DUFF'ERIN AND AVA, Frederick Temple Hamilton-Blackwood, Marquess of,

British statesman and author, son of the fourth Baron Dufferin and a

granddaughter of R. B. Sheridan, born at Florence 1826, died in 1902. He

began his public services in 1855, when he was attached to Earl Russell's

mission to Vienna. Subsequently he was sent as Commissioner to Syria in

connection with the massacre of the Christians (1860); was Under-Secretary

of State for India (1864-6); Under-Secretary for War (1866); Chancellor of

the Duchy of Lancaster (1868-72); Governor-General of Canada (1872-78);

Ambassador at St. Petersburg (1879-81); at Constantinople (1882); sent to

Cairo to settle the affairs of the country after Arabi Pasha's rebellion

(1882-3); Viceroy of India (1884-8); Ambassador to Italy (1889-91); to

France (1891-96). He was elected president of the Royal Geographical

Society in 1878, and Lord Rector of Glasgow University in 1891. Besides

being a noted diplomatist, he was also a popular author. In 1847 he

published _Narrative of a Journey from Oxford to Skibbereen during the year

of the Irish Famine_; in 1860, _Letters from High Latitudes_; also various

pamphlets on Irish questions. In 1888 he was made Marquess of Dufferin and

Ava.--Cf. Sir A. Lyall, _Life of the Marquess of Dufferin and Ava_.

DUFR['E]NOY (d[.u]-fr[.e]-nw[:a]) Pierre Armand, French geologist and

mineralogist, born in 1792, died in 1857. He became director of the school

of mines, and published a great variety of papers on geology and

mineralogy. In 1841 he published, in collaboration with ['E]lie de

Beaumont, a great geological map of France with three volumes of text, and

this was followed by his _Trait['e] de Min['e]ralogie_. He introduced a new

classification of minerals, based on crystallography.

DUFRESNY (d[.u]-fr[=a]-n[=e]), Charles Rivi[`e]re, a French comic poet,

born in 1648, died in 1724. He was clever and versatile, and had great

skill as a landscape-gardener and an architectural designer. Among his

dramatic pieces may be mentioned _L'Esprit de Contradiction_, _Le Mariage

Fait et Rompu_, and _Le Double Veuvage_. He also wrote _Amusements

s['e]rieux et comiques d'un Siamois_, which suggested to Montesquieu his

_Lettres Persanes_.

DUG'DALE, Sir William, an English antiquary, born in 1605 of a good family

in Warwickshire, died 1686. He was made Chester herald in 1644; accompanied

Charles I through the civil war; and after the Restoration received

knighthood, and was appointed garter king-at-arms. In concert with Roger

Dodsworth he produced an important work on English monasteries entitled

_Monasticon Anglicanum_. Among his other works are: _Antiquities of

Warwickshire_; _The Baronage or Peerage of England_; _Origines Judiciales,

or Historical Memoirs of the English Law, Courts of Justice, &c._; a

_History of St. Paul's Cathedral_; and various minor writings. He also

completed and published the second volume of Spelman's _Concilia_.

[Illustration: Dugong (_Halic[)o]r[=e] dugong_)]

DU'GONG, a herbivorous mammal, the _Halic[)o]r[=e] dugong_, belonging to

the ord. Sirenia, which also includes the manatees. It is a native of the

Indian and Australian seas; possesses a tapering body ending in a

crescent-shaped fin, and is said sometimes to attain a length of 20 feet,

though generally it is about 7 or 8 feet in length. The fore-limbs are in

the form of flippers; hind-limbs are absent. The skin is thick and smooth,

with a few scattered bristles; the colour bluish above and white beneath.

Its food consists of marine plants; it yields little or no oil, but is

hunted by the Malays for its flesh, which resembles veal, and is tender and

palatable. It has been suggested that the appearance of this animal has

given rise to the legends of mermaids and mermen.

