FOOTNOTE:

[1] According to the theory now generally adopted, the Etruscan

Volsinii occupied the site of Orvieto, which was hence called _Urbs

vetus_ in late classical and medieval times, while the Roman Volsinii

was transferred to Bolaena (see VOLSINII).

BOLSOVER, an urban district in the north-eastern parliamentary division

of Derbyshire, England, 5-1/2 m. E. of Chesterfield, on branch lines of

the Midland and the Great Central railways. Pop. (1901) 6844. It lies at

a considerable height on a sharp slope above a stream tributary to the

river Rother. The castle round which the town grew up was founded

shortly after the Conquest by William Peveril, but the existing

building, a fine castellated residence, was erected on its site in 1613.

The town itself was fortified, and traces of early works remain. The

church of St Mary is of Norman and later date; it contains some

interesting early stone-carving, and monuments to the family of

Cavendish, who acquired the castle in the 16th century. Coal-mining and

quarrying are carried on in the neighbourhood of Bolsover.

BOLSWARD, a town in the province of Friesland, Holland, 6-1/2 m. W.N.W.

of Sneek. A steam-tramway connects it with Sneek, Makkum, Harlingen and

Franeker. Pop. (1900) 6517. The Great church, or St Martin's (1446-1466)

is a large building containing some good carving, a fine organ and the

tombs of many Frisian nobles. The so-called Small church, dating from

about 1280, also contains fine carving and tombstones; and is the

remnant of a Franciscan convent which once existed here. Bolsward also

possesses a beautiful renaissance town-hall (1614-1618) and various

educational and charitable institutions, including a music and a drawing

school. It has an active trade in agricultural produce, and some

spinning-mills and tile and pottery works. The town is mentioned in 725,

when it was situated on the Middle Sea. When this receded, a canal was

cut to the Zuider Zee, and in 1422 it was made a Hansa town.

The medieval constitution of Bolsward, though in its government by eight

_scabini_, with judicial, and four councillors with administrative

functions, it followed the ordinary type of Dutch cities, was in some

ways peculiar. The family of Jongema had certain hereditary rights in

the administration, which, though not mentioned in the town charter of

1455, were defined in that of 1464. According to this the head of the

family sat for two years with the _scabini_ and the third year with the

councillors, and had the right to administer an oath to one of each

body. More singular was the influential position assigned, in civic

legislation and administration, to the clergy, to whom in conjunction

with the councillors, there was even, in certain cases, an appeal from

the judgment of the _scabini_.

See C. Hegel, _Stadte u. Gilden der germanischen Volker im

Mittelalter_ (Leipzig, 1891).

BOLT, an O. Eng. word (compare Ger. _Bolz_, an arrow), for a "quarrel"

or cross-bow shaft, or the pin which fastened a door. From the swift

flight of an arrow comes the verb "to bolt," as applied to a horse, &c.,

and such expressions as "bolt upright," meaning straight upright; also

the American use of "bolt" for refusing to support a candidate nominated

by one's own party. In the sense of a straight pin for a fastening, the

word has come to mean various sorts of appliances. From the sense of

"fastening together" is derived the use of the word "bolt" as a definite

length (in a roll) of a fabric (40 ft. of canvas, &c.).

From another "bolt" or "boult," to sift (through O. Fr. _buleter_, from

the Med. Lat. _buretare_ or _buletare_), come such expressions as in

Shakespeare's _Winter's Tale_, "The fann'd snow, That's bolted by the

northern blasts twice o'er," or such a figurative use as in Burke's "The

report of the committee was examined and sifted and bolted to the bran."

From this sense comes that of to moot, or discuss, as in Milton's

_Comus_, "I hate when vice can bolt her arguments."

BOLTON, DUKES OF. The title of duke of Bolton was held in the family of

Powlett or Paulet from 1689 to 1794. Charles Powlett, the 1st duke (c.

