**cubic**centimetre (W) was fairly represented by o 00125B 1 6 and o o0101B 1 ' 6 respectively, the maximum induction ranging from about 300 to 3000.In one case the hysteresis loss per

**cubic**centimetre per cycle was 16,100 ergs for B =1 5,900, and only 1200 ergs for B = 20,200, the highest induction obtained in the experiment; possibly it would have vanished before B had reached 21,000.2 These experiments prove that actual friction must be almost entirely absent, and, as Baily remarks, the agreement of the results with the previously suggested deduction affords a strong verification of Ewing's form of the molecular theory.The wood is very heavy and hard, weighing 70 lb the

**cubic**forms with perfect**cubic**cleavage; tetramethyl ammonium iodide is tetragonal with perfect cleavages parallel to {100} and {o01} - a difference due to the lengthening of the a axes; tetraethyl ammonium iodide also assumes tetragonal forms, but does not exhibit the cleavage of the tetramethyl compound; while tetrapropyl ammonium iodide crystallizes in rhombic form.We may therefore regard the nitrogen atoms as occupying the centres of a

**cubic**space lattice composed of iodine atoms, between which the hydrogen atoms are distributed on the tetrahedron face normals.For the

**cubic**(ab) 2 axbx is a covariant because each symbol a, b occurs three times; we can first of all find its real expression as a simultaneous covariant of two cubics, and then, by supposing the two cubics to merge into identity, find the expression of the quadratic covariant, of the single**cubic**, commonly known as the Hessian.AdvertisementFor the quadratic it is the discriminant (ab) 2 and for ax2 the

**cubic**the quadratic covariant (ab) 2 axbx.We will write the

**cubic**pxgxrx is zero, and hence from a property of the covariant j we must have j = pxgxrx; showing that the linear forms involved are the linear factors of j.Hesse showed independently that the general ternary

**cubic**can be reduced, by linear transformation, to the form x3+y3+z3+ 6mxyz, a form which involves 9 independent constants, as should be the case; it must, however, be remarked that the counting of constants is not a sure guide to the existence of a conjectured canonical form.AdvertisementThe closed figure a c d e a is variously called a hysteresis curve or diagram or loop. The area f HdB enclosed by it represents the work done in carrying a

**cubic**foot of wrought iron, strongly magnetized first one way and then the other, the work so expended taking the form of heat in the mass.When the magnetizing current is twice reversed, so as to complete a cycle, the sum of the two deflections, multiplied by a factor depending upon the sectional area of the specimen and upon the constants of the apparatus, gives the hysteresis for a complete cycle in ergs per

**cubic**centimetre.**Cubic**equations were solved geometrically by determining the intersections of conic sections.Archimedes' problem of dividing a sphere by a plane into two segments having a prescribed ratio,was first expressed as a

**cubic**equation by Al Mahani, and the first solution was given by Abu Gafar al Hazin.AdvertisementAlthough the foundations of the geometrical resolution of

**cubic**equations are to be ascribed to the Greeks (for Eutocius assigns to Menaechmus two methods of solving the equation x 3 = a and x 3 = 2a 3), yet the subsequent development by the Arabs must be regarded as one of their most important achievements.This contest over, Tartalea redoubled his attempts to generalize his methods, and by 1541 he possessed the means for solving any form of

**cubic**equation.Cardan or Cardano, who was at that time writing his great work, the Ars Magna, could not restrain the temptation of crowning his treatise with such important discoveries, and in 1 545 he broke his oath and gave to the world Tartalea's rules for solving

**cubic**equations.**Cubic**equations having been solved, biquadratics soon followed suit.The alluvial extracted, which in the Malay Peninsula and Archipelago carries from 5 to 60 lb of tinstone (or "black tin," as it is termed by Cornish miners) to the

**cubic**yard of gravel, is washed in various simple sluicing appliances, by which the lighter clay, sand and stones are removed and tinstone is left behind comparatively pure, containing usually 65 to 75% of metallic tin (chemically pure tinstone contains 78.7%).AdvertisementOf the water received by Albert Nyanza annually (omitting the Victoria Nile from the calculation) between 50 and 60% is lost by evaporation, whilst 24,265,000,000

**cubic**measure are amplified by the insertion of intermediate units.For square measure 12 square inches = I superficial prime, 12 superficial primes = I square foot; while for

**cubic**measure 12**cubic**inches = I solid second, 12 solid seconds = I solid prime, 12 solid primes = I**cubic**foot.The same formula will also hold (Â§ 52) for any

