DINARD, a seaside town of north-western France, in the department of

Ille-et-Vilaine. The town, which is the chief watering-place of

Brittany, is situated on a rocky promontory at the mouth of the Rance

opposite St Malo, which is about 1 m. distant. It is a favourite resort

of English and Americans as well as of the French, its attractions being

the beauty of its situation, the mildness of the climate and the good

bathing. It has two casinos and numerous luxurious hotels and elegant

villas. Together with the adjoining watering-place of St Enogat, Dinard

has a population of 4882 (1906).

DINDIGUL, a town of British India, in the Madura district of Madras, 880

ft. above the sea, 40 m. from Madura by rail. Pop. (1901) 25,182.

Dindigul has risen into importance as the centre of a trade in tobacco

and manufacture of cigars, which are exported to England. There are two

large European cigar factories here. The town has manufactures of silk,

muslin and blankets, and an export trade in hides and cardamoms; and

there is a large native Christian population, with two churches. The

ancient fort, well preserved, stands on a rock rising 350 ft. above the

town; this was formerly a position of great strategic importance,

commanding passes into Madura from Coimbatore, and figured prominently

in the military operations of the Mahrattas in the 17th and 18th

centuries, and of Hyder Ali in 1755 seq., being thrice captured by the

British (1767, 1783, 1790). After the two first captures it was restored

to Hyder Ali under treaty; after the third it was ceded to the East

India Company.

KARL WILHELM DINDORF (1802-1883), German classical scholar, was born at

Leipzig on the 2nd of January 1802. From his earliest years he showed a

strong taste for classical studies, and after completing F. Invernizi's

edition of Aristophanes at an early age, and editing several grammarians

and rhetoricians, was in 1828 appointed extraordinary professor of

literary history in his native city. Disappointed at not obtaining the

ordinary professorship when it became vacant in 1833, he resigned his

post in the same year, and devoted himself entirely to study and

literary work. His attention had at first been chiefly given to

Athenaeus, whom he edited in 1827, and to the Greek dramatists, all of

whom he edited separately and combined in his _Poetae scenici Graeci_

(1830 and later editions). He also wrote a work on the metres of the

Greek dramatic poets, and compiled special lexicons to Aeschylus and

Sophocles. He edited Procopius for Niebuhr's _Corpus_ of the Byzantine

writers, and between 1846 and 1851 brought out at Oxford an important

edition of Demosthenes; he also edited Lucian and Josephus for the Didot

classics. His last important editorial labour was his _Eusebius of

Caesarea_ (1867-1871). Much of his attention was occupied by the

republication of Stephanus's _Thesaurus_ (Paris, 1831-1865), chiefly

executed by him and his brother Ludwig, a work of prodigious labour and

utility. His reputation suffered somewhat through the imposture

practised upon him by the Greek Constantine Simonides, who succeeded in

deceiving him by a fabricated fragment of the Greek historian Uranius.

The book was printed, and a few copies had been circulated, when the

forgery was discovered, just in time to prevent its being given to the

world under the auspices of the university of Oxford. Shortly after the

death of his brother, he lost all his property and his library by rash

speculations. He died on the 1st of August 1883.

His brother LUDWIG (1805-1871) was born at Leipzig on the 3rd of January

1805, and died there on the 6th of September 1871. He never held any

academical position, and led so secluded a life that many doubted his

existence, and declared that he was a mere pseudonym. The important

share which he took in the edition of the _Thesaurus_ is nevertheless

authenticated by his own signature to his contributions. He also

published valuable editions of Polybius, Dio Cassius and other Greek

historians.

