neglected to publish. Le Verrier has thus acquired,
naturally, the whole honour of the discovery; but
the merit of A. is not less. The researches of the
latter commenced earlier; his discovery, too, was
earlier ;
and it was only unfortunate for the reputa-
tion of the young astronomer that he omitted to
publish the results he had obtained. The council of
the Royal Astronomical Society shewed that they
appreciated the value of A.'s labours, by awarding
equal honours to both. In 1858, A. was appointed
to the chair of mathematics in St Andrews, which,
however, he vacated within a few months, on being
nominated to the Lowndean Professorship of Astro-
nomy, Cambridge.

ADAMS, JOHN, the second president of the United States of North America, was born at Braintree, in Massachusetts, on the 19th of October 1735. His parents were descended from a Puritan family which had emigrated from England to Massachusetts in 1640. Before the revolution, A. had distinguished himself as a jurist, and wrote in the Boston Journal an essay on Canon Law and Feudal Law (1765). He was sent by Massachusetts to the congress which commenced its sittings in ADAMS, JOHN QUINCY, the sixth president of Philadelphia in 1774.

In 1785 he came to London as the first journal, and afterwards translated into French and ambassador from the Union. George III. expressed German. In his political views, A. perfectly agreed his pleasure in receiving an ambassador who had with his father, and, consequently, he was recalled no prejudices in favour of France, the natural from Berlin when Jefferson was elected president enemy of the English crown, and A. replied: "I in 1801.

He soon became prominent as a leader of the United States, and on the retirement of of the federal party; but in later years he adroitly Washington (in 1797) became president. The changed his course, and seemed inclined towards enmity of the democratic party, which had already the party of Madison. By Madison he was sent as been excited against him, was now increased by the plenipotentiary to Russia, and afterwards to Engmeasures which he judged necessary to uphold the land. On this embassy he took a part in the negonational honour against the pretensions of France, counsel the deputies sent from America to Ghent. tiation of peace with England, and assisted with his and still more by his decided favour for a hereditary When Monroe was elected president, he recalled aristocracy.

When 85 years old, we find him still in his place as member of the convention appointed (1820) to revise the constitution of Massachusetts. He died on the 4th of July 1826, on the fiftieth anniversary of the day when he had proclaimed in congress the independ

ence of the United States.

ADAMS, JOHN COUCH, discoverer, simultaneously with Le Verrier, of the planet Neptune, was born near Launceston in Cornwall, 1819. He early manifested an aptitude for mathematics; and after the usual amount of school-training, he was sent to St John's College, Cambridge, where he attained the honour of senior wrangler, and became a mathematical tutor. In 1841, he undertook to find out the cause of the irregularities in the motion of Uranus, anticipating, indeed, his own and Le Verrier's discovery—namely, that they are due to the influence

his former political associates, he could never win the confidence of the growing party of democrats; and on the expiration of his term of office, he had estate of Quincy, near Boston; but in 1830 was to give place to General Jackson. A. retired to his chosen as representative of his district. He now

joined the party of abolitionists, and frequently raised the whole House of Representatives against himself by his incessant petitions on the slavery question. On one occasion (in 1842), in order to assert strongly in the abstract the right to petition, he went so far as to present a petition for the dissolution of the union! This was misunderstood, and turned against him. He died at Washington during the session of congress, February 23, 1848. A. was one of the most able among American statesmen of the old school, and a skilled diplomatist. See Memoirs of A. (vols. i. and ii., 1874).

ADAMS-ADDISON.

