained substantially unaltered. He was a great civil and military official, charged to watch, in the interests of the crown, over groups of several _comitatus_, or countships, especially in the border provinces. The sphere of the dukes was never rigidly fixed, and their commission was sometimes permanent, sometimes temporary. Under the Carolingians the functions of the dukes remained substantially the same; but with the decay of the royal power in the 10th century, both dukes and counts gained in local authority; the number of dukes became for the time fixed, and finally title and office were made hereditary, the relation to the crown being reduced to that of more or less shadowy vassalage. (See FEUDALISM.)

Side by side with these purely official dukedoms, however, there had continued to exist, or had sprung up, either independently or in more or less of subjection to the Frank rulers, national dukedoms, such as those of the Alemanni, the Aquitanians, and, later, of the Bavarians and Thuringians. These were developed from the early Teutonic custom by which the _herizog_ was elected by the nation as leader for a particular campaign, as in the case of the _heretogas_ who had led the first Saxon invaders into Britain. Tacitus says of the ancient Germans _reges ex nobilitate, duces ex virtute sumunt_; i.e. they elected their dukes for their warlike prowess only, and as purely military chiefs, whereas their kings were chosen from a royal family of divine descent. Sometimes the dukes so chosen succeeded in making their power permanent without taking the style of king. To this national category belong, besides the great German dukedoms, the dukes of Normandy, and the Lombard dukes of Spoleto and Benevento, who traced their origin, not to an administrative office, but to the leadership of Teutonic war bands. With the development of the feudal system the distinction between the official and the national dukedoms was more and more obliterated. By the 13th and 14th centuries the title had become purely territorial, and implied no necessary overlordship over counts and other nobles, who existed side by side with the dukes as tenants-in-chief of the crown. From this time the significance of the ducal title varies widely in different countries. Whenever the crown got the better of the feudal spirit of independence, as in France or Naples, it sank from being a sovereign title to a mere social distinction, implying no political power, and not necessarily any territorial influence. In northern Italy and in Germany, on the other hand, where the crown had proved too weak to combat the forces of disruption, it came ultimately to imply independent sovereignty.

The abolition of the Holy Empire in 1806 removed even the shadow of vassalage from the German reigning dukes, who retain their sovereign status under the new empire. Only one, however, the grand duke of Luxemburg, is now both sovereign and independent. Besides the sovereign dukes in Germany there are certain "mediatized" ducal houses, e.g. that of Ratibor, which share with the dispossessed families of the Italian sovereign duchies certain royal privileges, notably that of equality of blood (_Ebenburtigkeit_). In Italy, where titles of nobility give no precedence at court, that of duke (_duca_) has lost nearly all even of its social significance owing to lavish creations by the popes and minor sovereigns, and to the fact that the title often passes by purchase with a particular estate. Political significance it has none. Some great Italian nobles are dukes, notably the heads of the great Roman ducal families, but not all Italian dukes are great nobles.

In France the title duke at one time implied vast territorial power, as with the dukes of Burgundy, Normandy, Aquitaine and Brittany, who asserted a practical independence against the crown, though it was not till the 12th century that the title duke was definitely regarded as superior to others. At first (in the 10th and 11th centuries) it had no defined significance, and even a baron of the higher nobility called himself in charters duke, count or even marquis, indifferently. In any case the strengthening of the royal power gradually sapped the significance of the title, until on the eve of the Revolution it implied no more than high rank and probably territorial wealth.

There were, under the _ancien regime_, three classes of dukes in France: (1) dukes who were peers (see PEERAGE) and had a seat in the parlement of Paris; (2) hereditary dukes who were not peers; (3) "brevet" dukes, created for life only. The French duke ranks in Spain with the "grandee" (q.v.), and vice versa. In republican France the already existing titles are officially recognized, but they are now no more than the badges of distinguished ancestry. Besides the descendants of the feudal aristocracy there are in France certain ducal families dating from Napoleon I.'s creation of 1806 (e.g. ducs d'Albufera, de Montebello, de Feltre), from Louis Philippe (duc d'Isly, and duc d'Audiffret-Pasquier), and from Napoleon III. (Malakoff, Magenta, Morny).

