DE CAMP, JOSEPH (1858- ), American portrait and figure painter, was

born in Cincinnati, Ohio, in 1858. He was a pupil of Frank Duveneck and

of the Royal Academy of Munich; became a member of the society of Ten

American Painters, and a teacher in the schools of the Pennsylvania

Academy of Fine Arts, Philadelphia, and the Boston Museum of Fine Arts;

and painted important mural decorations in the Philadelphia city hall.

DECAMPS, ALEXANDRE GABRIEL (1803-1860), French painter, was born in

Paris on the 3rd of March 1803. In his youth he travelled in the East,

and reproduced Oriental life and scenery with a bold fidelity to nature

that made his works the puzzle of conventional critics. His powers,

however, soon came to be recognized, and he was ranked along with

Delacroix and Vernet as one of the leaders of the French school. At the

Paris Exhibition of 1855 he received the grand or council medal. Most of

his life was passed in the neighbourhood of Paris. He was passionately

fond of animals, especially dogs, and indulged in all kinds of field

sports. He died on the 22nd of August 1860 in consequence of being

thrown from a vicious horse while hunting at Fontainebleau. The style of

Decamps was characteristically and intensely French. It was marked by

vivid dramatic conception, by a manipulation bold and rapid, sometimes

even to roughness, and especially by original and startling use of

decided contrasts of colour and of light and shade. His subjects

embraced an unusually wide range. He availed himself of his travels in

the East in dealing with scenes from Scripture history, which he was

probably the first of European painters to represent with their true and

natural local background. Of this class were his "Joseph sold by his

Brethren," "Moses taken from the Nile," and his scenes from the life of

Samson, nine vigorous sketches in charcoal and white. Perhaps the most

impressive of his historical pictures is his "Defeat of the Cimbri,"

representing with wonderful skill the conflict between a horde of

barbarians and a disciplined army. Decamps produced a number of genre

pictures, chiefly of scenes from French and Algerine domestic life, the

most marked feature of which is humour. The same characteristic attaches

to most of his numerous animal paintings. He painted dogs, horses, &c.,

with great fidelity and sympathy; but his favourite subject was monkeys,

which he depicted in various studies and sketches with a grotesque

humour that could scarcely be surpassed. Probably the best known of all

his works is "The Monkey Connoisseurs," a clever satire of the jury of

the French Academy of Painting, which had rejected several of his

earlier works on account of their divergence from any known standard.

The pictures and sketches of Decamps were first made familiar to the

English public through the lithographs of Eugene le Roux.

See Moreau's _Decamps et son oeuvre_ (Paris, 1869).

DECAPOLIS, a league of ten cities ([Greek: deka poleis]) with their

surrounding district, situated with one exception on the eastern side of

the upper Jordan and the Sea of Tiberias. Being essentially a

confederation of _cities_ it is impossible precisely to fix Decapolis as

a _region_ with definite boundaries. The names of the original ten

cities are given by Pliny; these are as follows: Damascus, Philadelphia,

Raphana, Scythopolis (= Beth-Shan, now _Beisan_, west of Jordan),

Gadara, Hippos, Dion, Pella, Gerasa and Kanatha. Of these Damascus alone

retains its importance. Scythopolis (as represented by the village of

Beisan) is still inhabited; the ruins of Pella, Gerasa and Kanatha

survive, but the other sites are unknown or disputed. Scythopolis, being

in command of the communications with the sea and the Greek cities on

the coast, was the most important member of the league. The league

subsequently received additions and some of the original ten dropped

out. In Ptolemy's enumeration Raphana has no place, and nine, such as

Kapitolias, Edrei, Bosra, &c., are added. The purpose of the league was

no doubt mutual defence against the marauding Bedouin tribes that

surrounded them. These were hardly if at all checked by the Semitic

kinglings to whom the Romans delegated the government of eastern

Palestine.

