CECIL, RICHARD, clergyman; born in London, Nov. 8, 1748; died at Tunbridge Wells, Aug. 15, 1810. He was ordained a minister of the Church of England in 1776; minister at St. John's, London, and Risley in Surrey. He wrote a series of biographies, which include some of Rev. John Newton; a series of miscellaneous tracts; a volume of sermons; and a volume of Remains, a work eminently useful to ministers.

CECROPIA, a South American and West Indian genus of Urticaceæ, known as "trumpet-trees.' The pith is divided into chambers, and these partitions being removed, the branches are made into water-pipes and wind-instruments. The wood is very light, and is used to make floats for nets, and by the Indians in kindling fires, by friction against a harder piece of wood. The bast yields a cordage fiber, and the outer bark is astringent. The fruit resembles a raspberry, the buds furnish a potherb and the juice hardens into caoutchouc. The pith-chambers are inhabited by ants, which feed upon small food-bodies formed on the leafpetioles, and serve as a police-protection against dangerous ants and other insects. The leaves are a favorite food of the sloth.

above the north fork. He himself had been called to Washington, and had left General Wright in command. During the previous night the Confederates had marched around and taken their position behind and to the left of the Union line. Part of the Union troops were routed, the rest General Wright withdrew about a mile to the north, taking up a more favorable position. The Confederates followed, though in disorder, and formed again in front of General Wright's line. At this time, a little before one p.m., Sheridan, who had heard of the battle, at Winchester, arrived, and his appearance inspired his men with confidence, so that they drove back the enemy. General Sheridan then prepared for aggressive action, and about four p. m. made a spirited attack, driving the Confederates completely from the field, and recapturing all the guns and ammunition which had been lost on the previous night, and capturing, in addition, 24 guns and 56 ambulances from the enemy. The Union losses in killed, wounded and prisoners was estimated at 6,000. The Confederates lost about 3,100. This was the last important battle in the Shenandoah valley. It was this ride of Sheridan's, from Winchester to Cedar Creek, that forms the theme of Thomas Buchanan Read's famous poem.

CECROPIA, a moth of the genus Platysamia, | Cedar Rapids and Northern, Chicago Great Westwidely distributed in the United States. The wings are brown, with a red and black crescentlike spot near the center. The young caterpillars are black, but the mature specimens are of a green color. They construct cocoons of very fine silk. In California an attempt is being made to cultivate the cecropia silk-worm.

CEDAR, BASTARD BARBADOS (Cedrela odorata), a tree of the family Meliacea, a native of the tropical parts of America. It is often upward of 80 feet high, with a trunk remarkable for its thickness. The wood has an agreeable fragrance, and, being light and soft, it is used for canoes, shingles and cigar-boxes. In France it is used in making black lead-pencils. True Barbados cedar is Juniper barbadensis, and is of much less importance. The true cedar belongs to the coniferous genus Cedrus (q.v.).

CEDAR-BERG, a mountain range in Cape Colony, stretching north and south on the east side of Olifant River valley, in Clanwilliam division.

CELLULOID OR PARKESINE, a substance. consisting chiefly of a dried solution of guncotton (pyroxylin). A variety of it can be made with. pyroxylin and camphor. It resembles ivory, horn, tortoise-shell and hardened India-rubber. pyroxylin is prepared by treating cellulose from such vegetable materials as cotton, rags, papermaker's half-stuff, or paper itself, with a mixture of one part of strong nitric acid and four parts of strong sulphuric acid. The distillate obtained by distilling wood-naphtha with chlorid of lime is used as a solvent for the pyroxylin. When the excess of solvent is removed from the pyroxylin, it is mixed with a considerable quantity of castoroil or cottonseed-oil, and made into a paste between heated rollers. For a hard compound, the quantity of oil should be less than the pyroxylin. In a plastic condition, celluloid can be spread on textile fabrics, or it may be made as hard as ivory, for which it is largely used as a substitute. Billiard-balls, piano-keys and combs are made of it. It can be colored to represent amber, tortoise-shell or malachite. In imitation of red

changed to glucose by long boiling with dilute sulphuric acid. A substance resembling parchment is readily obtained by treating unsized paper with cold sulphuric acid. Cellulose is also said to exist in the tunics of Ascidia, and in other invertebrates. It is insoluble in water, alcohol, ether, dilute alkalies and dilute acids. It is remarkable for its insolubility, being dissolvable, so far as at present known, only by an ammoniacal solution of oxid of copper, from which it may be again precipitated. It may be bleached by the action of chlorin water. Skeleton leaves, so often made in phantom bouquets, consist of nearly pure cellulose. They are usually prepared either (a) by boiling the leaves in a dilute solution of caustic soda, and bleaching by an immersion in a solution of hypochlorite of lime, or (b) by suspending the leaves in a mixture of nitric acid and chlorate of potassa for several days. It is isomerous, with

starch in its composition, and allied to starch, sugar and inulin. Cotton and bleached flax, as well as hemp, are nearly pure cellulose. With age it becomes largely transformed into lignin, suberin, or mucilage. In some filter-paper, notably the Swedish, it is in almost a chemically pure state. Sugar and gum are nearly allied to it in composition. When pure, it is fibrous or spongy, white, translucent and often silky. Under the microscope the fibrous varieties appear like spun glass. It is tough and extremely elastic, with a specific gravity of 1.5.

