The forms adopted in the royal chanceries were naturally imitated in the

composition of private deeds which in all countries form the mass of

material for historical and diplomatic research. The student of English

diplomatic will soon remark how readily the private charters, especially

conveyances of real property, fall into classes, and how stereotyped the

phraseology and formulae of each class become, only modified from time

to time by particular acts of legislation. The brevity of the early

conveyances is maintained through successive generations, with only

moderate growth as time progresses through the 12th, 13th and 14th

centuries. The different kinds of deeds which the requirements of

society have from time to time called into existence must be learned by

the student from the text-books. But a particular form of document which

was especially in favour in England should be mentioned. This was the

chirograph (Gr. [Greek: cheir], a hand, [Greek: graphein], to write),

which is found even in the Anglo-Saxon period, and which got its name

from the word _chirographum_, _cirographum_ or _cyrographum_ being

written in large letters at the head of the deed. At first the word was

written, presumably, at the head of each of the two authentic copies

which the two parties to a transaction would require. Then it became the

habit to use the word thus written as a tally, the two copies of the

deed being written on one sheet, head to head, with the word between

them, which was then cut through longitudinally in a straight, or more

commonly waved or indented (_in modum dentium_) line, each of the two

copies thus having half of the word at the head. Any other word, or a

series of letters, might thus be employed; and more than two copies of a

deed could thus be made to tally. The chirograph was the precursor of

the modern indenture, the commonest form of English deeds, though no

longer a tally. In other countries, the notarial instrument has

performed the functions which the chirograph and indenture have

discharged for us.

DIPOENUS and SCYLLIS, early Greek sculptors, who worked together, and

are said to have been pupils of Daedalus. Pliny assigns to them the date

580 B.C., and says that they worked at Sicyon, which city from their

time onwards became one of the great schools of sculpture. They also

made statues for Cleonae and Argos. They worked in wood, ebony and

ivory, and apparently also in marble. It is curious that no inscription

bearing their names has come to light.

DIPPEL, JOHANN KONRAD (1673-1734), German theologian and alchemist, son

of a Lutheran pastor, was born at the castle of Frankenstein, near

Darmstadt, on the 10th of August 1673. He studied theology at Giessen.

After a short visit to Wittenberg he went to Strassburg, where he

lectured on alchemy and chiromancy, and occasionally preached. He gained

considerable popularity, but was obliged after a time to quit the city,

owing to his irregular manner of living. He had up to this time espoused

the cause of the orthodox as against the pietists; but in his two first

works, published under the name "Christianus Democritus," _Orthodoxia

Orthodoxorum_ (1697) and _Papismus vapulans Protestantium_ (1698), he

assailed the fundamental positions of the Lutheran theology. He held

that religion consisted not in dogma but exclusively in love and

self-sacrifice. To avoid persecution he was compelled to wander from

place to place in Germany, Holland, Denmark and Sweden. He took the

degree of doctor of medicine at Leiden in 1711. He discovered Prussian

blue, and by the destructive distillation of bones prepared the

evil-smelling product known as Dippel's animal oil. He died near

Berleburg on the 25th of April 1734.

An enlarged edition of Dippel's collected works was published at

Berleburg in 1743. See the biographies by J. C. G. Ackermann (Leipzig,

1781), H. V. Hoffmann (Darmstadt, 1783), K. Henning (1881) and W.

Bender (Bonn, 1882); also a memoir by K. Bucher in the _Historisches

Taschenbuch_ for 1858.

DIPSOMANIA (from [Gr. dipsa], thirst, and [Greek: mania], madness), a

term formerly applied to the attacks of delirium (q.v.) caused by

alcoholic poisoning. It is now sometimes loosely used as equivalent to

the condition of incurable inebriates, but strictly should be confined

to the pathological and insatiable desire for alcohol, sometimes

occurring in paroxysms.

DIPTERA ([Greek: dis], double, [Greek: ptera], wings), a term (first

employed in its modern sense by Linnaeus, _Fauna Suecica_, 1st ed.,

1746, p. 306) used in zoological classification for one of the Orders

into which the _Hexapoda_, or Insecta, are divided. The relation of the

Diptera (two-winged flies, or flies proper) to the other Orders is dealt

with under Hexapoda (q.v.).

The chief characteristic of the Diptera is expressed in the name of the

Order, since, with the exception of certain aberrant and apterous forms,

flies possess but a single pair of membranous wings, which are attached

to the meso-thorax. Wing-covers and hind-wings are alike absent, and the

latter are represented by a pair of little knobbed organs, the halteres

or balancers, which have a controlling and directing function in flight.

The other structural characters of the Order may be briefly summarized

as:--mouth-parts adapted for piercing and sucking, or for suction alone,

and consisting of a proboscis formed of the labium, and enclosing

modifications of the other usual parts of the mouth, some of which,

however, may be wanting; a thorax fused into a single mass; and legs

with five-jointed tarsi. The wings, which are not capable of being

folded, are usually transparent, but occasionally pigmented and adorned

with coloured spots, blotches or bands; the wing-membrane, though

sometimes clothed with minute hairs, seldom bears scales; the

wing-veins, which are of great importance in the classification of

Diptera, are usually few in number and chiefly longitudinal, there being

a marked paucity of cross-veins. In a large number of Diptera an

incision in the posterior margin of the wing, near the base, marks off a

small lobe, the posterior lobe or alula, while connected with this but

situated on the thorax itself there is a pair of membranous scales, or

squamae, which when present serve to conceal the halteres. The antennae

of Diptera, which are also extremely important in classification, are

thread-like in the more primitive families, such as the _Tipulidae_

(daddy-long-legs), where they consist of a considerable number of

joints, all of which except the first two, and sometimes also the last

two, are similar in shape; in the more specialized families, such as the

_Tabanidae_ (horse-flies), _Syrphidae_ (hover-flies) or _Muscidae_

(house-flies, blue-bottles and their allies), the number of antennal

joints is greatly reduced by coalescence, so that the antennae appear to

consist of only three joints. In these forms, however, the third joint

is really a complex, which in many families bears in addition a jointed

bristle (arista) or style, representing the terminal joints of the

primitive antenna. Although in the case of the majority of Diptera the

body is more or less clothed with hair, the hairy covering is usually so

short that to the unaided eye the insects appear almost bare; some

forms, however, such as the bee-flies (_Bombylius_) and certain

robber-flies (_Asilidae_) are conspicuously hairy. Bristles are usually

present on the legs, and in the case of many families on the body also;

those on the head and thorax are of great importance in classification.

