The material loss inflicted on the French was not very great, but its effect in raising the moral of the raw Prussian cavalry and increasing their confidence in their old commander was enormous.
Though he had control of what remained of the navies of Holland and Spain, as well as of the French, he was outnumbered at every point, while the efficiency of the British fleet gave it a mobility which doubled its material superiority.
The abundant documents in the hands of her descendants, the families of Broglie and Haussonville, have indeed furnished material for books and papers, but these are almost wholly on the social aspect of Mme de Stael, not on her literary merit.
In 1846 he achieved high reputation by his Life of David Hume, based upon extensive and unused MS. material.
It was his great good fortune to find abundant unused material for his Life of Hume, and to be the first to introduce the principles of historical research into the history of Scotland.
Underneath the surface are beds of sand, gravel and clays, the last affording material for the manufacture of brick, tiles and pottery.
Callias And Hipponicus The exports from Callao are guano, sugar, cotton, wool, hides, silver, copper, gold and forest products, and the imports include timber and other building materials, cotton and other textiles, general merchandise for personal, household and industrial uses, railway material, coal, kerosene, wheat, flour and other food stuffs.
The Callao fortifications were bombarded by a Spanish fleet under Admiral Mendez Nunez on the 2nd of May 1866, when there were heavy losses both in lives and material.
The source of the carbon of organic tissues is carbonic acid; that of the nitrogen in the proteids is the nitrates, nitrites and salts of ammonia dissolved in sea-water; the material of the shells or other skeletons is the silica, phosphate and calcium of the salts of sea-water (and, in rare cases, the salts of strontium).
It follows, too, that when there is a number of substances, all essential for the elaboration of living material, and when one of these is present in minimal proportion, that one substance rules the production, just as the effective strength of a chain depends on the weakest link.
Since there is less of the indispensable food material in the warmer seas there is, therefore, less phyto-plankton.
Such material, it is suspected, may form the massive bases on which barrier or fringing or atoll reefs are built up.
In 1812 tools and material of war for his sieges were often insufficient.
For later traditional material, see Buxtorf, De Arca Focderis (Basel, 1659).
From such slender material it is not easy to form a clear conception of the saint's personality.
Bury has shown that both Tirechan and Muirchu drew from written material which existed in part at any rate in Irish.
In an age when, with the evolution of the feudal organization cf society, even everyday costume was becoming a uniform, symbolizing in material and colour the exact status of the wearer, it was natural that in the parallel organization of the Church the official vestments should undergo a similar process of differentiation and definition.
Up to the 9th century these had been very plain, without ornament save such traditional decorations as the clavi of the dalmatic; what splendour they had was due to their material and the ample folds of their draperies.
From the latter's time onward a host of liturgists took up the theme, arguing from the form, the material, the colour and the fashion of wearing the various garments to symbolical interpretations almost as numerous as the interpreters themselves.
The enormous increase in the commercial demand for rubber and the probability of the continuance of this increase in view of the great variety of purposes to which the material can be applied, has led to great activity in rubber planting in other parts of the world, especially in Ceylon and the Malay Peninsula and Archipelago, where the Para rubber trees (Hevea brasiliensis) has been successfully introduced, and numerous plantations; many of which have not been in existence for more than ten or fifteen years, are now contributing to the world's supply.
There can be little doubt that with a fall in price further uses for rubber would arise, leading to an increased demand, and among them may be mentioned its utilization as a road material.
The proteids should be as far as possible removed during the preparation of the rubber, as these substances are chiefly responsible for the objectionable smell and colour of " native " rubbers, and their presence leads to subsequent change in the commercial material.
All crude rubber contains more or less proteid, and in the opinion of some technical experts its presence even affords strength to the material, but this cannot be accepted as proved.
Sulphur when warmed with caoutchouc combines with it, and on this fact the vulcanization of rubber depends, and also the production, with an excess of sulphur, of the hard black material known as vulcanite or ebonite.
Double texture goods are made by uniting the rubber surfaces of two pieces of the coated material.
In order to make spongy or porous rubber, some material is incorporated which will give off gas or vapour at the vulcanizing temperature, - such as carbonate of ammonia, crystallized alum, and finely ground damp sawdust.
The travertine which forms round the springs of the Sarno was used even at Pompeii as building material.
In sedimentary rocks it occurs as detrital material.
For various purposes a manufactured material known as "micanite" or "micanite cloth" is much used; this consists of small sheets of mica cemented with shellac or other insulating cement on cloth or paper.
In working downwards in open quarries and in tortuous shafts and passages much of the mica is damaged, and a large amount of labour is expended in hauling waste material to the surface.
For this monumental work he had been gathering material for several years before the war.
At Bethersden, between Ashford and Tenterden, marble quarries were formerly worked extensively, supplying material to the cathedrals of Canterbury and Rochester, and to many local churches.
Massicot is the raw material for the manufacture of "red lead" or "minium."
His chief work is a Chronicon ad annum 1054, which furnishes important and original material for the history of the emperor Henry III.
His linguistic work indeed was always hampered by the lack of manuscript material, which is felt in his philological writings, e.g.
The permeability of most material substances differs very slightly from unity, being a little greater than I in paramagnetic and a little less in diamagnetic substances.
The coercive force, or coercivity, of a material is that reversed magnetic force which, while it is acting, just suffices to reduce the residual induction to nothing after the material has been temporarily submitted to any great magnetizing force.
It can be shown 3 that in a uniform field an elongated piece of any non-crystalline material is in stable equilibrium only when its length is parallel to the lines of force; for diamagnetic substances, however, the directing couple is exceedingly small, and it would hardly be possible to obtain a uniform field of sufficient strength to show the effect experimentally.