**cubic**trapezette through the points.Although Hippocrates could not determine the proportionals, his statement of the problem in this form was a great advance, for it was perceived that the problem of trisecting an angle was reducible to a similar form which, in the language of algebraic geometry, is to solve geometrically a

**cubic**equation.The kinetic energy per

**cubic**centimetre is 2 pu t, where is the density and u is the velocity of disturbance due to the passage of the wave.AdvertisementHence the work done on the air is (P-+zw)v, and the work done per

**cubic**mineral diamond, but between the two there are very wide differences in physical characters.AdvertisementThe Habra barrage holds 38,000,000

**cubic**metres; that on the Sig 18,000,000.In such definition an attempt has been made to avoid former confusion of expression as to capacity,

**cubic**measure, and volume; the litre being recognized as a measure of capacity holding a given weight of water.Hence a

**cubic**foot of water would weigh 62.281 lb avoir., and not 62.321 lb as at present legally taken.The two standards, the

**cubic**inch and the**cubic**decimetre, may not be strictly comparable owing to a difference in the normal temperature (Centigrade and Fahrenheit scales) of the two units of extension, the metre and the yard.The weight of a

**cubic**decimetre of water reaches 1000 grammes under a pressure of four atmospheres; but in vacuo, at all temperatures, the weight of water is less than a kilogram.AdvertisementTo illustrate how easy it is to go astray in this line, observe the continual reference in modern handbooks to the

**cubic**foot as 1000 oz.Again, there are many theories of the equivalence of different

**cubic**cubits of water with various multiples of talents (2, 3, 18, 24, 33); but connexion by lesser units would be far more probable, as the primary use of weights is not to weigh large cubical vessels of liquid, but rather small portions of precious metals.The Roman amphora being equal to the

**cubic**foot, and containing 80 librae of water, is one of the strongest cases of such relations, being often mentioned by ancient writers.He shows that the length of the cubit arose through the weights; that is to say, the original cubit of Egypt was based on the

**cubic**double -- cubit of water -- and from this the several nations branched off with their measures and weights.It is curious, however, to find that an ancient nation of the East, so wise in geometrical proportions, should have followed what by modern experience may be regarded as an inverse method, that of obtaining a unit of length by deducing it through weights and

**cubic**measure, rather than by deriving**cubic**measure through the unit of length.All quantities stated in this article without distinguishing names are in British units of inch,

**cubic**inch or grain.Beside the equivalence of the hon to 5 utens weight of water, the mathematical papyrus (35) gives 5 besha = (2/3)

**cubic**cubit (Revillout's interpretation of this as 1 cubit cubed is impossible geometrically; see Rev. Eg., 1881, for data); this is very concordant, but it is very unlikely for 3 to be introduced in an Egyptian derivation, and probably therefore only a working equivalent.The Roman theory of the amphora being the

**cubic**foot makes it 1569 cub.Another theory (3) derives the uten from 1/1000 of the

**cubic**cubit of 24 digits, or better of 6/7 of 20.63; that, however, will only fit the very lowest variety of the uten, while there is no evidence of the existence of such a cubit.Though it has no exact relation to the congius or amphora, yet it is closely = 4977 grains, the 1/80th of the

**cubic**foot of water.The galena group includes several other

**cubic**minerals, such as argentite (q.v.).Mention may also be made here of clausthalite (lead selenide, PbSe) and altaite (lead telluride, PbTe), which, with their lead-grey colour and perfect

**cubic**cleavage, closely resemble galena in appearance; these species are named after the localities at which they were originally found, namely, Klausthal in the Harz and the Altai mountains in Asiatic Russia.The compound FeS 2 is dimorphous, and the modern practice is to distinguish the

**cubic**forms as pyrites and the orthorhombic as marcasite (q.v.).Sometimes, however, the term pyrites is loosely applied to both species, and the

**cubic**pyrites is then differentiated by the name "pyrite" - a form which brings the last syllable into harmony with the spelling of the names of most minerals.Iron pyrites, or pyrite, belongs crystallographically to the parallelfaced hemihedral class of the

**cubic**system.Pyrites presents a conchoidal fracture, and a very indistinct

**cubic**cleavage.It crystallizes in the

**cubic**system, usually in cubes, pentagonal dodecahedra or octahedra, often of great beauty and perfection.Crystals belonging to the

**cubic**system should not be birefringent unless strained; diamond often displays double refraction particularly in the neighbourhood of inclusions, both liquid and solid; this is probably due to strain, and the spontaneous explosion of diamonds has often been observed.Carbonado or " black diamond," found in Bahia (also recently in Minas Geraes), is a black material with a minutely crystalline structure somewhat porous, opaque, resembling charcoal in appearance, devoid of cleavage, rather harder than diamond, but of less specific gravity; it sometimes displays a rude