D'INDY, PAUL-MARIE-THEODORE-VINCENT (1851- ), French musical composer,

was born in Paris, on the 27th of March 1851. He studied composition and

the organ at the Paris Conservatoire under Cesar Franck, and obtained

the grand prize offered by the city of Paris in 1885 with _Le Chant de

la Cloche_, a dramatic legend after Schiller. His principal works,

beside the above, are the symphonic trilogy _Wallenstein_, the symphonic

works entitled _Saugefleurie_, _La Foret enchantee_, _Istar_, _Symphonie

sur un air montagnard francais_; overture to _Anthony and Cleopatra_;

_Ste Marie Magdeleine_, a cantata; _Attendez-moi sous l'orme_, a one-act

opera; _Fervaal_, a musical drama in three acts. Vincent d'Indy is

perhaps the most prominent among the disciples of Cesar Franck. Imbued

with very high aims, he was always guided by a lofty ideal, and few

musicians have attained so complete a mastery over the art of

instrumentation. His music, however, lacks simplicity, and can never

become popular in the widest sense. His opera _Fervaal_, which is styled

"action musicale", is constructed upon the system of _Leit-motifs_. Its

legendary subject recalls both _Parsifal_ and _Tristan_, and the music

is also suggestive of Wagnerian influence. D'Indy can scarcely be

considered so typical a representative of modern French music as his

juniors Alfred Bruneau, the composer of _Le Reve_, _L'Attaque du

moulin_, _Messidor_, or Gustave Charpentier, the author of _Louise_, who

chose subjects of modern life for their operatic works.

DINEIR, a small town in Asia Minor, built amidst the ruins of

Celaenae-Apamea, near the sources of the Maeander (Menderes). It is the

terminus of the Smyrna-Aidin-Dineir railway. Pop. 1400. (See APAMEA.)

DINGELSTEDT, FRANZ VON (1814-1881), German poet and dramatist, was born

at Halsdorf, in Hesse Cassel, on the 30th of June 1814. Having studied

at the university of Marburg, he became in 1836 a master at the Lyceum

in Cassel, from which he was transferred to Fulda in 1838. In 1839 he

produced a novel, _Unter der Erde_, which obtained considerable success,

and in 1841 published the book by which he is best remembered, the

_Lieder eines kosmopolitischen Nachtwachters_. These poems, animated as

they are by a spirit of bitter opposition to everything that savours of

despotism, were an effective contribution to the political poetry of the

day. The popularity of this book determined Dingelstedt to take up a

literary career, and in 1841 he obtained an appointment on the staff of

the _Augsburger allgemeine Zeitung_. In 1843, however, the satirist of

German princes accepted, to the general surprise, the appointment of

private librarian to the king of Wurttemberg, and in the same year he

married the celebrated Bohemian opera singer, Jenny Lutzer. In 1845 he

published a volume of poems, some of which, treating of modern life,

possessed great literary rather than strictly poetical merit. A

subsequent collection, published in 1852, attracted little attention.

The success of his tragedy _Das Haus der Barneveldt_ (1850) obtained for

him the position of intendant at the court theatre at Munich, where he

soon became the centre of literary society. He incurred, however, the

animosity of the Jesuit clique at the court, and in 1856 was suddenly

dismissed on the most frivolous charges. A similar position was offered

to him at Weimar through the influence of Liszt, and he remained there

until 1867. His administration was most successful, and he especially

distinguished himself by presenting all Shakespeare's historical plays

upon the stage in an unbroken cycle. In 1867 he became director of the

court opera house in Vienna, and in 1872 of the Hofburgtheater, a

position he held until his death on the 15th of May 1881. Among his

other works may be noticed an autobiographical sketch of his Munich

career, entitled _Munchener Bilderbogen_ (1879), _Die Amazone_, an art

novel of considerable merit (1869), translations of several of

Shakespeare's comedies, and several writings dealing with questions of

practical dramaturgy. He was ennobled in 1867 by the king of Bavaria and

in 1876 was created _Freiherr_ by the emperor of Austria.

Dingelstedt's _Samtliche Werke_ appeared in 12 vols. (1877-1878), but

this edition is far from complete. On his life see, besides the

autobiography mentioned above, J. Rodenberg, _Heimaterinnerungen an F.

Dingelstedt_ (Berlin, 1882), and by the same author, _F. Dingelstedt,

Blatter aus seinem Nachlass_ (2 vols., 1891). Also an essay by A.

Stern in _Zur Literatur der Gegenwart_ (Leipzig, 1880).

DINGHY, or DINGEY (from the Hindu _d[=e]ng[=i]_ a small boat, the

diminutive of _denga_, a sloop or coasting vessel), a boat of greatly

varying size and shape, used on the rivers of India; the term is applied

also, in certain districts, to a larger boat used for coasting purposes.