A primary coil of length 1, having n turns, is wound upon a cylinder made of non-conducting and non-magnetic material, and upon the middle of the primary a secondary or induction coil is closely fitted.
These are to be regarded merely as typical specimens, for the details of a curve depend largely upon the physical condition and purity of the material; but they show at a glance how far the several metals differ from and resemble one another as regards their magnetic properties.
This material can therefore exist in either of two perfectly stable conditions, in one of which it is magnetizable, while in the other it is not.
The question whether a corpuscle actually has a material gravitating nucleus is undecided, but there are strong reasons for believing that its mass is entirely due to the electric charge.
No material advance upon the knowledge recorded in Gilbert's book was made until the establishment by Coulomb in 1785 of the law of magnetic action.
Homoplasy can only be assumed when the coincidence is of a simple nature, and is such as may be reasonably supposed to have arisen by the action of like selective conditions upon like material in two separate lines of descent.'
Their anatomy has not been studied, as yet, by means of freshly-killed material, and is imperfectly known, though the presence of the coxal FIG.
By his mode of regarding a liquid as a material system characterized by the unshackled mobility of its minutest parts, the separation between the mechanics of matter in different forms of aggregation finally disappeared, and the fundamental equation of forces was for the first time extended to hydrostatics and hydrodynamics.'
Instead of following the motion of each individual part of a material system, he showed that, if we determine its configuration by a sufficient number of variables, whose number is that of the degrees of freedom to move (there being as many equations as the system has degrees of freedom), the kinetic and potential energies of the system can be expressed in terms of these, and the differential equations of motion thence deduced by simple differentiation.
Besides this most important contribution to the general fabric of dynamical science, we owe to Lagrange several minor theorems of great elegance, - among which may be mentioned his theorem that the kinetic energy imparted by given impulses to a material system under given constraints is a maximum.
The whole island is strewn with natural basaltic prisms, some of great size; and of this material, brought by boats or rafts from a distance of 30 m.
The flora includes mangroves, Rubiaceae, Sapotaceae and other forms requiring more than pure coralline material for their growth.
In the preparation of alum from clays or from bauxite, the material is gently calcined, then mixed with sulphuric acid and heated gradually to boiling; it is allowed to stand for some time, the clear solution drawn off and mixed with acid potassium sulphate and allowed to crystallize.
Fine white freestone abounds in the immediate vicinity (as at Craigleith, from the vast quarry of which, now passing into disuse, the stone for much of the New Town was obtained) and furnishes excellent building material; while the hard trap rock, with which the stratified sandstones of the Coal formation have been extensively broken up and overlaid, supplies good materials for paving and road-making.
The above constitutes the whole material which the earlier middle age had at its disposal.
In God, who is pure form without matter, the archetypes of material things exist as eternal immaterial forms. In this way Gilbert was at once Aristotelian and Platonist.
The first effects of this immense acquisition of new material were markedly unsettling on the doctrinal orthodoxy of the time.
Originality was at no time the strong point of the middle ages, but in the later period it was almost of necessity buried under the mass of material suddenly thrust upon the age, to be assimilated.
On the other hand, the influence of this new material is everywhere evident in the wider range of questions which are discussed by the doctors of the period.
The plaiters work up the material in a damp state, either into whole straw or split straw plaits.
The success of this enterprise was decisive and rapid, and the "Cobden prints" soon became known through the country as of rare value both for excellence of material and beauty of design.
The landless younger sons of the gentry and the Servian and Vlach immigrants provided him with excellent and practically inexhaustible military material.
Besides, his hands were tied by the unappeasable enmity of the emperor and the emperor's allies, and he could never count upon any material help from the West against the East.
Moreover, the next century and a half was a period of domestic tranquillity, during which Hungary was able to repair the ruin of the long Turkish wars, nurse her material resources, and take the first steps in the direction of social and political reform.
For the medieval history of Hungary the Mdtydskori diplomatikai emlekek (Diplomatic Memorials of the Time of Matthias Corvinus), issued by the academy under the joint editorship of Ivan Nagy and Baron Albert Nyary, affords interesting material.
Though he was much indebted to Aristotle he used the material to advantage, adding much from his own experience and historical knowledge.
In general he deserves the praise of steadily keeping in view the higher aims and interests of society in connexion with the regulation and development of its material life.
The Romans, who succeeded the Greeks as the chief civilized power in Europe, failed to set store on their literary and scientific treasures; mathematics was all but neglected; and beyond a few improvements in arithmetical computations, there are no material advances to be recorded.
The ancient city walls have been almost entirely destroyed in recent times to provide building material,' and the place is famous for the discoveries made in its tombs.
Finally, it brought the simplest living matter or formless protoplasm before the mental vision as the startingpoint whence, by the operation of necessary mechanical causes, the highest forms have been evolved, and it rendered unavoidable the conclusion that this earliest living material was itself evolved by gradual processes, the result also of the known and recognized laws of physics and chemistry, from material which we should call not living.
The failure of the material carrying a positive character to divide so as to distribute itself among all the reproductive cells of a hybrid individual, and the limitation of its distribution to half only of those cells, must prevent the swamping " of a newly appearing character in the course of the inter-breeding of those individuals possessed of the character with those which do not possess it.
It is no discovery that this latter kind of variation is not hereditable, and it is not the fact that the small variations, to which Darwin attached great but not exclusive importance as the material upon which natural selection operates, are of this latter kind.
But his long reign is unstained by a single ignoble deed, and he devoted himself heart and soul to the promotion of the material and spiritual welfare of Denmark.
Under these conditions there is no doubt that the star would appear to be fairly resolved, since the brightness of its external ring system is too small to produce any material confusion, unless indeed the components are of very unequal magnitude.