ADAMS, SAMUEL, one of the leading men of the American revolution, was born at Boston, U.S., September 27, 1722. His political leanings were early manifested; on taking the degree of A.M. at Harvard College, 1743, he maintained the affirmative of the question: Whether it be lawful to resist the supreme magistrate, if the commonwealth cannot be otherwise preserved? He intended at first to become a clergyman, but afterwards commenced a small business, and was made a collector of taxes. He displayed on all occasions an unflinching zeal for popular rights, and was, by the patriotic party, placed in the legislature in 1766. A. was a member of the first congress, and signed the declaration of independence in 1776. He took an active part in framing the constitution of Massachusetts, and was for several years president of the senate of that state. He held the office of its lieutenant-governor from 1789 to 1794, and of governor from that time till 1797. He then retired from public life, and died at Boston, October 2, 1802, poor as he had lived. A.'s character was one of great courage and determination. He was, at the same time, somewhat narrow-minded and bigoted, both in religion and politics. He was prejudiced against Washington, whose conduct of the war his ignorance of military matters led him to think weak and dilatory; and the confidence reposed in Washington, as first president of the republic, seemed to A. to savour of aristocracy.

ADA'NA, a Turkish ejalet or province in the south-east of Asia Minor, derives its name from its chief city Adana, containing 25,000 inhabitants. The city is distant almost thirty miles from Tarsus, on the way to Aleppo, commands the pass of the Taurus mountains, and carries on a considerable trade between Syria and Asia Minor. Pompey peopled the territory of Adana with pirates. The Syrian kings made the place a city, under the name of Antiochia ad Sarum, and on the ruins of Antiochia the caliph Haroun al Raschid built Adana. The present inhabitants are mostly Turks, mixed with some Greeks and Armenians.

the time of his death, August 3, 1806, he was earnestly devoted to the prosecution of his plan, too vast to be carried out by an individual.

ADANSO'NIA, a genus of the natural order Sterculiaceae (q. v.), sub-order Bombaceae, named by Linnæus in honour of the botanist Adanson (q. v.), and distinguished by a simple deciduous calyx, a very long style, with numerous stigmas, and a woody capsule containing a farinaceous pulp. The only known species, A. digitata, the Baobab, also called the Monkey-bread Tree, is a native of the tropical parts of Western Africa, but now introduced into the East and West Indies. It is the largest known tree-not indeed rising to a very great height, but exceeding all other trees in the thickness of its trunk (20-30 feet). Even its branches (60-70 feet long) are often as thick as the stems of large trees, and they form a hemispherical head of 120-150 feet in diameter; their outermost boughs drooping to the ground. The leaves are digitate or 7-fid; the flowers are white and extremely large, on drooping peduncles of a yard in length. The fruit (Monkey-bread) is of the size of a citron. The bruised leaves (Lalo) are mixed with the daily food of the inhabitants of tropical Africa; and Europeans in that country employ them as a remedy for diarrhoea, fevers, and diseases of the urinary organs. The pulp of the fruit, which is slightly acid and pleasant to the taste, is eaten with or without sugar; and the expressed juice mixed with sugar is much esteemed as a beverage, being very refreshing, effectual in quenching thirst, and regarded as a specific in putrid and pestilential fevers. The bark is said to be powerfully febrifugal.

ADDA, the Latin Addua, a river of Lombardy, rising in the Rhætian Alps above Bormio. It flows into the Lake of Como, issuing from which below Lecco, it traverses the plain of Lombardy in a direction S.S.E., passing Lodi and Pizzighetone, and falls into the Po about 8 miles above Cremona. It formerly bounded the republic of Venice and the duchy of Milan.

ADDER, a common English name of the Viper (q. v.), but also often more vaguely used for poisonous serpents of the family Viperidae. Where the name occurs in the authorised version of the Scriptures, it appears to be always in this vague sense; although the terms in the same places of the original may probably be more precise. A very venomous serpent of New South Wales (Acanthopis tortor) is sometimes called the Death or Black A.

A'DANSON, MICHEL, a celebrated French botanist, born at Aix, April 7, 1727. He soon left the clerical profession, for which he was educated, and devoted himself to the study of natural history. In his early career, he entertained the ambition of superseding the Linnæan system by a clearer and more comprehensive method of arrangement. When about twenty-one years old, he went to Senegal in Africa, and, fearless of the unwholesome ADDISON, JOSEPH, the son of an eminent clergy. climate, stayed there five years, afterwards returning man of the Church of England, was born at Milston, to France, with a large collection of specimens in near Amesbury, in Wiltshire, on the 1st May 1672. natural history.