It was probably soon after Pompey's campaign in 64-63 B.C. that the

Decapolis league took shape. The cities comprising it were united by

the main roads on which they lay, their respective spheres of influence

touching, if not overlapping, one another. A constant communication was

maintained with the Mediterranean ports and with Greece, and there was a

vigorous municipal life which found expression in literature, in

athletic contests, and in a thriving commerce, thus carrying a truly

Hellenic influence into Perea and Galilee. From Josephus we learn that

the cities were severally subject to the governor of Syria and taxed for

imperial purposes; some of them afterwards came under Herod's

jurisdiction, but reserved the substantial rights granted them by

Pompey.

Land_, chap. xxviii. (R. A. S. M.)

DECASTYLE (Gr. [Greek: deka], ten, and [Greek: stylos], column), the

architectural term given to a temple where the front portico has ten

columns; as in the temple of Apollo Didymaeus at Miletus, and the

portico of University College, London. (See TEMPLE.)

DECATUR, STEPHEN (1779-1820), American naval commander, was born at

Sinnepuxent, Maryland, on the 5th of January 1779, and entered the

United States navy as a midshipman in 1798. He was promoted lieutenant a

year later, and in that rank saw some service in the short war with

France. In 1803 he was in command of the "Enterprise," which formed part

of Commodore Preble's squadron in the Mediterranean, and in February

1804 led a daring expedition into the harbour of Tripoli for the purpose

of burning the U.S. frigate "Philadelphia" which had fallen into

Tripolitan hands. He succeeded in his purpose and made his escape under

the fire of the batteries with a loss of only one man wounded. This

brilliant exploit earned him his captain's commission and a sword of

honour from Congress. Decatur was subsequently engaged in all the

attacks on Tripoli between 1804 and 1805. In the War of 1812 his ship

the "United States" captured H.M.S. "Macedonian" after a desperate

fight, and in 1813 he was appointed commodore to command a squadron in

New York harbour, which was soon blockaded by the British. In an attempt

to break out in February 1815 Decatur's flagship the "President" was cut

off and after a spirited fight forced to surrender to a superior force.

Subsequently he commanded in the Mediterranean against the corsairs of

Algiers, Tunis and Tripoli with great success. On his return he was made

a navy commissioner (November 1815), an office which he held until his

death, which took place in a duel with Commodore James Barron at

Bladensburg, Md., on the 22nd of March 1820.

See Mackenzie, _Life of Decatur_ (Boston, 1846).

DECATUR, a city and the county-seat of Macon county, Illinois, U.S.A.,

in the central part of the state, near the Sangamon river, about 39 m.

E. of Springfield. Pop. (1890) 16,841; (1900) 20,754, of whom 1939 were

foreign-born; (1910 census) 31,140. Decatur is served by the Cincinnati,

Hamilton & Dayton, the Illinois Central, the Wabash (which maintains car

shops here), and the Vandalia railways, and is connected with Danville,

Saint Louis, Springfield, Peoria, Bloomington and Champaign by the

Illinois Traction System (electric). Decatur has three large parks and a

public library; and S.E. of Fairview Park, with a campus of 35 acres, is

the James Millikin University (co-educational; Cumberland Presbyterian),

founded in 1901 by James Millikin, and opened in 1903. The university

comprises schools of liberal arts, engineering (mechanical, electrical,

and civil), domestic economy, fine and applied arts, commerce and

finance, library science, pedagogy, music, and a preparatory school; in

1907-1908 it had 936 students, 440 being in the school of music. Among

the city's manufactures are iron, brass castings, agricultural

implements, flour, Indian corn products, soda fountains, plumbers'

supplies, coffins and caskets, bar and store fixtures, gas and electric

light fixtures, street cars, and car trucks. The value of the city's

factory products increased from $5,133,677 in 1900 to $8,667,302 in

1905, or 68.8%. The city is also an important shipping point for

agricultural products (especially grain), and for coal taken from the

two mines in the city and from mines in the surrounding country. The

first settlement in Decatur was made in 1829, and the place was

incorporated in 1836. On the 22nd of February 1856 a convention of

Illinois editors met at Decatur to determine upon a policy of opposition

to the Kansas-Nebraska Bill. They called a state convention, which met

at Bloomington, and which is considered to have taken the first step

toward founding the Republican party in Illinois.