DUGUAY-TROUIN (d[:u]-g[=a]-tr[:o]-an), Ren['e], a distinguished French

seaman, born at St. Malo in 1673, died at Paris 1736. As commander of a

privateer he took many prizes from the British between 1690 and 1697. He

then entered the royal marine as a captain, and signalized himself so much

in the Spanish War that the king granted him letters of nobility, in which

it was stated that he had captured more than 300 merchant ships and twenty

ships of war. By the capture of Rio de Janeiro (1711) he brought the Crown

more than 25,000,000 francs. Under Louis XV he rendered important services

in the Levant and the Mediterranean.

DU GUESCLIN (d[:u]-g[=a]-klan), Bertrand, Constable of France, born about

1314, died 1380. Mainly to him must be attributed the expulsion of the

English from Normandy, Guienne, and Poitou. He was captured by Chandos at

the battle of Auray in 1364, and ransomed for 100,000 francs. While serving

in Spain against Peter the Cruel, he was made prisoner by the English Black

Prince, but was soon liberated. For his services in Spain he was made

Constable of Castile, Count of Trastamare, and Duke of Molinas; and in 1370

he was made Constable of France.

DUIKERBOK, species of Cephalophus, small South African antelopes with short

horns (none in the female), and a tuft of stiff hairs between them.

DUISBURG (d[:o]'is-b[u:]r_h_), a flourishing town in Rhenish Prussia, 13

miles north of D[:u]sseldorf. It is an ancient place, believed to be of

Roman origin. It early rose to be a free town, and became a member of the

Hanseatic League. It possesses a beautiful church of the fifteenth century,

and has iron manufactories, engineering works, chemical works, and cotton

and woollen mills; and a large trade greatly facilitated by a canal

communicating with the Rhine, which is about 2 miles distant. Pop. 229,483.

DUJARDIN (d[.u]-zh[.a]r-da[n.]), Karel, a Dutch artist, who excelled in

painting landscapes, animals, and scenes in low life, born in 1640 at

Amsterdam, died at Venice 1678. His paintings are rare, and command high

prices. His masterpiece, _The Charlatans_ (1657), is in the Louvre.

DUKE (Fr. _duc_, Sp. _duque_, It. _duca_, all from Lat. _dux_, leader,

commander), a title belonging originally to a military leader. In Britain

it is the highest rank in the peerage. Royal dukes have a special status

and precedence. The first hereditary duke in England was the Black Prince,

created by his father, Edward III, in 1336. The duchy of Cornwall was

bestowed upon him, and was thenceforward attached to the eldest son of the

king, who is considered a duke by birth. The duchy of Lancaster was soon

after conferred on Edward's third son, John of Gaunt, and hence arose the

special privileges which these two duchies still in part retain. A duke in

the British peerage, not of royal rank, is styled 'your grace', or 'my Lord

Duke'; his wife is a duchess. (See _Address, Forms of_.) The coronet

consists of a richly-chased gold circle, having on its upper edge eight

golden leaves of a conventional type called strawberry leaves; the cap of

crimson velvet is closed at the top with a gold tassel, lined with

sarsenet, and turned up with ermine. (See _Coronet_.) At various periods

and in different continental countries the title duke (_Herzog_ in Germany)

was given to the actual sovereigns of small states. The titles 'grand-duke'

and 'grand-duchess', 'archduke' and 'archduchess', were in use also on the

European continent, especially in Russia and Austria until 1918. In the

Bible the word _dukes_ is used (_Gen._ xxxvi) for the _duces_ of the

_Vulgate_.

DUKHOBORZI (d[u:]_h_-o-bor'ts[=e]), a Russian sect of religious mystics

which arose in the eighteenth century. The name means 'spirit-fighters', as

the sect was accused by the orthodox priests of fighting against the spirit

of God. They reject the doctrine of the Trinity, of the deity of Christ,

hold property in common, and refuse oaths and military service, thus

resembling Quakers. In 1899 a body of several thousands emigrated to

Canada, where they received territory in Assiniboia and Saskatchewan.