He was originally intended for the church, Histoire Naturelle du Senégal, and, in 1763, his but various circumstances conspired to draw him Familles des Plantes, in which he endeavoured to aside into literature and politics; the principal of give a new form to botany; but he could not prevail which were, his acquaintance with Dryden, who against the established Linnæan system.

which occurred in the next year, presented a brilliant opportunity to him, which he did not fail to make the most of. The ministry wished the victory commemorated in verse, and A. was appointed to do it. Lord Godolphin, the treasurer, was so excessively delighted with the first half of the triumphal poem, that before the rest was finished, he made A. a Commissioner of Appeals. The poet was now fairly involved in politics. He accompanied Halifax to Hanover; became under-secretary of state in 1706, and in 1709 went to Ireland in the capacity of secretary to the Lord-lieutenant, where he also obtained the office of Keeper of the Records, worth £300 a year. In the same year, his friend Steele commenced The Tatler, to which A. soon became a frequent contributor. He also wrote a number of political articles in the Whig Examiner. On the 1st of March 1711, appeared The Spectator,

married the Dowager-countess of Warwick, and in the following year was appointed secretary of state. For neither of his new situations was he at all suited. Lady Mary Wortley Montague, in a letter to Pope, expressed her fear that a day might come when he would be heartily glad to resign both.' He was so extremely timid and awkward in large companies, that it was out of the question for him to attempt debating in parliament a thing indispensable to one in his position. He consequently resigned in 1718. Then as to the other matter, Dr Johnson sarcastically remarks, that the lady was persuaded to marry him on terms much like those on which a Turkish princess is espoused-to whom the sultan is reported to pronounce: "Daughter, I give thee this man for thy slave."' No one can doubt that this marriage was a mistake on the part of A. His health had been for some time in a very precarious state; and at length, after an illness of a few months, he died at Holland House, Kensington, on the 17th June 1719, in the 48th year of his age, three years after what Thackeray calls his splendid but dismal union.' A. had appointed Mr Tickell his literary executor, who published his works shortly after in 4 vols. quarto. Besides those to which we have incidentally alluded, he wrote A Treatise on the Usefulness of Ancient Medals, Especially in Relation to the Latin and Greek Poets, which, however, excited little interest. He also left an unfinished work on The Evidences of the Christian Religion. But the most delightful and original of all his productions is that series of sketches in The Spectator of which Sir Roger de Coverley is the central figure, and Sir Andrew Freeport and Will Honeycomb the side ones. Sir Roger himself is an absolute creation; the gentle yet vivid imagination, the gay and cheerful spirit of humour, the keen, shrewd observation, and fine raillery of foibles which A. has displayed in this felicitous characterisation, render it a work of pure genius. But A. in prose is always excellent. He has given a delicacy to English sentiment, and a modesty to English wit which it never knew before. Elegance, which in his predecessors had been the companion of immorality, now appeared as the advocate of virtue. Every grace was enlisted in the cause of a benign the most popular and elegant miscellany in English and beautiful piety. His style, too, is perfect after literature.

It was generally understood to have a political as well as a poetical inspiration; but so prudently had A. expressed himself, that both parties, Whig and Tory, received its frigid declamation with rapture. It was translated into various European languages; and even the monarch of French criticism, Voltaire, held -Shakspeare a barbarian in tragedy compared with our author. All the laurels of Europe,' says Thackeray, 'were scarcely sufficient for the author of this "prodigious" poem.' Every one in England praised it except Dennis. A. was called the 'great Mr A.' after that wonderful night in the theatre, when, as Pope says, 'the numerous and violent claps of the Whig party on the one side, were echoed back by the Tories on the other.' This enthusiasm was a delusion which time has effectually dispelled. In 1716, A. philanthropy, and refinement.