The name was adopted by the merchantmen trading with India, and is now

generally used to designate the small extra boat kept for general

purposes on a man-of-war or merchant vessel, and also, on the Thames,

for small pleasure boats built for one or two pairs of sculls.

DINGLE, a seaport and market town of county Kerry, Ireland, in the west

parliamentary division, the terminus of the Tralee and Dingle railway.

Pop. (1901) 1786. This may be considered the most westerly town in the

United Kingdom unless Knightstown at Valencia Island be excepted; it

lies on the south side of the northernmost of the great promontories

which protrude into the Atlantic on the south-western coast of Ireland,

on the fine natural harbour of Dingle Bay, in a wild hilly district

abundant in relics of antiquity. The town, which is the centre of a

considerable fishing industry, especially in mackerel, was in the 16th

century of no little importance as a seaport; it had also a noted

manufacture of linen. It was incorporated by Queen Elizabeth, and

returned two members to the Irish parliament until the Union.

DINGO, a name applied apparently by Europeans to the warrigal, or native

Australian dog, the Canis dingo of J. F. Blumenbach. The dingo is a

stoutly-built, rather short-legged, sandy-coloured dog, intermediate in

size between a jackal and a wolf, and measuring about 51 in. in total

length, of which the tail takes up about eleven. In general appearance

it is very like some of the pariah dogs of India and Egypt; and, except

on distributional grounds, there is no reason for regarding it as

specifically distinct from such breeds. Dingos, which are found both

wild and tame, interbreed freely with European dogs introduced into the

country, and it may be that the large amount of black on the back of

many specimens may be the result of crossing of this nature.

The main point of interest connected with the dingo relates to its

origin; that is to say, whether it is a member of the indigenous

Australian fauna (among which it is the only large placental mammal), or

whether it has been introduced into the country by man. There seems to

be no doubt that fossilized remains of the dingo occur intermingled with

those of the extinct Australian mammals, such as giant kangaroos, giant

wombats and the still more gigantic _Diprotodon_. And since remains of

man have apparently not yet been detected in these deposits, it has been

thought by some naturalists that the dingo must be an indigenous

species. This was the opinion of Sir Frederick McCoy, by whom the

deposits in question were regarded as probably of Pliocene age. A

similar view is adopted by D. Ogilvy in a _Catalogue of Australian

Mammals_, published at Sydney in 1892; the writer going however one step

further and expressing the belief that the dingo is the ancestor of all

domesticated dogs. The latter contention cannot for a moment be

sustained; and there are also strong arguments against the indigenous

origin of the dingo. That the animal now occurs in a wild state is no

argument whatever as to its being indigenous, seeing that a domesticated

breed introduced by man into a new country abounding in game would

almost certainly revert to the wild state. The apparent absence of human

remains in the beds yielding dingo teeth and bones (which are almost

certainly not older than the Pleistocene) is of only negative value, and

liable to be upset by new discoveries. Then, again (as has been pointed

out by R. I. Pocock in the first part of the _Kennel Encyclopaedia_,

1907), the absence of any really wild species of the typical group of

the genus _Canis_ between Burma and Siam on the one hand and Australia

on the other is a very strong argument against the dingo being

indigenous, seeing that, whether brought by man or having travelled

thither of its own accord, the dingo must have reached its present

habitat by way of the Austro-Malay archipelago. If it had followed that

route in the course of nature, it is inconceivable that it would not

still be found on some portions of the route. On the supposition that

the dingo was introduced by man, we have now fairly decisive evidence

that the native Australian, in place of being (as formerly supposed) a

member of the negro stock, is a low type of Caucasian allied to the

Veddahs of Ceylon and the Toalas of Celebes. Consequently the Australian

natives must be presumed to have reached the island-continent by way of

Malaya; and if this be admitted, nothing is more likely than that they

should have been accompanied by pariah dogs of the Indian type.

Confirmation of this is afforded by the occurrence in the mountains of

Java of a pariah-like dog which has reverted to an almost completely

wild condition; and likewise by the fact that the old voyagers met with

dogs more or less similar to the dingo in New Guinea, New Zealand and

the Solomon and certain other of the smaller Pacific islands. On the

whole, then, the most probable explanation of the case is that the dingo

is an introduced species closely allied to the Indian pariah dog.

