 following year he seems to have been eponymous ephor (Xen. Hell. ii. 3, 10), and in 429 he was sent out as one of the three commissioners ( ) to advise the admiral Cnemus. As trierarch he distinguished himself in the assault on the Athenian position at Pylos, during which he was severely wounded (Thuc. iv. 11. 12).

In the next year, while Brasidas mustered a force at Corinth for a campaign in Thrace, he frustrated an Athenian attack on Megara (Thuc. iv. 70-73), and immediately afterwards marched through Thessaly at the head of 700 helots and 1000 Peloponnesian mercenaries to join the Macedonian king Perdiccas. Refusing to be made a tool for the furtherance of Perdiccas’s ambitions, Brasidas set about the accomplishment of his main object, and, partly by the rapidity and boldness of his movements, partly by his personal charm and the moderation of his demands, succeeded during the course of the winter in winning over the important cities of Acanthus, Stagirus, Amphipolis and Torone as well as a number of minor towns. An attack on Eion was foiled by the arrival of Thucydides, the historian, at the head of an Athenian squadron. In the spring of 423 a truce was concluded between Athens and Sparta, but its operation was at once imperilled by Brasidas’s refusal to give up Scione, which, the Athenian partisans declared, revolted two days after the truce began, and by his occupation of Mende shortly afterwards. An Athenian fleet under Nicias and Nicostratus recovered Mende and blockaded Scione, which fell two years later (421 ). Meanwhile Brasidas joined Perdiccas in a campaign against Arrhabaeus, king of the Lyncesti, who was severely defeated. On the approach of a body of Illyrians, who, though summoned by Perdiccas, unexpectedly declared for Arrhabaeus, the Macedonians fled, and Brasidas’s force was rescued from a critical position only by his coolness and ability. This brought to a head the quarrel between Brasidas and Perdiccas, who promptly concluded a treaty with Athens, of which some fragments have survived (I.G. i. 42).

In April 422 the truce with Sparta expired, and in the same summer Cleon was despatched to Thrace, where he stormed Torone and Galepsus and prepared for an attack on Amphipolis. But a carelessly conducted reconnaissance gave Brasidas the opportunity for a vigorous and successful sally. The Athenian army was routed with a loss of 600 men and Cleon was slain. On the Spartan side only seven men are said to have fallen, but amongst them was Brasidas. He was buried at Amphipolis with impressive pomp, and for the future was regarded as the founder ( ) of the city and honoured with yearly games and sacrifices (Thuc. iv. 78-v. 11). At Sparta a cenotaph was erected in his memory near the tombs of Pausanias and Leonidas, and yearly speeches were made and games celebrated in their honour, in which only Spartiates could compete (Paus. in. 14).

Brasidas united in himself the personal courage characteristic of Sparta with those virtues in which the typical Spartan was most signally lacking. He was quick in forming his plans and carried them out without delay or hesitation. With an oratorical power rare amongst the Lacedaemonians he combined a conciliatory manner which everywhere won friends for himself and for Sparta (Thuc. iv. 81).

 BRASS, a river, town and district of southern Nigeria, British West Africa. The Brass river is one of the deltaic branches of the Niger, lying east of the Rio Nun or main channel of the river. From the point of divergence from the main stream to the sea the Brass has a course of about 100 m., its mouth being in 6° 20′ E., 4° 35′ N. Brass town is a flourishing trading settlement at the mouth of the river. It is the headquarters of a district commissioner and the seat of a native court. Its most conspicuous building is a fine church, the gift of a native chief. The capital of the Brass tribes is Nimbé, 30 m. up river.

The Brass river, called by its Portuguese discoverers the Rio Bento, is said to have received its English name from the brass rods and other brass utensils imported by the early traders in exchange for palm-oil and slaves. The Brass natives, of the pure negro type, were noted for their savage character. In 1856 their chiefs concluded a treaty with Great Britain agreeing to give up the slave-trade in exchange for a duty on the palm-oil exported. Finding their profitable business as middlemen between the up-river producer and the exporter threatened by the appearance of European traders, they made ineffective complaints to the British authorities. The establishment of the Royal Niger Company led to further loss of trade, and on the 29th of January 1895 the natives attacked and sacked the company’s station at Akassa on the Rio Nun, over forty prisoners being killed and eaten as a sacrifice to the fetish gods. In the following month a punitive expedition partially destroyed Nimbé, and a heavy fine was paid by the Brass chiefs. Since then the country has settled down under British administration. The trade regulations of which complaint had been made were removed in 1900 on the establishment of the protectorate of Southern Nigeria (see ).

 BRASS (O. Eng. braes), an alloy consisting mainly if not exclusively of copper and zinc; in its older use the term was applied rather to alloys of copper and tin, now known as (q.v.) Thus the brass of the Bible was probably bronze, and so also was much of the brass of later times, until the distinction between zinc and tin became clearly recognized. The Latin word aes signifies either pure copper or bronze, not brass, but the Romans comprehended a brass compound of copper and zinc under the term orichalcum or aurichalcum, into which Pliny states that copper was converted by the aid of cadmia (a mineral of zinc).

In England there is good evidence of the manufacture of brass with zinc at the end of the 16th century, for Queen Elizabeth by patent granted to William Humfrey and Christopher Schutz the exclusive right of working calamine and making brass. This right subsequently devolved upon a body called the “Governors, Assistants and Societies of the City of London of and for the Mineral and Battery Works,” which continued to exercise its functions down to the year 1710.

When a small percentage of zinc is present, the colour of brass is reddish, as in tombac or red brass, which contains about 10%. With about 20% the colour becomes more yellow, and a series of metals is obtained which simulate gold more or less closely; such are Dutch metal, Mannheim gold, similor and pinchbeck, the last deriving its name from a London clockmaker, Christopher Pinchbeck, who invented it in 1732. Ordinary brass contains about 30% of zinc, and when 40% is present, as in Muntz, yellow or patent metal (invented by G. F. Muntz in 1832), the colour becomes a full yellow. When the proportion of zinc is largely increased the colour becomes silver-white and finally grey. The limit of elasticity increases with the percentage of zinc, as also does the amount of elongation before fracture, the maximum occurring with 30%. The tenacity increases with the proportion of zinc up to a maximum with 45%; then it decreases rapidly, and with 50% the metals are fragile. By varying the proportion between 30 and 43% a series of alloys may be prepared presenting very varied properties. The most malleable of the series has an elongation of about 60%, with a tensile strength of 17.5 tons per sq. in. Increase in the proportion of zinc gives higher tensile strength, accompanied, however, by a smaller percentage of elongation and a materially increased tendency to produce unsound castings. The quality of copper-zinc alloys is improved by the addition of a small quantity of iron, a fact of which advantage is taken in the production of Aich’s metal and delta metal. Of the latter there are several varieties, modified in composition to suit different purposes. Some of them possess high tensile strength and ductility. They are remarkably resistant to corrosion by sea-water, and are well suited for screw-propellers as well as for pump-plungers, pistons and glands. Heated to a dull red delta metal becomes malleable