1625-1699), who became 6th marquess of Winchester on his father's death

in 1675, had been member of parliament for Winchester and then for

Hampshire from 1660 to 1675. Having supported the claim of William and

Mary to the English throne in 1688, he was restored to the privy council

and to the office of lord-lieutenant of Hampshire, and was created duke

of Bolton in April 1689. An eccentric man, hostile to Halifax and

afterwards to Marlborough, he is said to have travelled during 1687 with

four coaches and 100 horsemen, sleeping during the day and giving

entertainments at night. He died in February 1699, and was succeeded by

his elder son, Charles, 2nd duke of Bolton (1661-1722), who had also

been a member of parliament for Hampshire and a supporter of William of

Orange. He was lord-lieutenant of Hampshire and of Dorset, a

commissioner to arrange the union of England and Scotland; and was twice

a lord justice of the kingdom. He was also lord chamberlain of the royal

household; governor of the Isle of Wight; and for two short periods was

lord-lieutenant of Ireland. His third wife was Henrietta (d. 1730), a

natural daughter of James, duke of Monmouth. According to Swift this

duke was "a great booby." His eldest son, Charles, 3rd duke of Bolton

(1685-1754), was a member of parliament from 1705 to 1717, when he was

made a peer as Baron Pawlet of Basing. He filled many of the public

offices which had been held by his father, and also attained high rank

in the British army. Having displeased Sir Robert Walpole he was

deprived of several of his offices in 1733; but some of them were

afterwards restored to him, and he raised a regiment for service against

the Jacobites in 1745. He was a famous gallant, and married for his

second wife the singer, Lavinia Fenton (d. 1760), a lady who had

previously been his mistress. He died in August 1754, and was succeeded

as 4th duke by his brother Harry (c. 1690-1759), who had been a member

of parliament for forty years, and who followed the late duke as

lord-lieutenant of Hampshire. The 4th duke's son, Charles (c.

1718-1765), who became 5th duke in October 1759, committed suicide in

London in July 1765, and was succeeded by his brother Harry (c.

1719-1794), an admiral in the navy, on whose death without sons, in

December 1794, the dukedom became extinct. The other family titles

descended to a kinsman, George Paulet (1722-1800), who thus became 12th

marquess of Winchester. In 1778 Thomas Orde (1746-1807) married Jean

Mary (d. 1814), a natural daughter of the 5th duke of Bolton, and this

lady inherited Bolton Castle and other properties on the death of the

6th duke. Having taken the additional name of Powlett, Orde was created

Baron Bolton in 1797, and the barony has descended to his heirs.

BOLTON (or BOULTON), EDMUND (1575?-1633?), English historian and poet,

was born by his own account in 1575. He was brought up a Roman Catholic,

and was educated at Trinity Hall, Cambridge, afterwards residing in

London at the Inner Temple. In 1600 he contributed to _England's

Helicon_. He was a retainer of the duke of Buckingham, and through his

influence he secured a small place at the court of James I. Bolton

formulated a scheme for the establishment of an English academy, but the

project fell through after the death of the king, who had regarded it

favourably. He wrote a _Life of King Henry II._ for Speed's _Chronicle_,

but his Catholic sympathies betrayed themselves in his treatment of

Thomas Becket, and a life by Dr John Barcham was substituted (Wood,

_Ath. Oxon._ ed. Bliss, iii. 36). The most important of his numerous

works are _Hypercritica_ (1618?), a short critical treatise valuable for

its notices of contemporary authors, reprinted in Joseph Haslewood's

_Ancient Critical Essays_ (vol. ii., 1815); _Nero Caesar, or Monarchic

Depraved_ (1624), with special note of British affairs. Bolton was still

living in 1633, but the date of his death is unknown.

BOLTON (BOLTON-LE-MOORS), a municipal, county and parliamentary borough

of Lancashire, England, 196 m. N.W. by N. from London and 11 m. N.W.