Whether the latter represents a truly wild type now extinct, cannot be

determined. If so, all pariahs should be classed with the Australian

warrigal under the name of _Canis dingo_. If, on the other hand,

pariahs, and consequently the dingo, cannot be separated specifically

from the domesticated dogs of western Europe, then the dingo should be

designated _Canis familiaris dingo_. (R. L.*)

DINGWALL, a royal and police burgh and county town of the shire of Ross

and Cromarty, Scotland. Pop. (1901) 2519. It is situated near the head

of Cromarty Firth where the valley of the Peffery unites with the

alluvial lands at the mouth of the Conon, 18-1/2 m. N.W. of Inverness by

the Highland railway. Its name, derived from the Scandinavian

_Thingvollr_, "field or meeting-place of the _thing_," or local

assembly, preserves the Norse origin of the town; its Gaelic designation

is Inverpefferon, "the mouth of the Peffery." The 18th-century town

house, and some remains of the ancient mansion of the once powerful

earls of Ross still exist. There is also a public park. An obelisk, 57

ft. high, was erected over the grave of the 1st earl of Cromarty. The

town belongs to the Wick district group of parliamentary burghs. It is a

flourishing distributing centre and has an important corn market and

auction marts. Some shipping is carried on at the harbour at the mouth

of the Peffery, about a mile below the burgh. Branch lines of the

Highland railway run to Strathpeffer and to Strome Ferry and Kyle of

Lochalsh (for Skye). Alexander II. created Dingwall a royal borough in

1226, and its charter was renewed by James IV. On the top of Knockfarrel

(Gaelic, _cnoc_, hill; _faire_, watch, or guard), a hill about 3 m. to

the west, is a large and very complete vitrified fort with ramparts.

DINKA (called by the Arabs _Jange_), a widely spread negro people

dwelling on the right bank of the White Nile to about 12 deg. N., around

the mouth of the Babr-el-Ghazal, along the right bank of that river and

on the banks of the lower Sobat. Like the Shilluk, they were greatly

harried from the north by Nuba-Arabic tribes, but remained comparatively

free owing to the vast extent of their country, estimated to cover

40,000 sq. m., and their energy in defending themselves. They are a tall

race with skins of almost blue black. The men wear practically no

clothes, married women having a short apron, and unmarried girls a

fringe of iron cones round the waist. They tattoo themselves with tribal

marks, and extract the lower incisors; they also pierce the ears and lip

for the attachment of ornaments, and wear a variety of feather, iron,

ivory and brass ornaments. Nearly all shave the head, but some give the

hair a reddish colour by moistening it with animal matter. Polygamy is

general; some headmen have as many as thirty or more wives; but six is

the average number. They are great cattle and sheep breeders; the men

tend their beasts with great devotion, despising agriculture, which is

left to the women; the cattle are called by means of drums. Save under

stress of famine cattle are never killed for food, the people subsisting

largely on durra. The Dinkas reverence the cow, and snakes, which they

call "brothers." Their folklore recognizes a good and evil deity; one of

the two wives of the good deity created man, and the dead go to live

with him in a great park filled with animals of enormous size. The evil

deity created cripples. The Dinka came, in 1899, under the control of

the Sudan government, justice being administered as far as possible in

accord with tribal custom. A compendium of Dinka laws was compiled by

Captain H. D. E. O'Sullivan.

See G. A. Schweinfurth, _The Heart of Africa_ (1874); W. Junker,

_Travels in Africa_, Eng. edit. (London, 1890-1892); _The

Anglo-Egyptian Sudan_, edited by Count Gleichen (London, 1905).

DINKELSBUHL, a town of Germany, in the kingdom of Bavaria, on the

Wornitz, 16 m. N. from Nordlingen, on the railway to Dombuhl. Pop. 5000.

It is an interesting medieval town, still surrounded by old walls and

towers, and has an Evangelical and two Roman Catholic churches. Notable

is the so-called _Deutsches Haus_, the ancestral home of the counts of

Drechsel-Deufstetten, a fine specimen of the German renaissance style of

wooden architecture. There are a Latin and industrial school, several

benevolent institutions, and a monument to Christoph von Schmid

(1768-1854), a writer of stories for the young. The inhabitants carry on

the manufacture of brushes, gloves, stockings and gingerbread, and deal

largely in cattle.