DUKINFIELD, or DUCKINFIELD, a municipal borough, England, county Cheshire,

separated by the Tame from Ashton-under-Lyne, and mostly within Stalybridge

parliamentary borough. Collieries, cotton-factories, brickworks, and

tileworks give employment to the population. Pop. (municipal borough),

19,426.

DULCE (d[u:]l's[=a]), a lake of Guatemala, on the east coast, communicating

with the Gulf of Honduras by the lakelet el Golfete. It is about 30 miles

long by 12 broad, and affords profitable turtle hunting.

DULCIGNO (d[u:]l-ch[=e]n'y[=o]), a small seaport town, formerly in Albania,

now in Montenegro, on the Adriatic, the seat of a Roman Catholic Bishop. It

was captured by the Austrians in 1916, and retaken by Italian troops in

1918. Pop. 5000.

[Illustration: Italian Dulcimer]

DUL'CIMER, one of the most ancient musical instruments, used in almost all

parts of the world. The modern instrument consists of a shallow

trapezium-shaped box without a top, across which runs a series of wires,

tuned by pegs at the sides, and played on by being struck by two

cork-headed hammers. It is in much less common use in Europe now than it

was a century or two ago, and is interesting chiefly as being the prototype

of the piano. It is still, however, occasionally to be met with on the

Continent at fairs in the country, and in England in the hands of street

musicians. It was known in Persia and Arabia under the name of _santir_,

and was introduced into Europe by the Crusaders. The Hebrew psaltery is

supposed to have been a variety of the dulcimer.

DUL'CINISTS, followers of Dulcinus, a layman of Lombardy, in the fourteenth

century, who preached the reign of the Holy Ghost, affirming that the

Father had reigned till Christ's incarnation, and that the Son's reign

terminated in 1300. He was followed by a great many people to the Alps,

where he and his wife were taken and burned by order of Clement IV.

DULCITOL, or DULCITE, is an alcohol closely allied to the sugars. It is

found in Madagascar manna, from which it is extracted by boiling water.

DULI'A (Gr. _douleia_, service, from _doulos_, a slave), an inferior kind

of worship or adoration, as that paid to saints and angels in the Roman

Catholic Church. The Catholics recognize different degrees of worship. The

lowest degree is the _dulia_, which is given to saints and angels.

_Hyperdulia_ is reserved for the Virgin alone; and _latria_ is given to God

and to each person of the Trinity.

DULSE, a red sea-weed, the _Rhodymenia palm[=a]ta_, used in some parts of

Scotland as an edible. It has a reddish-brown, or purple, leathery,

veinless frond, several inches long, and is found at low water adhering to

the rocks. It is an important plant to the Icelanders, and is stored by

them in casks to be eaten with fish. In Kamchatka a fermented liquor is

made from it. In the south of England the name is given to the _Iridaea

ed[=u]lis_, also an edible red sea-weed.

DULUTH (du-luth'), a town of the United States, capital of St. Louis

county, Minnesota, at the south-west extremity of Lake Superior. The

Northern Pacific and Lake Superior and Mississippi railways terminate here;

and extensive docks and other works have been constructed, affording a

convenient outlet for the surrounding wheat region. Pop. 97,077.

DULWICH (dul'ich), a suburb of London, in County Surrey, about 5 miles

south of London Bridge, giving name to a parliamentary division of the

borough of Camberwell; noticeable on account of its school, _Dulwich

College_, called the 'College of God's Gift,' founded as a charitable

institution in 1619 by the actor Edward Allen or Alleyn. Four parishes were

benefited by the charity: St. Luke's, Middlesex; St. Botolph's,

Bishopsgate; St. Saviour's, Southwark; and St. Giles', Camberwell. Having

outlived its usefulness, in 1857 an Act was passed by which the college was

reconstituted. It now consists of two branches, the educational and the

eleemosynary, between which the surplus revenue is divided in the

proportion of three-fourths to the former and one-fourth to the latter. The

educational branch comprises two schools, the upper and the lower; the

former giving boys a high-class education (lower fees for those of the

privileged parishes), and having a number of scholarships and exhibitions.