from Manchester. Pop. (1891) 146,487; (1901) 168,215. Area, 15,279

acres. It has stations on the London & North-Western and the Lancashire

& Yorkshire railways, with running powers for the Midland railway. It is

divided by the Croal, a small tributary of the Irwell, into Great and

Little Bolton, and as the full name implies, is surrounded by high

moorland. Although of early origin, its appearance, like that of other

great manufacturing towns of the vicinity, is wholly modern. It owes not

a little to the attractions of its site. The only remnants of antiquity

are two houses of the 16th century in Little Bolton, of which one is a

specially good example of Tudor work. The site of the church of St Peter

has long been occupied by a parish church (there was one in the 12th

century, if not earlier), but the existing building dates only from

1870. There may also be mentioned a large number of other places of

worship, a town hall with fine classical facade and tower, market hall,

museums of natural history and of art and industry, an exchange,

assembly rooms, and various benevolent institutions. Several free

libraries are maintained. Lever's grammar school, founded in 1641, had

Robert Ainsworth, the Latin lexicographer, and John Lempriere, author of

the classical dictionary, among its masters. There are municipal

technical schools. A large public park, opened in 1866, was laid out as

a relief work for unemployed operatives during the cotton famine of the

earlier part of the decade. On the moors to the north-west, and

including Rivington Pike (1192 ft.), is another public park, and there

are various smaller pleasure grounds. A large number of cotton mills

furnish the chief source of industry; printing, dyeing and bleaching of

cotton and calico, spinning and weaving machine making, iron and steel

works, and collieries in the neighbourhood, are also important. The

speciality, however, is fine spinning, a process assisted by the damp

climate. The parliamentary borough, created in 1832 and returning two

members, falls within the Westhoughton division of the county. Before

1838, when Bolton was incorporated, the town was governed by a

borough-reeve and two constables appointed at the annual court-leet. The

county borough was created in 1888. The corporation consists of a mayor,

24 aldermen and 72 councillors.

The earliest form of the name is Bodleton or Botheltun, and the most

important of the later forms are Bodeltown, Botheltun-le-Moors,

Bowelton, Boltune, Bolton-super-Moras, Bolton-in-ye-Moors,

Bolton-le-Moors. The manor was granted by William I. to Roger de

Poictou, and passed through the families of Ferrers and Pilkington to

the Harringtons of Hornby Castle, who lost it with their other estates

for their adherence to Richard III. In 1485 Henry VII. granted it to the

first earl of Derby. The manor is now held by different lords, but the

earls of Derby still have a fourth part. The manor of Little Bolton

seems to have been, at least from Henry III.'s reign, distinct from that

of Great Bolton, and was held till the 17th century by the Botheltons or

Boltons.

From early days Bolton was famous for its woollen manufactures. In

Richard I.'s reign an aulneger, whose duty it was to measure and stamp

all bundles of woollen goods, was appointed, and it is clear, therefore,

that the place was already a centre of the woollen cloth trade. In 1337

the industry received an impulse from the settlement of a party of

Flemish clothiers, and extended so greatly that when it was found

necessary in 1566 to appoint by act of parliament deputies to assist the

aulnegers, Bolton is named as one of the places where these deputies

were to be employed. Leland in his _Itinerary_ (1558) recorded the fact

that Bolton made cottons, which were in reality woollen goods. Real

cotton goods were not made in Lancashire till 1641, when Bolton is named

as the chief seat of the manufacture of fustians, vermilions and

dimities. After the revocation of the edict of Nantes the settlement of

some French refugees further stimulated this industry. It was here that

velvets were first made about 1756, by Jeremiah Clarke, and muslins and

cotton quiltings in 1763. The cotton trade received an astonishing

impetus from the inventions of Sir Richard Arkwright (1770), and Samuel

Crompton (1780), both of whom were born in the parish. Soon after the

introduction of machinery, spinning factories were erected, and the

first built in Bolton is said to have been set up in 1780. The number

rapidly increased, and in 1851 there were 66 cotton mills with 860,000

throstle spindles at work. The cognate industry of bleaching has been

carried on since early in the 18th century, and large ironworks grew up

in the latter half of the 19th century. In 1791 a canal was constructed

from Manchester to Bolton, and by an act of parliament (1792) Bolton

Moor was enclosed.

During the Civil War Bolton sided with the parliament, and in February

1643 and March 1644 the royalist forces assaulted the town, but were on

both occasions repulsed. On the 28th of May 1644, however, it was

attacked by Prince Rupert and Lord Derby, and stormed with great

slaughter. On the 15th of October 1651 Lord Derby, who had been taken

prisoner after the battle of Worcester, was brought here and executed

the same day.

Up to the beginning of the 19th century the market day was Monday, but

the customary Saturday market gradually superseded this old chartered

market. In 1251 William de Ferrers obtained from the crown a charter

for a weekly market and a yearly fair, but gradually this annual fair

was replaced by four others chiefly for horses and cattle. The New Year

and Whitsuntide Show fairs only arose during the 19th century.

BOLTON ABBEY, a village in the West Riding of Yorkshire, England, 22 m.

