GUGLIELMI, Peter, was born in 1727, at Massa Carrara, where his father, Giacomo Guglielmi was chapel-master of the duke of Modena. He studied music with his father until his eighteenth year, and afterwards went to Naples to the conservatorio di Loretto, then under the direction of the celebrated Durante. Guglielmi showed little taste for music, but Durante kept him to the study of counterpoint and of composition. He left the institution in his twenty-eighth year, and immediately began to compose comic and heroic operas for the Italian theatre. In each he was equally successful. He was invited to Vienna, to Madrid, and to London, and returned to Naples about the fiftieth year of his age. Here he made a most brilliant display of his talents. Two masters, Cimarosa and Paesiello had taken possession of the great theatre in Naples, and contended for the palm. He took a noble revenge upon the latter, of whom he had some cause to complain. To every work of his adversary he opposed another, and was always victorious. In 1793, Pius VI named him chapel-master of St. Peter's, which gave him an opportunity of distinguishing himself in sacred music. He has left more than 200 pieces, remarkable for their simple and beautiful airs, for their clear and rich harmony, and for their spirit and originality. He died in 1804, in his 77th year. His son, Peter Charles, is likewise a distinguished composer.

GUIANA; a country of South America. This name was formerly given to the country extending from the Orinoco on the north to the Amazon on the south; but the part called Spanish Guiana now forms a province of Colombia, and Portuguese Guiana now belongs to Brazil. The rest of the country belongs to the English, Dutch and French. English Guiana contains three small colonies, viz. Essequibo, Demerara and Berbice. The principal town is Stabroek. Dutch Guiana, often called Surinam, is watered by the river Surinam. Parimaribo, the capital, is a pleasant town. French Guiana, called also Cayenne, is noted for producing the Cayenne pepper. Cayenne, the capital, is situated on an island. Guiana is of a mild climate for a tropical country. Along the sea-shore, and for a considerable way into the interior, the country is an extensive and uniform plain of unequalled fertility. In the interior, it rises into mountains, which frequently contain a great variety of mineral sub

stances. Rich and fertile valleys are interspersed throughout these mountainous tracts. These uncultivated parts are covered with immense forests, which are intersected with deep marshes, and by extensive savannas or plains covered with luxuriant herbage. The country is watered by the tributary streams of the Orinoco and the Amazon. Guiana is overspread with the most luxuriant vegetation, abounding in the finest woods, in fruits of every description, and in an infinite variety of both rare and useful plants. Many of the trees grow to the height of 100 feet; they consist of every variety, of such as are valuable for their hardness and durability, as well as of others, which are richly veined, capable of taking the finest polish, and well adapted for all sorts of ornamental furniture; while others yield valuable dyes, or exude balsamic and medicinal oils. The fruit trees are in great variety, and the fruits they yield are of the most exquisite delicacy and flavor. Wild animals and beasts of prey are abundant. These are the jaguar, which is a powerful and ferocious animal; the cougar, or red tiger, resembling a greyhound in shape, but larger in size; the tiger cat; the crabbodago, not much larger than a common cat, and exceedingly ferocious; the coatimondi, or Brazilian weasel; the great ant-bear; the porcupine; the hedgehog; the armadillo; the sloth; the opossum of different kinds; the deer; the hog; the agouti; the lizard; the chameleon. In the rivers are to be found the alligator; the tapir, resembling the hippopotamus of the old continent, but of much smaller size, not being larger than a small ass, but much more clumsy; the manati, or sea-cow, about 16 feet in length; the paca, or spotted cony; and the pipa, a hideous and deformed animal. Of the serpent tribe there are various species, from the large aboma snake, which grows to the length of 20 and 30 feet, to those of the smallest size. The woods of Guiana are filled with every variety of the feathered species, many of which, there is reason to believe, are but imperfectly known to naturalists. Those most commonly seen are the crested eagle, a very fierce bird, and very strong; the vulture; the owl; the black and white butcher-bird; parrots of different kinds, and of the most brilliant plumage; the toucan; the pelican; the tiger-bird; herons of different kinds; the flamingo; the humming-bird of various species; the plover; the woodpecker; the mocking-bird. The vampire bat is also