A comparison with the method of a material pointer, attached to the parts whose rotation is under observation, and viewed through a microscope, is of interest.
In an engraved glass grating there is no opaque material present by which light could be absorbed, and the effect depends upon a difference of retardation in passing the alternate parts.
Under these circumstances, if the material of the grating be completely transparent, the whole of the light must appear in the direct image, and the ruling is not perceptible.
To save the diamond point it might be possible to use something softer than ordinary glass as the material of the plate.
The only practically available raw material for 'the extraction of uranium is pitchblende (q.v.).
Ammonium uranate heated to redness yields pure U308, which serves as a raw material for uranium compounds.
The efforts made by the administration to restore the Boers to the land, to develop the material resources of the country, and to remove all barriers to the intellectual and moral development of the people, were soon, however, hampered by severe Economic commercial depression.
The broad distinctions which, as a matter of fact, exist between every known form of living substance and every other component of the material world, justify the separation of the biological sciences from all others.
To tin cast-iron articles they must be decarburetted superficially by ignition within a bath of ferric oxide (powdered haematite or similar material), then cleaned with acid, and tinned by immersion, as explained above.
It is frequently found upon deities, kings and magnates, and appears to have been composed of some thick furrowed or fluted material, sometimes of bright and variegated design.
A small charge of dry guncotton will, however, detonate the wet material, and this peculiarity is made use of in the employment of guncotton for blasting purposes.
A charge of compressed wet guncotton may be exploded, even under water, by the detonation of a small primer of the dry and waterproofed material, which in turn can be started by a small fulminate detonator.
The explosive wave from the dry guncotton primer is in fact better responded to by the wet compressed material than the dry, and its detonation is somewhat sharper than that of the dry.
Gaullieur in the same review in 1857, and all the available material is utilized in a monograph on her and her work by P. Godet, Madame de Charriere et ses amis (2 vols., Geneva, 1906).
The fruit is edible and its juice is made into beer; the sap of the tree is made into wine, and its pith into bread; the leaves furnish an excellent thatch, and the fibre extracted from their midribs is used f or fish lines, cordage, hammocks, nets, &c.; and the wood is hard and makes good building' material.
The cell body, or cytoplasm, is apparently composed of a fine reticulum or network, containing within the meshes a soft viscid, transparent substance, the cell-sap, or hyaloplasm, which is probably a nutrient material to the living cell.
Their principal function is to bring about the removal of foreign, dead or degenerating material.
Where the material is too large to be taken up by an individual cell, the dissolution is brought about by the cells surrounding the material, to which they closely apply themselves, and by the secreting of the ferment, a gradual process of erosion is brought about with ultimate absorption.
There is neither any absolute difference nor a constancy in their chemical reactions, and there can be brought about a transition of the " colloid " material into the " mucoid," or conversely.
In certain pathological conditions an excessive formation and discharge of such material is usually associated with catarrhal changes in the epithelium.
In the normal thyroid there is formed and stored up in the spaces this colloid material.
These vesicles are filled with the colloid material (x 90 diam.) J FIG.
There is no evidence that this material is brought by the circulating blood and infiltrates the tissues.
Generally it is either dried, after being separated from the wash water, by means of common salt, upon a layer of which the moist nitroglycerin is gently run and allowed to drain or filter through, or it is filtered through a mass of dry sponge or similar dry and porous material.
The material (limestone) was quarried on the spot.
Great importance was also attached to chemically prepared remedies as containing the essence or spiritual quality of the material from which they were derived.
In 1872, Hoppe-Seyler (1825-1895) gave a new beginning to our knowledge of the chemistry of secretion and of excretion; and later students have increased the range of physiological and pathological chemistry by investigations not only into the several stages of albuminoid material and the transitions which all foodstuffs undergo in digestion, but even into the structure of protoplasm itself.
All phenomena, moral as well as material, are contemplated by him in their relation to one great organic whole, which he acknowledges under the name of "Natura daedala rerum," and the most beneficent manifestations of which he seems to symbolize and almost to deify in the "Alma Venus," whom, in apparent contradiction to his denial of a divine interference with human affairs, he invokes with prayer in the opening lines of the poem.
Much of the material was obtained from the destroyed houses of the unfortunate Jews, but the stone for the bulwarks was obtained from Caen, and the small bricks or tiles from Flanders.
In reply to Rudolf Hospinian's Concordia discors (1607), he wrote a work, rich in historical material but one-sided in its apologetics, Concordia concors (1614), defending the formula of Concord, which he regarded as inspired.
When the rocks are concealed by detrital material he looks for outcroppings on steep hillsides, on the crests of hills or ridges, in the beds of streams, in landslides, in the roots of overturned trees, and in wells, quarries, roadcuttings and other excavations.
Rock-filling will be used whenever a large proportion of barren material must be mined with the ore.
With soft material, pillars must be large, even at moderate depths below the surface, and it involves less labour to leave long rectangular pillars than to form numerous Pillar- square ones.
In steep pitching beds sufficient excavated material is allowed to remain in the stope for the support of the machines and men, the excess being drawn out from time to time and loaded into cars.
The ore as mined is hand-picked and the barren material allowed to remain in the stope where it falls.
When rock filling is available, as when the ore contains much barren material to be left behind in mining, the ore body is divided into blocks of convenient height as above, and these blocks are divided into floors, the bottom floor of each block however being attacked.
The cost of filling has been greatly reduced by the system of flushing culm, sand, gravel and similar material, through pipes leading from the surface into mine workings.
Where practicable steam shovels are employed, even when it is necessary to break up the material beforehand by blasting.
At Anzac, where conditions favoured the retreating troops less, it had been necessary to destroy some valuable war material at the last moment, and a few worn-out guns had purposely been abandoned.