N.W. from Leeds and 5-1/2 from Ilkley by the Midland railway. It takes

its name, inaccurately, from the great foundation of Bolton Priory, the

ruins of which are among the most exquisitely situated in England. They

stand near the right bank of the upper Wharfe, the valley of which is

beautifully wooded and closely enclosed by hills. The earliest part of

the church is of transitional Norman date; the nave, which is perfect,

is Early English and Decorated. The transepts and choir are ruined, and

the remains of domestic buildings are slight. The manor of Bolton Abbey

with the rest of the district of Craven was granted by William the

Conqueror to Robert de Romili, who evidently held it in 1086, although

there is no mention made of it in the Domesday survey. William de

Meschines and Cicely de Romili, his wife, heiress of Robert, founded and

endowed a priory at Embsay or Emmesay, near Skipton, in 1120, but it was

moved here in 1151 by their daughter, Alice de Romili, wife of William

FitzDuncan, who gave the manor to the monks in exchange for other lands.

After the dissolution of the monasteries the manor was sold in 1542 to

Henry Clifford, 2nd earl of Cumberland, whose descendants, the dukes of

Devonshire, now hold it.

(ed. Morant, 1878); Dugdale's _Monasticon Anglicanum_.

BOLZANO, BERNHARD (1781-1848), Austrian priest and philosopher, was born

at Prague on the 5th of October 1781. He distinguished himself at an

early age, and on his ordination to the priesthood (1805) was appointed

professor of the philosophy of religion in Prague University. His

lectures, in which he endeavoured to show that Catholic theology is in

complete harmony with reason, were received with eager interest by the

younger generation of thinkers. But his views met with much opposition;

and it was only through the protection of the archbishop, Prince

Salm-Salm, that he was enabled to retain his chair. In 1820 he was

accused of being connected with some of the students' revolutionary

societies, and was compelled to resign. Several doctrines extracted from

his works were condemned at Rome, and he was suspended from his priestly

functions, spending the rest of his life in literary work. He died at

Prague on the 18th of December 1848. The most important of his numerous

works are the _Wissenschaftslehre, oder Versuch einer neuen Darstellung

der Logik_, advocating a scientific method in the study of logic (4

vols., Sulzbach, 1837); the _Lehrbuch der Religionswissenschaft_ (4

vols., Sulzbach, 1834), a philosophic representation of all the dogmas

of Roman Catholic theology; and _Athanasia, oder Grunde fur die

Unsterblichkeit der Seele_ (2nd ed., Mainz, 1838). In philosophy he

followed Reinhard in ethics and the monadology of Leibnitz, though he

was also influenced by Kant.

Wisshaupt, _Skizzen aus dem Leben Dr Bolzanos_ (1850); Palagy, _Kant

und Bolzano_ (Halle, 1902).

BOMA (properly _Mboma_), a port on the north bank of the river Congo

about 60 m. from its mouth, the administrative capital of Belgian Congo.

Pop. about 5000. It was one of the places at which the European traders

on the west coast of Africa established stations in the 16th and 17th

centuries. It became the entrepot for the commerce of the lower Congo

and a well-known mart for slaves. The trade was chiefly in the hands of

Dutch merchants, but British, French and Portuguese firms also had

factories there. No European power exercised sovereignty, though shadowy

claims were from time to time put forward by Portugal (see AFRICA, S 5).

In 1884 the natives of Boma granted a protectorate of their country to

the International Association of the Congo.

See H.M. Stanley, _The Congo and the Founding of its Free State_

(London, 1885).

BOMB, a term formerly used for an explosive shell (see AMMUNITION) fired

by artillery. The word is derived from the Gr. [Greek: bombos], a

hammering, buzzing noise, cf. "bombard" (q.v.). At the present day it is

most frequently used of a shattering or incendiary grenade, or of an

explosive vessel actuated by clockwork or trip mechanism, employed to

destroy life or property. In naval warfare, before the introduction of

the shell gun, explosive projectiles were carried principally by special

vessels known as bomb-vessels, bombards or, colloquially, bombs.

In geology, the name "bomb" is given to certain masses of lava which

have been hurled forth from a volcanic vent by explosive action. In

shape they are spheroidal, ellipsoidal or discoidal; in structure they

may be solid, hollow or more or less cavernous; whilst in size they vary

from that of a walnut to masses weighing several tons. It is generally

held that the form is partly due to rotation of the mass during its

aerial flight, and in some cases the bomb becomes twisted by a gyratory

movement. According, however, to Dr H.J. Johnston-Lavis, many of the

so-called bombs of Vesuvius are not projectiles, but merely globular

masses formed in a stream of lava; and in like manner Professor J.D.