Between 40,000 and 50,000 species of Diptera are at present known, but

these are only a fraction of those actually in existence. The species

recognized as British number some 2700, but to this total additions are

constantly being made. As a rule flies are of small or moderate size,

and many, such as certain blood-sucking midges of the genus

_Ceratopogon_, are even minute; as extremes of size may be mentioned a

common British midge, _Ceratopogon varius_, the female of which measures

only 1-1/4 millimetre, and the gigantic _Mydaidae_ of Central and South

America as well as certain Australian robber-flies, which have a body

1-3/4 in. long, with a wing-expanse of 3-1/4 in. In bodily form Diptera

present two main types, either, as in the case of the more primitive and

generalized families, they are gnat- or midge-like in shape, with

slender bodies and long, delicate legs, or else they exhibit a more or

less distinct resemblance to the common house-fly, having compact and

stoutly built bodies and legs of moderate length. Diptera in general are

not remarkable for brilliancy of coloration; as a rule they are dull and

inconspicuous in hue, the prevailing body-tints being browns and greys;

occasionally, however, more especially in species (_Syrphidae_) that

mimic Hymenoptera, the body is conspicuously banded with yellow; a few

are metallic, such as the species of _Formosia_, found in the islands of

the East Indian Archipelago, which are among the most brilliant of all

insects. The sexes in Diptera are usually alike, though in a number of

families with short antennae the males are distinguished by the fact

that their eyes meet together (or nearly so) on the forehead.

Metamorphosis in Diptera is complete; the larvae are utterly different

from the perfect insects in appearance, and, although varying greatly in

outward form, are usually footless grubs; those of the _Muscidae_ are

generally known as maggots. The pupa either shows the appendages of the

perfect insect, though these are encased in a sheath and adherent to the

body, or else it is entirely concealed within the hardened and

contracted larval integument, which forms a barrel-shaped protecting

capsule or puparium.

Diptera are divided into some sixty families, the exact classification

of which has not yet been finally settled. The majority of authors,

however, follow Brauer in dividing the order into two sections,

Orthorrhapha and Cyclorrhapha, according to the manner in which the

pupa-case splits to admit of the escape of the perfect insect. The

general characteristics of the pupae in these two sections have already

been described.

In the Orthorrhapha, in the pupae of which the appendages of the perfect

insect are usually visible, the pupa-case generally splits in a straight

line down the back near the cephalic end; in front of this longitudinal

cleft there may be a small transverse one, the two together forming a

T-shaped fissure. In the Cyclorrhapha on the other hand, in which the

actual pupa is concealed within the hardened larval skin, the imago

escapes through a circular orifice formed by pushing off or through the

head end of the puparium. The Diptera Orthorrhapha include the more

primitive and less specialized families such as the _Tipulidae_

(daddy-long-legs), _Culicidae_ (gnats or mosquitoes), _Chironomidae_

(midges), _Mycetophilidae_ (fungus-midges), _Tabanidae_ (horse-flies),

_Asilidae_ (robber-flies), &c. The Diptera Cyclorrhapha on the other

hand consist of the most highly specialized families, such as the

_Syrphidae_ (hover-flies), _Oestridae_ (bot and warble flies), and

_Muscidae_ (_sensu latiore_--the house-fly and its allies, including

tsetse-flies, flesh-flies, _Tachininae_, or flies the larvae of which

are internal parasites of caterpillars, &c). It is customary to divide

the Orthorrhapha into the two divisions Nematocera and Brachycera, in

the former of which the antennae are elongate and in a more or less

primitive condition, as described above, while in the latter these

organs are short, and, as already explained, apparently composed of only

three joints.

Within the divisions named--Orthorrhapha Nematocera, Orthorrhapha

Brachycera and Cyclorrhapha--the constituent families are usually

grouped into a series of "superfamilies," distinguished by features of

structure or habit. Certain extremely aberrant Diptera, which, in

consequence of the adoption of a parasitic mode of life, have undergone

great structural modification, are further remarkable for their peculiar

mode of reproduction, on account of which the families composing the

group are often termed Pupipara. In these forms the pregnant female,

instead of laying eggs, as Diptera usually do, or even producing a

number of minute living larvae, gives birth at one time but to a single

larva, which is retained within the oviduct of the mother until adult,

and assumes the pupal state immediately on extrusion. The Pupipara are

also termed Eproboscidea (although they actually possess a

well-developed and functional proboscis), and by some dipterists the

Eproboscidea are regarded as a suborder and contrasted as such with the

rest of the Diptera, which are styled the suborder Proboscidea. By other

writers Proboscidea and Eproboscidea are treated as primary divisions of

the Cyclorrhapha. In reality, however, the families designated

Eproboscidea (_Hippoboscidae_, _Braulidae_, _Nycteribiidae_ and

_Streblidae_), are not entitled to be considered as constituting either

a suborder, or even a main division of the Cyclorrhapha; they are simply

Cyclorrhapha much modified owing to parasitism, and in view of the

closely similar mode of reproduction in the tsetse-flies the special

designation Pupipara should be abandoned. Before leaving the subject of

classification it may be noted in passing that in 1906 Professor

Lameere, of Brussels, proposed a scheme for the classification of

Diptera which as regards both the limits of the families and their

grouping into higher categories differs considerably from that in

current use.

Little light on the relationship and evolution of the various families

of Diptera is afforded by fossil forms, since as a rule the latter are

readily referable to existing families. With the exception of a few

species from the Solenhofen lithographic Oolite, fossil Diptera belong

to the Tertiary Period, during which the members of this order attained

a high degree of development. In amber, as proved by the deposits on the

shores of the Baltic, the proverbial "fly" is more numerous than any

other creatures, and with very few exceptions representatives of all the

existing families have been found. The famous Tertiary beds at

Florissant, Colorado, have yielded a considerable number of remarkably

well-preserved _Tipulidae_ (in which family are included the most

primitive of existing Diptera), as also species belonging to other

families, such as _Mycetophilidae_ and even _Oestridae_.