The eleemosynary branch maintains a certain number of resident and

non-resident poor people. The original revenues were only L800, but now

amount to L20,000. Dulwich College is celebrated for its pictures, many of

which were bequeathed by the founder; but the greater and more valuable

portion of them was the bequest of Sir Francis Bourgeois, a

landscape-painter, who died in 1810. The collection includes many fine

pictures of the Dutch school.

DUMA, or DOUMA, the Lower House of the former Russian Parliament, the Upper

House being the Council of the Empire. In 1905 Tsar Nicholas II granted his

country a Constitution, promising that responsible Government would be

established, and that no law would be made effective without the consent of

the Duma. The first Duma accordingly met in 1906, and was to have had the

power of a Parliament in Constitutional countries. The Legislative Assembly

could make new laws, modify existing ones, issue the national Budget, &c.,

but had no right to alter the fundamental laws of the empire. In spite of

the promises, however, given by the Tsar, the Imperial Government paid no

attention to the demands of the Assembly, and when the criticisms of the

Deputies became too loud, the first Duma was dissolved. A second Duma

assembled the next year, but its members, in consequence of governmental

restrictions on elections, were mostly Conservatives. In the opinion of the

Government, however, even the second Duma was too Liberal in its

tendencies, and it was promptly dissolved. The third Duma, which met in

1907, and whose members were mostly landed proprietors, retired officers,

and priests, was absolutely subservient to the autocratic Government, and,

from that date to the outbreak of the Russian Revolution in 1917, the power

and influence of the Russian Duma were almost nil. The Duma ceased to exist

on 7th Nov., 1917, when the Bolsheviks came into power, and the Government

of Commissaries of the People was set up.

DUMAS (d[.u]-m[:a]), Alexandre (called _Dumas P[`e]re_), French novelist

and dramatist, born at Villers-Cotterets 1803, died at Puys, near Dieppe,

1870. He was the son of a republican general, and grandson of the Marquis

de la Pailleterie and a negress, Tiennette Dumas. In 1823 he went to Paris,

and obtained an assistant-secretaryship from the Duke of Orleans,

afterwards Louis Philippe. He soon began to write for the stage, and in

1829 scored his first success with his drama _Henri III et sa cour_. It was

produced when the battle between the Romanticists and the Classicists was

at its height, and hailed as a triumph by the former school. The same year

appeared his _Christine_, and in quick succession _Antony_, _Richard

d'Arlington_, _T['e]r['e]sa_, _La Tour de Nesle_, _Catharine Howard_, and

_Mlle de Belle-Isle_. Dumas had now become a noted Parisian character. The

critics fought over the merits of his pieces, and the scandal-mongers over

his prodigality and _galanteries_. Turning his attention to romance, he

produced a series of historical romances, among which may be mentioned: _Le

b[^a]tard de Maul['e]on_; _Isabelle de Bavi[`e]re_; _Les Deux Dianes_; _La

Reine Margot_; _Les Trois Mousquetaires_, with its continuations _Vingt Ans

Apr[`e]s_ and the later _Vicomte de Bragelonne_. His _Monte-Cristo_ and

several others are also well known to English readers through translations.