In England the title of duke was unknown till the 14th century, though in Saxon times the title ealdorman, afterwards exchanged for "earl," was sometimes rendered in Latin as _dux_,[1] and the English kings till John's time styled themselves dukes of Normandy, and dukes of Aquitaine even later. In 1337 King Edward III. erected the county of Cornwall into a duchy for his son Edward the Black Prince, who was thus the first English duke. The second was Henry, earl of Lancaster, Derby, Lincoln and Leicester, who was created duke of Lancaster in 1351. In Scotland the title of duke was first bestowed in 1398 by Robert III. on his eldest son David, who was made duke of Rothesay, and on his brother, who became duke of Albany.

British dukes rank next to princes and princesses of the blood royal, the two archbishops of Canterbury and York, the lord Chancellor, &c., but beyond this precedence they have no special privileges which are not shared by peers of lower rank (see PEERAGE). Though their full style as proclaimed by the herald is "most high, potent and noble prince," and they are included in the _Almanach de Gotha_, they are not recognized as the equals in blood of the crowned or mediatized dukes of the continent, and the daughter of an English duke marrying a foreign royal prince can only take his title by courtesy, or where, under the "house-laws" of certain families, a family council sanctions the match. The eldest son of an English duke takes as a rule by courtesy the second title of his father, and ranks, with or without the title, as a marquess. The other sons and daughters bear the titles "Lord" and "Lady" before their Christian names, also by courtesy. A duke in the British peerage, if not royal, is addressed as "Your Grace" and is styled "the Most Noble." (See ARCHDUKE, GRAND DUKE, and, for the ducal coronet, CROWN AND CORONET.) (W. A. P.)

DUKE OF EXETER'S DAUGHTER, a nickname applied to a 15th-century instrument of torture resembling the rack (q.v.). Blackstone says (_Commentaries_, ii. sec. 326): "The trial by rack is utterly unknown to the law of England, though once when the dukes of Exeter and Suffolk, and other ministers of Henry VI., had laid a design to introduce the civil (i.e. Roman) law into the kingdom as the rule of government, for a beginning thereof they erected a rack for torture, which was called in derision the duke of Exeter's daughter, and still remains in the Tower of London, where it was used as an engine of state, not of law, more than once in Queen Elizabeth's reign. But when, upon the assassination of Villiers, duke of Buckingham, by Felton, it was proposed in the privy council to put the assassin to the rack, in order to discover his accomplices, the judges being consulted, declared unanimously that no such proceeding was allowable by the laws of England."

DUKER, CARL ANDREAS (1670-1752), German classical scholar and jurist, was born at Unna in Westphalia. He studied at the university of Franeker under Jacob Perizonius. In 1700 he was appointed teacher of history and eloquence at the Herborn gymnasium, in 1704 vice-principal of the school at the Hague, and in 1716 he succeeded (with Drakenborch as colleague) to the professorship formerly held by Peter Burmann at Utrecht. After eighteen years' tenure he resigned his post, and lived in retirement at Ysselstein and Vianen. His health finally broke down under excessive study, and he died, almost blind, at the house of a relative in Meiderich near Duisburg, on the 5th of November 1752. His chief classical works were editions of Florus (1722) and Thucydides (1731, considered his best). He brought out the 2nd edition of Perizonius's _Origines Babylonicae et Aegyptiacae_ (1736) and his commentary on Pomponius Mela (1736-1737). Duker was also an authority on ancient law, and published _Opuscula varia de latinitate veterum jurisconsultorum_ (1711), and a revision of the _Leges Atticae_ of S. Petit (1741).

