Scutes (OF Snakes). Broad scales on the head and ventral surface of snakes. The labials line the margins of the jaws. The most anterior on the upper jaw is the rostral: this is followed in the median line by the anterior and posterior nasals, and the frontal, flanked on each side by the supra-ciliary; next come the parietals, and finally the many small occipitals. Between this series and the labials there are on each side the nasals, loreal, prasorbitals, postorbitals, temporals, and occipitals. Behind the chin scute come the anterior labials, then a double series of mental scutes, followed by the small cervicals, and finally the ventrals under the belly.

Sea. The sea covers 137.200,000 sq. m. of the 192.200.000 sq. m. comprising the earth's surface, or nearly three-fourths. Its mean depth is 12,480 ft. It is separated by land bodies into four great divisions, the Pacific (area 67,500,000 sq. m.), Atlantic (area 36.OCO.000 sq. m.), the Indian (area 28,700,000 sq. m.), and the Arctic oceans (area 5,000,000 sq. m.). A fifth division is sometimes added, comprising the southern parts of the first three, and known as the Southern or Antarctic Ocean. The differential action of the sun's heat upon the surface water of the sea produces currents, which, modified in direction by the earth's rotation and by the land outline, keep up a constant circulation. The specific gravity is ab. 1.027, being greater than that of pure water, owing to the salts held in solution. The surface temperature is at the equator ab 80° F., in the Polar legions ab.28° F. In confined bodies near the equator it rises higher. At great depths it falls to 35" F., and is nearly constant in all latitudes. See Ocean.

Sealed Orders. In the navy, orders given to the commanding officer which are not to be opened until the ship has put to sea.

Sea-Lettuce. Various large light-green seaweeds of the genus Ulva.

Sea Level. Mean height of the surface of the sea when tranquil. If we suppose a canal cut across a continent deep enough for the waters of the ocean to enter and fill it, the surface would mark the sea level along its line. This surface, either of our supposed canal or of mid-ocean, does not of necessity conform to that of an ellipsoid, for in consequence of want of homogeneity of the earth, and of the attractions of continental masses, the waters are in a manner heaped up where the attraction is greatest and depressed where it is least. Thus the mean surface in mid-ocean is believed to be many feet lower than along the shores of the great continents. This difference cannot be determined instrumentality, for the instruments are affected in precisely the same manner as the surface of ocean.

Sealing-Wax. The Hindus from time immemorial were accustomed to use Lac (q.v.) for sealing manuscripts. A good sealing wax is made by melting together 48 parts of shellac. 12 of Venice turpentine, 1 of Peru balsam and 36 of vermilion. The introduction of gummpd envelopes has, to a great extent, superseded the use of sealing-wax.

Sea-Lion. Breeding places and habits are much like those of fur seals. They are larger than the latter, and have only coarse hair as a covering-. The male sea-lion of the n. Pacific (Enmetnjnas stelleri) attains a length of 14 ft. and wt. of 1.000 lbs.; the female is much smaller. They are invaluable to the subsistence of the Aleuts, who drive them overland to their

villages, where they are slaughtered at leisure. The sea-lion most common off San Francisco is Zalophwt. 9 ft. long. Other

Sea-Serpents. Those now existing belong to the family Hydrophidje (q.v.), but those of the cretaceous period, the Pythonomorpha (q.v.), realized the wildest imaginings of those who in modern times report having seen sea-serpents of unknown length and undescribed species. They were true air breathers. Some scientists think it possible that monstrous serpent-shaped fish may exist at great depths in the ocean, and possibly visit the surface at times.

SECONDARIES—SECULAR PERTURBATIONS

Secondaries. Quill-feathers (remiges) borne on the antebrachium (middle joint or section) of the bird's wing.

Secondary. In early geological science, all then known fossiliferous rocks; later, all strata containing extinct species of plants and animals; now nearly equivalent to Mesozoic.

Secondary, or Secondary Cyclones. Small barometric depressions, usually marked by local rains or thunderstorms, and producing minor irregularities in the course of the general isobars.

Secondary Alcohols. Derived from methyl alcohol, CH,.OH, by replacing two hydrogen atoms with two hydrocarbon radicals. Upon oxidation they yield a ketone, and then an acid or acids containing a smaller number of carbon atoms. They do not yield aldehydes. Example, secondary butyl alcohol: CH,.CaH5.CHOH.