The work of removing stores, war material, animals and personnel was to be carried out on successive nights, the fighting force ashore was to be gradually reduced, the front line of trenches was to be held up till the very last - the final night being fixed provisionally for the 8th-9th - and the detachments vacating it were to hurry straight off to the beaches.
It ought also to be mentioned that there was a greater accumulation of impedimenta at Helles than there had been at either Anzac or Suvla, so that even if the weather were to remain favourable, it was certain that material of great value would have to be destroyed to prevent its falling into the enemy's hands.
He began a "History of his Native District of Northern Wiltshire," but, feeling that he was too old to finish it as he would wish, he made over his material, about 1695, to Thomas Tanner, afterwards bishop of St Asaph.
In this way is produced the crystalline, devitrified material, known as Reaumur's porcelain.
Owing to the physical changes produced in the material exposed prolonged observations of temperature are impossible.
The material and technique suggest a close relationship to porcelain.
In a sheet-glass tank there is therefore a gradient of temperature and a continuous passage of material from the hotter end of the furnace where the raw materials are introduced to the cooler end where the glass, free from bubbles and raw material, is withdrawn by the gatherers.
The demand constantly increases, and, owing to constant improvements in material in the moulds and in the methods of working, the supply fully keeps pace with the demand.
This smooth surface is then brilliantly polished by the aid of friction with a rubbing tool covered with a soft substance like leather or felt and fed with a polishing material, such as rouge.
The material has been considered by some to be magnetic iron ore and by others oxide of manganese.
A more important outcome, however, of Italian influence was the production, in emulation of Venetian glass, of a glass made of refined potash, lime and sand, which was more colourless than the material it was intended to imitate.
Glass-cutting was a craft imported from Germany, but the English material so greatly surpassed Bohemian glass in brilliance that the Bohemian cut-glass was eclipsed.
The case has been the converse of that of the Romans; the latter had no fine pottery, and therefore employed glass as the material for vessels of an ornamental kind, for table services and the like.
The advance in its material prosperity has been especially rapid since the incorporation of Saxony in the German Zollverein.
Parallel experiments with layers of dough or sand plus some connecting material proved that the particles in all cases moved along the same tracks as would be followed by a flowing cylinder of liquid.
In the design of a structure such as a tall reservoir dam it is important that the line of thrust in the material should pass inside the core of a section, so that the material should not be in a state of tension anywhere and so liable to open and admit the water.
Looking somewhat deeper at the sources from which Old English law was derived, we shall have to modify our classification to some extent, as the external forms of publication, although important from the point of view of historical criticism, are not sufficient standards as to the juridical character of the various kinds of material.
Assyria in this, as in other matters, the servile pupil of Babylonia, built its palaces and temples of brick, though stone was the natural building material of the country, even preserving the brick platform, so necessary in the marshy soil of Babylonia, but little needed in the north.
The publication of fresh chronological material in 1906 and 1907 placed a new complexion on the problems at issue, and enabled us to correct several preconceptions, and to reconcile or explain the apparently conflicting data.
Among the chief editions are those of Zahn, Der Hirt des Hermas (1868); Gebhardt and Harnack, Patres Apostolici (1877, with full bibliographical material); Funk, Patres Apost.
On this should be laid at least a foot thick of coarse, hard, rubbly material, a layer of rough turf, grass side downwards, being spread over it to prevent the compost from working down.
The details of manufacture of sugar from canes and of sugar from beetroots differ, but there are five operations in the production of the sugar of commerce from either material which are common to both processes.
There is a great deal of valuable material for the history of Mahmud and his policy in the unpublished F.O.
Such alterations in temperature produce strains which frequently result in the chipping off of small fragments of the material composing the stone.
On descending into the substratum the finer material decreases and more stones are met with; farther down are seen larger fragments of unaltered rock closely packed, and this brash or rubble grades insensibly into the unbroken rock below.
Such river-transported material or alluvium is common in all river valleys.
Most of the material termed " sand " in such analyses consists of particles ranging in diameter from .5 to.
Whereas the soil used to be looked upon solely as a dead, inert material containing certain chemical substances which serve as food constituents.
By their continued action the soil becomes enriched with nitrogenous material which eventually through the nitrification process becomes available to ordinary green crops.
Later the nitrogen-content of the nodule decreases, most of the organisms, which are largely composed of proteid material, becoming digested and transformed into soluble nitrogenous compounds which are conducted to the developing roots and seeds.
The material which chemists call calcium carbonate is met with in a comparatively pure state in chalk.
When recommendations are made about liming land it is necessary to indicate more precisely than is usually done which of the three classes of material named above - chalk, quicklime or slaked lime - is intended.
Land which contains less than about z /c, of lime usually needs the addition of this material.
Such a material would not only have an influence on the texture of the land but the lime would reduce the sourness of the land and the phosphate of lime supply one of the most valuable of plant foodconstituents.
The material is dug from neighbouring pits or sometimes from the fields which are to be improved, and applied in autumn and winter.
Great care is necessary to prevent the heaps from becoming too hot, in which case the clay becomes baked into hard lumps of brick-like material which cannot be broken up. With careful management, however, the clay dries and bakes, becoming slowly converted into lumps which readily crumble into a fine powder, in which state it is spread over and worked into the land at the rate of 40 loads per acre.
The warp consists of fine muddy sediment which is suspended in the tidal river water and appears to be derived from material scoured from the bed of the Humber by the action of the tide and a certain amount of sediment brought down by the tributary streams which join the Humber some distance from its mouth.
The growing crops should be ploughed in before flowering occurs; they should not be buried deeply, since decay and nitrification take place most rapidly and satisfactorily when there is free access of air to the decaying material.