Diptera as an order are probably more widely distributed over the

earth's surface than are the representatives of any similar division of

the animal kingdom. Flies seem capable of adapting themselves to

extremes of cold equally as well as to those of heat, and species

belonging to the order are almost invariably included in the collections

brought back by members of Arctic expeditions. Others are met with in

the most isolated localities; thus the Rev. A. E. Eaton discovered on

the desolate shores of Kerguelen's Island apterous and semi-apterous

Diptera (_Tipulidae_ and _Ephydridae_) of a degraded type adapted to the

climatic peculiarities of the locality. Many bird parasites belonging to

the _Hippoboscidae_ have naturally been carried about the world by their

hosts, while other species, such as the house-fly, blow-fly and

drone-fly, have in like manner been disseminated by human agency. Most

families and a large proportion of genera are represented throughout the

world, but in some cases (e.g. _Glossina_--see TSETSE-FLY) the

distribution of a genus is limited to a continent. As a rule the general

_facies_ as well as dimensions are remarkably uniform throughout a

family, so that tropical species often differ little in appearance from

those inhabiting temperate regions. Many instances of exaggerated and

apparently unnatural structure nevertheless occur, as in the case of the

genera _Pangonia_, _Nemestrina_, _Achias_, _Diopsis_ and the family

_Celyphidae_, and, as might be expected, it is chiefly in tropical

species that these peculiarities are found. To a geographical

distribution of the widest extent, Diptera add a range of habits of the

most diversified nature; they are both animal and vegetable feeders, an

enormous number of species acting, especially in the larval state, as

scavengers in consuming putrescent or decomposing matter of both kinds.

The phytophagous species are attached to various parts of plants, dead

or alive; and the carnivorous in like manner feed on dead or living

flesh, or its products, many larvae being parasitic on living animals of

various classes (in Australia the larva of a species of _Muscidae_ is

even a parasite of frogs), especially the caterpillars of Lepidoptera,

which are destroyed in great numbers by _Tachininae_. The recent

discovery of a bloodsucking maggot, which is found in native huts

throughout the greater part of tropical and subtropical Africa, and

attacks the inmates when asleep, is of great interest.

It may confidently be asserted that, of insects which directly or

indirectly affect the welfare of man, Diptera form the vast majority,

and it is a moot point whether the good effected by many species in the

rapid clearing away of animal and vegetable impurities, and in keeping

other insect enemies in check, counterbalances the evil and annoyance

wrought by a large section of the Order. The part played by certain

blood-sucking Diptera in the dissemination of disease is now well known

(see MOSQUITO and TSETSE-FLY), and under the term _myiasis_ medical

literature includes a lengthy recital of instances of the presence of

Dipterous larvae in various parts of the living human body, and the

injuries caused thereby. That Diptera of the type of the common

house-fly are often in large measure responsible for the spread of such

diseases as cholera and enteric fever is undeniable, and as regards

blood-sucking forms, in addition to those to which reference has already

been made, it is sufficient to mention the vast army of pests

constituted by the midges, sand-flies, horse-flies, &c., from the

attacks of which domestic animals suffer equally with man, in addition

to being frequently infested with the larvae of the bot and warble flies

(_Gastrophilus_, _Oestrus_ and _Hypoderma_). Lastly, as regards the

phytophagous forms, there can be no doubt that the destruction of

grass-lands by "leather-jackets" (the larvae of crane-flies, or

daddy-long-legs,--_Tipula oleracea_ and _T. paludosa_), of divers fruits

by _Ceratitis capitata_ and species of _Dacus_, and of wheat and other

crops by the Hessian-fly (_Mayetiola destructor_) and species of

_Oscinis_, _Chlorops_, &c., is of very serious consequence.

With many writers it is customary to treat the fleas as a sub-order of

Diptera, under the title Aphaniptera or Siphonaptera. Since, however,

although undoubtedly allied to the Diptera, they must have diverged from

the ancestral stem at an early period, before the existing forms of

Diptera became so extremely specialized, it seems better to regard the

fleas as constituting an independent order (see FLEA). (E. E. A.)

DIPTERAL (Gr. for "double-winged"), the architectural term applied to

those temples which have a double range of columns in the peristyle, as

in the temple of Diana at Ephesus.

DIPTYCH (Gr. [Greek: diptychos], two-folding), (1) A tablet made with a

hinge to open and shut, used in the Roman empire for letters (especially

love-letters), and official tokens of the commencement of a consul's,

praetor's or aedile's term of office. The latter variety of diptych was

inscribed with the magistrate's name and bore his portrait, and was

issued to his friends and the public generally. They were made of

boxwood or maple. More costly examples were in cedar, ivory (q.v.),

silver or sometimes gold. They were often sent as New Year gifts.

(2)In the primitive church when the worshippers brought their own

offerings of bread and wine, from which were taken the Communion

elements, the names of the contributors were recorded on diptychs and

read aloud. To these names were early added those of deceased members of

the community whom it was desired to commemorate. This custom rapidly

developed into a kind of commemoration of saints and benefactors, living

and dead; especially, in each church, were the names of those who had

been its bishops recorded. The custom was maintained until the lists

became so long that it was impossible to read them through, and the

observance in this form had to be abandoned. The insertion of a name on

the diptych, thereby securing the prayers of the church, was a privilege

from which a person could be excluded on account of suspicion of heresy

or by the intrigues of enemies. His name could, if written, be expunged

under similar circumstances. The names thus written were read from the

ambo, in which the diptych was kept. The reading of these names during

the canon of the mass gave rise to the term _canonization_. By various

councils it was ordained that the name of the pope should always be

inserted in the diptych list.

The addition of _dates_ resulted from the custom of recording baptisms

and deaths; and thus the diptych developed into a calendar and formed

the germ of the elaborate system of festologies, martyrologies and

calendars which developed in the church.

The diptych went by various names in the early church--mystical tablets,

anniversary books, ecclesiastical matriculation registers or books of

the living. According to the names inscribed, bishops, the dead or the

living, a diptych might be a _diptycha episcoporum_, _diptycha

mortuorum_ or _diptycha vivorum_.

In course of time the list of the names swelled to such proportions that

the space afforded by the diptych was insufficient. A third fold was

consequently provided, and the tablet became a _triptych_ (though the

name _diptych_ was retained as a general term for the object). Further

room was afforded by the insertion of leaves of parchment or wood

between the folds. The custom of reading names from the diptychs died

out about the 8th century. The diptychs, however, were retained as altar

ornaments. From the original consular documents onwards, the outsides of

the folds had always been richly ornamented, and when they ceased to be

of immediate practical use they became merely decorative. Instead of the

list of names the inside was ornamented like the outer, and in the

middle ages the best painters of the day would often paint them. When

folded, the portraits of the donor and his wife might be shown; when

open there would be three paintings, one on each fold, of a religious

character. (R. A. S. M.)

