​ALLSTON, WASHINGTON (1779–1843), American historical painter and poet, was born on the 5th of November 1779 at Waccamaw, South Carolina, where his father was a planter. He graduated at Harvard in 1800, and for a short time pursued his artistic studies at Charleston with Edward Greene Malbone (1777–1807) the miniature painter, and Charles Fraser (1782–1860). With the former, in 1801, he went to London, and entered the Royal Academy as a student of Benjamin West, with whom he formed a lifelong friendship. In 1804 he went to Paris, and, after a few months’ residence there, to Rome, where he spent the greater part of the next four years. During this period he became intimate with Coleridge and Thorwaldsen. From 1809 to 1811 he resided in his native country, and from 1811 to 1817 he painted in England. After visiting Paris a ​second time, he returned to the United States, and practised his profession at Boston (1818–1830), and afterwards at Cambridge, Massachusetts, where he died on the 9th of July 1843. He was elected an associate of the Royal Academy in 1819. In colour and the management of light and shade Allston closely imitated the Venetian school, and he has hence been styled the “American Titian.” Many of his pictures have Biblical subjects, and Allston himself had a profoundly religious nature. His first considerable painting, “The Dead Man Revived,” executed shortly after his second visit to England, and now at the Pennsylvania Academy of Fine Arts in Philadelphia, gained a prize of 200 guineas. In England he also painted his “St Peter Liberated by the Angel,” “Uriel in the Sun” (at Stafford House), “Jacob’s Dream” (at Petworth) and “Elijah in the Wilderness.” To the period of his residence in America belong “The Prophet Jeremiah” (at Yale), “Saul and the Witch of Endor,” “Miriam,” “Beatrice,” “Rosalie,” “Spalatro’s Vision of the Bloody Hand,” and the vast but unfinished “Belshazzar’s Feast” (in the Boston Athenaeum), at which he was working at the time of his death. As a writer, Allston shows great facility of expression and imaginative power. His friend Coleridge (a portrait of whom by Allston is in the National Gallery) said of him that he was surpassed by no man of his age in artistic and poetic genius. His literary works are–The Sylphs of the Seasons and other Poems (1813), where he displays true sympathy with nature and deep knowledge of the human heart; Monaldi (1841), a tragical romance, the scene of which is laid in Italy; and Lectures on Art, edited by his brother-in-law, R. H. Dana the novelist (1850).

# 1911 Encyclopædia Britannica/Alluvion

See also Alluvion on Wikipedia; and our 1911 Encyclopædia Britannica disclaimer.
​ALLUVION (Lat. alluvio, washing against), a word taken from Roman law, in which it was one of the examples of accessio, that is, acquisition of property without any act being done by the acquirer. It signifies the gradual accretion of land or formation of an island by imperceptible degrees. If the accretion or formation be by a torrent or flood, the property in the severed portion or new island continues with the original owner until the trees, if any, swept away with it take root in the ground. Alluvion never attached at all in the case of agri limitati, that is, lands belonging to the state and leased or sold in plots. Dig. xli. 1, 7, is the main authority. English law is in general agreement (except as to agri limitati) with Roman, as appears from the judgment in Foster v. Wright, 1878, 4 C.P.D. 438. The Scottish law, as laid down by the House of Lords in Earl of Zetland v. Glover Incorporation, 1872, L.R. 2 H.L., Sc., 70, is in accordance with the English. (See Water Rights.)

​AIKEN, a city and the county-seat of Aiken county, South Carolina, U.S.A., 17 m. E.N.E. of Augusta, Georgia. Pop. (1890) 2362; (1900) 3414 (2131 of negro descent); (1910) 3911. It is served by the Southern railway, and by an electric line connecting with Augusta. Aiken is a fashionable winter resort, chiefly frequented by Northerners, and is pleasantly situated about 500 ft. above sea level in the heart of the famous sand-hill and pine-forest region of the state. The dry and unusually equable temperature (mean for winter 50° F., for spring 57° F., and for autumn 64° F.) and the balmy air laden with the fragrance of the pine forests have combined to make Aiken a health and pleasure resort; its climate is said to be especially beneficial for those afflicted with pulmonary diseases. There are fine hotels, club houses and cottages, and the Palmetto Golf Links near the city are probably the finest in the southern states; fox-hunting, polo, tennis and shooting are among the popular sports. There are some excellent drives in the vicinity. The city is the seat of the Aiken Institute (for whites) and the Schofield Normal and Industrial School (for negroes). There are lumber mills, cotton mills and cotton-gins; and cotton, farm products and artificial stone are exported. Considerable quantities of aluminium are obtained from the kaolin deposits in the vicinity. The city’s water supply is obtained from artesian wells. Aiken was settled in the early part of the 19th century, but was not incorporated until 1835, when it was named in honour of William Aiken (1806–1887), governor of the state in 1844–1847, and a representative in Congress in 1851–1857.