Many of them seem to have been admitted to membership. They were regarded as merchants, for they bought raw material and sold the manufactured commodity; no sharp line of_ demarcation was drawn' between the two classes in the 12th and 13th centuries.
He wrote a poem on agriculture (De re rustica) in fourteen books, the material being derived from Columella and other earlier writers.
The cut tobacco is now roasted, partly with the view of driving off mositure and bringing the material into a condition for keeping, but also partly to improve its smoking quality.
For roll, twist of pigtail tobacco the raw material is damped or sauced as in the case of cut tobacco.
The material is supplied to the twisting machinery by an attendant, and formed into a cord of uniform thickness, twisted and wound on a drum by mechanism analogous to that used in rope-spinning.
In making cigars by the hand, the operator rolls together a sufficient quantity of material to form the filling of one cigar, and experience enables him or her to select very uniform quantities.
This quantity is wrapped in the inner cover, an oblong piece of leaf the length of the cigar to be made, and of width sufficient to enclose the whole material.
The material is moistened with a solution of common salt and placed in very large heaps to ferment for some weeks.
The material as mined will probably not average over 10 per cent.
The shares, when made of the same material, required constant sharpening; this necessity was removed by the device, patented by Robert Ransome in 1803, of chilling and so hardening the under-surface of the share; the upper surface, which is soft, then wears away more quickly than the chilled part, whereby a sharp edge is always assured.
The site has been partially excavated by the Palestine Exploration Fund, and an enormous mass of material for the history of Palestine recovered from it, including remains of a pre-Semitic aboriginal race, a remarkably perfect High Place, the castle built by Simon, and other remains of the first importance.
They seem to have understood them at once, and, like much else Roman, to have made them their own with out material change.
In 1905 Anderson ranked first among the cities of the state in the manufacture of carriage and wagon material, and iron and steel.
The other feature, peculiar to the long poem (gasida, elegy), is that, whatever its real object, whatever its metre, it has a regular scheme in the arrangement of its material.
For the chronology before the year ho of the Flight Wagidi did his best, but here, the material being defective, many of his conclusions are precarious.
The fact that energy is being used at so high a rate as Too H.P. on so small a charge of material sufficiently indicates that the furnace is only used for experimental work, or for the fusion of metals which, like tungsten or chromium, can only be melted at temperatures attainable by electrical means.
The temperature of the electric furnace, whether of the arc or incandescence type, is practically limited to that at which the least easily vaporized material available for electrodes is converted into vapour.
The electric furnace has several advantages as compared with some of the ordinary types of furnace, arising from the fact that the heat is generated from within the mass of material operated upon, and (unlike the blastfurnace, which presents the same advantage) without a large volume of gaseous products of combustion and atmospheric nitrogen being passed through it.
Ordinarily carbon is used as the electrode material, but when carbon comes in contact at high temperatures with any metal that is capable of forming a carbide a certain amount of combination between them is inevitable, and the carbon thus introduced impairs the mechanical properties of the ultimate metallic product.
Liquid metal coming in contact with such a surface forms a crust of solidified metal over it, and this crust thickens up to a certain point, namely, until the heat from within the furnace just overbalances that lost by conduction through the solidified crust and the cathode material to the flowing water.
In such an arrangement, after the first instant, the melted metal in the furnace does not come in contact with the cathode material.
But whereas, from its construction, the Siemens furnace was intermittent in operation, necessitating stoppage of the current while the contents of the crucible were poured out, many of the newer forms are specially designed either to minimize the time required in effecting the withdrawal of one charge and the introduction of the next, or to ensure absolute continuity of action, raw material being constantly charged in at the top and the finished substance and by-products (slag, &c.) withdrawn either continuously or at intervals, as sufficient quantity shall have accumulated.
The Germans recognized the staple rights of Bruges for a number of commodities, such as wool, wax, furs, copper and grain, and in return for this material contribution to the growing commercial importance of the town, they received in 1309 freedom from the compulsory brokerage which Bruges imposed on foreign merchants.
Vienna is the intellectual as well as the material capital of Austria - emphatically so in regard to the German part of the empire.
Much of the Arabic material has been collected and translated by Fraehn, "Veteres Memoriae Chasarorum" in Mem.
For thirty-six years Creevey had kept a "copious diary," and had preserved a vast miscellaneous correspondence with such people as Lord Brougham, and his step-daughter, Elizabeth Ord, had assisted him, by keeping his letters to her, in compiling material avowedly for a collection of Creevey Papers in the future.
This is a history in four books, the material for which was mainly drawn from the anonymous Gesta Francorum, but some valuable information has been added by Baudry.
The Narrative contains much interesting material concerning the manners and customs i This discovery was made on the 19th of January 1840, one day before Dumont d'Urville sighted Adelie Land about 400 m.
The same qualities appear in Walton's Considerator Considered (1659), a reply to the Considerations of John Owen, who thought that the accumulation of material for the revision of the received text tended to atheism.
Almost all the towns of Tunisia were originally Roman or romanized Berber settlements; consequently the remains of Roman buildings form a large part of the material of which their existing structures are composed.
Their number is estimated at 150,000 to 300,000, divided into 112 tribes, and differing widely in habits, customs and material condition.
Long ditches with stone-paved sluices for washing this mineral-bearing material have long been used by the Indians, who also construct stone bars across the beds of the streams to make riffles and hold the deposited grains of gold.
The Incas had made much progress in weaving, and specimens of their fabrics, both plain and coloured, are to be found in many museums. The Spanish introduced their own methods, and their primitive looms are still to be found among the Indians of the interior who weave the coarse material from which their own garments are made.