DECAZES, ELIE, DUC (1780-1860), French statesman, was born at Saint

Martin de Laye in the Gironde. He studied law, became a judge in the

tribunal of the Seine in 1806, was attached to the cabinet of Louis

Bonaparte in 1807, and was counsel to the court of appeal at Paris in

1811. Immediately upon the fall of the empire he declared himself a

Royalist, and remained faithful to the Bourbons through the Hundred

Days. He made the personal acquaintance of Louis XVIII. during that

period through Baron Louis, and the king rewarded his energy and tact by

appointing him prefect of police at Paris on the 7th of July 1815. His

marked success in that difficult position won for him the ministry of

police, in succession to Fouche, on the 24th of September. In the

interval he had been elected deputy for the Seine (August 1815) and both

as deputy and as minister he led the moderate Royalists. His formula was

"to royalize France and to nationalize the monarchy." The Moderates were

in a minority in the chamber of 1815, but Decazes persuaded Louis XVIII.

to dissolve the house, and the elections of October 1816 gave them a

majority. During the next four years Decazes was called upon to play the

leading role in the government. At first, as minister of police he had

to suppress the insurrections provoked by the ultra-Royalists (the White

Terror); then, after the resignation of the duc de Richelieu, he took

the actual direction of the ministry, although the nominal president was

General J. J. P. A. Dessolle (1767-1828). He held at the same time the

portfolio of the interior. The cabinet, in which Baron Louis was

minister of finance, and Marshal Gouvion Saint Cyr remained minister of

war, was entirely Liberal; and its first act was to suppress the

ministry of police, as Decazes held that it was incompatible with the

regime of liberty. His reforms met with the strong hostility of the

Chamber of Peers, where the ultra-Royalists were in a majority, and to

overcome it he got the king to create sixty new Liberal peers. He then

passed the laws on the press, suppressing the censorship. By

reorganization of the finances, the protection of industry and the

carrying out of great public works, France regained its economic

prosperity, and the ministry became popular. But the powers of the Grand

Alliance had been watching the growth of Liberalism in France with

increasing anxiety. Metternich especially ascribed this mainly to the

"weakness" of the ministry, and when in 1819 the political elections

still further illustrated this trend, notably by the election of the

celebrated Abbe Gregoire, it began to be debated whether the time had

not come to put in force the terms of the secret treaty of

Aix-la-Chapelle. It was this threat of foreign intervention, rather than

the clamour of the "Ultras," that forced Louis XVIII. to urge a change

in the electoral law that should render such a "scandal" as Gregoire's

election impossible for the future. Dessolle and Louis, refusing to

embark on this policy, now resigned; and Decazes became head of the new

ministry, as president of the council (November 1819). But the exclusion

of Gregoire from the chamber and the changes in the franchise embittered

the Radicals without conciliating the "Ultras." The news of the

revolution in Spain in January 1820 added fuel to their fury; it was the

foolish and criminal policy of the royal favourite that had once more

unchained the demon of revolution. Decazes was denounced as the new

Sejanus, the modern Catiline; and when, on the 13th of February, the

duke of Berry was murdered, clamorous tongues loudly accused him of

being an accomplice in the crime. Decazes, indeed, foreseeing the storm,

at once placed his resignation in the king's hands. Louis at first

refused. "They will attack," he exclaimed, "not your system, my dear

son, but mine." But in the end he was forced to yield to the importunity

of his family (February 17th); and Decazes, raised to the rank of duke,

passed into honourable exile as ambassador to Great Britain.

This ended Decazes's meteoric career of greatness. In December 1821 he

returned to sit in the House of Peers, when he continued to maintain

his Liberal opinions. After 1830 he adhered to the monarchy of July, but

after 1848 he remained in retirement. He had organized in 1826 a society

to develop the coal and iron of the Aveyron, and the name of Decazeville

was given in 1829 to the principal centre of the industry. He died on

the 24th of October 1860.