**cubic**crystalline form.The ground is transferred in trucks to the shaft where it is automatically tipped into skips holding 96

**cubic**ft.Graphitic carbon in

**cubic**form (cliftonite) has also been found in certain meteoric " irons," for example in those from Magura in Szepes county, Hungary, and Youndegin near York in Western Australia.Crystals of blende belong to that subclass of the

**cubic**system in which there are six planes of symmetry parallel to the faces of the rhombic dodecahedron and none parallel to the**cubic**faces; in other words, the crystals are**cubic**with inclined hemihedrism, and have no centre of symmetry.It becomes then the duty of the engineer in charge to use every effort to get its full value out of every

**cubic**foot of water.This would increase the storage capacity 22 times, or to about 9,375,000 millions of

**cubic**feet.The method of estimating the area of irregular fields and the

**cubic**contents of granaries, &c., is very faulty.Halite or rock-salt crystallizes in the

**cubic**system, usually in cubes, rarely in octahedra; the cubes being solid, unlike the skeleton-cubes obtained by rapid evaporation of brine.The mineral has perfect

**cubic**cleavage.**Cubic**pseudomorphs representing rock-salt are sometimes seen in strata which have been deposited in shallow water, especially on the margin of a salt-lake.The salt has been dissolved out of its original matrix, and the cavity so formed has then been filled with fine clayey or other mineral matter, forming a

**cubic**cast.In the geometry of plane curves, the term parabola is often used to denote the curves given by the general equation a' n x n = ym+n, thus ax= y 2 is the quadratic or Apollonian parabola; a 2 x = y 3 is the

**cubic**parabola, a 3 x = y4 is the biquadratic parabola; semi parabolas have the general equation ax n-1 = yn, thus ax e = y 3 is the semicubical parabola and ax 3 = y 4 the semibiquadratic parabola.The cartesian parabola is a

**cubic**curve which is also known as the trident of Newton on account of its three-pronged form.John Wallis utilized the intersections of this curve with a right line to solve

**cubic**equations, and Edmund Halley solved sextic equations with the aid of a circle.Diverging parabolas are

**cubic**curves given by the equation y 2 = 3 -f-bx 2 -cx+d.Newton discussed the five forms which arise from the relations of the roots of the

**cubic**equation.The standard of measurement most in use is the St Petersburg standard, which contains 165

**cubic**ft., and the Honduras variety about 36 lb.The average weight of a

**cubic**foot is about 61 lb.The annual timber yield of the Indian forests is about fifty millions of

**cubic**feet, excluding what is used for local purposes.This quantity is now, as the result of further experiments, added to the values of h, and also represented in the formula for the specific heat itself by the

**cubic**term.Even then, however, the amount of operative heat is very small in comparison with that which passes through the steam-engine, per

**cubic**foot swept through by the piston, for the change of state which water undergoes in its transformation into steam involves the taking in of much more heat than can be communicated to air in changing its temperature within such a range as is practicable.Chalcopyrite crystallizes in the tetragonal system with inclined hemihedrism, but the form is so nearly

**cubic**that it was not recognized as tetragonal until accurate measurements were made in 1822.Then the variation of the

**cubic**contents of the vessel in a unit of time by reason of the motion of one piston is Va.It is estimated, however, that the domestic use of wood (especially for fuel) represents nearly five times as many

**cubic**feet as the wood used for export in different shapes.It crystallizes in the

**cubic**system, but the crystals are often flattened, elongated, rounded or otherwise distorted.Immense quantities are still exported, especially from Canada, its smooth easily-worked grain rendering it a favourite wood for the housecarpenter and joiner; it weighs about 28 lb per

**cubic**foot.More important, however, are the supplies to be derived from the control of flood water, millions of

**cubic**feet of the best soil being annually washed into the sea.In the case of diphtheria the antitoxic power of the serum may reach Boo units per

**cubic**centimetre, or even more.Fluor-spar, though

**cubic**, sometimes exhibits weak double refraction, probably due to internal tension.The simple "syrup" of the British Pharmacopoeia is prepared by adding 1000 grams (or 5 lb) of refined sugar to 500

**cubic**centimetres (or two pints) of boiling distilled water, heating until it is dissolved and subsequently adding boiling distilled water until the weight of the whole is 1500 grams (or 71 lb).Silver sulphide, Ag 2 S, occurs naturally as the orthorhombic acanthite, and the