must, however, be admitted, that since the beginning
of the present century, their popularity has under-
gone a considerable decline. The chief cause of
this is, that much in them relates to temporary

it is certain that there are in the collected works of

A'DEN, a peninsula and town on the south-west coast of Arabia. The most southern promontory of the peninsula, Cape Aden, is in N. lat. 12° 47', and E. long. 45° 9′. This peninsula, the area of which is 18-20 square miles, is doubtless of volcanic origin, and consists chiefly of a range of hills not exceeding 1776 feet in height. It is joined to the mainland by narrow, level, and sandy isthmus. In a valley which forms the crater of a submarine volcano, stands the town of A., which is also named from the neigh bouring promontory, Bab-el-Mandeb, or the Gate of Mandeb. It was styled by the native Arabs Aden or Eden (Paradise), on account of its fine climate and great commerce, for which it was celebrated from the oldest times.

A'DERSBACH ROCKS, a remarkable labyrinthine group of sandstone rocks situated near the village of Adersbach, in Bohemia. The aspect of some parts of the group has been compared to that of a city ruined by a conflagration. One of the pinnacles rises to a height of 218 feet. The structure of the rocks has been produced, not by any commotion of the earth, but by the influences of rain, frost, and other atmospheric changes, wearing down the soft sandstone into many fantastic forms. During the Thirty Years' War, the miserable people of Bohemia often found refuge in this locality.

ADHESION, in Pathology, is when two surfaces of a living body become united. If they have been separated by the cut of a sharp instrument, and are immediately and accurately placed in apposition to each other, they may adhere at once without any apparent bond of union. But, generally, the blood-vessels of the part pour out, between the surfaces, a fluid, consisting of the watery part of the blood holding fibrine in solution. The liquid part of this is reabsorbed or escapes from the wound, leaving the fibrine, in which first cells are developed, and then blood-vessels: it is now a living tissue, and forms a uniting medium between the sides of the wound.

Serous membranes, as the pleura, pour out this fluid when inflamed; and hence the adhesions so often the result of pleurisies.-If two granulating (see GRANULATIONS) surfaces be kept in contact, the opposite granulations may fuse together, and the wound unite by secondary adhesion.

A'DJECTIVE is the name of one of the classes into which grammarians have divided words. An adjective is so called, not so much from its being added to a substantive, as because it adds to the meaning, or more exactly describes the object, than the simple substantive or general name does. The effect of an adjective is also to limit the application of the name to which it is joined. Thus, when tall is joined to man, there is more meaning conveyed; there are more properties suggested to the mind by the compound name tall man, than by the simple name man; but tall man is not applicable to so many individuals as man, for all men that are not tall are excluded.-Nouns, or names of things, are often used in English as adjectives; thus, we say a silver chain, a stone wall. In such expressions as Income Tax Assessment Bill,' Income plays the part of an adjective to Tax, which is, in the first place, a noun; the two together then form a sort of compound adjective to Assessment; and the three, taken together, a still more compound adjective to Bill, which, syntactically, is the only noun in the expression. This usage seems peculiar to English.Languages differ much in their way of using adjectives. In English, the usual place of the adj. is before the noun. This is also the case in German; but in French and Italian, it comes after. In these languages, again, the adj. is varied for gender, number, and, in the German, for case. In English it is invariable; and in this simplicity there is a decided superiority; for in modern languages these changes in the adj. serve no purpose. The only modification the Eng. A. is capable of is for degrees of comparison.

ADIA'NTUM. See MAIDENHAIR. A'DIGÉ, after the Po, the most important river in Italy, rises in the Rhætian Alps. Various streamlets descend from these mountains, and, uniting at Glarus, form the Etsch, which is, properly speaking, the beginning of the A., and the name by which the entire river is known in Germany. From Glarus it flows east into the Tyrol, then, after a slight détour to the south-east, it flows due south past Trent and Roveredo, into Lombardy, and, passing Verona, takes a south-eastern sweep, discharging its waters into the Adriatic, between the mouths of the Po and the Brenta. In ancient times (when it was called the Athesis), it had a more northerly embouchure.