Dana showed that what were regarded as bombs in Hawaii are in many cases

merely lava-balls that have not been hurled through the air. Certain

masses of pumice ejected from Vulcano have been called by Johnston-Lavis

"bread-crust bombs," since they present a coating of obsidian which has

been bent and cracked in a way suggestive of the crust of a roll. It is

probable that here the acid magma was expelled in a very viscous

condition, and the crust which formed on cooling was burst by the steam

from the occluded water. Some of the bombs thrown out during recent

eruptions of Etna consist of white granular quartz, encased in a black

scoriaceous crust, the quartz representing an altered sandstone. The

bombs of granular olivine, found in some of the tuffs in the Eifel, are

represented in most geological collections (see VOLCANO).

BOMBARD (derived through Med. Lat. and Fr. forms from Gr. [Greek:

bombein], to make a humming noise), a term applied in the middle ages to

a sort of cannon, used chiefly in sieges, and throwing heavy stone

balls; hence the later use as a verb (see BOMBARDMENT). The name, in

various forms, was also given to a medieval musical instrument

("bombard," "bumhart," "pumhart," "pommer"), the forerunner of the bass

oboe or schalmey. At the present day a small primitive oboe called

_bombarde_, with eight holes but no keys, is used among the Breton

peasants.

BOMBARDIER, originally an artilleryman in charge of a bombard; now a

non-commissioned officer in the artillery of the British army, ranking

below a corporal.

BOMBARDMENT, an attack by artillery fire directed against

fortifications, troops in position or towns and buildings. In its strict

sense the term is only applied to the bombardment of defenceless or

undefended objects, houses, public buildings, &c., the object of the

assailant being to dishearten his opponent, and specially to force the

civil population and authorities of a besieged place to persuade the

military commandant to capitulate before the actual defences of the

place have been reduced to impotence. It is, therefore, obvious that

mere bombardment can only achieve its object when the amount of

suffering inflicted upon non-combatants is sufficient to break down

their resolution, and when the commandant permits himself to be

influenced or coerced by the sufferers. A threat of bombardment will

sometimes induce a place to surrender, but instances of its fulfilment

being followed by success are rare; and, in general, with a determined

commandant, bombardments fail of their object. Further, an intentionally

terrific fire at a large target, unlike the slow, steady and minutely

accurate "artillery attacks "directed upon the fortifications, requires

the expenditure of large quantities of ammunition, and wears out the

guns of the attack. Bombardments are, however, frequently resorted to in

order to test the temper of the garrison and the civil population, a

notable instance being that of Strassburg in 1870. The term is often

loosely employed to describe artillery attacks upon forts or fortified

positions in preparation for assaults by infantry.

BOMBARDON, or BASS TUBA, the name given to the bass and contrabass of

the brass wind in military bands, called in the orchestra bass tuba.

The name of bombardon is unquestionably derived from _bombardone_, the

Italian for contrabass pommer (bombard), which, before the invention of

the fagotto, formed the bass of medieval orchestras; it is also used for

a bass reed stop of 16 ft. tone on the organ. The bombardon was the very

first bass wind instrument fitted with valves, and it was at first known

as the _corno basso_, _clavicor_ or _bass horn_ (not to be confounded

with the bass horn with keys, which on being perfected became the

ophicleide). The name was attached more to the position of the wind

instruments as bass than to the individual instrument. The original

corno basso was a brass instrument of narrow bore with the pistons set

horizontally. The valve-ophicleide in F of German make had a wider bore

and three vertical pistons, but it was only a "half instrument,"

measuring about 12 ft. A. Kalkbrenner, in his life of W. Wieprecht

(1882), states that in the Jager military bands of Prussia the corno

basso (keyed bass horn) was introduced as bass in 1829, and the

bombardon (or valve-ophicleide) in 1831; in the Guards these instruments

were superseded in 1835 by the bass tuba invented by Wieprecht and J.G.

Moritz.