Fortified by the emperor Henry I., Dinkelsbuhl received in 1305 the same

municipal rights as Ulm, and obtained in 1351 the position of a free

imperial city, which it retained till 1802, when it passed to Bavaria.

Its municipal code, the _Dinkelsbuhler Recht_, published in 1536, and

revised in 1738, contained a very extensive collection of public and

private laws.

DINNER, the chief meal of the day, eaten either in the middle of the

day, as was formerly the universal custom, or in the evening. The word

"dine" comes through Fr. from Med. Lat. _disnare_, for _disjejunare_, to

break one's fast (_jejunium_); it is, therefore, the same word as Fr.

_dejeuner_, to breakfast, in modern France, to take the midday meal,

_diner_ being used for the later repast. The term "dinner-wagon,"

originally a movable table to hold dishes, is now used of a two-tier

sideboard.

DINOCRATES, a great and original Greek architect, of the age of

Alexander the Great. He tried to captivate the ambitious fancy of that

king with a design for carving Mount Athos into a gigantic seated

statue. This plan was not carried out, but Dinocrates designed for

Alexander the plan of the new city of Alexandria, and constructed the

vast funeral pyre of Hephaestion. Alexandria was, like Peiraeus and

Rhodes (see HIPPODAMUS), built on a regular plan; the streets of most

earlier towns being narrow and confused.

DINOFLAGELLATA, so called by O. Butschli (= the CILIOFLAGELLATA of E.

Claparide and H. Lachmann), a group of Protozoa, characterized as

Mastigophora, provided with two flagella, the one anterior extended in

locomotion, the other coiled round its base, or lying in a transverse

groove. The body is bounded by a firm pellicle, often supplemented by an

armour ("lorica") of cuticular cellulose plates, with usually a marked

longitudinal groove from which the anterior flagellum springs, and an

oblique or spiral transverse groove for the second flagellum. In

_Polykrikos_ (fig. 2, 9) there are eight transverse grooves each with

its flagellum. The armour-plates are often exquisitely sculptured, and

may be produced into spines or perpendicular plates to give greater

surface extension, as we find in other plankton organisms. The cortical

plasma may protrude pseudopodia in the longitudinal groove; it contains

trichocysts in several species, true nematocysts in _Polykrikos_. It

contains chromatophores in many species, coloured by a mixed lipochrome

pigment which appears to be distinct from diatomin. The endoplasm is

ramified between alveoli; it contains a large nucleus (in _Polykrikos_

there are eight nuclei, accompanied by smaller, more numerous bodies

regarded by O. Butschli as micro-nuclei). Besides the other spaces are

definite rounded or oval vacuoles with a permanent pellicular wall

termed by Schutt "pusules"; these open by a duct or ducts into the

longitudinal groove. They enlarge and diminish, and are possibly

excretory like the "contractile vacuoles" of other Protista; though it

has been suggested that by their communication with the medium they

subserve nutrition. Nutrition is of course holozoic or saprophytic in

the colourless forms, holophytic in the coloured; but these divergent

methods are exhibited by different species of the same genus, or even by

individuals of one and the same species under different conditions.

Binary fission has been widely observed, both in the active condition or

after loss of the flagella: it differs from that of true Flagellates in

not being longitudinal, but transverse or oblique (fig, 2, 2). Repeated

fission (brood-formation) within a cyst has also been observed, as in

_Pyrocystis_ and _Ceratium_; and possibly the chains of _Ceratium_ and

other (fig. 2, 5 and 6) genera are due to the non-separation of the

brood-cells. Conjugation of adults has been observed in several species,

the most complete account being that of Zederbauer on _Ceratium

hirundinella_ (marine): either mate puts forth a tube which meets and

opens into that of the other (as in some species of _Chlamydomonas_ and

Desmids); the two cell-bodies fuse in this tube, and encyst to form a

resting zygospore. The Dinoflagellates are relatively large for

Mastigophora, many attaining 50 [mu] (1/500") in length. The majority are

marine; but some genera (_Ceratium_, _Peridinium_) include fresh-water

species. Many are highly phosphorescent and some by their abundance

colour the water of the sea or pool which they dwell in. Like so many

coloured Protista, they frequently possess a pigmented "eye-spot" in

which may be sunk a spheroidal refractive body ("lens").