Secondary Battery. See Accumulator and Storage Battery.

Secondary Coll. See Inductoiuum.

Secondary Compounds. Formed by replacing hydro

gen in a CH, group by a group or radical. Thus from propane, Hs.CHj.CH,, secondary propyl alcohol, CH3.CHOH.CH3, is derived.

Secondary Generator. See Transformer and ConVerter (electric).

Secondary Roots. Those other than the Primary Root (q.v.), appearing on various portions of the plant, as the climbing roots of the Ivy and Poison Vine, etc.

Secondary Sexual Characters. Any characteristics (as color markings, etc.), except those of the reproductive organs themselves, which distinguish males and females. An example is the spurs present on male fowl.

Seconds Pendulum. See Pendulum.

Secret, Discipline Of The. See Arcani Disciplina.

Secretaries Of State, War. Etc.. Of U.S. These officials are appointed by the President and confirmed by the Senate. The salary of the office is $8,000 per annum. See Cabinet.

Secretary-Bird (serpentarius). S. African, raptorial bird, with long legs (especially the tarsal portion), rather long neck and wings, and the two middle tail feathers much elongated. The back of the head bears a plume of backwardly

[graphic][merged small]

glands, as their normal function; also, the substance so produced.

Secret Nailing. Boards so laid and nailed that the heads of the nails cannot be seen; also called blind nailing.

Secret Service moneys. In England, funds placed at the disposal of the Ministers of State, to be expended at their discretion, without giving an account.

Secret Writing. See Cryptography.

Section. In Architecture, an actual or imagined representation of a building or part of a building as it would appear if cut through at a certain line of the plan so as to expose its interior arrangement and construction. In important and complicated buildings, it is customary to prepare two drawings of vertical sections, one on the longer axis, called the longitudinal, and another at right angle to it, called the transverse section.

Section. Portion of surface included within lines of intersection with other surfaces. A plane section is formed by a plane cutting a surface.

Sectional Boilers. Form in which the generating elements are small and separate units, connecting together into one chamber, from which the outlets take off the steam. The units are spherical in cast-iron boilers, and of lap-welded tube in wrought-iron types. These boilers are portable when transportation is lacking for great weights; an accident to one part does not usually entail loss of the whole structure nor so appalling a disaster, since the water escapes gradually through a small outlet, and repair to the damaged part makes the whole boiler as good as before. The small diameters of the units insure quick transfer of heat through the thinner metal possible, whence the boilers are also light. The difficulties come from leakage of the increased joint area, from unequal expansion of different parts, and from insufficient dis- Sectional Boiler,

engagement area for steam from the water, whence wet steam and overheated metal will result, since the circulation will not be normal. In bad waters, also, scale will deposit in inconvenient places in such boilers. A sectional boiler is successful in proportion as it avoids or diminishes these difficulties. See Boilers.

Sector, PLANE. Portion of plane surface bounded by an arc and the two radii or radii vectors at its extremities. Its revolution about the axis of the curve produces a solid sector.

Secular Acceleration Of The Moon's Mean Motion. Halley found, by comparing the ancient records of eclipses with those observed in the Middle Ages, and these in turn with modern observations, that a change was going on in the moon's velocity. This has since been shown to be due to the change in the eccentricity of the earth's orbit, and possibly in part to a lengthening of the day.

Secular Games. Supposed to be celebrated in Rome at the commencement of each Sajculum or period. From 249 B.C., a law made them obligatory every 100 years; but Augustus had this changed to 110 years. Horace wrote the Carmen Soeculare for this celebration, as is recorded upon a tablet discovered recently in Rome.

Secularism. Humanitarian scheme devised in London 1844, and pushed by local and national societies, led by 6. J. Holyoake and later by C. Bradlaugh. It aimed at ethical and social improvement, on temporal grounds, and in a spirit essentially democratic and anti-theological.

Secularization. Conversion of Ch. property to other uses, as in England under Henry VIII.. and later in France, Italy, and other countries; also transfer of authority, as over education and ma.'riage, from Ch. to State.

Secular Perturbations Of Comets And Planets. Such as go on for ages in the same direction; distinguished from periodic, which complete their cycle in the course of a fewyears at most.

Seed-Bagging. Method of introducing and establishing a water-tight packing at any desired point in an artesian-, salt-, or oil-well, between the central tubing and the rock wall, by means of a strong bag fastened to the outside of the tube and filled with flaxsend.