​AIKIN, JOHN (1747–1822), English doctor and writer, was born at Kibworth-Harcourt, and received his elementary education at the Nonconformist academy at Warrington, where his father was tutor. He studied medicine in the university of Edinburgh, and in London under Dr William Hunter. He practised as a surgeon at Chester and Warrington. Finally, he went to Leyden, took the degree of M.D. (1780), and in 1784 established himself as a doctor in Yarmouth. In 1792 he removed to London, where he practised as a consulting physician. But he concerned himself more with the advocacy of liberty of conscience than with his professional duties, and he began at an early period to devote himself to literary pursuits. In conjunction with his sister, Mrs Barbauld (q.v.), he published a popular series of volumes entitled Evenings at Home (6 vols., 1792–1795), excellently adapted for elementary family reading, which were translated into almost every European language. In 1798 Dr Aikin retired from professional life and devoted himself with great industry to various literary undertakings, among which his General Biography (10 vols., 1799–1815) holds a conspicuous place. Besides these, he published Biog. Memoirs of Medicine (1780); Lives of John Selden and Archbishop Usher (1812) and other works. He edited the Monthly Magazine from 1796 to 1807, and conducted a paper called the Athenaeum from 1807 to 1809, when it was discontinued. Aikin died in 1822.
His daughter, Lucy Aikin (1781–1864), born at Warrington on the 6th of November 1781, had some repute as a historical writer. After producing various books for the young, and a novel, Lorimer (1814), she published in 1818 her Memoirs of the Court of Queen Elizabeth, which passed through several editions. This was followed by Memoirs of the Court of James I. (1822), Memoirs of the Court of Charles I. (1833) and a Life of Addison (1843). Miss Aikin died at Hampstead, where she had lived for forty years, on the 29th of January 1864.

​AIKMAN, WILLIAM (1682–1731), British portrait-painter, was born at Cairney, Forfarshire. He was intended by his father for the bar, but followed his natural bent by becoming a pupil under Sir John Medina, the leading painter of the day in Scotland. In 1707 he went to Italy, resided in Rome for three years, afterwards travelled to Constantinople and Smyrna, and in 1712 returned home. In Edinburgh, where he practised as a portrait-painter for some years, he enjoyed the patronage of the duke of Argyll; and on his removal to London in 1723 he soon obtained many important commissions. Perhaps his most successful work was the portrait of the poet Gay. He also painted portraits of himself, Fletcher of Saltoun, William Carstares and Thomson the poet. The likenesses were generally truthful and the style was modelled very closely upon that of Sir Godfrey Kneller. Aikman held a good position in literary society and counted among his personal friends Swift, Pope, Thomson, Allan Ramsay, Somervile and Mallet.
# 1911 Encyclopædia Britannica/Ailsa Craig

See also Ailsa Craig on Wikipedia; and our 1911 Encyclopædia Britannica disclaimer.
​AILSA CRAIG, an island rock at the mouth of the Firth of Clyde, 10 m. W. of Girvan, Ayrshire, Scotland. It is of conoidal form, with an irregular elliptic base, and rises abruptly to a height of 1114 ft. The only side from which the rock can be ascended is the east; the other sides being for the most part perpendicular, and generally presenting lofty columnar forms, though not so regular as those of Staffa. This island is composed of micro-granite with riebeckite, of great interest on account of the rare occurrence of this type in Britain. It is comparatively fine-grained and of a greyish colour. Its essential constituents are felspar, quartz and riebeckite—a soda amphibole. The last of these minerals occurs in small irregular patches between the idiomorphic felspars which Dr J. J. H. Teall has found to be a soda orthoclase. The rock is allied to paisanite described by C. A. Osann and has been termed ailsite by Professor M. F. Heddle. It forms part of an intrusive mass which, on the south and west cliffs of the island, has a columnar arrangement and is traversed by dykes of dolerite, most of which run in a north-west direction. The age of this mass is uncertain, as its relations to other rocks are not visible in the island. As riebeckite-granophyre has been found in Skye it may be of Tertiary age. The rock is a favourite material for curling-stones, about three-fourths (according to estimate) of those in use in the countries where the game obtains being made of it. On this account curling-stones are popularly known as “Ailsas” or “Ailsa Craigs.” A columnar cave exists towards the northern side of the island, and on the eastern are the remains of a tower, with several vaulted rooms. Two springs occur and some scanty grass affords subsistence to rabbits, and, on the higher levels, to goats. The precipitous parts are frequented by large flocks of solan geese and other sea birds. The lighthouse on the southern side shows a flashing light visible for 13 m. In 1831 the twelfth earl of Cassillis became first marquis of Ailsa, taking the title from the Craig, which was his property. When John Keats was in Girvan during his Scottish tour in 1818 he apostrophized the rock in a fine sonnet.