His son, LOUIS CHARLES ELIE DECAZES, duc de Glucksberg (1819-1886), was

born at Paris, and entered the diplomatic career. He became minister

plenipotentiary at Madrid and at Lisbon, but the revolution of 1848

caused him to withdraw into private life, from which he did not emerge

until in 1871 he was elected deputy to the National Assembly by the

Gironde. There he sat in the right centre among the Orleanists, and was

chosen by the duc de Broglie as minister of foreign affairs in November

1873. He voted with the Orleanists the "Constitutional Laws" of 1875,

and approved of MacMahon's parliamentary _coup d'etat_ on the 16th of

May 1877. He was re-elected deputy in October 1877 by the arrondissement

of Puget-Theniers, but his election was annulled by the chamber, and he

was not re-elected. He died on the 16th of September 1886.

(1899), and his "L'ambassade du duc Decazes" in the _Revue des deux

mondes_ for 1899.

DECAZEVILLE, a town of south-central France, in the department of

Aveyron, 34 m. N.W. of Rodez by the Orleans railway. Pop. (1906) 9749.

It possesses iron mines and is the centre of the coal-fields of the

Aveyron, which supply the ironworks established by the Duc Decazes,

minister of Louis XVIII. A statue commemorates the founder.

DECCAN (Sans. _Dakshina_, "the South"), a name applied, according to

Hindu geographers, to the whole of the territories in India situated to

the south of the river Nerbudda. In its more modern acceptation,

however, it is sometimes understood as comprising only the country lying

between that river and the Kistna, the latter having for a long period

formed the southern boundary of the Mahommedan empire of Delhi.

Assigning it the more extended of these limits, it comprehends the whole

of the Indian peninsula, and in this view the mountainous system,

consisting of the Eastern and Western Ghats, constitutes the most

striking feature of the Deccan. These two mountain ranges unite at their

northern extremities with the Vindhya chain of mountains, and thus is

formed a vast triangle supporting at a considerable elevation the

expanse of table-land which stretches from Cape Comorin to the valley of

the Nerbudda. The surface of this table-land slopes from west to east,

as indicated by the direction of the drainage of the country,--the great

rivers, the Cauvery, Godavari, Kistna and Pennar, though deriving their

sources from the base of the Western Ghats, all finding their way into

the Bay of Bengal through fissures in the Eastern Ghats.

_History._--The detailed and authentic history of the Deccan only begins

with the 13th century A.D. Of the early history the main facts

established are the Aryan invasion (c. 700 B.C.), the growth of the

Maurya empire (250 B.C.) and the invasion (A.D. 100) of the Scythic

tribes known as the Sakas, Pahlavas and Yavanas, which led to the

establishment of the power of the Kshaharata satraps in western India.

In addition to this, modern study of monuments and inscriptions has

recovered the names, and to a certain extent the records, of a

succession of dynasties ruling in the Deccan; of these the most

conspicuous are the Cholas, the Andhras or Satavahanas, the Chalukyas,

the Rashtrakutas and the Yadavas of Devagiri (Deogiri). (See INDIA:

_History_; BOMBAY; PRESIDENCY: _History_; INSCRIPTIONS: _Indian_.) In

1294 Ala-ud-Din Khilji, emperor of Delhi, invaded the Deccan, stormed

Devagiri, and reduced the Yadava rajas of Maharashtra to the position of

tributary princes (see DAULATABAD), then proceeding southward overran

Telingana and Carnata (1294-1300). With this event the continuous

history of the Deccan begins. In 1307, owing to non-payment of tribute,

a fresh series of Mussulman incursions began, under Malik Kafur, issuing

in the final ruin of the Yadava power; and in 1338 the reduction of the

Deccan was completed by Mahommed ben Tughlak. The imperial sway was,

however, of brief duration. Telingana and Carnata speedily reverted to

their former masters; and this defection on the part of the Hindu states

was followed by a general revolt of the Mussulman governors, resulting

in the establishment in 1347 of the independent Mahommedan dynasty of

Bahmani, and the consequent withdrawal of the power of Delhi from the

territory south of the Nerbudda. In the struggles which ensued, the

Hindu kingdom of Telingana fell bit by bit to the Bahmani dynasty, who

advanced their frontier to Golconda in 1373, to Warangal in 1421, and to

the Bay of Bengal in 1472. On the dissolution of the Bahmani empire

(1482), its dominions were distributed into the five Mahommedan states

of Golconda, Bijapur, Ahmednagar, Bidar and Berar. To the south of these

the great Hindu state of Carnata or Vijayanagar still survived; but

this, too, was destroyed, at the battle of Talikota (1565), by a league

of the Mahommedan powers. These latter in their turn soon disappeared.

Berar had already been annexed by Ahmednagar in 1572, and Bidar was

absorbed by Bijapur in 1609. The victories of the Delhi emperors, Akbar,

Shah Jahan and Aurangzeb, crushed the rest. Ahmednagar was incorporated

in the Mogul empire in 1598, Bijapur in 1686, and Golconda in 1688. The

rule of the Delhi emperors in the Deccan did not, however, long survive.

In 1706 the Mahrattas acquired the right of levying tribute in southern

India, and their principal chief, the Peshwa of Poona, became a

practically independent sovereign. A few years later the emperor's

viceroy in Ahmednagar, the nizam-al-mulk, threw off his allegiance and

established the seat of an independent government at Hyderabad (1724).

The remainder of the imperial possessions in the peninsula were held by

chieftains acknowledging the supremacy of one or other of these two

potentates. In the sequel, Mysore became the prize of the Mahommedan

usurper Hyder Ali. During the contests for power which ensued about the

middle of the 18th century between the native chiefs, the French and the

English took opposite sides. After a brief course of triumph, the

interests of France declined, and a new empire in India was established

by the British. Mysore formed one of their earliest conquests in the

Deccan. Tanjore and the Carnatic were shortly after annexed to their

dominions. In 1818 the forfeited possessions of the Peshwa added to

their extent; and these acquisitions, with others which have more

recently fallen to the paramount power by cession, conquest or failure

of heirs, form a continuous territory stretching from the Nerbudda to

Cape Comorin. Its length is upwards of 1000 m., and its extreme breadth

exceeds 800. This vast tract comprehends the chief provinces now

distributed between the presidencies of Madras and Bombay, together with

the native states of Hyderabad and Mysore, and those of Kolhapur,

Sawantwari, Travancore, Cochin and the petty possessions of France and

Portugal.

DECELEA (Gr. [Greek: Dekeleia]), an Attic deme, on the pass which led

over the east end of Mt. Parnes towards Oropus and Chalcis. From its

position it has a commanding view over the Athenian plain. Its eponymous

hero, Decelus, was said to have indicated to the Tyndaridae, Castor and

Pollux, the place where Theseus had hidden their sister Helen at

Aphidnae; and hence there was a traditional friendship between the

Deceleans and the Spartans (Herodotus ix. 73). This tradition, together

with the advice of Alcibiades, led the Spartans to fortify Decelea as a

basis for permanent occupation in Attica during the later years of the

Peloponnesian War, from 413-404 B.C. Its position enabled them to harass

the Athenians constantly, and to form a centre for fugitive slaves and

other deserters. The royal palace of Tatoi has been built on the site.

