RAYLEIGH, LORD-RAYMOND OF SABUNDE

Mahommedan ruler; all who pay the haraj or poll-tax levied on unbelievers. Five classes of rayahs existed under Turkish rule, -(1) the Greek, or Roum milleti; (2) the Armenian, or Emcni milleti; (3) the Catholic Armenians-eremeni gotoliki milleti; (4) the Latin Christians, or Roum gotoliki milleti;and (5) the Jews, or ichondi milleti. The name rayah is most commonly used of the peasants, but it does not apply only to the agricultural populations. It depended on status, fixed by religious faith.


RAYLEIGH, JOHN WILLIAM STRUTT, 3rd baron (1842-), English physicist, was born in Essex on the 12th of November 1842, being the son of the 2nd baron? Going to Trinity College, Cambridge, he graduated as senior wrangler in 1865, and obtained the first Smith's prize of the year, the second being gained by Professor Alfred Marshall. He married in 1871 a sister of Mr A. ]. Balfour, and succeeded to the title in 1873. From 1879 to 1884 he was Cavendish professor of experimental physics in the university of Cambridge, in succession to Clerk Maxwell; and in 1887 he accepted the post of professor of natural philosophy at the Royal Institution of Great Britain, which he resigned in 1905. His early mathematical and physical papers, written under the name of ]. W. Strutt, made him known over Europe; and his powers rapidly matured until, at the death of Clerk Maxwell, he stood at the head of British physicists, Sir George Stokes and Lord Kelvin alone excepted. The special feature of his work is its extreme accuracy and definiteness; he combines the highest mathematical acumen with refinement of experimental skill, so that the idea of ranking him as higher in one department than another does not arise. His experimental investigations are carried out with plain and usually home-made apparatus, the accessories being crude and rough, but the essentials thoughtfully designed so as to compass in the simplest and most perfect manner the special end in view. A great part of his theoretical work consists in resurveying things supposed superficially to be already known, and elaborating their theory into precision and completeness. In this way he has gone over a great portion of the field of physics, and in many cases has either said the last word for the time being, or else started new and fruitful developments. Possessing an immense range of knowledge, he has hlled up lacunae in nearly every part of physics, by experiment, by calculation, and by clear accurate thought. The following branches have especially felt his influence:-chemical physics, capillarity and viscosity, theory of gases, flow of liquids, photography, optics, colour vision, wave theory, electric and magnetic problems, electrical measurements, elasticity, sound and hydrodynamics. The numerous scientific memoirs in which his original work is set forth were collected under his own editorship in four large volumes, the last of which was published in 1903. His most extensive single work is a book on Sound, which, in the second edition, has become a treatise on vibrations in general. His familiarity with the methods of mathematical analysis and a certain refinement of taste in their application have resulted in great beauty of form. His papers are often difficult to read, but never diffuse or tedious; his mathematical treatment is never needlessly abstruse, for when his analysis is complicated it is only so because the subject-matter is complicated. Of discoveries superficially sensational there are few or none to record, and the weight of his work is for the most part to be appreciated only by professed physicists. One remarkable discovery, however, of general interest, was the outcome of a long series of delicate weightings and minute experimental care in the determination of the relative density of nitrogen gas-undertaken in order to determine the atomic weight of nitrogen-namely, the discovery of argon, the first of a series of new substances, chemically inert, which occur, some only in excessively minute quantities, as constituents of the 1 The barony was created at George IV.'s Coronation in 1821 for the wife of Joseph Holden Strutt, M.P. for Maldon (1790-1826) and Okehampton (1826-1830), who had done great service during the French War as colonel of the Essex militia. He died in 1845, his wife, the baroness, predeceasing him in 1836. Their son (d. 1873) was the 2nd baron.earth's

atmosphere. Lord Rayleigh had an interest in abnormal psychological investigations, and became a member and vice president of the Society for Psychical Research. He was one of the original members of the Order of Merit, instituted in connexion with the coronation of King Edward VII. In 1904 he was awarded a Nobel prize, and at the end of 1905 he became president of the Royal Society, of which he had been elected a fellow in 187 3, and had acted as secretary from 1885 to 1896. He remained president till 1908, in which year he was chosen to succeed the 8th duke of Devonshire as chancellor of Cambridge University.

RAYMOND, HENRY JARVIS (1820-1869), American journalist, was born near the village of Lima, Livingston county, New York, on the 24th of January 1820. He graduated from the university of Vermont in 1840. After assisting Horace Greeley (q.v.) in the conduct of more than one newspaper, Raymond in 1851 formed the firm of Raymond, Jones & Co., and the first issue of the New York Times appeared on the 18th of September 1851; of this journal Raymond was editor and chief proprietor until his death. Raymond was a member of the New York Assembly in 1850 and 1851, and in the latter year was speaker. He supported the views of the radical anti-slavery wing of the Whig party in the North. His nomination over Greeley on the Whig ticket for lieutenant-governor in 1854 led to the dissolution of the famous political “firm” of Seward, Weed and Greeley. Raymond was elected, and served in 1854-56. He took a prominent part in the formation of the Republican party, and drafted the famous “Address to the People” adopted by the Republican convention which met in Pittsburg on the 22nd of February 1856. In 1862 he was again a member, and speaker, of the New York Assembly. During the Civil War he supported Lincoln's policy in general, though deprecating his delays, and he was among the first to urge the adoption of a broad and liberal attitude in dealing with the people of the South. In 1865 he was a delegate to the National Republican Convention, and was made a member, and chairman, of the Republican National Committee. He was a member of the National House of Representatives in 1865-67, and, on the 22nd of December 1865 he ably attacked Thaddeus Stevens's theory of the “dead” states, and, agreeing with the President, argued that the states were never out of the Union, inasmuch as the ordinances of secession were null. In consequence of this, of his prominence in the Loyalist (or National Union) Convention at Philadelphia in August 1866, and of his authorship of the “Address and Declaration of Principles,” issued by the convention, he lost favour with his party. He was removed from the chairmanship of the Republican National Committee in 1866, and in 1867 his nomination as minister to Austria, which he had already refused, was rejected by the Senate. He retired from public life in 1867 and devoted his time to newspaper work until his death in New York city on the 18th of June 1869. Raymond was an able and polished public speaker; one of his best known speeches was a greeting to Kossuth, whose cause he warmly defended. But his great work was in elevating the style and general tone of American journalism. He published several books, including a biography of President Lincoln—The Life and Public Services of Abraham Lincoln (1865), which in substance originally appeared as A History of the Administration of President Lincoln (1864).

RAYMOND OF SABUNDE, or Sabiende (fl. 1434), Spanish scholar, was a teacher of medicine and philosophy and finally regius professor of theology at Toulouse. His Liber noturae sive creaturarnm, f9°c. (written 1454-36), marks an important stage in the history of Natural Theology. The book was directed against the position then generally held, that reason and faith,
