 modern barracks, however, are arranged more on the pavilion system with separate blocks; but the single block system is well liked on account of its compactness and the facility it gives for supervision; it is also more satisfactory from the architectural point of view. The system of allotment and arrangement of accommodation for these two great armies does not differ much, except in detail, from that adopted by the British army. The floor and cubic space allotted per man is a little less; accommodation for officers is not usually provided, except to a limited extent, unless the barracks are on a country site. The German army, however, now provides every regiment with a fine officers’ mess-house furnished at the public expense. Married quarters for some of the non-commissioned officers are provided, but not for privates. American barracks are interesting, as providing for perhaps a higher class of recruit than usual; they are well designed and superior finish internally is given. The barracks are arranged usually on the separate block system, and centre round a post-exchange or soldiers’ club, which is a combined recreation establishment, gymnasium and sergeants’ mess, with bath-house attached. Canteens for the sale of liquor were abolished in 1901.

 BARRANDE, JOACHIM (1799–1883), Austrian geologist and palaeontologist, was born at Saugues, Haute Loire, on the 11th of August 1799, and educated in the École Polytechnique at Paris. Although he had received the training of an engineer, his first appointment was that of tutor to the duc de Bordeaux (afterwards known as the comte de Chambord), grandson of Charles X., and when the king abdicated in 1830, Barrande accompanied the royal exiles to England and Scotland, and afterwards to Prague. Settling in that city in 1831, he became occupied in engineering works, and his attention was then attracted to the fossils from the Lower Palaeozoic rocks of Bohemia. The publication in 1839 of Murchison’s Silurian System incited Barrande to carry on systematic researches on the equivalent strata in Bohemia. For ten years (1840–1850) he made a detailed study of these rocks, engaging workmen specially to collect fossils, and in this way he obtained upwards of 3500 species of graptolites, brachiopoda, mollusca, crustacea (particularly trilobites) and fishes. The first volume of his great work, Système silurien du centre de la Bohême (dealing with trilobites), appeared in 1852; and from that date until 1881, he issued twenty-one quarto volumes of text and plates. Two other volumes were issued after his death in 1887 and 1894. It is estimated that he spent nearly £10,000 on these works. In addition he published a large number of separate papers. In recognition of his important researches the Geological Society of London in 1855 awarded to him the Wollaston medal.

The term Silurian was employed by Barrande, after Murchison, in a more comprehensive sense than was justified by subsequent knowledge. Thus the Silurian rocks of Bohemia were divided into certain stages (A to H)—the two lowermost, A and B without fossils (Azoic), succeeded by the third stage, C, which included the primordial zone, since recognized as part of the Cambrian of Sedgwick. The fourth stage (Étage D), the true lower Silurian, was described by Barrande as including isolated patches of strata with organic remains like those of the Upper Silurian. These assemblages of fossils were designated “Colonies,” and regarded as evidence of the early introduction into the area of species from neighbouring districts, that became locally extinct, and reappeared in later stages. The interpretation of Barrande was questioned in 1854 by Edward Forbes, who pointed to the disturbances, overturns and crumplings in the older rocks as affording a more reasonable explanation of the occurrence of strata with newer fossils amid those containing older ones. Other geologists subsequently questioned the doctrine of “Colonies.” In 1880 Dr J. E. Marr, from a personal study in the field, brought forward evidence to show that the repetitions of the fossiliferous strata on which the “Colonies” were based were due to faults. The later stages of Barrande, F, G and H, have since been shown by Emanuel Friedrich Heinrich Kayser (b. 1845) to be Devonian.

Despite these modifications in the original groupings of the strata, it is recognized that Barrande “made Bohemia classic ground for the study of the oldest fossiliferous formations.” He died at Frohsdorf on the 5th of October 1883.

 BARRANQUILLA, a city and port of Colombia, South America, capital of a province of the same name in the department of Atlantico, on the left bank of the Magdalena river about 7 m. above its mouth and 18 m. by rail from its seaport, Puerto Colombia. Pop. (est. 1902) 31,000. Owing to a dangerous bar at the mouth of the Magdalena the trade of the extensive territory tributary to that river, which is about 60% of that of the entire country, must pass in great part through Barranquilla and its seaport, making it the principal commercial centre of the republic. Savanilla was used as a seaport until about 1890, when shoals caused by drifting sands compelled a removal to Puerto Colombia, a short distance westward, where a steel pier, 4000 ft. in length, has been constructed to facilitate the handling of freight. The navigation of the Magdalena is carried on by means of light-draught steamboats which ascend to Yeguas, 14 m. below Honda, where goods are transhipped by rail to the latter place, and thence by pack animals to Bogotá, or by smaller boats to points farther up the river. Barranquilla was originally founded in 1629, but attracted no attention as a commercial centre until about the middle of the 19th century, when efforts were initiated to secure the trade passing through Cartagena. The city is built on a low plain, is regularly laid out, and has many fine warehouses, public buildings and residences, but its greater part, however, consists of mud-walled cabins supported by bamboo (guadua) framework and thatched with rushes. The water-supply is drawn from the Magdalena, and the city is provided with telephone, electric light and tram services. Owing to periodical inundations, the surrounding country is but little cultivated, and the greater part of the population, which is of the mixed type common to the lowlands of Columbia, is engaged in no settled productive occupation.

 BARRAS, PAUL FRANÇOIS NICOLAS, (1755–1829), member of the French Directory of 1795–1799, was descended from a noble family of Provence, and was born at Fox-Amphoux. At the age of sixteen he entered the regiment of Languedoc as “gentleman cadet,” but embarked for India in 1776. After an adventurous voyage he reached Pondicherry and shared in the defence of that city, which ended in its capitulation to the British on the 18th of October 1778. The garrison being released, Barras returned to France. After taking part in a second expedition to the East Indies in 1782–1783, he left the army and occupied the following years with the frivolities congenial to his class and to his nature. At the outbreak of the Revolution in 1789, he espoused the democratic cause, and became one of the administrators of the department of the Var. In June 1792 he took his seat in the high national court at Orleans; and later in that year, on the outbreak of war with the kingdom of Sardinia, he became commissioner to the French army of Italy, and entered the Convention (the third of the national assemblies of France) as a deputy for the department of the Var. In January 1793 he voted with the majority for the death of Louis XVI. Much of his time, however, was spent in missions to the districts of the south-east of France; and in this way he made the acquaintance of Bonaparte at the siege of Toulon. As an example of the incorrectness of the Barras Memoirs we may note that the writer assigned 30,000 men to the royalist defending force, whereas it was less than 12,000; he also sought to minimize the share taken by Bonaparte in the capture of that city.

In 1794 Barras sided with the men who sought to overthrow the Robespierre faction, and their success in the coup d’état of 9 Thermidor (27th of July) brought him almost to the front rank. In the next year, when the Convention was threatened by the malcontent National Guards of Paris, it appointed Barras to command the troops engaged in its defence. His nomination of Bonaparte as one of his subalterns led to the adoption of vigorous measures, which ensured the dispersion of the royalists and