DIR, an independent state in the North-West Frontier Province of India,

lying to the north-east of Swat. Its importance chiefly arises from the

fact that it commands the greater part of the route between Chitral and

the Peshawar frontier. The quarrels and intrigues between the khan of

Dir and Umra Khan of Jandol were among the chief events that led up to

the Chitral Campaign of 1895. During that expedition the khan made an

agreement with the British Government to keep the road to Chitral open

in return for a subsidy. Including the Bashkars, an aboriginal tribe

allied to the Torwals and Garhuis, who inhabit Panjkora Kohistan, the

population is estimated at about 100,000.

DIRCE, in Greek legend, daughter of Helios the sun-god, the second wife

of Lycus, king of Thebes. She sorely persecuted Antiope, his first wife,

who escaped to Mount Cithaeron, where her twin sons Amphion and Zethus

were being brought up by a herdsman who was ignorant of their parentage.

Having recognized their mother, the sons avenged her by tying Dirce to

the horns of a wild bull, which dragged her about till she died. Her

body was cast into a spring near Thebes, which was ever afterwards

called by her name. Her punishment is the subject of the famous group

called "The Farnese Bull," by Apollonius and Tauriscus of Tralles, in

the Naples museum (see GREEK ART, Plate I. fig. 51).

DIRECT MOTION, in astronomy, the apparent motion of a body of the solar

system on the celestial sphere in the direction from west to east; so

called because this is the usual direction of revolution and rotation of

the heavenly bodies.

DIRECTORS, in company law, the agents by whom a trading or public

company acts, the company itself being a legal abstraction and unable to

do anything. As joint-stock companies have multiplied and their

enterprise has extended, the position of directors has become one of

increasing influence and importance. It is they who control the colossal

funds now invested in trading companies, and who direct their policy

(for shareholders are seldom more than dividend-drawers). Upon their

uprightness, vigilance and sound judgment depends the welfare of the

greatest part of the trade of the country concerned. It is not to be

wondered at that in view of this influence and independence of action

the law courts have held directors to a strict standard of duty, and

that the parliament of the United Kingdom has singled out directors from

other agents for special legislation in the Directors Liability Act

1890, the Larceny Act 1861, the Companies Act 1867 and the Winding-up

Act 1890.

The first directors of a company are generally appointed by the articles

of association. Their consent to act must now, under the Companies Act

1908, be filed with the registrar of joint-stock companies. Directors

other than the first are elected at the annual general meeting, a

certain proportion of the acting directors--usually one-third--retiring

under the articles by rotation each year, and their places being filled

up by election. A share qualification is nearly always required, on the

well-recognized principle that a substantial stake in the undertaking is

the best guarantee of fidelity to the company's interests. A director

once appointed cannot be removed during his term of office by the

shareholders, unless there is a special provision for that purpose in

the articles of association; but a company may dismiss a director if the

articles--as is usually the case--authorize dismissal. The authority and

powers of directors are prima facie those necessary for carrying on the

ordinary business of the company, but it is usual to define the more

important of such powers in the articles of association. For instance,

it is commonly prescribed how and when the directors may make calls, to

what amount they may borrow, how they may invest the funds of the

company, in what circumstances they may forfeit shares, or veto

transfers, in what manner they shall conduct their proceedings, and what

shall constitute a quorum of the board. Whenever, indeed, specific

directions are desirable they may properly be given by the articles. But

superadded to and supplementing these specific powers there is usually

inserted in the articles a general power of management in terms similar

to those of clause 55 of the model regulations for a company, known as

Table A (clause 71 of the revised Table). The powers, whether general or

specific, thus confided to directors are in the nature of a trust, and

the directors must exercise them with a single eye to the benefit of the

company. For instance, in allotting shares they must consult the

interests of the company, not favour their friends. So in forfeiting

shares they must not use the power collusively for the purpose of

relieving the shareholder from liability. To do so is an abuse of the

power and a fraud on the other shareholders.

It would give a very erroneous idea of the position and functions of

directors to speak of them--as is sometimes done--as trustees. They are

only trustees in the sense that every agent is. They are "commercial men

managing a trading concern for the benefit of themselves and the other

shareholders." They have to carry on the company's business, to extend

and consolidate it, and to do this they must have a free hand and a

large discretion to deal with the exigencies of the commercial

situation. This large discretion the law allows them so long as they

keep within the limits set by the company's memorandum and articles.

They are not to be held liable for mere errors of judgment, still less

for being defrauded. That would make their position intolerable. All

that the law requires of them is that they should be faithful to their

duties as agents--"diligent and honest," to use the words of Sir George

Jessel, formerly master of the rolls. Thus in the matter of diligence it

is a director's duty to attend as far as possible all meetings of the

board; at the same time non-attendance, unless gross, will not amount to

negligence such as to render a director liable for irregularities

committed by his co-directors in his absence. A director again must not

sign cheques without informing himself of the purpose for which they are

given. A director, on the same principle, must not delegate his duties

to others unless expressly authorized to do so, as where the company's

articles empower the directors to appoint a committee. Directors may, it

is true, employ skilled persons, such as engineers, valuers or

accountants, to assist them, but they must still exercise their judgment

as business men on the materials before them. Then in the matter of

honesty, a director must not accept a present in cash or shares or in

any other form whatever from the company's vendor, because such a

present is neither more nor less than a bribe to betray the interests of

the company, nor must he make any profit in the matter of his agency

without the knowledge and consent of his principal, the company. He must

not, in other words, put himself in a position in which his duty to the

company and his own interest conflict or even may conflict. This rule

often comes into play in the case of contracts between a company and a

director. There is nothing in itself invalid in such a contract, but the

onus is on the director if he would keep such a contract to show that

the company assented to his making a profit out of the contract, and for

that purpose he must show that he made full and fair disclosure to the

company of the nature and extent of his interest under the contract. It

is for this reason that when a company's vendor is also a director he

does not join the board until his co-directors have exercised an

independent judgment on the propriety of the purchase.

