Argentine Republic. State of S. America, including the s. part of the continent e. of the summit of the Andes. Its area is 1.200,000 sq. m. The w. part consists of the Andes with their foothills; the remainder of broad plains, partially timbered in the north, becoming more arid and grass-covered in the middle (the pampas region) and sterile in the s. portion, or what was formerly Patagonia. The most important industry is the raising of cattle and sheep, and the principal commerce is in their products. Railroad building is very active; in 1892 there were ab. 7,000 miles in operation. The capital is Buenos Ayres, on the La Plata, founded 1535, pop. 550,000. Other important cities are Cordova, Rosario, and La Plata. Pop. ab. 3,500,000, including nearly 600,000 of European birth.
The region about the mouth of the Rio de la Plata was first explored 1512. The country was dependent on the Government of Paraguay till 1620, when Buenos Ayres became the seat of government, but still subject to the vice-royalty of Peru. In
1809–10 the people renounced their allegiance to Spain, and in 1813 a Congress was assembled at Buenos Ayres, with Povadas as dictator. In 1825 a Constitution was adopted and a federation formed. A war with Brazil for the possession of the region lying between the two resulted in a treaty, 1828, by wiich Uruguay became independent. Other wars ended, 1852, in Rosas' defeat and the independence of Paraguay. A financial crisis in 1890–91, with the repudiation of the public debt, caused the failure of Baring Bros. in London and heavy losses in Europe.

It had its origin ab. 1650, and in the operatic form of the 18th century was thus classified: Aria cantabile, a flowing melody lightly acceompanied; Aria di portamento, in a sustained style; Aria di mezzo carattere, more fully developed and embellished: Aria parlante, Aria di nota e parola, Aria agitato, Aria di strepito, or Aria infuriata, charged with more passionate emotion; Aria di bravura, or Aria d'agilità, florid and designed to display the singer's skill.

In 335 he returned to Athens, where he established the Peripatetic, school, of philosophy and wrote the works now extant. On the death of Alexander, with whose cause he was identified, he fled from Athens, and died shortly afterward in Chalcis. - His writings were long lost: those now attributed to him were pub. about 50 B.C.. They exercised a great influence on the Arabic and Scholastic philosophy, and are regarded as the most important contributions, ever made to philosophy and science. They cover nearly the whole field of knowledge, and make ad; vances in every department. The Organum develops formal logic much as it is now taught; and contaios in ortant discussión of scientific method and of dialectic. The Rhetoric and the fragment On Poetry contain, many acute observations on human nature and conduct, which are elaborated with greater thoroughness and insight in the Ethics. In the Poletics both the idol state and the actual political condition of Greece are discussed. In his writings on metaphysics, psychology, and science, he treats both the most abstruse problems of philosophy and an immense range of special facts. Physical and natural science may be regarded almost as his creation. Aristotle's Lantern. System of teeth guarding the mouth of Sea-urchins.

Egyptian monuments show figures evidently using their hands for counting. The Roman numerals were used in Europe until the 15th century. Our present notation is of Hindoo origin, derived through the Arabs. Traces of it are found in Aryabhatta, an ear Hindoo writer. With the nine digits and zero to denote position, an indefinite range is obtained. The basic notions of reckoning are addition and subtraction: then multiplication and division: still further involution and evolution. Fractions with their decimal notation, the processes of percentage, the progressions and analysis complete the subdivisions of the subject. . Much has been written on the “Theory of Numbers” and their relations when combined.
Arithmetical Complement of a Logarithm. Remainder found by subtracting the logarithm from 10; used in computations by common logarithms to compact addition and subtraction of logarithms into one operation, 10 being subtracted from the sum for each complement used to obtain the required result.
Arithmetical Mean. Half sum of two magnitudes.
Arithmetical Progression. Series whose terms increase or decrease by a constant difference. Analysis of the series shows that any term equals the first term increased by the constant difference multiplied by the number of terms less one: if m =number of terms: a, the first term; d, the difference; and an the last of the n terms, an = a + (n—1) d. (1). The sum of the n terms equals the sum of the first term and last term multiplied by + the number of terms.
n xn = 3 (a + an) (2). Equations (1) and (2)—three elements being known, will solve algebraically all questions in Arithmetical Progression. Arius, 256–336. Heresiarch: Alexandrian presbyter of much ability and learning.

The n. e. part, including nearly half its area, consists of an arid plateau, having a mean elevation of from 6,000 to 7,000 ft., in which the Colorado River has cut its stupendous series of canons. The s. w. part is ...'...}} low, ranging from near sea level up to 2,000 ft., the limits of the high plateau being sharply outlined in most places by an abrupt descent. This lower region is composed of desert plains and valleys, intersected by narrow, sharp mountain ranges. The climate is extremely hot and arid, and agriculture is impossible anywhere without the aid of irrigation. The industries consist mainly of gold and silver mining, with a little agriculture and sheepraising. The capital is Prescott.

Arkansas. One of the s. w. States. Its area is 58,850 sq.m. The n. w. part, including nearly half, its area, is broken and hilly, in some places rising to mountains of 2,500 to 2,800 st., consisting of ridges with e. and w: trend, forming part of the Ozark hill region. The e. part is low and mainly alluvial, and large areas are subject to overflow in time of flood. The principal streams are the Mississippi, Arkansas, White and Washita. The Ozark hill region is composed of carboniferous beds, the hills and mountains being of sandstone. The s. portion is mainly composed of Eocene beds, except the alluvial tracts, which are Quaternary. The dominating industry is agriculture, and chiefly the raising of cotton. In 1890 the value of farm products was ab. $88,000,000. The cotton crop of 1891 was 830,000 bales. The State is covered with magnificent forests, and the cutting and manufacture of lumber is an industry of large and growing importance. Its railroads in 1891 had a total length of 2,287 m. The capital is Little Rock, on