fait en 1773, Ouvrage posthume de Guibert, publié par sa Veuve, et précédé d'une Notice historique sur la Vie de l'Auteur, par Toulongeon, avec Figures (1803), was but a mere sketch for the author's use, but is interesting for its descriptions and anecdotes of celebrated men, especially of Frederic II, whose great character Guibert passionately admired. His tragedies have not retained their place upon the stage. In 1779 appeared his Défense du Système de Guerre moderne. In 1786, he became a member of the French academy. In 1787, he wrote his famous eulogy on Frederic II, one of the most splendid monuments ever raised to the memory of this great king. Guibert's eulogies, among which are one upon Thomas, and another upon l'Espinasse, are among his most finished works. Vigor, fancy, clearness, and a certain artlessness, engage the reader, and cause him to excuse many instances of negligence. Guibert was a field-marshal, and member of the council of war-an of

died in 1790, in the 47th year of his age. He was distinguished for ambition and for activity of spirit.

found in Guiana, and grows to an enormous size, measuring about 324 inches between the tips of the two wings. It sucks the blood of men and cattle when they are fast asleep. After it is full, it disgorges the blood, and begins to suck afresh, until it reduces the sufferer to a state of great weakness. The rivers of Guiana abound with fish, many of which are highly prized by the inhabitants; and, owing to the heat and moisture of the climate, insects and reptiles of all sorts are produced in such abundance, that the annoyance from this source is inconceivable. These insects are flies, ants, mosquitoes, cockroaches, lizards, jack-spaniards, a large species of wasp, fire-flies, centipedes, &c. The native inhabitants of Guiana are continually receding from the districts which are occupied by the Europeans. They chiefly consist of the following tribes, viz., the Caribbees, the Worrows, the Accawaws, the Arrowauks. From the earliest period, the Dutch colonies in Guiana have been exposed to dep-fice which gave him much trouble. He redations from fugitive Negroes, who, at different periods, have been driven, by the cruelty of their masters, to take refuge in the woods. At one time, the colony was threatened with destruction from these bands of deserter slaves. As the European troops who were sent against this enemy generally fell a prey to the climate, a corps of manumitted Negroes was formed, by whom the slaves were pursued into the woods; and the colony has been since freed from this source of annoyance. GUIBERT, Jacques-Antoine-Hippolite, count of, was born at Montauban in 1743, educated at Paris, and accompanied his father to Germany, during the seven years' war, at the age of 13. In the battle of Bellinghausen, in 1761, finding that the orders which he carried were rendered unseasonable by a change of circumstances, he had the boldness to alter them, and adapt them to the existing state of affairs. In the Corsican war in 1766, he obtained the cross of St. Louis, and soon after, with the rank of colonel, the chief command of the newly-levied Corsican legion. He employed his leisure hours in literary occupations, and his Essai général de Tactique, précédé d'un Discours sur l'État de la Politique et de la Science militaire en Europe (London, 1772), probably written during the German campaigns, attracted the more attention, as at that time a reform was going on in almost all the armies. He afterwards travelled for military purposes through Germany. His journal, Journal d'un Voyage en Allemagne,

GUICCIARDINI, Francis, a celebrated historian, was born March 6, 1482, at Florence, where his family was of distinguished rank. He obtained so great a reputation as a jurist, that in his 23d year he was chosen professor of law, and, although he had not yet reached the lawful age, was appointed ambassador to the court of Ferdinand the Catholic, of Spain. When Florence (1512) had lost her liberty through the usurpation of the Medici, he entered the service of that family, which soon availed themselves of his talents. He was invited by Leo X to his court, and intrusted with the government of Modena and Reggio. This office he discharged also under Adrian VI, to the general satisfaction; and afterwards, when Clement VII (de' Medici) ascended the papal chair, Guicciardini was sent, as luogotenente of the pope, to Romagna, then torn by the factions of the Guelfs and Gibelines, and infested by robbers, where, by a severe and upright administration of justice, he soon succeeded in restoring tranquillity. He also contributed here in other ways to the public good, by constructing roads, by erecting public buildings, and by founding useful institutions. Having been appointed lieutenant-general of the pope, he defended Parma with great valor, when besieged by the French (at least he says so in his own history; Angeli, author of a history of Parma, accuses liim, on the