A director must also bear in mind--what is a fundamental principle of

company management--that the funds of the company are entrusted to the

directors for the objects of the company as defined by the company's

memorandum of association and authorized by the general law, and that

they must not be diverted from those objects or applied to purposes

which are outside the objects of the company, _ultra vires_, as it is

commonly called, or outside the powers of management given by the

shareholders to the directors. This does not abridge the large

discretion allowed to directors in carrying on the business of the

company. The funds embarked in a trading company are intended to be

employed for the acquisition of gain, and risk, greater or less

according to circumstances, is necessarily incidental to such

employment; but it is quite another matter when directors pay dividends

out of capital, or return capital to the shareholders, or spend money of

the company in "rigging" the market, or in buying the company's shares

or paying commission for underwriting the shares of the company except

where such commission is authorized under acts of 1900 and 1907,

incorporated in the Companies Act 1908. Directors who in these or any

other ways misapply the funds of the company are guilty of what is

technically known as "misfeasance" or breach of trust, and all who join

in the misapplication are jointly and severally liable to replace the

sums so misapplied. The remedy of the company for misfeasance, if the

company is a going concern, is by action against the delinquent

directors; but where a company is being wound up, the legislature has,

under the Winding-up Act 1890, provided a summary mode of proceeding, by

which the official receiver or liquidator, or any creditor or

contributory of the company, may take out what is known as a misfeasance

summons, to compel the delinquent director or officer to repay the

misapplied moneys or make compensation. The departmental committee of

the Board of Trade in its report (July 1906) recommended that the court

should be given a discretionary power, analogous to that it already

possesses in the case of trustees under the Judicial Trustees Act 1896,

s. 3, to relieve a director (or a promoter) in certain cases from

liability. This recommendation has been given effect to by s. 279 of the

Companies Act 1908, which provides that, "If in any proceeding against a

director of a company for negligence or breach of trust it appears to a

court that the director is or may be liable in respect of the negligence

or breach of trust, but has acted honestly and reasonably and ought

fairly to be excused for the negligence or breach of trust, the court

may relieve him either wholly or partly from his liability on such terms

as the court may think proper."

Directors who circulate a prospectus containing statements which they

know to be false, with intent to induce any person to become a

shareholder, may be prosecuted under S 84 of the Larceny Act 1861. They

are also liable criminally for falsification of the company's books, and

for this or any other criminal offence the court in winding up may, on

the application of the liquidator, direct a prosecution. As to the

liability of directors for statements or omissions in a prospectus see

COMPANY.

In managing the affairs of the company directors must meet together and

act as a body, for the company is entitled to their collective wisdom in

council assembled. Board meetings are held at such intervals as the

directors think expedient. Notice of the meeting must be given to all

directors who are within reach, but the notice need not specify the

particular business to be transacted. The articles usually fix, or give

the directors power to fix, what number shall constitute a quorum for a

board meeting. They also empower the directors to elect a chairman of

the board. The directors exercise their powers by a resolution of the

board which is recorded in the directors' minute-book.

The court will not as a rule interfere with the discretion of directors

honestly exercised in the management of the affairs of the company. The

directors have prima facie the confidence of the shareholders, and it is

not for the court to say that such confidence is misplaced. If the

stockholders are dissatisfied with the management the remedy is in their

own hands--they can call a meeting and elect a new board.

A company's articles usually provide for the payment of a certain sum to

each director for his services during the year. When this is the case it

is an authority to the directors to pay themselves the amount of such

remuneration. The remuneration, unless otherwise expressly provided,

covers all expenses incidental to the directors' duties. A director, for

instance, cannot claim to be paid in addition to his fixed remuneration

his travelling expenses for attending board meetings.

When a company winds up, the directors' powers of management come to an

end. Their agency is superseded in favour of that of the liquidator.

(E. MA.)

DIRECTORY, a term meaning literally that which guides or directs, and so

applied to a book or set of rules giving directions for public worship.

The _directorium_ or _ordo_ of the Roman Church contains regulations as

to the Mass and office to be used on each day throughout the year, and

the word is found in the _Directory for the Publick Worship of God_

drawn up in 1644 at the Westminster Assembly. The term now usually

signifies a book containing the names, addresses and occupations, &c. of

the inhabitants of a town or district, or of a similar list of the users

of a telephone supply, or of the members of a particular profession or

trade. The name _Directoire_ or Directory was given to the body which

held the executive power in France from October 1795 until November 1799

(see FRENCH REVOLUTION).

DIRGE, a song or hymn of mourning, particularly one sung at funerals or

at a Service in commemoration of the dead. It is derived from the first

word of the antiphon _"Dirige, Domine, Deus meus, in conspectu tuo viam

meam"_ (Guide, O Lord, my God, my way in Thy sight), of the opening

psalm in the office for the dead in the Roman Church. The antiphon is

adapted from verse 8 of Psalm v.

DIRK, a dagger, particularly the heavy dagger carried by the Highlanders

of Scotland. The dirk as worn in full Highland costume is an elaborately

ornamented weapon, with cairngorms or other stones set in the head of

the handle, which has no guard. Inserted in the sheath there may be two

small knives. The dirk, in the shape of a straight blade, with a small

guard, some 18 in. long, is worn by midshipmen in the British navy. The

origin of the word is doubtful. The earlier forms were _dork_ and

_durk_, and the spelling _dirk_, adopted by Johnson, represents the

pronunciation of the second form. The name seems to have been early

applied to the daggers of the Highlanders, but the Gaelic word is

_biodag_, and the Irish _duirc_, often stated to be the origin, is only

an adaptation of the English word. It may be a corruption of the German

_Dolch_, a dagger. The suggestion that it is an application of the

Christian name "Dirk," the short form of "Dieterich," is not borne out,

according to the _New English Dictionary_, by any use of this name for a

dagger, and is further disproved by the earlier English spelling.

DIRSCHAU, a town of Germany, in the kingdom of Prussia, province of West

Prussia, on the left bank of the Vistula, 20 m. S. from Danzig and at

the junction of the important lines of railway Berlin-Konigsberg and

Danzig-Bromberg. Pop. (1905) 14,185. It has a Roman Catholic and a

Protestant church and several schools. The river is here crossed by two

fine iron bridges. The older structure dating from the year 1857,

originally used for the railway, is now given up to road traffic, and

the railway carried by a new bridge completed in 1891. Dirschau has

railway workshops and manufactories of sugar, agricultural implements

and cement. During the war with Poland, Gustavus Adolphus made it his

headquarters for many months after its capture in 1626.

