Rhodium
one of the rare metals white, and brittle, and, with the exception of iridium, one of the most infusible of metals. When pure , it is insoluble in acids, but when alloyed with platinum, bismuth, or copper, it is dissolved with them in aqua regia. Heated in contact with chloride of sodium in a current of chlorine, the double chloride of rhodium and sodium is formed. The only use to form the nibs of metallic pens. Rhodium which rhodium has been applied, is to associated in small quantity with native was discovered by Wollaston in 1803, platinum. and shrubs of the natural order Eri-

Rhoecus
I am the Dryad of this tree And with it I am doomed to live and die. The rain and sunshine are my caterers, Nor have I other bliss than simple life, Now ask me what thou wilt, that I can give And with a thankful joy, it shall be thine. . . . Oh, Rhoecus! nevermore Shalt thou behold me or by day or night, 'Tis thou art blind, Not I unmerciful, I can forgive, But have no skill to heal the spirit eyes.

Rhoecus
re'kus, in Greek legend, a youth who once propped up an oak tree which he saw about to fall. The nymph or dryad of the tree was grateful for the respect thus shown her, and when Rhoecus sought her favor she was very gracious. She charged him, however, to keep faith with her, and that when she sent her messenger, the bee, to summon him he must at once obey. Rhoecus promised to do so. One day, however, the bee came when he was playing checkers, and in his absorption he brushed it hastily away. The dryad was offended, and blinded Rhoecus in consequence. Lowell has made this story the subject of a poem entitled Rhoecus.

Rhomb
or RHOMBUS, in geometry, an oblique parallelogram whose sides are all equal. The diagonals of a rhombus bisect each other at right angles. The area of a rhombus is equal to half the product of its diagonals. Fresnel's rhomb, in optics, is an apparatus for converting plane into circularly polarized light. It is a parallelopiped of glass, of such length and angles that a ray of light entering one small end at right angles, twice suffers total reflection within the rhomb at an angle of about 54° (depending on the polarizing angle of the glass), and finally emerges at right angles from the opposite small end. When the beam of light is plane polarized, and the rhomb is so arranged that its reflecting faces are inclined at an angle of 45° to the plane of polarization, the beam emerges circularly polarized.

Rhubarb
ru'barb, a heavy-leafed relative of the dock, sheep sorrel, buckwheat, and smartweed. The similarity may be noticed in juice and seed. Common rhubarb is thought to be a native of southern Siberia. The clustered root-stocks are dried for the druggist; the leaf-stalks are the famous "pieplant" of American markets. There is very little sentiment connected with pieplant, but it is a substantial addition nevertheless to the kitchen garden. Gardeners vie with each other in producing mammoth tender stems by banking the growing plant. Medicinal rhubarb

Rhyme
more correctly RIME, in poetry, a correspondence in sound of the ng word or syllable of one line terminating of poetry with the terminating word or syllable of another. To constitute this correspondence in single words or in syllables it is necessary that the vowel and the final consonantal sound (if any) should be the same, or have nearly the same sound, the initial consonants being different. If the rhyme is only in the last syllables, as in forgave and behave, it is called a single rhyme; if in the two last syllables, as bitter and glitter, it is called a double rhyme; if in the last three syllables, as callosity and reciprocity, it is called a triple rhyme. Rhymes which extend to more than three syl lables are almost confined to the Arabians and Persians in their short odes (gazelles), in which the same rhyme, carried through the whole poem, extends sometimes to four and more syllables. The modern use of rhymes was not known to the Greeks and Romans; though some rhymed verses occur in Ovid. It has been used, on the other hand, from time immemorial among the Chinese, Hindus, Arabs, and other Oriental nations. Rhyme began to be developed among the western nations in the Latin poetry of the Christian Church. It is found used as early as the 4th century. The early English, German, and Scandinavian poems are distinguished by alliteration instead of rhymes.

Rhymer
THOMAS, of Erceldoune, or Earlston, Berwickshire, England, otherwise called THOMAS THE RHYMER; a half-legendary Scotch poet or romancer of the 13th century. He is mentioned by Barbour, Blind Harry, and Wyntoun, was credited with prophetical powers, and his "Prophecies," a collection of oracular rhymes, were long popular in Scotch folk lore. The old metrical romance of "Sir Tristram" is doubtfully ascribed to him.

also known as Liparite and Nevadite, a group of volcanic rocks, rocks, containing a high percentage of silica, and possessing in many cases a vitreous character. The name Liparite is derived from the Lipari Islands, where quantities of Rhyolites are found.