DUKERIES, THE, a name given to a district in the N.W. of Nottinghamshire, England; included within the ancient Sherwood Forest (q.v.). The name is taken from the existence of several adjacent demesnes of noblemen, and the character of the Forest is to some extent preserved here. On the north is the Sheffield-Retford branch of the Great Central railway, serving the town of Worksop, connecting at Retford with the Great Northern railway, while on the south the Great Central railway serves the small market town of Ollerton, and connects with the Great Northern at Dukeries Junction. The following demesnes are comprised in the district. Worksop Manor formerly belonged to the dukes of Norfolk. Welbeck Abbey is the seat of the dukes of Portland, to whom it came from the Cavendish family (dukes of Newcastle); the mansion is mainly classic in style, dating from the early 17th century, but with many subsequent additions; the fifth duke of Portland (d. 1879) built the curious series of subterranean corridors and chambers beneath the grounds. Clumber House, the seat of the dukes of Newcastle, is beautifully placed above a lake in a fine park. Thoresby House is the seat of the earls Manvers, to whom it came on the extinction of the dukedom of Kingston; part of this demesne is a splendid tract of wild woodland.

DUKES, LEOPOLD (1810-1891), Hungarian critic of Jewish literature. He spent about twenty years in England, and from his researches in the Bodleian library and the British Museum (which contain two of the most valuable Hebrew libraries in the world) Dukes was able to complete the work of Zunz (q.v.). The most popular work of Dukes was his _Rabbinische Blumenlese_ (1844), in which he collected the rabbinic proverbs and illustrated them from the gnomic literatures of other peoples. Dukes made many contributions to philology, but his best work was connected with the medieval Hebrew poetry, especially Ibn Gabirol. (I. A.)

DUKINFIELD, a municipal borough of Cheshire, England, within the parliamentary borough of Stalybridge, 6 m. E. of Manchester. Pop. (1901) 18,929. It lies in the densely populated district in the north-east of the county, between Stalybridge and Ashton-under-Lyne, and is served by the London & North Western and Great Central railways. There are extensive collieries, and the other industries include cotton manufactures, calico-printing, hat-making, iron-founding, engineering and the manufacture of firebricks and tiles. A portion remains of the old timbered Dukinfield Hall, in the chapel of which Samuel Eaton (d. 1665) taught the first congregational church in the north of England. The chapel, much enlarged, is still used by this denomination. The borough, incorporated in 1899, is under a mayor, 6 aldermen and 18 councillors. Area, 1405 acres.

DULCIGNO (Servian, _Ultsin_, Turk. _Olgun_), a seaport of Montenegro, on the Adriatic Sea, 8 m. W. of the Albanian frontier. Pop. (1900) about 5000. Shut in by hills and forests, and built partly on a promontory overlooking its bay, partly along the shore, Dulcigno is the prettiest of Montenegrin towns. Its narrow crooked lanes, however, with its bazaars, mosques, minarets and veiled women, give to its picturesqueness a decidedly Turkish air. The old quarter, on the promontory, is walled, and has a medieval castle, once of great strength. Turks form the bulk of the inhabitants, although their numbers decreased steadily after 1880, when the population numbered about 8000. Albanians and Italians are fairly numerous. Dulcigno has a Roman Catholic cathedral and an ancient Latin church. The Austrian Lloyd steamers call at intervals, and some shipbuilding and fishing are carried on; but the harbour lacks shelter and is liable to deposits of silt.

To the Romans, who captured it in 167 B.C., Dulcigno was known as _Ulcinium_ or _Olcinium_; in the middle ages it was a noted haunt of pirates; in the 17th century it was the residence of Sabbatai Zebi (d. 1676), a Jew who declared himself to be the Messiah but afterwards embraced Islam. In 1718 Dulcigno was the scene of a great Venetian defeat. It belonged to the Turks until 1880, when its cession, according to the terms of the treaty of Berlin (1878), was enforced by the "Dulcigno demonstration," in which the fleets of Great Britain, France, Germany, Austria and Russia took part.