DISABILITY, a term meaning, in general, want of ability, and used in law

to denote an incapacity in certain persons or classes of persons for the

full enjoyment of duties or privileges, which, but for their

disqualification, would be open to them; hence, legal disqualification.

Thus, married women, persons under age, insane persons, convicted felons

are under disability to do certain legal acts. This disability may be

absolute, wholly disabling the person so long as it continues, or

partial, ceasing on discontinuation of the disabling state, as

attainment of full age.

DISCHARGE (adapted from the O. Fr. _descharge_, modern _decharge_, from

a med. Lat. _discargare_, to unload, _dis-_ and _carricare_, to load,

cf. "charge"), a word meaning relief from a load or burden, hence

applied to the unloading of a ship, the firing of a weapon, the passage

of electricity from an electrified body, the issue from a wound, &c.

From the sense of relief from an obligation, "discharge" is also applied

to the release of a soldier or sailor from military or naval service, or

of the crew of a merchant vessel, or to the dismissal from an office or

situation. In law, it is used of a document or other evidence that can

be accepted as proof of the release from an obligation, as of a receipt,

on payment of money due. Similarly it is applied to the release in

accordance with law of a person in custody on a criminal charge, and to

the legal release of a bankrupt from further liability for debts

provable in the bankruptcy except those incurred by fraud or debts to

the crown. It is also applied to the reversal of an order of a court. In

the case of divorce, where the rule _nisi_ is not made absolute, the

rule is said to be discharged.

DISCHARGING ARCH, in architecture, an arch built over a lintel or

architrave to take off the superincumbent weight. The earliest example

is found in the Great Pyramid, over the lintels of the entrance passage

to the tomb: it consisted of two stones only, resting one against the

other. The same object was attained in the Lion Gate and the tomb of

Agamemnon, both in Mycenae, and in other examples in Greece, where the

stones laid in horizontal courses, one projecting over the other, left a

triangular hollow space above the lintel of the door, which was

subsequently filled in by vertical sculptured stone panels. The Romans

frequently employed the discharging arch, and inside the portico of the

Pantheon the architraves have such arches over them. In the Golden

Gateway of the palace of Diocletian at Spalato the discharging arches,

semicircular in form, were adopted as architectural features and

decorated with mouldings. The same is found in the synagogues in

Palestine of the 2nd century; and later, in Byzantine architecture,

these moulded archivolts above an architrave constitute one of the

characteristics of the style. In the early Christian churches in Rome,

where a colonnade divided off the nave and aisles, discharging arches

are turned in the frieze just above the architraves.

DISCIPLE, properly a pupil, scholar (Lat. _discipulus_, from _discere_,

to learn, and root seen in _pupillus_), but chiefly used of the personal

followers of Jesus Christ, including the inner circle of the Apostles

(q.v.).

DISCIPLES OF CHRIST, or CHRISTIANS, an American Protestant denomination,

founded by Thomas Campbell, his son Alexander Campbell (q.v.) and Barton

Warren Stone (1772-1844). Stone had been a Presbyterian minister

prominent in the Kentucky revival of 1801, but had been turned against

sectarianism and ecclesiastical authority because the synod had

condemned Richard McNemar, one of his colleagues in the revival, for

preaching (as Stone himself had done) counter to the Westminster

Confession, on faith and the work of the Holy Spirit in conversion. He

had organized the Springfield Presbytery, but in 1804 with his five

fellow ministers signed "The Last Will and Testament of the Springfield

Presbytery," giving up that name and calling themselves "Christians."

Like Stone, Alexander Campbell had adopted (in 1812) immersion, and,

like him, his two great desires were for Christian unity and the

restoration of the ancient order of things. But the Campbellite

doctrines differed widely from the hyper-Calvinism of the Baptists whom

they had joined in 1813, especially on the points on which Stone had

quarrelled with the Presbyterians; and after various local breaks in

1825-1830, when there were large additions to the Restorationists from

the Baptist ranks, especially under the apostolic fervour and

simplicity of the preaching of Walter Scott (1796-1861), in 1832 the

Reformers were practically all ruled out of the Baptist communion. The

Campbells gradually lost sight of Christian unity, owing to the

unfortunate experience with the Baptists and to the tone taken by those

clergymen who had met them in debates; and for the sake of Christian

union it was peculiarly fortunate that in January 1832 at Lexington,

Kentucky, the followers of the Campbells and those of Stone (who had

stressed union more than primitive Christianity) united. Campbell

objected to the name "Christians" as sectarianized by Stone, but

"Disciples" never drove out of use the name "Christians."

During the Civil War the denomination escaped an actual scission by

following the neutral views of Campbell, who opposed slavery, war and

abolition. In 1849 the American Christian Missionary Society was formed;

it was immediately attacked as a "human innovation," unwarranted by the

New Testament, by literalists led in later years by Benjamin Franklin

(secretary of the missionary society in 1857), who opposed all church

music also. Isaac Errett (1820-1888) was the most prominent leader of

the progressive party, which was considered corrupt and worldly by the

literalists, many of whom, in spite of his efforts, broke off from the

main body, especially in Indiana, Kentucky, Tennessee, Arkansas and

Texas.

The main body appointed in 1890 a standing committee on Christian union;

their aim in this respect is not for absorption, as was clearly shown by

their answer in 1887 to overtures from the Protestant Episcopal Church

regarding Christian unity. The credal position of the Disciples is

simple: great stress is put upon the phrase "the Christ, the Son of the

living God," and upon the recognition by Jesus of this confession as the

foundation of His church; as to baptism, agreement with Baptists is only

as to the mode, immersion; this is considered "the primitive confession

of Christ and a gracious token of salvation," and as being "for the

remission of sins"; the Disciples generally deny the authority over

Christians of the Old Covenant, and Alexander Campbell in particular

held this view so forcibly that he was accused by Baptists of "throwing

away the Old Testament." The Lord's Supper is celebrated every Sunday,

the bread being broken by the communicants. The Disciples are not

Unitarian in fact or tendency, but they urge the use of simple New

Testament phraseology as to the Godhead. Their church government is

congregational.