​AIMAK, or Eimak (Mongolian for “clan,” or section of a tribe), the name given to certain nomadic or semi-nomadic tribes of Mongolian stock inhabiting the north and north-west Afghan highlands immediately to the north of Herat. They were originally known as “chahar (the four) Eimaks,” because there were four principal tribes: the Taimani (the predominating element in the population of Ghur), the Ferozkhoi, the Jamshidi and, according to some authorities, the Hazara. The Aimak peoples number upwards of a quarter of a million, and speak a dialect said to be closely related to the Kalmuck. They are Sunnite Mahommedans in distinction from the Hazara who are Shiites. They are predominantly of Iranian or quasi-Iranian blood, while the Hazara are Turanian. They are a bold, wild people and renowned fighters.

​AIKIN, ARTHUR (1773–1854), English chemist and mineralogist, was born on the 19th of May 1773, at Warrington in Lancashire. He studied chemistry under Priestley and gave attention to the practical applications of the science. To mineralogy he was likewise attracted, and he was one of the founders of the Geological Society of London, 1807, and honorary secretary, 1812–1817. To the transactions of that society he contributed papers on the Wrekin and the Shropshire coalfield, &c. Later he became secretary of the Society of Arts, and in 1841 treasurer of the Chemical Society. In early life he had been for a short time a Unitarian minister. He was highly esteemed as a man of sound judgment and wide knowledge. He died in London on the 15th of April 1854.

# 1911 Encyclopædia Britannica/Ailanthus

See also Ailanthus on Wikipedia; and our 1911 Encyclopædia Britannica disclaimer.
​AILANTHUS (more correctly ailantus, from ailanto, an Amboyna word probably meaning “Tree of the Gods,” or “Tree of Heaven”), a genus of trees belonging to the natural order Simarubaceae. The best known species, A. glandulosa, Chinese sumach or tree of heaven, is a handsome, quick-growing tree with spreading branches and large compound leaves, resembling those of the ash, and bearing numerous pairs of long pointed leaflets. The small greenish flowers are borne on branched panicles; and the male ones are characterized by having a disgusting odour. The fruits are free in clusters, and each is drawn out into a long wing with the seed in the middle. The wood is fine grained and satiny. The tree, which is a native of China and Japan, was introduced into England in 1751 and is a favourite in parks and gardens. A silk spinning moth, the ailanthus moth (Bombyx or Philosamia cynthia), lives on its leaves, and yields a silk more durable and cheaper than mulberry silk, but inferior to it in fineness and gloss. This moth is common near many towns in the eastern United States; it is about 5 in. across, with angulated wings, and in colour olive brown, with white markings. Other species of ailanthus are: A. imberbiflora and A. punctata, important Australian timber-trees; and A. excelsa, common in India.

​AIGUN, or Aihun (also Sakhalyan-ula-khoto), a town of China, province Hei-lung-kiang, in northern Manchuria, situated on the right bank of the Amur, in a fertile and populous region, 20 m. below Blagovyeshchensk, where it occupies nearly 2 m. on the bank of the river. There is a palisaded fort in the middle of the town, inside of which is the house of the fu-tu (governor). Its merchants carry on an active local trade in grain, mustard, oil and tobacco, and some of its firms supply the Russian administration with grain and flour. During the “Boxer” rising of 1900 it was, for a few weeks, the centre of military action directed against the Russians. The population, of some 20,000, includes a few hundred Mussulmans. The town was founded first on the left bank of the Amur, below the mouth of the Zeya, but was abandoned, and the present town was founded in 1684. It was here that Count Muraviev concluded, in May 1857, the Aihun treaty, according to which the left bank of the Amur was conceded to Russia.