The affinities of the Dinoflagellata are certainly with those

Cryptomonadine Flagellates which possess two unequal flagella; the

zoospores or young of the Cystoflagellates are practically colourless

Dinoflagellates.

1. _Gymnodiniaceae_: body naked, or with a simple cellulose or

gelatinous envelope; both grooves present. _Pyrocystis_ (Murray),

often encysted, spherical or crescentic, becoming free within cyst

wall, and escaping whole or after brood-divisions as a form like

_Gymnodinium_; _Gymnodinium_ (Stein); _Hemidinium_ (Stein);

_Pouchetia_ (Schutt) (fig. 2, 7) with complex eye-spot; to this group

we may refer _Polykrikos_ (Butschli) (fig. 2, 9), with its metameric

transverse grooves and flagella.

2. _Prorocentraceae_ (Schutt) ( = the Adinida of Bergh); body

surrounded by a firm shell of two valves without a girdle band;

transverse groove absent; transverse flagellum coiled round base of

longitudinal. _Exuviaeella_ (Cienk.) (fig. 2, 3); _Prorocentrum_

(Ehrb.) (fig. 2, 4).

3. _Peridiniaceae_ (Schutt); body with a shell of plates, a girdle

band along the transverse groove, in which the transverse flagellum

lies. Genera, _Peridinium_ (Ehrb.) (fig. 1), fresh-water and marine;

_Ceratium_ (Schrank) (fig. 2, 5, 6), fresh-water and marine;

_Citharistes_ (Stein); _Ornithoceras_ (Claparede and Lachmann) (fig.

2, 1).

DINOTHERIUM, an extinct mammal, fossil remains of which occur in the

Miocene beds of France, Germany, Greece and Northern India. These

consist chiefly of teeth and the bones of the head. An entire skull,

obtained from the Lower Pliocene beds of Eppelsheim, Hesse-Darmstadt, in

1836, measured 4-1/2 ft. in length and 3 ft. in breadth, and indicates an

animal exceeding the elephant in size. The upper jaw is apparently

destitute of incisor and canine teeth, but possesses five molars on each

side, with a corresponding number in the jaw beneath. The most

remarkable feature, however, consists in the front part of the lower jaw

being bent downwards and bearing two tusk-like incisors also directed

downwards and backwards. _Dinotherium_ is a member of the group

Proboscidea, of the line of descent of the elephants.

DINWIDDIE, ROBERT (1693-1770), English colonial governor of Virginia,

was born near Glasgow, Scotland, in 1693. From the position of customs

clerk in Bermuda, which he held in 1727-1738, he was promoted to be

surveyor-general of the customs "of the southern ports of the continent

of America," as a reward for having exposed the corruption in the West

Indian customs service. In 1743 he was commissioned to examine into the

customs service in the Barbadoes and exposed similar corruption there.

In 1751-1758 he was lieutenant-governor of Virginia, first as the deputy

of Lord Albemarle and then, from July 1756 to January 1758, as deputy

for Lord Loudon. He was energetic in the discharge of his duties, but

aroused much animosity among the colonists by his zeal in looking after

the royal quit-rents, and by exacting heavy fees for the issue of

land-patents. It was his chief concern to prevent the French from

building in the Ohio Valley a chain of forts connecting their

settlements in the north with those on the Gulf of Mexico; and in the

autumn of 1753 he sent George Washington to Fort Le Boeuf, a newly

established French post at what is now Waterford, Pennsylvania, with a

message demanding the withdrawal of the French from English territory.