The growth of the denomination has been greatest in the states along

the Ohio river, whence they have spread throughout the Union. In 1908

there were 6673 ministers and 1,285,123 communicants in the United

States. There are churches in Canada, in Great Britain and in

Australia. Bethany College, at Bethany, West Virginia, was chartered

in 1840, and Alexander Campbell, who had founded it as Buffalo

Seminary, was its president until his death in 1866; other colleges

founded by the sect are: Kentucky University, Lexington, Ky.; Hiram

College, Hiram, Ohio (1850, until 1867 known as Western Reserve

Eclectic Institute); Butler College, Indianapolis, Indiana (1855);

Christian University, Canton, Missouri (1851; coeducational); Eureka

College, in Woodford county, Illinois (1855; coeducational); Union

Christian College, Merom, Ind. (1859); Texas Christian University,

Waco, Texas (1873, founded as Add Ran College at Thorpe's Springs,

removing to Waco in 1895); Drake University, Des Moines, Iowa (1881);

Milligan College, Milligan, Tennessee (1882); Defiance College,

Defiance, O. (1885); Cotner University, Lincoln, Nebraska (1889); Elon

College, Elon, North Carolina (1890); American University, Harriman,

Tenn. (1893); the Virginia Christian College, Lynchburg, Virginia

(1903), and for negroes, the Southern Christian Institute, Edwards,

Mississippi (1877), and the Christian Bible College, Newcastle, Henry

County, Ky. Theological seminaries are the Berkeley Bible Seminary,

Berkeley, California (1896); the Disciples' Divinity House, Chicago,

Ill. (1894); and the Eugene Divinity School, Eugene, Oregon (1895).

"Bible chairs" were established in state universities and elsewhere by

the Disciples,--at the University of Michigan (1893), at the

University of Virginia (1899), at the University of Calcutta (1900)

and at the University of Kansas (1901). The denomination has

publishing houses in Cincinnati, St Louis, Louisville and Nashville.

See Errett Gates's _History of the Disciples of Christ_ (New York,

1905), in "The Story of the Churches" series, and his _Early Relation

and Separation of Baptists and Disciples_ (Chicago, 1904), a

University of Chicago doctoral thesis; and B. B. Tyler's _History of

the Disciples of Christ_ in vol. xii. of "The American Church History

Series" (New York, 1894).

DISCLAIMER, a renunciation, denial or refusal; a disavowal of claims. In

law the term is used more particularly in the following senses:--(1) In

the law of landlord and tenant, the direct repudiation of that relation

by some act on the part of the tenant. A disclaimer may be verbal or

written, but in such case it must be something more than a mere

renunciation of the tenant's title, or it may be an act which is wholly

inconsistent with the existence of such relation, as the setting up by

the tenant of a distinct title either in himself or some third party.

(2) In the law of bankruptcy, where any part of the property of a

bankrupt consists of land of any tenure burdened with onerous covenants,

of stocks or shares in companies, of unprofitable contracts, or of any

property that is unsaleable, or not readily saleable, by reason of its

binding the possessor to the performance of any onerous act, the

trustee, notwithstanding that he has endeavoured to sell or has taken

possession of the property, or exercised any act of ownership in

relation to it, may, subject to certain provisions, by writing signed by

him, at any time within twelve months after the first appointment of a

trustee, "disclaim" the property (see BANKRUPTCY). (3) In the law of

trusts, disclaimer is the refusal or renunciation of the office or

duties of a trustee. It is an undisputed rule that no one is compellable

to undertake a trust, so that as soon as a person knows he has been

appointed a trustee under some instrument, he should determine whether

he will accept the office or not. Disclaimer of trust should be by deed,

as admitting of no ambiguity, but it may be by conveyance to other

accepting trustees, or orally, or by written declaration, or even by

conduct. (4) In the law of patents, disclaimer is the renunciation, by

amendment of specifications, of the portion of an inventor's claim to

protection.

DISCOUNT. (1) A money-market term for the price paid in order to obtain

immediate realization of a bill not yet due. If a bill for L100 due six

months hence is discounted at the rate of 3% per annum, its holder will

obtain L98, 10s. in cash for it. (2) A Stock-Exchange term applied to a

security, not fully paid, which has fallen below its issue price, and so

is said to stand at so much discount. See PREMIUM.

DISCOVERY, in law, the revealing or disclosing of any matter. The

English common law courts were originally unable to compel a litigant

before a trial to disclose the facts and documents on which he relied.

In equity, however, a different rule prevailed, there being an absolute

right to discovery of all material facts on which a case was founded.

Now the practice is regulated by the Rules of the Supreme Court, 1883,

Order 31. Discovery is of two kinds, namely, by interrogatories and by

affidavit of documents, provision being also made for the production and

inspection of documents. Where a party to a suit can make an affidavit

stating that in his belief certain specified documents are or have been

in the possession of some other party, the court may make an order that

such party state on affidavit whether he has or ever had any of those

documents in his possession, or if he has parted with them or what has

become of them. A further application may then be made by notice to the

party who has admitted possession of the documents for production and

inspection. Copies also may be taken of the more important documents.

There is also discovery of facts obtained by means of interrogatories,

i.e. written questions addressed on behalf of one party, before trial,

to the other party, who is bound to answer them in writing upon oath. In

order to prevent needless expense the party seeking discovery must first

secure the cost of it by paying into court a sum of money, generally not

less than five pounds. See also EVIDENCE.

DISCUS (Gr. [Greek: diskos], disk), a circular plate of stone, later of

metal, which was used by the ancient Greeks for throwing to a distance

as a gymnastic exercise. Judging from specimens found by excavators, the

ancient discus was about 8 or 9 in. in diameter and weighed from 4 to 5

lb., although one of bronze, preserved in the British Museum, weighs

over 8 lb. Sometimes a kind of quoit, spherical in form, was used,

through a hole in which a thong was passed to assist the athlete in

throwing it. The sport of throwing the discus was common in the time of

Homer, who mentions it repeatedly. It formed a part of the _pentathlon_,

or quintuple games, in the ancient Olympic Games. Statius, in _Thebais_,

646-721, fully describes the use of the discus. In the British Museum

there is a restored copy of a statue by Myron (see GREEK ART, Plate IV.

fig. 68) of a discus-thrower (_discobolus_) in the act of hurling the

missile; but the investigations of N. E. Norman Gardiner show that a

wrong attitude has been adopted by the restorer.