DECEMBER (Lat. _decem_, ten), the last month of the year. In the Roman

calendar, traditionally ascribed to Romulus, the year was divided into

ten months, the last of which was called December, or the _tenth_ month,

and this name, though etymologically incorrect, was retained for the

last or twelfth month of the year as now divided. In the Romulian

calendar December had thirty days; Numa reduced the number to

twenty-nine; Julius Caesar added two days to this, giving the month its

present length. The _Saturnalia_ occurred in December, which is

therefore styled "acceptus geniis" by Ovid (_Fasti_, iii. 58); and this

also explains the phrase of Horace "libertate Decembri utere" (_Sat._

ii. 7). Martial applies to the month the epithet _canus_ (hoary), and

Ovid styles it _gelidus_ (frosty) and _fumosus_ (smoky). In the reign of

Commodus it was temporarily styled _Amazonius_, in honour of the

emperor's mistress, whom he had had painted as an Amazon. The Saxons

called it _winter-monath_, winter month, and _heligh-monath_, holy

month, from the fact that Christmas fell within it. Thus the modern

Germans call it _Christmonat_. The 22nd of December is the date of the

winter solstice, when the sun reaches the tropic of Capricorn.

DECEMVIRI ("the ten men"), the name applied by the Romans to any

official commission of ten. The title was often followed by a statement

of the purpose for which the commission was appointed, e.g. _Xviri

legibus scribundis, stlitibus judicandis, sacris faciundis_.

I. Apart from such qualification, it signified chiefly the temporary

commission which superseded all the ordinary magistrates of the Republic

from 451 to 449 B.C., for the purpose of drawing up a code of laws. In

462 B.C. a tribune proposed that the appointment of a commission to draw

up a code expressing the legal principles of the administration was

necessary to secure for the _plebs_ a hold over magisterial caprice.

Continued agitation to this effect resulted in an agreement in 452 B.C.

between patricians and plebeians that decemvirs should be appointed to

draw up a code, that during their tenure of office all other

magistracies should be in abeyance, that they should not be subject to

appeal, but that they should be bound to maintain the laws which

guaranteed by religious sanctions the rights of the plebs. The first

board of decemvirs (apparently consisting wholly of patricians) was

appointed to hold office during 451 B.C.; and the chief man among them

was Appius Claudius. Livy (iii. 32) says that only patricians were

eligible. Mommsen, however, held that plebeians were legally eligible,

though none were actually appointed for 451. The decemvirs ruled with

singular moderation, and submitted to the _Comitia Centuriata_ a code of

laws in ten headings, which was passed. So popular were the decemvirs

that another board of ten was appointed for the following year, some of

whom, if the extant list of names is correct, were certainly plebeians.

These added two more to the ten laws of their predecessors, thus

completing the Laws of the Twelve Tables (see ROMAN LAW). But their rule

then became violent and tyrannical, and they fell before the fury of the

_plebs_, though for some reason, not easily understood, they continued

to have the support of the patricians. They were forced to abdicate (449

B.C.), and the ordinary magistrates were restored.

II. The judicial board of decemvirs (_stlitibus judicandis_) formed a

civil court of ancient origin concerned mainly with questions bearing on

the status of individuals. They were originally a body of jurors which

gave a verdict under the presidency of the praetor (q.v.), but

eventually became annual minor magistrates of the Republic, elected by

the _Comitia Tributa_.

III. The priestly board of decemvirs (_sacris faciundis_) was an outcome

of the claim of the _plebs_ to a share in the administration of the

state religion. Five of the decemvirs were patricians, and five

plebeians. They were first appointed in 367 B.C. instead of the

patrician _duumviri_ who had hitherto performed these duties. The board

was increased to fifteen in the last century of the Republic. Its chief

function was the care of the Sibylline books, and the celebration of the

games of Apollo (Livy x. 8) and the Secular Games (Tac. _Ann._ xi. 11).

IV. Decemvirs were also appointed from time to time to control the

distribution of the public land (_agris dandis adsignandis_; see

AGRARIAN LAWS).

DECHEN, ERNST HEINRICH KARL VON (1800-1889), German geologist, was born

in Berlin on the 25th of March 1800, and was educated in the university

in that city. He subsequently studied mining in Bochum and Essen, and

was in 1820 placed in the mining department of the Prussian state,

serving on the staff until 1864, and becoming director in 1841 when he

was stationed at Bonn. In early years he made journeys to study the

mining systems of other countries, and with this object he visited

England and Scotland in company with Karl von Oeynhausen (1797-1865). In

the course of his work he paid special attention to the coal-formation

of Westphalia and northern Europe generally, and he greatly furthered

the progress made in mining and metallurgical works in Rhenish Prussia.