As the French refused to comply, Dinwiddie secured from the reluctant

Virginia assembly a grant of L10,000 and in the spring of 1754 he sent

Washington with an armed force toward the forks of the Ohio river "to

prevent the intentions of the French in settling those lands." In the

latter part of May Washington encountered a French force at a spot

called Great Meadows, near the Youghiogheny river, in what is now

south-western Pennsylvania, and a skirmish followed which precipitated

the French and Indian War. Dinwiddie was especially active at this time

in urging the co-operation of the colonies against the French in the

Ohio Valley; but none of the other governors, except William Shirley of

Massachusetts, was then much concerned about the western frontier, and

he could accomplish very little. His appeals to the home government,

however, resulted in the sending of General Edward Braddock to Virginia

with two regiments of regular troops; and at Braddock's call Dinwiddie

and the governors of Massachusetts, New York, Pennsylvania and Maryland

met at Alexandria, Virginia, in April 1755, and planned the initial

operations of the war. Dinwiddie's administration was marked by a

constant wrangle with the assembly over money matters; and its obstinate

resistance to military appropriations caused him in 1754 and 1755 to

urge the home government to secure an act of parliament compelling the

colonies to raise money for their protection. In January 1758 he left

Virginia and lived in England until his death on the 27th of July 1770

at Clifton, Bristol.

_The Official Records of Robert Dinwiddie, Lieutenant-Governor of

Virginia_ (1751-1758), published in two volumes, at Richmond, Va., in

1883-1884, by the Virginia Historical Society, and edited by R. A.

Brock, are of great value for the political history of the colonies in

this period.

DIO CASSIUS (more correctly CASSIUS DIO), COCCEIANUS (c. A.D. 150-235),

Roman historian, was born at Nicaea in Bithynia. His father was Cassius

Apronianus, governor of Dalmatia and Cilicia under Marcus Aurelius, and

on his mother's side he was the grandson of Dio Chrysostom, who had

assumed the surname of Cocceianus in honour of his patron the emperor

Cocceius Nerva. After his father's death, Dio Cassius left Cilicia for

Rome (180) and became a member of the senate. During the reign of

Commodus, Dio practised as an advocate at the Roman bar, and held the

offices of aedile and quaestor. He was raised to the praetorship by

Pertinax (193), but did not assume office till the reign of Septimius

Severus, with whom he was for a long time on the most intimate footing.

By Macrinus he was entrusted with the administration of Pergamum and

Smyrna; and on his return to Rome he was raised to the consulship about

220. After this he obtained the proconsulship of Africa, and again on

his return was sent as legate successively to Dalmatia and Pannonia. He

was raised a second time to the consulship by Alexander Severus, in 229;

but on the plea of ill health soon afterwards retired to Nicaea, where

he died. Before writing his history of Rome ([Greek: Rhomaika] or

[Greek: Rhomaike Historia]), Dio Cassius had dedicated to the emperor

Severus an account of various dreams and prodigies which had presaged

his elevation to the throne (perhaps the [Greek: Enodia] attributed to

Dio by Suidas), and had also written a biography of his

fellow-countryman Arrian. The history of Rome, which consisted of

eighty books,--and, after the example of Livy, was divided into

decades,--began with the landing of Aeneas in Italy, and was continued

as far as the reign of Alexander Severus (222-235). Of this great work

we possess books 36-60, containing the history of events from 68

B.C.-A.D. 47; books 36 and 55-60 are imperfect. We also have part of 35

and 36-80 in the epitome of John Xiphilinus, an 11th-century Byzantine

monk. For the earlier period the loss of Dio's work is partly supplied

by the history of Zonaras, who followed him closely. Numerous fragments

are also contained in the excerpts of Constantine Porphyrogenitus. Dio's

work is a most important authority for the history of the last years of

the republic and the early empire. His industry was great and the

various important offices he held afforded him ample opportunities for

historical investigation. His style, though marred by Latinisms, is

clearer than that of his model Thucydides, and his narrative shows the

hand of the practised soldier and politician; the language is correct

and free from affectation. But he displays a superstitious regard for

miracles and prophecies; he has nothing to say against the arbitrary

acts of the emperors, which he seems to take as a matter of course; and

his work, although far more than a mere compilation, is not remarkable

for impartiality, vigour of judgment or critical historical faculty.

DIOCESE (formed on Fr. _diocese_, in place of the Eng. form

_diocess_--current until the 19th century--from Lat. _dioecesis_, med.