The modern bombardon is made in two forms: the upright model, used in

stationary band music; and the circular model, known as the helicon,

worn round the body with the large bell resting on the left shoulder,

after the style of the Roman _cornu_ (see HORN), which is a more

convenient way of carrying this heavy instrument when marching. The

bombardon, and the euphonium, of which it is the bass, are the outcome

of the application of valves to the bugle family whereby the saxhorns

were also produced. The radical difference between the saxhorns and the

tubas (including the bombardon) is that the latter have a sufficiently

wide conical bore to allow of the production of fundamental sounds in a

rich, full quality of immense power. This difference, first recognized

in Germany and Austria, has given rise in those countries to the

classification of the brass wind as "half" and "whole" instruments

(_Halbe_ and _Ganze Instrumente_). When the brass wind instruments with

conical bore and cup-shaped mouthpiece first came into use, it was a

well-understood principle that the tube of each instrument must

theoretically be made twice as long as an organ pipe giving the same

note; for example, the French horn sounding the 8 ft. C of an 8 ft.

organ pipe, must have a tube 16 ft. long; C then becomes the second

harmonic of the series for the 16 ft. tube, the first or fundamental

being unobtainable. After the introduction of pistons, instrument-makers

experimenting with the bugle, which has a conical bore of very wide

diameter in proportion to the length, found that baritone and bass

instruments constructed on the same principle gave out the fundamental

full and clear. A new era in the construction of brass wind instruments

was thus inaugurated, and now that the proportions of the bugle have

been adopted, the tubes of the tubas are made just half the length of

those of the older instruments, corresponding to the length of the organ

pipe of the same pitch, so that a euphonium sounding 8 ft. C no longer

needs to be 16 ft. long but only 8 ft. The older instruments, such as

the saxhorns, with narrow bore, have therefore been denominated "half

instruments," because only half the length of the instrument is of

practical utility, while the tubas with wide bore are styled "whole

instruments." [1] Bombardons are made in E flat and F of the 16 ft.

octave, corresponding to the orchestral bass tuba, double bass in

strings, and pedal clarinet and contrafagotto in the wood wind. The

bombardon in B flat or C, an octave lower than the euphonium,

corresponds to the contrabass tuba in the orchestra.

The bombardons possess a chromatic compass of 3-1/2 to 4 octaves. The

harmonic series consists of the harmonics from the 1st to the 8th.

[Illustration: BOMBARDON IN E FLAT.]

[Illustration: HARMONIC SERIES OF THE CONTRABASS BOMBARDON IN C.]

The lowest notes produced by the valves are very difficult to obtain,

for the lips seldom have sufficient power to set in vibration a column

of air of such immense length, at a rate of vibration slow enough to

synchronize with that of notes of such deep pitch.[2] Even when they

are played, the lowest valve notes can hardly be heard unless doubled

an octave higher by another bombardon.

Bombardons are generally treated as non-transposing instruments, the

music being written as sounded, except in France and Belgium, where

transposition is usual. The intervening notes are obtained by means of

pistons or valves, which, on being depressed, either admit the wind

into additional lengths of tubing to lower the pitch, or cut off a

length in order to raise it. Bombardons usually have three or four

pistons lowering the pitch of the instrument respectively 1, 1/2,

1-1/2 and 2-1/2 tones (in Belgium, 1, 1/2, 2 and 3 tones). The valve

system, disposal of the tubing and shape and position of the bell

differ considerably in the various models of well-known makers. In

Germany and Austria[3] what is known as the cylinder action is largely

used; for the piston or pump is substituted a four-way brass cock

operated by means of a key and a series of cranks.

In order to obtain a complete chromatic scale throughout the compass,

there must be, as on the slide-trombone, seven different positions or

lengths of tubing available, each having its harmonic series. These

different lengths are obtained on the bombardon by means of a

combination of pistons: the simultaneous use of Nos. 2 and 3 lowers

the pitch two tones; of Nos. 1, 2 and 3, three tones; of Nos. 1, 2, 3,

4, five and a half tones, &c. A combination of pistons, however, fails

to give the interval with an absolutely correct intonation, since the

length of tubing thrown open is not of the theoretical length required

to produce it. Many ingenious contrivances have been invented from

time to time to remedy this inherent defect of the valve system, such

as the six-valve independent system of Adolphe Sax; the Besson

_Registre_, giving eight independent positions; the Besson

compensating system _Transpositeur_; the Boosey automatic compensating

piston invented by D.J. Blaikley, and V. Mahillon's automatic

regulating pistons. More recently the Besson enharmonic valve system,

with six independent tuning slides and three pistons, and Rudall,

Carte & Company's new (Klussmann's patent) bore, conical throughout

the open tube and additional lengths, have produced instruments which

leave nothing to be desired as to intonation. (See VALVES and TUBA.)