​ALYPIUS, a Greek writer on music whose works, with those of six others, were collected and published with a commentary and explanatory notes (Antiquae Musicae Auctores Septem, Amstel., 1652), by Mark Meibomius (1630–1711). He is said to have written before Euclid and Ptolemy; and Cassiodorus arranges his Introduction to Music between those of Nicomachus and Gaudentius. The work consists solely of a list of symbols of the various scales and modes, and is probably only a fragment.
# 1911 Encyclopædia Britannica/Alöīdae

See also Aloadae on Wikipedia; and our 1911 Encyclopædia Britannica disclaimer.
​ALŌĪDAE, or Alōadae, i.e. Otus and Ephialtes, in ancient Greek legend, the twin-sons of Poseidon by Iphimedeia, wife of Aloeus. They were celebrated for their extraordinary stature and strength. According to Homer (Od. xi. 305), they made war upon the Olympian gods and endeavoured to pile Pelion upon Ossa in order to storm heaven itself; had they reached the age of manhood, their attempt would have been successful, but Apollo destroyed them before their beards began to grow. In the Iliad (v. 365) Ares is imprisoned by them, but delivered by Hermes. Apollodorus says that they succeeded in piling Pelion upon Ossa. Another story is that they were presumptuous enough to seek Artemis and Hera in marriage, and that Artemis caused them to slay each other unintentionally on the island of Naxos, where they were afterwards worshipped as heroes. In punishment for their offences they were bound back to back with snakes to a pillar in the lower world (Hyginus, Fab. 28). The Alōīdae (here connected with ἀλωή, threshing-floor) represent the spirits of the fertile earth and agriculture, conceived of by the Greeks as engaged in combat with the Olympian gods. In contrast to these legends, Pausanias tells us that they were regarded as the first to worship the Muses on Mt. Helicon, while Diodorus represents them as historical personages, princes of Thessaly, who defeated the Thracians in Strongyle, i.e. Naxos, where they made themselves rulers, and subsequently slew one another in a quarrel.

​AMADOU, a soft tough substance used as tinder, derived from Polyporus fomentarius, a fungus belonging to the group Basidiomycetes and somewhat resembling a mushroom in manner of growth. It grows upon old trees, especially the oak, ash, fir and cherry. The fungus is cut into slices and then steeped in a solution of nitre. Amadou is prepared on the continent of Europe, chiefly in Germany, but the fungus is a native of Britain. Polyporus igniarius and other species are also used, but yield an inferior product.
# 1911 Encyclopædia Britannica/Alytes

See also Midwife toad and Common Midwife Toad on Wikipedia; and our 1911 Encyclopædia Britannica disclaimer.
​ALYTES, the midwife toad, first discovered by P. Demours in 1741, on the border of a small pond in the Jardin des Plantes, in the very act of parturition which has rendered it famous, and described as Petit crapaud mâle accoucheur de sa femelle. Alytes obstetricans is of special interest as the first known example of paternal solicitude in Batrachians, and although many no less wonderful cases of nursing instinct have since been revealed to us, it remains the only one among European forms.
Alytes obstetricans is a small toad-like Batrachian, two inches in length, of dull greyish coloration, plump form with warty skin and large eyes with vertical pupils. Although toad—like it is not really related to the toads proper, but belongs to the family Discoglossidae, characterized by a circular, adherent tongue, teeth in the upper jaw and on the palate, short but distinct ribs on the anterior vertebrae, and convex-concave vertebrae. It inhabits France, Belgium, Switzerland, Western Germany (eastwards to the Weser), Spain and Portugal. A second species, A. cisternasii, occurs in Spain and Portugal.
Alytes is nocturnal and slow in its movements. It is thoroughly terrestrial, selecting for its retreat in the daytime holes made by small mammals, or interstices between stones. Towards evening it reveals its presence by a clear whistling note, which has often been compared to the sound of a little bell, or to a chime when produced by numerous individuals. The breeding season lasts throughout spring and summer, and the female is able to spawn two, three or even four times in the year. Pairing and oviposition take place on land; the male seizes the female round the waist. The eggs are large and yellow, and produced in two rosary-like strings, as if strung together by elastic filaments continuous with the gelatinous capsules. After impregnation, the male twists them round his legs and returns to his usual retreat, going about at night in order to feed himself and to keep up the moisture of the eggs, even resorting to a short immersion in the water during exceptionally dry nights. The development of the embryo within the egg takes about three weeks. When the time for eclosion has come, the male enters the water with his burden; the larvae, in the full tadpole condition, measuring 14 to 17 millimetres, bite their way through their tough envelope, which is not abandoned by the father until all the young are liberated, and complete in the ordinary way their metamorphosis. The tadpoles grow to a large size considering that of the adult, the body equalling in size a sparrow's or even a small pigeon's egg, and they often remain more than a year in that condition.