Lat. variant _diocesis_, from Gr. [Greek: dioikesis], "housekeeping,"

"administration," [Greek: dioikein], "to keep house," "to govern"), the

sphere of a bishop's jurisdiction. In this, its sole modern sense, the

word diocese (_dioecesis_) has only been regularly used since the 9th

century, though isolated instances of such use occur so early as the

3rd, what is now known as a diocese having been till then usually called

a _parochia_ (parish). The Greek word [Greek: dioikesis], from meaning

"administration," came to be applied to the territorial circumscription

in which administration was exercised. It was thus first applied e.g. to

the three districts of Cibyra, Apamea and Synnada, which were added to

Cilicia in Cicero's time (between 56 and 50 B.C.). The word is here

equivalent to "assize-districts" (Tyrrell and Purser's edition of Cicero

_Epist. ad fam._ iii. 8. 4; xiii. 67; cf. Strabo xiii. 628-629). But in

the reorganization of the empire, begun by Diocletian and completed by

Constantine, the word "diocese" acquired a more important meaning, the

empire being divided into twelve dioceses, of which the

largest--Oriens--embraced sixteen provinces, and the

smallest--Britain--four (see ROME: _Ancient History_; and W. T. Arnold,

_Roman Provincial Administration_, pp. 187, 194-196, which gives a list

of the dioceses and their subdivisions). The organization of the

Christian church in the Roman empire following very closely the lines of

the civil administration (see CHURCH HISTORY), the word diocese, in its

ecclesiastical sense, was at first applied to the sphere of

jurisdiction, not of a bishop, but of a metropolitan.[1] Thus Anastasius

Bibliothecarius (d. c. 886), in his life of Pope Dionysius, says that he

assigned churches to the presbyters, and established dioceses

(_parochiae_) and provinces (_dioeceses_). The word, however, survived

in its general sense of "office" or "administration," and it was even

used during the middle ages for "parish" (see Du Cange, _Glossarium_, s.

"Dioecesis" 2).

The practice, under the Roman empire, of making the areas of

ecclesiastical administration very exactly coincide with those of the

civil administration, was continued in the organization of the church

beyond the borders of the empire, and many dioceses to this day preserve

the limits of long vanished political divisions. The process is well

illustrated in the case of English bishoprics. But this practice was

based on convenience, not principle; and the limits of the dioceses,

once fixed, did not usually change with the changing political

boundaries. Thus Hincmar, archbishop of Reims, complains that not only

his metropolitanate (_dioecesis_) but his bishopric (_parochia_) is

divided between two realms under two kings; and this inconvenient

overlapping of jurisdictions remained, in fact, very common in Europe

until the readjustments of national boundaries by the territorial

settlements of the 19th century. In principle, however, the subdivision

of a diocese, in the event of the work becoming too heavy for one

bishop, was very early admitted, e.g. by the first council at Lugo in

Spain (569), which erected Lugo into a metropolitanate, the consequent

division of diocese being confirmed by the king of the second council,

held in 572. Another reason for dividing a diocese, and establishing a

new see, has been recognized by the church as duly existing "if the

sovereign should think fit to endow some principal village or town with

the rank and privileges of a city" (Bingham, lib. xvii. c. 5). But there

are canons for the punishment of such as might induce the sovereign so

to erect any town into a city, solely with the view of becoming bishop

thereof. Nor could any diocese be divided without the consent of the

primate.

In England an act of parliament is necessary for the creation of new

dioceses. In the reign of Henry VIII. six new dioceses were thus created

(under an act of 1539); but from that time onward until the 19th century

they remained practically unchanged. The Ecclesiastical Commissioners

Act 1836, which created two new dioceses (Ripon and Manchester),

remodelled the state of the old dioceses by an entirely new adjustment

of the revenues and patronage of each see, and also extended or

curtailed the parishes and counties in the various jurisdictions.

By the ancient custom of the church the bishop takes his title, not from

his diocese, but from his see, i.e. the place where his cathedral is

established. Thus the old episcopal titles are all derived from cities.

This tradition has been broken, however, by the modern practice of

bishops in the United States and the British colonies, e.g. archbishop

of the West Indies, bishop of Pennsylvania, Wyoming, &c. (see BISHOP).