**cubic**argentite; the telluride, Ag 2 Te, named hessite, assumes**cubic**forms; other tellurides containing silver are petzite, (Ag,Au) 2 Te, and sylvanite, AuAgTe 4.Among his most remarkable works may be mentioned his ten memoirs on quantics, commenced in 1854 and completed in 1878; his creation of the theory of matrices; his researches on the theory of groups; his memoir on abstract geometry, a subject which he created; his introduction into geometry of the "absolute"; his researches on the higher singularities of curves and surfaces; the classification of

**cubic**curves; additions to the theories of rational transformation and correspondence; the theory of the twenty-seven lines that lie on a**cubic**surface; the theory of elliptic functions; the attraction of ellipsoids; the British Association Reports, 1857 and 1862, on recent progress in general and special theoretical dynamics, and on the secular acceleration of the moon's mean motion.This average has decreased with some regularity from a maximum of 5.75 in 1821, but there is no certain evidence on which to affirm or deny that the average

**cubic**capacity of dwelling-houses has been maintained.He was professor of mathematics in the university of Deseret and wrote several books on this subject, these including

**Cubic**and Biquadratic Equations (1866).It has been calculated that the average daily discharge of the Muir in summer is 30,000,000

**cubic**ft.Ladoga discharges its surplus water by means of the Neva, which flows from its south-western corner into the Gulf of Finland, rolling down its broad channel 104,000

**cubic**ft.In the first volume Of the Entwickelungen he applied the method of abridged notation to the straight line, circle and conic sections, and he subsequently used it with great effect in many of his researches, notably in his theory of

**cubic**curves.The capacity of the cranium is estimated in

**cubic**measure by filling it with sand, &c., with the general result that the civilized white man is found to have a larger brain than the barbarian or savage.Some of the valleys are of considerable width; in other cases the opposite walls of the gorges are but two or three hundred yards apart, and fall almost vertically thousands of feet, representing an erosion of hard rock of many millions of

**cubic**feet.The discharge of the lake is computed to be 75,200

**cubic**ft.The cost of buildings of the same class and finish is in direct proportion to their

**cubic**contents, and each**cubic**foot constructed is commercially unprofitable which does not do its part in paying interest on the capital invested.Although, like the other streams which cross the Karroo, the river is sometimes dry in its upper course, it has an estimated annual discharge of 51,724,000,000

**cubic**ft.Mountain areas of io,000 acres and upwards, largely covered with moorland, upon nearly imper meable rocks with few water-bearing fissures, yield in temperate climates, towards the end of the driest seasons, and therefore solely from underground, between a fifth and .a quarter of a

**cubic**foot per second per 1000 acres.Thus, for example, on woo acres or less, it commonly falls to onetenth of a

**cubic**foot, and upon an upland Silurian area of 940 acres, giving no visible sign of any peculiarity, the discharge fell, on the 21st of September 1893, to one-thirty-fifth of a**cubic**foot per second per woo acres.The Thames at Teddington, fed largely from cretaceous areas, fell during ten days in September 1898 (the artificial abstractions for the supply of London being added) to about one-sixth of a

**cubic**foot, and since 1880 the discharge has occasionally fallen, in each of six other cases, to about one-fifth of a**cubic**foot per second per woo acres.We have seen that the average flow from mountain areas in Great Britain towards the end of a dry season does not exceed one-fifth of a

**cubic**foot per second per 1000 acres.In Wales it is usually about one-fourth, and elsewhere still less; but in any case it amounts to many times the above unit of one-fifth of a

**cubic**foot per second per 1000 acres.The diagram applies to ordinary areas suitable for reservoir construction and in which the minimum flow of the stream reaches about one-fifth of a

**cubic**foot per second per moo acres.The average volume in dry weather, of such flow, generally reduced to terms of the fraction of a

**cubic**foot per second, per thousand acres of the contributing area, is commonly known in water engineering as the " dry weather flow " and its volume at the end of the dry season as the " extreme dry weather flow."In nearly all cases several of these chambers are connected so as to form a set of a

**cubic**capacity of from 100,000 to 200,000 cub.Murray estimates the total land area draining to the Indian Ocean at 5,050,000 geographical square miles, almost the same as that draining to the Pacific. The annual rainfall draining from this area is estimated at 4380

**cubic**miles.The litre is equal to a

**cubic**decimetre.The gramme was intended to be equal to the weight of a

**cubic**centimetre of pure water at a certain temperature, but the equality is only approximate.Below the mouth of the Tambopata, the flow is estimated at 191,250