This led to a material reduction in the army, which, as reorganized, consists of 4000 officers and men, divided into seven battalions of infantry of 300 men each, seven squadrons of cavalry of 125 men each, and one regiment of mountain artillery of 590 men, with six batteries of mountain guns.
After a regular term of office of six years of peace and moral and material progress Castilla resigned, and General Jose Echenique was elected president.
The details of the plant - the material and fittings of the still, the manner of heating, the form of the condensing plant, receivers, &c. - have to be determined for each substance to be distilled in order to work with the maximum economy.
Sometimes linings of enamelled iron or other material are employed, which when worn can be replaced at a far lower cost than that of a new still.
Before the object can pierce the dense lower strata of air its material is usually exhausted, but on rare occasions it withstands the fiery ordeal, and fragments of the original mass fall upon the earth.
The walls and the palace, still perfect in the beginning of the 19th century, were gradually pulled down for building material, and in 1882 there remained only a small part of the walls, from which all the outer stones had been removed, while the palace was a ruin.
On the 7th of November he fought his first battle as a commander, that of Belmont (Missouri), which, if it failed to achieve any material result, certainly showed him to be a capable and skilful leader.

The provincial government has established ironworks for the manufacture of rails and other railway material.
On the degeneration of the polypide, its nutritive material is apparently absorbed for the benefit of the zooid, while the pig mented substances assume a spheroidal form, which either remains as an inert "brown body" in the body-cavity or is discharged to the exterior by the alimentary canal of the new polypide.

This glacial material is in the form of a till or boulder clay, but in the lowlands, and especially along Narragansett Bay, it is generally overlaid by stratified drift deposited by glacial streams. Within Narragansett Bay are the numerous islands characteristic of an area which has suffered comparatively recent depression, the largest being Rhode Island (or Aquidneck), Conanicut Island and Prudence Island.
Material difficulties now, however, for the first time intruded on his path.
As a sort of theoretic basis for this adhesion to national type in literature, he conceived the idea that literature and art, together with language and national culture as a whole, are evolved by a natural process, and that the intellectual and emotional life of each people is correlated with peculiarities of physical temperament and of material environment.

Both are highly valued for the sake of the shell, which has always been a favorite material for ladies combs and hairpins.
It was a labor of loving service, untouched by the spirit of material gain, conferring upon the work of the older masters a dignity and poetic feeling which we vainly seek in much of the later work.
He probably worked some two generations before the time of Moronobu, but there is no reason to believe that his labors had any material share in determining the creation and trend of the new school.
It consists of fifteen volumes, which appeared at intervals from 1812 to 1875, twelve being published during his life, and the others from material left by him.
Stone has never been in favor in Japan as a material for the higher expression of the sculptors art.
The frec end of the hilt was crowned with a metallic cap or pommel (kashira), the other extremity next the tsuba was embraced by an oval ring (fuchi), and in the middle was affixed on each side a special ornament called the menuki, all adapted in material and workmanship to harmonize with the guard.
The metallic bowl and mouthpiece of the pipe offered a tempting surface for embellishment, as well as the clasp of the pouch; and the netsuke, being made of wood, ivory or other material susceptible of carving, also gave occasion for art and ingenuity.
From the time when they began to cast bronze statues, Japanese experts understood how to employ a hollow, removable core round which the metal was run in a skin just thick enough for strength without waste of material; and they also understood the use of wax for modelling purposes.
The employment of mother-of-pearl to, ornament lacquer grounds dates from a period as remote as the 8th century, but its use as a material for constructing decorative designs began in the 17th century, and was due to an expert called Shibayama, whose descendant, Shibayama SOichi, has in recent years been associated with the same work in TOkyO.

Exquisite as was already his susceptibility to beauty and his mastership of the rarest poetic material, we cannot doubt that Chenier was preparing for still higher flights of lyric passion and poetic intensity.
The most obvious distinction is that the animal cell-wall is either absent or composed of a nitrogenous material, whereas the plant cell-wall is composed of a carbohydrate material - cellulose.
The animal and the plant alike require food to repair waste, to build up new tissue and to provide material which, by chemical change, may liberate the energy which appears in the processes of life.
An animal may be defined as a living organism, the protoplasm of which does not secrete a cellulose cell-wall, and which requires for its existence proteid material obtained from the living or dead bodies of existing plants or animals.
The term "alloy" does not necessarily imply obedience to the laws of definite and multiple proportion or even uniformity throughout the material; but some alloys are homogeneous and some are chemical compounds.
The two ingredients revealed by this process are not pure copper and pure tin, but each material contains both metals.
This uniform distribution of a solid substance throughout the mass of another, so as to form a homogeneous material, is called " solid solution," and we may say that solid silver can dissolve copper.
This is the case with the copper-tin alloys containing less than 9% by weight of tin; a microscopic examination reveals only one material, a copper-like substance, the tin having disappeared, being in solution in the copper.
Steels containing as much as 12% of tungsten are now used as a material for tools intended for turning and planing iron and steel.
Although the age did not afford free scope and stimulus to individual energy and enterprise, it furnished more material and social advantages for the peaceful cultivation of letters.

Railways and material were destroyed, the country cleared of supplies, and the Confederate government severed from its western states.
He constructed two equal condensers, each consisting of a metal ball enclosed in a hollow metal sphere, and he provided also certain hemispherical shells of shellac, sulphur, glass, resin, &c., which he could so place in one condenser between the ball and enclosing sphere that it formed a condenser with solid dielectric. He then determined the ratio of the capacities of the two condensers, one with air and the other with the solid dielectric. This gave the dielectric constant K of the material.
A continuous stream of gas, supplied at a constant pressure and temperature, is forced through a porous plug, from which it issues at a lower pressure through an orifice carefully surrounded with non-conducting material, where its temperature is measured.