Throwing the discus was introduced as an event in modern athletics at

the revived Olympic Games, first held at Athens in 1896, and since that

time it has become a recognized event in the athletic championship

meetings of several European nations, as well as in the United States,

where it has become very popular. According to the American rules the

discus must be of a smooth, hard-wood body without finger-holes,

weighted in the centre with lead disks and capped with polished brass

disks, with a steel ring on the outside. Its weight must be 4-1/2 lb.,

its outside diameter 8 in. and its thickness at the centre 2 in. It must

be thrown from a 7-ft. circle, which may not be overstepped in throwing,

and the throw is measured from the spot where the discus first strikes

the ground to the point in the circumference of the circle on a line

between the centre and the point of striking.

DISINFECTANTS, substances employed to neutralize the action of

pathogenic organisms, and prevent the spread of contagious or infectious

disease. The efficiency of any disinfectant is due to its power of

destroying, or of rendering inert, specific poisons or disease germs.

Therefore antiseptic substances generally are to this extent

disinfectants. So also the deodorizers, which act by oxidizing or

otherwise changing the chemical constitution of volatile substances

disseminated in the air, or which prevent noxious exhalations from

organic substances, are in virtue of these properties effective

disinfectants in certain diseases. A knowledge of the value of

disinfectants, and the use of some of the most valuable agents, can be

traced to very remote times; and much of the Levitical law of cleansing,

as well as the origin of numerous heathen ceremonial practices, are

clearly based on a perception of the value of disinfection. The means of

disinfection, and the substances employed, are very numerous, as are the

classes and conditions of disease and contagion they are designed to

meet. Nature, in the oxidizing influence of freely circulating

atmospheric air, in the purifying effect of water, and in the powerful

deodorizing properties of common earth, has provided the most potent

ever-present and acting disinfecting media. Of the artificial

disinfectants employed or available three classes may be

recognized:--1st, volatile or vaporizable substances, which attack

impurities in the air; 2nd, chemical agents, for acting on the diseased

body or on the infectious discharges therefrom; and 3rd, the physical

agencies of heat and cold. In some of these cases the destruction of the

contagium is effected by the formation of new chemical compounds, by

oxidation, deoxidation or other reaction, and in others the conditions

favourable to life are removed or life is destroyed by high temperature.

Among the first class, aerial or gaseous disinfectants, formic aldehyde

has of late years taken foremost place. The vapour is a powerful

disinfectant and deodorant, and for the surface disinfection of rooms,

fulfils all requirements when used in sufficient amount. It acts more

rapidly than equal quantities of sulphurous acid, and it does not affect

colours. It is non-poisonous, though irritating to the eyes and throat.

With the exception of iron and steel it does not attack metals. It can

be obtained in paraform tabloids, and with a specially constructed

spirit lamp disinfection can be carried out by any one. Twenty tabloids

must be employed for every 1000 cubic ft. of space. Disinfection by

sulphurous acid fumes is of great antiquity, and is still in very

general use; for the purpose of destroying vermin it is more powerful

than formic aldehyde. Camphor and some volatile oils have also been

employed as air disinfectants, but their virtues lie chiefly in masking,

not destroying, noxious effluvia. In the 2nd class--non-gaseous

disinfecting compounds--all the numerous antiseptic substances may be

reckoned; but the substances principally employed in practice are

oxidizing agents, as potassium manganates and permanganates, "Condy's

fluid," and solutions of the so-called "chlorides of lime," soda and

potash, with the chlorides of aluminium and zinc, soluble sulphates and

sulphites, solutions of sulphurous acid, and the tar products--carbolic,

cresylic and salicylic acids. Of the physical agents heat and cold, the

latter, though a powerful natural disinfectant, is not practically

available by artificial means; heat is a power chiefly relied on for

purifying and disinfecting clothes, bedding and textile substances

generally. Different degrees of temperature are required for the

destruction of the virus of various diseases; but as clothing, &c., can

be exposed to a heat of about 250 deg. Fahr. without injury, provision is

made for submitting articles to nearly that temperature. For the

thorough disinfection of a sick-room the employment of all three classes

of disinfectants, for purifying the air, for destroying the virus at its

point of origin, and for cleansing clothing, &c., may be required.

DISMAL, an adjective meaning dreary, gloomy, and so a name given to

stretches of swampy land on the east coast of the United States, as the

Dismal Swamp in Virginia and North Carolina. The derivation has been

much discussed. In the early examples of the use the word is a

substantive, especially in the expression "in the dismal," i.e. in the

dismal time or days. Later it became adjectival, especially in

combination with "days." It has been connected with "decimal," med.

Latin _decimalis_, belonging to a tithe or tenth, and thus the "dismal

days" are the unpleasant days connected with the extortion and

oppression of exacting payment of tithes. According to the _New English

Dictionary_, quoting Professor W. W. Skeat, "dismal" is derived, through

an Anglo-Fr. _dis mal_, from the Lat. _dies mali_, evil or unpropitious

days. This Anglo-French expression, explained as _les mal jours_, is

found in a MS. of Rauf de Linham's _Art de Kalender_, 1256. These days

of evil omen were known as _Dies Aegyptiaci_ (Du Cange, _Glossarium_,

s.v.) or Egyptian days, either as having been instituted by Egyptian

astrologers or with reference to the "ten plagues"; so Chaucer, "I trowe

hit was in the dismal, That were the ten woundes of Egipte" (_Book of

the Duchesse_, 1206). There were two such days in each month.

See Skeat, Trans. _Philol. Soc._ (1888), p. 2, and note on the line in

the "Book of the Duchesse," _The Complete Works of Geoffrey Chaucer_,

vol. i. (1894).

DISORDERLY HOUSE, in law, a house in which the conduct of its inmates is

such as to become a public nuisance, or a house where persons congregate

to the probable disturbance of the public peace or other commission of

crime. In England, by the Disorderly Houses Act 1751, the term includes

common bawdy houses or brothels,[1] common gaming houses, common betting

houses and disorderly places of entertainment. The keeping of such is a

misdemeanour punishable by fine or imprisonment, and in the case of a

brothel also punishable on summary conviction by the Criminal Law

Amendment Act 1885; the letting out for gain for indiscriminate

prostitution of a room or rooms in a house will make it as much a

brothel in law as if the whole house were let out for the purpose.

Where, however, a woman occupies a house or room which is frequented by

men for the purpose of committing fornication with her, she cannot be

convicted of keeping a disorderly house. See also PROSTITUTION.