contrary, of great cowardice). At a later period, after the death of Giovanni de' Medici, Guicciardini was invited by the Florentines to succeed him in the command of the famous bande nere; but the pope still claimed his services for a time. Having quelled an insurrection in Bologna, he returned, in spite of the instances of the holy father, to his native city, where, in 1534, he began his great work, on the History of Italy, which has since been repeatedly published, and has obtained for him great reputation. It extends from 1490 to 1534. In his retirement he was not without influence on state affairs, and his counsels often restrained the prodigality and the ambition of Alessandro de' Medici, who es teemed him very highly, as did likewise Charles V, whose interests he had promoted in his negotiations at Naples, and who, when his courtiers once complained that he preferred the Florentines to them, answered, "I can make a hundred Spanish grandees in a minute, but I cannot make one Guicciardini in a hundred years." When Alessandro de' Medici was murdered by one of his relations (Lorenzino, 1536), and the Florentines, under the direction of cardinal Cibo, wished to restore the republican constitution, Guicciardini opposed it with all his power, and maintained that to preserve the state from becoming the prey of foreigners or of factions, the monarchical form of government ought to be retained. His eloquence and the force of his arguments triumphed, and Cosmo de' Medici was proclaimed grandduke of Florence. Guicciardini died in 1540, and, according to his own directions, was buried, without pomp, in the church Santa Felicità in Florence. It is related of him,that his love for study was so great,that, like Leibnitz, he often passed two or three days without rest or food. One of his works, which was afterwards translated into French, his Advice on political Subjects, was published in 1525, at Antwerp. The Florentine J. B. Adriani (who died 1579), in his Istoria de' suoi Tempi (new edition, 1823), which may be regarded as a continuation of the work of Guicciardini, has given a good narrative of events between 1536 and 1574. This work was first published after the death of the author in 1583. The reader of Guicciardini is sometimes offended by a want of method. A more important defect, however, is, that his statements cannot always be depended on as derived from the best sources, so that he must be read with caution. One of the best criticisms on Guicciardini is contained in Leopold Ranke's

Zur Kritik neuerer Geschichtschreiber (Leipsic and Berlin, 1824). Guicciardini has often been called the Italian Polybius. Of the 20 books of his history, the 4 last are unfinished, and are to be considered only as rough drafts. He is much too prolix, and the satirist Boccalini, in his Ragguagli di Parnaso, makes a Spartan, who has been condemned to read Guicciardini for having used three words when he could have expressed his meaning in two, faint away at the first sentence. Guicciardini also wrote poems. In the beginning of a poetical epistle, entitled Supplicazione d'Italia al Cristianissimo Re Francesco Primo, he expresses the feeling so commonly exhibited by Italian writers, ever since the time of Dante, in regard to the distracted state of their country. The epistle begins thus :—

Italia affitta, nuda e miseranda,

Ch' or de' principi suoi stanca si lagna, A Te, Francesco, questa carta manda. GUIDES; in some armies, persons particularly acquainted with the ground, who serve in the staff, to give the necessary information, and point out the best route for an army. As it is, however, impossible always to have officers of this kind, some armies have geographical engineers attached to the staff, whose particular studies are geography and topography. Napoleon gave the name of guides to his first body of guards, formed after he had been on the point of being surprised and taken prisoner in a castle on the Mincio (see his own account, Las Cases' Mémorial, &c. vol. ii, p. 3, ed. of 1824.)

GUIDO ARETINO. (See Aretino.)

GUIDO RENI; the most charming and graceful painter whom Italy ever produced. His family name was Reni, but he is always called Guido. In fact, many of the old masters are best known by their Christian names. He was born at Bologna, in 1575. His father, Samuel Reni, an excellent musician, at first intended that his son should devote himself to music, for which he showed some talent; but he soon discovered in the boy a greater genius for painting, and had him instructed by the Dutch artist Dionysius Calvaert (q. v.), who was then in high repute at Bologna. In this celebrated school, Guido is said to have studied chiefly the works of Albert Dürer. This becomes probable if we consider some of his earlier works, in which, particularly in the drapery, occasional resemblance may be traced to the style of Albert Dürer. In the mean time, the school of the Caracci, at Bologna, on account of its novelty and superior