Several historical works were also written by him: _Louis XIV et son

Si[`e]cle_, _Le Regent et Louis XV_, _Le Drame de '93_, _Florence et les

M['e]dicis_, &c. The works which bear his name amount to some 1200 volumes,

including about 60 dramas; but the only claim he could lay to a great

number of the productions issued under his name was that he either sketched

the plot or revised them before going to press. He earned vast sums of

money, but his recklessness and extravagance eventually reduced him to the

adoption of a shifty, scheming mode of living. His _M['e]moires_, begun in

1852, present interesting sketches of literary life during the Restoration,

but display intense egotism. In 1860 he accompanied Garibaldi in the

expedition which freed Naples from the Bourbons. He died at the residence

of his son, and was buried in Villers-Cotterets in 1872. Dumas was

remarkable for his creative rather than for his artistic genius, and

although he frequently squandered his gifts, he was admired even by the

highly cultured, such as Thackeray and others.--BIBLIOGRAPHY: H. Blaze de

Bury, _Alexandre Dumas: sa vie, son temps, son oeuvre_; A. B. Davidson,

_Alexandre Dumas p[`e]re: his Life and Works_.

DUMAS, Alexandre, son of the above, born 1824, died in 1895, novelist and

dramatist. His works treat mostly of the relations between vice and morals.

His first novels, _La Dame aux Cam['e]lias_ and _Diane de Lys_, were very

successful, as were also the plays which were founded on them. His dramas,

which are much superior to his novels, deal satirically with the

characters, follies, and manners of French society. He was thus a pioneer

in the 'comedy of manners'. His plays, besides his dramatized novel _La

Dame aux Cam['e]lias_, which marked a date in the history of the French

stage, and which supplied Verdi with the plot for _La Traviata_, are: _Le

demi-monde_, _Le fils naturel_, _L'Ami des femmes_, _La princesse Georges_,

and _L'['E]trang[`e]re_.

DUMAS, Matthieu, French soldier and military writer, born in 1753, died in

Paris 1837. He early entered the French cavalry, took part in the War of

American Independence, and was employed in the Levant and in Holland. At

the commencement of the Revolution he assisted Lafayette in organizing the

National Guard. On the triumph of the extreme party in 1797 Dumas was

proscribed, but made his escape to Holstein, where he wrote the first part

of his _Pr['e]cis des ['E]v['e]nements Militaires_, a valuable source for

the history of the period of which it treats (1798-1807). He was recalled

from exile by Napoleon, who had become First Consul. His first employment

was to organize the reserve for the army of Italy. In 1802 he was appointed

State Councillor; in 1805 he became general of division, and was shortly

afterwards Neapolitan minister in the service of Joseph Bonaparte. In 1808

he was actively employed in the arrangements for the war against Austria,

fought in the battles of Essling and Wagram, and arranged the terms of the

armistice of Znaim. He held the office of General Intendant of the army in

the campaign of 1812. After the Restoration Louis XVIII appointed him

Councillor of State, and gave him several important appointments connected

with the army. In 1830 he aided in bringing on the revolution of July, and

after the fall of Charles X he obtained the chief command of all the

national guards of France, together with a peerage. He published a

translation of Napier's _History of the Peninsular War_.

DU MAURIER (d[.u]-m[=o]'ri-[=a]), George Louis Palmella Busson, artist and

writer, was born in Paris 1834, died in 1896. He was the son of an English

mother and a Frenchman who had been naturalized as a British subject. At

the age of seventeen he took up the study of chemistry in London, but soon

adopted art as a profession. After studying in Belgium and France, he

returned to London, and soon began to contribute drawings to _Punch_, _Once

a Week_, _Cornhill Magazine_, &c. He succeeded Leech on _Punch_, and became

famous chiefly through his drawings for that publication. He also

illustrated various books, and wrote three novels, _Trilby_, _Peter

Ibbetson_, and _The Martian_. His elder son, Guy Du Maurier, born in 1865,

killed in France in 1915, was the author of _An Englishman's Home_ (1909).

DUMBA, Konstantin Theodor, Austro-Hungarian diplomatist, who became

conspicuous as an agent of German propaganda in the United States during

the European War. He went as Ambassador to the United States in 1913, and

at the outbreak of the war endeavoured to organize a vast conspiracy there,

with a view to hampering the productions of munitions for the Allies.