DULCIMER (Fr. _tympanon_; Ger. _Hackbrett_, _Cymbal_; Ital. _cembalo_, _timpanon_ or _salterio tedesco_), the prototype of the pianoforte, an instrument consisting of a horizontal sound-chest over which are stretched a varying number of wire strings set in vibration by strokes of little sticks or hammers. The dulcimer differed from the psalterium or psaltery chiefly in the manner of playing, the latter having the strings plucked by means of fingers or plectrum. The shape of the dulcimer is a trapeze or truncated triangle, having the bass strings stretched parallel with the base, which measures from 3 to 4 ft.; the strings decrease gradually in length, the shortest measuring from about 18 to 24 in. at the truncated apex. The sound-board has one or two rose sound-holes; the strings are attached on one side to hitch pins and at the other to the larger tuning pins firmly fixed in the wrest plank. The strings of fine brass or iron wire are in groups of two to five unisons to each note; the vibrating lengths of the strings are determined by means of two bridges. The dulcimer is placed upon a table in front of the performer, who strikes the strings with a little hammer mounted on a metal rod and covered on one side with hard and on the other with soft leather for forte and piano effects. The compass, now chromatic throughout, varies according to the size of the instrument; the large cymbalom of the Hungarian gipsies has a range of four chromatic octaves, .

The origin of the dulcimer is remote, and must be sought in the East. In the bas-reliefs from Kuyunjik, now in the British Museum, are to be seen musicians playing on dulcimers of ten strings with long sticks curved at the ends, and damping the strings with their hands. This is the pisantir of the days of Nebuchadrezzar, translated "psaltery" in Dan. iii. 5, &c., and rendered "psalterion" in the Septuagint, a confusion which has given rise to many misconceptions.[1] In the Septuagint no less than four different instruments are rendered _psalterion_ (from Gr. [Greek: psallo], pluck, pull), i.e. _ugab_, _nebel_, _pisantir_ and _toph_, two stringed, one wind and one percussion. The use of the word in Greek for a musical instrument is not recorded before the 4th century B.C. The modern santir of the Persians, almost identical with the German hackbrett, has a compass from according to Fetis.[2] The Persians place its origin in the highest antiquity. Carl Engel[3] gives an illustration said to be taken from a very old painting.[4]

The dulcimer was extensively used during the middle ages in England, France, Italy, Germany, Holland and Spain, and although it had a distinctive name in each country, it was everywhere regarded as a kind of psalterium. The importance of the method of setting the strings in vibration by means of hammers, and its bearing on the acoustics of the instrument, were recognized only when the invention of the pianoforte had become a matter of history. It was then perceived that the psalterium in which the strings were plucked, and the dulcimer in which they were struck, when provided with keyboards, gave rise to two distinct families of instruments, differing essentially in tone quality, in technique and in capabilities: the evolution of the psalterium stopped at the harpsichord, that of the dulcimer gave us the pianoforte. The dulcimer is described and illustrated by Mersenne,[5] who calls it _psalterion_; it has thirteen courses of pairs of unisons or octaves; the first strings were of brass wire, the others of steel. The curved stick was allowed to fall gently on to the strings and to rebound many times, which, Mersenne remarks, produces an effect similar to the trembling or tremolo of other instruments. Praetorius[6] figures a hackbrett having a body in the shape of a truncated triangle, with a bridge placed between two rose sound-holes, and played by means of two sticks. Another kind of hackbrett[7] (a psaltery), which was played with the fingers, was known to Praetorius. The pantaleon, a double dulcimer, named after the inventor, Pantaleon Hebenstreit of Eisleben, a violinist, had two sound-boards, 185 strings, one scale of overspun catgut, the other of wire. Hebenstreit travelled to Paris with his monster dulcimer in 1705 and played before Louis XIV., who baptized it _Pantaleon_. Quantz[8] and Quirin of Blankenburg[9] both gave descriptions of the instrument. (K. S.)