The larger stones having been removed by hand, gyratory motion is given to the pan by a combination of shaking and twisting movements so as to keep its contents suspended in the stream of water, which carries away the bulk of the lighter material, leaving the heavy minerals, together with any gold which may have been present.
The material of the bank being loosened by blasting and the cutting action of the water, crumbles into holes, and the superincumbent mass, often with large trees and stones, falls into the lower ground.
It then passes through screens and grizzlies to retain the coarse gravel, the finer material passing on to sluice boxes provided with riffles, supplied with mercury.
The discharge of the comminuted material takes place through an aperture, which is covered by a thin steel plate perforated with numerous slits about Ath in.
After charging, the barrel is rotated, and when the chlorination is complete the contents are emptied on a filter of quartz or some similar material, and the filtrate led to settling tanks.
This species usually constructs its nest on the bottom, excavating a hollow in which a bed of grass, rootlets or fibres is prepared; walls are then raised, and the whole is roofed over with the like material.

In the young historian's eyes these good brethren were of much value as living and breathing historic material.
This work obliged him to trace out, collect, arrange, and digest a great mass of incongruous material scattered on both sides of the Atlantic, a large portion of which was in manuscript, and required much tedious exploration and the employment of trained copyists.
Some of these are doubtless such as no botanist, with adequate material for forming an opinion, would accept; but, after making the necessary deductions for actual mistakes and misstatements, there still remains a large number upon which legitimate differences of opinion prevail.
The geological formations thus exposed show that the plateaus are composed of a base of eruptive material, overlaid by enormous deposits of reddish sandstones, conglomerates and quartzites, exposed in parts to a depth of 2000 feet.

An ordinary commander would have avoided fighting altogether, but Marlborough saw beyond the material conditions and risked all on his estimate of the moral superiority of his army and of the weakness of the French leading.
Not merely were artistic sculptures and bas-reliefs found that demonstrated a high development of artistic genius, but great libraries were soon revealed, - books consisting of bricks of various sizes, or of cylinders of the same material, inscribed while in the state of clay with curious characters which became indelible when baking transformed the clay into brick.
Meanwhile, the material found by Botta and Layard, and other successors, in the ruins of Nineveh, has been constantly augmented through the efforts of companies of other investigators, and not merely Assyrian, but much earlier Babylonian and Chaldaean texts in the greatest profusion have been brought to the various museums of Europe and America.
As the forgotten history of Oriental antiquity has been restored to us, it has come to be understood that, politically speaking, the Hebrews were a relatively insignificant people, whose chief importance from the standpoint of material history was derived from the geographical accident that made them a sort of buffer between the greater nations about them.
It is material to observe, that as the Olympic years and periods begin with the 1st of July, the first six months of a year of our era correspond to one Olympic year, and the last six months to another.
He had to face the dominant fact of the situation - the aggressive pressure of Germany at a time when Russia was drifting into an internal crisis of the first magnitude and was unable to concentrate the material and moral forces required in the coming conflict.
Artillery and bridging material were brought forward and wire-cutting commenced, while a series of partial infantry attacks took place with the object of securing suitable jumping-off ground.

In 1826 Dumas devised a method suitable for substances of high boiling-point; this consisted in its essential point in vaporizing the substance in a flask made of suitable material, sealing it when full of vapour, and weighing.
By varying the material of the bulb, this apparatus is rendered available for exceptionally high temperatures.
The policy of opposing uncivilized tribes by the construction of the limes, a raised embankment of earth or other material, intersected here and there by fortifications, was not his invention, but it owed in great measure its development to him.
In 1905 the wage-earners engaged in manufacturing (under the factory system) numbered 18,475, and the total capital invested in manufacturing was $50,925,630; the gross value of products was $41,160,276; the net value (deducting the value of material purchased in partly manufactured form) was $16,276,470.
Charlemagne's wars in Italy, Spain and Saxony formed part of the common epic material, and there are references to his wars against the Sla y s; but especially he remained in the popular mind as the great champion of Christianity against the creed of Mahomet, and even his Norman and Saxon enemies became Saracens in current legend.
The contest between Charlemagne and Widukind (Guiteclin) offered abundant epic material.
It became then desirable to make the head of steel for sake of uniformity of material, and the advantages of steel in lightness and rigidity for the tube then became evident.
On the other hand, since much of the material of an apocalypse is a reinterpretation, it is necessary to distinguish between its original meaning and the new turn given to it in the Apocalypse.
At times details in the transmitted material are unintelligible to our author, and these in some cases he omits referring to in his interpretation.
The presence of such details is strong evidence of the writer's use of foreign material.
Nor is it possible to accept Gunkel's theory in Schiipfung and Chaos as an adequate explanation, who explained the author's conviction of the truth of his message as springing always from the fact that he was dealing with traditional material.
Thus the three groups form parallel accounts and contain the same or closely related material.
But between the sixth and seventh seals and the sixth and seventh trumpets the connexion is more or less disturbed by the insertion of certain interludes containing material foreign in certain aspects to the Apocalypse.
In other words, it has been taken over from pre-existing material - either Christian or Jewish - and the materials of which it is composed are ultimately derived from non-Jewish sources - either Babylonian, Greek or Egyptian - and bore therein very different meanings from those which belong to them in their present connexion.
Various devices have consequently been attached to leads intended to catch and hold the material when soft enough to be penetrated.
Similar effects are produced along the boulder-clay cliffs of the Baltic. Where the force of the waves on the beach produces its full effect the coarser material gets worn down to gravel, sand and silt, the finest particles remaining long suspended in the water to be finally deposited as mud in quiet bays.