**cubic**metres per minute.A curve of the third order is called a

**cubic**; one of the fourth order a quartic; and so on.Various properties of curves in general, and of

**cubic**curves, are established in Colin Maclaurin's memoir, "De linearum geometricarum proprietatibus generalibus Tractatus " (posthumous, say 1746, published in the 6th edition of his Algebra).We have in it a particular kind of correspondence of two points on a

**cubic**curve, viz.By means of Pliicker's equations we may form a table - The table is arranged according to the value of in; and we have m=o, n= r, the point; m =1, n =o, the line; m=2, n=2, the conic; of m = 3, the

**cubic**, there are three cases, the class being 6, 4 or 3, according as the curve is without singularities, or as it has 1 node or r cusp; and so of m =4, the quartic, there are ten cases, where observe that in two of them the class is = 6, - the reduction of class arising from two cusps or else from three nodes.We may further consider the inflections and double tangents, as well in general as in regard to

**cubic**and quartic curves.The whole theory of the inflections of a

**cubic**curve is discussed in a very interesting manner by means of the canonical form of the equation x +y +z +6lxyz= o; and in particular a proof is given of Plucker's theorem that the nine points of inflection of a**cubic**curve lie by threes in twelve lines.It may be noticed that the nine inflections of a

**cubic**curve represented by an equation with real coefficients are three real, six imaginary; the three real inflections lie in a line, as was known to Newton and Maclaurin.For an acnodal

**cubic**the six imaginery inflections disappear, and there remain three real inflections lying in a line.For a crunodal

**cubic**the six inflections which disappear are two of them real, the other four imaginary, and there remain two imaginary inflections and one real inflection.For a cuspidal

**cubic**the six imaginary inflections and two of the real inflections disappear, and there remains one real inflection.The theory of the invariants and covariants of a ternary

**cubic**function u has been studied in detail, and brought into connexion with the**cubic**curve u = o; but the theory of the invariants and covariants for the next succeeding case, the ternary quartic function, is still very incomplete.Again, when there is in question only one pair of points or lines, these, if coincident, must be real; thus, b line meets a

**cubic**curve in three points, one of them real, and other two real or imaginary; but if two of the intersections coincide they must be real, and we have a line cutting a**cubic**in one real point and touching it in another real point.And it then appears that there are two kinds of non-singular

**cubic**cones, viz, the simplex, consisting of a single sheet, and the complex, consisting of a single sheet and a twin-pair sheet; and we thence obtain (as for**cubic**curves) the crunodal, the acnodal and the cuspidal kinds of**cubic**cones.And we then say that a curve consists of one or more circuits; thus the right line, or curve of the first order, consists of one circuit; a curve of the second order consists of one circuit; a

**cubic**curve consists of one circuit or else of two circuits.A non-singular

**cubic**is simplex, consisting of one odd circuit, or it is complex, consisting of one odd circuit and one even circuit.It at once appears from inspection of the figure of a non-singular

**cubic**curve, which is the odd and which the even circuit.The circular

**cubic**and the bicircular quartic, together with the Cartesian (being in one point of view a particular case thereof), are interesting curves which have been much studied, generally, and in reference to their focal properties.There are in some cases points termed centres, or singular or multiple foci (the nomenclature is unsettled), which are the intersections of improper tangents from the two circular points respectively; thus, in the circular

**cubic**, the tangents to the curve at the two circular points respectively (or two imaginary asymptotes of the curve) meet in a centre.It is a form of the theorem for the case D = r, that the coordinates x, y, z of a point of the bicursal curve, or in particular the co-ordinates of a point of the

**cubic**, can be expressed as proportional to rational and integral functions of the elliptic functions snu, cnu, dnu; in fact, taking the radical to be r -0 2 .r - k 2 0 2, and writing 8 =snu, the radical becomes = cnu, dnu; and we have expressions of the form in question.Thus, considering the several cases of a

**cubic**1.It is a leading point in the theory that a curve in space cannot in general be represented by means of two equations U= o, V = o; the two equations represent surfaces, intersecting in a curve; but there are curves which are not the complete intersection of any two surfaces; thus we have the

**cubic**in space, or skew**cubic**, which is the residual intersection of two quadric surfaces which have a line in common; the equations U= o, V= o of the two quadric surfaces represent the**cubic**curve, not by itself, but together with the line.The latter has an average calorific power of 1732 calories per

**cubic**metre, or 161 B.T.U.Further, certain

**cubic**crystals, such as sodium chlorate and bromate, and also some liquids and even vapours, rotate the plane of polarization of the light that traverses them, whatever may be the direction of the stream.The polarizability in