By dipping paper or cotton or linen fabrics in a copper-ammonia solution of cellulose, and then passing the sheets between rolls, they are rendered water-proof. Several layers of such sheets of cloth or fiber pressed together form an artificial wood of enormous strength. A plastic mass of this material can be readily prepared, suitable for the manufacture of water-pipes, gas-pipes, hats, clothing, boats, etc.

Cellulose, by reason of its peculiar properties, is being largely introduced into ship-building, as it is specially adapted for resisting blows, concussions, or perforations, either above or below the water-line. Its component parts are carbon, dydrogen and oxygen, and its scientific formula is given as C18H30O15.

In

The material used for ship-protection is usually made from the ground fiber of the cocoanut with a small percentage of original fibers. It is extremely light, and has the property of rapidly swelling when wet. A cubic foot weighs about seven and a half to eight pounds. It is practically free from danger of fire, burning very slowly, and with great difficulty when compressed. France, experiments have been made by firing a ten-inch shot through a mattress of cellulose; the fibers came together and swelled so rapidly that only three and a half gallons per minute of water passed through the aperture, and in a short time the aperture was closed entirely. Cellulose was first used in ship-building in 1884, but so rapidly did it obtain favor that in 1890 the French had introduced it into the construction of some 40 vessels of their navy, and in the same year its use

was ordered as a means of protection in the construction of ships in Russia, Holland, Japan and Greece, as well as in the American navy. Its cost is about $1 a cubic foot, or approaching $250 a ton. (See FIBRES, Vol. IX, pp. 131, 132; BIOLOGY, Vol. III, p. 169; and GUN-COTTON, Vol. XI, p. 277.

CEMETERIES, NATIONAL. There are eightythree cemeteries kept in condition and cared for by the United States government. In such cemeteries are buried soldiers and officers who have died in battle during a war, or who have died while in active service. Special provisions are made at times to provide for the burying there of ex-soldiers who die paupers. These eighty-three national cemeteries are scattered throughout the states of the Union, but are principally near the larger battle-fields of the Civil War, and near United States army posts. They are in charge of the quartermaster's department.

CENTAUREA, a genus of plants of the family Composite, containing numerous species of annual and perennial herbaceous plants, chiefly natives of temperate and cold regions. The corn-bluebottle (C. cyanus), common in flower-gardens, has flowers variously modified by cultivation. The generic name has its origin in an ancient legend concerning the cure of a centaur by one of these species. The genus is related to the thistles, its numerous species (often called "star thistles,'') belonging chiefly to the eastern hemisphere, many of them being cultivated.

CENTRAL FORCES. When a body is once in motion, unless it be acted upon by some force, it will move uniformly forward in a straight line with unchanged velocity. If, therefore, a body moves uniformly in any other path than a straight line-in a circle, for instance--this must be because some force is constantly at work which continuously deviates it from this straight line. If the deviating force acts toward a point, as, for

CENTROSPHERE, in botany, a name applied to a cell-body closely associated with the nucleus. Centrospheres usually occur as a pair of spherical bodies in contact with the nucleus, each of which consists of a small dense central body (centrosome), surrounded by a clear layer, and limited by granular substance. The centrospheres are observed to play an important part in nuclear and cell-division, in consequence of which they are often called "directive spheres"; also called "asters" from the fact that they are centers of radiating lines of structure. Their exact nature and function are still obscure. In fact, it is a question whether the centrosome is not the only essential part, and the rest of the somewhat inde

CENTURY-PLANT, the popular name of Agave Americana, a Mexican plant of the family Amaryllidacea, otherwise known as American aloe. It develops a large cluster of very thick and large spiny leaves, from the midst of which, after a varying number of years, dependent on the climate, a flowering stalk very rapidly rises, attaining a height of 20 to 30 feet, and bearing an enormous cluster of greenish-yellow flowers. After flowering, the plant dies. The popular name arose from the erroneous impression that a century of leafformation and food-storage elapsed before the appearance of the flower-stalk.

*CERAMIC ART.-Its Development in the United States since 1880. Ceramic art, or the department of the plastic and decorative arts which deals with objects made of clay, has been developed to its present degree of excellence in the United States practically within the last twenty years. The chief causes contributing to bring about this rapid advance were the Centennial Exhibition of 1876 and the tariff act of 1883. The former event, with its extensive exhibit of European pottery, opened the eyes of the American manufacturer to his own inferiority, and fired him with the spirit of emulation; the latter, by rendering practicable, commercially, the production of finer wares, gave opportunity for the acquirement of that practice and experience which has since ripened into an established and perfected ceramic art in America. Imitation was the first and most natural characteristic of the attempt to introduce grace and beauty into the homely practice of utilitarian potting. The first effects of this movement were seen in the occasional production of ornamental single pieces, patterned closely upon the famous faience of Limoges, or the oddly shaped, gorgeously decorated wares of Japan, and in a gradual, though marked, refinement in the bodies of the dense and cumbrous stone and earthenwares which had contrasted so clumsily in 1876 with the delicate porcelains and semi-porcelains of Worcester, Doulton and Sèvres.