Abusing his position of Ambassador, he planned explosions and strikes in

American factories. On 1st Sept., 1915, J. F. J. Archibald, an American

newspaper correspondent, was arrested at Falmouth, and among the papers

found upon him was a letter from Dr. Dumba to Baron Burian, Austrian

Minister for Foreign Affairs, wherein the former suggested a plan of

crippling the munition factories in America by creating strikes. President

Wilson then demanded his recall, and he left the United States in Oct.,

1915, Great Britain granting him a safe conduct.

DUMBAR'TON, a royal and parliamentary burgh and seaport, Scotland, chief

town of Dumbarton county, stands on the Leven near its junction with the

Clyde, 16 miles W.N.W. of Glasgow. Shipbuilding is carried on to a great

extent, and there are foundries and engine-works. Dumbarton unites with

Port-Glasgow, Renfrew, Rutherglen, and Kilmarnock in sending a member to

Parliament. Originally it was called Alcluyd, and it was the chief town of

Cumbria or Strathclyde. Pop. 21,989. A little to the south is the famous

rock and castle of Dumbarton, rising above the Clyde. The rock, which is of

basalt, is 240 feet in height, and about 1 mile in circumference at the

base. It is one of the fortresses stipulated to be kept in repair by the

Act of Union, and the barracks contain accommodation for 150 men. There has

been a stronghold here from the earliest times, and the fortress of

Dumbarton occupied an important place in Scottish

history.--_Dumbartonshire_, the county of Dumbarton, is partly maritime,

partly inland, consisting of two detached portions, the larger and most

westerly lying between the Clyde, Loch Long, and Loch Lomond, and the far

smaller portion being about 4 miles east of the former, and comprising only

two parishes. More than half the area of the county is occupied by

mountains, some of them attaining a height of upwards of 3000 feet. The

lower lands are fertile, and in general well cultivated. More than one-half

of Loch Lomond and fully two-thirds of the islands in it belong to

Dumbartonshire. The Gareloch, an arm of the Firth of Clyde, forms a part of

the county into a peninsula. The principal rivers are the Leven, from Loch

Lomond, and the Kelvin, both belonging to the Clyde system. The chief

minerals are coal, limestone, ironstone, and slate, all of which are

wrought more or less. On the banks of the Leven and elsewhere are extensive

cotton printing and bleaching establishments; and there are extensive

shipbuilding yards along the Clyde. Besides Dumbarton, the chief town, the

county contains the towns of Helensburgh and Kirkintilloch, and the

manufacturing villages of Alexandria, Renton, and Bonhill. Vestiges of the

Roman wall of Antoninus still exist. The county returns one member to the

House of Commons. Pop. 139,831.

DUMB-CANE, a plant of the ord. Araceae, the _Dieffenbachia seguina_, of the

West Indies, so called from its acridity causing swelling of the tongue

when chewed, and destroying the power of speech.

DUMDUM, a military village and extensive cantonment, Hindustan, province of

Bengal, 4-1/2 miles E.N.E. of Calcutta. The village is famous as being the

scene of the first open manifestation of the sepoys against the greased

cartridges, which led to the mutiny of 1857. Pop. 12,000.

DUMDUM BULLET (so called from the arsenal at Dumdum, a small village 4-1/2

miles from Calcutta), a hollow-nosed bullet which expands on impact, and so

causes an ugly wound. It was used in Indian frontier fighting to stop the

rushes of fanatical tribesmen. While the term 'Dumdum' bullet should

strictly only be applied to hollow-nosed bullets, it is popularly applied

to any kind of expanding bullet. Ordinary bullets can be converted into

expanding ones by means of filing the cupro-nickel envelope until the lead

core is exposed, by means of slitting the envelope at the shoulders, or

simply by reversing the bullet in its socket. Expanding bullets are

considered legitimate in big-game shooting, but in the Declaration signed

at the Hague, 29th July, 1899, Germany expressly promised not to use such

bullets in warfare. In spite of this the Germans freely used bullets of

this kind in the European War.