He made numerous contributions to geological literature; notably the

following:--_Geognostische Umrisse der Rheinlander zwischen Basel und

Mainz mit besonderer Rucksicht auf das Vorkommen des Steinsalzes_ (with

von Oeynhausen and La Roche), 2 vols. (Berlin, 1825); _Geognostische

Fuhrer in das Siebengebirge am Rhein_ (Bonn, 1861); _Die nutzbaren

Mineralien und Gebirgsarten im deutschen Reiche_ (1873). But his main

work was a geological map of Rhenish Prussia and Westphalia in 35 sheets

on the scale of 1 : 80,000, issued with two volumes of explanatory text

(1855-1882). He published also a small geological map of Germany (1869).

He died at Bonn on the 15th of February 1889. (H. B. W.)

DECIDUOUS (from Lat. _decidere_, to fall down), a botanical and

zoological term for "falling in season," as of petals after flowering,

leaves in autumn, the teeth or horns of animals, or the wings of

insects.

DECIMAL COINAGE.[1] Any currency in which the various denominations of

coin are arranged in multiples or submultiples of ten (Lat. _decem_),

with reference to a standard unit, is a decimal system. Thus if the

standard unit be 1 the higher coins will be 10, 100, 1000, &c., the

lower .1, .01, .001, &c. In a perfect system there would be no breaks or

interpolations, but the actual currencies described as "decimal" do not

show this rigid symmetry. In France the standard unit--the franc--has

the 10 franc and the 100 franc pieces above it; the 10 centime below it;

there are also, however, 50 franc, 20 franc, 5 franc, 2 franc pieces as

well as 50 and 20 centime ones. Similar irregularities occur in the

German and United States coinages, and indeed in all countries in which

a decimal system has been established. Popular convenience has compelled

this departure from the strict decimal form.

Subject to these practical modifications the leading countries of the

world (Great Britain and India are the chief exceptions) have adopted

decimal coinage. The United States led the way (1786 and 1792) with the

dollar as the unit, and France soon followed (1799 and 1803), her system

being extended to the countries of the Latin Union (1865). The German

empire (1873), the Scandinavian States (1875), Austria-Hungary (1870,

developed in 1892) and Russia (1839 and 1897) are further adherents to

the decimal system. The Latin-American countries and Japan (1871) have

also adopted it.

In England proposals for decimalizing the coinage have long been under

discussion at intervals. Besides the inconvenience of altering the

established currency, the difficulty of choosing between the different

schemes propounded has been a considerable obstacle. One plan took the

farthing as a base: then 10 farthings = 1 doit (2(1/2)d.), 10 doits = 1

florin (2s. 1d.), 10 florins = 1 pound (20s. 10d.). The advantages

claimed for this scheme were (1) the preservation of the smaller coins

(the penny = 4 farthings); and (2) the avoidance of interference with

the smaller retail prices. Its great disadvantage was the destruction of

the existing unit of value--the pound--and the consequent disturbance of

all accounts. A second proposal would retain the pound as unit and the

florin, but would subdivide the latter into 100 "units" (or farthings

reduced 4%) and introduce a new coin = 10 units (2.4d.). By it the unit

of account would remain as at present, and the shilling (as 50 units)

would continue in use. The alteration of the bronze and several silver

coins, and the need of readjusting all values and prices expressed in

pence, formed the principal difficulties. A third scheme, which was

connected with the assimilation of English to French and American money,

proposed the establishment of an 8s. gold coin as unit, with the

tenpenny or franc and the penny (reduced by 4%) as subdivisions. The new

coin would be equivalent to 10 francs or (by an anticipated reduction of

the dollar) 2 dollars. None of these plans has gained any great amount

of popular support.