Pure calcareous sand and calcareous mud are formed by wave action on the shores of coral islands where the only material available is coral and the accompanying calcareous algae, crustacea, molluscs and other organisms secreting carbonate of lime.
In the Atlantic it is the characteristic deposit of the slopes of continental shelves of western Europe and of New England, being largely mixed with ice-borne material to the south of Newfoundland.
As well as the finest of terrigenous clay there is present in sea-water far from land a different clay derived from the decomposition of volcanic material.
To this inconceivably slowly-growing deposit of inorganic material over the ocean floor there is added an overwhelmingly more rapid contribution of the remains of calcareous and siliceous planktonic and benthonic organisms, which tend to bury the slower accumulating material under a blanket of globigerina, pteropod, diatom or radiolarian ooze.
Amongst the foreign material found embedded in the red clay are globules of meteoric iron, which are sometimes very abundant.
This fact, together with the extraordinarily rare occurrence of such remains and meteoric particles in globigerina ooze, although there is no reason to suppose that at any one time they are unequally distributed over the ocean floor, can only be explained on the assumption that the rate of formation of the epilophic deposits through the accumulation of pelagic shells falling from the surface is rapid enough to bury the slowgathering material which remains uncovered on the spaces where the red clay is forming at an almost infinitely slower rate.
He covered the bulb of the thermometer with layers of non-conducting material and left it immersed at the desired depth for a very long time to enable it to take the temperature of its surroundings.
Following the suggestion of Cavendish, Irving made observations of deep temperature on Phipps's Spitsbergen voyage of 1773 with a valved water-bottle, insulated by non-conducting material.
The first comprehensive study of the currents of the Atlantic was that carried out by James Rennell (1790-1.830), and since that time Findlay in his Directories, Heinrich Berghaus, Maury and the officials of the various Hydrographic Departments have produced increasingly accurate descriptions of the currents of the whole ocean, largely from material supplied by merchant captains.
Soon after 1540 he entered the household of the famous Cortes, who supplied him with most of the material for his Historia de las Indias (1552), and Cronica de la conquista de Nueva Espana (1552).
If there is no external world, the distinction between substance and accidents vanishes, and these become the sole essence of material objects, so that there is no room for any change whilst they remain as before.
They equally affirm that the so-called representative image is the sole reality, and discard as unthinkable the unperceiving material cause of the philosophers.
As cause of our sensations and ground of our belief in externality, he substituted for an unintelligible material substance an equally unintelligible operation of divine power.
The evidence therefore of these bores (3 and 4) indicates some material derangement, which is then proved by other bores, either towards the dip or the outcrop, according to the judgment of the borer, so as to ascertain the best position for sinking pits.
As each stage is worked out, the floor level is connected with that next below it by means of an incline, which facilitates the introduction of the packing material.
The material for filling may be the waste from earlier workings stored in the spoil banks at the surface; where there are blast furnaces in the neighbourhood, granulated slag mixed with earth affords excellent packing.
In this the filling material, preferably sand, is sent down from the surface through a vertical steel pipe mixed with sufficient water to allow it to flow freely through distributing pipes in the levels commanding the excavations to be filled; these are closed at the bottom by screens of boards sufficiently close to retain the packing material while allowing the water to pass by the lower level to the pumping-engine which returns it to the surface.
The roof of the excavation is supported as the coal is removed, by packing up the waste material, and by a double row of props, 2 ft.
In securing the roof and sides of coal workings, malleable iron and steel are now used to some extent instead of timber, although the consumption of the latter material is extremely large.
The value of his work consists not only in the stores of material which he collected, but also in the success with which he dealt with many of the problems raised by the inscriptions.
The crucible is of metal and considerably larger than the ingot, the latter being surrounded by a mass of unreduced material which protects the crucible from the intense heat.
Pure crystalline calcium carbide yields 5.8 cubic feet of acetylene per pound at ordinary temperatures, but the carbide as sold commercially, being a mixture of the pure crystalline material with the crust which in the electric furnace surrounds the ingot, yields at the best 5 cubic feet of gas per pound under proper conditions of generation.
The purity of the carbide entirely depends on the purity of the material used in its manufacture, and before this fact had been fully grasped by manufacturers, and only the purest material obtainable employed, it contained notable quantities of compounds which during its decomposition by water yielded a somewhat high pro portion of impurities in the acetylene generated from it.
This takes place when in the manufacture of the carbide the material is kept too long in contact with the arc, since this overheating causes the dissociation of some of the calcium carbide and the solution of metallic calcium in the remainder.
There is no unreduced material, and the process is considerably simplified, while less expensive plant is required.
The second process is one patented by Fritz Ullmann of Geneva, who utilizes chromic acid to oxidize the phosphuretted and sulphuretted hydrogen and absorb the ammonia, and this method of purification has proved the most successful in practice, the chromic acid being absorbed by kieselgiihr and the material sold under the name of "Heratol."
Dr Wolff employs purifiers in which the gas is washed with water containing calcium chloride, and then passed through bleaching-powder solution or other oxidizing material.
The introduction of acetylene dissolved under pressure in acetone contained in cylinders filled with porous material drew attention again to this use of the gas, and by using a special construction of blowpipe an oxy-acetylene flame is produced, which is far hotter than the oxy-hydrogen flame, and at the same time is so reducing in its character that it can be used for the direct autogenous welding of steel and many minor metallurgical processes.
Among his publications, besides many sermons, were A Brief Review of the Episcopal Church in Virginia (1845); Wilberforce, Cranmer, Jewett and the Prayer Book on the Incarnation (1850); Reasons for Loving the Episcopal Church (1852); and Old Churches, Ministers and Families of Virginia (1857); a storehouse of material on the ecclesiastical history of the state.
